>> larry richmond jr is a 23-year-old evansville native. as a child, his time with his father was limited to prison visits, and now after years of being apart, junior and senior are reconnecting. >> so, larry jr., he's associated with a gun we think might be the murder weapon. that's a big step in the investigation. >> larry richmond sr. was taken in as well at the same time that mandy was, at the same time that larry richmond jr. was. >> well, larry, why we got everybody, it's not just you down here. obviously we are looking into the robert doerr situation -- he was gunned down in his driveway. >> what does that got to do with me? >> well, it has to do with everybody in the family, just trying to get everybody in here, see if there's just anything that could help us with this investigation. do you wish to talk to me without a lawyer present? >> i have no problem answering your questions. i will cooperate fully but due to my past, i have been incarcerated, i am on probation, i don't need any problems. >> sure, no, i understand.

>> so if i'm not under arrest, please get ahold of him. i'll come back down here and fully cooperate, no problems at all. >> all we're trying to do is find out if you guys know anything that could help us find this killer. >> i don't know nothing, we go out with them. we go out and drink. a u.s. outside of that there, i don't know nothing. >> so he understands what you should and shouldn't do when you get arrested by the police. so he's going to say, "no, i want the lawyer." and there's nothing wrong with that. >> with police unable to further question larry sr., he talk to his fiancee, mandy. her brother-in-law, robbie, is the victim. >> where were you at when robbie was murdered? >> i don't know exactly when it was, can you tell me when it was? >> last tuesday. around 7:00. >> i was home. >> you were home? >> were you home alone, where

your kids there? was larry there? >> yeah, we were all there. >> you were all there. >> kids, larry. >> hmm mmm. >> mandy says, he was with me the night of the murder. that's an alibi. >> so another weird question or another awkward question that we ask everybody, do you own a firearm? >> no. >> what about larry, does larry own one? >> no. not allowed. >> what about the gun that was found in the car? the officer found a gun in the car. >> when the police pulled over mandy and larry sr. earlier, they found a gun hidden in the car. now, it wasn't the murder weapon, but because of larry's prior conviction he's not allowed to possess a firearm. >> you didn't know there was a gun in the car? you all right? >> so, you pretty quickly understand that larry is now a suspect. >> yes. immediately. >> immediately. >> hey, mandy, do you know something that we don't?

>> i feel like i'm in the twilight zone. >> does it feel like a betrayal? >> this is what you watch on tv. you watch this happen to people on tv, not to your family. >> when they started to bring up this idea that larry richmond sr. may have been involved, i think that was a situation for her that was very eye-opening. and one of confusion because she knew about larry's past, and she knew that he was trying to become a better person, at least that's what he was expressing to her. >> mandy is clearly in shock but she's insistent that her fiance is not involved in robbie's death. >> i know he didn't have anything to do with this -- >> amanda fillmore was never a suspect. police spoke with her. they found her to be telling the truth about almost every detail of her life, including intimate details with her and larry richmond sr. and their relationship.

>> at this point, they had started connecting the dots that at least alluded to larry richmond sr. and larry richmond jr.'s involvement with respect to the stolen firearm. >> we have two more people down here now involved in this case. and one is your dad. and things aren't looking so good here. >> okay. >> what do you know about this gun? >> it came up missing the day of or a couple days before i started at the pawnshop. >> that's not true. i talked to the regional manager, i talked to the atf guys. that's not exactly the way it's gone down. the gun came up missing while you when you were an employee. >> yeah, while -- yeah, and i was sitting in the pawnshop. and somebody came up and said there was a gun outside, and then we called it in.

>> so larry jr. is there when it's missing. so now you know he's involved in this somehow. >> i got some bad news for you, son. i think you are heading down the same path as your dad is headed. >> for detectives, nothing is adding up. so, they make a drastic move, and descend upon the doerr family while they are saying their final goodbyes. so you watch as those four detectives take becky away for questioning? >> yes. the look on her face was just like stone. >> tell us what happened. how this all went down. but hisn dimmed with age. he had amd. i didn't know it then, but it can progress to ga, an advanced form of the disease. his struggle with vision loss from amd made me want to help you see warning signs of ga, like: hazy or blurred vision, so it's hard to see fine details, colors that appear dull or washed out, or trouble with low light that makes driving at night a real challenge.

