Plaintiffs and appellants Sutton Vance and Thomas O’Shea, the parents of 

decedent Keegan O’Shea (Keegan), initiated this action for general negligence against 

defendants and respondents Apple Valley Unified School District (AVUSD) and bus 

driver Stephanie Casteel (Casteel). They alleged that Keegan, a minor, was involved in a 

sexual relationship with Casteel, an adult, and that Casteel and AVUSD knew about 

Keegan’s history of drug abuse. They further claimed that Casteel and Keegan argued on 

July 2, 2010, and the argument led to Keegan’s drug overdose and death. Defendants 

separately moved for summary judgment pursuant to Code of Civil Procedure section 

437c,

1 attacking the legal element of causation. AVUSD also claimed it was statutorily 

immune. (Ed. Code, § 44808.) Following briefing and argument, the trial court granted 

the motions for summary judgment, finding that plaintiffs failed to establish causation as 

a matter of law.

Plaintiffs appeal, contending the trial court erred in refusing to grant a continuance 

to allow them to present expert testimony and that genuine issues of material fact exist as 

to (1) whether Keegan’s relationship with Casteel caused his death, (2) whether AVUSD 

had notice of Casteel’s relationship with Keegan, and (3) whether AVUSD is immune 

from liability. We affirm.

I. FACTS AND PROCEDURAL HISTORY

Keegan was born on July 21, 1992. Prior to his death in 2010, he had a history of 

drug abuse and drug addiction, including use of heroin, Percocet, OxyContin, and 

 

1

 All further statutory references are to the Code of Civil Procedure unless 

otherwise indicated.

Fentanyl. From December 2009 to June 2010, he was a resident of a drug rehabilitation 

facility in Apple Valley and a student at Granite Hills High School, part of the AVUSD; 

he was transported to and from the school on a school bus driven by Casteel. In June

2010, Keegan completed drug rehabilitation, earned a GED from Granite Hills, and 

returned to Hemet to live with his parents. On July 1, 2010, he wanted to move out of the 

family home after arguing with his father.

In the “late evening hours” of July 1, 2010, Keegan’s mother drove him to a 

restaurant in Devore, where they met Casteel, who transported Keegan to a motel in 

Hesperia. According to Keegan’s brother, Keegan said he went to spend the night at the 

motel with Casteel because he “needed a break” from his parents. On July 2, 2010, 

Keegan spoke with his mother and brother, and his brother offered Keegan a place to 

stay. The next day, Keegan was found deceased in the motel room at approximately 

1:00 p.m. An investigation into his death was initiated.

Chanikarn Changsri, M.D., forensic pathologist and Deputy Medical Examiner 

with the San Bernardino County Sheriff’s Department, Coroner’s Division, autopsied 

Keegan’s body. She opined that his death, within a reasonable medical probability, was

caused by Fentanyl toxicity due to chronic drug abuse. In San Bernardino County, if a 

decedent has a history of chronic drug abuse, the manner of death is regarded as 

“natural.” Dr. Changsri did not regard Keegan’s death as a suicide, given his history and 
4

the conditions of his body at the time of death. It is unknown what led Keegan to ingest 

the drugs that ultimately led to his demise.2

On July 11, 2011, plaintiffs initiated this action against AVUSD and Casteel,

alleging one cause of action for negligence. On February 27, 2013, Casteel moved for 

summary judgment on the ground that she did not cause Keegan’s death. On March 4, 

2013, AVUSD also moved for summary judgment on the grounds there was no evidence 

of a negligent or wrongful act that caused Keegan’s death, and AVUSD is immune from 

liability pursuant to Education Code section 44808. Plaintiffs opposed both motions and 

requested a continuance of the hearing date for the purpose of obtaining an expert 

declaration, if so required by the trial court, that the relationship itself was a contributing 

factor to Keegan’s death. The request was denied on the ground that plaintiffs failed to 

submit an affidavit showing that facts exist to oppose summary judgment; however, the

facts are presently unavailable.

Turning to the merits of the summary judgment motions, the trial court held as 

follows: (1) Keegan’s fatal use of drugs was not related to the alleged relationship with 

Casteel; (2) AVUSD is immune from liability pursuant to Education Code section 44808;

(3) AVUSD had neither actual nor constructive notice of the alleged relationship between 

 

2

 We note plaintiffs’ statement of facts includes references to certain facts (i.e., 

that Casteel was Keegan’s girlfriend; their relationship was known by fellow employees; 

Casteel knew of Keegan’s history of drug abuse and his fragile emotional state; etc.), 

defendants’ evidentiary objections to which were sustained. Plaintiffs have not 

challenged the court’s evidentiary rulings on appeal. As such, we disregard any reference 

to those facts. (§ 437c, subd. (c).)
5

Keegan and Casteel; and (4) any alleged relationship between the two did not cause 

Keegan’s death. Judgment was entered in favor of defendants, and plaintiffs appealed.

