An American gun collector who introduced several weapons into sexual play with two other men contended the weapons were intended to fulfill a sexual fantasy.
Instead, a lethal combination of drugs, extreme sex and Russian roulette put him on trial for manslaughter.
Both the defence and prosecutors said there was no intention to kill. But prosecutors said defendant Bruce Lavallee-Davidson was responsible for ensuring his gun wasn't loaded when it was being handled. He was convicted Wednesday and faces at least four years in prison.
The trial shed light on a dungeon in a South Portland home that was filled with sexual toys that three men used as a drug-fuelled escape from reality.
Assistant Attorney General Lisa Marchese said the focus should be on the handling of the gun - not the sexual acts that were going on in the victim's basement. The victim, Fred Wilson, 50, died of a single gunshot wound to the head on April 18, 2009.
"You just don't hold a gun to someone's head and pull the trigger without making sure it's not loaded. And at the moment he pulled the trigger, he didn't know," she said.
Defence lawyer Tom Hallett told jurors the men had been using guns as part of their sexual play and that the victim was a thrill seeker who may have slipped a bullet into the .44-caliber Rossi revolver unbeknownst to Lavallee-Davidson, who'd previously checked to make sure the gun was unloaded.
Manslaughter carries a maximum sentence of 30 years in state prison in Maine. Because a gun was involved, the minimum sentence is four years, Marchese said.
The bespectacled Lavallee-Davidson, a farmer with short gray hair and a goatee and dressed in a sport coat, gave the appearance of a college professor in the courtroom. He showed no visible reaction to the verdict, and left without speaking to reporters. Hallett said the outcome was "devastating" for him.
The fatal shooting happened after Wilson, Lavallee-Davidson and a third man had been smoking pot, consuming the party drug GBL, huffing aerosol inhalants and having sex over a 12-hour period in the basement of Wilson's Colonial home in a middle-class neighbourhood two blocks from the ocean.
The third participant, James Pombriant, 65, testified he first thought the others were playing a sick joke on him when he saw the flash of a handgun after hours of partying.
Pombriant, who was engaged in a sex act with the victim when the shot rang out, says there was a moment of silence before Lavallee-Davidson said, "I think I killed him."
Lavallee-Davidson, 50, contended the killing was a tragic accident.
His lawyers said their client checked not just once - but three times - over the course of the night to make sure the revolver wasn't loaded. They contend the victim loaded a bullet into the revolver's chamber while Lavallee-Davidson slipped out of the room to use the bathroom.
When Lavallee-Davidson returned, Wilson asked him to put the gun to his head and pull the trigger to intensify his pleasure, the defence contended. On the first try, there was a click when Lavallee-Davidson pulled the trigger. Wilson asked him to do it again, and there was a flash, the defence said.
After the shooting, Pombriant and Lavallee-Davidson left Wilson's body behind for hours before Pombriant called police. Police recovered the handgun used in the killing and a .12-gauge Mossberg shotgun that Lavallee-Davidson had taken to Wilson's home for the sex games.
