COMMISSIONER’S REPORT AND RECOMMENDATION THAT
DEFENDANT’S FOURTH MOTION FOR POSTCONVICTION RELIEF
SHOULD BE SUMMARILY DISMISSED
AND
DEFENDANT’S MOTION TO TRANSPORT EVIDENCE FOR DEFENSE
FORENSIC TESTING SHOULD BE DENIED
Andrew Vella, Esquire, Deputy Attorney General, Department of Justice,
Wilmington, Delaware, Attorneys for the State.
Christopher S. Koyste, Esquire, Law Offices of Christopher S. Koyste, LLC,
Attorney for Defendant Michael D. Broomer
PARKER, Commissioner
For the reasons set forth below, Defendant Michael D. Broomer’s fourth
motion for Rule 61 postconviction relief should be summarily dismissed, and his
motion to transport evidence for defense forensic testing should be denied.
INTRODUCTION
Pending before the Court are two companion motions. In the first motion,
Broomer’s fourth Rule 61 motion for postconviction relief, Broomer claims that the
discovery of a new witness satisfies the actual innocence exception to the procedural
bars preventing consideration of this motion on its merits and should result in the
reversal of his conviction and a retrial. As to Broomer’s second, companion motion,
Broomer requests that he permitted to perform gunshot residue (“GSR”) testing on
the victim’s clothing.
Broomer claims that the testimony of the new witness bolsters his justification
defense, and the GSR testing may also bolster his justification defense, in the event
that the GSR testing were to provide positive results.1
In this case, Broomer and his co-defendant Atiba Mayfield were charged with
Murder in the First Degree and other related charges in the shooting death of
Raekwan Mangrum on April 4, 2015. The State’s theory of the case was that
1
See, D.I. 184, Broomer’s Fourth Amended Rule 61 Motion, at * 10-11, 40.
1
Broomer was the driver of the vehicle and Mayfield was the triggerman that
intentionally killed Mangrum in a drive-by-shooting.2
Broomer and Mayfield were tried separately. At Broomer’s trial, Broomer
did not dispute that he was the driver of the vehicle and that Mayfield was the shooter
that shot and killed Mangrum.3 Broomer’s defense focused solely on his intent/state
of mind at the time his co-defendant shot and killed Mangrum, and his co-
defendant’s intent/state of mind at the time of the shooting.4 Following Mayfield’s
trial, Mayfield was convicted of Murder in the First Degree and related charges.
Following Broomer’s trial, Broomer’s defense proved to be partially successful.
Broomer was found guilty of Murder in the Second Degree and related charges.
Broomer’s co-defendant, Mayfield, during briefing on his first Rule 61
motion, located a new witness, Tyrie Burton, who claimed that he had been at the
scene of the shooting and his testimony appeared to bolster Mayfield’s (and
Broomer’s) justification/self defense claims. Because the existence of the new
witness was raised in Mayfield’s first Rule 61 motion, Mayfield was not faced with
the same pleading requirements preventing consideration of the claim on its merits
as Broomer is now facing in his fourth Rule 61 motion.

In Mayfield’s first Rule 61 motion, the Superior Court considered the merits
of Mayfield’s claim and thereafter denied Mayfield’s motion finding that the
testimony of the new witness was not persuasive.5 The Delaware Supreme Court
agreed with the Superior Court on Mayfield’s appeal.6
Broomer now raises the existence of this same witness in his pending fourth
Rule 61 motion and claims that the “actual innocence” exception allows him to
overcome the procedural bars preventing consideration of this claim on its merits.
The actual innocence exception provides that a defendant’s second or subsequent
Rule 61 motion should not be summarily dismissed if the defendant pleads with
particularity that new evidence exists that creates a strong inference that the movant
is actually innocent in fact of the acts underlying the charges of which he was
convicted.7
However, the actual innocence exception cannot be satisfied by new
testimony that only bolsters a defendant’s justification and/or self-defense claims.
To satisfy the actual innocence exception, the new evidence requires more than
innocence of intent, it requires a showing that the new evidence is sufficiently

