UPDATE: Blackhawk man arrested in connection with wife's death

69-year-old victim identified; cause of death listed as head trauma

A Blackhawk man has been arrested on suspicion of murder for the death of his wife, who was found in their home Sunday afternoon, according to a Contra Costa County Sheriff's Office spokesman.

John Tercheria, 69, was booked into the Martinez Detention Facility early Monday morning with bail set at $1 million, according to sheriff's office spokesman Jimmy Lee. John Tercheria was released from jail custody around 1 p.m. Monday after posting bail, Lee said.

The arrest came after deputies responded to a suspicious circumstance report and discovered Linda Marie Tercheria, 69, unresponsive in the couple's home on the 4300 block of Quail Run Lane in Blackhawk around 4:10 p.m. Sunday, according to Lee.

Linda Marie Tercheria was later pronounced dead, with her cause of death determined to be blunt force head injury, Lee said.

Additional details about the potential motive, the circumstances of John Tercheria's arrest and other aspects of the case were not released as of Monday afternoon.

The sheriff's office is seeking information about the incident, asking anyone with details to contact its investigation division at 313-2600. Tips, anonymous or otherwise, can be emailed to or left via voicemail at 866-846-3592.
