A 31-year-old man charged with murder in Lebanon told police the victim had abused him and the only way to stop it was to attack the man and "get locked up," according to the arraignment report.
Police said they received a 911 call from a Ledge Road home at about 4:30 a.m. on Sunday from someone who said a man had been stabbed. The witness told police she woke up when she heard screaming, then found a man on the floor.
When police arrived at the home, they found a man face-down on the floor and noticed a lot of blood. He'd been stabbed in the neck and blood and emergency medical personnel pronounced the victim dead at the scene.
State police aren't releasing his name until his family is notified.
They also noted that blood had been smeared on the living room walls.
As police were responding to the home, Alan Nadeau, 31, of Lebanon, arrived in the lobby of State Police Troop K, holding a briefcase. He had a hand on his head and told police he'd been abused as a child.
When police asked Nadeau where the knife was, he said it was in the briefcase. When police opened the briefcase, they found a knife and a laptop computer, among other things.
Nadeau told authorities he suffers from post-traumatic stress disorder and a "schizo-type disorder" and hadn't taken medication since last year, according to police.
As police interviewed Nadeau, he said he was sitting next to his father's friend and started having "flashbacks" of abuse he suffered, so he went to the basement, grabbed a "bayonet" style weapon, stabbed the victim once, ran to his room, grabbed his computer and the knife, placed them in a bag, left in his 2014 Subaru and turn himself in to police.
Nadeau has been charged with murder and is being held on $1 million bond.
State police said the incident appears to be isolated and that the public is not in danger.
