Moises Zarate Zamarripa, 37, was killed on March 18, 2014, outside a home on Oakwood Forest Drive in Antioch, Tennessee, during what police described as a robbery attempt that unfolded in seconds. Witnesses say two masked, armed men approached while Zarate and a cousin were unloading a vehicle; one attacker seized Zarate from behind and a struggle ensued while the other threatened the cousin with a gun. A neighbor heard what sounded like a backfire, saw two people flee in a light-colored compact car, and a 911 call was placed around 9:30 p.m. Zarate was alive when family reached him but died before an ambulance arrived.

Investigators traced the suspects through surveillance footage, phone and tracking data tied to a silver Hyundai, and testimony placed a small group together that evening: Quintavious Montez Patton, Donte Ricardo Swanier, Diana Reyes, and Rayvon Walker. Walker later testified that a plan to rob someone produced the confrontation; he said he grabbed Zarate, Patton fired when Zarate did not let go, and the group fled.

Rayvon Walker was arrested in late May 2014 after a juvenile court petition and arrest order; investigators indicated more arrests were expected as the case developed. If anyone knew Moises, saw activity around Oakwood Forest Drive that night, or has information about the robbery attempt, please share what is known.
