Matthew Clark Restelli, 42, was shot to death on July 12, 2024, in American Fork, Utah, after traveling from his California home to meet his estranged wife, Kathryn Restelli, with the expectation of reconciliation. Investigators say Matthew was lured to Kathryn’s mother Tracy Grist’s home; authorities describe the killing as part of a premeditated plot involving Kathryn, Grist, and Kathryn’s brother Kevin Ellis.

Police allege the trio tracked Matthew’s truck from California using an AirTag. Responding officers reported the knife was found in Matthew’s right hand though he was left-handed, and that the knife’s position appeared unnatural; an autopsy showed a gunshot wound to the same wrist that held the knife. Text messages among Kathryn and family members and a two-minute gap between the shooting and the 911 call were cited as evidence of a conspiracy.

Kevin Ellis was arrested and charged with murder and other offenses. Kathryn Restelli and Tracy Grist were charged with conspiracy to commit murder, obstruction of justice, and domestic violence in the presence of a child; Kathryn later pleaded guilty to murder and conspiracy as part of a plea agreement. Did anyone in American Fork or California see Matthew en route or have information about communications with him before July 12?
