LYNNWOOD — A teenager died after falling from an overpass and hitting a semi-trailer truck early Sunday, May 12, on Interstate 5.

The 18-year-old Bothell woman, identified as Danica Plunk, fell from the Alderwood Mall overpass around 3:52 a.m., according to the Washington State Patrol. She hit a semi-trailer truck in the northbound lanes of the freeway, which caused the driver to lose control and sent the vehicle off the road and into the right shoulder, just south of Interstate 405.

Plunk was alone and struck the truck itself, not the trailer, said WSP trooper Heather Axtman.

The driver, 46 and from British Columbia, Canada was taken to Swedish Medical Center Edmonds, and a passenger was not injured.

The cause of the incident remains under investigation. Foul play is not suspected.
