ATLANTA – “America’s Most Wanted” returns—bigger, bolder, and more determined than ever—as John and Callahan Walsh team up to track down the “worst of the worst.”

Fox News Digital spoke with the father-son duo ahead of their third season premiere on Monday, April 21. The original host, John, is back alongside his son, Callahan.

“We’re still profiling the worst of the worst bad guys, still relying on the public, but we’ve given them new ways to contact us,” Callahan said. “Back in the day, it was a phone number. Today, they can go to our social media and give us tips anonymously.”

In a new age, the Walshes have turned to “internet sleuths” to help capture fugitives. 

“It’s not about closure,” he said. “It’s about ending that chapter, knowing who hurt your beloved family member and that they’re caught. They’re going to pay for it. There’s no closure. I’ll always have that big bleeding hole in my heart for Adam, that beautiful 6-year-old boy.”

The Walshes’ story was first told in the 1983 television movie “Adam.”

“America’s Most Wanted” then premiered on FOX in 1988 and ran until 2011, when it was canceled and later picked up by the Lifetime network—though without its original host, John Walsh.  

Over the course of its run, “America’s Most Wanted” was instrumental in the capture of 1,198 fugitives.
