Kennewick police reported seeing a pistol and evidence of drug activity when they stopped to talk to three men in a car early Friday.
Detectives were patrolling the area of West First Avenue and South Quincy Street just after midnight when they saw a car parked along the road with people inside.
When officers walked to the car, they said a gun was on a seat next to one man, along with evidence of marijuana use and drug packaging.
They discovered warrants for one of the men and that another occupant was a felon.
Joshua W. Verdun, 19, of Kennewick, was arrested on suspicion of being a felon in possession of a gun. Michael P. Wood, 21, of Kennewick, was arrested on two warrants. The third man was released.
Some cocaine and marijuana were seized during their arrests, and officers planned to get a warrant to search the car.
