Acting on a telephone tip from a person who was known to police by voice but not by name, police officers searched appellant’s car and found cocaine. At trial, appellant moved to have the cocaine suppressed on the ground that the police lacked probable cause to search. The trial court denied the motion. Appellant then pled guilty to possession with intent to *953 distribute, D.C.Code § 33-541(a)(1). 1 Having preserved the issue pursuant to Super. Ct.Crim. R. 11(a)(2), he argues on appeal that the suppression ruling was erroneous. Because the record developed in the trial court does not contain sufficient indicia of reliability to support a finding of probable cause, we reverse and remand with directions to grant appellant’s motion to suppress.
I.
Viewed in the light most favorable to the government,
In re T.L.L.,
At Sgt. Wilson’s direction, Officer Seth Weston and two other officers arrived at Fourth and L about fifteen minutes later and confirmed the innocent details of the tip, in particular the presence of a car matching the description and a man nearby matching the description. However, the man was not sitting in the car or involved in any suspicious activity when the officers arrived, and when he was unable to produce identification the officers decided not to detain him.
Soon thereafter, one of the officers asked loudly whether anyone owned the car and received no answer. 4 The officers then searched the car. 5 Inside the trunk they found seventeen small bags of cocaine inside a larger bag. They immediately impounded the car.
Subsequently, during an inventory search, a Maryland learner’s permit and District identification card belonging to appellant, the owner of the car, were recovered from the glove compartment. The officers recognized appellant’s picture on the documents as portraying the man to whom they had spoken at the scene.
II.
Since this case involves a tip, we must look to the “totality of the circum
*954
stances” to answer the “practical, commonsense question” whether there was probable cause to believe that the trunk of appellant’s car contained contraband.

See Allen v. United States,
The baseline from which we must start is the Supreme Court’s most recent unanimous pronouncement on anonymous tips in Fourth Amendment searches and seizures,
Florida v. J.L.,
— U.S. -,
J.L. involved a Terry 8 stop based on a completely anonymous telephone tip that a young black man wearing a plaid shirt, standing at a particular bus stop, was carrying a gun. The two officers who responded to the scene confirmed the innocent details of the tip but saw no suspicious activity. Nonetheless, they frisked J.L., a young black man wearing a plaid shirt, and recovered a gun. The Supreme Court held that the gun had to be suppressed because police corroboration of innocent details of this anonymous tip, from someone about whom the police knew nothing, was insufficient to create even the “articulable suspicion” necessary for a Terry stop. The Court put the issue:
Unlike a tip from a known informant whose reputation can be assessed and who can be held responsible if her allegations turn out to be fabricated, an anonymous tip alone seldom demonstrates the informant’s basis of knowledge or veracity. As we have recognized,. however, there are situations in which an anonymous tip, suitably corroborated, exhibits sufficient indicia of reliability to provide reasonable suspicion to make the investigatory stop. The question we here confront is whether the tip pointing to J.L. had those indicia of reliability.
Id.
at 1378 (internal quotation marks and citation omitted). As an example of a case in which there were sufficient indicia of reliability, although it was “borderline,” the Court cited
Alabama v. White,
Of course, accurate prediction of future events has no “talismanic quality” and is only one indicium of reliability.
Gomez v. United States,
Although one might have suspected that the anonymous tipster in
J.L.
had firsthand knowledge of the gun possession, the Supreme Court took pains to point out that the informant “neither explained how he knew about the gun nor supplied any basis for believing he had inside information about J.L.”
J.L., supra,
— U.S. at -,
A more marked distinction between
J.L.
and the ease before us is that the tipster was not in fact a first-tune unknown caller. Perhaps the most telling indicia of reliability can be a tipster’s track record,
i.e.
the number, frequency, content, accuracy (in both innocent and non-innocent detail), and productivity of any past tips.
