Former Seattle Seahawks player Derrick Coleman has been charged with vehicular assault and felony hit-and-run for his role in an October crash in Bellevue that seriously injured the victim, according to the King County Prosecutor’s Office.

Coleman — who is now a free agent — was allegedly driving his 2015 green Dodge Ram pickup truck at a high speed on Southeast 36th Street when he hit a car driven by a 57-year-old Bellevue man, flipping it over and pushing it up onto a retention wall. The football player then reportedly fled the scene and was located by Bellevue Police a few blocks away.

He told police he had smoked a synthetic “designer drug” called “spice” prior to driving that night, according to the police report. Investigators also found a glass pipe with a tar-like residue, multiple packets of synthetic cannabinoids named “f’d up” and “mad pitbulls,” packages of “edibles” (items containing THC, the chemical responsible for marijuana’s psychological effects), mouthwash and redness-relieving eye drops.

While police noted that he exhibited signs consistent with being impaired and was unstead on his feet, Coleman passed a field sobriety test and a blood test conducted several hours after the crash did not find any drugs in his system.

“I think that experts will tell you the substance that’s the biggest challenge to detect is “spice,” but I’m not an expert in the area,” Bellevue Police Chief Steve Mylett told reporters during a January press conference, adding that the time that elapsed between the crash and the blood test could have allowed the drug to leave his system.

Coleman’s lawyer, Stephen Hayne, told the Reporter that the police department was just trying to make the football player look bad.

The Seattle Seahawks initially suspended Coleman following the collision, but reinstated his days later. Head coach Pete Carroll said that he had received an explanation for the car crash that he found sufficient.

If convicted of both charges, Coleman could face a sentence of 12 to 14 months in jail. He is scheduled for arraignment on June 16.
