The Bellingham Herald reports that North Whatcom Fire and Rescue Chief Ron Anderson says a father and two boys were on the dock Sunday evening when a vehicle broke through a gate.
Blaine police spokeswoman Lisa Moeller says a 7-year-old boy was hospitalized with serious injuries to both his legs.
Moeller says divers found the truck Monday morning, about 100 feet from the end of the pier.
Royal Canadian Mounted Police notified Blaine authorities that a man's body had been found on the beach at Peace Arch Provincial Park. Identification on the body matched that of the truck owner. The man's name was not immediately released.
