Netflix's The Crash has reignited one of America's most divisive true crime cases, sending viewers down a rabbit hole of evidence, testimony and unanswered questions surrounding convicted killer Mackenzie Shirilla. But while the documentary presents a tearful, remorseful young woman insisting she is innocent, a former inmate who served time alongside her is telling a very different story.
Shirilla was 17 years old when she drove a car at 100 miles per hour directly into a brick wall in Strongsville, Ohio, in the early hours of July 31, 2022, killing her boyfriend Dominic Russo, 20, and his friend Davion Flanagan, 19. Black box data showed she never lifted her foot off the accelerator. She was the only survivor.
At her trial in 2023, Shirilla's defence team argued she may have suffered a medical episode linked to postural orthostatic tachycardia syndrome, known as POTS. No medical records or expert testimony confirmed the diagnosis, and the judge was having none of it. Judge Nancy Margaret Russo described Shirilla as "literal hell on wheels," concluding that the crash was "controlled, methodical, deliberate, intentional and purposeful." She was convicted on all 12 felony counts, including four counts of murder.
Under Ohio law, murder carries a life sentence, meaning there is no fixed end date to Shirilla's imprisonment. She was handed two concurrent 15-year sentences, meaning they are served simultaneously rather than one after the other, and will not be eligible for parole until October 2037. She is currently serving her time at the Ohio Reformatory for Women. A previous appeal was rejected after her legal team missed a filing deadline by a single day, and her lawyers are now pursuing a further appeal to the Ohio Supreme Court.
In the Netflix documentary, which has shot to number one on the platform since premiering on May 15, Shirilla gave her first ever prison interview. She denied any intent, said she has no memory of the crash, and expressed remorse for the families of Russo and Flanagan. Her parents also appeared, defending her and insisting on her innocence, though many viewers felt their attitude was more damaging than helpful.
But it is the account of former inmate Kat Crowder, now living in Nashville with her daughter, that has generated the most conversation online. Crowder, who served time at the same facility as Shirilla in the early part of her sentence, took to TikTok to share what she says she witnessed, and it bears little resemblance to the documentary version of events.
According to Crowder, Shirilla walked around the prison yard with no remorse whatsoever, was fixated on social status, and treated the whole experience like a high school popularity contest. She was surrounded by a small group of young, social-media-obsessed friends and was beginning to gravitate toward the more institutionalised long-term inmates.
As Crowder put it: "Mackenzie did not walk around that prison yard thinking about those lost loved ones that she claimed to think about every single day. She walked around the prison thinking how is she going to get in with the cool kids. All she cared about was doing her makeup, walking around the yard with her one or two friends, young girls, social media influencer wannabes, thinking that it was a high school popularity contest."
Whether the Mackenzie Shirilla the world sees in The Crash is the real one, or simply a carefully constructed performance, may never be fully known. What is certain is that she will not have the chance to make that case to a parole board until 2037.
