Lucio P. Madrigal was found guilty of possession of cocaine. He appeals contending the State's evidence should have been suppressed because the police officer did not have an articulable reasonable suspicion of criminal activity necessary to justify an investigatory stop. We affirm.
Facts
Yakima Police Officer Rodney Light was on routine patrol at approximately 6 p.m. on November 19, 1989. A few hundred feet from the Yakima County Courthouse, he observed a "heated argument" between a man, later identified as Mr. Madrigal, and a woman, known to Officer Light as Tia Williamson. He heard the couple yelling more than half a block away. Officer Light concluded Mr. Madrigal's body language was overpowering Ms. Williamson. Believing an assault was about to occur or had occurred or that a domestic quarrel was ensuing, Officer Light stopped his patrol vehicle and approached the couple. Ms. Williamson was crying. The couple continued to yell at each other. Officer Light asked Ms. Williamson if there was a problem. She said no. Officer Light asked Mr. Madrigal for identification and told Ms. Williamson she was free to go. Mr. Madrigal handed over his Washington ID card. Officer Light ran a *281warrant check using a portable radio while he stood with Mr. Madrigal. Within 2 minutes, Officer Light was informed of three outstanding misdemeanor warrants for Mr. Madrigal's arrest.
Officer Light advised Mr. Madrigal he was under arrest, handcuffed him, and conducted a pat-down search. He found two paper bindles in Mr. Madrigal's right front pants pocket. Officer Light recognized that the bindles were folded in a manner consistent with transporting narcotics. He opened the bindles and found a white powdery substance, later determined to be cocaine.
Mr. Madrigal moved to suppress the cocaine contending: (1) there were insufficient facts to justify an investigatory stop; (2) the stop was overly intrusive; and (3) the opening of the bindles was an unreasonable search. The court denied the motion, ruling the search was incident to a lawful arrest because the officer was operating "under the aura of some illegal activity, either an assault, [or] a potential assault." The court found articulable facts to justify the investigative stop. Therefore, it concluded the subsequent warrant check, arrest and search were justified. Mr. Madrigal waived his right to a jury trial. The court found him guilty of possession of cocaine. This appeal followed.
Investigative Stop
Mr. Madrigal contends Officer Light did not have an articulable reasonable suspicion to justify the investigatory stop. Mr. Madrigal argues Officer Light neither observed threatening physical gestures nor heard any threats. Therefore, he concludes, no objective articulable facts suggested actual or potential criminal activity. Relying on State v. Ellwood, 52 Wn. App. 70, 74, 757 P.2d 547 (1988), he argues the tainted evidence should be suppressed.
While findings of the trial court following a suppression hearing are of great significance to a reviewing court, the appellate court makes an independent evaluation of the evidence. State v. Mennegar, 114 Wn.2d 304, 309-10, 787 P.2d 1347 (1990). With regard to credibility issues, defer*282ence is given to the trial court because it has the opportunity to evaluate the demeanor of the witnesses. Mennegar, at 310.
An investigatory stop, although less intrusive than an arrest, is nevertheless a seizure and therefore must be reasonable under the Fourth Amendment and article 1, section 7 of the Washington Constitution. State v. Kennedy, 107 Wn.2d 1, 4, 726 P.2d 445 (1986); State v. Larson, 93 Wn.2d 638, 641, 611 P.2d 771 (1980). Police may make an investigative stop even though there is not probable cause to believe a suspect is involved in criminal activity. Terry v. Ohio, 392 U.S. 1, 25-26, 20 L. Ed. 2d 889, 88 S. Ct. 1868 (1968); State v. Barber, 118 Wn.2d 335, 342-43, 823 P.2d 1068 (1992); State v. Glover, 116 Wn.2d 509, 513, 806 P.2d 760 (1991). When making an investigatory stop, an officer is required by the Fourth Amendment to have a reasonable suspicion, based on objective facts, that an individual is involved in criminal activity. State v. Thompson, 93 Wn.2d 838, 840-41, 613 P.2d 525 (1980). When officers have a reasonable suspicion, they may stop the suspect, identify themselves and ask the person detained for identification and an explanation of his or her activities. State v. Little, 116 Wn.2d 488, 495, 806 P.2d 749 (1991) (relying on State v. White, 97 Wn.2d 92, 105, 640 P.2d 1061 (1982)); State v. Reeb, 63 Wn. App. 678, 680-81, 821 P.2d 84 (1992).
State v. Ellwood, supra, is not controlling. There, the defendant was stopped because of his presence in an area with a history of burglaries. The officer did not observe any suspicious conduct. Ellwood, at 74. Here, Officer Light had a reasonable and articulable suspicion of criminal activity. He saw and heard Mr. Madrigal engaged in a loud altercation with Ms. Williamson. The stop was justified.
Duration of Investigative Stop
Mr. Madrigal contends that even if the initial stop was justified, the evidence seized should be suppressed because the basis for the investigatory stop had ended prior to the warrant check. He submits the request for his identification *283and the warrant check exceeded the scope of Officer Light's investigatory stop. Mr. Madrigal concludes that the warrant check was an unreasonable extension of the initial contact.
After a lawftd investigatory stop, an officer may temporarily detain a suspect pending the results of a police headquarters radio check. State v. Sinclair, 11 Wn. App. 523, 529, 523 P.2d 1209 (1974). Outstanding warrant checks during valid criminal investigatory stops are reasonable routine police procedures. Reeb, at 680-81; State v. Williams, 50 Wn. App. 696, 700, 750 P.2d 278 (1988).
Mr. Madrigal's rebanee on State v. DeArman, 54 Wn. App. 621, 774 P.2d 1247 (1989) is misplaced. In DeArman, an officer observed an automobile stopped in an intersection. Believing it to be disabled, the officer approached. The automobile moved through the intersection; the officer then knew the vehicle was not disabled. Nevertheless, he became "suspicious", approached the vehicle and asked the driver for identification. DeArman, at 623. The court held that once it became apparent the automobile was not disabled, the officer had no reason to proceed with a stop. A generalized suspicion did not justify the stop. DeArman, at 626-27.
The facts here are distinguishable. Officer Light approached not because he was "suspicious", but because Mr. Madrigal was involved in a heated argument with a woman on a public street. Mr. Madrigal's body language was overpowering Ms. Williamson. As the officer approached, the couple continued to yell. An investigative stop was justified. The duration of the warrant check was only about 2 .minutes. It did not unreasonably extend the initial contact.
We affirm.
