Mackenzie Shirilla: Hell on Wheels | The 100 MPH Crash That Killed Two

On July 31, 2022, 17-year-old Mackenzie Shirilla drove a Toyota Camry into a brick wall in Strongsville, Ohio at 100 miles per hour.

Inside the car were her boyfriend, Dominic Russo, and their friend, Davion Flanagan. Both were killed. Mackenzie survived.

At first, it looked like a tragic accident. But the car’s event data told a different story: full acceleration, no brakes, and a deliberate steering movement toward the wall. Investigators would later uncover a disturbing pattern behind the crash, including a prior threat to wreck the car with Dominic inside, a volatile relationship, and 93,000 text messages.

In this episode of GBRLIFE of Crimes, we look at the Mackenzie Shirilla case, not just what happened, but why it happened. We talk about the psychology behind narcissistic injury, coercive control, obsession, control, teenage relationships, and what happens when someone cannot tolerate being left.

We also discuss the victims, Dominic Russo and Davion Flanagan, whose lives should never be reduced to the person who took them.

Dominic Russo was 20 years old.
 Davion Flanagan was 19 years old.
 Never forget to say their names.

In this episode, we break down the case, the evidence, the trial, the Netflix documentary debate, and the chilling words Judge Nancy Margaret Russo used when she called Mackenzie Shirilla “literal hell on wheels

