Seattle police arrested multiple teens and seized a cache of weapons last week. Officers knew the car, a Chevrolet Malibu, because it was involved in a September 20 shooting. Witnesses reported a group of teens exchanging guns in the area. They subsequently recovered a submachine gun with a 30-round magazine, a handgun with an auto switch and extended magazine, a handgun with an auto switch and 50-round drum magazine, and a handgun with a 30-round drum magazine. Police booked three of the suspects into juvenile detention at the Judge Patricia H. Clark Children and Family Justice Center.
