The horrifying ordeal took place after the 115-pound, 15-foot-long snake got free from its cage at a pet store, made its way into the building's ventilation system and into the home above the store where the five and seven-year-olds - reportedly brothers - were sleeping during a sleep-over.

A criminal investigation is under way into the deaths of two boys who were killed by a python that escaped its enclosure at a pet store in Canada, police said Monday.

Police arrived at the apartment in Campbellton, New Brunswick, at 6:30 a.m. and found the two boys, ages 7 and 5, dead. A friend of the brothers was sleeping in another room and was unharmed, according to Police Constable Julie Rogers-Marsh.

Royal Canadian Mounted Police (RCMP) officials told the Canadian Broadcasting Corp. that the owner of the pet store, Jean-Claude Savoie, was hosting the two boys for a sleepover with his own son. Savoie reportedly discovered the bodies of the two boys and called the police. 

Rogers-Marsh said the snake, described as an African rock python, was believed to have made its way into the apartment through the ventilation system overnight. 

The snake was captured and is in the possession of police. Calls to the pet store were not returned Monday. In New Brunswick, pet stores are allowed to sell non-venomous snakes of up to 3 meters, or just under 10 feet, in length. 

"It's very, very unusual and very tragic and difficult for everyone involved," Rogers-Marsh said.
