Tigard man convicted in fatal car crash

Hit-and-run case leads to six years in prison, lifetime driving ban

OnderdonkA Tigard man will spend more than six years in prison after he fatally struck and killed a man in a car crash in March.

On Friday, a Washington County jury convicted Bryan Onderdonk, 29, of second-degree manslaughter, felony hit and run, second-degree burglary, intoxicated driving, second-degree criminal mischief and third-degree theft.

Jurors deliberated for about an hour and a half on Friday evening before reaching their decision.

Onderdonk was driving on Oregon 219 near Farmington Road at about 9 a.m. on March 24, when he T-boned a car turning onto the highway.

Onderdonk had methamphetamine in his system and was speeding when he struck the car, which killed Marcus Castillo, 50, of Vancouver, Wash.

Castillo worked in landscaping and was headed to a job at the time of the crash. He died at the scene.

Onderdonk fled through a wooded area and through three properties on Bald Peak Road before he was eventually arrested four hours later.

He was spotted in a man’s shed barefoot and wearing only shorts. He asked to use the man’s telephone, then fled to another house, where he reportedly stole a 92-year-old man’s coveralls.

Onderdonk was arrested after he broke into a woman’s home and laid on her bed while she hid in a closet.

The woman fled out a bedroom window after he began using the woman’s shower. She found Washington County deputies and Hillsboro police officers searching the area for him.

Onderdonk’s lawyer, Michael Sahagain, said that although he had methamphetamine in his system, Onderdonk was actually exhibiting the signs of Post-Traumatic Stress Disorder and was not under the influence of the drug when he crashed the car.

Onderdonk served in the U.S. Air Force in Iraq for seven years.

Sahagain said Onderdonk was experiencing a war flashback and had instinctively fled the scene. Onderdonk admitted to taking meth, but said it was a day earlier. He claimed he was no longer under the influence of the drug, but it was still in his system.

But prosecutors said the meth use was the direct cause of the crash. Onderdonk had been acting erratically before the crash, prosecutors said. He knocked on a stranger’s door in Beaverton and asked to trade cars about a half-hour before the crash.

Second-degree manslaughter is a Measure 11 charge carrying a mandatory minimum sentence of six years, three months in prison.

Washington County Circuit Judge Charles Bailey sentenced Onderdonk to the mandatory minimum sentence on Tuesday morning. Deputy District Attorney Jason Weiner asked for a harsher sentence than the minimum, asking the judge to add time for the hit-and-run conviction.

“I believe there’s a difference between killing someone in a manslaughter and staying on the scene versus killing someone in a manslaughter and fleeing the scene in attempt to evade response,” Weiner told The Times on Tuesday.

The judge declined to add additional time to the mandatory minimum sentence. In addition to his prison sentence, Onderdonk’s driver’s license was suspended for life. He will undergo mental health and drug treatment in prison.
