CHEHARDY, C.J.
Defendant-appellant, Joseph Ross, appeals his convictions and sentences for
crimes involving a juvenile under the age of thirteen. For the reasons that follow,
we affirm defendant’s convictions and sentences. However, due to an error patent,
we remand to the district court to correct the sentencing minute entry to designate
count one as a crime of violence.
STATEMENT OF THE CASE
On September 8, 2022, the Jefferson Parish District Attorney filed a bill of
information charging defendant with sexual battery upon a known juvenile, where
the child was under the age of thirteen, in violation of La. R.S. 14:43.1 (count one);
oral sexual battery upon a known juvenile, where the child was under the age of
thirteen, in violation of La. R.S. 14:43.3 (count two); and indecent behavior with a
juvenile under thirteen, in violation of La. R.S. 14:81 (count three). At the
September 26, 2022 arraignment, defendant pled not guilty.1
On June 30, 2025, the State filed a Notice of Intent to Call Expert Witness.
On August 7, 2025, defense counsel filed a “Demand for Daubert/Foret[2] Hearing
Upon Proffered State Expert ‘Dr.’ Anne Delores Troy,” as well as a Motion in
Limine Prohibiting State Witness(es) from Expressing Opinions Regarding the
Veracity of Complaints or Validity of Accusation. On August 11, 2025, before trial
commenced, the judge stated that a Daubert hearing had been satisfied and that she
would allow Dr. Troy to testify, after which defense counsel noted his objection.
The trial judge also granted defendant’s motion in limine, and trial began. On
August 13, 2025, the jury found defendant guilty as charged on all counts.
1
On August 11, 2025, before jury selection began, the State amended the bill of information to
correct the victim’s date of birth on all counts from May 20, 2008 to May 29, 2008. Defendant
re-tendered his plea of not guilty to the amended bill of information.

26-KA-60 1
Defense counsel filed a Motion for Post Verdict Judgment of Acquittal or
Motion for a New Trial, a Motion for Downward Departure Pursuant to Dorthey,3
a Motion to Reconsider Sentence, and a Notice of Intent to Take Appeal and
Request for Appointment of Counsel. On September 18, 2025, the trial court heard
arguments regarding the Motion for Post Verdict Judgment of Acquittal or Motion
for a New Trial and denied the motions. Defendant waived the 24-hour sentencing
delay. The trial judge denied the motion for downward departure and sentenced
defendant to 25 years imprisonment at hard labor on each of counts one through
three, without the benefit of parole, probation, or suspension of sentence. The court
ordered the sentences to be served concurrently with one another and concurrently
with any other sentence defendant was currently serving. Thereafter, the trial judge
denied the motion to reconsider sentence. On September 22, 2025, the trial court
granted defendant’s motion for appeal.
On appeal, defendant challenges the trial court’s failure to hold a Daubert
hearing and its ruling permitting Dr. Anne Troy to testify.
FACTS
At trial, the jury heard live testimony from the victim, Z.W.; her mother,
J.R.; and a number of other parties involved with the case.4 The jury also watched
the video of the victim’s initial disclosure of the sexual abuse to a case manager in
Nevada.

State v. Dorthey, 623 So.2d 1276 (La. 1993).
4
The victim in this matter will be referred to by her initials, Z.W. In the interest of protecting
crime victims who are minors as well as victims of sexual offenses, as set forth in La. R.S.
46:1844(W)(3), only the victim’s initials will be used. See State v. R.W.B., 12-453 (La. 12/4/12),
105 So.3d 54. See also Uniform Rules of Court—Courts of Appeal, Rule 5-2. Compare State v.
E.J.M., III, 12-774, 12-732 (La. App. 5 Cir. 5/23/13), 119 So.3d 648, 652 n.1 (stating that this
Court has adopted a policy that its published work “will use only initials to identify the victim
and any defendant or witness whose name can lead to the victim’s identity (i.e., parent, sibling,
or relative with the same last name as the victim.)”). We refer to Z.W.’s mother by her initials,
J.R., due to allegations that she also was a victim of sexual abuse in the past. See La. R.S.
