911. >> Um, my neighbor just came running down the road yelling, "Call 911 for gunfest, too, please. I think my parents were shot upstairs." >> You think your parents were shot upstairs? >> Yes. >> Have you been upstairs to check? >> No, we just ran. Police Department. >> Police. >> Unsure whether they were walking into an active ambush, police entered the home. >> Washington State Police. >> Inside, they discovered a tragic scene. Husband and wife Joseph and Gail Bailey [music] had suffered fatal gunshot wounds. But after clearing the house, the shooter is nowhere to be found. >> [music] >> Tensions are high as police know the killer could still be nearby hiding an ambush. [music] Then a report comes over the radio that an unidentified male was seen running into a neighbor's house. >> In your basement just right here, >> we got a neighbor saying there's a male who ran into his basement. He doesn't know who he is. >> The man hiding in the basement is Joseph and Gail's son, Corey Bailey. Cory and his wife were inside the house during the shooting, but were able to escape through a window. As they hide inside their neighbor's basement closet, Cory speaks with 911. >> Tell me exactly what happened. >> We were downstairs and I started hearing gunshots and screaming upstairs. >> Did someone come into your house to shoot? >> Yes, I think it was my brother. >> Do you feel like it's safe to go check on your parents? >> No. >> Okay. So, we ran into my neighbor's basement and stuff cuz we're hold out in the closet. I don't think they even know we're here. So, >> sounds like they're on the phone with 911. They're afraid. They're downstairs. >> Come outside. Police department. Come outside with your hands up. Let's get cover back here. >> If you're in the basement, step outside. >> See what I don't understand why they would come down here and lock themselves in. >> Yeah. >> Come outside with your hands out. I got contact with the mail. come outside with your hands up. They got their hands up. He's All right, sir. Are you Cory? Yes. >> Okay. I'm just going to pat you down real quick. Okay. So, this is son, not uh not our suspect. We're looking for uh Colin. >> Yeah. >> Colin. Okay. >> Colin is Cory's sibling, but now goes by Mia after filing a name and gender change in court one year ago. You'll hear Cory still use the name Colin, while other family members use Mia. >> Any idea where he'd be headed now? He started pounding on our door as soon as we were going out the window. So, I have no idea. I don't even know how he got here. >> So, he doesn't live here. >> He has a protective order against him already. >> I'm sorry to be the one to tell you. I >> I don't think >> they're they're deceased, both of them. >> Okay. I'm going to let you deal with that. Okay. >> Okay. >> Do you need something right now? I mean, we have a victim's advocate we can call out for you. >> I I don't even know where to begin with this. >> Oh, I know. >> Until he's found, I don't know where to go that we'll be safe >> at this point. Cory, how long go to this halfway? >> Like 20 minutes ago at Pops. >> That's why I had a protective order against him so he couldn't get a gun. >> So Cory, I know this is hardest thing you've ever done, right? I need you to tell me what happened today. >> So me and my wife were downstairs. >> Uhhuh. >> Watching a show guy. All I know is I heard shooting upstairs and then my my mother yelling and screaming and then I locked the door to our room and I started opening the window and I tried got her out and got myself out. By the time we were climbing out the window, he was pounding on my door trying to open it and then I heard gunshots at my door there. So I think he was trying to shoot the door open or something like that or try to shoot in where we were. >> He's a schizophrenic. He's been going through a lot of issues lately and trans transitioning. >> Apparently, he was supposed to do some surgery or so. I have I haven't been keeping up on what's going on with him too much, but it got cancelled and he thinks it was their fault. So, >> uh, what does he drive? >> He drives a yellow Kia Soul. >> We're looking for him. >> We're never going to be safe. How we going to go to work if you can't be anywhere? Is there any place we can stay? Don't think I want to take fighting somewhere. >> I knew he was going to do something like that one day. >> For 2 days, southern Utah was on edge. With an armed suspect on the loose, residents were urged to stay alert and shelter in place while deputies [music] began questioning neighbors and family. >> Do you by chance have any cameras on the outside of your home? Nothing. No doorbell cameras? Nothing? >> No. Everyone okay? >> Yeah. Can I just get your your name real quick? >> See if we can get a look at your cameras. They're not on. And this is a quiet road. So >> until something like this happens, >> she wasn't acting super crazy or upset. Anything