A King County sheriff's spokesman says a 68-year-old woman is in jail after an SUV plowed through a waterfront home and crashed into Lake Sammamish Friday evening.

Sgt. DB Gates says the woman was booked into jail early Saturday for investigation of one count vehicular homicide and two counts vehicular assault.

She said detectives are reconstructing what happened. Results from toxicology tests are pending.

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

The SUV driver and a 3-year-old boy in the car were uninjured.

Gates says the man who was killed was either the female driver's husband or partner.
