In Mitchell v. Wisconsin (2019) 588 U.S. 840 (Mitchell), a plurality
opinion from the United States Supreme Court considered the situation
where a police officer comes upon the scene of an automobile accident and
discovers that one of the drivers suspected of driving under the influence of
alcohol (DUI) is unconscious. “[U]nder those circumstances,” the opinion
observed, “the officers’ many responsibilities—such as attending to other
injured drivers or passengers and preventing further accidents—may be
incompatible with the procedures that would be required to obtain a
warrant.” (Id. at p. 843; see id. at pp. 843–844.) Accordingly, Mitchell
articulated a “general rule” that exigent circumstances will “almost always”
permit a blood test without a warrant. (Id. at p. 843.)
In People v. Alvarez (2023) 98 Cal.App.5th 531 (Alvarez), this court
considered the Mitchell general rule in the context of another DUI case that
involved an unconscious suspect-driver. In Alvarez, however, the police
officer did not encounter the suspect-driver at the collision scene, but rather
at the hospital sometime after the accident. We held that the record failed to
support a finding of exigency sufficient to excuse the officer’s failure to obtain
a blood draw warrant. (Alvarez, at pp. 545–546.) In this case, also involving
an unconscious suspect-driver first contacted by police at the hospital several
hours after the accident, we employ similar reasoning to reach a similar
conclusion.
FACTUAL AND PROCEDURAL BACKGROUND
Around midnight, defendant Steven Richard Castro crashed his car
into a vehicle parked in a residential neighborhood in Bloomington, a
community in San Bernardino County. The collision injured the occupant
of the parked vehicle, a rideshare driver waiting for a customer. Hearing
2
the crash, neighbors came outside and restrained Castro, who attempted to
leave the scene.
Shortly thereafter, the California Highway Patrol (CHP) broadcast a
request for available units to respond to the scene of the crash. Eventually,
several CHP officers including Sergeant Bernardino arrived at the scene.
The sergeant later contacted CHP Officer Robert Pope—who was then at the
Arrowhead Regional Medical Center working on an unrelated matter—to
alert him that the driver suspected of causing the Bloomington crash (Castro)
was being transported by ambulance to the medical center to receive
treatment for his injuries.1
During roughly the same time period that Castro was being
transported, Sergeant Bernardino also traveled to the medical center.
On his arrival he spoke with Officer Pope, telling him about the crash.
Bernardino added that Castro had been aggressive with emergency personnel
at the scene and “had to be strapped down to the gurney inside of the
ambulance.”
At approximately 2:30 a.m., Officer Pope went to see Castro in the
emergency room (ER). Castro was sedated and unresponsive. Pope noted
that a “distinct odor of an alcoholic beverage” emanated from his body.
Pope learned from ER personnel that they sedated Castro “due to him being
aggressive with them, yelling at them, and trying to fight them.” They
said he would be unresponsive for another two to three hours.
1 The record does not indicate the exact nature of the injuries, although
they appear to have been minor.
3
Officer Pope spoke by phone with one of the Bloomington neighbors
who witnessed the aftermath of the crash. He also talked with the rideshare
driver-victim, who was being treated at a different hospital. A little over an
hour later, at approximately 3:45 a.m., Pope made the decision to arrest
Castro on suspicion of driving under the influence of alcohol and causing
bodily injury. (See Veh. Code, § 23153.) He said this decision was based on
three factors: (1) the odor of an alcoholic beverage; (2) Castro’s aggressive
behavior with emergency personnel; and (3) the circumstances of the crash,
particularly the fact that Castro collided with a parked car.
At that point, Officer Pope called for a phlebotomist to conduct a blood
draw to determine Castro’s blood alcohol content (BAC).2 He made no
attempt to request a warrant authorizing him to obtain blood from an
unconscious arrestee. Asked why he did not seek a warrant, Pope said it was
“because due to implied consent, I do not need to, if the person is unable to
give consent due to him being unconscious or sedated.” No evidence was
presented as to how long it would have taken to obtain a warrant.
