Teen Says A “Demon” Made Him Murder His Girlfriend; His Mom Charged With Helping Cover It Up

A horrific story out of Pennsylvania: an 18-year-old college freshman brutally stabbed to death in her own vehicle, by her own boyfriend. 18-year-old Royce Moser told police a demon took over him and told him to stab Karoline Heintz after a late night argument. Moser then called his mom, who reportedly admitted to helping her son cover up the crime, cleaning up blood from the car and her son’s clothing, then throwing away the murder weapon. Both mother and son are now in custody facing multiple charges.

Speaker 1: An eighteen year old stabs his girlfriend, kills her. Why would he do that, Well, he says the demons told him to do it. And with that, welcome to this episode of.

00:00:15
Speaker 2: Amy and TJ. Another one.

00:00:17
Speaker 1: Really, we're dealing with Lindsey Clancy and psychosis and voices his Is this for real?

00:00:24
Speaker 3: Yeah? I mean this is what he claims. We are talking about eighteen year old Royce Moser. And yes, he is charged with his girlfriend's murder, and yes, he claims that a demon instructed him to kill her and then he called his mommy.

00:00:44
Speaker 1: Okay, the did the demon stop instructing after the killing, because this is a dumb ass demon, because the plan they had afterwards is in saying, yes, folks, he called his mommy, and mommy tried to help cover this up. That is the story right now coming to us out of pennsylvani And.

00:01:00
Speaker 4: You know what's remarkable.

00:01:01
Speaker 3: I even saw a quote from the police department saying that they've never seen a crime like this solved so quickly, as in, within a few hours, they knew who the perpetrator was and he was under arrest along with his mother.

00:01:19
Speaker 1: Some of this stuff is mind boggling to think they thought they were going to get away with this in some way, as if this young bright Night was he was eighteen.

00:01:29
Speaker 4: I think she was a freshman in college.

00:01:31
Speaker 1: Freshman in college, about to make her soccer debut in college. All this is coming up and she goes missing and they're not going to show up to the boyfriend first.

00:01:40
Speaker 3: Ultimately, her father had been tracking her every movement with her phone and even had an air tag in her jeep. There was no way anyone was going to get away with doing anything with this young woman to that point.

00:01:53
Speaker 1: As an aside, man, this is a lesson to you. No, it didn't save this young lady, but robes they were able to find exactly where she was, to be able to pick up your phone and track your kid or somebody that might be in danger.

00:02:09
Speaker 2: We should all have these things.

00:02:10
Speaker 4: I know.

00:02:10
Speaker 3: And you know, as soon as you said that it wasn't it wasn't able to save her.

00:02:16
Speaker 4: I got chills from head to toe. But it solved the crime.

00:02:19
Speaker 3: And because her father was so aware of her movements and where she was, or at least where her phone was and where her vehicle was, it led police straight to her boyfriend. And you know what's also just so eerie to think that eleven weeks ago, this cute, adorable teenaged couple had just attended high school prom together. The picture is everywhere. They look sweet, they look young, they have bright futures. They looked in love under the caption of this high school prom photo best two nights of my life ever, I mean, how do things go from that to where we are now?

00:03:01
Speaker 2: Pictures perfect? It's like Central Casting, It's like the it's all American photo.

00:03:06
Speaker 3: Yes, Jack and Diane, teenage couple that everyone's rooting for.

00:03:12
Speaker 4: And it went from that.

00:03:14
Speaker 3: To just this atrocious, awful murder that he can't explain other than to point to demonic possession.

00:03:24
Speaker 4: I don't understand.

00:03:27
Speaker 1: This is an incredible story, rogues because some of the details of what happened are confusing. That he had time to take a pause and go in and get a weapon and then come back. Even it's hard to piece together what anger or what had overcome because it didn't seem like a rushed situation necessarily No.

00:03:49
Speaker 4: And that's the thing.

00:03:50
Speaker 3: So here is what he reportedly told police. So he's reportedly confessed to this. Mom has confessed to her role in this. According to authorities, but Royce told investigators that his girlfriend came over to his house right around ten pm.

00:04:06
Speaker 4: He said.

