CONTRA COSTA COUNTY (CBS SF) — A man accused of killing his wife in the wealthy East Bay community of Blackhawk entered a not guilty plea Tuesday after being charged with murder with use of a deadly weapon and elder abuse enhancements, according to the Contra Costa County District Attorney’s Office.

John Tercheria, 69, was arrested Aug. 8, the day after his wife, 69-year-old Linda Marie Tercheria, was found dead from blunt force head trauma at 4:10 p.m. in their 4,000-square-foot home in the 4300 block of Quail Run Lane, according to the Contra Costa County Sheriff’s Office.