II. DISCUSSION

A. Request to Continue Hearing on Motion for Summary Judgment

In opposing summary judgment, plaintiffs asserted that defendants failed to meet 

their burden of proof on the issue that the relationship between Casteel and Keegan 

contributed to Keegan’s drug overdose and death. Plaintiffs further claimed that the issue 

“is one for the jury to decide.” Alternatively, plaintiffs requested a continuance to obtain 

expert testimony “if the Court requires expert testimony . . . that the relationship between 

Keegan . . . and Casteel contributed to the overdose which lead [sic] to the death of 

Keegan.” The trial court denied the request because plaintiffs failed to comply with the 

requirements of section 437c, subdivision (h).

On appeal, plaintiffs assert they “intended and informed the trial court of this 

intent, to have experts testify that the romantic and sexual relationship that [minor 

Keegan] had with an adult 10 years older than him contributed to [his] continue[d] drug 

abuse and eventual death.” They further claim they “informed the trial court that expert 

testimony would be necessary to prove other issues raised in the summary judgment 

motion.” Thus, they fault the trial court for refusing to continue the hearing so they could 

present expert testimony.

“If it appears from the affidavits submitted in opposition to a motion for summary 

judgment or summary adjudication or both that facts essential to justify opposition may 

exist but cannot, for reasons stated, then be presented, the court shall deny the motion, or 
6

order a continuance to permit affidavits to be obtained or discovery to be had or may 

make any other order as may be just.” (§ 437c, subd. (h).) “‘“‘Generally, [the] power to 

determine when a continuance should be granted is within the discretion of the court, and 

there is no right to a continuance as a matter of law. [Citation.]’”’ [Citation.] An 

exception is created by Code of Civil Procedure section 437c, subdivision (h), which 

mandates that the court grant a continuance of a hearing on a motion for summary 

judgment ‘“‘upon a good faith showing by affidavit that a continuance is needed to obtain 

facts essential to justify opposition to the motion.’” [Citations.]’ [Citation.]” (Mahoney 

v. Southland Mental Health Associates Medical Group (1990) 223 Cal.App.3d 167, 170.) 

“Subdivision (h) was added to section 437c ‘“to mitigate summary judgment’s 

harshness”’” as to “‘an opposing party who has not had an opportunity to marshal the 

evidence.’ [Citation.]” (Cooksey v. Alexakis (2004) 123 Cal.App.4th 246, 253.) Thus, a

continuance is “virtually mandated” upon a proper showing. (Bahl v. Bank of America

(2001) 89 Cal.App.4th 389, 395.)

Here, the declaration of counsel in support of plaintiffs’ request for a continuance 

failed to meet the requirements of section 437c, subdivision (h). Counsel did not 

reference any specific evidence that plaintiffs were unable to discover. Rather, he 

explained that no expert declaration had been submitted because defendants had failed to 

sustain their burden of establishing the lack of a triable issue of fact. Counsel added that 

if the trial court believed otherwise, then it should allow further time for plaintiffs to 
7

obtain expert testimony.3 However, “section 437c, subdivision (h) requires more than a 

simple recital that ‘facts essential to justify opposition may exist.’ The affidavit or 

declaration in support of the continuance request must detail the specific facts that would 

show the existence of controverting evidence. [Citations.]” (Lerma v. County of Orange

(2004) 120 Cal.App.4th 709, 715.) Plaintiffs’ counsel’s declaration detailed no facts 

whatsoever. It did not state that an expert had been consulted and that the expert would 

opine on the issue causation. As explained by the Lerma court, “The statute cannot be 

employed as a device to get an automatic continuance by every unprepared party who 

simply files a declaration stating that unspecified essential facts may exist. The party 

seeking the continuance must justify the need, by detailing both the particular essential 

facts that may exist and the specific reasons why they cannot then be presented.” (Id. at 

pp. 715-716; see also Cooksey v. Alexakis, supra, 123 Cal.App.4th at p. 255.) Because 

plaintiffs failed to meet the requirements of section 437c, subdivision (h), the trial court 

was justified in denying their request for a continuance.4

 

3

 As the trial court observed, “Plaintiff has provided no affidavit that indicates 

that the facts necessary to oppose the existence of anything which Plaintiff has not 

already had before him, the Court finds is only a do-over if the Defendant is successful.”