46:1844(W)(3).
26-KA-60 2
Abby Easterday testified that she was a case manager for Washoe County
Juvenile Services in Reno, Nevada. On November 5, 2021, she met with Z.W. and
her mother, J.R. Earlier that week, J.R. called the juvenile services center to look
for resources for Z.W. because she noticed a change in her behavior. During their
discussion, Ms. Easterday asked Z.W. if she had ever been a victim of any sexual
or physical abuse. Ms. Easterday explained that Z.W. nodded her head and stated
that she had been sexually abused when she was approximately nine years old by
her grandfather, defendant Joseph Ross, in Louisiana. Ms. Easterday asked J.R.,
Z.W.’s mother, if the abuse had ever been reported before, and she indicated that it
had not. Ms. Easterday stated that J.R. indicated that she did not doubt the abuse
occurred, because the “same thing” happened to her by defendant. Ms. Easterday
testified that she was a mandatory reporter and informed J.R. that she needed to
make the report regarding the sexual abuse allegations involving Z.W. in the
jurisdiction where the abuse occurred. Ms. Easterday later confirmed that J.R.
reported the allegations of sexual abuse in Jefferson Parish.
J.R. testified that defendant is her father, and that she and her siblings
suffered sexual and mental abuse by defendant when they were young. J.R. stated
that the sexual abuse started when she was approximately six or seven years old
until she was approximately thirteen or fourteen.
J.R. testified regarding various incidents of sexual abuse by defendant,
including defendant putting his mouth on her “private area” and forcing her to
drive his car while sitting on his lap wearing only a big t-shirt. J.R. testified that on
multiple occasions, defendant forced her and her sister to insert dildoes vaginally
and anally and “wear them” throughout the night. She stated that defendant also
forced her and her sister to perform oral sex on each other and on a friend.
J.R. detailed another occasion when her family lived in Baton Rouge, and
she helped defendant at an abandoned house with air conditioning work when she
26-KA-60 3
was approximately twelve or thirteen. She testified that defendant forced her to
work in the attic with just a shirt on, and later to bathe and lie naked on a mattress.
J.R. stated that she believed neighbors may have called the police because officers
arrived at the abandoned house at that point. The authorities called her mother, and
she went to the police station. J.R. stated that she could not recall any other details
about the incident, but she recalled testifying in a courtroom in relation to the
incident and being scared. She testified that she was instructed to suppress her
experiences and was told that testifying was not good for the family dynamic.5
J.R. testified that when her family moved to Reno during Covid, Z.W.
started acting out, ran away, and attempted to commit suicide. J.R. sought help at a
juvenile center, and it was at this location that Z.W. disclosed that she was sexually
abused. J.R. explained that Z.W. had not disclosed any details of the abuse to her
previously, and that she never forced Z.W. to reveal those details because J.R. also
was a victim of trauma, and she wanted her daughter to “speak her truth” when she
was ready. J.R. testified that she allowed her parents to watch her children, even
after being sexually abused by defendant, because she did not have any help. She
testified that she trusted her mother, but she never allowed defendant to care for the
children by himself.
The jury also heard from Z.W., who testified that her date of birth was May
29, 2008. She stated that when her family was living in Houma, Louisiana, she and
her siblings would spend most weekends at their grandparents’ house without their
mother. She explained that she and her siblings would sleep in the extra room
across from their grandparents’ bedroom. Z.W. stated that her family moved to
Reno when she was twelve years old, in 2020. She explained that she was not
5
Officer Sherman Jackson testified that he investigated the sexual assault in 2004 involving J.R.
and defendant. He stated that J.R. denied that defendant had done anything to her, and DNA
results from the rape kit performed on her indicated that there was no evidence of a sexual
assault.
26-KA-60 4
happy to move, and she ran away twice, once to her boyfriend’s house, and another
time to her best friend’s house where she remained for five days. She also cut her
wrists with scissors. She explained that there was a lot going on, and she did not
know how to handle her emotions. Z.W. testified that her mother took her to meet
with Ms. Easterday, where she disclosed that defendant had sexually abused her.