persuasive to establish that the State convicted the wrong person. That some person
other than the petitioner committed the crime.8
Here, Broomer cannot satisfy the actual innocence exception. It was
undisputed that the State did not convict the wrong person. It was undisputed that
Broomer was the driver of the vehicle, and his co-defendant Mayfield, was the
triggerman that shot and killed Mangrum. Broomer’s defenses pertained solely to
his intent/state of mind at the time of the shooting and that of his co-defendant’s.
The testimony of the new witness seeks only to bolster Broomer’s justification
and/or self-defense claims. Broomer seeks to use the new witness to bolster
Broomer’s defense that he, and his co-defendant, lacked the requisite intent to be
convicted of murder at the time of the shooting.9
As to Broomer’s request to conduct GSR testing on the victim’s clothing, the
fact that GSR testimony was not performed on the victim’s clothing was known to
Broomer at the time of his trial in 2016, over 10 years ago. Broomer raised the
failure to perform GSR testing on the victim’s body and clothing in his first Rule 61
motion, which was decided in 2021,10 and then again in 2022, in his second Rule 61

motion.11 The lack of GSR testing of the victim’s clothing is not “new” or “recently
discovered.”12
Even if the request to perform GSR testing on the victim’s clothing was
somehow new or recently discovered (which it is not), Broomer still cannot meet the
threshold pleading requirement for proceeding to the merits of this request. Broomer
claims that this “new evidence” would further bolster his justification defense, if the
testing proved to be positive. But, as previously discussed, “new” evidence
proffered to bolster a defendant’s justification defense does not satisfy the actual
innocence exception to the pleading requirements.
Broomer has no path forward. It was undisputed that Broomer was the driver
and his co-defendant the shooter in the shooting death of the victim. Broomer cannot
satisfy the “actual innocence” exception to the pleading requirements for proceeding
with these motions. He does not allege, nor could he, that someone other than he
and his co-defendant committed the underlying acts in fact for which they were
charged. In accordance with the mandates of Rule 61, Broomer’s pending motions
should be summarily dismissed as they fail to meet the pleading requirements for
proceeding with this successive Rule 61 motion.

FACTS
Until shortly before the homicide which occurred on April 4, 2015, Broomer,
his co-defendant Mayfield, the victim Mangrum and another individual Nicodermus
Morris were all on good terms.13 Two incidents soured the relationships among
them. The first incident, which occurred on March 21, 2015, involved an altercation
between Mangrum and Mayfield. On that date, all four individuals were riding
together around Wilmington in a car jointly owned by Mangrum and Broomer.
When they stopped for gas, an argument over who was going to drive started
between Mangrum and Mayfield. The argument ended after Mangrum retrieved a
.380 handgun and shot Mayfield in the leg.14
The second incident involved bad blood between Mangrum and Broomer.
Prior to Mangrum’s homicide, Broomer and Mangrum were arrested on felony drug
charges. At their joint trial, days before the homicide, Broomer testified that the
drugs were Mangrum’s, angering Mangrum and ending their relationship.15
Mangrum began telling people, including on Facebook, that Broomer was a snitch
causing Broomer to be angry in return.16

On April 4, 2015, about an hour before the homicide, Morris saw Broomer at
the McDonald’s in Wilmington. Morris left the McDonald’s to tell Mangrum he had
seen Broomer in Wilmington because he knew that there was bad blood between
them, that Broomer lived in Bear, Delaware, and that there must be a reason Broomer
was in Wilmington.17
On April 4, 2015, at approximately 6:13 p.m., Wilmington Police Officer
Matthew Begany was on patrol, traveling west on 4 th Street toward Monroe Street,
when he heard what he thought were gunshots.18 He turned left, which placed him
southbound on Monroe Street, and observed a stationary blue Ford Focus vehicle at
the end of the alleyway between 2nd and 3rd Streets. Officer Begany saw a man
standing on the passenger side of the vehicle firing a gun.19 As he called for backup,
the officer continued southbound toward the vehicle and the man firing the gun. The
officer then lost sight of the man firing the gun and the Ford Focus began to travel
northbound toward the officer’s car. The Ford Focus then suddenly turned onto a
sidewalk between two rows of houses.20
At that point, Officer Begany observed two black males in the vehicle and
relayed the vehicle’s license plate over the radio. Officer Begany then drove down