00:04:07
Speaker 3: Different accounts are that basically they were talking about their future. Parked in the driveway of his father's home. He became angry at some point, and he says he doesn't remember why. He doesn't remember what made him mad. But he told her to wait, that he had something for her. And that's when he said a demon told him to stab her name, by the way, we haven't even said her name, yeah, eighteen year old Carolyn Heinz. And he claims a demon told him to stab.

00:04:41
Speaker 4: And kill his girlfriend.

00:04:43
Speaker 3: So he walks into his father's home and grabs a kitchen knife. Meantime, by the way, think about Carolyn sitting in the vehicle. She's not alarmed, she's not afraid, she's not scared. I'm thinking if something was so heated, or something was so menacing, or things got so bad, as I have something for you. If she felt in any way threatened or scared, she had an operating vehicle, keys to her car, she could have taken off the fact that she didn't suggest that she didn't feel like she was in danger. That's what's really bizarre. So he then comes back to the car and stabs her fatally in the chest.

00:05:23
Speaker 1: Rose that part or something bizarre about that. I mean, look, we were believers in a lot of stuff. Maybe we watched a many horror movies, the demons in the head type.

00:05:35
Speaker 2: That the idea of it. But it's just the fact.

00:05:37
Speaker 1: That she waited doesn't necessarily lend itself to an urgent or really heated situation. I guess they could.

00:05:45
Speaker 2: What would he have gone in to go get.

00:05:48
Speaker 3: Maybe she thought he was going to give her a gift and apologize, But obviously his demeanor or what he was saying to her, or the fight they had had wasn't so severe where she felt like she needed to get away from him. That's what's so chilling, because she sat there and waited for him to come back, and he came back with a kitchen knife, and after he stabbed her, he then loaded her body into her trunk into the vehicle of her into the trunk of her jeep, calls his mom and drives her in the trunk of her own vehicle dead to his mom's house. What does mom do the unthinkable? She tries to help him get away with it, what was mom?

00:06:35
Speaker 1: Mom wasn't thinking she was just trying to save a baby, wasn't she She knew baby was going to jail the rest of his life.

00:06:42
Speaker 2: I don't know.

00:06:44
Speaker 3: Well now she is too, probably because yes, according to police, and again they are saying that mom has confessed to all of this that went back to her house.

00:06:54
Speaker 4: Mom says, I know just what to do. Follow me.

00:06:59
Speaker 3: He draws his girlfriend's car again with her dead body in the trunk. She's right there with him to a university parking lot, and just leaves the vehicle there with her inside, drives back to mama's house where she's washing her son's clothes, cleaning the car, telling him to shower, throwing away the murder weapon.

00:07:22
Speaker 1: I mean, they didn't really think they were gonna get it. I mean, this is not even trying that hard. I mean, what was the plan here?

00:07:28
Speaker 4: It's bizarre.

00:07:29
Speaker 3: And meantime, this entire time, Carolyn's dad is tracking her because she said she was going to go to Target and then go back to her dorm room. He checks her location and sees she stopped at her boyfriend's house.

00:07:42
Speaker 4: He knows where he lives.

00:07:43
Speaker 2: It's nothing to be alarmed about.

00:07:45
Speaker 3: There, and thirty minutes later he sees her phone moving again, and then he's confused because of where the.

00:07:53
Speaker 4: Phone and the vehicle end up.

00:07:54
Speaker 3: He tracks the air tag in her vehicle and thinks, why is she in the library parking lot to go back to her dorm room. He tries to call her, tries to call her, she doesn't answer, and eventually he calls police, and because he can track her phone and her vehicle, police know exactly where to go find the jeep. Man.

00:08:12
Speaker 2: These things are so valuable. Oh my goodness, we should all have these for everybody. I don't know.

00:08:18
Speaker 1: Some people call them invasions of privacy and don't like the idea of being tracks. But my god, we have seen cases of these things save in people's lives.

00:08:24
Speaker 4: Absolutely, my goodness. Absolutely.

00:08:26
Speaker 3: Unfortunately, there was no saving Carolyn because according to her boyfriend, he I guess he stabbed her in the heart or at least in an area where.

00:08:35
Speaker 4: It was fatal, and she didn't have a shot.

00:08:37
Speaker 3: But when police found the jeep, the first thing they saw blood splatter inside the vehicle and outside the vehicle, which is kind of interesting because according to the mom and the son, they tried to clean the car up and in fact, there's surveillance footage.

00:08:53
Speaker 4: Get this.

