David Russo, 43 and a US Navy Chief Petty Officer, was found dead on July 14, 1994, in Riverdale, California. His body was discovered inside his white Dodge Intrepid near the Kings River; an autopsy found a single gunshot wound to the back of the head from a nine-millimeter Beretta.

Investigators noted suspicious circumstances from the start after inconsistent accounts from his wife, Susan Lee Russo. The inquiry uncovered a troubled marriage, Susan’s drug addiction, and an affair with Jason Wesley Andrews. Prosecutors say Susan conspired with Andrews and another accomplice, Bobby Leon Morris, to kill David so she could collect about a million dollars in life insurance. Authorities allege Susan provided the murder weapon from David’s own collection and allowed the men into the home the night he was killed; mistakes during the body’s disposal led to discovery of the crime.

Susan, Jason, and Bobby were arrested within days and later convicted; Susan was sentenced to life in prison. What additional details about David’s last hours or the moves of anyone involved might help clarify what happened that night?