to the alleyway where he had observed the man firing the gun to assess if there was
a shooting victim. He observed a man, later identified as Raekwon Mangrum, who
had been shot multiple times and a woman who had been shot once in the leg. The
woman survived. Mangrum died the next day.21
Wilmington Police Officers Brendan Wham and Robert Lynch received
Officer Begany’s call for backup and headed toward the area in their police vehicle.
As they drove toward the scene, Officers Wham and Lynch spotted a blue Ford
Focus with a license plate number matching the one relayed by Officer Begany. The
situation quickly evolved into a high-speed chase as the Ford Focus made its way
onto I-95 North with Officers Wham and Lynch in pursuit, also joined by a host of
other Wilmington Police vehicles.22
The chase continued north across the state line into Pennsylvania, where
Pennsylvania State Police successfully deployed “stop sticks” to puncture the tires
of the Ford Focus. This caused the Ford Focus to slow, eventually coming to a
completed stop. Its occupants abandoned the vehicle and fled on foot. Police
quickly apprehended the driver of the Ford Focus, Michael Broomer, and its
passenger Atiba Mayfield.23

During the chase, Officer Wham observed a handgun being thrown from the
passenger side of the Ford Focus. Police recovered a black CZ .40 caliber semi-
automatic firearm in the area where Officer Wham saw the weapon thrown. Officers
also found a .380 Cobra FS 380 with one spent casing and five rounds of ammunition
in an area along the path of the chase. The police recovered a box of .380
ammunition from under the driver’s seat of the Ford Focus and a spent shell casing
under the passenger side floor mat.24
Both Broomer and Mayfield were charged with Murder in the First Degree,
and various other crimes in connection with the shooting death of Mangrum and the
shooting of the bystander.
Mayfield’s jury trial was held from June 13, 2016 to June 24, 2016. 25 At
Mayfield’s trial, his defense strategy was to claim that this was not a drive-by
shooting. He claimed that he was driven by Broomer to meet with Mangrum
expecting to have a fistfight. There was scuffling. There was not supposed to be
guns. Either Mangrum and/or Morris introduced a gun or guns to the fistfight.
Mangrum and/or Morris started shooting first and that Broomer shot back to protect
Mayfield.26

Mayfield’s defense strategy was not successful. Following his nine-day jury
trial, a jury convicted Mayfield of Murder in the First Degree, two counts of
Possession of a Firearm During the Commission of a Felony (“PFDCF”), Conspiracy
First Degree, and Reckless Endangering First Degree.27 The Possession of a
Firearm by a Person Prohibited (“PFPBB”) charge was severed, and following the
jury’s verdicts of guilty on all the other charges, the State declined to pursue the
PFBPP charge. Mayfield was sentenced on November 4, 2016 to a term of life
imprisonment without probation or parole on the murder charge, plus an additional
five years at Level V on each of the other charges.28
Broomer’s jury trial was held from August 8, 2016 to August 16, 2016.29 At
Broomer’s trial, Broomer did not contest that he was the driver of the blue Ford
Focus and that Mayfield was the shooter that shot and killed Mangrum.30 Broomer’s
defense strategy was premised solely on the intent/state of mind of Broomer and his
co-defendant Mayfield at the time of the shooting.31
Broomer’s defense strategy proved to be partially successful in that Broomer
was not convicted of Murder in the First Degree. Following his seven-day jury trial,
a jury found Broomer guilty of Murder in the Second degree, two counts of PFDCF,

