Public Statements and the 2023 Conviction

Since his daughter, Mackenzie Shirilla, was convicted on 12 felony charges—including murder—in 2023, her father, Steve Shirilla, has consistently served as one of her most vocal advocates. Mackenzie is currently serving two concurrent life sentences at the Ohio Reformatory for Women for her involvement in a July 2022 incident in Strongsville, Ohio, where she drove her vehicle into a brick structure at high speed, resulting in the deaths of her boyfriend, Dominic Russo, and her friend, Davion Flanagan.


The case recently returned to the spotlight following the release of the Netflix documentary The Crash. Throughout the documentary and various media appearances, Steve Shirilla has maintained his daughter’s innocence, echoing Mackenzie’s own claims that she has no recollection of the event.


Early Confrontations with Law Enforcement

Steve Shirilla’s public involvement began shortly after the incident. During early interactions with police, he was highly critical of how officers handled the investigation and his daughter's detainment. When officials noted that Mackenzie, then 18, could speak for herself, Steve retorted: «Yeah, but she’s a dumb 18-year-old.» He frequently demanded to speak with her, citing her legal counsel's instructions that she should not be questioned by police.


Additionally, he expressed frustration over the timing of her arrest, questioning why police did not coordinate with him to have her turn herself in. He also alleged that officers were monitoring his residence, though he did not provide further context regarding those claims.


Views on Marijuana and the Netflix Documentary

In The Crash, Steve Shirilla addressed findings that cannabis was in his daughter’s system at the time of the collision. His comments regarding the matter were as follows:

«I don’t have a problem with her smoking dope. If you’re going to smoke a drug, that’s the one I believe you should take.»

These remarks led to significant public backlash and his subsequent placement on leave from his teaching position at a local school. Later, Steve clarified his stance, stating that he was not advocating for drug use but rather reflecting on his inability to control his daughter’s personal choices as she reached adulthood.


Challenging the Prosecution’s Case

In appearances on podcasts such as True Crime This Week, Steve has argued that the prosecution's narrative is flawed. He pointed to the presence of Davion Flanagan in the vehicle as evidence against premeditated murder:

  • He contends that if Mackenzie were truly driven by a desire to harm her boyfriend, she would not have had another passenger in the car.
  • He continues to insist that a mysterious event occurred inside the vehicle that has yet to be explained.

Ongoing Appeals and Family Advocacy

Steve is joined by his wife, Natalie Shirilla, in his public defense of their daughter. Recently, Natalie stated that Mackenzie has never reviewed the discovery or evidence related to her case, describing her daughter as being «trapped in a nightmare.»


Mackenzie’s legal team has repeatedly attempted to appeal the conviction, citing potential medical issues—such as a previous POTS diagnosis—that could have caused a loss of consciousness. However, the Ohio Supreme Court declined to hear the most recent appeal on June 23, 2026. Despite ongoing reports of disciplinary issues during her incarceration, Steve Shirilla maintains that the full story of what transpired that day has not yet been told.
