Newly released text messages and jail calls are casting fresh light on the case of Mackenzie Shirilla, the Ohio woman dubbed “hell on wheels,” as her murder conviction gains renewed attention following Netflix’s documentary series The Crash.

Shirilla, now 21, is serving two concurrent sentences of 15 years to life in prison for the deaths of her 20-year-old boyfriend Dominic Russo and 19-year-old Davion Flanagan. Prosecutors say she deliberately crashed her Toyota Camry into a brick building in Strongsville, Ohio, at over 100 mph on July 31, 2022, in what they described as a murder-suicide attempt to end her toxic relationship with Russo. Flanagan was an unintended victim who was in the car at the time.

“This was not reckless driving. This was murder,” Cuyahoga County Judge Nancy Margaret Russo said during sentencing. “She had a mission, and she executed it with precision. The mission was death.”

The Strongsville Police Department recently released thousands of text messages and jailhouse calls. Among them, Shirilla reportedly wrote messages such as “I’m gonna kill someone” and “THIS IS WHY I J WANNA F—ING KMS [kill myself].” Other texts revealed a volatile relationship, including Russo allegedly texting that Shirilla had hit him and tried to throw a rock at him.

Shirilla’s defense has long claimed she suffered a medical episode — possibly related to Postural Orthostatic Tachycardia Syndrome (POTS) — causing her to black out before the crash. Her attorneys argue that her trial lawyers failed to adequately investigate this condition.

Her case is now before the Ohio Supreme Court after a lower court rejected her appeal for being filed one day late. Her legal team is seeking review of whether her post-conviction claims regarding the medical defense should be heard.

The timing coincides with the May 15 release of Netflix’s The Crash, which has brought national attention back to the case. Shirilla’s father, Steve Shirilla, was placed on administrative leave from his job at a Catholic school after participating in the documentary.

Cuyahoga County Prosecutor Michael O’Malley’s office maintains that Shirilla is guilty of murder and is confident the conviction will stand.
