A woman died in a collision Monday morning on I-405 in Bellevue after her car stalled in the middle lane because she had hit a deer.
The 24-year-old woman called 911 around 4:30 a.m. to report she had struck the deer and she believed her car was disabled on southbound I-405 just north of I-90.
Washington State Patrol Trooper Chris Webb says the woman called 911 several times, and apparently her boyfriend.
Another trooper and the woman's boyfriend were on their way to assist the woman when 911 received a second call that a semi truck had hit a vehicle in the same area.
The truck hit the woman's car and the impact was so severe, it crumpled the entire rear portion of the car and then pushed it several hundred feet.
The victim was alive when paramedics arrived at the scene, but she could not be saved. Troopers say she was wearing a seat belt.
Webb says the semi truck driver is cooperating with the investigation.
The woman reported to dispatchers that she believed her car, a 2006 Toyota Scion, was disabled after striking the deer, Webb says. There was some front-end damage, but investigators weren't sure that was the case.
Troopers don't believe drugs or alcohol factored in the crash.
The state Transportation Department says the crash caused about a 2-mile backup. All lanes of traffic reopened on I-405 around 8 a.m.
