the one responsible for this. >> kranke grilled him for hours. but janos was insistent he had nothing to do with archie mcfarland's murder. they didn't find a speck of blood on his clothes or any scratches on him of any kind. with no history of committing any kind of crime, was it possible janos wasn't the killer? the detective had an idea. mary ann wanted to see her former lover in jail. what if they taped the conversation? so the two met for the first time since archie's murder as the tape rolled. >> how could you do such a horrible thing and think you are a man? if you get out of here alive, i'll kill you. do you know what you've done? you've destroyed me. >> i didn't do what you accuse me. i did not do it. >> if i had a gun, i would blow your damn brains out right now. >> at one point mary ann became so enraged, she even spat on him.
