delivered the Opinion of the Court.
Thе prosecution filed this interlocutory appeal pursuant to C.A.R. 4.1 and section 16-12-102(2), 6 C.R.S. (1997), challenging a suppression order of the El Paso County District Court in the prosecution of Rajeem Kasson Canton for possession of a controlled substance (cocaine) with intent to distribute. The trial court concluded that the police officer who detained Canton lacked reasonable suspicion to justify the stop. The trial court, therefore, suppressed the cocaine seized while Canton was detained in the officеr’s car. We reverse the trial court’s ruling and remand the case for furtherproceedings.
I.
On November 1, 1994, Officer Pete Szent-martoni of the Colorado Springs Police Department was on patrol in the area of the Cloud Nine Lounge (“Cloud Nine”) in Colorado Springs, Colorado. The officer was dispatched to Cloud Nine in response to a call for service. That call resulted from an anonymous telephone call to police dispatch reporting that a large group of males were congregated outsidе of Cloud Nine and were possibly involved in drug trafficking.
The officer arrived at Cloud Nine at approximately 3:30 p.m. and observed approximately 10 to 15 males gathered in the front parking lot. With the exception of Canton, all of the males scattered when the officer approached. Unlike the others who were gathered, Canton apparently did not see the officer approach. As the officer got out of his car and drew nearer, he observed a roll of bills in Canton’s right hand. Because Officer Szentmartoni had investigated drug activity at Cloud Nine on previous occasions, he knew of Cloud Nine’s reputation as a site for drug dealing. Thus, as a result of his present observations and his previous experiences with Cloud Nine, the officer suspected that Canton was involved in trafficking drugs.
Aftеr making initial contact with Canton, Officer Szentmartoni patted him down and placed Canton in the backseat of his patrol car. The officer then ran a check for outstanding warrants. 1 While Canton was seated in the back seat, the officer observed Canton fidgeting and reaching into his pockets, as if he were trying to place something in the back seat. When other officers arrived, Officer Szentmartoni removed Canton from the car, handcuffed him, and checked the area where Canton had been sitting. The officer recovered seven small rocks, later determined to be cocaine, from the back seat. The officer then arrested Canton for possession of a controlled substance with intent to distribute. 2
Canton moved to suppress the cocaine pursuant to Crim.P. 41(e), оn the grounds that Officer Szentmartoni lacked reasonable suspicion to justify an investigatory stop of Canton and therefore the cocaine was the product of an unreasonable search and seizure. After a hearing on the motion on September 22, 1997, the trial court made the following factual findings regarding the information known to the officer at the time of the initial contact with Canton: (1) there was an anonymous tip of possible drug dealing in the area of Cloud Nine, (2) Cloud Nine was known as a place where drug deals took place and a large number of males were gathered outside of Cloud Nine, (3) the individuals in contact with Canton or in close proximity to Canton scattered when the officer arrived, and (4) Canton was standing outside of Cloud Nine with a large amount of money in his hand.
The trial сourt concluded that this information was an insufficient basis for suspecting that criminal activity had taken place, was in progress, or was about to occur. Thus, the trial court ruled that Officer Szentmartoni *909 lacked reasonable suspicion to conduct an investigatory stop of the defendant. The trial court granted the defendant’s Motion to Suppress Evidence based on its conclusion that the cocaine was seized as a result of an unconstitutional stop. The prosecution now appeals.
II.
The Fourth Amendment to the United States Constitution and its Colorado counterpart, see Colo. Const. art. II, § 7, protect against unreasonable searches and seizures.
See Minnesota v. Dickerson,
An investigatory stop does not offend the Fourth Amendment provided three criteria are met. First, there must bе an articulable and specific basis in fact for suspecting (i.e., a reasonable suspicion) that criminal activity has taken place, is in progress, or is about to occur. Second, the purpose of the intrusion must be reasonable. Third, the scope and character of the intrusion must be reasonably related to its purpose.
