Man dies after crashing down 150 foot embankment in Kittitas Co.

Fatal Crash Cle Elum


At the request of the decedent’s family, KAPP-KVEW Local News reached out to the Washington State Patrol to review any factual errors and provide additional context related to this crash.

Trooper John Bryant told KAPP-KVEW on Wednesday that Mr. Kossow’s vehicle went approximately 150 feet off the roadway and down an embankment; the vehicle was located 150 feet from Interstate 90 after it left the roadway and traveled down the embankment.

Per WSP policy, all deadly crashes are reviewed by the county coroner, who is tasked with determining the cause of death.

“No cause of death is really official until a competent medical person says so, like the coroner,” said Trooper Bryant. “It’s ‘unknown’ on any fatality until the coroner says, ‘here’s why he died,’ ‘here’s why she died,’ ‘blood says this,’ ‘toxicology says this.'”

Toxicology results are expected in approximately two weeks.
