Mackenzie Shirilla's lawyers made surprising claim in appeal as her third request denied
Mackenzie Shirilla's legal team made a surprising claim as the Supreme Court of Ohio has once again declined to hear an appeal, after she was convicted of murder in 2023.
Shirilla has attempted to appeal her murder case a total of three times, twice in Cuyahoga County Common Pleas Court and once in the Eighth District Court of Appeals, all of which have been denied by the Supreme Court.
The young woman from Ohio was just 17 years old when she purposely smashed her vehicle at 100mph into a brick wall in 2022, killing her boyfriend, Dominic Russo, 20, and their friend, Davion Flanagan, 19, who were in the passenger seats.
And while Shirilla claims that she had suffered a medical emergency behind the wheel that led to the fatal crash, a judge ruled in 2023 that it was 'controlled, methodical, deliberate, intentional, and purposeful' murder, and was consequently handed two concurrent life sentences.

A Netflix documentary titled The Crash revisits the infamous case that divided the nation, in which Shirilla speaks out publicly for the first time since her conviction.
But during her attorney's attempt to appeal the case for the third time, they made a surprising claim about the 21-year-old's state during the collision.
After filing the appeal on April 27, they claimed: "There is medical evidence that Mackenzie Shirilla suffered from a pre-existing medical condition that could have caused her to black out while driving."
Her attorneys wrote in the appeal that the trial court dismissed her petition for post-conviction relief because it was filed after the deadline.
And in response to the appeal, the court argued that Shirilla 'miscalendared' the due date.
The court found: "The trial transcripts were filed in her direct appeal on October 23, 2023, triggering the 365-day statutory clock to file the petition.
"Shirilla filed her petition on October 24, 2024, which is the same day that many of her exhibits were notarized.
"Because 2024 was a leap year, Shirilla's petition was late by one day. The trial court properly denied her petition as untimely."
When delivering the verdict in court in 2023, the judge stated: "This was not reckless driving - this was murder.
"She had a mission, and she executed it with precision. The decision was death."
The young woman remains incarcerated in the Ohio Reformatory for Women, where she is expected to have her first parole board hearing in September 2037.
