A woman accused of fatally shooting her husband Sunday night at their Camas residence told investigators “he attacked me and said he was going to kill me,” court records show.

Stephanie “Sam” Westby, 47, made a first appearance Tuesday morning in Clark County Superior Court on suspicion of first-degree domestic violence murder in the slaying of her husband, 51-year-old Joseph Westby.

Senior Deputy Prosecutor Anna Klein asked Fairgrieve to set Westby’s bail at $750,000, “based on the nature (of the alleged crime) and apparent premeditation.”

Thayer argued that Westby has no criminal history, and there’s no indication she’s a flight risk. He asked she be granted supervised release.