and one count of Reckless Endangering in the First Degree. Broomer was sentenced
to fifteen years of unsuspended Level V time on the Murder in the Second Degree
conviction, plus an additional five years at Level V on each of the other charges.32
PROCEDURAL HISTORY
Following his convictions, Broomer filed a direct appeal to the Delaware
Supreme Court. The Supreme Court affirmed the judgment of the Superior Court in
part, and remanded in part, for the Superior Court to complete a Batson analysis.33
On remand, the Superior Court completed its Batson analysis and found that
Broomer had not carried his burden of proving purposeful discrimination. The
Supreme Court affirmed that decision.34
On October 22, 2018, Broomer filed a pro se Rule 61 motion for
postconviction relief.35 The next day, Broomer’s retained counsel entered his
appearance to represent Broomer in his Rule 61 proceeding. 36 Postconviction
counsel filed an amended Rule 61 motion on March 29, 2019.37
In his first Rule 61 motion, through counsel, Broomer raised 21 allegations of
ineffective assistance of counsel against trial and appellate counsel. Significant here,

included amongst those claims were claims related to the failure of the State to
perform GSR testing of Mangrum’s body and clothing.38
Following a full, careful, and thorough review of the record and submissions,
the Superior Court found that all of Broomer’s claims were without merit.39 On
appeal, the Delaware Supreme Court likewise concluded that Broomer’s first Rule
61 motion was without merit.40
On October 5, 2022, Broomer filed a second Rule 61 motion in which he
raised claims of “newly discovered evidence” and several instances of ineffective
assistance of counsel.41 Like in his first Rule 61 motion, Broomer again raised
claims related to the failure to perform GSR testing of Mangrum’s body and
clothing.42
The Superior Court summarily dismissed Broomer’s second Rule 61 motion
finding that Broomer’s claims regarding the lack of GSR testing were already
adjudicated in his first Rule 61 motion, and all other claims raised were barred as
procedurally defaulted because they were not asserted earlier. 43 On appeal, the

On October 30, 2023, Broomer filed a Rule 35(a) Motion that was treated as
his third Rule 61 motion for postconviction relief.45 On November 6, 2023, the
Superior Court summarily dismissed Broomer’s third Rule 61 motion for failing to
satisfy Rule 61’s procedural requirements for successive Rule 61 motions.46
Broomer also filed a motion for correction of an illegal sentence based on
Erlinger v. United States,47 which was denied by the Superior Court and the denial
was affirmed by the Delaware Supreme Court on appeal.48
On June 18, 2026, Broomer filed the pending Rule 61 motion, his fourth Rule
61 motion. On July 2, 2026, Broomer filed the pending Motion to Transport
Evidence for Defense Forensic Testing seeking to perform GSR testing on
Mangrum’s clothing.
BROOMER’S PENDING MOTIONS
In Broomer’s first pending motion, his fourth Rule 61 motion, Broomer claims
that the testimony of a new witness, Tyrie Burton, who was discovered by
Mayfield’s legal team during briefing on Mayfield’s first Rule 61 motion, satisfies

