A King County Sheriff's spokesman say one man is dead and two others are seriously injured after a SUV plowed through a waterfront home and crashed into Lake Sammamish Friday evening.

Sheriff's spokesman Deputy B.J. Myers says the Jeep SUV was being driven by a 68-year-old woman. A 3-year-old boy was riding with the driver. Both were uninjured.

Myers says the dead man and the woman and man injured were inside the home when the collision happened. He says the car plowed through a room in the home, possibly the living room, and then onto the deck and dock.

TV news footage showed the Jeep SUV still partially submerged off the home's dock.

Myers says detectives are interviewing the driver.
