On November 29, 2016, 27-year-old Ahmed Sheikah was shot multiple times while riding a King County Metro Route 169 bus in Renton, Washington. Witnesses say a fellow passenger, 21-year-old Faisal Guled Adan, stood up after a brief exchange in a foreign language, fired at close range, then moved to the front of the bus, brandished a revolver at the driver and demanded to be let off. Passengers fled in panic. Two nearby residents saw a man come out from behind a vehicle with his hands raised, say he admitted he was the person police sought, and held him until officers arrived.

Sheikah was taken to Harborview Medical Center with gunshot wounds to the head, shoulder and hand and died two days later. Investigators found the two men barely knew each other; Adan later said he’d believed Sheikah planned to harm him after overhearing a phone call, but admitted he had not seen a weapon and had used drugs and alcohol before boarding. Adan was charged in the killing and later pleaded guilty. The court sentenced him to 353 months in prison.

Did anyone on that bus or in Renton at the time notice anything about the interaction between the men before the shooting?
