William Zachary Sullivan, 29, was found in his Henderson, Kentucky, home on North Main Street with a fatal gunshot wound to the head on June 7, 2015. He was a husband, father of two young daughters, and the former owner of Bridgeview Coffee.

Investigators described a heated, day-long argument between Sullivan and his wife, Amber Sullivan, with the couple’s two children present. Authorities say the argument culminated when Amber Sullivan allegedly retrieved a handgun and shot William from the top of a stairway as he stood on the stairs below. Two 911 calls were placed—one by a child from inside the house and another by a witness outside. Amber Sullivan was arrested and charged with murder; investigators reported she gave multiple, conflicting accounts of the shooting, including that it was accidental, that she had shot at a burglar, that she didn’t know the gun was loaded, and at one point that someone else had shot him. Audio recordings of arguments from earlier that day were recovered but contained no explicit death threats.

William Sullivan is survived by his two daughters, his mother, and a brother. Does anyone have information about William, the family, or what happened that day?
