Hollywood. The money theyre spending, thats very real. But first the nightline 5. Number one in just 60 seconds. Good even. Im byron pitts. Hiring a hit man to make someone disappear. More than just a hollywood plot line. Its a crime thats more common than you might imagine. The people youre about to meet thought murder might be the best way out of their relationship problems. Or at the very least an easy payday. One wouldbe killer allegedly wanted his own mother dead. Heres abcs john donvan. Started as a joke. And it got out of hand. And its cost him everything. Reporter big sky country. Land of open plains. But closed up inside this house, a family with a dark story. Everything changed in a matter of a few hours. Reporter it begins on the outskirts of billings four years ago at this used car lot when an fbi agent stops by to deliver to owner Dana Campbell an unthinkable message. He asked to speak to me in private. He said, i hate to be the one to inform you of this but weve been notified that there has been a contract put out on your life. A contract out for your life . It just sounds it sounds insane. Reporter not as insane as what comes next. The fbi agent says he has a pretty good idea of who took out the hit. It was her own son matthew. They have enough evidence that they are safe in saying that it was my brother who had done that. He had contacted an undercover fbi agent and was making plans to have him kill my mom. Reporter the big question, why . Nicky says she thought their family had an unbreakable bond. They enjoyed family trips together and only bickered the way normal brothers and sisters do. We picked on each other and my little sister a lot. But end of the day we knew we had each other. Reporter Matthews Family thinks he wanted something more. His mothers money. My two girls think now, maybe, if my estate had been divided into thirds after i passed away, maybe he might have even considered, you know, killing them so he could have 100 of it all. Made me question everything that i ever knew about him. You know. Was i next . Was my sister next . Reporter well get back to that in a minute. Turns out trying to hire someone to make a loved one disappear may be more common than you think. Meet julia marfeld who after pleasantries gets right down to it. In one of the most staggering conversations you may ever happen to overhear, shes planning her husbands murder. You said something about a gunshot, is that how you want me to do it, shoot him . Unless you can do it painlessly, i would i would prefer to use either a knife or a gun. Quick and easy. Less painful. Where do you want me to shoot him . Do you want an open casket, closed casket, what do you want . I want an open casket. Reporter the stuff shes worried about, like the mess it might make in the house . It would be messy. Reporter she didnt need to worry about because her husband is still alive. The guy shes talking to on the right hand, he is an Undercover Police officer. So why not just divorce her husband . Well, there was the insurance money to be had if they were dead. And then there were his feelings to consider. Divorcing him, i didnt want to worry about the judgment of my family, i didnt have to worry about breaking his heart, stuff like this, if i got a clean getaway. Reporter not so clean after all. She is now serving a sentence, at least five years and eight months. Hiring the wrong guy turns out to be a costly but not uncommon mistake. What they do is they step to a friend or associate or someone that they knew in their past. And what happens in the vast majority of the time, the person they step to goes to law enforcement. Really . They get ratted out . Im 5,000 sure. Reporter thats what happened to delia dippolito in 2009 allegedly negotiating terps for her husbands murder. Tours out the supposed killer for hire in the drivers seat was also an undercover top. Dippolito was called home by police and given the false news that inside her husband lay dead. Murdered. Okay, im sorry to tell you, maam, hes been killed. Oh, oh hes been killed, man. No, no reporter then they got her into an interrogation room. I just want to see my husband. She continues to speak as a shocked widow. As far as she knows her husband is dead. Then they tell her the killer is one of their own men. Thats an Undercover Police officer. We filmed everything that you did. Recorded everything that you did. I didnt do anything. Listen to me. I didnt do anything. Youre going to jail. I didnt do anything, please, i didnt do anything. Reporter finally they tell her that her husband is still alive. Your husband is well and alive. Thank god. Oh, yes. Can i see him . He doesnt want to see you. Reporter delias husband didnt believe her when she got him on the phone from jail. You know more than anybody its not true. You sent me down to have me killed, i heard that. That is not true. How is that not true . How could you believe that . I heard your voice. Like i didnt do anything. It doesnt matter, you can hire 5,000 lawyers, theyre charging your ass. They have your voice, your face, everything, on tape. Reporter dippolito was sentenced to 20 years. Just last week, an Appeals Court reversed that conviction because the jury was never asked how much they knew about her case. I didnt do anything and reporter dippolito was granted a new trial. Through his lawyer Mike Dippolito says hes disappointed. People believe in their naive state that they can step to somebody else, have them commit the murder. They think if that guy pulls the trigger im clear. Reporter back in montana, thats what it seems Matthew Campbell was counting on when someone talked to friend bss taking out a hit on his mother. But again, a problem. Somebody felt that my brother was seriously contemplating doing this. That person went to the department of corrections and basically told on my brother. Hey, Matthew Campbell wants to hire somebody to kill his mother. Reporter thats all it took. An undercover fbi agent posing as a hit man approached matthew. Matthew is busted and sentenced to five years in federal prison. On the outside, dana and her daughters struggle to understand how this could have happened. Matthew tries to explain in letters home. This all blew up in my face. I cant handle it. I finally see where my lifestyle has gotten me. And i have been saved. In the name of jesus christ. All of this is cold, hard truth. And you dont have to believe it. But i hope you believe your son. Reporter over the last four years, letters like this kept coming. And with them, finally, a measure of forgiveness. The family now believes matthew never really intended to kill his mother and they are waiting for him to come home from prison this month. He wants to move on and put everything past him. And we do too. I think, yeah, were going to flourish into probably one of the best relationships i think ive ever had. Reporter hope springs eternal in big sky country.