Officer Pope was initially told that the phlebotomist would arrive in
approximately five minutes, but the estimate turned out to be somewhat
optimistic because she did not get to the hospital until approximately
4:00 a.m. and Castro’s blood was not actually drawn until 4:25 a.m. There
was no evidence as to what, if anything, Officer Pope was doing between
2 Officer Pope testified he called “LEMS” to arrange for the blood draw,
but did not further explain the acronym. We infer from context that it is an
organization in San Bernardino County that employs phlebotomists and
contracts with law enforcement agencies to conduct blood draws.
4
3:45 and 4:25 a.m. while he waited.3 The results of the blood test showed a
BAC of 0.193.
Castro brought a motion to suppress evidence pursuant to Penal Code
section 1538.5 in conjunction with his preliminary hearing, seeking to
exclude the blood test results. Relying on the United States Supreme Court
decision in Mitchell, supra, 588 U.S. 840, the magistrate concluded that
exigent circumstances excused Officer Pope from requesting a warrant to
authorize the blood draw. She explained her reasoning: “Every minute that
Officer Pope was there [at the hospital], he was not out on the freeways. So
in my view, I do think that it was appropriate and justified in order to take
blood without a warrant.”
Castro renewed his request to suppress the BAC evidence as part of a
pretrial motion pursuant to Penal Code section 995. (People v. McDonald
(2006) 137 Cal.App.4th 521, 529.) But based on “the whole totality of what
was happening, the chaos, … the demands on the Officer, and the fact that
Mr. Castro was sedated, was unconscious, there had been an accident,” the
court found that “the Officers[’] failure to get a warrant does not … violate
Constitutional rights.” Castro then entered a plea of no contest to a violation
of Vehicle Code section 23153, subdivision (a). This appeal followed. (See
Pen. Code, § 1538.5, subd. (m).)
3 Defense counsel attempted to inquire whether Pope was engaged in
“other type of activity” while he waited for the phlebotomist to arrive. Pope
indicated he did not understand the question. Counsel attempted to clarify,
asking whether Pope was “doing other investigations” or “[w]orking on other
assignments.” The prosecutor objected on relevancy grounds, and the
objection was sustained.

DISCUSSION
No one disputes that a forcible blood draw, as occurred in this case,
implicates the protections of the Fourth Amendment to the United States
Constitution. (U.S. Const., 4th Amend.; see Birchfield v. North Dakota (2016)
579 U.S. 438, 455 (Birchfield) [“taking of a blood sample … is a search”].)
Under general Fourth Amendment principles, a warrantless search or seizure
is presumptively unreasonable unless the government demonstrates the
applicability of a recognized exception to the warrant requirement. (People
v. Laiwa (1983) 34 Cal.3d 711, 725.) Applied in the context of DUI
investigations, it has been clear at least since the United States Supreme
Court decision in Missouri v. McNeely (2013) 569 U.S. 141 (McNeely) that
absent an applicable exception, “the Fourth Amendment requires a warrant
for a blood draw.” (Alvarez, supra, 98 Cal.App.5th at p. 546.)
One recognized exception to the warrant requirement is when exigent
circumstances make it impossible or impractical for law enforcement officers
to take the time that would be required to obtain a warrant. (People v.
Ovieda (2019) 7 Cal.5th 1034, 1041.) And it has long been accepted that the
evanescent nature of alcohol in the blood as evidence of a DUI violation can
contribute to a finding of an emergency that would justify a warrantless blood
draw. (See, e.g., Schmerber v. California (1966) 384 U.S. 757, 770 [“the
percentage of alcohol in the blood begins to diminish shortly after drinking
stops, as the body functions to eliminate it from the system”].) In McNeely,
the Court again acknowledged this physiological reality (McNeely, supra,
569 U.S. at p. 152), but nonetheless rejected the government’s argument
that it justified a per se exigent circumstances exception to the warrant
requirement: “In short, while the natural dissipation of alcohol in the blood
may support a finding of exigency in a specific case, … it does not do so
6
categorically. Whether a warrantless blood test of a drunk-driving suspect is
reasonable must be determined case by case based on the totality of the
circumstances.” (Id. at p. 156; see also id. at p. 152 [refusing to “depart from
careful case-by-case assessment of exigency and adopt the categorical rule
proposed by the State”].)
