 Marcos B. was adjudged a ward of the court under Welfare and Institutions 

Code section 602, based on findings he violated Health and Safety Code section 11351 

(possession of narcotics for sale), Health and Safety Code section 11350, subd. (a) 

(possession of narcotics and controlled substances), Health and Safety Code section 

11351.5 (possession of cocaine base for sale), and Health and Safety Code section 11378 

(possession of controlled substances for sale). The case against Marcos relied heavily on 

the observations of Santa Ana Police Officer Corey Slayton, who declined to reveal the 

exact location from which he observed Marcos and two others engaging in what Slayton 

described as drug sales. After an in camera hearing, the court upheld the prosecutor’s 

claim that the location was privileged information under Evidence Code section 1040 (all 

further statutory references are to the Evidence Code) and ruled the location was not 

material information for purposes of section 1042. 

 Marcos asks us to review the transcript of the in camera hearing, to 

ascertain whether the court abused its discretion in determining the location qualified as 

privileged information under section 1040, and argues that even if the claim of privilege 

was properly sustained, the court erred by concluding the officer’s location was not 

material information. We reverse. 

 Our review of the transcript of the in camera hearing demonstrates the 

prosecution provided the court with no information about Slayton’s surveillance location, 

let alone demonstrated why the public interest in preserving the secrecy of this particular 

location might outweigh the necessity of disclosure in the interests of justice. Absent 

such a showing, we conclude the court abused its discretion by upholding the claim of 

privilege. 

 Moreover, even if the claim of privilege had been properly sustained, we 

would conclude the court erred in determining that the location from which Slayton 

observed Marco’s alleged crimes was not material information in the context of this case.

As Marcos points out, Slayton’s observations comprised essentially the entire case 

against him. Although a cache of drugs was retrieved near the scene of Marco’s alleged 

crimes, none were found in his possession, and it is Slayton’s testimony alone which 

links Marcos to the cache and marks him as a participant in the alleged drug sales. Under 

these circumstances, it is crucial that the defense be able to cross-examine Slayton in a 

manner designed to test whether his claimed observations were both reliable and credible. 

Knowledge of Slayton’s claimed location in relation to Marcos at the time of those 

observations was key to that effective cross-examination, and the court’s refusal to allow 

its disclosure consequently denied Marcos a fair trial. 

 

FACTS 

1. The incident

 Slayton testified he was patrolling on foot in the area of 1700 South 

Evergreen in Santa Ana at approximately 6:15 in the evening of July 31, 2011. He was in 

full uniform. While walking in an alley parallel to Evergreen, which runs in a 

north/south direction, he noticed 15-year-old Marcos, another male minor and an adult 

male standing on the west side of the street. 

 Slayton recognized both the other minor and the adult from prior contacts. 

While Slayton watched, a male Hispanic approached the three from the north, removed 

money from his pocket and handed it to the other minor. That minor handed the money 

to the adult male who then handed it to Marcos. Marcos walked across to the east side of 

the street, went to a “white PVC drainage pipe” and removed from it a large plastic 

baggie that contained numerous smaller baggies. He took one of the small baggies out, 

and it appeared to contain a “white sort of substance, crystal-like substance . . . .” Marcos 

then put the large baggie back into the pipe, walked back across the street and handed the 
4

small baggie to the adult male. The adult handed the small baggie to the other minor, 

who handed it to the Hispanic male. The Hispanic male departed. 

 That same series of events, referred to by Slayton as a “narcotics hand-tohand transaction,” was repeated after the trio was approached by a white male. Slayton 

testified the multi-party hand-off procedure for both the money and then the drugs was 

designed to make it more difficult to catch any of the participants in the transaction. 

 During the time Slayton was observing the transactions, he maintained 

radio contact with another officer, who was located to the south of Slayton, and advised 

the other officer about his observations. After completion of the second transaction, both 

Slayton and the other officer approached Marcos and his cohorts from their separate 

locations. Slayton testified he approached Evergreen from the east through a 

“breezeway” between two residential buildings located approximately three houses north 

of where the Marcos and the others were located. Slayton detained the adult and the 

other minor and the other officer detained Marcos. 

