On May 24, 2016, 59-year-old Daniel Rabideau, a fuel delivery technician for City Fuel, was shot in the head during a routine service call at a home on Currier Drive in Londonderry, New Hampshire. He had spoken on the phone with his wife Carole just minutes earlier. Neighbors reported hearing gunfire shortly after Rabideau’s fuel van arrived; police conducting a welfare check discovered his body.

The homeowner, Richard Verville, described as in his late 60s or early 70s, barricaded himself inside the residence after the shooting. The neighborhood was evacuated and nearby schools were placed on lockdown during an hours-long standoff. Verville later turned the gun on himself and was taken to a Massachusetts hospital with life-threatening injuries; he died the following day. The New Hampshire Attorney General’s office characterized the incident as a murder-suicide and noted Verville had been experiencing significant mental health issues.

Rabideau, married nearly 25 years with five children and eleven grandchildren, was remembered by his wife as a devoted partner who would help anyone. Neighbors said Verville had exhibited paranoia, maintained surveillance around his property, and had ongoing disputes with people in the community; Rabideau’s stepdaughter said some residents were aware of Verville’s problems. Daniel Rabideau was working when he was killed; what questions remain about warning signs or possible interventions?