4

 Contrary to plaintiffs’ claim that disclosure of the anticipated expert testimony 

would have required their counsel to breach his attorney work product privilege, courts 

have recognized that under certain circumstances, disclosure of expert witnesses and their 

opinions may be necessary to oppose a motion for summary judgment. (St. Mary 

Medical Center v. Superior Court (1996) 50 Cal.App.4th 1531, 1538-1540.) 

The trial court here made this same point, stating: “[G]oing back to Plaintiff’s

application to disclose or to continue, Plaintiff indicated that he is not obligated to 

disclose experts at this time pursuant to Code of Civil Procedure [section] 2034.010. He 

is correct. However, that does not excuse Plaintiff from supplying expert declarations to

B. Motion for Summary Judgment

1. Standard of Review

Summary judgment is properly granted when all of the papers submitted on the 

motion show there are no triable issues of material fact and the moving party is entitled to 

judgment as a matter of law. (§ 437c, subd. (c).) A defendant is entitled to summary 

judgment if it establishes a complete defense to each of the plaintiff’s causes of action or 

shows that one or more elements of each cause of action cannot be established. (Id., 

subd. (o); Aguilar v. Atlantic Richfield Co. (2001) 25 Cal.4th 826, 849 (Aguilar).) A 

moving defendant bears an initial burden of making a prima facie showing that there are 

no triable issues of material fact. If the defendant meets this burden, the burden shifts to 

the plaintiff to demonstrate the existence of a triable issue of material fact. (§ 437c, subd. 

(p)(2); Aguilar, supra, at pp. 850-851.) From commencement to conclusion, however, 

the moving party defendant generally bears the burden of persuasion that there is no 

triable issue of material fact and that the defendant is entitled to judgment as a matter of 

law. (Id. at p. 850.)

On appeal from the grant of a motion for summary judgment, we independently 

determine whether there are any triable issues of material fact and the moving party is 

entitled to judgment as a matter of law. (Merrill v. Navegar, Inc. (2001) 26 Cal.4th 465, 

 

[footnote continued from previous page]

oppose a summary judgment or summary adjudication. [¶] Nothing in the law requires a 

. . . moving party . . . to wait to file a summary adjudication or summary judgment until 

after the expert designation is made. If that were the case, summary judgments and 

adjudications would always be made on death’s door since the designation of experts 

normally occur later in the proceedings.”

476.) We consider all of the evidence set forth in the moving and opposition papers, 

together with inferences reasonably deducible from the evidence, and we view the 

evidence in the light most favorable to the party opposing the motion. (Aguilar, supra,

25 Cal.4th at p. 843; Ambriz v. Kelegian (2007) 146 Cal.App.4th 1519, 1530.)

2. Wrongful Death

“The wrongful death cause of action was both created and limited by the 

Legislature. ‘“Before 1862 there was no wrongful death action in this state. [Citation.] 

In that year the Legislature, following the philosophy of Lord Campbell’s Act, and to a 

substantial extent its phraseology, created such a cause of action. (Stats. 1862, p. 477.)”’ 

[Citations.] . . . [T]he California Supreme Court examined the history of this cause of 

action and concluded ‘the Legislature intends to occupy the field of recovery for 

wrongful death. For this reason the remedy remains a creature of statute in California 

[citations] regardless of whether a cause of action did or did not exist at common law. . . .

[¶] Because it is a creature of statute, the cause of action for wrongful death “exists only 

so far and in favor of such person as the legislative power may declare.” [Citation.]’ 

[Citation.]” (Bromme v. Pavitt (1992) 5 Cal.App.4th 1487, 1497 (Bromme).)

“A cause of action for the death of a person caused by the wrongful act or neglect 

of another” may be asserted by those persons “who would be entitled to the property of 

the decedent by intestate succession.” (§ 377.60, subd. (a).) Under this section, a 

plaintiff must prove the death was caused by the defendant’s wrongful act or neglect, i.e., 

that the wrongful act was a substantial factor in bringing about the death. (Cf. Bromme, 

supra, 5 Cal.App.4th at pp. 1497-1498.) “Ordinarily, ‘the actor’s negligent conduct is 
10

not a substantial factor in bringing about harm to another if the harm would have been 

sustained even if the actor had not been negligent.’ [Citations.] However, ‘if two forces 

are actively operating, one because of the actor’s negligence, the other not because of any 

misconduct on his part, and each of itself is sufficient to bring about harm to another, the 

actor’s negligence may be found to be a substantial factor in bringing it about.’ 