00:08:54
Speaker 3: They can see the teenage kid, Moser, wearing blue latex glove driving his girlfriend's jeep to the library, and then sees another car with a female driver, also wearing blue gloves behind him.

00:09:10
Speaker 1: I don't know what they were thinking, Broes, is there's a dead girl here. But that is comical, criminal work, horrific, that is what are they thinking. They weren't thinking. I don't know, Robes, this was Oh God, what bad decision after bad decision?

00:09:27
Speaker 2: I think Mom that night, Mom, no she be now, yeah, I know she regrets that.

00:09:34
Speaker 1: But like you said, man, no, no regard for that young lady.

00:09:38
Speaker 4: That's what I'm thinking.

00:09:39
Speaker 3: This is a woman who I'm sure she has allowed into her home plenty of times, took some of those prom photos herself, probably standing probably next to his girlfriend's parents. I would assume that they all know each other. How do you not have any regard for her wellbeing, for her family regardless. I get your instinct as a parent to protect your child, but at the expense of someone else's that's where I draw the line.

00:10:03
Speaker 4: I don't know.

00:10:04
Speaker 3: I just think that's really hard to get my head around, and it wasn't. I mean police found her just after midnight. I mean it was just a matter of two hours basically before they found her body. And then they go when they find the chef's knife inside a garbage bag that matches the exact description, and so they find the murder weapon almost immediately. Like this was the quickest investigation that led to charges that a lot of police departments have ever seen.

00:10:33
Speaker 4: At least it was depicted that way.

00:10:35
Speaker 1: They sure do make it easy when they take photos and latex gloves. Well again, they're just not thinking and the mom I'm sure just just panic. Oh my god, we just watched this scenario play out in a movie. What was that movie, Hollow Road?

00:10:48
Speaker 4: Oh yeah, it really truly did.

00:10:51
Speaker 2: This really was and you know what it was capted.

00:10:53
Speaker 1: It seems weird to I guess suggest but if you watch this movie as a parent, you see this desperation that kicks in with these two people who are trying to save their child from possible criminal charges, and they start making bad decisions and it's so well acted and it really does.

00:11:08
Speaker 2: It's Wow, it's this scenario.

00:11:10
Speaker 3: Wow, it's Matthew Rise and roosevend Pike and so well acted. Most of the entire movie is set in a vehicle as they're trying to get to their daughter, who she claims accidentally hit and killed another teenage girl. But it turns out she was high and they knew she was going to face charges, and so they were trying to cover it up for her.

00:11:30
Speaker 1: Yeah, and even you see the parents kind of disagree on the strategy and the way forward.

00:11:35
Speaker 2: So anyway, think I haven't thought about.

00:11:38
Speaker 4: That, babe.

00:11:38
Speaker 3: This is actually life imitating art in a lot of ways. And look these official charges now, So the eighteen year old Royce Moser is facing homicide, tampering with evidence, abusive a corpse, conspiracy to commit tampering with evidence, conspiracy to commit abusive a corpse, and obstruction of justice. Mama isn't facing murder charges, but she has hindering the app aprehension of a fugitive, tampering with evidence, abusive a corpse, conspiracy to commit tampering with evidence, conspiracy to commit abusive a corpse, and obstruction of justice. I mean, she is going away for a long long time. And by the way, both of them are behind bars right now. And this is just a tragedy that just turned into an even greater one because of decisions before, during, and after.

00:12:27
Speaker 4: And look this talk of a demon.

00:12:29
Speaker 3: Haven't heard anything specific, anything more than that, but certainly that's headline grabbing, but head scratching as well. Don't know if this kid had any history of mental illness, but there is no suggestion that he did. He wasn't currently enrolled in college, but he had just graduated from high school. This is just awful, but.

00:12:48
Speaker 1: It seems like a weird thing to him for him to immediately pull out out of nowhere. I heard demons. I mean, is this something he discussed with his mom as a part of their really.

00:13:00
Speaker 3: Yeah, guilty, like not guilty by reason of insanity. They're already maybe were thinking about what his defense could.

00:13:07
Speaker 2: It kind of reads with how they have handled this whole situation. It kind of does.

00:13:11
Speaker 1: It sounds stupid if you're going to do this, But again, we don't know his history. Maybe he has some mental health something that we don't know about that needs to be considered.

