says his brother, who he describes as having the mind of a child, looked up to their father, and would do anything for him. >> he is going to do anything and everything he has to do to make sure my father is innocent, >> but if his father loved randy jr. back, why would he get him involved in the crime in the first place? even go a step further, but let his own son take the rap for it? >> my son is already caught, so i won't go to jail. >> shawn says he was more than disgusted. he loved his brother, and had been protecting him since they were young. now randy jr. needed protection and more than ever. shawn felt it required him to turn in his own father, for a crime of which he was not even suspected. >> he went there, to kill him. >> shawn says the murderous scheme was set into motion, when is dad received a letter from joe morrissey. it informed him that he owed just over 1600 dollars, and his

beliefs would now be month to month. that letter arrived the day of joe's murder. >> how did your dad react to that letter? >> like, i'm not even going to do? it >> it was an insult to him? >> he took it like, that it really was not. it was a man, wanting his money. >> but your dad saw it as provocation? >> like, i'm going to teach him a lesson? >> right. >> his dad then roped in randy jr.. >> my brother did not know who is how c was going to. my brother did not know someone was supposed to die there. >> only to turn his back on him afterward, and let randy jr. fall under suspicion for the murder. >> he says, they caught him, not me. i said, you fixed it, so i will. >> that's what you said to your? farther >> straight up. >> fix this, or i will? >> yes. >> that is when shawn turned his back on his father, and went to police, trying to save his brother, by informing on his dad. if that didn't stunned the

officers, then what shawn did next did. >> before we could even ask him to wear a wire, he offers to wear a wire. he wants his father to be held responsible for this. >> ever seen anything like that before? >> no. >> the sun was going to become a police informant, where a wire and try to get his own father to admit to a murder. the sound quality on the wire is poor, but for police, shawn randy sr.'s guilt came through loud and clear. >> what part of that conversation says to you, guilty, we got him? >> i think that when he tells shawn that we have no case, our case is weak. he tells shawn, she can't identify me, she can't even identify randy. putting himself there. >> what's more, this security video from the business next door to randy sr.'s shop shows

randy tundidor sr. and his son randy jr. were both charged with murdering joe morrissey. but a second son, shawn, told detectives jr. was an unwitting accomplice. each shawn claimed his father was the mastermind mastermind behind the crime. now father and son were about to face trial.

a tragic tale of two contrasting families was nearing its bitter and. here's josh mankiewicz with the conclusion of "broken bonds". >> on a quiet april night in florida, intruders had invaded the home of kay and jill morrissey, and committed unthinkable crimes. the were >> the worst-case scenario you can imagine. you're living your life you with the way you think you're supposed to, and evil just walks in and rips your life apart. >> tom coleman and stephen zach or prosecute the case against randy tundidor sr. and his son randy jr.. there >> there are no thought circumstances you could look and say maybe if it had gone differently, it would've had a different result. there is nothing more the morrissey causative done that could've prevented this other than never meet the tundidor. >> but these two families did intersect with disastrous results. all prosecutor say, because a tenant got angry at a landlord.

>> who was this little scientists to think he's going to mess with me? and no one was going to mess with his family. and i was going to take care of it. that's what this was. >> but in the end, randy tundidor didn't seem to care about his family. >> in fact, prosecutors say he tried to play in the blame on his son, randy jr.. >> the phone calls to detective kendall about tests this shirt for dna. that's your killer. let me just piling on him. it just trying to get himself out of trouble trouble. >> randy jr. won't give him up. >> nope. doesn't give him up? >> randy sr. sr. jr. stuck by his dad. even though his father pretty much threw him under the bus as soon as he came under suspicion. >> and never stopped. back to that bus air over every time we. good >> so the sun is lawyer loyal to the father, but the sun is not loyal to the -- >> absolutely. >> prosecutors thought it might be a tough case against randy sr.. but then something surprising happen. after swearing to police that his dad was not in any way

involved, randy jr. took a deal. and agreed to testify against his father. as it did shawn. but randy sr.'s trial was head to help two years after duels murder. he faced the death penalty. kay desperately want to make sure he received it. and her testimony in court was powerful. >> i was like, scared. he never answered me. >> on the stand, randy jr. told the jury how his dad intended to inflict even more harm on the morrissey family. >> he wanted to kill miss morrissey and her son. he said, they got to go to. i told them no. i just told him i can't do that. >> can't do? >> i can't kill a kid and the mom. >> randy sr.'s primary defense

was that he was not involved. the father went far beyond that. >> we went to trial and he buried both of his sons. at or he try to. >> because it wasn't just jr. on trial. it was that shawn was the other person in involved. it was sean trying to steal my business. he can't ever accept responsibility for anything. >> in court randy jr. lashed out at his father. >> the fact that he was sit here and say that it was me and my brother who did this and plan this, i feel like that's wrong. you shouldn't do anything to hurt your kids. i think that a father's job is to protect his kids, not to hurt his kids. >> after five and a half hours of deliberation -- >> the defendant is guilty of first degree murder. >> the jury convicted randy sr. on all charges. >> when they say guilty, i felt my heart -- i couldn't breathe. i was very overwhelmed. >> the jury later voted unanimously to give randy sr.

the death penalty. the judge agreed. luckily the florida supreme court ruled that randy sr.'s convictions for attempted first degree murder and attempted felony murder amounted to double jeopardy. the attempted felony murder convictions were thrown out. but his conviction for first degree murder and his death sentence remain in place. randy jr., who pleaded guilty to second degree murder and cooperated with prosecutors, was sentenced to four years in prison. kay morrissey is angry about that. >> i believe that the crime would would've happen one without the other one. they both deserve the death penalty. >> kay morrissey says she's not imprisoned by fear. instead she says the nightmare has made her fear less. she even sent a letter to randy sr. seeing as much. >> you're a coward and i'm not afraid of you? but >> yes. >> i am never leaving and will

always be here. so you're saying, coming get me? >> right. >> tough guy? >> yes. >> i'm not going going to be fearful. i mean, they attacked us in our house, which is your safest place to be. so i started to become extremely fearless. >> she's also struggled to put her life back together. kay but's daughter says she can see the pain even as her mom holes patrick close. >> it's hard to watch my mom with patrick, because you can tell they miss him. and they should have been. they shouldn't have to figure it out without him. >> they still have each other. i >> believe god has a plan for us. and that's why we survived. >> and she has many memories of her dear joe. after he died, kay wrote about it and to him in a letter. >> joe, i know we will see each other again. in the meantime, please watch over our children and to protect them from harm.

joe, i think you for being such a great, loving husband and loving father. i love you so much. i love you forever. >> that's all for this edition of dateline. i'm craig melvin. thank you for watching. first up on msnbc. confronting our adversaries. president biden preparing for his first foreign trip. and vowing to take on vladimir putin over the recent ransomware hacks, increasingly impacting americans daily lives. the senate sergeant at arms now warning she's more worried about a cyber attack against congress and another insurrection. >> donald trump picking up right where he left off. the big lie is the focus for the republican fund-raiser late last night. and liz cheney slamming him as a very real an