[Citation.]” (Id. at p. 1498.)

According to the allegations in the complaint, this case involves two forces: 

Keegan’s history of drug dependency and Casteel’s alleged relationship5 with him. 

Therefore, to establish that defendants’ negligence was a substantial factor in causing

Keegan’s death, plaintiffs had to prove defendants’ negligence was of itself sufficient to 

bring about that harm. Defendants moved for summary judgment on the ground that 

plaintiffs were unable to prove causation. The trial court agreed. Plaintiffs contend 

defendants failed to carry their burden of providing evidence sufficient to require a 

reasonable jury to render findings on causation unfavorable to plaintiffs. (Aguilar, supra,

25 Cal.4th at p. 851.) As explained below, defendants succeeded in shifting the burden to 

plaintiffs to raise a triable issue regarding causation.

Defendants seeking summary judgment on a wrongful death claim may submit the 

coroner’s report and testimony to carry their initial burden regarding the cause of death. 

(Majors v. County of Merced (1962) 207 Cal.App.2d 427, 436-437 [defendant’s motion 

for summary judgment on wrongful death claim was properly granted, in view of 

 

5

 As to AVUSD, plaintiffs assert that its knowledge of such relationship and 

failure to take any action against Casteel to end the relationship makes it liable.
11

defendant’s unopposed showing consisting of death certificate and transcript of coroner’s 

inquest]; see also National Life & Accident Ins. Co. v. Edwards (1981) 119 Cal.App.3d 

326, 335 [party successfully opposed summary judgment by pointing to death certificate, 

for purposes of raising triable issue regarding application of death-related term in 

insurance policy].) Here, defendants submitted evidence obtained via various discovery 

methods, including the deposition testimony of San Bernardino County Sheriff’s 

Department Medical Examiner, Dr. Changsri. Dr. Changsri performed the autopsy and 

prepared the report that identified the cause of death. According to Dr. Changsri, Keegan 

died from Fentanyl toxicity due to chronic drug abuse. She ruled out suicide based on 

Keegan’s history of drug abuse and the condition of his body at the time of death. The 

manner of death on his death certificate was listed as “natural.” This showing was 

sufficient to establish that Keegan’s death was not a suicide, absent evidence to the 

contrary, and constitutes evidence regarding the cause of death sufficient to support a 

judgment in favor of defendants. (Bryson v. Manhart (1936) 11 Cal.App.2d 691, 696; 

see Morris v. Noguchi (1983) 141 Cal.App.3d 520, 523, fn. 1.)

Defendants’ showing was sufficient to shift the burden to plaintiffs to raise triable 

issues regarding causation to defeat summary judgment. (See Aguilar, supra, 25 Cal.4th 

at p. 857.) Plaintiffs could perhaps have raised a triable issue by providing “‘competent 

expert testimony.’” (Bromme, supra, 5 Cal.App.4th at p. 1498.) But they failed to do so. 

Rather, plaintiffs relied solely on the conjectural proposition that a romantic/sexual 

relationship between minor Keegan (who had a history of drug abuse) and adult Casteel 

(AVUSD employee) was the legal cause of Keegan’s drug overdose. They speculate 
12

there was an argument between the two about their future as a couple which caused 

Keegan to use drugs to escape reality. They speculate that (1) Casteel said something to 

upset Keegan prior to his death; (2) perhaps she did not leave the hotel room at the time 

she claimed to have done so; and (3) perhaps she told Keegan she wished to end the 

relationship and he responded by self-medicating in order to escape his sadness. 

However, there is no evidence to support any of these conjectural possibilities.

Assuming the existence of a romantic/sexual relationship between Keegan and 

Casteel, we, like the trial court, are left with nothing more than speculative theories about 

what may have happened on the day that Keegan died. However, given the coroner’s 

report, this is not enough. There must be concrete admissible evidence to rebut the fact 

that Keegan died from natural causes. There is none. When the matter remains one of 

pure speculation or conjecture, or the probabilities are at best evenly balanced, “‘it 

becomes the duty of the court to direct a verdict for the defendant.’” (Saelzler v. 

Advanced Group 400 (2001) 25 Cal.4th 763, 775-776 (Saelzler), original italics.)

