VIDEO: Two men were rescued from a tree in the middle of Otay River in Jamul on Monday. Cal Fire’s swift water rescue team ordinarily wouldn’t find victims stranded up a tree. But this would be no ordinary rescue. The San Diego County Sheriff’s Department said the two men started hiking from Mexico two days ago. They got as far as the middle of the Otay River behind Skydive San Diego in Jamul. Chula Vista Firefighter Willie Armas did much of the translating for the rescuers. “They were telling me they were here and trapped in that tree since this morning. They were a little bit injured," Armas said. What makes this one of the most dangerous rescues that firefighters perform is the current. It can grab a victim or a firefighter and pull them down stream. It can drag them underwater and under the debris that’s fallen because of the storm.
