i will spend every day for the rest of my life making it up to them. reporter: ira and kelly are now living 300 miles apart in his and her prisons. so how will this saga end for them? it depends on who you ask. i don t know where this is going to go. i know i still care about her a lot. i m hoping we can get through this. the only good thing that came out of this was that we ve both come to the realization that we really love each other. reporter: and marckensy, the car salesman who played the role of a lifetime, says he s happy for the hollywood ending. the good guys won. the detectives and the prosecutor said that you re the hero in this. do you feel that? no, not at all. i felt like, you know what? that was the right thing to do. being a hero? no. they re the hero. the one out there every day. not me.
kelly finally handed over money for the hit. so how much are we talking right now? two. reporter: a $2,000 deposit. nice doing business with you. nothing until we give you the go-ahead. he said just be on stand-by. reporter: as detectives waited for ira and kelly to give the go-ahead, this melodrama took a new turn. kelly added two new targets. kelly shows up to one of the meetings and says he hasn t committed yet but he wants you to take care of two insurance investigators. reporter: kelly didn t ask for them to be killed but to be beaten up. detectives believed this new job was a way to test marckensy to see if he was the real deal. kelly asked him, are you a police officer? you re sure you re not involved with the police, right? we believe that they don t think that someone working with the police would actually have two innocent people just doing their job beat up. reporter: and they were willing to pay quickly to get it done.
but detectives fitzgerald and louzan didn t think kelly was working alone. we re thinking of another scenario. reporter: so they asked marckensy to push kelly for a meeting with her partner. and she agreed it was a good idea. i thought you said you guys talked it over, you guys been over it? yeah. we did. reporter: and then it happened. later that night, they both showed up. who was kelly s partner in kr50i78 and how far will they go to get the deed done? the money is not a problem. i m telling you right now. together they have a new job for the hitman. this is where this whole story goes a little bit hollywood. yeah, literally. when dateline continues.

like the undercover sting operation might be blown. was ira on to them? here s andrea canning with the target. the investigation had entered its third week. ira had agreed to meet marckensy, the informant, outside his medical practice. here are ira and kelly walking towards his car. the doctor comes out of his office. he s in his scrubs. he goes into the car. how s it going? how are you? all right. reporter: marckensy showed ira the photos of the insurance investigators looking like they were being roughed up. ira immediately seemed suspicious. they just happened to be standing right next to each other? yeah, so the two of them. i guess they were on break or something. he s like why are they wearing a baseball cap and a regular jacket? i said, i don t know. reporter: you re really having to think on your feet? mm-hmm. reporter: so marckensy started talking about keeping the photos. i don t want to give them to you because i don t need them for what
their mom? because i saw someone that i loved being hurt. and it was not going to come to an end. she was never going to stop. reporter: did you both imagine life without susan? of course. reporter: and what was that life without her around? peaceful. reporter: despite her fantasy of a peaceful life with susan out of the picture, ira and kelly claim they had second thoughts, but there was a problem. did you say to marckensy, we don t want to do this? yeah, i told him. reporter: and what did he say? he said there s no backing out. reporter: in an impromptu meeting where there were no police recordings, kelly claims marckensy told her a terrifying story about another client of his who wanted out. he explained to me that he has to pick up a girl and bring her to the men and they re going to be feeding her to alligators. reporter: did you take that as they could feed us to the alligators? absolutely.