at the funeral, police decided to question you again to pull you out? >> yeah, um, after we had taken robbie to the mausoleum, and i was taking some flowers or something out to the car. they came and -- and told me that they had a few more questions for me. >> in my head i was actually thinking, "well, this is pointless. they're just wasting their time. they need to get out there and do something else." but i'm thinking they got to touch all bases. >> becky arrives at the evansville police department. larry richmond sr., his son larry richmond jr., and her sister, mandy, are already there. >> so basically i wanted you to kinda, you know, take care of yourself, take care of your family. >> mm-hmm. >> and then bring you in here and go back, just hash through everything, every detail. >> okay. >> are. >> okay? >> you really want to know about her life and their lives together. what time did she expect him home? okay, what'd you do that day?

who called you that day? who'd you speak to? >> what kind of phone calls did they ask you about? >> what phone calls i had had that day, the day of rob's death. they also asked me what phone numbers were what. whose were certain phone numbers. >> well, the one we'd be interested obviously, is the one right before your husband was shot and killed. right? if you were in our shoes. >> well, yeah. >> okay. and that's this number here. do we know who this number is, right here? >> i don't recognize it. >> there's a reason why detectives are so focused on becky's phone activity. when they collected her cell phone originally, nothing looked suspicious. but they just received the raw data from her cell phone carrier. >> when you start looking at the extraction data, you're starting to see that maybe what we can't see with the naked eye is still there under the surface. one element that we saw that raised a lot of eyebrows was a deleted phone call from a contact known as larry ali.

about 15 minutes before the 911 call that robbie had been shot. >> i don't recall talking to someone like five minutes before rob was killed. >> i've been honest with you from the get-go. that's all i ask of you, is your honesty. >> and i understand that. i don't recall talking to someone like five minutes before rob was killed. i don't. >> they had information that she didn't have. and so at this point, they're asking her questions that they know the answers to. >> becky, don't get yourself into something that you can't get yourself out of, please -- >> i under -- i understand. >> -- by lying. okay. so take a deep breath and tell us who you talked to five minutes before your husband was killed in your driveway, getting out of his truck, in the back of the head. because i'm telling you, the federal investigation -- the fbi, we are looking into this as a federal crime. >> they keep pressing her, and

finally after 90 minutes of questioning, she comes clean. >> so who did you talk to five minutes before your husband was gunned down in the driveway? becky, we know the answer. so who was it? >> my sister's fiancé. >> the contact, larry ali, we would find out later is larry richmond sr. >> wait a second here. you spoke to larry sr. he just got out of jail 11 months ago for murder, and now your husband's dead. i mean, if you're not chasing that pathway, you're not doing your job. it's as simple as that. >> so what did you talk to him about? and do not lie, because we know his history. we know everything about him. >> i -- i don't know what, i mean, i know what happened to rob in my driveway. but i don't know who did it. i hon -- i -- i hon -- >> okay. >> i don't know. i -- i honestly don't know who did it. >> why are you lying? you didn't even tell us about the conversation. we -- we had to get to this point. >> she wasn't being forthcoming, especially for someone that just lost their husband, who would want the killer to be brought in and justice to be found. >> for becky, i think nobody can

prepare themselves to be accused of something they know they didn't do. >> i want the truth. >> rob told me that recently, the last time that we went out with larry and my sister mandy, that they had been talking about lights on the garage. and that larry would be coming out sometime soon to do a motion sensor. with -- with rob, though. the conversation, basically, was i -- i asked him about the motion sensor lights. >> and then three minutes later, puts five bullets in the back of your husband? come on! >> you understand why police were a little bit concerned when they saw that you had a call from a felon who had murdered somebody else and had just gotten out of prison for it. and that call happened minutes before your husband was gunned down in your driveway. >> i -- i understand where they were coming from.

but by the same token, i have a habit of erasing phone calls. i always have. >> and as soon as you get off the call with larry sr., you erase that call? >> i erase that call. >> who deletes phone calls? >> i do. >> why? >> because it takes up space in your phone. >> i don't think it does. i've never heard that before. >> but there's proof that i do. >> she deletes absolutely everything. and i know for a fact. if i were to send her, "i love you, mom," she would keep that and she would delete everything else. she will send the text message and then she will delete it. i don't know why. >> is that a normal thing around here, that people delete phone calls -- >> no. >> -- and messages? >> oh, no. i save every me -- like all of my messages -- i save. nobody i know does that. >> right. >> besides her. >> unless you have something to hide. >> exactly. >> why hold the conversation back from us that was simply about a sensor light? when this young man asked you how many times, "any more phone calls? any more phone calls?"

