Everything looked like it was going good. Then she fell asleep last night. Could I describe Grace as an ex-girlfriend? Would that be an accurate way to describe her? Okay. So, Grace contacted you yesterday. Kiera also has a past with Grace. So, they know each other? Yes. What's their past? Uh they are exes to each other. Oh, they used to date each other? Yes. Okay. How long ago was that? 2017. Now, the interview turns to the events of the previous night. I walk in to Kiera and she tells me against me that she Oh, Kiera goes, "I did it." I look at the girl and I see someone dead. I see an ear hanging. And I'm like You see someone dead. Who was that someone? Grace. How do you know she's dead? Cuz she Cuz Kiera goes, "I got her across the throat." And then she did the verbal. And I'm like I don't know what to do now. I need to get out of here. You don't like Kiera did this? No. What were Kiera and Grace doing before you went to the restroom? They were just sitting there. Wait, did you help Kiara injure Grace or do anything to Grace? No. He denies any involvement in the crime. But when he allows police to look at his phone, his involvement in the crime becomes more clear. This is at 11:56 a.m. What? And that's that's uh forgive me, I forgot her name for a second. This is your fiancée saying this? What? Yes. Here, I have a plan with what I said. All I have to do is be over there at my fam's place and call the cops for a breaking and entering. What are you talking about there? Um [clears throat] it was something that happened at my family's house, so we've been trying to figure out who has been getting into my uh storage. Mhm. I have stuff in my storage and they keep finding it unlocked. And that was something entirely different. Hold up, listen. Okay, plan B. Just tell her she needs to leave. Follow my lead, my lady. Just tell her to leave, dude. I'm in a mood. I did. Through Insta. So, now what? Operation kick out me following the call to the cops once I'm at my family's. What does that mean? That was um I was talking about cuz she had asked me to leave. And that's why I said operation kick out cuz every time I get told to leave, I say operation kick out. Cuz it's her go-to thing to tell me to leave. And it's like she kicks me out and then a few minutes few days later she'll then come back over and stuff like that. But to call the cops at my family was because of the breaking and entering. >> So, according to you, you're talking about three different things at the same time. Yes. Okay. How about I just explain why I'm angry and why she's not wanted. Okay? Show me what you sent her. My plan. Okay. Well, and those are the messages that we looked at earlier between you and Yes. >> Okay. It worked with Christian. She says she's leaving at 3:30. She's mad. 3:30. But buried in those messages was evidence of something far more sinister, a calculated plan to commit murder. As the detective reads further, a grizzly plot starts to emerge. >> Yeah, why don't you pop off, my little firecracker? What would you like me to do? Stab her. I don't know. I don't have the energy to do sh What's this? Read what she sent. Is she stupid? Yes. Okay. I am fake getting thrown out. I am fake getting thrown out. You're getting fake thrown out. Yes. That's usually how it happens is I get told to leave. Mhm. And then five days later she asks me to come back. Her mother is her backup ride. Okay. Want me to get your mom to give me a ride to Target so you can take my stuff into the back room and her mom and your mom don't get into it. Yay or nay? Wait a bit, though. Okay, how long? Until there's a clue on when she's leaving. She admitted to me when she lived at those apartments and she was sober then. She admitted to me also back when I first met her calling you crazy. What are you talking about? I don't know. That's not me. That's not you? That's not me. Who is it? That's the other phone that's been they've they were being used to message back and forth. Isaac, this is getting really weird, man. I have a second phone. You have a second phone? Yes. >> Where is that phone? That's at the house. So, Kiara had interest in Grace. Kiara was going to do something. And how did How did you feel about that? I did not want to be a part of it. But that's your fiancée, right? I didn't want to be a part of it and I had already told her I told her in person saying I don't want to be a part of anything you have to do if you want to move on forward with the anything you do now. But you invited Grace over there? Yes. Okay. Hey, can I come back? I don't know, can you? Yes. Dagger because it's blunt. What does that mean? Um Why are you telling her dagger because it's blunt? She was ask She asked me a question in the room like, what what is the difference between the dagger and the sword? Okay. And I messaged dagger because it's Why is blunt better? She says you say it cuts like butter. She says just going to stab the >> [clears throat] >> throat? Is that what she's trying to say? The throat. Just going to stab the throat. Yes. Instant or will it take long? What does she mean? Instant. What do we do about the mess? What do we do about the mess? What mess? We burn it and I'll buy new blankets and bed. What's going on here, Isaac? She I was talking to her and What mess? She was talking about she said stab just going to stab the throat and I thought throat like um she was poking the thought that was in her head about her dagger. Okay, what about the mess? What mess? Uh she had made a mess in the in the bed. What kind of mess? A poop kind of mess. A poop kind of mess? Yes. We burn it and I'll buy new blankets and bed. Yeah. But until we can, I love these sheets and my favorite fuzzy blanket is here. I know. Just intense wash tomorrow. Hydrogen peroxide and ice. Washer will get it out. Yes. Can you help this time? Yes. I am just waiting for you to make the first move. What does she mean I'm waiting for you to make the first move? She will wait till sleep. Shall we wait till sleep? She pooped herself last night? Yes. And did you guys wash the sheets? No. So, you guys slept in a bed full of poop? Yes. So, when we go to the garage later for a search warrant, there's poop on the sheets? Yes. Okay. Got you.

