After 30 hours of searching for a missing 8-year old with severe autism, rescue teams turned to an unlikely source for help -- The Prince of Darkness.

Joshua Robb, an 8-year old autistic boy living in California, ran off into the San Bernadino National Forest during a lightning storm. Robb's autism made the search much more difficult. Whereas most missing people would approach the sounds of people calling their name, those with autism are more likely to have the opposite reaction.

ABC News reports that the rescue teams employed an unconventional strategy to lure the boy out of hiding -- they started using recordings of Robb's father's voice as well as music from Ozzy Osbourne. Shortly after employing the tactic, they were able to locate Joshua playing in the woods by his school nearly 30 hours after he went missing.
