Um A lot of anger going on right now to be completely honest with you. Yeah, that's that's all I really have to say to you at this point. I yeah. >> Okay. >> There's a lot of mutual mutual anger, mutual hatred going on right now. Um >> Okay.

Um and then there's just been like a constant like distrust of like anything that I do, anything that he does type of a thing. >> Okay. >> Cuz there has been you know, things that have happened in the past and so we just haven't there's been no trust. So no matter what I do, no matter what he do does, there's no there's no trust on either end. If that makes sense. >> It does. >> That's a hard place to be in a marriage. >> Yeah. >> Yeah, okay. Where do you foresee yourself going from here with him? >> Um for for me, myself, and for my son, um it's not a it's not a place I want my son to be in. What I would like to be the divorce is definitely what needs to happen at this point. Um >> While Garrett presents Snapchat screenshots as evidence, McKenzie's initial defense focuses on her failing marriage. Notice how she framed the conflict around mutual infidelity and mistrust rather than directly addressing the allegations. >> Um It's gotten really bad. Um Yeah. >> Okay. >> To the point where like I I love him dearly. I really do in my heart I do. >> Sure. >> And I want my son to have his dad in whatever capacity that is. >> Okay. >> But him and I together is not is not a It's not a thing that should happen. >> Okay. That's fair. You can both love a kid together and not have to love each other all the time. Okay. Okay. What's What tonight that caused him to be so upset and feel the need to call us? >> Um so we we have friends over. Um one friend that is a really dear friend to me and we we're kind of [snorts] opening up and talking about it like they were talking about their relationship and things like that and um it just kind of escalated and then um him and the hus- other husband left to go to the bar and we were here chatting and then he just came back really escalated. >> [clears throat] >> Okay. >> And just kind of started coming at me questioning things um and it just it just spiraled. >> Okay. What was he questioning you about? >> Um cheating on him. >> Okay. >> Mhm. >> Have you been? It sounds like it goes both ways but have you been recently? >> Um not recently. No, I have in the past but not recently. No. >> Okay. Okay. What was What were you >> the past there's nothing been anything physical on my part. >> All right. Emotional cheating. >> Yeah. >> Okay. >> Yeah. >> What was he accusing you of tonight? >> Um he was accusing me of being with another individual in the area. >> Okay. >> Yeah. >> So he told us that you told him that that happened. >> No. >> Okay. >> No. >> Why would he tell me that that you had sex with another person? I mean cheating's not a crime but >> No. >> he's just upset and wants you not to be here. >> I Yeah, I think there's a lot of upset feelings. I think there's a lot of hatred going on right now if I'm going to be honest [snorts] with you. Yeah. And I think I don't know about you but when you're mad about something, I think you would do anything in your power kind of to um make it not only make yourself believe that, but make that other person feel like they should feel like that, too. >> Okay. Okay. I just um it's really unfortunate, to be honest with you. There's a 3-year-old little boy upstairs that's involved in the situation, and it's really unfortunate. >> Okay. >> There's another kid sleeping down here. >> Yes. >> Is that with your friend's kid? Yeah. >> Okay. Okay. >> [snorts] >> Um Okay. You said you see divorces in your future. >> Mhm. >> Okay. Um He said you guys were arguing tonight over Tell me about him. >> Um he's a boy that goes to school here. Um he's a very uh flirtatious boy with any individual he encounters. Um There's been accusations of him and other teachers at the school. So, there's there's that at play, as well. And I think there's that's where that comes from. >> Okay. What was your guys' conversation tonight? >> Like he had left to go to the bar, and he had just stated that he thought that there was something that had happened there. >> Okay. Okay. Tell me about the messages, the Snapchat messages with >> Um so, to be completely honest with you, there was a situation in St. John at Taco Drama, where my husband had supplied alcohol to this individual person. >> Okay. >> Um that I was not okay with. And I just >> Okay. >> And I had reached out to him to confirm that, because I saw him have a beer that I saw my husband hand him. >> Okay. >> Remind me when Taco Drama is. It's been a while it's been Mhm. Trying to remember. Couple months ago. Couple months back. >> Okay. >> Um so, I was trying to figure out that what was was what was going on, cuz like [snorts] I said, there is a there's a chronic alcohol issue there. Um there's a with Garrett. >> Mhm. >> Okay. >> Waking up, he's not here. Waking up he is here but he's passed out on the couch. A lot of that happening. So I wanted to confirm that accusation but also be like what the heck type of a deal. And I think that got taken way out of context especially when there's a trust issue at play. >> Okay. Okay. And so in those messages it sounds like you guys are trying to meet up. >> Mhm. To confirm that resolution. >> That he's not supposed to be drinking? >> Um that my husband was or was not supplying him that evening. >> Okay. Why would he say that I think this is a bad idea to meet up with you? >> Uh probably because he knows that he's going to be coming to my house and who's at my house. >> Who's at your house? >> My husband. >> Why would that be a problem if your husband's supplying him the alcohol? Your husband's not going to get mad at him. >> But if he if he doesn't know that I'm talking to him. Like he wouldn't want me to he's not he doesn't want me to be upset about it, right? >> I'm confused. >> Is he am I okay with it? No. >> Okay. >> Right. Is he does he think it's okay? Yes. >> Right. So you guys are in conflict over that but it's not your kid. >> It's not my kid but that's that's that's my reasoning. That's my reasoning behind the whole thing. >> Okay. Do you have your email on your phone? Um Okay. And this conversation happened after Taco Trauma? >> Yeah. >> [snorts] >> What does it mean when you send him a uh photo of you in bed? Saying, "Is that your way of saying you will stay for me?" What does that mean? >> Um to be completely honest with you, I was very intoxicated at that point and I I don't I don't not recollect that. I don't have any recollection of that. >> That you? >> Mhm. >> Okay. >> I don't have any recollection of that. >> Okay. >> [snorts] >> So, when you're trying to meet up with him, you're trying to meet up with him to confirm that he's been having alcohol that he shouldn't have. Right? >> Given by your husband. >> Yeah. Mhm. >> Which you don't approve of. >> Mhm. >> Okay. Um Oh, you're so tough. Yes, you are. That's your mama. Why are you barking at her? Hi. She's fine. Um >> As McKinsey insists nothing physical happened, officers head back outside to verify the details. But a third-party witness is about to change the direction of this entire investigation. Stay tuned for part two.
