A couple in their 20s is facing domestic violence charges, state police say, after they allegedly assaulted the woman’s mother in her car during a dispute in Bellevue around midnight Friday.

Washington State Patrol Trooper Chris Webb said a woman was driving her daughter, 20, and the daughter’s boyfriend, 22, southbound on Interstate 405 when an argument ensued.

The driver exited the interstate and stopped at the Newport Hills Park and Ride on the 5000 block of 113th Place Southeast, where she demanded the couple get out of her car, Webb said. The couple then allegedly assaulted the driver and then fled.

Bellevue Police set up a staging area for WSP at and park and ride and Kirkland provided a K-9 unit, said Bellevue detective Amanda Jensen. The King County Sheriff’s Office provided air support, and the two suspects were found hiding nearby using a thermal imaging camera.

The driver was taken to Overlake Medical Center to be treated for her injuries and then released, Webb said.

“It’s going to be misdemeanor (domestic violence) assault,” the trooper said, adding reports of the suspects having a knife or machete were unfounded. “It was just somehow they assaulted the driver.”
