Shawn Conner, 54, was shot and killed late on September 30, 2021, during a violent confrontation outside a home in a residential neighborhood of Mesa, Arizona. Police were called just before midnight to the area near East Emelita Avenue and South Signal Butte Road and found Conner and 39-year-old Ivana Liversedge lying on a sidewalk with multiple gunshot wounds; both were pronounced dead at the scene.

Investigators say the encounter began as a dispute between two couples: Conner and Liversedge on one side and their neighbors, Justin Keith Peterson and his wife, on the other. Tension reportedly stemmed from a recent end to a relationship between Peterson and Liversedge. The argument escalated outside the residence, both sides produced firearms, and Peterson was said to have fired nearly three dozen shots at Conner and Liversedge. Mesa police identified Peterson as the primary suspect and announced his arrest on suspicion of second-degree murder and reckless discharge of a firearm in connection with Liversedge’s death; detectives were still reviewing possible charges related to Conner’s killing.

Are there witnesses or neighbors who saw the confrontation or the moments leading up to it who can share what they remember?
