Jason Garcia entered a conditional plea of guilty to possession of methamphetamine with intent to distribute. He now appeals the district court’s denial of his motion to suppress, reiterating on appeal his claim that the police lacked reasonable suspicion or probable cause to frisk him for weapons — and thereby discover the methamphetamine — during their entry into an apartment Mr. Garcia was visiting. We conclude that the district court correctly found that the officers had reasonable suspicion and therefore affirm.
I. BACKGROUND
A. Factual Background
In August 2003, Salt Lake County Sheriffs Detective Tracy Wyant learned from a patrol deputy that an ambulance had responded to a drug overdose at an apartment in Taylorsville, Utah. The deputy told Detective Wyant that he suspected additional drug activity at the apartment and asked Wyant to investigate. The deputy also informed Detective Wyant that one of the individuals involved in the overdose incident was named Dusty Kilgrow.
Detective Wyant was familiar with the apartment complex, having visited it multiple times for narcotics investigations— some of which involved suspects who used or possessed firearms. Detective Wyant performed a records check of the apartment where the overdose had occurred and learned the names of two renters: Dusty Kilgrow (the man who had been involved in the overdose incident) and Lisa Ross. Further investigation revealed that Ms. Ross had an outstanding arrest warrant and that Mr. Kilgrow was an active member of the “Lay Low Crips,” a violent street gang. Detective Wyant knew or learned from the Metro Gang Task Force that in the past the Lay Low Crips had *1061 been involved in the assault-rifle shooting of a West Valley police officer and in the attempted shooting of two Sheriffs Detectives.
Detective Wyant conducted surveillance on the apartment several times, during which he observed short-term traffic in and out of the apartment. On August 18, Detective Wyant and another detective again conducted surveillance on the apartment. In the space of a few minutes, they observed seven individuals coming in and out of the apartment; Wyant identified one of the individuals as Kilgrow. The detectives also saw that two men went out to a car, then returned to the apartment; that several individuals stood out in front of the apartment, apparently conducting countersurveillance; and that the front door was left open for some time. Detective Wyant testified that all this activity was “indicative of narcotics transactions,” although from his surveillance vantage point he did not actually see any such transactions take place.
After observing the above activity, Detective Wyant called to request the assistance of the Metro Gang Task Force. Several members of the Task Force soon arrived, including Sergeant Bill Robertson, and all of the officers then approached the apartment. A woman who had also been approaching the apartment saw the officers, turned around, and began walking away. The officers stopped the woman, who identified herself as Lisa Ross, one of the apartment’s renters. The officers told Ms. Ross that they were there because they had a warrant for her arrest and because they had some concerns about her apartment. While the officers spoke with Ms. Ross, the door to the apartment opened partway and Sergeant Robertson observed several people peering out the door. He recognized one of them from prior gang investigations; that individual was also dressed in a manner consistent with gang membership. This heightened Sergeant Robertson’s concern for the safety of the officers.
The officers further told Ms. Ross that they had seen seven people go into her apartment. She became very emotional and explained that her four-year-old son was in the apartment and that she was unsure who else was inside. She agreed to allow the officers to enter the apartment to check on her son and told them that she thought he was in the back of the apartment. Four or five of the officers, some with weapons drawn, then entered the apartment to do a protective sweep and to look for the child.
When Sergeant Robertson entered into the front room of the apartment, he noticed a small, clear plastic “baggie” on the floor, near the door, containing what appeared to be methamphetamine packaged for sale. A black male dressed in gang-related attire was next to the baggie and the appellant, Mr. Garcia, was about ten feet away. Mr. Garcia was not dressed in gang-related attire, and Sergeant Robertson did not see any tattoos or other indications of gang affiliation on Mr. Garcia. Although Mr. Garcia appeared nervous, he did not make any threatening moves or verbal threats toward the officers.
The officers asked the five or six persons in the front room, including Mr. Garcia, to keep their hands where the officers could see them and to stay where they were. Three officers remained in the front room, and the other officers did a protective sweep of the apartment. They found Ms. Ross’s son in the back bedroom and took him outside to Ms. Ross.
