Two boys strangled by escaped snake in Canada

Two young boys have been killed by a python which escaped from its enclosure in a pet shop in Canada and slithered through a ventilation system into the apartment upstairs, police said today.
The boys, aged five and seven, were visiting the apartment of a friend above Reptile Ocean, an exotic pet shop in Campbellton, New Brunswick, said Royal Canadian Mounted Police Constable Julie Rogers-Marsh.
