Humberto Martinez Ruvalcaba, age 26, was last seen on January 26, 2011, in Santa Paula, California. On the day of his disappearance, Ruvalcaba left his residence and has not been heard from since. His family has had no contact with him since that day, raising significant concern about his whereabouts. At the time of his disappearance, he was wearing a long-sleeved shirt and shorts. Ruvalcaba is described as a Hispanic male with brown hair and brown eyes, standing 5'5" and weighing about 130 pounds. He also has several tattoos, including the name "Juana" on the left side of his chest and additional tattoos on his back and forearm.
