Mackenzie Shirilla, then 17, deliberately crashed her Toyota Camry into a brick warehouse wall in Strongsville, Ohio, at 5:45 a.m. on July 31, 2022, killing her 20-year-old boyfriend Dominic Russo (front-seat passenger) and his 19-year-old friend Davion Flanagan (rear seat). The vehicle was traveling 100 mph in a 35-mph industrial zone; black-box data showed the accelerator floored for the final 4–5 seconds and zero braking applied.
- Pre-planning: Phone GPS placed Shirilla at the exact crash site on July 29, two days prior.
- Toxic relationship: Texts and videos showed escalating abuse; Shirilla had threatened to crash the car with Russo inside multiple times, once telling a friend, “I’m going to kill him.”
- Post-crash behavior: While Russo and Flanagan died instantly, Shirilla survived (airbag deployment). She later told police she “blacked out” and remembered nothing, but toxicology showed no drugs or alcohol.
- Digital trail: A July 30 video on her phone captured her driving 100+ mph while smoking marijuana and saying, “I’m gonna get him so f—ed up.”
Trial & Sentencing
- Charges (Cuyahoga County, Aug 2023): 4 counts of murder, 4 counts aggravated vehicular homicide, 2 counts drug possession, 1 count felonious assault.
- Verdict: Judge Margaret McCollum found her guilty on all counts in a bench trial, calling the act “literal hell on earth” for the victims.
- Sentence: 15 years to life (concurrent on all counts), eligible for parole at age 32. The judge noted Shirilla showed zero remorse.
Victim Impact
- Russo’s mother described Dominic as a “gentle giant” trying to leave the relationship.
- Flanagan, an aspiring chef, was “in the wrong place at the wrong time.”
Current Status (Nov 2025)
Shirilla, now 20, is housed at Ohio Reformatory for Women. Her appeal (filed Oct 2023) claiming insufficient evidence and excessive sentence remains pending before the 8th District Court of Appeals.
