A second person has died after an SUV drove through a waterfront home and crashed into Lake Sammamish Friday evening.
The King County Sheriff's Office said the driver's 40-year-old son-in-law, Sean Berry, died from his injuries.
The driver's 70-year-old partner also died. Her 34-year-old daughter remains hospitalized.
The driver was booked into jail early Saturday for investigation of one count vehicular homicide and two counts vehicular assault and was released pending an investigation.
Results from toxicology tests are pending.
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 not hurt.
