and the stuff that we saw, it floored me. >> we got do a box where it says that alex hernandez was aan affidavit. i heard there were no other suspects in this case. well, if he's not a suspect, how is there an affidavit stating he's a suspect. seth and i sat back and said well, what else is it that we don't have? >> as seth's third trial loomed, his team caught a break. seth's former co-defendant, pablo aybar had gained access to files police deemed irrelevant to the case. and thus, never disclosed. >> he gets 50,000 pages of public records, everything we've gotten and a lot that we haven't, that made all the difference in the case, i think. >> seth and i, at this point, start going through the documents, and i just found things that had never been disclosed. there are so many leads that have gone unanswered. >> some of those leads concerned the man at the center of the murders, butch casey. butch's reputation of being a playboy also included reputed ties to the mob. >> you have confidential informants saying, hey, man, this guy just got beat up by the mafia. they put him in the back