the actual innocence exception to the procedural bars precluding consideration of
this motion on its merits. In the second pending motion, Broomer has requested
that he be permitted to conduct GSR testing of Mangrum’s clothing, which he claims
that, depending on the results of that testing, may also bolster his justification
defense.
Broomer’s Fourth Rule 61 Motion
This is Broomer’s fourth Rule 61 motion. In second or subsequent Rule 61
postconviction motions, the motion shall be summarily dismissed unless the movant
can satisfy an exception to the procedural bars.49 Here, Broomer claims that a
recently discovered witness satisfies the “actual innocence exception” to the
procedural bars and that he should therefore be allowed to proceed to the merits of
his claim.
The new witness, Tyrie Burton, was located by Broomer’s co-defendant,
Mayfield, during Mayfield’s briefing on his first Rule 61 postconviction motion.
Mr. Burton claimed to have been at the scene of the shooting and his testimony
appeared to bolster Mayfield’s (and Broomer’s) justification/self-defense claims.50
Because the existence of this new witness was raised in Mayfield’s first Rule 61
motion, Mayfield did not have the same pleading requirements preventing
49
Super.Ct.Crim.R. 61(d)(2) & (5); and Rule 61(i).
50
See, State v. Mayfield, 2025 WL 1510143, *17 (Del.Super.), aff’d, 2026 WL 569353 (Del.).
14
consideration of the claim on its merits that Broomer is now facing in this fourth
Rule 61 motion.51
In Mayfield’s first Rule 61 motion, the Superior Court considered the merits
of Mayfield’s claim and thereafter denied Mayfield’s motion finding that the
testimony of the new witness was not persuasive.52 The Delaware Supreme Court
agreed with the Superior Court on Mayfield’s appeal.53
Broomer now raises the existence of this same witness in his pending fourth
Rule 61 motion and claims that the “actual innocence” exception allows him to
overcome the procedural bars preventing consideration of this claim on its merits.
The actual innocence exception allows a defendant to overcome the procedural bars
for proceeding with a second or subsequent Rule 61 motion if the defendant pleads
with particularity that new evidence exists that creates a strong inference that the
movant is actually innocent in fact of the acts underlying the charges of which he
was convicted.54
However, the actual innocence exception cannot be satisfied by new
testimony that only bolsters a defendant’s justification and/or self-defense claims.
New evidence seeking to bolster petitioner’s claim that he was acting in self-defense

15
or that he lacked the requisite intent to be convicted of murder is insufficient to
satisfy the actual innocence pleading requirements.55
To satisfy the actual innocence exception, the new evidence requires more
than innocence of intent, it requires a showing that the new evidence is sufficiently
persuasive to establish that the State convicted the wrong person. That some person
other than the petitioner committed the crime for which he was charged.56
The actual innocence exception is not satisfied when the new evidence only
goes to the lack of the requisite intent to commit the crimes.57 Actual innocence
under Rule 61(d)(2) does not mean that the defendant did not have the necessary
state of mind to be convicted of a particular offense. Proving actual innocence
requires more than innocence of intent; it requires new evidence that a person other
than the petitioner committed the crime.58
Here, Broomer cannot satisfy the actual innocence exception. It was
undisputed that Broomer was the driver of the vehicle, and his co-defendant
55
See, State v. Taylor, 2018 WL 3199537, *7 (Del.Super.)(new evidence proving actual

Mayfield, was the person that shot and killed Mangrum.59 Some person other than
Broomer did not commit the crime for which he was charged. Broomer’s defenses
solely pertained to his intent/state of mind at the time of the shooting and that of his
co-defendant’s.60 The testimony of the new witness seeks only to bolster Broomer’s
justification and/or self-defense claims. Broomer seeks to use the new witness to
bolster Broomer’s defense that he, and his co-defendant, lacked the requisite intent
to be convicted of murder at the time of the shooting.61
Broomer’s “new evidence” claims, proffered to support his argument of
innocence of intent to commit the crimes, fail to meet Rule 61’s actual innocence
exception. Accordingly, Broomer’s fourth Rule 61 motion is procedurally barred
and should be summarily dismissed.
Broomer’s Pending Motion for Forensic GSR Testing
In a companion motion, Broomer has requested that he be permitted to
conduct forensic GSR testing of the victim’s, Mangrum’s, clothing. Broomer claims
that this “new evidence” would further bolster his justification defense, if the testing
proved to be positive.
First, this “evidence” is not new. Broomer knew that GSR testing had not
been performed on Mangrum’s body and clothing at the time of his trial in 2016. In

