Arcan Cetin is suspected of killing four women and a man Friday night at the Cascade Mall in Burlington, Washington.
Washington state authorities said it’s too early to rule out terrorism or anything else because their investigation is still in the preliminary stages.
Before the suspect’s arrest, an official with the FBI had told reporters there was “no evidence at this time” of a link to terrorism.
‘Kind of zombie-like’
When police confronted the suspect walking down the street near his residence in Oak Harbor, he did not try to run, he just froze and complied, said Lt. Mike Hawley of the Island County Sheriff’s Office.
The suspect, who was not armed at the time of his arrest, said nothing, “kind of zombie-like,” Hawley said.
Cetin immigrated from Turkey and is a legal permanent resident of the United States, authorities said. It’s unclear when he moved to the US.
The shooting stunned the small town as authorities warned residents to stay indoors and be on alert Friday night. The gunman vanished into the night along Interstate 5 after the attack, according to state patrol Sgt. Mark Francis
For much of Saturday, authorities searched the mall for evidence. A blurry surveillance photo of a rifle-toting man inside the mall offered a big lead in the hunt for the shooter.
“The city of Burlington has probably changed forever,” Mayor Steve Sexton said. “This is a senseless act. It was the world knocking on our doorstep, and it came to our little community here.”