that would make you concerned that something like this was going to happen? >> No, she seemed perfectly normal. No idea where she got a gun. She's always been very docile around us. You know, she doesn't have the things with us she had with her parents. This is just a absolute stunner to me. When police spoke with Mia's griefstricken 92-year-old grandma, she believed Mia wasn't even still alive. Is >> my daughter gone? >> Sorry for lost. >> At age 92, I shouldn't have lost three children. >> The only clue police had was a telematic alarm triggered on a highway. >> Hello, can you hear me? This is 911. >> The owner of this iPhone was in a severe car crash and is not responding [music] to their phone. >> It came from Mia's pink iPhone smashed in the middle of the road. Hello, this is 911. >> This message will repeat in 5 seconds. >> With police unable to trace Mia's phone location, they continued speaking with witnesses. [music] >> Washington City Police. If anybody's in here, let yourself be known. >> So, I just want to find out what you saw, what you heard. >> Okay. So, I was sitting on the front and I just heard like, "Call the police. Call the police." >> Yeah. Like, how's she been the last few days? Like, >> delusional, paranoid, mentally ill. I mean, I can't put it any more Frank than her. And I've known her my entire life, and she's never She's been autistic her whole life, right? >> She's autistic. >> Yes. Very. But these delusions, the paranoia, the they're putting radiation in my food, their microphones in the walls type [ __ ] is all new. >> You know, if she's been on any substance abuse issues or anything like that? >> No. No, she is not. I can tell you for a fact she's not on any drugs. She doesn't like drugs. I couldn't get her to do them if I wanted to, you know, type thing. >> Okay. Um >> she's taking I mean massive amounts of hormones for her um transition. She's on estrogen on tester testosterone blockers. That's got to affect your mind in some way and it probably did not good things to her brain. You know, like she's she's clinically insane at this moment. You know, >> there was two outside shots, but the last two I was like, "Oh, those are gunshots." Like pop. That was very clear to me. Okay, >> please hear the police. >> Yes. >> Can we see some ID? >> Hold on. I got one for you. >> That's okay. [music] I heard what was going on and I'm quite frightened. >> Oh, absolutely. >> I was quite frightened. I thought it was a person coming after us. >> Are you aware of why we're meeting trying to find her? >> That she might have killed somebody. >> So, obviously very concerning, right? >> Yeah. [snorts] >> Yes. So obviously don't answer your doors, right? Like you did. >> The panic wasn't contained to just southern Utah. [music] Hundreds of miles north, Mia's older brother, Dustin, abandoned his home and went into hiding [music] with his family, terrified he was Mia's next target. >> He was supposed to have a transition from a male to a female surgery after night. >> Okay. >> So, we think that when my client called the hospital and said, "Hey, he shouldn't have this surgery." He's just been really upset because he was trying to get my parents to pay for it. I'm concerned that he may show up at my house in South Jordan because he knows that we were, you know, kind of trying to delay this and he was mad with me the last time. >> Throughout the night, the hunt for Mia continued, but the darkness and thick brush made the search difficult. Then finally, by chance, officers spotted a suspect matching Mia's description. As they got closer, they confirmed IT WAS MIA. >> MIA, STOP RIGHT THERE. Mia pulled a gun and took off running into THE DESERT. >> MIA, STOP RIGHT THERE. >> Detectives followed behind at a safe distance and began coordinating with other officers to set a perimeter. >> LET'S TALK ABOUT IT. MIA, STOP RIGHT THERE. >> Hunker back behind the bush though. She can come up on your left. I can't see. We need lights. >> He's walking towards a house. What do you think? He goes towards that house. Do you want us to take him out? Police were on the verge of shooting Mia to prevent her from entering a neighborhood and causing more harm. But then suddenly Mia quickly turned and re-entered the unpopulated area. Police lost track of Mia and the search continued [music] into the morning. Then 911 received a call that a suspicious person [music] was seen in an open field. Bingo. Heavily armed officers from multiple [music] departments converged on the abandoned desert lot. >> This is the police department. We have you surrounded. Come out with your hands up. >> Yeah. Police department, come out WITH YOUR HANDS UP. COME out with empty hands. Follow directions and we can take you in safely. Put your hands up and walk out slowly. Mia, police department. Come out with your hands up. >> You're under arrest. Come out with your hands up. [music] After a tense standoff, Mia