After the disclosure, she met with an interviewer at the Children’s Advocacy
Center (CAC) in Nevada.6
Z.W. testified that she was about seven or eight years old the first time
defendant sexually abused her. She stated that she was lying down in her
grandparents’ bed with her siblings watching T.V. when defendant got in bed with
them and told her to lie next to him. She complied, and defendant grabbed her
hand, put it inside his pants, and made her touch his penis. Z.W. asked him what
“that” was. She stated that defendant then pulled his penis from his boxers and
showed it to her. He then continued to make her rub it. She stated that he put her
on top of him, held her waist, and moved her on top of him. Z.W. stated that
defendant then took her to the bathroom and said he needed to show her
something. He locked the door, pulled his penis out of his boxers again, and told
her to touch it. She complied. Z.W. testified that defendant told her to sit on the
toilet and to pull down her underwear. He proceeded to perform oral sex on her by
putting his mouth on her vagina. Z.W. stated that her grandmother came upstairs,
knocked on the bathroom door, and asked defendant what he was doing. Defendant
replied that he was just showing Z.W. something. Her grandmother left and went
back downstairs. Z.W. testified that she could not recall how she left the bathroom.
Z.W. recalled another incident of sexual abuse that occurred at her
grandparents’ house. She testified that many family members were at the house for
6
Z.W.’s CAC interview, which was admitted into evidence at trial, was largely consistent with
her trial testimony regarding the abuse.
26-KA-60 5
a football game, and defendant asked her to go upstairs and do a favor for him. She
complied and went to his bedroom. Defendant told her to sit in the “spinning chair”
next to his bed and to take her underwear and shorts off. She again complied. Z.W.
testified that defendant sat on the side of the bed facing her and had her put her
legs up. She explained that defendant grabbed lotion from the nightstand, put it on
his hands, and rubbed her vagina with it. Z.W. stated that at one point, one of her
uncles came up the stairs, and defendant told her to quickly put her clothes back
on. She complied and sat on the chair. Her uncle came into the room and asked
what was going on. Defendant stated that they were just having a conversation.
On another occasion, Z.W. stated that she and her siblings were sleeping in
the same bed, and she woke up to her grandparents arguing. Z.W. heard defendant
coming upstairs, and she pretended to be asleep at the end of the bed. She testified
that defendant opened the door, put his hand underneath her shirt, and touched her
“all over her chest.” She explained that defendant kissed her neck and licked her
ear. Z.W. testified that her siblings were all asleep while this occurred.
Detective Biana Robinson testified that she was a detective in the special
victim’s unit of the Jefferson Parish Sheriff’s Office (JPSO). She became involved
in the investigation when someone in another state made a report of sexual abuse
involving Z.W. After Z.W. disclosed that defendant sexually abused her, Detective
Robinson authored an arrest warrant for him. Defendant was arrested, and
Detective Robinson met with him and read him his Miranda7 rights, which he
waived.
During his statement to Detective Robinson, defendant said he had no
problems with any of his children or grandchildren. He explained that on one
occasion, his daughter J.R. got upset at him for kissing her children goodnight, but

26-KA-60 6
she still brought them around him. He admitted to being accused of a sex crime
against J.R. in Baton Rouge, but he explained that J.R. stated that nothing
happened. He denied ever sexually abusing Z.W.
Dr. Anne Troy was accepted as an expert in the field of child abuse and
child abuse pediatrics. She testified that she did not examine Z.W. and was not
familiar with the facts surrounding the allegations in this case. Dr. Troy explained
that when a child came to the childcare center, a statement would be taken from the
child regarding the abuse, and the child would undergo a physical examination.
Dr. Troy discussed various factors to be considered when determining
whether a victim’s disclosure was consistent with child sexual abuse. When
determining a diagnosis, she would eliminate other hypotheses. For example, she
may inquire whether a parent had mental illness or a history of trauma, and she
would ask sensory questions about the abuse and inquire about possible coaching.
Dr. Troy stated that the time between the abuse and the victim’s disclosure of the
abuse could depend on the identity of the perpetrator. She stated that in many
cases, the perpetrator is known to the child. She testified that some reasons for
delayed disclosures are naivety of the child or feelings of shame and guilt.
