Rescue crewsd are searching for a San Diego man who went missing on Sunday while exploring the caves at Anza-Borrego Desert State Park in southern California. Guillermo Piño, 26, was camping with his family near the Arroyo Tapiado mud caves when he set off barefoot to explore one of the hundreds of caves in the park. Authorities say Piño is an experienced hiker, but he was not carrying water, food, a flashlight, or a cell phone at the time of his disappearance. "We don't know if he fell into an open part of a cave and is trapped underground or somehow wandered off or if he fell or started exploring a cave and became disoriented," said Jan Caldwell, a San Diego County Sheriff's Department spokesperson. There is a network of more than 22 caves at Anza-Borrego State Park, some up to 1,000 feet in length.
