>> i asked danielle that very question. why are you saying this? and she just said, oh, i'm just trying to sound a tough. so she denied this to be for real. >> that that is not the way sam's sister saw it. when detectives showed those text to cindy she was dumbstruck. >> i could not believe what i was reading. this is someone who has been in my family for almost 13 years. even talking about it with you now, i have chills. >> those texts, she said, prove just how much danielle hated sam, and wanted him out of the way. she is convinced danielle manipulated michael to feel the same way. do you think that danielle had anything to do with your brother's death? was she somehow directly associated? >> i think she is. and i hope danielle but dreher i hold her as much if not more responsible than the man actually shot him. >> cindy told affective she believed hatred wasn't danielle 's only motive, that she was also driven by that age-old incentive -- >> i believe it was the money. to divorce him and split half of it is one thing. but to get all of it, i think it was money. i think it was always money. >> just over 1 million dollars in fact. >> it was a substantial amount of money that she was going to game if sam turned up dead. and that's exactly what happened. >> we asked danielle dreher to sit down with us for an interview. both she and her attorney declined. but during dreher danielle's interview the detectives she emphatically denied having anything to do with sam's murder. >> i would never kill my husband. i would never kill another human being. >> and the man who pulled the trigger supported danielle's claim of innocence. in no uncertain terms. >> i acted on my own. i did this all of my own. and, you know, i just -- >> so you are indicating, then, that danielle's only involvement was in order to help you -- basically, get dirt on her husband. to help in the divorce. nothing to do with harming him? >> right. >> but michael's response did not sway cindy lutz. >> i didn't believe him. i think he was protecting her. i think he would've done anything for her. >> cindy believe that included lying about danielle being involved in sam's murder. and cindy was an alone. >> do i believe that she was part of the murder scheme? yes. >> sarasota county lead homicide prosecutor karen fraivillig, believed danielle manipulated michael to kill sam. >> she's very manipulative person and she was able to manipulate michael minor. and there is a dead man because of that. >> but the question now before the prosecutor, could she prove it in court? >> coming up -- when one lover betray another? >> my hope is that he would contact us and say, hey, i want to tell you the truth. >> and the lover left behind ponders what might have been. >> we'll see the one?

>> i think that certainly, one of his motivations, if not his sole motivation was, trying to protect the woman that he loved. >> did you say to him, why are protecting her? >> yes. and he said, i'm not. he said i'm not protecting her. >> we were hoping that he would contact us through his lawyers and say, hey, i want to tell you the truth. i want to tell you what part she had in it. that never happened. >> two and a half years after shooting sam, michael minor agreed to plead guilty to second degree murder. >> and it will live with me forever and it will hurt me forever. >> and exchange for his plea, michael received a sentence of 30 years. >> i would not give him anything less than that. i mean, he pulled the trigger. he didn't pull it once, he pulled it four times. >> i was glad that he was going to jail. >> michael minor didn't just kill our brother. he has mortally wounded our entire family. >> michael minor never wavered in his statement that he acted alone. in the end, prosecutor fraivillig felt she didn't have enough evidence to charge danielle as michaels accomplice. >> i cannot just charge someone based upon my speculation's, the families beliefs, and even the ugliness of these text messages isn't off. unless i can show that there was a conspiracy. michael minor never gave me that information. >> what is your gut telling you? that daniel was indirectly involved? directly involved? or -- >> she wasn't >> had no part in this whatsoever. >> she wasn't involved in the homicide. >> news of the decision not to prosecute danielle for sam's murder made sam sister, cindy, furious. >> do i think it's a tough case, yes. absolutely. but you know what? their job is not to prosecute cases that are easy. their job is to prosecute criminals. >> but just when everyone thought danielle was free and clear, prosecutor fraivillig said, not so fast. remember michael minor's videotape breaking of dianne mcknight's apartment? the prosecutor believe daniel not only helped plan the break-in, she also instructed michael to steal some of dianne 's possessions. daniel was charged with burglary and theft. at trial, the defense argued daniel never asked michael to steal anything. the jury didn't agree. she was found guilty as charged and sentenced to three years in prison. >> this was a very satisfying verdict. to see the woman be punished for her actions. >> is the murder of sam with dreher an open case or close case? >> no, it's a close case. >> but not for cindy. who continues to mourn the loss of her brother. she keeps his uniform close by for comfort. and with it, a lifetime of memories. >> he was loving, he was carrying, he was the peacemaker. he was always doing for others. he was just sweet. >> cindy wants felt the same way about her sister-in-law, danielle. now there is bad blood between the two. cindy fought daniel in court over benefits from sam's life insurance. they ultimately reached a confidential settlement. cindy also keeps a watchful eye on danielle. according to cindy, daniel was dating another man before she went to prison. >> she was living with a firefighter with as a matter of fact. one of my brothers supposed fire brothers. >> what's your advice to this guy? this firefighter? >> watch your back. you know? the last two guys involved with daniel, one is dead, one is in prison. >> as for dianne, she's now left to reflect on a life with santa that could have been. did you to talk about marriage? >> yes. >> and was that in the cards? >> oh, absolutely. >> did you ever feel like i'm being punished for having the severe? >> oh, yes. i might have said those exact words to myself. >> it all started in a club, with an innocent conversation. was it all worth it? falling in love with sam? >> i would never change having met sam. >> was he the one? >> he was the one. without a doubt. he still is the one. >> that is all for this edition of dateline. i'm natalie morales. thanks for watching. >> hello. i'm andrea canning. and this is dateline. >> you can lose a child without knowing it in a second. it wasn't an if, it was a when. are they gonna tell us that she
