Mackenzie Shirilla’s fight to overturn her murder conviction has suffered another major setback. The Ohio Supreme Court has officially declined to hear the 21-year-old’s latest appeal, meaning the sentence that put her behind bars for the deaths of her boyfriend, Dominic Russo, and friend Davion Flanagan will remain in place. The ruling marks the latest defeat in a years-long legal battle that has kept one of America’s most controversial true crime cases in the spotlight.
Shirilla was convicted in 2023 after prosecutors argued she intentionally drove her vehicle into a brick building at nearly 100 mph during the early morning hours of July 31, 2022. The crash killed 20-year-old Dominic Russo and 19-year-old Davion Flanagan, while Shirilla survived with serious injuries. A judge later concluded the collision was deliberate and described it as a calculated act rather than a tragic accident.
Since her conviction, Shirilla has repeatedly attempted to challenge the verdict.
Her attorneys argued that she may have suffered from a pre-existing medical condition that caused her to lose consciousness behind the wheel, potentially explaining the deadly crash. They also sought post-conviction relief through multiple courts, but every effort has failed.
One of the biggest obstacles facing her legal team involved a filing deadline.
Court records show that a previous post-conviction petition was submitted one day late. Prosecutors argued that Ohio law clearly required the filing within 365 days after trial transcripts were entered into the record. Shirilla’s attorneys contended that a leap-year calculation contributed to the delay, but appellate judges ultimately rejected that argument.
After exhausting options in lower courts, Shirilla’s legal team asked Ohio’s highest court to review the case.
In an order signed by Chief Justice Sharon Kennedy on June 23, the Ohio Supreme Court declined to accept jurisdiction, effectively ending the latest appeal effort. The decision leaves Shirilla’s conviction and sentence intact.
As a result, Shirilla will continue serving two concurrent prison terms of 15 years to life at the Ohio Reformatory for Women. According to prison records cited by multiple reports, she will become eligible for parole in 2037, when she will be approximately 33 years old. Her projected release date is listed as October 29, 2037, though any release would depend on decisions made by the parole board.
The case has attracted renewed attention in recent months following the release of Netflix’s documentary The Crash, which explored competing narratives surrounding the incident. While Shirilla and her supporters continue to maintain that the crash was not intentional, prosecutors and the victims’ families have consistently argued that the evidence proved otherwise.
For now, the Ohio Supreme Court’s decision closes another chapter in the highly publicized case.
Unless new legal avenues emerge, Mackenzie Shirilla will remain behind bars as the families of Dominic Russo and Davion Flanagan continue to seek closure nearly four years after the crash that changed their lives forever.