 While the other officer stayed with all three suspects, Slayton went over to 

the PVC pipe from which he had seen Marcos remove and replace the plastic bag of 

smaller baggies containing the white substance and retrieved the plastic bag from the 

pipe. The plastic bag held approximately 47 small baggies. Slayton performed reagent 

field tests which showed the contents of the baggies tested positive for heroin and crack 

cocaine. The substances in the baggies were later tested in a laboratory, which revealed 

the baggies contained crack cocaine, heroin and methamphetamine. 

 After Slayton retrieved the bag from the PVC pipe, he searched Marcos and 

found Marcos was in possession of $120 in $20 bills.

2. The claim of privilege

 Defense counsel cross-examined Slayton about his observation of the drug 

transactions. Based upon statements contained in Slayton’s written report, counsel 

established Slayton was walking in an alley parallel to Evergreen when he first saw 

Marcos and the others. Defense counsel then asked Slayton which direction he had been 

walking in the alley. Slayton demurred, explaining he “would rather not say where I was 

coming from.” The prosecutor then objected on the basis the information was privileged 

under Evidence Code section 1040 and requested an “in camera hearing if the court is 

inclined to allow counsel to continue.” 

 Defense counsel objected to the claim of privilege, pointing out “I need to 

know where he was” when Slayton made his observations. Over defense counsel’s 

objection that he was entitled to know the basis of the privilege claim and despite his 

offer to abide by an order not to share any confidential information with his client, the 

court allowed the prosecutor to establish the privilege claim in an in camera hearing 

which excluded both Marcos and his counsel. 

 Following the in camera hearing, the court announced its ruling that 

Slayton’s “surveillance point or post is not material for purposes of section 1042.” The 

court went on to make it clear the defense was “free to cross-examine Officer Slayton . . . 

with respect to all aspects of his observations with the sole exception of the exact location 

from which they were taken.” Specifically, the court noted defense counsel could ask 

Slayton “how far he was, what angle, whether there was an obstructed view or not, you 

know, clear view of the minor’s position. The exact location won’t add anything to that.” 

Defense counsel disagreed, arguing that without information about the exact location 

from which Slayton made his observations, he had no ability to impeach Slayton’s 

testimony. As counsel pointed out, the court’s analysis relied on the assumption Slayton 

was “inherently honest,” which “is certainly not the way it is going to be if the defense 
6

puts people up. This person, if he has got an exact location and he says well, yeah, there 

was no bush in front of me. There was no obstruction to my view. If I don’t know the 

exact location, I can’t impeach him. I can’t go there and take a picture of it and say this 

guy is a liar.” 

 In support of his assertion Slayton’s testimony should not be presumed 

truthful without question, defense counsel focused on Slayton’s claim that he had 

observed “a crystalline white substance” in the baggie handled by Marcos from his 

unknown vantage point, and then suggested it was “not plausible” Slayton could have 

seen the contents of the bag so clearly from “all the way across the street.” He argued 

Slayton’s exact location would prove exculpatory to Marcos if it turned out “it is just so 

far away that there is no way a regular human being could see across the way he said he 

could . . . .” Counsel also pointed out that without knowing Slayton’s location, he had no 

way to challenge the accuracy of Slayton’s estimate of how far away he was while 

observing Marcos. The court rejected defense counsel’s arguments, stating, “you have 

preserved your objections for any type of appeal,” and “your objections are noted.” 

 Defense counsel then asked Slayton “[w]ere there any obstructions to your 

vantage point . . . ?” Slayton answered “yes.” When defense counsel then asked what 

those obstructions were, Slayton explained that identifying the obstructions might reveal 

the location: “whether it was a car, a bush, a tree, a building, a trashcan, a dumpster, 

whatever obstruction I list will give away my location.” The court then revised its earlier 

ruling, stating that “if revealing what [the] obstruction is would reveal the exact location, 

then . . . I am going to exclude that type of questioning. You can still ask how much of 

an obstruction it was.” 

