David Haynes, a 62-year-old emergency medicine physician, and his wife, Lissa Haynes, were tragically killed in their Sunset Cliffs home in San Diego, California, on November 28, 2014. The couple was found shot multiple times in their residence. David, who had a distinguished career in emergency medicine, was well-respected by his peers and patients alike. Lissa, a former nurse, was known for her bright spirit and compassion.
The couple was described as a perfect match, sharing a love for travel and adventure.
The investigation into their deaths revealed that the couple was murdered by their son, Peter Haynes. Peter, who was 23 years old at the time, had a history of mental illness, including schizophrenia. On the night of the murders, Peter returned to his parents' home after Thanksgiving celebrations and shot his mother in the chest. When David heard the gunshot, he went to investigate and was subsequently shot multiple times by his son. Despite being critically injured, David managed to call 911, but both he and Lissa succumbed to their injuries.
Peter Haynes was arrested shortly after the incident, found with the murder weapon in his possession. During the trial, it was revealed that Peter had been self-medicating with illegal drugs and had experienced a psychotic break prior to the murders. His defense attorney argued that Peter's mental illness played a significant role in the tragic events. In June 2017, Peter was sentenced to 100 years to life in prison for the murders of his parents. The judge acknowledged the impact of Peter's mental illness but emphasized the severity of his actions and the lasting trauma inflicted on the family.
The case highlighted the challenges faced by families dealing with mental illness and the devastating consequences that can arise when it is not adequately addressed. The Haynes family, once known for their close-knit bonds and joyful gatherings, now faces an annual reminder of the tragedy that forever changed their lives.
