An Arizona pizza slinger will spend the rest of his life behind bars for killing a coworker he thought was moving in on his crush. Tyler Ross McGuire will never walk freely again, after the 31-year-old pizza shop manager received his mandatory life sentence earlier this month for the premeditated 2023 ambush killing of perceived romantic rival Deazo Seghi. Court documents provided to Us Weekly claim Seghi, 22, worked at Rounder’s Pizza in Mesa, where McGuire was the manager. “According to witnesses, McGuire approached the vehicle and shot the victim multiple times in the chest” and neck “before running away,” according to a statement from prosecutors. “Days after his arrest, the defendant’s mother contacted police about a diary belonging to the defendant,” reads a statement from the prosecution.
