David Mauricio Macias Hernandez was last seen in Arizona on February 28, 2008, at age 29. He is Hispanic, with black hair and brown eyes, and estimated height between 5 feet 6 inches and 5 feet 8 inches; pants size 36 and shoe size 9.5. His body bears several distinctive tattoos: Eva on his ankle; an eagle with Colima on his chest; junior on one shoulder and Elizabeth on the other; and hands holding a rosary with the name angela on his back.

His last known location in Arizona is not specified, and family members have wondered whether he crossed into Sonora, Mexico, or disappeared within the state. The case is listed with the Pima County Office of the Medical Examiner under FSC MPR 971. The disappearance was reported on July 10, 2009, and an official record was created on July 30, 2012. Few leads have emerged and the case remains open.

If anyone saw David around late February 2008 or has information about his possible movements across the Arizona–Sonora border, please come forward.