Saelzler involved a Federal Express employee who sought to deliver a package to 

a resident of a crime-ridden, gang-infested apartment complex. (Saelzler, supra, 25 

Cal.4th at pp. 769, 770.) After attempting to deliver the package, plaintiff was attacked 

by three men who “beat her and attempted to rape her, inflicting serious injuries. After 

assaulting plaintiff, the assailants fled and were never apprehended.” (Id. at p. 769.) The 

owners of the complex knew that criminal activity, including sexual assaults and rapes, 

had occurred frequently on the premises. (Id. at p. 770.) Security patrols were on duty at 

night and the apartment manager used the security personnel to escort her to her vehicle 
13

whenever she left the premises. (Id. at pp. 770-771.) However, the plaintiff “offered no 

evidence showing the identity of her assailants, whether they were gang members, 

whether they trespassed on defendants’ property to assault her, or whether they were 

tenants of the building who were permitted to pass through the security gates.” (Id. at p. 

769.) Instead, plaintiff submitted a declaration from a security expert who opined that the 

attack would not have occurred “‘had there been daytime security and a more concerted 

effort to keep the gates repaired and closed . . . .’” (Id. at p. 771.) For purposes of 

discussion, the Saelzler court assumed duty and breach (id. at pp. 772, 775) and 

considered only whether the evidence established a triable question of causation, i.e.,

whether “defendants’ possible breach of duty [was] a substantial factor in causing 

plaintiff’s injuries.” (Id. at p. 772.)

The Supreme Court refused to accept the plaintiff’s attempts to manufacture 

triable issues via an expert declaration. The Saelzler court found Leslie G. v. Perry & 

Associates (1996) 43 Cal.App.4th 472 (Leslie G.) to be directly on point. In Leslie G., 

summary judgment was granted in favor of defendant on the ground the plaintiff failed to 

establish a sufficient causal connection between defendant’s negligence and the assault. 

(Id. at pp. 478-479.) The court observed: “Since there is no direct evidence that the 

rapist entered or departed through the broken gate (or even that the broken gate was the 

only way he could have entered or departed), [plaintiff] cannot survive summary 

judgment simply because it is possible that he might have entered through the broken 

gate. [Citations.]” (Id. at p. 483.)
14

In both Saelzler and Leslie G., the plaintiff argued that the expert’s opinion 

testimony was sufficient to create a triable issue of fact regarding causation. Both courts 

disagreed: “Where, as here, there is evidence that the assault could have occurred even in 

the absence of the landlord’s negligence, proof of causation cannot be based on mere 

speculation, conjecture and inferences drawn from other inferences to reach a conclusion 

unsupported by any real evidence, or on an expert’s opinion based on inferences, 

speculation and conjecture. [¶] In this case, where there is no factual basis for the 

expert’s opinion or for Leslie’s general assertion of causation, the conclusion is 

unavoidable that summary judgment was properly granted.” (Leslie G., supra, 43 

Cal.App.4th at p. 488, fn. omitted; Saelzler, supra, 25 Cal.4th at p. 775.)

Here, plaintiffs offered nothing more than a mere possibility that defendants’ 

alleged acts, or failure to act, were a substantial factor in causing Keegan’s death. 

Despite having ample opportunity, through pretrial discovery, to gather evidence to 

support their claims, plaintiffs’ evidence merely shows the speculative possibility that 

Keegan’s drug use may have been prevented if he had not been involved with Casteel. 

Plaintiffs’ evidence would be no less speculative because of expert testimony. Moreover, 

we reject their assertion that the minor/adult relationship alone, based on expert 

testimony, may be sufficient “to cause Keegan to resume his drug addiction.” Given the 

coroner’s report, Keegan’s history of drug dependency and strained relationship with his 

father, and the absence of any witness to the events prior to Keegan’s death, the expert 

would have been equally unaware of the facts and thus any opinion regarding causation 

would be too tenuous to create a triable issue whether defendants’ acts, or failure to act, 
15

substantially caused Keegan’s death. (Rinehart v. Boys & Girls Club of Chula Vista

(2005) 133 Cal.App.4th 419, 430-432 [“‘mere possibility of such causation is not 

enough’”]; Thomspon v. Sacramento City Unified School Dist. (2003) 107 Cal.App.4th 

1352, 1371-1373 [no competent proof of causation where expert’s declaration merely 

criticized defendant’s security measures and handling of the matter]. 

Since plaintiffs raised no triable issue of material fact as to causation, defendants 

were entitled to summary judgment. We therefore need not address whether AVUSD had 

notice of the relationship between Keegan and Casteel and whether the immunity 

accorded by Education Code section 44808 also applies in this case.

III. DISPOSITION
