It was Mrs Ganz, 25, who made the 911 call that brought the officers to their residence:
Officers Ben Cooper and Freddie Alaniz of the Joplin Police Department both fired at Ganz multiple times with their service weapons when he allegedly pointed a gun at Cooper. Ganz was shot once in the abdomen. A single live round subsequently was found in the .357-caliber revolver Ganz had in his possession, according to police.
Cooper and Alaniz were responding to a late-night 911 call from Ganz’s wife, Onya, reporting that her husband was threatening to kill himself with a gun. The confrontation with the officers took place in the back yard at the home.
