CLEVELAND, OHIO — Mackenzie Shirilla has suffered another major setback in her effort to overturn the convictions stemming from the deadly 2022 Strongsville crash.

On September 1, 2026, the Ohio Supreme Court formally denied Shirilla’s motion asking the state’s highest court to reconsider its earlier decision not to hear her post-conviction appeal.

The ruling closes another door in Ohio’s state court system.

But it does not end Shirilla’s broader attempt to challenge her conviction.

Her attorneys have already taken the fight into federal court.

⚖️ THE OHIO SUPREME COURT SAID NO
The latest ruling is extremely brief.

The court’s official entry states simply that Shirilla’s motion for reconsideration is denied.

Two justices, Patrick DeWine and Jennifer Brunner, dissented from the decision. The majority did not issue a separate opinion explaining the denial.

The decision leaves in place an earlier ruling from the Eighth District Court of Appeals.

That court had upheld the dismissal of Shirilla’s post-conviction petition after finding that it was filed outside Ohio’s statutory deadline.

The problem came down to a surprisingly narrow procedural issue.

Her petition was considered one day late.

📅 ONE DAY BECAME A MAJOR LEGAL OBSTACLE
Shirilla’s attorneys challenged the way the 365-day filing period had been calculated.

They argued that the clock should have been measured differently because of when a transcript connected to her juvenile proceedings became available.

The defense also raised arguments involving the leap year and the timing of the court records.

The lower appellate court rejected those arguments and ruled that the filing deadline had passed.

The Ohio Supreme Court then declined to take the case in June.

Shirilla’s lawyers asked the justices to reconsider.

The court’s September decision means that request has now failed as well.

🚗 THE CASE GOES BACK TO A CRASH IN 2022
The underlying case began on July 31, 2022, when Shirilla was 17 years old.

She was driving a Toyota Camry carrying her boyfriend, Dominic Russo, 20, and his friend, Davion Flanagan, 19.

The vehicle crashed into a brick building in Strongsville.

Both passengers died.

Shirilla survived.

Prosecutors argued that she deliberately accelerated to roughly 100 mph and intentionally drove into the building.

A judge convicted her in 2023 after a bench trial and sentenced her to 15 years to life in prison.

The two life-eligible sentences are being served concurrently.

🧠 HER DEFENSE HAS LONG QUESTIONED WHAT HAPPENED INSIDE THE CAR
Shirilla’s attorneys have continued to argue that the original trial did not adequately explore a possible medical explanation for the crash.

One of their arguments involves postural orthostatic tachycardia syndrome, or POTS, a condition that can cause dizziness, fainting and loss of consciousness.

The defense has argued that her original lawyers failed to properly investigate or present medical evidence that could have supported the possibility that she blacked out.

That theory directly challenges the prosecution’s conclusion that the crash was an intentional act.

The courts, however, have never ruled that the medical theory proves Shirilla actually lost consciousness before the collision.

The latest Ohio Supreme Court decision did not resolve that factual dispute.

It rejected her request for reconsideration.

🔎 HER ATTORNEYS ARE NOW TURNING TO FEDERAL COURT
This is where the story becomes more complicated.

Although Shirilla has now exhausted her current state-level appeal route, her attorneys filed a federal habeas corpus petition in July.

That petition asks a federal court to overturn her conviction and grant her a new trial.

The filing raises several constitutional arguments, including claims of ineffective assistance of counsel.

Among the allegations is that her original defense team failed to present potentially important evidence, including material concerning a previous incident involving Russo and the vehicle.

Her lawyers have also renewed their argument that evidence related to POTS should have been properly developed before the original trial.

That federal proceeding is separate from the state appeal the Ohio Supreme Court has now rejected.

🎬 THE CASE RETURNED TO THE SPOTLIGHT THIS YEAR
Shirilla’s legal battle has also gained renewed public attention following the release of Netflix’s documentary “The Crash.”

The film revisits the fatal collision, Shirilla’s conviction and the competing explanations for what happened that morning.

It also gives viewers access to interviews and material that have brought the case back into the national true-crime conversation.

The renewed attention has created a strange contrast.

Public interest in the case has increased at almost exactly the moment Shirilla’s state appeals have narrowed dramatically.

⚠️ THE STATE COURT RULING DOES NOT MEAN THE FEDERAL CASE HAS BEEN LOST
That distinction is important.

The Ohio Supreme Court’s latest decision means Shirilla’s current state post-conviction route has reached its end.

It does not mean a federal judge has rejected her habeas petition.

That case is still pending.

Her attorneys will therefore have another opportunity to argue that constitutional violations occurred during the original proceedings.

Whether a federal court agrees is an entirely separate question.

💔 RUSSO AND FLANAGAN’S FAMILIES HAVE ALREADY LIVED THROUGH YEARS OF LITIGATION
For the families of Dominic Russo and Davion Flanagan, the legal fight has stretched across years.

They lost the two young men in a crash that prosecutors said was deliberate.

Shirilla has consistently disputed the conclusion that she intentionally killed them.

The latest ruling does not change the original finding of guilt.

It simply removes another state-court avenue for challenging that finding.

🚨 HER FIRST PAROLE OPPORTUNITY IS STILL YEARS AWAY
Shirilla remains incarcerated at the Ohio Reformatory for Women.

Under her sentence, she will not be eligible for parole until 2037.

That means even a successful legal challenge remains the more immediate route for dramatically changing her situation.

For now, she remains in prison under the sentence imposed after her 2023 conviction.

🏛️ THE COURTS HAVE NOW DRAWN A CLEAR LINE — BUT THE CASE ISN’T FINISHED
The latest Ohio Supreme Court decision resolves one question:

Shirilla’s state post-conviction petition cannot be revived through another request for reconsideration.

But the larger question remains unresolved in federal court.

Did her original defense adequately investigate her medical condition?

Were potentially important pieces of evidence left out?

And did any alleged constitutional errors affect the outcome of the trial?

Those are the issues her federal petition now seeks to raise.

For the moment, however, the conviction remains intact.

The Ohio Supreme Court has said no.

The lower appellate court has already said no.

And Shirilla remains behind bars.

But the legal battle has not completely disappeared.

The state courts may have closed their door. Federal court is now where her next challenge will be decided.