17
fact, Broomer raised the lack of GSR testing on Mangrum’s body and clothing in
his first Rule 61 motion, which was decided in 202162, and then again in 2022, in his
second Rule 61 motion.63 This “evidence” is not new or recently discovered.
Evidence already raised in a previously adjudicated postconviction motion cannot
constitute newly discovered evidence.64
Any issues regarding GSR testing on Mangrum’s body and clothing are now
procedurally barred. Either the claims were already adjudicated in Broomer’s direct
appeal and/or first Rule 61 motion or are procedurally defaulted because they were
not asserted earlier.65
In Mayfield’s first Rule 61 motion, he requested permission to conduct GSR
testing of Mangrum’s hands. Mayfield’s postconviction counsel requested, and was
granted, permission to conduct the GSR testing requested.66 Mayfield’s
postconviction counsel sought extension after extension of the briefing schedule for
the submission of Mayfield’s first amended Rule 61 motion so that the GSR testing
could be completed.67 In the end, Mayfield’s amended first Rule 61 motion did not

The Superior Court in deciding Mayfield’s first Rule 61 motion surmised that
either the GSR test results were unfavorable or no GSR testing was done. 69 The
Superior Court in denying Mayfield’s Rule 61 motion concluded that in either event
the value of the testing for GSR was uncertain. In other words, the utility of GSR
testing of Mangrum’s hands had not been established.70 The Delaware Supreme
Court agreed on appeal. 71
Broomer now claims that because Mayfield was permitted to conduct GSR
testing in his first Rule 61 motion, Broomer should also be permitted to do so in his
fourth Rule 61 motion. Broomer seeks to conduct GSR testing of Mangrum’s
clothing in this motion. Unlike Mayfield, Broomer did not request to conduct GSR
testing of Mangrum’s body or clothing in his first Rule 61 motion, even though he
knew that the testing had not been performed at the time he filed his first Rule 61
motion in 2019. Broomer did, in fact, raise claims in his first Rule 61 motion related
to the lack of GSR testing of Mangrum’s body and clothing.
This is now Broomer’s fourth Rule 61 motion. The pleading requirements for
proceeding to the merits of a fourth Rule 61 motion are different from those in a first
Rule 61 motion. The fact that Mayfield was permitted to conduct GSR testing in his

first Rule 61 motion has no bearing on Broomer’s entitlement to conduct GSR
testing in his fourth Rule 61 motion.
Broomer cannot satisfy the pleading requirements for proceeding to the merits
of this motion because the lack of GSR testing of Mangrum’s clothing is not new or
recently discovered. Moreover, even if the request to perform GSR testing on the
victim’s clothing was somehow new or recently discovered (which it is not),
Broomer still cannot meet the threshold pleading requirement for proceeding to the
merits of this request.
Broomer claims that this “new evidence”, if the testing results prove to be
positive, would further bolster his justification defense that he and his co-defendant
were acting in self-defense and/or the defense of others at the time of the shooting.
However, as previously discussed, “new” evidence proffered to bolster a
defendant’s defense of justification and/or self-defense does not satisfy the actual
innocence exception to the pleading requirements.
Broomer cannot satisfy the actual innocence exception to the pleading
requirements. It was undisputed that Broomer was the driver and his co-defendant
the shooter in the shooting death of the victim. Broomer does not allege, nor could
he, that someone other than he and his co-defendant committed the underlying acts
in fact for which they were charged. In accordance with the mandates of Rule 61,
20
Broomer’s pending motions should be dismissed as they fail to meet the pleading
requirements for proceeding with this successive Rule 61 motion.
CONCLUSION
For all of the foregoing reasons, Broomer’s fourth Rule 61 motion for
postconviction relief should be SUMMARILY DISMISSED, his motion to conduct
GSR testing of Mangrum’s clothing should be DENIED, and his request for an
evidentiary hearing should be DENIED.
IT IS SO RECOMMENDED.
