A Rochester man has been arrested on suspicion of vehicular homicide in connection with the death of a Centralia High School senior in May, the Thurston County Sherriff’s Office wrote in a release Wednesday.
Donald Siegler, 25, was arrested Monday in connection with the head-on collision that led to the death of Cheyllyn Collinsworth.
Because of his own physical injury, Siegler could not be arrested until this week, the release said. He was booked into the Thurston County Jail.
Toxicology reports say Siegler was under the influence of marijuana at the time of the May 17 crash.
According to court documents, Siegler crossed the center line while traveling north on Old Highway 99 near Grand Mound, striking Collinsworth’s car. Deputies arrived to find the man sitting awake in his vehicle, and a woman who appeared to be unconscious in a second vehicle.
The female was breathing after the crash, documents say, but did not respond to deputies. One deputy observed her legs pinned in the vehicle. She was removed by medics, but died prior to being airlifted to a hospital.
Siegler did not respond to questions from deputies, according to court documents. Two witnesses indicated Siegler was pinned in his car, and said he had told them his leg hurt.
Court documents say deputies later discovered marijuana in Siegler’s car, and he admitted to smoking some marijuana “after work,” but they were unable to establish the amount of time that had elapsed.
Siegler was transported to a local hospital, where deputies obtained a warrant for a blood test.
On July 19, toxicology reports showed Siegler had 6.5 ng/mL of THC in his body, above the legal limit to drive.