Three years after McNeely, the United States Supreme Court was
asked to create a different automatic exception to the warrant requirement
for DUI breath tests and blood draws based on the search-incident-to-arrest
concept. (Birchfield v. North Dakota (2016) 579 U.S. 438.) The Court
accepted the argument as to breath tests, but balked at extending this new
rule to blood tests: “Blood tests are significantly more intrusive, and their
reasonableness must be judged in light of the availability of the less invasive
alternative of a breath test. Respondents have offered no satisfactory
justification for demanding the more intrusive alternative without a
warrant.” (Id. at p. 474.) Significantly for our purposes, the Court
commented on the situation we confront of an unconscious suspect-driver,
noting that it will generally require a warrant:
“It is true that a blood test, unlike a breath test, may be
administered to a person who is unconscious (perhaps as
a result of a crash) or who is unable to do what is needed
to take a breath test due to profound intoxication or
injuries. But we have no reason to believe that such
situations are common in drunk-driving arrests, and when
they arise, the police may apply for a warrant if need be.”
(Id. at p. 475.)
Another three years later, the United States Supreme Court once again
considered the exigent circumstances exception in the context of a DUI blood
draw, focusing specifically on the situation where the suspect-driver is
unconscious. (Mitchell, supra, 588 U.S. 840.) Although the Court’s plurality
7
opinion commented that “the exigent-circumstances rule [will] almost always
permit[] a blood test without a warrant” in this situation (id. at p. 843, italics
added), it does not do so automatically or without further inquiry. Rather,
“exigency exists when (1) BAC evidence is dissipating and (2) some other
factor creates pressing health, safety, or law enforcement needs that would
take priority over a warrant application.” (Id. at p. 854; see also People v.
Nault (2021) 72 Cal.App.5th 1144, 1148.) With respect to the second factor,
Mitchell acknowledged that the defendant should be given the opportunity to
show either (a) “his blood would not have been drawn if police had not been
seeking BAC information,” or (b) “police could not have reasonably judged
that a warrant application would interfere with other pressing needs or
duties.” (Mitchell, at p. 857.)
Our decision in Alvarez, supra, 98 Cal.App.5th 531 also involved a
blood draw from an unconscious suspect-driver and makes clear that while
many such situations will involve exigent circumstances, not every case will
excuse the failure to obtain a warrant. In Alvarez, police arrived at the scene
of a two-car collision and discovered the deceased victim, a 15-year-old minor
from the same vehicle, and a third person—the defendant—who admitted to
driving the second vehicle. The defendant seemed shaken but uninjured, and
did not show overt symptoms of intoxication. (Id. at p. 537.) While police
continued their investigation at the scene, the defendant and the minor were
transported to a local hospital by emergency medical personnel. (Ibid.)
One of the officers, Officer Yost, finished his work at the accident scene
and drove to the hospital, where he first contacted the defendant 75 minutes
after the accident and smelled the odor of an alcoholic beverage emanating
from him. (Alvarez, supra, 98 Cal.App.5th at p. 538.) About 15 minutes
later, Yost used a preliminary alcohol screening (PAS) device in an attempt
8
to obtain an analyzable breath sample. The defendant was unable or
unwilling to provide a breath sample sufficient for the PAS device to operate
automatically. But Yost was able to capture two “manual trap” samples,
which he testified would typically yield a lower result than the automatic
method. The manual samples measured a BAC of 0.037 and 0.039. (Ibid.)
