A late Saturday morning argument in Mesa, Arizona, ended in a fatal shooting that killed 57-year-old William Henry Harrison on April 11, 2015. Deputies responded about 11:30 a.m. near 113th Way and Meridian Road and found Harrison with a gunshot wound; CPR was performed but he was pronounced dead at the scene.

Investigators identified 39-year-old Scott Stradling as the person who had been involved in the argument with Harrison and believe Stradling fired the shot that killed him. Stradling was arrested; although there were initial claims of self-defense, authorities moved forward with a murder charge.
