How Ronald Cyr’s Booby Trap Killed Him Instead of an Intruder

On Thanksgiving night in 2019, Ronald Cyr, a 65-year-old man from Van Buren, Maine, called 911 to report that he had been shot. When emergency responders arrived, they discovered that the fatal gunshot had come from a homemade booby trap that Cyr had installed inside his own home.

Ronald Cyr’s Homemade Trap

Investigators found that Cyr had rigged his front door with a handgun attached to a homemade firing mechanism. The device was designed to discharge if someone opened the door, potentially shooting anyone who entered the house.

Authorities believe Cyr accidentally activated the trap himself, causing the handgun to fire and fatally wound him. He was taken to a nearby hospital, where he was later pronounced dead.

Police Found More Dangerous Devices

The discovery of the trap prompted a large emergency response. Officers found several other suspicious homemade devices throughout the property and called in the Maine State Police Bomb Squad to secure the home safely.

Investigators spent hours searching the residence to ensure no additional traps posed a danger to first responders or anyone else entering the property. Officials later confirmed that Cyr died from the accidental discharge of one of his own devices.

Why Booby Traps Are Illegal

Law enforcement agencies warn that homemade booby traps are extremely dangerous because they cannot distinguish between an intruder and an innocent person. Family members, emergency responders, delivery workers, or even the homeowner can become victims.

In the United States, setting deadly booby traps to protect property is illegal in every state. Courts have consistently ruled that people cannot use lethal force through automated devices against someone entering a property.

A Tragic Lesson

Ronald Cyr’s case became a stark reminder that homemade weapons and booby traps often create greater danger for the person who installs them than for anyone else. Instead of protecting his home, the device he built ultimately claimed his own life.
