Derek Blaylock was biking home from the bus stop on his way back from work when Kevin Brewer, 51, allegedly struck him with his pick-up truck and drove away from the scene. Blaylock died within an hour. He was 50 years old with a wife and two young children.

Our deepest condolences to his family and all his friends.

“On Tuesday morning, September 21, 2016, [50-year-old] Derek Blaylock dropped his son off at elementary school, parked his car, and rode his bicycle to the bus. He would never see his son again,” the King County Prosecutor wrote in the charging documents. He would be killed while biking on his way back that afternoon.

Blaylock would be the second person Brewer has allegedly killed while driving. He killed Nicole Cheek, a 58-year-old grandmother who was walking in Marysville in 2008, the Herald reported at the time. Brewer also left the scene in 2008, leaving Cheek for dead. Her body was not discovered for more than an hour. Brewer eventually came forward and pleaded guilty to felony hit and run. He said he fell asleep while driving and thought he had hit a mailbox. He was sentenced to three and a half years in prison and was released in December 2011, the Seattle Times reports.

Despite his time in prison, investigators found that “[b]etween 2007 and 2016, Brewer was responsible for at least 10 collisions in which the driving behavior was consistent with that of a driver impaired by alcohol or drugs, or by a fatigued/drowsy driver.” Brewer has sleep apnea, and friends told investigators that “he appears to doze off periodically,” according to the charging documents.

“He is well aware that he is at grave risk for falling asleep while driving,” the Prosecutor noted.

He is not yet in custody, and a warrant has been issued, the Seattle Times reports. His attorney told prosecutors Brewer would be in court for arraignment next week. Prosecutors have requested $100,000 bail with the additional order not to drive.

“This is the second person killed by the defendant while driving,” the Prosecutor wrote in the charging document. “He is a danger to the community.”

Blaylock was biking southbound on 1st Ave NE near NE 95th Street around 4:20 p.m. September 21, 2016, when Brewer struck him.

Due to Northgate Station construction, there was a Jersey barrier along the side of the street at the time. Brewer drove his pickup so far off the road that his truck went up the barrier before coming back down onto the roadway. That’s when he ran over Blaylock.

Brewer initially left the scene, then made a hasty left turn into a driveway before getting out of his truck. A witness followed him and confronted him, told him what he did and walked him back to the scene. He told witnesses that he did not realize he hit anyone or anything despite his truck running up the barrier and slamming back onto the road.
