In his free time Walton is a vigilante who hunts con artists. The first con artist Walton put in jail was Marianne Smyth aka Mair Smyth aka Marianne Clark, who scammed hundreds of thousands of dollars from 43 victims, including Walton himself, in the United States and Europe, using an elaborate series of confidence tricks. She was convicted of stealing money from him and spent about two years in jail. After Smyth's Los Angeles conviction in 2019, Walton worked with authorities in the UK to get Smyth extradited and convicted in Northern Ireland in Sept 2025.
Walton also works as a television producer on reality television shows like American Ninja Warrior for NBC, Shark Tank for ABC and Savage Builds for the Discovery Channel. His career in unscripted television was preceded by a 10-year stint as an Emmy Award-winning TV news reporter and producer at local stations KHOU-TV in Houston, Texas, KABB-TV in San Antonio, Texas and WSVN-TV in Miami, Florida.
