Police in Oak Harbour, Washington arrested the sole suspect in a shooting spree on Friday.
Following a 20-hour manhunt, police arrested Arcan Cetin, 20, a legal Turkish immigrant. Cetin will appear in court on Monday.
On Friday, Cetin killed four women and a man at a Macy’s store at the Cascade Mall in Burlington, a community 100km north of Seattle.
Little is known about the type of weapon he used or his mental health.
The key to his arrest was the identification of his car from CCTV footage.
Authorities were initially looking for a “Hispanic” man. The local sheriff was tipped when the car was seen in Oak Harbour.
He was not armed and did not resist arrest; police said he froze, “zombie-like.”
His motive is unknown.
Authorities are planning to execute a number of search warrants as they try to piece together the puzzle that led to the assault.
Authorities have not ruled out terrorism. But, the FBI has no evidence that suggests ideological or religious motivation. Cetin had a record; in the past, he had been arrested on simple assault charges.