 Defense counsel then moved to strike Slayton’s entire testimony, arguing 

“right now the court is not even allowed to hear testimony from this officer regarding the 

plausibility of his claims. Of course this officer is going to say that he could see what he 
7

said he could see. He is not going to come in here and say I’m a joke and I couldn’t 

actually do it. I can’t cross on that. There is no way that we can even question him at 

this point.” The prosecutor pointed out defense counsel had not yet asked the precise 

question of whether any obstructions impeded Slayton’s “view of the transaction. It has 

always been in terms of vague obstructions here or there.” (Italics added.) The court 

denied defense counsel’s motion to strike. 

 Following a brief recess, the court clarified that defense counsel could ask 

Slayton questions about any obstructions to his view, but Slayton would not be required 

to identify “these specific obstructions that might reveal his location . . . which would not 

be material.” 

 During cross-examination, Slayton estimated he was 35 to 45 feet away 

while he observed the drug transactions, and explained that while he had first observed 

Marcos and the others from the alley, he was no longer in the alley during the period in 

which he was observing the transactions. He also stated he did not observe the 

transactions from the breezeway, but had merely walked through the breezeway on his 

way to Evergreen. Slayton acknowledged he was looking in a “southwesterly direction” 

while observing the transactions, that he was on the east side of Evergreen (the same side 

where the PVC pipe was located) and was observing from a crouched position 

“essentially at ground level.” He would not say how “many houses away” he was, but 

stated there were no obstructions to his view, which spanned 180 degrees. There were 

trees in the area and sometimes Marcos and the others would walk behind them as they 

were moving around, but that did not obstruct Slayton’s view of them. Slayton had 

binoculars with him, but did not use them while observing the drug transactions. He did 

not have to move his feet to get a better viewing position while observing the 

transactions, although he did move his face. 
8

 The court sustained objections to defense counsel’s questions about: (1) 

whether Slayton’s was looking through any “sort of glass substance,” as that might reveal 

whether he was in a building; (2) whether there were any nearby structures which might 

potentially block his view; (3) whether his location “has been obtained and is owned by 

S.A.P.D.”; and (4) whether there were any physical structures that hid his position from 

anyone who might look in his direction. 

 At various points in his questioning of Slayton, defense counsel renewed 

his request to strike Slayton’s testimony. He suggested Slayton’s testimony was 

inherently implausible, because it required one to believe that although Slayton 

acknowledged there were “a good amount of people” out and about on Evergreen during 

the time he was observing the alleged drug transactions, he – a 6’2’’ Caucasian police 

officer in full uniform – had been able to do so from 35 to 45 feet away without anyone 

noticing him. Given that questionable premise, defense counsel argued Slayton’s exact 

location was a fact material to the defense. 

 Defense counsel also pointed out that, as noted in People v. Montgomery

(1988) 205 Cal.App.3d 1011, “the purpose of the defense learning the surveillance 

location was to test the only observation of the sale itself.” He argued that location 

qualified as material evidence here because, as discussed in Montgomery, Slayton’s 

observations constituted the only direct evidence of Marcos’ alleged crimes. The alleged 

purchasers of the drugs were not detained, the transaction was not photographed or 

otherwise memorialized, and Marcos had no drugs in his possession when he was 

detained. The court consistently refused to strike Slayton’s testimony. 

 At the conclusion of the hearing, the court found all allegations of the 

petition to be true, and ordered Marcos committed to 90 days in the Accountability 

Commitment Program, with no early release. Marcos was ordered to pay restitution and 

his eligibility for a driver’s license was delayed for one year. The court also ordered that 
9

Marcos would reside in the custody of his parents, but under the supervision of a 

probation officer. As conditions of probation, Marcos was ordered to submit a DNA 

sample, attend school regularly, participate in family counseling, refrain from possessing 

any alcohol, controlled substances or drug paraphernalia, submit to drug testing and 

searches of his person and vehicle, and observe a curfew. 

