Responding officers located the victim in the living room suffering a gunshot wound to the head. He was pronounced dead on the scene.

A preliminary investigation found the victim was home with his wife and son when the incident occurred.

Investigators say the son went upstairs and to get the assault rifle then went into a first-floor bathroom and discharged the weapon one time.
