Washington Mall Shooting: Alleged Shooter Found Dead in Jail

April 17, 2017 4:26 PM EDT

A man accused of killing five people in a shooting at a Washington mall last year was found dead of an apparent suicide.

Arcan Cetin, 20, was awaiting the results of a recently administered mental health evaluation, before he was found dead in his cell in the Snohomish County Jail Sunday evening, the Associated Press reported.

Cetin was charged with killing a teen, three women and one man in a September 2016 shooting at a Macy’s store at the Cascade Mall in Burlington, Wash.

The New York Times reported in September that Cetin had a history of violent behavior and had been charged with domestic violence three times for attacking his stepfather.