ISSUES PRESENTED FOR REVIEW
Defendant assigns two errors on appeal: (1) The trial court committed
reversible error by allowing the State’s expert nurse practitioner, Anne Troy, to
give an expert opinion on how she determines the credibility of child sex victims
and the veracity of their accusations, which improperly bolstered the complaining
witness’s testimony and violated defendant’s right to a fair trial; and (2) The trial
court failed to perform its gatekeeping role when it refused a Daubert hearing on
the State’s expert nurse practitioner, Anne Troy, which violated the Appellant’s
right to a fair trial by allowing the State to present a litany of unreliable and
conclusory expert opinion evidence, which not only far exceeded the scope of the
26-KA-60 7
expert’s proficiency, but also violated the Daubert standards, disregarding well-
established scientific methods and principles that ensure that expert opinions are
reliable and grounded in sufficient facts and data.
DISCUSSION
Both of defendant’s assignments of error involve the qualification of Dr.
Troy as an expert witness and the subject matter of her expert testimony. As such,
we first discuss the parties’ pre-trial motions related to Dr. Troy’s testimony. We
then address defendant’s second assignment of error before the first assignment of
error.
On June 30, 2025, the State filed a Notice of Intent to Call Expert Witness,
indicating the intent to call Dr. Troy as an expert in child abuse pediatrics. The
State attached Dr. Troy’s curriculum vitae and explained in its brief:
Dr. Troy will testify regarding whether injuries are expected in
children who are victims of sexual abuse. Dr. Troy will testify
about normal behaviors associated with children and expected
clinical observations of such behaviors. Dr. Troy will also
testify regarding childhood development and how childhood
experiences impact the types of children experiencing child
sexual abuse. Dr. Troy will also testify regarding disclosures in
child sex abuse cases, specifically the reasons why disclosures
in child sex abuse cases are often delayed. Dr. Troy will testify
regarding trauma bonding and how child sex abuse victims
respond to trauma. Dr. Troy will testify to the grooming that
occurs to children and adolescents by offenders.
On August 7, 2025, defendant filed a Demand for Daubert/Foret Hearing
and a Motion in Limine. In the Demand, defendant argued that a Daubert hearing
should be held before jury selection to address Dr. Troy’s qualifications as an
expert. Counsel for defendant stated that his “late recognition” of the need for a
hearing was due to the State’s “purposeful” designation of Dr. Troy as a “doctor”
in its Notice of Intent to Call Expert Witness. He averred that upon further inquiry,
he discovered Dr. Troy was a nurse practitioner and not a doctor. In the motion in
limine, defense counsel asked the trial court to instruct Dr. Troy not to offer her
26-KA-60 8
personal opinion regarding the validity or veracity of the victim’s allegations
against defendant.
On August 11, 2025, before jury selection began, the trial court heard
arguments regarding defendant’s motion in limine.8 Defense counsel indicated that
the State had provided neither an expert report from Dr. Troy nor any materials on
which she relied when forming an opinion; thus, she could not be allowed to testify
as an expert. Defense counsel further argued that Dr. Troy had no publications in
any of the areas for which the State proposed to offer her as an expert, and that this
was “expert by ambush.” He contended that Dr. Troy was being called solely for
the purpose of bolstering the validity of the victim’s accusations.
The State responded that its “719 motion” outlined the topics Dr. Troy’s
testimony would cover. The State explained that Dr. Troy did not examine the
victim in this case and that she would testify only as to general concepts related to
delayed disclosures, trauma bonding, coaching, and how child predators operate.
The State argued that La. C.Cr.P. art. 719 requires only notice, and many occasions
arise in which experts have not generated a report but have testified consistently
with the “719 notice.” The State further stated that Dr. Troy would not testify to
the ultimate matter of fact or whether the victim was being truthful. Instead, Dr.
Troy would testify regarding concepts that may be difficult for a lay person to
understand.
The trial court determined that the State had satisfied its obligations under
La. C.Cr.P. art. 719, and stated, “I believe we’ve had a Daubert hearing now and
I’m going to allow Dr. Anne Troy to testify.” The trial court indicated that if Dr.
