LOS ANGELES (KABC) -- Murder suspect Christopher Dorner's ex-girlfriend, Ariana Williams, says she fears for her life while Dorner remains on the loose.

Williams filed a restraining order against him following their break up.
"For somebody like Chris, he was the type of person that without him having a badge, without him having that job, title of police officer, I really don't think he would exist without it," Williams said.
Williams dated him five years ago but says Dorner was unraveling even back then. The proud cop and Navy reservist was always on the watch for a possible attack.

"He would leave firearms all over my house," Williams said. "There'd be one, he'd be in the bed and there'd be one by the bed. There'd be one on the kitchen counter. There may be a combat knife or something, maybe I saw, in the bathroom one day or in the kitchen. He said, 'You know, you're always on duty when you're a cop. You don't ever know who is watching you or following you."
