>> the fbi, the local police, and the u.s. attorney's office simply want this case to be closed. but is it? tonight you decide. did the fbi catch all the suspects? did the fbi let one of them walk? and did the fbi make a mistake putting blame on a pizza delivery man whose secrets blew up in a parking lot? it was a hot thursday afternoon. jean heid was expecting to see her brother at a party that night, but she had one errand to run. a quick shopping trip on erie's peach street. but there was trouble. police had blocked the road. cops and cars everywhere. she turned around and went home. >> i come home, and i tell my husband something happened up there. i said we don't know what happened.