DISCUSSION 

1. Determination of Privilege

 Marcos first asks us to review the transcript of the in camera hearing, to 

determine whether the juvenile court abused its discretion by finding that the location of 

Slayton’s observations was privileged information under section 1040. 

 Section 1040 allows a claim of privilege in two circumstances: First, 

information is privileged if “[d]isclosure is forbidden by an act of the Congress of the 

United States or a statute of this state” (§ 1040, subd. (b)(1)); and second, information is 

privileged if “[d]isclosure of the information is against public interest . . . .” (§ 1040, 

subd. (b)(2).) As Marcos points out, the court’s finding of privilege under the latter 

circumstance must be based on a determination that “there is a necessity for preserving 

the confidentiality of the information . . . outweighs the necessity for disclosure in the 

interests of justice . . . .” (§ 1040, subd. (b)(2).) 

 In its brief, the Attorney General acknowledges that the government’s right 

to claim privilege on the basis of public interest is not absolute and that “[o]nce the 

privilege is claimed, the trial court must conduct an in camera hearing to determine if the 

location is privileged,” but then ignores the merits of that issue entirely. Admittedly, 

Marcos’ discussion of the point in his brief is somewhat truncated, but as he properly 
10

points out his ability to argue the merits is restricted by the fact he has no access to the 

sealed transcript of the in camera hearing. The Attorney General has no such excuse. 

 We begin our analysis with the well-established proposition that “‘[t]he 

party claiming privilege carries the burden of showing that the evidence which it seeks to 

suppress is within the terms of the statute.’” (People v. Gionis (1995) 9 Cal.4th 1196, 

1208; D. I. Chadbourne, Inc. v. Superior Court (1964) 60 Cal.2d 723, 729; Tanzola v. De 

Rita (1955) 45 Cal.2d 1, 6.) Moreover, as explained in People v. Superior Court (1971) 

19 Cal.App.3d 522 (Biggs), when it’s the state which seeks to withhold information from 

a criminal defendant, the stakes are particularly high; thus the court must ensure the 

process of assessing the state’s claim of privilege affords the defendant due process. That 

goal is not achieved when the entire process excludes the defendant. “The in camera 

hearing is far too constricted to permit an enlightened determination. Shared only by the 

court and government, it provides no means for assessing the defendant’s claim. It is 

paradoxical to hold a hearing for balancing the conflicting interests of two sides when 

only one is represented. Deprived of the three-way communication habitual to an 

adversary setting, the judge cannot simultaneously perform the tasks of inspecting and 

identifying the material, measuring the government’s claim to withhold it and assessing 

the defendant’s need to get it. The ex parte process places too much confidence in 

judicial prescience and invites error, even unfairness.” (Id. at p. 530, italics omitted.)

 Instead, “[t]he correct procedure in these cases is for the court first to ask 

the defendant to make a prima facie showing for disclosure. [Citations.] If defendant 

does so, the court should then proceed under section 915 and hold an in camera hearing 

attended by the party claiming the privilege . . . . The defendant should be given an 

opportunity to propose questions to be asked at this hearing. The in camera hearing is a 

preliminary inquiry into whether the claim of privilege should be upheld. If the People 

succeed in camera, the adversary process should be utilized, ‘probing the information’s 
11

relevance to the defense, exploring with counsel the availability of other alternatives, and, 

if necessary, hearing testimony voir dire.’ [Citation.] The hearing should conclude with 

the trial court making findings sufficient to enable the appellate court to review its 

decision.” (People v. Montogmery, supra, 205 Cal.App.3d at p. 1021, fns. and italics 

omitted.) 

 That procedure was not adhered to here. Significantly, Marcos was given 

no opportunity to propose questions for the in camera hearing, and the result of that 

hearing was treated as a final, rather than a preliminary, determination that the claim of 

privilege would be sustained. It was only through sheer dint of effort that Marcos’ trial 

counsel was able to keep the issue alive during the course of his cross-examination of 

Slayton. 

