SEATTLE (AP) — Police say a man arrested after firing 15 shots at a uniformed officer in Renton this week is believed to have previously fired at a state trooper. Frankie Taijon Robertson was arrested after a car he was riding in fled the shooting in Renton on Tuesday. No one was hurt, but Renton police said surveillance video showed the 24-year-old Kirkland, Washington, man firing at a patrol car stopped at an intersection. According to investigators, Robertson was also suspected of shooting at a Washington State Patrol trooper’s patrol car on the northbound Interstate 5 ramp onto Interstate 405 in March. It was not immediately clear if Robertson had obtained a lawyer; he was being held on $500,000 bail.
