Ohio Supreme Court Declines Review for Woman Convicted in Fatal High-Speed Crash

Mackenzie Shirilla remains incarcerated at the Ohio Reformatory for Women following a series of unsuccessful legal challenges to her life sentence for a high-speed crash that killed two people. Shirilla, now 22, was convicted of murder after a judge determined she intentionally drove her vehicle into a building at 100 mph, killing her boyfriend, Dominic Russo, and his friend, Davion Flanagan. At the time of sentencing, the judge stated that Shirilla had acted with "precision" on a "mission" of death.

Court records show that the Ohio Eighth District Court of Appeals upheld Shirilla’s conviction in September 2023. Subsequent efforts for post-conviction relief were denied in October 2024 because the petition was filed after the statutory deadline. Most recently, the Supreme Court of Ohio declined to review her appeal in May 2025. Shirilla is currently scheduled to become eligible for parole on Oct. 29, 2037.

Shirilla’s parents, Steve and Natalie Shirilla, continue to maintain her innocence, arguing that the prosecution lacked evidence of prior calculation or intent. Steve Shirilla told reporters that the case relied on "five seconds of black box information" and suggested the charges should have been vehicular homicide. During her 2023 sentencing, Mackenzie Shirilla apologized to the victims' families, stating she did not cause the crash on purpose and could not remember the events of the collision.

The families of Russo and Flanagan have described the ongoing appeals process as a recurring trauma. Scott Flanagan, Davion’s father, stated in public posts that the repeated hearings force the families to relive the loss of their sons. Christine Russo, Dominic’s sister, noted that the family continues to struggle with the loss as they navigate the legal proceedings, which she described as a constant reminder of the tragedy.