The officers then conducted a pat-down search of the individuals in the front room for weapons. Sergeant Robertson testified at the suppression hearing that the pat-down was conducted because he was *1062 “concerned for the safety of the individuals in the apartment,” including the officers. The presence of what appeared to be methamphetamine on the floor heightened his concern because in Sergeant Robertson’s experience, firearms are often present when narcotics transactions take place. Similarly, the possible gang connection heightened Sergeant Robertson’s concern that guns would be present.
Sergeant Robertson was the officer who frisked Mr. Garcia. During the pat-down, Robertson felt a large bump in Mr. Garcia’s front left pocket. He asked what the object was and Mr. Garcia responded that it was drugs. Sergeant Robertson asked if it was illegal drugs, and Mr. Garcia replied affirmatively. The officers eventually confiscated two bags of methamphetamine and a piece of drug paraphernalia from Mr. Garcia.
B. Procedural Background
Mr. Garcia was charged with one count of possessing methamphetamine with intent to distribute, a violation of 21 U.S.C. § 841(a)(1). He filed a motion to suppress the evidence found during the pat-down. After a hearing, at which both Detective Wyant and Sergeant Robertson testified, the district court denied Mr. Garcia’s motion, concluding that the officers had reasonable suspicion to detain and conduct a pat-down of Mr. Garcia. Mr. Garcia then conditionally pled guilty to possession of methamphetamine with intent to distribute and was sentenced to 120 months in prison. Mr. Garcia timely appealed the denial of his suppression motion. 1
II. DISCUSSION
A. Standard of Review
When reviewing a district court decision on suppression of evidence, we must accept the court’s findings of fact unless, viewing the evidence in the light most favorable to the court’s findings, we conclude the findings were clearly erroneous. Evaluation of the credibility of witnesses, the weight to be given the evidence, and inferences to be drawn from the evidence are for the district court. However, the ultimate determination of whether a search and seizure were reasonable under the Fourth Amendment is subject to de novo review.
United States v. Hernandez,
B. Analysis
“The Supreme Court has identified three general types of encounters between
*1063
citizens and the police: (1) consensual encounters; (2) investigative detentions; and (3) arrests.”
United States v. Hishaw,
In evaluating whether an investigative detention and an attendant search are reasonable under the Fourth Amendment, we apply the principles announced by the Supreme Court in
Terry v. Ohio,
1. Requirement of reasonable suspicion
During an investigative detention, “[police officers are authorized to take reasonable steps necessary to secure their safety and maintain the status quo.”
United States v. Gama-Bastidas,
Although it is of course true that officers “ ‘need not be absolutely certain that [an] individual is armed’ before taking protective measures” such as a pat-down search,
Gama-Bastidas,
In analyzing whether this reasonable suspicion standard is met, we are “to view the officer’s conduct through a filter of common sense and ordinary human experience.”
United States v. Alvarez,
2. Application
In this case, we have no trouble concluding that the facts known to Sergeant Robertson warranted an “articulable and reasonable suspicion” that Mr. Garcia was armed and dangerous, thereby justifying Sergeant Robertson’s pat-down search of Mr. Garcia.
a. Drug transactions
First, we have held that a connection with drug transactions can support a reasonable suspicion that a suspect is armed and dangerous. In
Hishaw,
police officers had learned that a certain apartment was being used to distribute drugs, and Mr. Hishaw was suspected to be the drug dealer.
Numerous other cases lend support to the proposition that an individual’s involvement with drug transactions or distribution can support reasonable suspicion to frisk that individual for weapons. In
Hishaw,
we favorably cited cases from other circuits to this effect.