 More important, our own review of the transcript of the in camera hearing 

reveals the very problem which the court in Biggs identified as inherent in such 

proceedings; i.e., that “the judge cannot simultaneously perform the tasks of inspecting 

and identifying the material, measuring the government’s claim to withhold it and 

assessing the defendant’s need to get it.” (Biggs, supra, 19 Cal.App.3d. at p. 530.) In 

fact, the court here failed to do any of those things. All that occurred during the in 

camera hearing is that both the prosecutor and Slayton explained to the court, in the most 

generic terms, why police would prefer not to reveal their surveillance locations. They 

did not, however, reveal to the court the location of Slayton’s surveillance or disclose any 

information about it nor did the court ask. This contravenes the whole point of the in 

camera hearing, which is to allow the prosecutor an opportunity to disclose to the court, 

in confidence, sufficient information about the surveillance location to warrant a 

preliminary determination that the state’s assertion of privilege is warranted. Frankly, we 

discern nothing in this transcript that could not have been discussed in the presence of 

Marcos and his counsel. 
12

 Rather than taking the opportunity to give the court some information about 

this particular surveillance location during the in camera hearing, the prosecutor chose 

instead to remind the court, as had already been revealed in testimony, that the area 

where Marcos and his cohorts were apprehended has a “high amount of narcotics 

trafficking activity,” and that the drug dealers engage in “countersurveillance,” so “it is a 

constant battle to stay ahead of the curve in combating crime in the area.” The prosecutor 

also told the court “this is kind of cutting edge, ahead of the game stuff that goes down in 

the Evergreen area.” He did not explain what exactly is cutting edge about it, however. 

Based upon the testimony given in open court, all we know is that there are a lot of drug 

dealers in the area, and they keep a lookout for police. If someone spots a police officer, 

that person will alert others, usually by text message, although sometimes by whistle or 

other audible action. Slayton himself explained to the court that protecting surveillance 

points “is an officer safety issue,” because “just by knowing where I’m hiding, they can 

easily kind of sneak up on us and, you know, do an ambush . . . because we can’t 

necessarily watch our backs all of the time.” 

 Thus, without having revealed any information about the specific 

surveillance location used by Slayton in this case, including whether it was located on 

private property or had been used by police either before or since, the prosecutor simply 

represented to the court that such locations are “confidential information that we would 

like to keep confidential until such time as it is discovered through the normal course of 

business.” That conclusory assertion was apparently deemed sufficient by the court, 

however, because after ascertaining the parameters of the claimed confidentiality, it 

concluded the in camera hearing. 

 Given the paucity of information revealed in this in camera hearing, we 

conclude as a matter of law that the prosecution failed to sustain its burden of proving the 

need to preserve the confidentiality of this surveillance location outweighed the need for 
13

disclosure in the interests of justice. It necessarily follows that the court abused its 

discretion by upholding the claim of privilege. 

 Only if we were to hold that every surveillance location used by a police 

officer, no matter where, and even if it had been used only once and with no anticipation 

it would ever be reused, would qualify as privileged information, could we say the burden 

of establishing privilege had been met here. We cannot do that because the law reflects 

that the justification for finding a surveillance location to be privileged is factual, rather 

than simply a consequence of the desire for confidentiality by the police agency involved. 

In other words, police agencies do not have a unilateral right to simply declare a 

surveillance location privileged. “[O]ne effect of section 1040 is to establish, under 

appropriate circumstances, a ‘“surveillance location privilege”’ in California.” (People 

v. Montgomery, supra, 205 Cal.App.3d at p. 1019, italics added.) 

 If the rule were otherwise, its perniciousness would be evident when we 

consider that once the prosecution’s claim of privilege is sustained, the initial burden 

shifts to the defendant to demonstrate the information is material before the court can 

grant him any relief on the basis it has been withheld. (People v. Lawley (2002) 27 

Cal.4th 102, 159 [“The defendant bears the burden of adducing ‘“‘some evidence’”’ on 

this score”].) Thus, if the prosecution were allowed to simply declare the privilege, 

without making any specific factual showing of need to the court, it could unilaterally put 

defendant at an immediate disadvantage: i.e., the prosecution would be free to withhold 

relevant information about the location of the surveillance from both the defendant and 

the court without consequence, unless the defendant were able to demonstrate, without 

knowing anything specific about it, that revelation of the unknown surveillance location 

“might exonerate” him. (Ibid.) There is more than a whiff of “Catch-22” about that. 

