Direct-mail cards sent to millions of homes and a segment on CNN Headline News haven’t helped authorities find a 3-year-old Clinton boy who went missing in 1996 or the man who allegedly abducted him.

Reuben Bennett Blackwell has been missing since May 1996. He was reportedly taken by his noncustodial father, Reuben Bennett Blackwell Sr., according to police and the National Center for Missing and Exploited Children.