It's 5.30 in the morning on July 31st, 2022. Strongsville, Ohio is asleep. It's the kind of Cleveland suburb where the sidewalks. Roll up early and the biggest noise on Sunday morning is a sprinkler, cutting on too late. Nothing ever really happens here. There are three people inside a 2018 Toyota Camry. Moving through that quiet, the driver is 17 years old. Her boyfriend is 20. Riding passenger half asleep, their friend, is 19. in the back seat, probably thinking about, well, not much at all. Maybe thinking about going home, although he's dreaming. So he could be thinking about tomorrow. Either way, no one in that car is really thinking about dying. But the car hits a brick wall at 100 miles per hour, not trying to hit the brakes and swerving and hesitation. No, just speed, then concrete, and then nothing. And when first responders cut through the wreckage, two of those three passengers are already gone. But the third is the one who's driving. And she would later say that she remembers nothing. Well, the car remembered everything. Welcome to GBRLIFE Transmissions. I'm your host, Kaitlyn, and you're listening to GBRLIFE of Crimes, where we explore not just what happened in crimes committed by women, but why they happened and the psychology behind them. Today, we're going to Strongsville, Ohio, a tight-knit middle-class suburb southeast of Cleveland, the kind of place where high school football matters and everybody already knows everybody. And we're going to talk about a 17-year-old girl who drove two people she claimed to love into a brick wall at 100 miles per hour on a Sunday morning before the sun came up. About what the car data said, about what 93,000 text messages said, and about what the judge said when she looked Mackenzie Shrilla in the eyes and called her literal hell on wheels. Let's go back to the beginning. Mackenzie Shirela was born on August 2nd, 2004, in Strongsville, Ohio. She grew up with her parents, Natalie and Steven, and her older sister, Danielle. Her father, a graphic designer, and art teacher. So this is a stable household in a comfortable suburb. Nothing in her early years that stands out as a red flag, and there's no documented trauma. There's no chaotic home life. No crisis that surfaces in any public record. She was just a kid growing up in a quiet place until she wasn't. By high school, Mackenzie had built something. She was magnetic, extroverted, the kind of person who fills a room without trying. Classmates described her as popular in ways that had its own gravity. The girl that other girls followed around without quite knowing why. And there were reportedly over a hundred students at Strongville High School who orbited her. People who tracked what she wore, who she talked to, who she was with. She had also discovered TikTok and she was good at it. Lifestyle content, fashion reviews, and natural ease in front of the camera. She was building a following, building a brand. She knew how to be watched. She liked it. And that's important. Not because being popular or wanting a following is a warning sign on its own. It's important because it tells you what Mackenzie's sense of self was all built on. Being chosen. Being seen. Being the center. That was the foundation. And foundations matter when things start to crack. She did graduate from high school in the spring of 2022. And a few months later is when she drove that car into a wall. But to understand how she got there, you have to understand. her relationship. Because the relationship is everything in this case. Her relationship with Dominic, that is. She met Dominic, Dominic Russo, around 2018. She was about 14 at the time, and he was 16. They were in the same high school, same circles, and they had the kind of immediate connection that teenage relationships are built on. Super intense, all-consuming, and clearly without a lot of guardrails. And Doc was, by every account from people who loved him, a good person. His father, also Dominic Russo, Sr., described him as someone with a big heart, who struggled to walk away from things even when walking away was the right thing to do. His mother, Christine, has spoken publicly about what the relationship looked like from the outside, turbulent, but from the beginning, very on again, off again, in the way that never really means over, just paused. Where breaking up is followed by getting back together and the cycle just repeats and the problems that caused the whole breakup never actually get resolved. They just get buried underneath the relief of getting back together. And by 2021, McKenzie and Dominic start to live together. Two teenagers, essentially cohabitating, in a relationship that was already showing serious signs of strain. And when you layer that kind of proximity and dependency on top of something already volatile, you compress it. The highs get higher and the lows get more dangerous. and the exits now are very hard to find. And by June of 2022, Dominic had been trying to end things. His family has testified that he was pulling away, that the fights had escalated, that he had made recordings of some of their encounters because he was afraid. He had called his mother during arguments so that he could get picked up. A friend once drove out to get him after Mackenzie threatened during a fight while they were driving to crash the car with him in it. So this was nothing new for her, and he told people what happened that very night, at least the first time that she had said that. Nobody knew it was practice at the time. And then there's Davian Flanagan. That third passenger in the car. Davian was 19 years old. He had been adopted with his two younger sisters when he was eight. He was a very gifted athlete, a starting running back with real aspirations. But he had torn his ACL and UCL. So he was in a state of rebuilding, and he fell into Mackenzie and Dominic's friend group during that stretch. But he was also a warm, loyal, and kind human. And his parents described him as someone with an infectious smile and a fierce commitment to the people around him. He was in the backseat of that Camry because he was someone's friend. That's the only reason. He had no part in the dynamic between Mackenzie and Dominic. He made no choices that night that should have cost him anything. And before we get to what happened on that road, I want to talk about Mackenzie psychologically. Because the crash did not come out of nowhere. It came out of a pattern, and that pattern had been