The Ohio Supreme Court has decisively closed the book on Mackenzie Shirilla’s appeals for freedom, dealing a final blow to the convicted killer’s efforts to overturn her sentence. Her most recent appeal was summarily dismissed, following a previous failed attempt that faltered due to a missed filing deadline by a single day.
Currently 21 years old, Shirilla is incarcerated at the Ohio Reformatory for Women, where she is serving a life sentence. Her imprisonment stems from a tragic 2022 car crash that resulted in the deaths of her boyfriend, Dominic Russo, aged 20, and their mutual friend, Davion Flanagan, who was 19.
Tuesday’s decision by Ohio’s highest court effectively seals Shirilla’s fate, ensuring she remains behind bars until at least October 2037. This marks the earliest point at which she will be eligible for parole, earning her the label ‘hell on wheels’ from those following the case closely.
Chief Justice Sharon Kennedy affirmed the court’s stance, signing an order that the court ‘declines to accept jurisdiction of the appeal,’ as reported by People. This decision essentially terminates any legal avenues Shirilla might pursue in seeking relief from her sentence.
Now that her appeals have been fully exhausted, Shirilla’s path to freedom remains blocked until she is eligible for parole at the age of 33, a sobering timeline reflecting the gravity of her actions and the court’s unwavering position.
The decision dealt a crushing blow to her legal team, which has aggressively fought to overturn the verdict through three separate appeals – two in Cuyahoga County Common Pleas Court and another in the Eighth District Court of Appeals.
Her attorneys have repeatedly argued that medical evidence suggests Shirilla suffered from a pre-existing condition that may have caused her to lose consciousness before slamming her sedan into a brick building at nearly 100mph.
They claimed that her trial lawyers failed to adequately investigate evidence that she suffers from Postural Orthostatic Tachycardia Syndrome, or POTS.

But every attempt she has made has been rejected by the courts.
Shirilla brought her case before Ohio’s highest court after using all available options in the lower courts, but it was denied in May 2025.
She filed a motion for postconviction relief after her initial attempts to secure release were denied, a separate legal process used to challenge a conviction or sentence outside of a direct appeal.
Last month, however, the motion was tossed by the appellate court after her legal team failed to meet the strict deadline, filing it 366 days after the trial transcript was submitted – just one day past the cutoff.
She then petitioned the Supreme Court to consider her motion, arguing that because juvenile court transcripts were not filed until months after the trial transcripts, she should have been allowed more time to submit it.
Her attorneys also argued that the delay was the result of a miscalculation tied to a leap year.
Tuesday’s decision comes years after prosecutors said Shirilla, then 17, deliberately drove her Toyota Camry into the side of the PLIDCO building in Strongsville, Ohio, on July 31, 2022, as her relationship with Russo deteriorated.
While Russo and Flanagan died almost instantly, Shirilla survived the crash and was hospitalized with multiple severe injuries.

Evidence presented at trial showed that the vehicle was traveling approximately 100mph in a 35mph zone moments before impact, with data indicating the accelerator was fully engaged and no brakes were applied.
Surveillance video showed the car speeding down a quiet road before smashing through a business sign and slamming into the building, with first responders finding the vehicle split in half in what one officer called ‘the worst crash I’ve ever seen.’
Shirilla has maintained that the crash was not intentional, calling herself a ‘third victim’ who does not need to be ‘rehabilitated’ in shocking phone calls with her mother.
Judge Nancy Margaret Russo ultimately found her guilty in 2023, famously declaring: ‘This was not reckless driving – this was murder.’
‘She had a mission, and she executed it with precision,’ the judge said.
The case has remained in the headlines in recent weeks following the release of The Crash, which revisited the fatal collision and featured interviews with Shirilla from prison.
The Daily Mail had previously reported allegations from former inmates that she cultivated a ‘Mean Girl’ reputation behind bars, embraced the notoriety surrounding her case and showed little remorse for the crash.
A former inmate, who gave her name as Kat, said: ‘She showed absolutely no remorse. Mackenzie acted like it was glorified high school, she walked around like she was famous.’

Kat also revealed that Shirilla was enjoying such torrid romances with other women that she would regularly walk around with ‘hickeys on her neck.’
‘The girlfriend thing was well known,’ she said. ‘And in prison it’s very common especially for people in her life sentence situation and especially with the younger girls.’
Shirilla herself previously told The Daily Mail that she believed she was the victim of a ‘wrongful conviction.’
She is serving two concurrent sentences of 15 years to life, and has recently landed a prison job as a food service worker after complaining that there was ‘literally nothing’ for her to do behind bars.