 The factual justifications for declaring a surveillance location privileged are 

outlined in People v. Walker (1991) 230 Cal.App.3d 230: “‘Just as the disclosure of an 
14

informer’s identity may destroy his . . . usefulness in criminal investigations, the 

identification of a hidden observation post will likely destroy the future value of the 

location for police surveillance. The revelation of a surveillance location might also

threaten the safety of police officers using the observation post, or lead to adversity for 

cooperative owners or occupants of the building. Finally, the assurance of nondisclosure 

of a surveillance location may be necessary to encourage property owners or occupants 

to allow the police to make such use of their property.’ Furthermore, in most cases a 

surveillance location and consequently the people who have permitted the use of their 

property deserve more protection than the informant who has mobility as a protection 

against reprisal since ‘a person whose address is revealed has no place to hide.’” (Id. at 

pp. 235-236, italics added.) 

 Here, because the prosecutor revealed no information about the surveillance 

location to the court during the in camera hearing, none of the justifications cited for 

maintaining its secrecy could be inferred. Specifically, the court had no basis to 

determine Slayton’s surveillance location had future value, or that the safety of police 

officers might be compromised by its revelation, because Slayton never represented to 

the court that he or other officers would be expected to use that specific surveillance 

location in the future. By contrast, in Hines v. Superior Court (1988) 203 Cal.App.3d 

1231, the officer “testified that the location was ‘currently used as an ongoing operation 

for investigations’ and that ongoing investigations would be jeopardized by disclosure.” 

(Id. at p. 1233.) And in People v. Montgomery, supra, 205 Cal.App.3d 1011, the officer 

testified “that the location was still being used, and that someone might be hurt or killed 

if he revealed it . . . .” (Id. at p. 1020.) 

 And because no one ever suggested Slayton’s location was inside a 

building or that anyone had given him permission to conduct the surveillance on their 

property, there was no basis for the court to infer that the safety or future cooperation of 
15

local residents might be impaired by its revelation. 

 Moreover, we also note there was no basis to infer the location was special 

in some other way. Neither the prosecutor nor Slayton claimed the police had devoted 

resources to establishing a fixed vantage point for surveilling the neighborhood (such as 

an apartment rented for that purpose, or a fake garbage dumpster situated 

advantageously), or had devised some other surveillance point that might be unexpected

and if revealed would be a significant set-back to future surveillance efforts. For all we 

know, Slayton’s vantage point was not even a permanent location; he might have been 

simply crouching between two parked cars or hiding behind available shrubbery – 

options that would be obvious to any 10 year old playing hide-and-seek. If that were 

true, it would be difficult to conceive of how the need to protect such elementary 

strategies could ever outweigh a defendant’s interest in having the location disclosed. 

 In order to preserve a defendant’s interests in conducting an effective and 

thorough cross-examination of a law enforcement witness who claims to have observed 

the defendant committing the charged crime, the trial court must ensure that a police 

agency’s claim of privilege in connection with a surveillance location is supported by 

evidence sufficient to demonstrate the agency’s need for continued secrecy of that 

particular location outweighs the defendant’s need for it to be disclosed in the normal 

course of a criminal prosecution. Because the prosecutor here offered the court no such 

evidence, the court abused its discretion by sustaining the claim of privilege. 

2. Materiality of the Information 

 Even if the claim of privilege had been properly sustained, Marcos argues 

the court nonetheless erred in ruling the location of Slayton’s surveillance was not 

“material” information in the context of this prosecution. Again, we agree. 

