San Diego police are investigating what led to the deaths of a family of three found fatally shot in their home on Wednesday morning - a story that arrives with the kind of grim detail that makes you wish the headline were about something else entirely.

The department identified the victims as Amy Voight, 54, David Voight, 56, and the couple's 13-year-old daughter. All three died of gunshot wounds, and investigators found a weapon in the residence, because of course they did.

Gerald Austin, Amy Voight's father, told the San Diego Union-Tribune that his son-in-law had served in the navy as an officer in Iraq and Afghanistan, while his daughter worked as a digital forensic examiner with the Naval Criminal Investigative Service. He said his daughter adored David Voight and that he believed the violence was driven by David Voight's suffering from post-traumatic stress disorder (PTSD).

Mary Austin, Amy Voight's mother, said she had noticed David Voight's symptoms had recently become more severe, and that she and her husband urged their daughter to seek help for the veteran. "You could visibly see there was something really wrong," Mary Austin told Fox 5. "He was fidgety. You could tell."

Gerald Austin said his daughter had sought help for her husband in recent days but they were unable to receive services because they did not have an appointment - allegations the Department of Veterans Affairs denied. The VA said it could not comment on the case, citing privacy concerns, but insisted that "what's being alleged regarding VA services is not accurate."

"All VA healthcare facilities offer same-day mental healthcare to all veterans who need it," said Quinn Slaven, the VA press secretary - a sentence that is either reassuring or the beginning of a very long argument, depending on which side of the phone call you were on.

The couple and their daughter were discovered by a concerned neighbor on Wednesday morning and were pronounced dead at the scene. The county medical examiner's office will conduct autopsies to determine the cause and manner of death, police said in a statement.

Seven out of every 100 veterans will experience PTSD in their lives, according to the VA. The rate is higher among veterans who served in Iraq and Afghanistan, at 29%. Deployment significantly increases the risk of PTSD, according to the VA - which is the sort of statistic that tends to get recited after tragedies rather than before them.