8
The trial court expressed surprise that defense counsel waited until the morning of trial to take
issue with the State’s expert. Defense counsel replied that he was deceived by the title of
“doctor” accompanied by “Children’s Hospital,” and that the State purposefully designated her
that way.
26-KA-60 9
Troy testified to irrelevant subject matter or issues that did not apply to this case,
defense counsel could object at that time.
Defense counsel also referenced C.M.J. v. L.M.C, 14-1119 (La. 10/15/14),
156 So.3d 16, 26, a Louisiana Supreme Court case in which the Court stated that
Dr. Troy’s testimony lacked so much credibility, it would not be considered. The
trial court responded that Dr. Troy had testified in her division before and that she
was aware of C.M.J. Defense counsel objected to the trial court’s ruling regarding
the Daubert hearing. Thereafter, the court granted defense counsel’s motion in
limine, explaining that Dr. Troy would not be permitted to offer her personal or
professional opinion regarding the validity or credibility of the victim’s
allegations.9
Dr. Troy’s Trial Testimony
At trial, after extensive direct examination of Dr. Troy and cross-
examination by defense counsel regarding her qualifications, the trial court
accepted Dr. Troy as an expert in the field of child abuse and child abuse
pediatrics. Defense counsel objected. The State asked:
Q: So Dr. Troy, to be clear, did you examine the victim in this
case?
A: No, I did not.
Q: Okay. Are you familiar with the facts surrounding the
allegations in this case?
A: No, I can’t speak to them at all.
Q: All right. So let’s talk about just in generalities[.]
Dr. Troy proceeded to discuss the process of what occurs when a child
comes to the CAC and the value of taking a medical history of a child. She testified
that she had seen thousands of children in her career and discussed what she would

Defendant argued in the Motion for Post Verdict Judgment of Acquittal or Motion for New
Trial that the trial court failed to conduct a Daubert hearing. The trial court denied both post-
verdict motions. Defendant does not challenge these rulings on appeal.

expect to find in a physical examination. The record reflects that the State
indicated it would not ask about the veracity of the victim in this case, because Dr.
Troy never interviewed this victim. Defense counsel renewed his objection.
Dr. Troy discussed various factors she considers when determining the
veracity of a victim’s allegations. She also testified in general regarding coaching,
the timing of a victim’s disclosures, and the reasons for a victim’s delayed
disclosure. She discussed potential inconsistencies in a child’s account of abuse,
recollection of dates of abuse, blended memory, and responses to trauma. She also
explained how sexual offenders operated with regard to children and discussed
grooming.
Denial of Daubert Hearing (Second Assignment of Error)
Defendant argues on appeal that the trial court erred by “rubberstamping”
Dr. Troy’s expert testimony without regard for “even a cursory” Daubert inquiry.
He contends the trial court failed to ask about several topics of expertise and
whether they had been tested or subjected to peer review. Defendant also argues
that the trial court failed to inquire into her experience and qualifications as to the
topics set forth in the State’s notice. Defendant again contends the trial court
ignored C.M.J. v. L.M.C., 14-1119 (La. 10/15/14), 156 So.3d 16, 26, a case in
which the Louisiana Supreme Court gave Dr. Troy’s interview methods no weight
and stated that her opinion was flawed because it was not based on reliable
evidence.
Defendant argues that the court’s denial of a Daubert hearing prejudiced him
by allowing Dr. Troy to present court-sanctioned expert testimony under an “aura
of expertise.” He argues that her opinions were riddled with conjecture and
sweeping generalizations about how child predators operate and about grooming.
Defendant contends that Dr. Troy’s 48-page curriculum vitae does not mention
child grooming, child predator behavior, or any other related topics. He asserts that
26-KA-60 11
if the trial court had conducted a Daubert inquiry or performed its gatekeeping
role, none of the testimony would have been permitted. He argues that, at the very
least, the trial court could have issued a limiting instruction. Defendant argues that
the failure to grant a Daubert hearing prejudiced him and violated his right to a fair
trial.