 Section 1042, subdivision (a) provides: “Except where disclosure is 
16

forbidden by an act of Congress of the United States, if a claim of privilege under this 

article by the state or a public entity in this state is sustained in a criminal proceeding, the 

presiding officer shall make such order or finding of fact adverse to the public entity 

bringing the proceeding as is required by law upon any issue in the proceeding to which 

the privileged information is material.” 

 In People v. Lewis (2009) 172 Cal.App.4th 1426, the court reviewed all of 

the published cases addressing whether a surveillance location to which a claim of 

privilege had been sustained qualified as material information and distilled from them the 

following rule: “the location from which the surveillance was performed is not material, 

for the purpose of section 1042’s adverse finding requirement, if the accuracy of the 

testifying officer’s testimony about the surveillance observations is unquestioned, or at 

least is sufficiently corroborated by independent evidence such that there is no realistic 

possibility that disclosing the surveillance location would create a reasonable doubt in 

the minds of a reasonable jury about the officer’s veracity.” (Id. at p. 1438, italics 

added.) 

 For example, in People v. Walker, supra, 230 Cal.App.3d 230, there was 

independent evidence that the officer who observed the drug transaction had transmitted 

the description of the cocaine buyer and his vehicle to another officer, who detained the 

buyer three minutes later and found cocaine in the same pocket where the observing 

officer testified he had seen the buyer conceal it. Moreover, when defendant was later 

arrested, he spontaneously identified the buyer, as well as the buyer’s vehicle and female 

passenger, while denying he had sold them any drugs. All of that independent evidence 

was sufficient to corroborate the accuracy of the observing officer’s testimony and thus to 

demonstrate there was “no realistic possibility that disclosing the surveillance location 

would create a reasonable doubt in the minds of a reasonable jury about the officer’s 

veracity.” (People v. Lewis, supra, 172 Cal.App.4th at p. 1438.) 
17

 Similarly, in In re Sergio M. (1993) 13 Cal.App.4th 809, the observing 

officer’s testimony was also corroborated by evidence that another officer, to whom the 

observing officer had transmitted a description of the buyer in the transaction he 

witnessed, was able to detain the buyer within minutes based on that description and then 

found drugs in the buyer’s possession which were consistent with the observing officer’s 

testimony. 

 And in People v. Haider (1995) 34 Cal.App.4th 661, the buyer in the 

transaction described by the observing officer was then seen by both the observing officer 

and the arresting officer discarding a piece of rock cocaine matching the observing 

officer’s description of the cocaine sold to the buyer by the defendant. Finally, in Lewis

itself, the court noted the accuracy of the observing officer’s testimony that he saw 

appellant sell cocaine to a woman “is corroborated by the fact that [two other officers] 

were able to identify that woman based on Bryant’s description of her appearance, 

location, and direction of travel. Had Bryant been unable to observe the transaction 

between appellant and the woman with sufficient clarity to identify the participants, he 

would not have been able to give an accurate description of the woman to [those other 

officers.]” (People v. Lewis, supra, 172 Cal.App.4th at p. 1440.) 

 The factor common to all of these cases is that other officers were able to 

corroborate the accuracy of the observations made by the officer in the hidden 

surveillance location. The very fact that the second officer was able to act upon a 

description provided by the observing officer and detain the purchaser of drugs only 

minutes after the transaction observed provides compelling independent evidence that the 

alleged crime was, in fact, observed. We have no such evidence here. 

 Although Slayton did testify that he was in radio communication with 

another officer during his observations, he did not describe the specific content of those 

communications, and no record of them was admitted into evidence. The other officer 
18

did not testify. Moreover, because Slayton himself testified that he emerged from his 

hidden location and approached Marcos and his cohorts at the same time as the other 

officer, and that the two officers worked together in detaining and arresting their 

suspects, we have no basis to infer those radio communications provided a sufficiently 

detailed description of the alleged drug transactions and participants to allow the other 

officer to apprehend anyone based solely on the observations communicated by Slayton 

from his surveillance post. Because the two officers worked together, it’s entirely 

possible Slayton simply pointed out the people he wanted to detain to the other officer 

when the two first made visual contact. We simply don’t know. 

