And may have helped launch it, but no one did more to further it than the father of kidnapped child Adam Walsh.

Adam’s father, John Walsh, became an advocate for victims of violent crimes and is the host of the television program America’s Most Wanted. He has also hosted The Hunt with John Walsh and In Pursuit with John Walsh.[3] Convicted serial killer Ottis Toole confessed to Adam’s murder, but was never convicted of the crime because evidence was reportedly lost and Toole later recanted his confession. Toole died in prison of liver failure on September 15, 1996.[4] No new evidence has come to light since then, and police announced in December 2008 that the Walsh case was closed and that they were satisfied that Toole was the killer.
