The Ohio Supreme Court has rejected convicted killer Mackenzie Shirilla’s latest attempt to overturn her conviction and secure a new trial in the high-profile 2022 crash that killed her boyfriend and a close friend.

Shirilla, now 21, is serving a sentence of 15 years to life after being convicted of intentionally slamming her car into a building at 100 mph in Strongsville, Ohio, in July 2022. The crash killed her 20-year-old boyfriend, Dominic Russo, and their 19-year-old friend, Davion Flanagan. Shirilla was the only survivor.

In a brief ruling issued Tuesday, the state’s highest court declined to accept jurisdiction over her appeal, effectively ending her latest legal challenge. “Upon consideration of the jurisdictional memoranda filed in this case, the court declines to accept jurisdiction of the appeal,” the order stated.

Shirilla’s attorneys had argued that she suffers from a pre-existing medical condition that may have caused her to black out before the fatal crash. They claimed her original defense team failed to properly investigate the condition or present supporting expert testimony during her 2023 trial. This marked her second attempt to win a new trial; her first appeal was also denied.

During her non-jury trial, Cuyahoga County Judge Nancy Margaret Russo convicted Shirilla on four counts of felonious ᴀssault and two counts of aggravated vehicular homicide. In a scathing statement at sentencing, the judge described Shirilla as “literal hell on wheels,” a phrase that quickly became ᴀssociated with the case.

The case gained national attention and was the subject of the Netflix documentary “The Crash.” Prosecutors argued that Shirilla deliberately crashed the vehicle, while the defense maintained the incident was a tragic accident.

Shirilla is currently incarcerated at the Ohio Reformatory for Women. According to reports, she recently began working in the prison’s food service. A former inmate previously claimed that Shirilla carries herself like a “queen bee” inside the facility and has been involved in romantic relationships with other inmates, leaving visible hickeys on her neck.

Her legal team had previously filed the latest peтιтion for a new trial on Oct. 24, 2024 — one day after the ᴅᴇᴀᴅline under Ohio law. In May 2025, Judge Russo ruled the filing invalid. That decision was later upheld by the Eighth District Court of Appeals.

Shirilla will become eligible for parole in October 2037.

The rejection of her latest appeal marks another significant setback for Shirilla, who has maintained her innocence and continues to seek ways to challenge her conviction. For the families of Dominic Russo and Davion Flanagan, the court’s decision brings a measure of finality, though the pain of losing their loved ones in such a violent and deliberate manner remains.

As Shirilla serves her sentence, the case continues to serve as a stark reminder of the devastating consequences of reckless and intentional actions behind the wheel.