See, e.g., Jefferson v. United States,
In fact, however, the tipster’s track record was thinly developed in the trial court, and it is well-established that a court may not simply rely on a police officer’s conclusory assertions in deciding whether a search or seizure was justified under the Fourth Amendment, but rather must evaluate the facts underlying those assertions.
See Nance v. United States,
Here there is little more in the record than a conclusory assertion by Sgt. Wilson that the tipster had been reliable in the past. Sgt. Wilson testified that he had personally spoken with the tipster five or six times prior to May 1994 and that the tipster had never given “incorrect” information on those occasions. However, Sgt. Wilson only briefly alludes to the actual nature of those tips, in the following exchange:
Counsel: What kind of information was this that this person was giving you?
Wilson: The person would give me information. A lot of the information that he gave me was information that we already knew. 10
*956 Counsel: I am not sure I understand?
Wilson: Like, if he was saying there were certain houses or apartments that were facilitating the trafficking of narcotics, we would already know about these. If he gave us, say, certain persons coming down there in a certain car, we would already have information already, intelligence already, that this car was, indeed coming to the area.
Counsel: Did — on any of those occasions, prior to May of ’94, had you— had you — had this person ever given you incorrect information?
Wilson: No, sir.
Assuming these examples reer to one or more actual past tips, there is little to be gleaned about their nature from this testimony, or even what it means that the tips were never “incorrect.” Further, we know nothing about the other tips received by Sgt. Wilson, how many tips were drug-related, how many tips were eyewitness, or over how long a period the tips were made. No record was kept of the tipster’s calls, either to the police in general or to Sgt. Wilson in particular, and, at best, the most recent other tip to which Sgt. Wilson testified was made over two years earlier.
We do not challenge the importance of tipsters and other informants in modern police work. In the instant case, it is possible that the complete track record of the tipster actually known to the police could have constituted probable cause to search. The tipster’s eyewitness claim and the minimal evidence of his or her track record presented to the trial court may have been sufficient indicia of reliability to create articulable suspicion for a Terry stop. More extensive on-the-scene surveillance might have provided further corroborative information. However, we are faced with a question of probable cause and, especially given the Supreme Court’s recent guidance in J.L., we must conclude that there was insufficient indicia of reliability in this record to support a finding under that higher standard.
Accordingly, the order appealed from is reversed and the case remanded with directions to grant the motion to suppress and for further proceedings consistent with this opinion. 11
Reversed and remanded.
Notes
. Appellant was given a suspended sentence and two years probation.
. In Sgt. Wilson’s experience, the trunk was not an unusual place for drug dealers to keep their “stashes.”
. The tipster did not give the plate number. There is actually some confusion in the record about whether the tipster referred to a "Dat-sun Z” or a "Nissan 300 ZX”, but no one attempted to clarify this issue at the suppression hearing and neither party attaches any significance to it on appeal.
. The government does not argue that appellant disclaimed ownership of the car and therefore lacks standing to challenge the search, presumably because Officer Weston could not recall whether anyone asked appellant personally whether he owned the car or even whether appellant was still in the area when the officer called out. See
Mills v. United States,
.The officers did not need to use force to access the car because it had an open top and the keys were lying inside on the floor. Of course, the officers could have used "any reasonable means” to open the car if they had probable cause.
Speight v. United States,
. No one challenges that the officers needed probable cause to search the car.
. We delayed decision in this case pending the Supreme Court’s resolution of J.L. See supra note 1.
.
Terry v. Ohio,
. We do not read
J.L.
as necessarily foreclosing the possibility that a technically "anonymous” tip could over have sufficient indicia of reliability to create probable cause.
Compare J.L.,
supra,-U.S. at-,
. In fact, Sgt. Wilson clarified elsewhere in his testimony that the tipster had never before supplied information the police did not already have. However, we cannot accept appellant’s suggestion that this fact alone renders the past tips irrelevant to the reliability determination.
. In directing the grant of the motion, we follow
Nance, supra, 377
A.2d at 390 (reversing and remanding "with directions to suppress the evidence”), and the government does not make a fail-back argument otherwise.
