ALGER, Wash. - A man recently released from jail on drug charges and whose mother calls him "desperately mentally ill" is accused of a shooting spree that left six people dead and two others injured in northwest Washington.

State Department of Corrections officials identified the gunman as Isaac Zamora, 28, who had just served a six-month jail sentence for drug possession in Skagit County. He surrendered to authorities after Tuesday’s deadly spree.
