Officials in Granite Bay, California are reporting that a federal prosecutor fatally shot his wife before turning the gun on himself.

The incident was reported on Sunday.

Placer County Sheriff’s Office investigators say they received a call from the victim’s mother requesting a welfare check after she was unable to get in touch with the couple.