At that point, Officer Yost decided to request a blood sample, but the
defendant had become unresponsive.4 So Yost called to request a forensic
blood draw, making no attempt to obtain a warrant. (Alvarez, supra, 98
Cal.App.5th at pp. 539, 541.) He later testified he was concerned that if
he took the time to obtain a warrant, hospital personnel might take the
defendant away for treatment in a different part of the hospital. (Id. at
pp. 540–541.) The phlebotomist arrived in about 30 minutes and drew the
blood while the defendant remained unresponsive. The test revealed a BAC
of 0.05. (Id. at p. 539.)
Relying primarily on Mitchell, the People argued that the
circumstances in Alvarez demonstrated sufficient exigency to excuse the
officer’s failure to seek a warrant before the blood draw. We disagreed.
We began our analysis of the exigency issue by observing that Mitchell
“did not reverse McNeely’s rule that officers need a blood-draw warrant if one
is practical to obtain.” (Alvarez, supra, 98 Cal.App.5th at p. 544.) We noted
that Mitchell’s discussion of exigency must be understood in the context of
the facts of that case—the more typical situation where the suspect-driver is
injured in the accident and ultimately loses consciousness (at the scene or on
4 The defendant was lying on a hospital bed with his eyes closed. He
did not respond to the officer, hospital personnel, or anyone else. The officer
testified he “could not tell whether [the defendant] was asleep, unconscious,
or just ignoring him.” (Alvarez, supra, 98 Cal.App.5th at p. 539.)
9
the way to the hospital) before police can conduct a normal investigation.
As the Mitchell court observed, officers at the accident scene may have
insufficient time or resources to attend to the injured, control affected traffic,
investigate the cause of the accident, and obtain a warrant. (Mitchell, supra,
588 U.S. at p. 856.) In addition, necessary medical treatment for the suspect-
driver might interfere with an evidentiary blood draw. (Id. at p. 855.)
In Alvarez, however, as is true in this case, the defendant’s
unresponsiveness “did not motivate his transport to the hospital.” (Alvarez,
supra, 98 Cal.App.5th at p. 545.) Rather, he was taken to a medical facility
more as a precaution. (Id. at p. 544.) The defendant in Alvarez appears to
have become unresponsive gradually over a 90 minute time period after the
accident. (Id. at p. 545.) There was nothing in the record to indicate he
required any emergency treatment as a result. (Id. at p. 539.) In this case,
Castro’s unresponsiveness was apparently unrelated to any physical effects of
the collision. Instead, he became combative with emergency room personnel
at the hospital and had to be sedated hours after the accident. Again, he
received no emergency treatment.
Our focus in Alvarez on whether the defendant’s unconsciousness
motivated transport to the hospital stems, at least in part, from an
assumption that appears to permeate the discussion of exigency in Mitchell.
At the outset of the plurality opinion, Justice Alito posits what he considers
a paradigmatic situation where “police officers most frequently come upon
unconscious drivers when they report to the scene of an accident, and under
those circumstances, the officers’ many responsibilities—such as attending to
other injured drivers or passengers and preventing further accidents—may
be incompatible with the procedures that would be required to obtain a
warrant.” (Mitchell, supra, 588 U.S. at pp. 843–844.) This hypothetical
10
scenario underlies much of the exigency discussion in the opinion. It portrays
harried officers conducting “triage” at an accident scene, balancing a host of
“rival priorities” that will be all the more impossible if they are required to
obtain a blood draw warrant. (Id. at p. 856.) According to the opinion, “[t]his
is just the kind of scenario for which the exigency rule was born—just the
kind of grim dilemma it lives to dissolve,” and justifies the “general rule” that
“when a driver is unconscious, … a warrant is not needed.” (Id. at p. 856; see
id. at p. 844.) But when the suspect-driver falls unconscious sometime later,
away from the scene, exigency is not so apparent.
Indeed, neither this case nor Alvarez fits the Mitchell paradigm. In
Alvarez, although Officer Yost initially spent some time at the accident scene,
it was only after he finished his responsibilities there that he drove to the
hospital to contact the defendant. In this case, Officer Pope was never at the
scene of the collision. Whatever “urgent tasks” and “pressing matters”
confronted officers and emergency personnel at those locations, they were
not a concern for Officers Yost and Pope at the point in time they decided to
request a blood draw.