Id.
at 570-71 (citing
United States v. Perrin,
More recent cases from this and other courts also provide support for our conclusion in
Hishaio. See United States v. Johnson,
In this case, the evidence available to the officers indicated that drug transactions were occurring in the apartment. The original reason for surveilling the apartment was that a drug overdose had taken place there. Detective Wyant had also observed short-term traffic at the apartment, had seen what appeared to be countersurveillance, and had seen other activity that in his experience was consistent with narcotics transactions. Furthermore, one of the apartment’s known renters, Dusty Kilgrow, who had been connected to the drug overdose incident, was a member of a violent street gang that had an extensive history with narcotics. Detective Wyant had identified Kil-grow as one of the seven individuals present at the apartment during the August 18 surveillance, and had told Sergeant Robertson about Kilgrow’s presence in preparation for approaching the apartment. Finally, upon entering the apartment Sergeant Robertson observed a *1066 baggie of what appeared to be methamphetamine lying near the door of the apartment. The methamphetamine appeared to be packaged for sale. It was reasonable for the officers to believe from these facts that there were drug transactions occurring at the apartment.
Moreover, it was reasonable to believe that Mr. Garcia had some connection to or involvement with the drug transactions. As the district court stated,
Mr. Garcia was present in a private home associated with a violent street gang member where illegal drugs were suspected, where (based on the officers’ training and experience) firearms were likely to be, and where illegal drugs were spotted inside. It was reasonable for the officers to connect him with the suspected criminal activity.
Dist. Ct. Op. at 10 (footnote added). The officers could reasonably suspect that everyone present in the front room (where the drugs were found) was involved in the suspected drug transactions.
See United States v. Vite-E spinoza,
b. Gang connection
The apparent gang connection provides additional reason to uphold the district court’s conclusion in this case.
See United States v. Osbourne,
Mr. Garcia emphasizes that, unlike the appellant in
Flett,
he was not dressed in gang attire and that nothing about his appearance indicated to the officers that he was a member of a gang. He also emphasizes that the officers did not recognize him as a gang member and argues that a frisk may not be justified based solely on the company one keeps.
See United States v. Clay,
Mr. Garcia further emphasizes that he was compliant with requests made by the officers, that he made no threatening statements or movements, and that the officers were able to see the hands of everyone in the front room. Although those factors likely helped avoid escalating an already tense situation, we conclude that it did not eliminate the officers’ reasonable suspicion that one or more of the persons present in the front room was armed and dangerous or make the weapons frisk of Mr. Garcia unreasonable.
See Flett,
III. CONCLUSION
For the foregoing reasons, we AFFIRM the denial of Mr. Garcia’s motion to suppress evidence.
Notes
. Mr. Garcia’s notice of appeal incorrectly seeks to appeal "to the Utah Court of Appeals.” Although this technically violates Rule 3(c)(1)(C) of the Federal Rules of Appellate Procedure — which states that a "notice of appeal must ... name the court to which the appeal is taken,” — we have long held that "a defective notice of appeal should not warrant dismissal for want of jurisdiction where the intention to appeal to a certain court of appeals may be reasonably inferred from the notice, and where the defect has not materially misled the appellee.”
Graves v. Gen. Ins. Corp.,
. "[Ijnvestigative detentions ... are Fourth Amendment seizures of limited scope and duration and must be supported by a reasonable suspicion of criminal activity.”
United States v. Davis,
. Mr. Garcia notes in his brief that Sergeant Robertson did not mention the presence of the baggie by the door in either his police report or the probable cause affidavit. However, Mr. Garcia does not appear to challenge the district court's finding that Robertson did actually observe such a baggie upon entering the apartment. In any event, that finding was not clearly erroneous.
. The validity of this proposition is borne out by the experience and training of the officers in this case. Sergeant Robertson testified that in his experience, "when narcotics transactions take place ... a number of times also firearms are present.” Similarly, Detective Wyant’s training taught him that it is "commonplace for weapons, specifically handguns and similar to be present in the distribution and use of narcotics.” And in conducting other narcotics investigations at the very same apartment complex where Mr. Garcia was searched, Detective Wyant had previously encountered suspects who used or possessed firearms.
