Nancy Ann Penner, 29, was last seen October 31, 1983, in Paradise, California, where she lived with her boyfriend, Jeff Jeffries, and her two children. She was invited out on Halloween but never arrived; family contact attempts around Thanksgiving failed and a missing persons report was not filed until December 19, 1983.

Jeff Jeffries later told investigators he returned one day to find blood in the house and Nancy missing. A bullet was found lodged in a bathroom cabinet, a detail that prompted investigators to suspect foul play. Nancy’s body has never been found. Her boyfriend moved to Hawaii with the children and died by suicide in 1986. Nancy’s son Omar later described witnessing a traumatic event involving Jeff and his mother, which has kept suspicion on that household.

Investigators have considered that her remains might be in a remote location or a mine shaft in Butte County, but the case remains unresolved. If anyone knew Nancy, lived near Paradise in 1983, or has information about movements around Halloween or the subsequent weeks, please come forward.
