David Haynes, a 62-year-old emergency medicine physician, and his wife Lissa Haynes were found shot multiple times in their Sunset Cliffs home in San Diego on November 28, 2014. David was described as a respected physician and Lissa as a former nurse with a bright spirit; the couple shared a love for travel and were said to be a perfect match.

Investigators say their 23-year-old son, Peter Haynes, returned to the family home after Thanksgiving celebrations and shot Lissa in the chest. When David went to investigate the gunshot, he was shot multiple times. David managed to call 911 while critically injured, but both parents later died. Peter was arrested at the scene and was found in possession of the murder weapon; reports indicate he had a history of mental illness, including schizophrenia, and had been self-medicating with illegal drugs prior to the incident.

The killings left the family devastated and raised difficult questions about managing severe mental illness in families. If anyone knew the Hayneses or has information about that night, please share what might help clarify what happened.