>> i didn't want you to think that i was having an affair with him, because i have not had an affair. >> i think becky's motive behind denying the call was to protect, not only herself, but her family. and more importantly, to protect the relationship that she adored with robbie. >> the truth is i didn't ask, or tell, or request anyone to kill my husband. did i know someone was going to kill him? no. did i want it to happen? no. i would rather me be hurt than robbie, and this is a nightmare. and i honestly, i'm scared to death, i don't know what to do, and that's the truth. >> after hours of interrogation, detectives say they can't find much else that connects becky and larry sr. to the crime other than that deleted phone call. but back home, a mysterious message awaits.

>> he called and said he found a card with a note in it. >> every step was shocking. and just when you thought you heard the most shocking part -- >> because in this family, bonds are broken. >> yeah. i called her, um, in a fit of anger, a murdering [ bleep ]. >> and hearts are broken. >> sisters don't do that to each other. ♪ ♪ have you always had trouble with your weight? same. discover the power of wegovy®. with wegovy®, i lost 35 pounds. and some lost over 46 pounds. and i'm keeping the weight off. i'm reducing my risk. wegovy® is the only weight-management medicine proven to reduce risk of major cardiovascular events

>> becky was arrested and charged with obstruction of justice, but she pleaded not guilty to those charges. so many are wondering, who committed the murder? meanwhile, during becky's lengthy interrogation, just a few rooms away, larry richmond jr. asks to speak with the detectives again. >> what's up, they said you wanted to talk to us. >> larry richmond jr. initially told them that he didn't know anything about that firearm. after doing that, it was clear that larry richmond jr. realized that they knew more than he thought they did. >> i don't know anything about the murder. but i did take the gun from my workplace. >> where is the gun now? >> probably at mandy's house. >> why would it be at mandy's house? >> because that's where my daddy put it. >> is that the gun? >> yes, sir. >> we took this from your phone. >> looking at larry richmond jr.'s phone, there is a string of text messages where larry richmond sr. continuously

asks larry richmond jr. about the peacemaker, which we would later discover was the nickname that larry richmond sr. had given to the taurus judge. >> the interrogators say "do you want to be like your father? do you want to go to jail for 22 years? do you want to miss your kids growing up just like your father did? it stops here, it stops now." and he's fully cooperative at that point. >> he said his father, larry richmond sr., had told him at some point, "if anything ever happens, i have firearms buried in the backyard." >> detectives head to mandy's house and dig up three firearms with the serial numbers scratched off. they even discover surveillance footage of larry sr. walking to the backyard, allegedly carrying this tote bag full of guns. but the taurus judge is not found. >> when my mom mandy was released, she was freaking out. her fiancé had buried guns that she knows he's not allowed to have in our backyard, which is where we buried our pet cat at some point. so, that was also not great.

committed the murder herself. but i think it started to make a little bit more sense that someone who's already been convicted of murder could do it again. >> your aunt mandy and larry, do you know anything about their relationship? >> i've only honestly met larry a handful of maybe five times. like thanksgiving, christmas. >> when you interact, i mean, what's his personality like? >> he's a bit standoffish. i can tell he's easily irritated. but it was definitely well known by his facial expressions that he was upset about something that was happening. >> becky, robbie, larry sr., and mandy used to go on double dates together. but now one of them is dead, two of them are in jail. detectives have already cleared mandy of involvement in the murder, but they need to speak with her again. >> let me ask you a question. what do you think is going on between larry and your sister? >> you're not the only one in his trick bag.

your hand?" she goes, "oh, nothing." i called her in a fit of anger, a murdering [ bleep ]. >> then, on the one-year anniversary of the murder, a surprise announcement. police name a person of interest in the case. >> 41-year-old evansville resident, larry ali richmond sr. richmond sr. had a relationship with the doerr family at the time robert was executed. >> richmond came on our radar back in march of last year, after police say that some guns were found buried outside of his home in his backyard. now, as we've reported, richmond was convicted of murder more than 20 years ago. >> authorities believe larry sr.'s cell phone could provide critical clues in the case, so they get a search warrant and seize it. >> i'm jon carter. i'm a criminal investigator with the high-tech crime unit out of the vanderburgh county prosecutor's office. in early 2021, we were provided with a device that belonged to larry richmond sr.

