A Bellevue man who had accidentally been released from prison early and killed his fiance in a November 2015 car crash while under the influence was convicted of vehicular homicide and hit-and-run on Tuesday.

Robert Jackson, 39, was found to be under the influence of alcohol and marijuana on Nov. 11, 2015 when he sped down Southeast 60th Street and hit a 3,000 pound electrical box, killing mother-of-two Lindsay Hill. Jackson exited the vehicle — at one point returning to the car to grab something, according to an eyewitness — and went to Hill’s apartment before fleeing the area. Hill died at the scene from a skull fracture and lacerations to the brain.

In the hours leading up to the crash, a witness reported seeing an African-American man driving a black Lexus in Seattle repeatedly strike his passenger, a lighter skinned woman who appeared to be trying to exit the vehicle.

At one point, a coat, wallet and purse containing a Washington State driver’s license for Robert T. Jackson, credit cards issued to Lindsay Hill and a title of sale for the Lexus to a ‘Rober Jackson’ were thrown from the vehicle.

Jackson had also been charged with unlawful imprisonment based on the eyewitness statement that Hill had tried but was unable to exit the vehicle because Jackson began hitting her, but prosecutors were unable to prove it beyond a reasonable doubt as a second witness said she did not hear screaming or sounds of a struggle.

Police located Jackson the morning after the crash. Blood tests taken at 10 a.m. — more than 10 hours after the crash — showed he still had THC in his system and a blood alcohol content of 0.05. An expert calculated that his blood alcohol content would have been between 0.135 and 0.220 at the time of the crash.

In the months following the crash, it was revealed that Jackson had accidentally been released from prison early in a massive Department of Corrections error. He was one of dozens of inmates who were released early and then committed crimes during the time frame when they should have still be in prison.

Governor Jay Inslee called the situation maddening, and Department of Corrections Secretary Dan Pacholke publicly apologized to Hill’s family.

“Nothing I can say will bring back Ms. Hill. I deeply regret that this happened,” Pacholke said. “On behalf of the Department of Corrections, I apologize.”

The conviction is Jackson’s third strike, meaning he will likely be sentenced to life without the possibility of parole. He is scheduled to return to court for sentencing on August 19.