Mitchell itself acknowledges there may be situations where a blood
draw warrant for an unresponsive suspect-driver is required because “police
could not have reasonably judged that a warrant application would interfere
with other pressing needs or duties.” (Michell, supra, 588 U.S. at p. 857.) In
Alvarez, we located nothing in the record to support a conclusion that a delay
in getting a warrant would have diverted Officer Yost from any aspect of his
investigation. (Alvarez, supra, 98 Cal.App.5th at p. 545.) We reach a similar
conclusion here.
In terms of how seeking a warrant might have interfered with other
responsibilities, we agree with the People that the critical period of time is
11
from 3:45 a.m., when Officer Pope decided to arrest Castro, and 4:25 a.m.,
when Castro’s blood was drawn. At 3:45 a.m., Pope was not at the scene of
the collision, where Mitchell teaches he might have been distracted by other
accident-related tasks. He was at the hospital, where he had been the entire
evening, and the prosecution offered no evidence as to what Pope was doing
during this time period.5 In response to a general inquiry by defense counsel,
Pope claimed he could not remember what he was doing. When counsel tried
to ask him whether he was working on other assignments or investigations,
the prosecutor successfully objected that the question was irrelevant.
The Attorney General seeks to distinguish Alvarez “because [Castro]
was transported to the hospital for injuries and sedated from the moment
Officer Pope first tried to contact him,” whereas the defendant in Alvarez
spoke to law enforcement and was administered field sobriety tests before
becoming unconscious. But these are distinctions without a difference and
played no role in our Alvarez analysis with regard to whether obtaining a
warrant would have diverted the officer from other more pressing duties.
In Alvarez, we found it significant that Officer Yost “ ‘was[n’t] thinking [he]
should get a warrant.’ ” (98 Cal.App.5th at p. 545.) Similarly here, Pope
simply did not believe he needed to obtain a warrant for an unconscious
suspect-driver. In neither case was the officer balancing the time it would
take to get a warrant against other pressing investigatory duties.
5 The Attorney General asks us to assume that “[a]t a minimum,
securing a warrant would have required Officer Pope—the only investigating
officer—to pause his DUI investigation.” We cannot indulge this assumption
absent some evidence showing that he was actually performing investigative
tasks while he waited for the blood draw. So far as this record shows, Pope
had completed his investigation with the exception of obtaining an
evidentiary blood sample.
12
Ultimately, Mitchell’s references to “rival priorities,” “more pressing
needs,” and “other pressing duties” of police officers (588 U.S. at p. 856; see
id. at pp. 840, 851), must be understood in the context of the opinion’s focus
on an officer responding to the natural chaos that pervades the scene
of automobile accident. And this focus helps explain the flaw in the
magistrate’s reasoning when she suggested that a finding of exigency could
be based on the fact that “[e]very minute that Officer Pope was there [at
the hospital], he was not out on the freeways.” Accepting that theory, the
exigency exception would swallow the warrant rule because the time an
officer spends obtaining a warrant could always be used for other police
duties. Yet we must remember that obtaining warrants before conducting
searches and seizures is a crucial part of a police officer’s duties, not a
distraction from them, and Mitchell does not suggest otherwise. Rather,
Mitchell only observes that traffic accidents, by their very nature, often
create competing demands on an officer’s time, which will be especially
relevant in establishing exigent circumstances.
Consistent with Alvarez, we conclude that the record in this case fails
to support the trial court’s finding of exigency so as to excuse the failure to
obtain a warrant. (98 Cal.App.5th at p. 546.)

DISPOSITION
The judgment is reversed. The matter is remanded to the superior
court with instructions to (1) vacate the order denying Castro’s suppression
motion and enter a new order granting it; (2) permit Castro to withdraw his
guilty plea by appropriate motion within 30 days after this opinion becomes
final; and (3) if he does so, determine whether the People intend to retry the
case.