 Nor do we have the corroborating evidence found in People v. Garza

(1995) 32 Cal.App.4th 148. There, independent corroboration was provided by the fact 

that when defendant was arrested, he had several packages of cocaine, each weighing 

about one-half gram, in his pocket. The prosecution also offered evidence demonstrating 

that possession of this quantity of cocaine, packaged in such a manner, was sufficient in 

and of itself to establish the defendant’s intention to sell the cocaine, even if the 

observing officer’s description of his activities prior to arrest were disregarded. In those 

circumstances, it seems clear the location from which the officer’s observations were 

made was not material. By contrast to Garza, however, we have no independent 

evidence that Marcos ever had any drugs in his possession. 

 What Marcos did have in his possession is cash; $120, to be exact. While 

that would qualify as independent evidence, and we assume the amount is consistent with 

what would be expected to be found in the possession of a person selling drugs and is 

thus corroborative (People v. Rodrigues (1994) 8 Cal.4th 1060, 1128 [corroborating 

evidence is that which “‘tends to connect the defendant with the crime’”]), we note it is 

also consistent with many other scenarios and thus its corroborative value is slight. 

 Moreover, we conclude the evidence of the drugs retrieved from the PVC 
19

pipe lacks corroborative value. While the presence of the drugs certainly suggests 

someone was dealing drugs in the area, a not surprising revelation given Slayton’s 

characterization of the area as rife with drug dealers, the only evidence that connects 

those drugs to Marcos are the very observations which are challenged here. Thus, unless 

we also presume the accuracy of Slayton’s observations – specifically, his ability to see 

Marcos removing and later replacing the drugs in the PVC pipe with sufficient clarity to 

accurately identify him, their existence does not connect Marcos to a crime any more 

than it would any of the other people Slayton also acknowledged were in the area at the 

time. We cannot, however, assume the accuracy of testimony for purposes of 

determining the extent to which other evidence corroborates it. 

 As explained by our Supreme Court, evidence qualifies as corroborative for 

purposes of validating otherwise questionable testimony “‘“if it does not require 

interpretation and direction from the testimony . . . yet tends to connect the defendant 

with the commission of the offense in such a way as reasonably may satisfy a jury that 

the [witness] is telling the truth.”’” (People v. Szeto (1981) 29 Cal.3d 20, 27 [explaining 

the rule in connection with accomplice testimony].) Corroborating evidence “must, 

without aid from the accomplice’s testimony, tend to connect the defendant with the 

crime.” (People v. McDermott (2002) 28 Cal.4th 946, 986, italics added.) 

 By contrast to this case, the corroborating evidence offered in People v. 

Walker, supra, 230 Cal.App.3d 230, In re Sergio M., supra, 13 Cal.App.4th 809, People 

v. Haider, supra, 34 Cal.App.4th 661, and People v. Lewis, supra, 172 Cal.App.4th 1426, 

provides an independent basis to conclude the observing officer was not only able to view 

a drug transaction, but also able to identify the participants accurately. It thus 

demonstrates the unlikelihood that those defendants would have been able to convince 

anyone the observing officer in their cases did not have a clear view, and consequently 

renders immaterial the information about his precise location. 
20

 Here, the only corroborating evidence we have that does not depend upon 

the accuracy of Slayton’s claimed observations for its significance is the money found in 

Marcos’ possession. As we have already noted, the value of that evidence is slight. It 

does very little to demonstrate that the observations of Marcos Slayton testified to were 

accurate. Consequently, we cannot find that evidence sufficient to support the trial 

court’s determination Slayton’s surveillance location was immaterial; i.e., that “there is 

no realistic possibility that disclosing the surveillance location would create a reasonable 

doubt . . . about the officer’s veracity.” (People v. Lewis, supra, 172 Cal.App.4th at 

p. 1438.) Under these circumstances, we have no choice but to conclude the court erred 

in determining the privileged information was not material in the context of this case. 

DISPOSITION 

 We reverse the order finding the allegations of the petition filed against 

Marcos on August 2, 2011, to be true.
