An argument that started Monday night at a rest stop on Interstate 5 ended in front of a Federal Way Safeway after shots were fired by a suspect who’s now in police custody.

Federal Way police responded to assist Washington State Patrol officers on a call reporting shots fired at the scales on northbound I-5 a couple miles from the State Route 18 on-ramp. No injuries were reported, and officers were able to “ping” the suspect’s cell phone and make contact. The suspect told police he was “going to go to the Safeway.”

Police arrived at the Safeway at 1207 S. 320th St., Federal Way, and Washington State Patrol officers apprehended the suspect without incident.

Further details are unavailable at this time. A spokesman for the Washington State Patrol said detectives could not comment on the case as it’s ongoing.
