Benjamin McIvor, 44, died after a physical altercation in Phoenix in the summer of 2017. The confrontation began as a dispute late on a Saturday night in July and escalated in the parking lot of a local sports bar, where McIvor suffered a head injury after being struck and falling to the ground.

McIvor was a football coach at Mesa Community College, remembered by colleagues and players as a mentor and positive influence. He was also a husband and father; his death left his family and the local sports community in mourning. Phoenix police identified a suspect, Robert J. Malcomson, after witnesses provided accounts of the incident, and Malcomson was arrested and charged in connection with the death.