The State responds that Louisiana courts have long accepted expert
testimony in the field of forensic pediatrics and child abuse, and the jurisprudence
reflects that courts have found no abuse of discretion where a trial court has
declined to conduct a Daubert hearing before admitting expert testimony
concerning child sexual abuse. The State avers that the Daubert factors are not
necessarily applicable to every case or to all experts. The State points out that Dr.
Troy’s testimony outlined general behavioral characteristics of child sexual abuse
victims, and her opinions were grounded in specialized knowledge, experience,
training, and education. The State contends that it provided more than a sufficient
foundation for admitting Dr. Troy’s testimony without a Daubert hearing. Further,
even if the trial court erred by not conducting a Daubert hearing, any error was
harmless.
In State v. Foret, 628 So.2d 1116, 1123 (La. 1993), the Louisiana Supreme
Court adopted the test set forth in Daubert regarding proper standards for the
admissibility of expert testimony, which require the trial court to act in a
gatekeeping function to ensure that any and all scientific testimony or evidence
admitted is not only relevant, but reliable. State v. Boudoin, 11-967 (La. App. 5
Cir. 12/27/12), 106 So.3d 1213, 1225, writ denied, 13-255 (La. 8/30/13), 120 So.3d
260. The Daubert inquiry consists of four considerations: (1) whether the theory or
technique can be and has been tested; (2) whether the theory or technique has been
subjected to peer review and publication; (3) the known or potential rate of error;
26-KA-60 12
and (4) whether the methodology is generally accepted by the relevant scientific
community. Id.
The trial court may consider one or more of the four Daubert factors, but the
list of factors neither necessarily nor exclusively applies to all experts or in every
case. Kumho Tire Co., Ltd. v. Carmichael, 526 U.S. 137, 141-42, 119 S.Ct. 1167,
1171, 143 L.Ed.2d 238 (1999). Rather, the law grants a district court “the same
broad latitude when it decides how to determine reliability as it enjoys in respect to
its ultimate reliability determination.” Id. Competence of an expert witness is a
question of fact to be determined within the sound discretion of the trial judge
whose rulings on the qualifications of expert witnesses will not be disturbed absent
an abuse of discretion. State v. Augustus, 25-296 (La. App. 5 Cir. 2/25/26), 432
So.3d 292, 317.
In State v. Francois, 13-616 (La. App. 5 Cir. 1/31/14), 134 So.3d 42, 59-60,
writ denied, 14-431 (La. 9/26/14), 149 So.3d 261, this Court discussed the
Louisiana Supreme Court’s recognition of the limitation of the Daubert inquiry in
Cheairs v. State ex rel. Dep’t of Transp. & Dev., 03-0680 (La. 12/3/03), 861 So.2d
536, 541-42:
The Cheairs Court observed that Daubert only addresses the
reliability of the methodology used by the expert, not the adequacy of
the expert’s qualifications. Id. at 542. Therefore, the court adopted a
broader three-prong inquiry developed by the U.S. Eleventh Circuit
“to more fully assist [trial] courts in determining all the relevant issues
related to the admissibility of expert testimony[.]” Id. This three-
prong inquiry was first set forth in City of Tuscaloosa v. Harcros
Chemicals, Inc., 158 F.3d 548 (11th Cir. 1998), in which the Court
stated that the admission of expert testimony is proper only if all three
of the following are true:
(1) [T]he expert is qualified to testify competently regarding the
matters he intends to address; (2) the methodology by which the
expert reaches his conclusions is sufficiently reliable as determined by
the sort of inquiry mandated in Daubert; and (3) the testimony assists
the trier of fact, through the application of scientific, technical, or
specialized expertise, to understand the evidence or to determine a
fact in issue.
26-KA-60 13
In State v. Johnson, 52,128 (La. App. 2 Cir. 8/15/18), 253 So.3d 887, 899,
the Second Circuit noted “a crucial difference between questioning the
methodology employed by an expert witness and questioning the application of
that methodology or the ultimate conclusions derived from that application. Only a
question of the validity of the methodology employed brings Daubert into play.”