visible for years. We don't have a diagnosis. Nobody has handed McKenzie a clinical label before or after this crash. But when you look at the full behavioral record, what it points to is something clinicians would recognize as narcissistic injury, combined with coercive control dynamics. Let me explain what that actually means, because those are not just labels. Narcissistic injury is what happens when someone whose entire sense of self depends on a specific image of themselves. In this case, the girl who is always chosen, always wanted, always central, and is confronted with something that shatters that image. It's not just hurt feelings. It's closer to an identity emergency. The self that was built on being chosen cannot survive being left. And rather than that feeling, the response is to externalize it, to make the threat the problem. And what do you do with the threat? You eliminate it. And that is what behavioral record is showing over and over again. Mackenzie did not respond to Dominic pulling away with grief. She responded with escalation. She showed up. She threatened. She made it impossible for him to leave without consequence. She tried to break into his house. She made recordings his mother described as alarming. And two weeks before the crash, she told him directly that she would wreck the car with him in it. Again, it wasn't the first time. Nobody knew it was practice. How would you know that was something serious? They knew that she was seriously having some issues, but not that she would actually take action in those specific things she threatened. So when he called for a ride and got out of that car, she took it as a step back to overcome. But that is coercive control, using fear and escalating threats to maintain power over another person in a relationship, making the cost of leaving so high that leaving feels impossible. It's a pattern more commonly discussed when the perpetrator is male. That doesn't mean that belongs to any gender. It's just that it's more commonly seen in male perpetrators. But the witnesses had described it, and the prior threat proves it. 93,000 text messages is the other part of this. Think about that number. That's not a relationship. That's surveillance. That is someone who cannot tolerate the silence between messages because silence feels like distance, and distance feels like abandonment, and abandonment feels like the whole structure's collapsing. So the texts swing between rage and desperation, threats and declarations of love. That's not a volatile teenager, that's documented behavioral profile. And here's the part that I think is more important in this situation. Mackenzie couldn't see Dominic as a person who had a right to leave. She treated his attempts to create distance not as a decision that she had to respect, but a problem to solve because he wasn't separate from her in her internal world. He was part of her identity. And when he tried to take himself back, that's when she experienced it as being taken apart. And that's what July 31st was. The end of every other option that she knew how to use. He was leaving for real this time, and she had nothing underneath all of that external validation. The following, the status, the relationship to fall back on when it was gone. So she made it so neither of them had to find out what came next. And on July 30th, 2022, the group attended a high school graduation party. Around 5.30 in the morning, they left. Mackenzie was driving. Dominic, passenger seat, Davian in the back. Investigators would later say that McKenzie had driven that stretch in the days before the crash. So that location was not random. McKenzie had noted that building and decided to come back. And on a day to drive, the car accelerated. And the event data recorder captured everything. The accelerator pressed to 100% capacity. The speed climbing to 100 miles per hour with only five seconds before impact, a hard searing input to the right. Not a correction, not a reflex. A deliberate maneuver towards the wall, and the brakes were never touched. Not once. The car hit the brick wall, head on. When officers arrived, all three occupants were unconscious and not breathing. Dominic and Davian were dead at the scene, but Mackenzie was pulled from the wreckage and airlifted to the hospital, where she underwent multiple surgeries. She survived. One of the first things that she said while she was in the wreckage, According to the officers on scene, how was Davian? A question that's either a pure reflex of someone who had no idea what she had done, or something more complicated than that. And the trial would spend four days trying to figure out which. Police initially treated the crash as a tragic accident. The car data changed all of those ideas very quickly. Because the sustained acceleration to 100 miles per hour, with no brake engagement at any point, A deliberate steering maneuver five seconds before impact, none of that is consistent with a medical emergency or a mechanical failure or a lapse in attention. That is consistent with intent. Investigators also found evidence that McKenzie had driven that route before the crash, so clearly the location was chosen. And on November 4th, 2022, three months after the crash, McKenzie was arrested and charged with murder. She was 17 at the time of the crash and 18 when charged, so she would be tried as an adult. And in the months between, she returned to social media, attended parties. There are photographs, former inmates who would later describe this period as inconsistent with who they say she is and someone who moves through consequence. The way water moves through a stone. So when the trial began in August 2023. McKenzie waived her right to a jury and chose a bench trial. One judge would decide her fate. And that judge was Judge Nancy Margaret Russo. Same last name as her boyfriend. An irony that no one missed. The prosecution built its case on four things. The car data, 100% accelerator, no brakes, deliberate steering input five seconds before impact, and the prior threat. Remember, two weeks before the crash, McKenzie had told Dominic that she would crash the car with him in it. And a witness heard. And he called his mother to be picked up. That was not a figure of speech. That was a preview. That was scouting. Investigators argued that she had driven that route before and that the location was not stumbled upon. Because of the text messages, 93,000 of them were also reviewed. Years of