SCAPPOOSE, Ore. -- A driver involved in a fatal crash on Highway 30 this week was charged with manslaughter and court documents allege he was under the influence of methamphetamine, marijuana and other drugs.

An SUV driven by 39-year-old Mark Alan Thomas, of Oregon City, crossed the median and collided with a car driven by 65-year-old Wayne Harvey McCormick, of Scappoose, just after noon Wednesday, said Oregon State Police Lt. Gregg Hastings.

McCormick was pronounced dead at the scene.

Thomas was treated for minor injuries and released from a Portland hospital. He was scheduled to appear in court on June 24 at 9:30 a.m.

As first reported in the Oregonian, a probable cause affidavit alleges that Thomas drank beer, smoked marijuana and methamphetamine and took three Xanax before the crash.

He told police he was going to Astoria to check himself into rehab, the document shows.

Thomas was charged with second-degree manslaughter and driving under the influence of intoxicants.
