A Maine man who rigged his house with traps to protect residence was killed after he set off one of his own machines.
Van Buren police said they were summoned to Ronald Cyr's home on Thanksgiving Day in the early evening after calling 911 to report he had been shot.
Police said the police on the scene then discovered that the front door had been trapped with a device designed to fire a handgun if someone tried to enter through the door.
Other unknown devices were also discovered, prompting alarmed investigators to contact the police's bomb squad in Maine, the police said.
After a thorough investigation, it was determined that Cyr had been shot dead following the unintentional rejection of one of his homemade appliances, they said.
