A Massachusetts police officer who served three decades was killed inside his own home — allegedly by the wife who co-founded an advocacy group for officer mental health — and the suspect was found dead of an apparent self-inflicted gunshot Monday, closing a manhunt but opening harder questions about what broke inside that house and what institutions failed to prevent it.

Kurt Solomon, a 31-year veteran of the Worcester Police Department, was found dead at the Wildwood Avenue residence he co-owned with his wife Karen on Aug. 18 after police responded to a report of a person down at 5:28 a.m. Karen Solomon, 58, was named a suspect and vanished. On Monday, two employees of Fairlawn Rehabilitation Hospital discovered a body in the nearby woods at approximately 12:40 p.m. — a handgun lying nearby. Worcester Police said they believe the deceased is Karen Solomon, pending formal identification.

Worcester Police Chief Paul Saucier called the case a "tragic murder-suicide" and said officials believe Karen Solomon killed herself, according to KRDO. The chief also stated there was no history of domestic abuse between the couple — making the violence all the more confounding. Kurt Solomon's injury involved a sharp object, Saucier said, and his service weapon was never missing from the home. Karen Solomon had been wanted for assault and battery with a dangerous weapon causing serious bodily injury.

Doorbell camera footage released by police shows Karen Solomon walking down a street in a T-shirt, shorts, and flip-flops just minutes after officers responded to the home — walking away from the scene in what looks like eerie calm.

The irony is brutal: Karen Solomon co-founded a group advocating for police officer mental health. She spent years calling attention to the psychological toll of the badge. Whatever crisis consumed this household, the system she championed couldn't reach her — and couldn't save her husband.

Fox News reported that police have disclosed few details about what happened inside the residence, citing the ongoing investigation and domestic violence-related restrictions. Public records show the Solomons co-owned the home; Kurt identified Karen as his wife in a 2016 bankruptcy filing, according to the Associated Press.

The New England Police Benevolent Association remembered Kurt Solomon as "an incredibly dependable officer, colleague and friend," noting that "thirty-one years of service represents an extraordinary commitment to a community and to the profession of law enforcement."

A wake is scheduled for Tuesday and his funeral Wednesday.

An officer who answered the call for three decades didn't get a call for help in the place he should have been safest. The advocate who fought for cops' mental health apparently needed intervention herself. The institutions designed to intervene — didn't. That's the gap that matters, and it's not closing.