finally surrendered. >> Come to us. Come to us. Walk to us. >> Walk to us. Keep your heads where I can see them. You go down on your knees. Go down on your knees. Put your hands on the ground in front of you. Slide your body back until you're laying on your face. Take your arms out by your sides. Keep going. Bring your palms up. Do not move. >> Right here. >> I'm [music] back here taking pictures of the gun. You have anything hidden in the bra? >> Those aren't too tight, right? >> Well, okay. >> This is the plastic I was telling you about, Jerry. Okay. Super super good, dude. He's going to give it to you straight. Okay. He's not going to BS you on things. Okay. >> Behind the calm voices and friendly tone is a strategy. The prosecutor is here for one reason. He wants Mia talking. If Mia stays silent, prosecutors will be forced to rely only on physical evidence, witnesses, and circumstantial facts. And even strong cases can sometimes fall apart in court. >> We're here to work with you. Okay. >> So, instead of intimidation, they use kindness, hoping the suspect will lower their guard and confess everything. >> We can work on maybe getting a change of clothes as well, so little more comfortable. Just a little bit left. You're going to get some of your voice back, right? >> While waiting for lead detectives, Mia displays compulsive behavior and obsessively cleans. >> They're wiping these off. >> Do you mind if I stand up to brush it off? [snorts] >> Then Mia offers a glimpse into the deep self-loathing for the body Mia was born with. >> I'm going to reach my pants to tuck. That's okay. What is it you're doing? >> Reaching my hands to tuck cuz I want to see this thing. I hate this thing. >> Investigators brace for a difficult interview, but instead they're met with a calm suspect who is articulate and forthcoming. Mia was shockingly open about what happened and was completely willing to describe the killings in disturbing detail. >> So, this is a body cam. It just runs just it protects you. It protects me and it right. I start this off and we're 100% honest. I'm going to assume that there's not been a lot a lot of honesty in your life. So, I'm hoping that we can change that in this interview. Okay. What's your current legal? Is it MIA? Is that how you spell me here? >> Yeah. >> Like I said, this is where I don't want to include anything. Okay. So, I'm going to read your miranda rights. Okay. >> Okay. And with having those rights in mind, is it are you okay to talk to me? >> Yes. >> Okay. I can't say that I've I've done this a lot. Okay. I'm not so much curious as far as what happened, but I'm kind of curious kind of what led up to it. >> Well, let's see. Uh, a whole bunch of backlash from community. I can't go anywhere. I can't go on blocks without people saying I'm trapped to this voice right now. Uh, trap to heartbreaker to a bunch of nasty other stuff. people jumping in front of carts and just being homeless after [clears throat] my family's abuse several times and uh being 20 grand in debt. >> Is it okay if I write some notes just so that I can clarify if I have any questions or just I want to make sure that I don't I'm really listening to you. Okay, >> no worries. I [clears throat] understand. >> So, you said you were homeless. >> Well, I stayed with my uh cousins for 5 days. I paid him $250 cuz we don't want to get a bump. >> Yeah. >> I just say he kicked me out. >> How long ago were you kicked out? >> Yesterday. >> Oh, yesterday got kicked out. He just thought I was going crazy. So, >> prior to living with the cousin, Mia claims an old landlord made some serious threats. >> He threatened to shoot my ankle, shoot my balls, shoot my back, slow kill me, among other things. So >> I I can't even imagine what that's like. And then you said you were $20,000 in debt. >> Well, I come from our loans cuz my brothers this comes from credit cards. >> It's expensive to be a single woman and transtop. So well, it's like $512 a month just doing uh the trail stuff. So that's like getting laser treatments and medications to um before until I got an auto injector. That was $125 a month. So then all a lot of stuff adds up. >> Oh yeah. What type of medication? >> Uh just HRT. You want to know the specifics? But yeah. >> Now they dive into the heart of the motive. Mia's mom calling the hospital to cancel the gender reassignment surgery. So [clears throat] your mother contacted the hospital. >> Yeah. Let's just say I was very furious and I asked her like I don't want to hear explain, you know, excuses. Want to hear like you know my explanation and I'm sorry and I'll do something about it. She can't say sorry to save her life. Apparently I tried giving her so many chances through my life but um that's besides the point. didn't want to call the hospital and say I was just angry and just did something about it cuz I was the one home even though I was homeless and all this other crap going