Billy Maxwell Jr. killed his wife Kathy and their two teenage children - Connor and Cameron - before turning a gun on himself Nov. 2.
Documents sent to ABC11 Eyewitness News last week showed how Kathy Maxwell died. Monday, the autopsies for Maxwell and the two children were also released.
They show the entire family was killed by gunshots to the head.
How the family died was of interest to investigators looking into the response time of emergency services. The Cumberland 911 center got a call from the Maxwell home around 6:30 p.m. the evening of the deaths. No one spoke, but there was a sound of gunshots before the call ended. A dispatcher did not send police for more than an hour. Fayetteville police have been looking into why that happened.
Thursday, investigators said a 911 operator violated protocol. A Fayetteville police spokeswoman said the probe was nearing completion but any repercussions for employees would be confidential.
News of the deaths shocked the Fayetteville community, and hundreds gathered at the Snyder Memorial Baptist Church funeral service.
Billy Maxwell was a deacon at the church and he was remembered as a loving father despite the tragedy.
"We have concluded that Billy was suffering with some sort of mental illness. All of us, even those closest to Billy did not know just how sick he was," offered the Rev. John Cook at the funeral.
The children attended Village Christian, where Maxwell was also a coach.
