- The Ohio Supreme Court has denied Mackenzie Shirilla's appeal requesting a new trial after she was convicted of murder in 2022.

- The court affirmed a decision made in March by an appeals court, which noted Shirilla's lawyers missed the deadline to file a post-conviction appeal by a single day.

- The crash that killed Shirilla's boyfriend, Dominic Russo, and their friend, Davion Flanagan, as well as the resulting trial that ended in her conviction, are explored in the recent documentary, *The Crash*.

The Ohio Supreme Court has denied Mackenzie Shirilla's appeal for a new trial, after she was convicted of murder in 2023.

The ruling handed down on Tuesday affirmed the judgment of a May 2025 hearing presided over by Cuyahoga County judge Nancy Margaret Russo, the same judge who found Shirilla guilty of murdering her boyfriend, Dominic Russo (no relation) and their friend, Davion Flanagan, in a 2022 car crash. Shirilla's lawyers took that judgment to the Eighth District Court of Appeals, which upheld Russo's decision, as the Supreme Court did again on Tuesday.

The single-line ruling from the Supreme Court read: "Upon consideration of the jurisdictional memoranda filed in this case, the court declines to accept jurisdiction of the appeal pursuant to Rule 7.08(B)(4)."

Judge Anita Laster Mays, who presided over the appeals court hearing on the Shirilla case, offered deeper insight into Russo's initial judgment in denying the petition for post-conviction relief in her journal entry and opinion.

The appeals court first affirmed Shirilla's convictions on direct appeal, with trial transcripts being filed on Oct. 23, 2023. In Ohio, defendants are given 365 days to challenge their conviction after such transcripts are filed. But according to Mays, "Shirilla filed a petition for postconviction relief... on Oct. 24, 2023. The trial court dismissed the petition as time-barred on May 1, 2025, concluding it was filed one day past the 365-day jurisdictional deadline."

According to court records, Shirilla's defense team argued that because 2024 was a leap year, the single-day delay in filing should not be considered erroneous. Neither the appeals court nor the state's Supreme Court agreed.

On July 31, 2022, Shirilla, then 17, drove her car into a brick wall at nearly 100 mph. Passengers Russo and Flanagan were pronounced dead at the scene, while Shirilla survived after sustaining several injuries.

During the trial, prosecutors were able to produce evidence such as surveillance videos, vehicle "black box" data, and witness testimony that Shirilla intentionally caused the crash. She was ultimately sentenced to life in prison with an eligibility for parole after 15 years served.