on in my life but had one thing going on and uh just did a better one for me. So >> I can I can understand the frustration you're talking you're talking a lot of lot of stuff on your plate >> to get backstabbed like that the most backstab ever. [snorts] >> Did they know that that was your ultimate goal? Yeah, I told it was going to several times and I needed it so bad and my mental ability was declining and that's why I needed that surgery. I uh I knew I was going down regardless but I was like well you know enough was enough taking somebody with me. >> So when did you when did you have that decision that enough was enough and that it was going to happen? >> The same day. >> Same day. >> Yeah. when she refused to apologize again. She's just angry other always angry. >> So sick of it. >> Yeah. You can only take so much. >> Yeah. Homelessness or you know being treated like [ __ ] out in public to having a bunch of debt to not getting a surgery only can take so much. >> Yeah. There's eventually a boiling point that I don't think anybody can actually control. And I tried went to pickle ball, went to volleyball, seek out friends. I went to the hospital. It's not like I didn't seek out help even through the cops. >> Yeah. Well, when was the last time you think you searched out help with the cops? >> Not too long ago. It was just that day. >> Like I said, I can't even imagine being in your position and that one thing that you want so bad to be taken away from you. Yeah, that's I'm sorry. >> This is not so much want. I have like 16 reasons. [snorts] It's need. >> Yeah, need. Yeah, you're right. Sorry. That's that's a want is is a bad word. When you're there's a position, like I said, I don't understand it as much. It becomes a need. >> Yeah. >> What about your grandma? >> Uh my grandma's most supportive in my family. >> She's the most supportive. >> Yeah. If you know me too, you wouldn't think so. >> So, did you talk who did you talk to after Jenny? Did you talk to grandma? >> Uh, no. I uh rushed over to my parents to do the deed. >> Okay. When you say do the deed, what what do you mean kill them? >> To kill them. When did you make that decision? >> It was for the moment. I I I still still do it even. I don't regret it. I hate them. >> Okay. >> That was the last I forg. What what did you use to kill your parents then? >> A gun. >> Gun. >> And I knew uh I had to point at you guys, but I heard the conversation. You're not going to go for the kill shot. So >> So that's what kind of had landed you where you surrendered. >> Yeah. You know, I had people pass by, but mind your own business and >> Yeah. >> You know, you're not part of dead people for the day. >> Yeah. >> Or for life, I should say. >> Were you able to tell me what happened at your parents house? got parked there and told myself to >> [clears throat] >> uh throw away that part of me really, you know, that hesitant like always and ran in the door and shot at her person. Dad was [clears throat] in your dad in the same room. >> No, he walked out. What's going on? And I point the gun at him and say then I went downstairs with my brother. I said, "You ruined my life." >> Gotcha. So, do you remember do you remember how many shots you fired at you? >> It's a 12 um clip. So, probably like three rounds left. They all hit her and didn't see it. That's why I shot so many times. >> Just went right through her and [clears throat] so I made sure she was dead. So, I shot at her again. >> Okay. >> Tried to get in at least. >> Okay. And then dad comes around. What's up? What's going on? >> Yep. And I ran his head and it was instant. They just fell backwards. >> So you shot him? >> Yeah. Then I go downstairs. She went around cuz I was going to my brother interfering. And um [clears throat] >> So what was the what was the round for then? >> Message. >> Just a message >> or so. Yeah. >> What what would you what would it be like if you would have hit him? >> Well, it's an [ __ ] >> And then you were saying that after you fired the round through the door, you would back up to make sure it happens. >> Make sure he's dead. >> Okay. So >> it was dad first and then >> and then you heard your mom but she was still >> still kind of light. Yeah, some are still kind of light. So >> and then I shot her again. Kind of understand as far as the gun, where did you get the gun from? >> Pawn shop. >> Detectives went to the pawn shop that sold me at the gun, which Mia says was bought legally, claiming that her brother Cory's protective order had been dismissed by the court. >> She was nice. I mean, something a little cold behind your eyes, but >> yeah, that's the thing. You never know what people are going through. >> Well, I thought I'd be freaked out working here sometimes. You're crazy. >> People are crazy. You never know. [snorts] >> I'm really sorry. >> I I you know, I uh to be honest with you, I wish, you know, one, I wish mental health services