KILLINGLY - A 41-year-old Maine man faces numerous weapons-related charges after shooting himself in the leg inside a Killingly residence earlier this week while demonstrating his handgun’s trigger-pull feature, state police said.

Troopers were called on Monday to Day Kimball Hospital in Putnam for a report of an individual with a through-and-through gunshot wound to his left thigh. When interviewed by police, Mountain Robicheau, of 4385 Airline Road, Wesley, Maine, said he was showing his sister the de-cocking mechanism of his Beretta 96A .40-caliber pistol when his finger slipped while he was trying to lower the weapon’s hammer.

After shooting himself inside his sister’s Robinwood Boulevard home, Robicheau said he applied a dressing to his wound, but opted not to immediately go to the hospital “since the bullet exited my leg,” according to an arrest warrant affidavit. Robicheau said the pain from the wound eventually led him to seek medical treatment.

Robicheau told police his Maine permit for the weapon had expired.

Robicheau’s sister told police she and her brother had been drinking on the day of the shooting and “did some marijuana, too.”

Police investigating the scene of the shooting found a shell casing, glass pipes typically used for smoking marijuana and a jar with appeared to be marijuana inside. Police said a search of Robicheau’s pickup truck led to the discovery of a samurai sword and three high-capacity pistol magazines each containing several .40-caliber rounds.

A gym bag was also found that police said contained what appeared to be marijuana, a .44 Magnum revolver and a 5.56mm pistol.

Robicheau was charged with three counts of carrying a pistol without a permit, illegal possession of a weapon in a vehicle, illegal discharge of a firearm, first-degree reckless endangerment and possession of more than ½-ounce of marijuana.

He was held on a $50,000 bond and given a March 3 appearance date for Danielson Superior Court.
