Police in Canada said that four young people have died after a small plane crashed in southwest Ontario, AP reported. Police said Saturday that a single-engine Cessna crashed Friday night in a cornfield near Moorefield, Ontario. Const. Keith Robb says all four occupants, three men and one woman, were pronounced dead at the scene. Robb says the victims are believed to be young adults in their late teens and 20s. Police say it\'s unclear how long the plane had been in flight before it crashed. Officials say they don\'t believe weather was a factor since it was a clear night. Bob Connors, the general manager of the Waterloo-Wellington Flight Centre, says the plane was a rental. Connors would not comment on the experience of the pilot.