00:13:20
Speaker 3: My goodness, Well, when we come back, we want to talk about who Carolyn Heinz was, TJ said at the beginning of this episode, Yes, she was about to make her soccer debut at her brand new college.

00:13:32
Speaker 4: She was just about to start her and launch her.

00:13:36
Speaker 3: Collegiate career, her soccer career.

00:13:39
Speaker 4: This is beyond sad.

00:13:40
Speaker 3: We're going to talk about Carolyn Heinz when we come back and welcome back everyone to Amy and TJ. We went over this atrocious crime and this notion that somehow this teenager who just graduated from high school somehow claims he was overcome by a demon, that a demon told him he had to stab his eighteen year old girlfriend, Carolyn Hinz. Yeah, she was just starting college. Just I mean, we just sent Annalise back to college.

00:14:21
Speaker 4: This is that time of year and she's a freshman. She was probably so excited.

00:14:25
Speaker 3: She was heading back to her dorm room. She was just hanging out with her dad. A freshman at Pennwest California. It's about a half hour from Pittsburgh. To give you an idea of where it is in the country, folks, I.

00:14:37
Speaker 2: Did not know there was a California Pennsylvania.

00:14:39
Speaker 4: I did not know that. Yes, it was a little confusing.

00:14:43
Speaker 3: I'm like California campus in Pennsylvania, but Pennwst California and she was a defender, and she was I mean, how exciting is that you're a freshman Division two soccer a defender. She was set to make her collegiate debut for the Vulcans, and it was the game was scheduled for this week. She was days away from just really starting out on her future beyond sad.

00:15:05
Speaker 1: I look forward to seeing how they hate they have to do it, but I hope they honor her in some probably some really cool way this week for the game.

00:15:13
Speaker 3: They've got to And look, they've already released a statement they said, California Athletics is devastated by the tragic loss of our student athlete, Carolyn Hinz. Carolyn was a bright and kind young woman with so much ahead of her. She will always remain in our hearts. Our deepest condolences are with her family, friends, teammates, coaches, and all who knew and loved her. We've seen this, unfortunately, when you have a student athlete who somehow, for whatever reason, dies young, they do. Usually it's usually beautiful, the tributes that these student athletes receive at games, and she it's just so sad to think about such a beautiful life cut short.

00:15:53
Speaker 4: For what reason. We don't even know.

00:15:55
Speaker 3: He can't even It's weird that he can tell us or tell police that he heard it demon, but he can't remember what they were arguing about. He can't remember why he got mad, He can't remember what set him off.

00:16:07
Speaker 1: Well, that's pretty lame excuse to just pull out of your butt out of nowhere. I heard demons. You really think somebody's going to buy that?

00:16:14
Speaker 2: So did he? Could this be legit? I mean, I don't, I don't know. It's unlikely we should say that.

00:16:22
Speaker 3: I mean, first of all, insanity defenses are almost impossible. They're very rarely effective. They very rarely end in a not guilty verdict. Now, it is interesting you mentioned Lindsay Clancy. We have it on in the background. Obviously we've been following that story, and she too has a not guilty buy insanity defense, and she too admits to killing her three children. But this was a woman who had a diagon like she has a long history of seeking help for a mental illness, for postpartum depression and ultimately postpartum psychosis.

00:16:56
Speaker 4: There is no word and no record.

00:16:58
Speaker 3: I've looked at as many any articles as I possibly could find to see if anyone mentioned a history of mental illness, maybe it's because he's eighteen, and maybe because all of that would be when he was a minor, we might not be privy to that. But in nowhere or in no article did I see any reference to him having any difficulty, any issues. And look, all we've heard from her father is that he tracked her down and he found her killer, but not in time to save her life. Incredibly, incredibly said, we'll continue to follow this story. There are obviously a lot more There is a lot more information that needs to come out in this case for a lot of people to make sense of this. But that community is mourning, that campus is morning, and certainly our hearts go out to her, her family.

00:17:44
Speaker 4: That's just it's so sad you send your kid off to college. This is not what you expect.

00:17:49
Speaker 3: We wanted to let y'all know about what was going on there, and we always appreciate you listening to us.

00:17:54
Speaker 4: I'm made robot alongside TJ. Holmes. We'll talk to him.

00:18:00
Speaker 2: The two things
