Arcan Cetin, the man charged with killing five people in a shooting at Cascade Mall in Burlington, Wash., last September was found dead Sunday night at the Snohomish County Jail.
The Skagit County Prosecutor's Office said Cetin was discovered hanging in his cell just before 9 p.m. The office could not immediately say why Cetin had been transferred from Skagit County.
Cetin, 20, was charged with five counts of aggravated first-degree murder for the Sept. 23, 2016, killings. The charges alleged Cetin acted with "premeditated intent" when he used a rifle to kill a teenage girl, three women and a man at the Macy's Women's store inside the mall, 65 miles north of Seattle.
