The National Emergency Number Association announced that John Walsh, host of the popular “America’s Most Wanted,” which appears on the Fox television network, to keynote its annual conference June 13-17 in Tampa, Fla. Walsh is scheduled to speak on June 14.

Walsh became an advocate for victim’s rights and missing children after his son Adam was abducted and murdered in 1981, a highly publicized case that was dramatized in two television movies. No one was ever convicted in the case. Walsh’s subsequent advocacy work led to passage of the Missing Children Act of 1982 and the Missing Children’s Assistance Act of 1984, which led to the founding of the National Center for Missing and Exploited Children.