See People v. D.F.,
In this case, the prosecution appeals the trial court’s conclusion that Officer Szent-martoni lacked a reasonable suspicion to justify the initial contact with the defendant. Thus, in this interlocutory appeal we address only the existence of the first criterion for an investigatory stop. The defendant contends that the trial court’s ruling also addressed the final two criteria for an investigatory stop (the purpose and scope of thе intrusion), and therefore this appeal raises these issues. However, a comprehensive reading of the trial court’s ruling leads to the conclusion that the trial court addressed only the issue of whether reasonable suspicion existed to justify stopping the defеndant. The trial court held, in part:
Based on the evidence that has been presented, based on the law that is applicable to warrantless arrests in situations such as this, the Court would determine that reasonable inferences have been shown to justify the initial cоntact with the defendant— I am going to change that. I am going to say there was this initial contact, but it does not rise to the level that crime had been committed by the defendant, that the defendant was involved in criminal, activity, and there was therefore no justification for placing the defendant into the police officer’s vehicle.
Before reaching this conclusion, the trial court discussed
People v. Greer,
*910
In determining whether Officer Szentmartoni was justified in stopping Canton, our analysis focuses on “ ‘whether there were specifiс and articulable facts known to the officer, which taken together with rational inferences from these facts, created a reasonable suspicion of criminal activity to justify the intrusion into the defendant’s personal security.’ ”
Garcia,
In reaching its decision, the trial court below relied heavily upon our decision in
Greer. See Greer,
In this case, Officer Szentmartoni had a clear view of an assembly of a large group of males outside Cloud Nine who scattered when he arrived. The officer also observed the defendant holding a roll of bills in his hand. When considered alone, these observations may not give rise to a reasonable suspicion of criminal activity. These observations, however, took on an added significance in light of the anonymous tip that this group was possibly engaged in drug dealing, the fact that Cloud Nine was known as a site for drug transactions, and the officer’s training and experience in drug enforcement. The rational inferences from these facts provided Officer Szentmartoni with a specific and articulable basis to stop and temporarily detain the defendant for investigatory purposes.
Unlike the situation in
Greer,
the officer in this case had reason to believe that the particular individuals observed were engaged in criminal activity
(ie.,
the anonymous tip that this group was possibly involved in drug trafficking).
Cf. People v. Ratcliff,
“In some circumstances the verification of seemingly innocent details contained in a tip from an anonymous informant can be sufficient to supply the requisite corroboration.”
Garcia,
Furthermore, although a history of criminal activity in a locality does not justify suspension of the constitutional rights of anyone who may subsequently be at that locality,
see People v. Rahming,
The circumstances of this case provided the officer with a speсific and articulable basis in fact to believe that the defendant was engaged or was about to engage in drug trafficking. Accordingly, Officer Szentmar-toni’s decision to stop the defendant for investigatory purposes did not violate the Fourth Amendment.
III.
The trial court’s ruling that Offiсer Szent-martoni lacked a reasonable suspicion to believe illegal activity had occurred or was about to occur is not supported by the record. We therefore reverse the suppression order and remand for further proceedings consistent with this opinion.
Notes
. The prosecution contends that, because Officer Szentmartoni was alone, he did not feel safe leaving Canton outside the patrol car while the officer awaited the results of the warrant search.
. See 18-18-405, 6 C.R.S. (1997).
. When police detain a person without a warrant, the burden of proof is on the prosecution to prove the constitutional validity of the stop and any subsequent search.
See People v. Crow,
. We do not address issues raised by the defendant and not resolved by the trial court in an interlocutory appeal.
See People v. Staton,
. The reaction of these individuals to Officer Szentmartoni's arrival provides another distinction between this case and Greer. In Greer, there was no indication that the two parties were attempting to maintain secrecy or had any fear of being observed. In this case, because the individuals scattered when he approached, Officer Szentmartoni could reasonably believe that they were afraid of being observed (as if they were engaged in illegal activity).