The party demanding a pretrial Daubert hearing requesting the determination of
the reliability of evidence must set forth sufficient allegations showing the
necessity for such a determination. Id. The trial court, in its discretion, can
determine on a case-by-case basis if a Daubert hearing is necessary to test the
reliability of expert testimony. State v. McQuarter, 19-594 (La. App. 5 Cir.
11/25/20), 305 So.3d 1055, 1076.
In State v. Perilloux, 21-448 (La. App. 5 Cir. 12/20/23), 378 So.3d 280, 305,
writ denied, 24-104 (La. 9/4/24), 391 So.3d 1055, the defendant argued that the
trial court erred when it allowed expert testimony on the concept of grooming
without first conducting a Daubert hearing to test its reliability. Before trial, the
State filed a motion in limine asking the trial court to allow expert testimony to
explain the general concept of grooming and delayed reporting/disclosure of abuse
in child sexual abuse cases. Id. at 306. In response, the defendant filed a motion for
a Daubert hearing seeking to limit the testimony of the State’s expert, Kim
Madden, claiming that testimony on this issue was unreliable. At the hearing, the
State explained that it intended to introduce the expert testimony only as to the
general concept of grooming and would not elicit any specific testimony analyzing
the defendant’s behavior in that case. The defendant contended the expert
testimony was unnecessary because it involved common-sense issues that would
not assist the jury. But the trial court determined that the expert testimony would
assist the jury and found that a Daubert hearing was not necessary to test the
reliability of the testimony, because Louisiana courts recognized the general
26-KA-60 14
concept of grooming in child sex abuse matters. Id. at 307. The trial court granted
the State’s motion in limine to allow general expert testimony on grooming and
denied the defendant’s request for a Daubert hearing. Id.
On appeal in Perilloux, this Court explained that at trial, the defendant did
not contest Ms. Madden’s qualifications as an expert, question the reliability of her
testimony with specificity, or explain why a Daubert hearing was necessary,
especially when both experts had agreed to the relevancy of grooming in child sex
abuse cases. The Court indicated that the concept of grooming was not a matter of
common sense, and the expert’s testimony was important to assist the jury. At trial,
the defendant had an unlimited opportunity to question Ms. Madden regarding her
methodologies and qualifications, but he did not elicit any information that would
lead the trial court to question the reliability of her testimony on grooming. As
such, this Court determined the trial court did not abuse its discretion in denying
the defendant’s request for a Daubert hearing and found Ms. Madden’s testimony
was relevant, reliable, and helpful to the jury in analyzing the evidence. Id.
Here, although the trial court indicated that a Daubert hearing occurred,
defendant claims no such hearing occurred. Indeed, the record does not reflect that
a Daubert hearing was held. Nevertheless, as in Perilloux, we find the trial court
did not abuse its discretion by allowing Dr. Troy to testify without first conducting
a Daubert hearing.10

After stating that the Daubert hearing had been satisfied, the trial court explained that Dr. Troy
previously had testified as an expert in her division. The court also indicated that it was aware of
the Louisiana Supreme Court’s ruling in C.M.J., affirming a trial court’s ruling that no weight
should be given to Dr. Troy’s testimony where Dr. Troy conducted a forensic interview of three
children at the mother’s request. Id. at 23. At trial in C.M.J., Dr. Troy testified that she did not
conduct a “forensic interview” of the children and only conducted “medical incident histories.”
Id. at 25. The court found that Dr. Troy’s testimony was to be given no weight because evidence
and testimony elicited at trial “established that the history given to [Dr. Troy] by the mother was
inaccurate and the children’s interviews were flawed and occurred long after the children were
contaminated” in the case. Id. at 26. We find the context and circumstances in C.M.J. are readily
distinguished from the present case.