were better. I wish the transitioning services were better. I wish that people's opinion it were more accepting of people. >> Absolutely. >> And so I'm sorry that and even in family I'm sorry that it came to this. >> Yeah. >> Um is there anything else that you think that you want me to know? >> I [clears throat] technically broke the productive order by buying the gun. >> Who's the protective order? Who? Who? >> My brother. Like [ __ ] head of her brother. >> The one that you fired at? >> Yeah. How did you end up buying a gun? Did you miss that? I guess >> it was dismissed in court but was a private agreement. Um, do you did you when you went and bought that go, did you think it was going to come to this? >> No, I didn't actually. >> Even if I didn't have a gun, I still would have killed my parents a different way. >> Okay. >> So, >> as far as his remorse, you you're saying that you there's nothing. >> I gave mercy to my brother that day and I didn't point at him. He uh no more mercy. I my mercy and caught me all that [ __ ] and uh so much for family. >> Yeah. >> So So I was trying to spent years trying to fix that broken ass family, but uh eventually just had to get out. >> Okay. >> Is there anything else you want to know? >> Well, I knew that even if I were, I can tell you what I could have done a lot better. And I knew all of it ahead of time. I could have put a silence around it. I could have cleaned the rounds and I could have, you know, like I said, clean the rounds, pick up the rounds of love. >> You guys still would have found out regardless. It didn't matter at that point. >> You're very intelligent to be honest with you. [clears throat] You got you got a lot. You got You're very very intelligent. >> Yeah. >> Do you ever look back right now and wish you would have done anything different? Honestly, there's nothing I could have [clears throat] done different. >> If you if you were to give me one last one last statement from you, what? >> Well, uh my statement would be to uh transgender people and let them start earlier, not like super early. I mean, the sooner the better and it costs so much less and it's so much less stress. But, uh, >> when do you think that's appropriate for the surgery? >> At least 18. Like, >> when you when you're an adult when you can make your own decision. >> Yeah. >> So, being 28 years old now, what at what age did you know that you wanted to transition? >> I mean, since I was born, I kind of hid it for so many years. I played that Alfred Chad role and I hated it. >> No, it wasn't me. It was a disguise. [clears throat] As the interrogation continues, a new detective joins in, digging deeper into Mia's state of mind leading up to the killings. >> There's only just a couple questions that I had if I can if I'm okay to clarify. >> Sure. >> Your dad was your dad was on board about paying some initially. >> Initially. >> So, when you walked into that house, was your mom your only only target? Your dad just got annoyed or were you? >> No, my dad was part of it though to a lesser extent. He didn't have me back when I needed most once again. So, he never kept their promises. I hated that. I didn't want to be that person. Hated lying. >> Yeah. You wouldn't think so. >> Yeah. >> I just I hate it. >> So many lies in my life that I don't want to be part of that. >> I want to just clarify as far as any remorse that you have. Well, I the remorse was I didn't want to become the monster that they uh made me to be. I really wanted to be good. I really did. >> But uh [clears throat] like I said, that was a last resort or last drop. >> I checked every I tried doing every single option before that. Seems like you checked every box that you wanted to before this and this is where >> I checked every box I could possibly link up to get help. >> So if you could go back. >> There's nothing I could have done. Nothing I could have done but different that I could possibly think of. I tried. I literally did but uh it was a no or never situation on the surgery. And uh >> And was it clear to you then that it was the surgery been cancelled because of your mom? Yeah. >> But as far as your transgender assign reassignment surgery, was it going to be I know that there's just breast augmentation or I know there's also um >> I mean that's going to be >> or wasn't going to get anything else maybe like belly but no that was that was the one >> the breast augmentation was the >> no major. Okay. >> So yours was an actual like lower half reassignment surgery to a female. If you could go back to yesterday, would you change the outcome of your mom and dad? >> I don't think there's any way to change their mind. So, no, cuz they're so narcissistic. >> Their answer was on them. They had their chance. >> Well, there was no option for her to be able to say, "Okay, yeah, I'll change my mind." >> No, I knew if I knew if I hesitated and [clears throat] went to sleep, I would have done