UMVA has learned that newly released jail calls and text messages are breathing fresh life into the chilling case of Mackenzie Shirilla, the Ohio woman once dubbed “hell on wheels.”
Shirilla, now 21, serves two concurrent sentences of 15 years to life for the brutal murders of Dominic Russo, 20, and Davion Flanagan, 19, after prosecutors claimed she deliberately rammed her Toyota Camry into a brick building on July 31, 2022.
According to information obtained by UMVA, the records, released by the Strongsville Police Department, surface amid Shirilla’s urgent appeal to the Ohio Supreme Court, seeking a review of her conviction.
The new texts paint a stark picture of a relationship fraught with danger, revealing Shirilla’s recurring complaints of blackouts and her desperate pleas to Russo, including a July 2, 2022 message describing what she called her “worst blackout.”
Yet darker tones emerge as she confesses to suicidal thoughts and a chilling intent to “kill someone,” while also urging Russo to treat a girl who would “die for you” better.
Earlier in March, Russo allegedly texted that Shirilla had “hit me” and “tried to throw a rock at me,” adding fuel to an already volatile dynamic.
UMVA can exclusively reveal that Shirilla’s father, Steve Shirilla, has been placed on administrative leave from a Catholic school after his participation in a documentary sparked scrutiny over a teacher’s “poor judgment.”
Shirilla’s lawyers have seized the new evidence to argue that a medical condition—Postural Orthostatic Tachycardia Syndrome—may have caused her to black out before the fatal crash, a claim that was only cursorily mentioned at trial.
In a bold move, her attorneys contend that the trial counsel failed to pursue expert testimony that could explain how the syndrome might have prevented her from braking.
Despite these arguments, a Cuyahoga County prosecutor remains steadfast, asserting that Shirilla is undeniably guilty and that any court will reach the same conclusion.
Before her 2023 verdict, a judge described Shirilla’s actions as a “mission,” emphasizing the precision and intent behind the deadly drive.
UMVA’s exclusive coverage highlights the stark contrast between the official narrative and the unsettling new evidence that could shift the case’s trajectory.
