I cannot believe you produced the whole Dateline on Nicholas Rossi and never once mentioned DNA. So, we as the audience had to sit through several segments where it was NEVER once mentioned. In the beginning there was mention of the rape DNA. So, how easy it would have been to take his (Arthur's) DNA and see if it matched. Instead I guess you chose to TRY and make a whole show out of the mystery of it all. Seems a little beneath of you.