it. Mhm. >> And then I just regret my life more and more and more, get more angrier, and then it wouldn't it wouldn't be just my mom and dad. >> So that decision was made to not have any conversation when you walked through the door? >> No, that was decision to kill. >> Yeah. >> Yeah. My decision was done. Like this is I'm done with this crap. >> Yeah, that makes sense. So >> did your mom say anything? >> The last word. Were there any last words from your mom? >> I can't quite remember to be honest. Did you remember your dad saying what's going on? >> Yeah, my dad's face that though I remember the image quite clearly the way he that one affected me more. >> Yeah, a lot more. >> Did you think that it would affect you as much as it did? >> Um, it didn't affect me very much to be honest right now. I guess cuz uh I've always struggled with two sides of myself. >> Have you been diagnosed with schizophrenia? No, that's what I just go to the hospital for. >> Anyway, I've tried all those medications and they just screw me up. >> Yeah. >> For what it's worth, I'm one, I'm glad you're okay. >> Okay. >> No, no, you're dared to kill two people. >> I'm I've done this job long enough that that the death of people doesn't affect how I'm talking to you right now. Like, I'm genuinely >> I'm genuinely I'm I'm glad you're still here. Okay. because I wanted to talk to you. I wanted to get my story. >> Yeah, we do have your story and I appreciate that. You're the only one that can give it, like I said. >> But we definitely appreciate you. Honestly, we do appreciate you giving us your story. We do. [music] >> All right. [music] [music] After the interrogation, detectives [music] received an interesting call from a witness who says she ran into Mia the morning of [music] the murders. >> I should call and let you guys know what happened when I talked to that guy, >> okay? >> Which I thought was a girl. I uh my husband and I were at [music] the the old St. George Temple. And so when we were coming out, that girl who I thought was a girl [music] and was starting to exit the temple, this thought came to my mind, show her the love of the Savior. So I said, "Hey young lady, I love those cowgirl boots. I had a ranch for 30 years and I noticed any really cute cowgirl boots always, >> right?" and she turned around and she said why thank you. She raised her leg to show me, you know, and when she did that, I thought in my mind I thought this is guy. >> Oh, >> right. Then I knew with hairy legs and guy's legs. So we started walking. I said, "Well, you have uh enjoy this beautiful day." Cuz it was cooler that day, [music] >> right? >> I said, "Enjoy this beautiful day." It's unfortunate the circumstances, but >> my first thoughts were, what could I have said different to stop [music] this? What could I have said different? And if that was my son who's 28, I wouldn't want him living at home either, >> right? >> You know, that's his choice. I'd still show him the love of Christ, but also tell [music] him that's not, you know, my belief. >> Mhm. While awaiting trial at the Washington County Jail, staff attempted to move Mia to [music] a different cell and Mia violently resisted, punching one officer in the face and kicking another in the knee. The outburst earned Mia two additional [music] felony charges for assault. A lengthy public trial was avoided because in November 2024, Mia accepted a plea deal, pleading guilty and [music] mentally ill to two counts of aggravated murder and one count of aggravated assault. At Mia's December sentencing, [music] surviving family members delivered emotional statements. Brother Corey Bailey told the court, "There could never truly be justice in a case like this. We lost our parents and we lost a [music] sibling, too." Another brother, Dustin Bailey, described their parents as loving and hardworking people who had spent years [music] trying to help Mia through worsening mental illness. Mia's attorney read a statement on Mia's behalf, expressing deep remorse and claiming that if Mia had gotten proper help, the tragedy could [music] have been prevented. The judge handed down two consecutive sentences of 25 years to life for the murders, plus up to 5 years for the attempted murder of Mia's brother, [music] as well as additional time for the jail assault. So, at minimum, Mia will serve [music] 50 years. Barring a successful appeal, Mia will not be eligible for parole [music] until 2075. Following sentencing, Mia was transferred into the Utah State Prison System. And because of a [music] Utah law that took effect in 2024, transgender inmates are initially housed according to the biology of birth unless correction [music] officers later approve an appeal for alternate placement, which would require [music] an in-depth security review. As a result, Mia was originally housed in a men's housing unit while prison officials evaluate long-term placement options. [music] [music]
