Three people are dead after a small plane crashed in Chilliwack, B.C., according to RCMP in the city about 100 kilometers east of Vancouver. The plane crashed behind a motel near the airport, killing the pilot and everyone on board, Sgt. Pete Healey said. The RCMP are notifying the victims' next of kin, Healey said. It's still unknown what caused the Piper PA-34 Seneca, a twin-engined light aircraft, to crash. The Transportation Safety Board of Canada said it's sending investigators. "The scene is contained and there were no other reported injuries or risks to the public in the area," RCMP said in a news release. B.C. Emergency Health Services said five ambulances and a paramedic supervisor responded to the crash. Two air ambulance helicopters were en route but canceled before reaching the area.