We will have to take care of the mess ASAP after we finish. We will have to take care of the mess. I thought she already pooped herself. What mess you guys taking care of? I don't know. Okay. Cuz I was trying to go on about remember when you told me don't be when I kissed you. I was trying to um tell her that tell bring up something that was a good memory. Yes, you're in charge of cleanup. Okay. I can't talk, she's falling asleep. It feels like it. Her feet are on my side. I wish you'd make the first move for once. Remember, you'll move up the ranks plus you get perks in the black market since this is your first. Your first what? She >> Isaac, what the hell happened? Tell me what happened, for real. Can we stop making up lies about these messages? What the hell happened last night? She was messaging me on planning on how to kill her. And Who was messaging you planning on how to kill who? Kiara. Kiara was messaging you on how planning how to kill Grace. Grace? Yes. And what were you doing? I was only sending a message back. Only in correspondence. I just wanted to sleep. That's what I was >> Are you sure cuz it sounds like you're planning something with Kiara. Is that what's happening? Don't lie to me. What's happening here? I can see the messages. I'm not dumb. This isn't the first time I've done this. What is happening? She was planning on killing Grace. I just didn't want to be a part of it. It doesn't seem like you're trying to talk her out of it. And when it comes to this stuff as I'm as I'm talking telling you, she I was only sending a message back in agreements as I turned my back towards This isn't agreements. Remember, you'll move up in ranks plus you get perks in the black market since this is your first. This sounds like you're encouraging her. The messages are here, dude. I know. I I know. Right after that I was trying to fall asleep cuz I didn't want to be a part of anything. When did this plan start? Cuz this was planned. She planned it out. Grace planned it out? >> No, not Grace. Kiara planned it out. >> Kiara planned it out. When? How long has this been a plan for? She had planned it out since 2020. Kiara planned to kill Grace since 2020? Yes. >> And you knew about it since 2020? Yes, and I had been to going to counseling because of that because of this. Okay. And then last night Grace messages you looking for a place to stay. And that's the opportunity for this? I didn't see it as an opportunity. I saw it as an opportunity more like let's squash it, I think. Then why are you saying that you'll make it up the ranks plus your perks in the black market since this is your first? Cuz you're talking about killing her here, right? I was What else could this mean? Remember, you'll move up in the ranks plus you get perks in the black market since this is your first. What else would you be talking about here? I was trying to talk about something else cuz I'm trying to get my mind off Isaac, really? You're trying to talk about something else there? Yes. And I'm not How do I aim? How do I aim right? Just aim. Well, tell me what you're talking about there. That's Call of Duty. That's Call of Duty. Tell me when. Okay, I'll give a count. 6 5 I can't yet do. 4 I'm shaking, dude. I know. I lose the nervous. Help me drive it through. Help me drive it through. What do you mean help me drive it through? She was asking me to do to stab her. Yes, and I didn't want to do any She was asking help me drive what? The sword, the dagger, the butterfly knife, what? >> The dagger. >> [clears throat] >> Help me drive the dagger through Grace. The detective now realizes that Isaac was egging Kiera on, but he continues to deny any involvement. What you say here is I am saying just swing and don't regret the aim. So, tell me tell me what that means. Just swing and don't regret the aim. It was me telling her if she was going to do something, she should do it and I didn't want I didn't want to be a part of it. I have my I had all my stuff What is holding you back? Type it. You're egging her to do this. Come on, Isaac. Isaac. Look at all these messages, man. You're going to sit here and tell me you're going to look me in the eye and you're going to tell me that you were trying to talk her out of this. I can see right here you're telling her to do it. What the hell happened last night, man? Why did you want her to do this? I didn't want her to do this. >> Why are you pushing her to do this? I was trying to as the messages are going through, she kept coming back and forth to talk to me and the messages were going through and I was just like I had enough. I'm done. Like Hope love bull You say, "Well, at what