On a late Saturday morning in Seattle on January 26, 2019, 51-year-old Ronnie Tyler was fatally wounded during an altercation aboard a King County Metro bus near 4th Avenue South and South Walker Street. Surveillance footage shows a dispute that began when Tyler shoved an 88-year-old passenger, Roger Mize, as Mize attempted to board. The altercation escalated when Mize drew a firearm, pistol-whipped Tyler and shot him once in the abdomen.

Both men were taken to Harborview Medical Center; Tyler died that night. The King County Medical Examiner’s Office ruled Tyler’s death a homicide. Seattle police reviewed the bus video and arrested Roger Mize, who was charged with first-degree manslaughter amid prosecutorial claims he instigated the confrontation and used excessive, reckless force.

Did anyone on that bus or nearby witness the events leading up to the confrontation?
