Yates committed his first murders in 1975, when he shot and killed two college students who were picnicking Many of his subsequent victims were sex workers working along East Sprague Avenue who had substance abuse issues, and Yates would often do drugs with them and other sex workers.

All of his victims died of gunshot wounds to the head or heart.

Eight of the murders were committed with a Raven .25-caliber handgun, and one attempted murder was linked to the same model of handgun.
