A 20-year-old suspect was arrested Saturday in connection with a shooting at a Washington state mall that left five people dead, authorities said.
Police said Arcan Cetin was arrested in Oak Harbor at around 6:30 p.m. while walking down the street — one night after the shooting at Burlington's Cascade Mall sparked a massive search for the suspect.
Island County Sheriff's Lt. Mike Hawley said he had spotted Cetin from a patrol car and recognized him as the suspect.
"I literally hit my brakes, did a quick turn, I jumped out," Hawley said. "We both jumped out with our guns, and he just froze."
Hawley added that Cetin was unarmed, "said nothing" and was arrested without incident.
"He was just kind of zombie-like," Hawley told reporters.
A motive in the shooting is still under investigation, Mount Vernon police Lt. Chris Cammock, part of a multi-agency task force, said at a news conference Saturday night.
When asked whether authorities were considering terrorism as a possible motive, Cammock said he wasn't ruling anything out. However, he cautioned that it was "just too early to tell" and said his response doesn't mean the investigation is going in that direction.
"We're only about a couple hours from taking him into custody, and the next stage right now is to do those interviews and learn more from him, if he's willing to share that with us," Cammock said.
Officials previously said it appears the gunman acted alone and they have no indication it was terrorism.
The tragedy unfolded on Friday night at the Macy's department store.
