David Cummings was a certified search and rescue technician for the past 20 years, rescuing hikers and finding remains in California. He thought he left that life behind when he moved to Las Vegas. But then hiker Ron Kirk went missing in Red Rock, and suddenly David found himself in charge of hundreds of volunteers. Ron's body was eventually found, and now David is starting Red Rock Search and Rescue.
The independent group aims to help families continue to search for loved ones. David Cummings talks about the new search team, and shares harrowing stories of his own search-and-rescue days, and what to do when people disappear into thin air.