>> but there's a big problem here. police don't have the passcode to get into his phone. >> in this particular case, we applied the algorithm to the phone. >> the computers will literally run every possibility of passwords you can imagine. that takes a long time. >> in this case, it takes months. but then, they hit paydirt. >> one day, we came in, and a potential passcode had been found. i was calling everybody from the evansville police department, letting them know that we had found the passcode to the phone. >> investigators are finally able to get inside of larry richmond sr.'s phone to see what's inside of it. and what they said they find is pretty interesting. >> we were able to see his location data that put him near the scene of the crime at approximately 6:35 pm, approximately 20 minutes prior to the murder. we then had him traveling north, and turning his phone off at approximately 6:54 pm, and then

turning his phone back on at approximately 7:20 pm, near a gas station. >> during the course of our examination of the digital evidence, we discovered that larry richmond sr. was using a police scanner app. that's gonna raise a lot of questions that need answers. >> larry richmond sr. listens to the police scanner app both before and after the murder. >> we were able to see that he was looking at the news. there's a popular facebook site in evansville called evansville watch. he was reviewing that. and also, notably, he was looking at photos of robbie doerr. there were a lot of cached images that his phone was saving from robbie doerr's facebook. >> authorities recover a call log from larry sr.'s iphone that shows he allegedly made several calls to becky, in the weeks before robbie's murder. >> in larry richmond's case, his entire phone, he deleted almost everything in it. but we can see everything that's

also been deleted that hasn't been overwritten. so, december of 2018 to the murder date, they had twelve phone calls and some text messages. >> some of those calls only lasted seconds. if i answered, it was an answer and hung up. you know what i'm saying? 'cause i didn't realize that there was even that many. >> he is the fiancé of your sister, are you thinking that maybe he was in love with you? >> i never got the impression that he was interested. >> authorities get a tip from an inmate who, according to a police report, alleges larry sr. confirmed having an affair with becky, and more importantly, even claims that larry sr. confessed to killing robbie. what possible reason would he have to tell a cellmate, after he was arrested for the gun charges, that he murdered rob, and that he was having an affair with you? >> i don't have an answer for that, because that never happened. >> do you think his cellmate was lying about it? >> he had to have been. i don't have an -- i -- i mean,

i can't tell you something i don't know. >> so, things that were happening point closer and closer to larry richmond sr. being the person that we need to be looking at. >> three years after robbie's murder, evansville authorities finally make their move. >> a short while ago, larry richmond sr. and elizabeth fox-doerr were charged with the murder of robbie. >> larry richmond sr. and becky were charged with murder and conspiracy to commit murder. they pled not guilty to all the charges. >> when they finally told me they were going to charge both of them with murder, i was like, "all right, let's go, we've got this." >> they believe that she was part of the murder. at the time i was thinking, they've got it all wrong, they're wasting their time. >> what the prosecution is saying is that you conspired with your sister's fiancé to murder your husband. >> but i didn't. >> right. >> court tv's newest case.

>> so, we're now at becky's trial. but because she is charged with conspiracy to commit murder, the jury is hearing a lot about larry richmond sr., who has his own separate trial scheduled for next year. >> larry richmond is not literally on trial here, but in a sense he is, because to prove there was a conspiracy and that she conspired with him to have her husband killed, we have to show that he did in fact kill her husband. >> you won't hear one piece of evidence that says they were lovers. that's speculation and supposition. there is no evidence that becky doerr knowingly or intentionally aided, induced, or caused larry richmond sr. to commit the offense of murder. that evidence doesn't exist. >> their actions were very much linked. and that's what makes it a conspiracy case. >> essentially, what police and prosecution were saying is that you didn't pull the trigger -- >> right. >> -- to kill robbie, but, you set it all up. >> no. i had nothing to do with it.

nothing at all. >> a guard at the jail where becky and larry were held before trial tells of a mysterious note attached to, of all things, a packet of ramen noodles, and addressed to someone named "barbie." in prison slang, this is called a "kite." >> inmates will tape kites to the top of ramen noodle packs, and they'll give them to laundry workers, pretty much as payment to pass it on. >> the inmate workers find the packet with the note attached to it and immediately give this to their supervisor, who's a correctional officer. >> i ask that the witness be allowed to read exhibit 91 to the jury. >> "hello barbie, just wanted to drop you a line or two. they will bring plea after plea. don't fall for it. keep your head up and go to trial." >> he calls her barbie, and then at the end, signs it, "you know who." and he's talking about not
