Man accused of ‘lying in wait’ before running over, killing a woman outside the Bellevue YMCA

Bellevue deadly crash

BELLEVUE, Wash. — A Bellevue man is accused of running over 88-year-old Shinko Oshimo in the Bellevue YMCA parking lot and killing her, then driving to Tacoma to hit two other pedestrians.

Mark Alexander Adams has been charged with first-degree murder and felony hit and run.

According to court documents, Adams allegedly was ‘lying in wait for a pedestrian victim’ outside of the gym on February 28.

Documents claim he drove directly towards her, hitting her hard enough that she came up onto the hood of his car before running her over.

Police say they were able to get Adams’ license plate number off the YMCA’s cameras.

“This is incredibly difficult for the victim’s family,” Casey McNerthney, spokesperson for the King County Prosecuting Attorney’s Office, said. “To have to go through this just sounds awful.”

Documents state that after Adams left Bellevue, he headed for Tacoma, where he allegedly hit other people with his car that same day.

Tacoma incidents

In the first incident, according to the documents he followed someone on a skateboard, trying to match his pace.

“One of the victims suffered severe injury from the impact yet managed to roll out of the way of the Defendant as he reversed his car backwards to hit that victim again,” the documents state.

In the second incident, documents said he drove into a gas station parking lot, toward a truck driver who was heading back to his vehicle, then drove around a building and hit a different person from behind.

“The victim flew over the hood and windshield,” the documents state. Police say the person wound up with a spinal fracture.

Court documents say Adams was found the next day in Port Townsend, where his phone location pinged. Court docs also say his phone data reportedly placed him at all three hit and runs.

Protection order

According to the court documents, Adams has an active protection order against him out of King County, filed by his family.

He’s accused of stalking his elderly mother and her husband and using a knife to hold the couple up.

Escape from Western State Hospital

A decade ago, Adams and another individual escaped from Western State, a psychiatric hospital in Lakewood.

Adams was arrested a day after the escape in Des Moines. Witnesses say he took a bus from the Lakewood Transit Center to Federal Way and asked how to get to the airport.

His co-escapee, Anthony Garver, was arrested in Spokane two days after the escape. Garver was accused of murder but was found not competent to stand trial.

Prosecutors call Adams a ‘danger to the community’ and set his bail at $5 million.

“Prosecutors asked for him to be held on $5 million bail,” McNerthney said. “That’s both for the current allegations and the seriousness of that, but also history that we wanted to bring up before the court.”