Before the trial court accepted Dr. Troy as an expert in the field of child
abuse and child abuse pediatrics, Dr. Troy testified as to her extensive education,
knowledge, and research in the field of child abuse. She stated that she had been a
nurse for fifty years and taught forensic nursing for seventeen years. She explained
that she previously was a sexual assault nurse examiner and received training for
500 hours in the area of child maltreatment. Dr. Troy also testified that she had
been qualified as an expert in the field of child maltreatment (including child
physical abuse, sexual abuse, delayed disclosure, and neglect) over 180 times
throughout Louisiana, Texas, Mississippi, and Virginia. Further, the record reflects
that defense counsel had ample opportunity to cross-examine Dr. Troy before the
trial court accepted her as an expert. However, during cross-examination, defense
counsel did not question Dr. Troy as to her methodology or the reliability of her
opinions, instead asking only if she was paid a fee to appear in court and if she had
participated in this case.
Dr. Troy’s testimony was also general in nature. She testified generally
regarding various characteristics of a child sexual-abuse victim, but she did not
present any case-specific opinions regarding Z.W.’s allegations involving
defendant. Dr. Troy’s general testimony regarding grooming, delayed disclosure,
and coaching constituted scientific, technical, or other specialized knowledge that
helped the trier of fact understand the evidence or determine a fact at issue. See La.
C.E. art. 702; Perilloux, 378 So.3d 280. We cannot say the trial court erred in
permitting Dr. Troy to testify at trial in this matter without first conducting a
Daubert hearing.
Alternatively, even if the trial court erred in failing to conduct a Daubert
hearing, we find the error was harmless. Z.W.’s accounts of sexual abuse by
defendant were largely consistent. In the absence of internal contradiction or
irreconcilable conflict with physical evidence, one witness’s testimony, if believed

by the trier of fact, is sufficient for a conviction. See State v. Banks, 17-358 (La.
App. 5 Cir. 3/14/18), 241 So.3d 1240, 1250, writ denied, 18-586 (La. 3/25/19), 267
So.3d 599, cert. denied sub nom. Banks v. Louisiana, 589 U.S. 978, 140 S.Ct. 268,
205 L.Ed.2d 140 (2019). At the conclusion of trial, the trial court instructed the
jurors that they were the sole judges of the law and facts on the question of guilt
and innocence, and they alone were to determine the weight and credibility of the
evidence and testimony of any witness and expert witness. Despite defendant’s
arguments at trial regarding factual inconsistencies in K.W. and J.R.’s testimony,
the jury evidently found Z.W.’s testimony credible.
Admission of Dr. Troy’s Testimony (First Assignment of Error)
Defendant additionally argues that the trial court erred when it allowed Dr.
Troy to testify regarding the veracity and credibility of a child sexual abuse victim.
He avers that Dr. Troy’s testimony bolstered Z.W.’s credibility and violated his
right to a fair trial. Defendant argues that Foret applies while also acknowledging
that Dr. Troy did not testify whether Z.W. was sexually abused. Defendant argues
that the expert in Foret used the exact same language that the State used here when
questioning Dr. Troy. Defendant contends that because Dr. Troy’s testimony
improperly bolstered Z.W.’s claims and violated his right to a fair trial, his
convictions and sentences should be reversed.
The State responds that Dr. Troy’s testimony fell well within the permissible
scope of expert testimony in child sexual abuse cases, and claims that defendant
ignores the context of Dr. Troy’s testimony. The State also distinguishes the cases
that defendant cites, again noting that Dr. Troy provided only general testimony
regarding certain characteristics associated with child sexual abuse victims; she did
not provide an assessment as to Z.W.’s credibility or determine whether she had
been sexually abused.

Admission of expert testimony is controlled by La. C.E. art. 702(A), which
states:
A witness who is qualified as an expert by knowledge, skill,
experience, training, or education may testify in the form of an
opinion or otherwise if the proponent demonstrates to the court
that it is more likely than not that:
(1) The expert’s scientific, technical, or other specialized
knowledge will help the trier of fact to understand the evidence
or to determine a fact in issue;
(2) The testimony is based on sufficient facts or data;
(3) The testimony is the product of reliable principles and
methods; and
(4) The expert’s opinion reflects a reliable application of the
principles and methods to the facts of the case.
Furthermore, La. C.E. art. 704 states, in pertinent part, that “in a criminal
case, an expert witness shall not express an opinion as to the guilt or inno
