On the night of September 30, 2021, a neighborhood dispute in Mesa, Arizona, ended with two people shot and killed on a sidewalk in the 700 block of South Del Rancho. Ivana Liversedge, 39, and her companion, 54-year-old Shawn M. Conner, were found with gunshot wounds and pronounced dead at the scene shortly before midnight.

According to police reports, the confrontation began as an argument between two couples. Liversedge and Conner became involved in a dispute with Justin Peterson, 41, and his wife after a recently developed then soured romantic relationship between Liversedge and the Petersons. The argument reportedly became physical when Peterson’s wife and Liversedge fought, and investigators say Justin Peterson produced a firearm and shot both victims.

Mesa police arrested Justin Peterson on suspicion of second-degree murder and reckless discharge of a firearm. Does anyone in the area remember seeing activity on Del Rancho that night or have information about the parties involved?
