Man involved in 2020 Seattle mass shooting sentenced to 4 years in prison for amended charges

SEATTLE — The man charged in connection to a deadly 2020 mass shooting in downtown Seattle was sentenced to four years in prison Friday afternoon.

Earlier this month, on June 2, William Tolliver plead guilty to amended charges of second degree manslaughter, third-degree assault and second-degree unlawful possession of a firearm in a King County courtroom.

Tolliver was originally charged with first-degree murder, six counts of first-degree assault and unlawful possession of a firearm in connection to the January 22, 2020, shooting on Third Avenue and Pine Street.

A 50-year-old woman was killed in the shooting, and seven others were injured, including a 9-year-old boy who was walking with his family after a visit to the Pacific Science Center.

The other accused shooter involved, Marquise Tolbert, was also initially charged with murder and assault in the case, but was found not guilty last year. However, he pleaded guilty to an unlawful possession of a firearm charge.

Tolliver was released in March to electronic home monitoring at his grandmother's home while he awaited trial. Under the terms of his release, Tolliver was not allowed to have any guns or be in contact with any witnesses or co-defendants in the case. However, he was taken back into custody a couple months later after allegedly threatening someone with a gun.

Back in February, prosecutors argued strongly against electronic home detention, with one prosecutor saying in court: “Defendant’s criminal history includes prior convictions for possession of a firearm, despite being repeatedly ordered by the court not to possess a firearm, Mr. Tolliver decided to possess a firearm.”

According to court documents, Kirkland police alleged Tolliver had a gun against court orders when he threatened a man living at his grandmother’s house.