percentage are they?" She says, "I don't know." You say you still love her. You have hope in her and you tired of the bull she put you through. She says, "I want to break her heart." Tell me what happened then. Clear your conscience. What happened? Don't think about it. Just put it all out there. Tell me what happened. You'll feel better. I'm not thinking. It's just I was asked to help quite a bit in those messages. That's you, right? And I didn't want to help. I didn't want to help. I didn't want to help. Simple fact that it was my friend. So, I had found I was trying to find a possible alternative to get her out of there to safety. And that was when I called my friend Chris and Chris they were right in the neighborhood. Mhm. >> [clears throat] >> And they were like, "Well, let's get a let's get the area set up for her to move over." And [snorts] after that I started sending message I sent some messages back to make it sound like I was doing something stupid, but I didn't I didn't plan on telling it to happen. Well, what about all the messages where you're clearly egging her on? You're And you could tell me you're talking about something else. You're referencing movies. I don't The one is actually a reference to movies. >> Cool. That's the only one that I'm going to say here. Let's get We'll give you that. We'll give you the benefit of the doubt on that one. But all the other ones that you're saying you you meant something else, come on. Isaac, come on. You know you were talking about something else, right? Yes. You know you were. So, if you're going to sit here and tell me that you didn't you didn't want this to happen, that you were trying to talk her out of it, push her away from it, the messages don't say that, man. It's over, Isaac. It's over. Look at me. Look at me. It's over, dude. It's over. The focus now shifts to interviewing Kiera. She claims to remember nothing at the time of the murder but is not afraid to share her feelings about the victim. >> Well, I'm partially hopeful for her to be dead, but I'm also like confused. Like was I'm like Why would you hope that she's dead? Uh I'm just angry at her. Honest. I like honest people. I don't want to lie. Um have you ever thought about hurting her or killing her? I thought I had a couple dreams like that. You had a couple dreams like that? Yeah. Did you kill her in those dreams or what happened in those dreams? Sometimes I would kill her, sometimes I would torture her, sometimes it was just me screaming at her. Were you uh were you talking to Isaac last night? Were you guys messaging each other and I was trying to tell him to get her to leave. Did you guys say anything else? I just wanted her gone. So, I was talking to Isaac for a long time earlier before you and um we're going through his phone. He had his phone on it. There was a lot of messages between you two. Yeah. What were all these about? You know what I'm talking about, right? Yeah. It's like in this kind of lobby area. I can't really remember. Yeah. And so and this is kind of me trying to piece together kind of like what you were saying like the messages I saw too was Isaac trying to push you to kill Grace? Yeah. Um and I I had my dagger in my hand and I took like and then just stopped like I felt a little kid's hand hold me back. Like it was Kiera telling me, "Don't. Don't." "Don't. Cuz that was also her best friend's sister. So, yeah. Yeah. And when I did try when Isaac kept telling me to just do it and then I and then just it literally feels like somebody's holding felt like it was somebody was holding me. So, when you're kind of demonstrating right now, was that you about to stab Grace? Yeah. Was she asleep? Yeah. At least I think she was. She looked passed out. But it just [clears throat] kept stopping me. Do you think you killed Grace? I'm not sure. She is dead. That's the dead person found in the garage. Do you have any memory of that? You said you got that. Just like Yeah. I'm trying to process this properly. This is like confusing. Like I don't know. Do you think it's possible you killed her? I'm guessing myself right now. I'm second guessing trying to figure out. I think you're you've been very honest with me. I don't have any I respect the hell out of that. I'd like to return that to you. There's probably a good potential that both you and Isaac will do jail tonight. You understand that? Yeah. Kiera pleaded guilty to aggravated second degree murder and conspiracy to commit murder. She agreed to testify against Isaac in exchange for a deal. Isaac is charged with first degree murder. His trial is set to begin in June 2026. Please keep Grace's family in your prayers.
