The investigation began with a simple confession by an Arizona veteran, who claimed he and other soldiers buried Agent Orange on a United State Military base in South Korea in 1978.

Leitner has also been to the frontlines of deadly wildfires, fierce tornadoes and inside border battles with Mexican drug cartels.
