STRONGSVILLE — The Ohio Supreme Court rejected Mackenzie Shirilla's latest appeal for a new trial in May 2025, upholding her 2023 conviction for a fatal 2022 car crash in Strongsville, Ohio. The court's ruling stated, "Upon consideration of the jurisdictional memoranda filed in this case, the court declines to accept jurisdiction of the appeal."

Shirilla is currently serving a sentence of 15 years to life in prison. She was convicted in 2023 on charges related to a car crash that occurred on July 31, 2022, when her sedan struck a building in Strongsville, Ohio, at approximately 100 mph. Dominic Russo, 20, and Davion Flanagan, 19, died in the crash. Shirilla was the sole survivor.

Shirilla's lawyers argued in their appeal that she suffers from a pre-existing medical condition that caused her to black out before the crash. Her attorneys contended that her previous defense team failed to investigate or support this alleged condition with expert testimony. Additionally, Shirilla filed a motion for postconviction relief 366 days after the trial transcript was filed.

The Eighth District Court of Appeals denied Shirilla's motion because it was filed one day past the deadline under Ohio state law. Shirilla then argued to the Supreme Court that she should have received additional time to file her motion, stating that transcripts from a juvenile court hearing were filed several months after the trial transcripts. In May 2025, Cuyahoga County Judge Nancy Margaret Russo ruled that Shirilla's petition for a new trial was invalid. During Shirilla's sentencing, Judge Russo described Shirilla using profane language.

Ohio Supreme Court Justice Pat DeWine dissented from the decision not to take the case. Shirilla is incarcerated at the Ohio Reformatory for Women and will be eligible for parole in October 2037. Her case was the subject of the Netflix documentary "The Crash."
