SEATTLE -- A King County sheriff's spokesman said a 68-year-old woman was jailed and released pending an investigation after an SUV plowed through a waterfront home and crashed into Lake Sammamish Friday evening.
The woman's 70-year-old partner, who was in the house, was killed; her 34-year-old daughter and 40-year-old son-in-law, who were on the deck, were critically injured.
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 was later released.
She said detectives are reconstructing what happened. 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.
"My neighbor had her grandson in her lap just moving the car, put it into gear and the car shot forward through the house and ended up in the lake about 40 feet behind there," said neighbor Kevin Connelly.
The SUV driver and her 3-year-old grandson in the car were uninjured. As of Saturday afternoon, the driver's daugther and son-in-law remained in critical condition.
A photo taken by a neighbor showed the white Jeep nose hanging over the edge of the dock, nose down into the water. According to neighbors, the Jeep was brand new and the woman may have had a problem with the gear shift.
"From what I understand from the neighbors, she was trying to operate this car and it wouldn't go into gear correctly and next thing they knew, it went right through the house," said a neighbor.
KING 5 crews were at the scene and were tweeting updates and photos on Twitter.
