Nathan Collin Nate Leon was 27 when he was killed after a pizza delivery on Sunday, March 17, 2013. A resident of Commerce City, Colorado, he was working an evening shift for a Domino’s in North Denver to supplement his primary job. He was dispatched to a deserted industrial area after an order placed from a nearby payphone and never returned.

Investigators say Leon was kidnapped at the delivery location, forced into the trunk of a car, and driven about 18 miles to a field in Golden, Colorado, where he was shot multiple times and left. His car and phone were found at the scene; the motive for the attack was identified as theft of his Domino’s uniform.

Authorities identified Evan Ebel, a 28-year-old recent parolee with ties to a white supremacist prison gang, as the person responsible. Evidence recovered from Ebel’s vehicle, including a pizza box and a Domino’s shirt, linked him to Leon’s killing. Some investigators and Leon’s family have expressed concern that the murders may have been tied to a larger conspiracy involving the prison gang, and the case remains open.

Nathan Leon was a husband and the father of three young daughters; anyone with information about his killing is asked to come forward.