escalating threats, possessive behavior, violence in the language, and documented pattern of refusing to let him go. The defense argued that she suffered from POTS, a real condition that can affect the heart and cause dizziness and fainting. They said that she experienced a medical episode behind the wheel and that she blacked out and that none of it was intentional. And the car data dismantled that. A person who lost consciousness does not press the accelerator at 100% for several sustained seconds and does not execute a deliberate steering maneuver through a wall. And there's no verified medical documentation of a POTS diagnosis. Or an episode, and no expert testified to confirm this episode ever occurring that morning. The body doing those things is not a body that's unconscious. And on August 14th, 2023, the judge delivered her verdict. Guilty on all accounts. Four counts of murder, four counts of felonous assault, and two counts of aggravated vehicular homicide, but also one count of drug possession and one count of possessing criminal tools. This was not reckless driving. This was murder. And she called McKenzie's actions controlled, methodical, deliberate, intentional, and purposeful. She called her, on the record, in open court, literal hell on wheels. And McKenzie was sentenced to two concurrent terms of 15 years to life. Earliest parole eligibility is 2037. She's currently incarcerated at the Ohio Reformatory for Women in Marysville, Ohio, currently 21 years old. And in May of 2026, Netflix released a documentary called The Crash. Mackenzie appears on camera for the first time since her conviction. Measured, remorseful, someone sitting with the weight of what happened, and the documentary generated enormous debate and put her name back on top of the news cycle. Then former inmates started talking. Mary Catherine Crowder spent over six months incarcerated with Mackenzie. She told reporters the person she watched behind bars looked nothing like the person in that documentary. And that Mackenzie walked around the facility like she was famous, always put together, always performing, Running the social hierarchy among younger inmates... Building her clique, not someone haunted by what she had done, someone who had found a new room to be the center of. Around the same time, reports emerged that Mackenzie had developed an invented language to use during monitored jail calls with her mother. A private code that the listeners could not decode. Think about what that actually requires. Sustained creativity. Teaching your mother to use it. Maintaining it consistently enough over time that it works. That is not someone in crisis reaching for connection. That's someone who, when placed inside a system designed to limit her control, immediately began engineering a way around it. It's the same mechanism as the 93,000 texts. The same mechanism as the prior threat. The same mechanism as everything that came before. The setting is a prison yard. But the pattern is identical. And the girl who had to be the center of every room, She just has fewer rooms to choose from now. So what do we do with all of that? Mackenzie was 17 years old when she drove that car into that wall. That's not a defense. The judge made that clear. The car data made that clear. The prior threat made that clear. And 17-year-olds are fully capable of knowing that driving at 100 miles per hour into a brick wall kills everybody inside. Well, at least the car. And she knew. The judge concluded she not only knew, but chose it deliberately. But I also think that there was clearly something never built inside of her. The whole external structure of her life, the following, status, relationship. She had clearly been in for a very long time, or at least for the short amount of time that she's been on Earth so far. All of it is telling her that she couldn't really tolerate loss because she could always pull him back and she could always recenter her story. Every signal in her environment confirmed that. And nobody around her, not a parent, not a school counselor, not a friend, was... Looked at it like there were all these text messages and they said, hey, that's not OK. We're going to address it before someone gets hurt. And that's not me shifting blame. Two people are dead because of what she chose to do. But prevention requires catching something before it becomes a crime scene, which means paying attention before there is anything else to point to. And nobody paid that kind of attention here. Dominic was 20 years old and he had spent weeks trying to leave a relationship that he was clearly afraid of. He made recordings because he was scared. He called his mother for rides. He told people he was trying to get out, but he ran out of time. And Davian, he was not tangled up in any of this. He just got in a car because that's what you do when your friends are heading out. And Mackenzie didn't even tell him not to go, even though this was her plan. He had a scholarship waiting to be built in his name. An infectious smile. A whole life that was just starting to come back together after his injury. And then he sat down in the backseat of the wrong car in the wrong moment. And that's all it took. His family named a scholarship for him. His parents, Jamie and Scott, built something in the ground where his future should have been. And that's the only kind of monument available to people who lose someone like this. And that's not enough. It's never enough. Dominic's sister, Christine, after the Netflix documentary reignited the whole debate and people started arguing about Mackenzie's guilt again, said something very simple. She's rotten to the core, not measured, not careful. The statement of someone who has been through something that does not leave room for nuance anymore. And Mackenzie's parents have never stopped fighting for her. But that's what parents do. And there have been appeals, but they've all failed. Because the evidence is the evidence. But love does not require evidence to make sense. Two families in Strongville, Ohio are waking up every single day in the world that she made for them. A world without Dominic, and a world without Davian, and a world where a Sunday morning in the summer ended everything. And that's what I want to leave you with. Not a documentary, not a debate, not the coded language or a prison click or the TikTok discourse, just them. Dominic Russo, 20 years old. Davian Flanagan, 19. Never forget to say their names.
