The murder of Dominic Russo and Davion Flanagan occurred on July 31, 2022, when Mackenzie Shirilla intentionally crashed her vehicle into a brick wall in Strongsville, Ohio, killing two passengers: her boyfriend, Dominic Russo, and his friend, Davion Flanagan.

Both Russo and Flanagan were pronounced dead at the scene, while Shirilla was seriously injured and taken to the hospital. Shirilla, who was 17 years old at the time of the crime, was later arrested and charged with the murder of Russo and Flanagan. In a 2023 bench trial, the judge concluded she intentionally crashed the car in an act of premeditated murder.^[2] Shirilla was convicted of 12 felony charges and sentenced to 2 concurrent life sentences, with the possibility of parole after 15 years. As of 2026^[update], she was incarcerated at Ohio Reformatory for Women. Multiple documentaries about the case have been made.

Mackenzie Shirilla was raised by her parents, Natalie and Steve Shirilla, in Strongsville, Ohio. At the time of the crash, Shirilla was a 17-year-old recent graduate of Strongsville High School. During her studies, Shirilla had met her boyfriend, Dominic Russo (20 years old), who had also graduated from the school by the time of the incident. Russo dated Shirilla for 4 years, starting when Mackenzie was only 13 and he was 16. According to Russo's brother, Shirilla and Russo had frequent conflicts and had broken up and reunited multiple times. The pair started living together in 2021, while Mackenzie was still underage. Russo's mother, Christine, said about six months before the crash the relationship between Russo and Shirilla experienced tension again, including multiple claims of Shirilla severely abusing Russo. For example, in July 2022, Russo called Christine in distress, and she sent a family friend to pick Russo up. The friend claimed to have seen Shirilla screaming; "I'm going to wreck this car right now" and trying to hit Russo with her hands. A video also filmed in July 2022 showed Shirilla threatening to break into Russo's house and key his car.^[3]

Classmates of Shirilla said she was a fan of Regina George, a cruel and domineering character from the movie Mean Girls, and liked to imitate her. Shirilla had an account on TikTok where she posted videos of her lifestyle and clothing. The account had a large number of followers, as well as several companies sending samples of clothing and products for review.^[4] Shirilla reportedly enjoyed living in the Russo residence, spending time with Russo's family, and driving her car through areas of Strongsville. Shirilla and Russo had a mutual friend, Davion Flanagan, who was 19 years old at the time of the incident. He was a school athlete who had been adopted at the age of eight by his guardian, Jaime Flanagan, due to drug abuse by his biological family.^[5]

On July 30, 2022, Shirilla, Russo and Flanagan attended several events hours before the crash. At approximately 10:15 p.m., they attended a graduation party held at the house of Kelly Vraja, one of Shirilla's friends. The trio spent less than an hour there before driving to the house of their friend Paul Burlinghaus at 11 p.m., where they listened to music and smoked marijuana. They continued spending time in the house until early morning on July 31, leaving at 5:30 a.m.^[3][5]

At 5:34 am, a CCTV camera captured Shirilla's car, which was a 2018 Toyota Camry, slowly turning right from Pearl Road into Progress Drive. One minute later, a second camera captured the car speeding with lights on at the end of Progress Drive crossing the T-split with Alameda Drive into the Plidco building, the corner of the brick wall exactly hitting the passenger side of the car. On the 2022 Google Earth Street View the impact site can still be seen as a blue plastic sheet covering this wall. The car was traveling at over 100 miles per hour (160 km/h) when it crashed.^[4][6]

First responders arrived at the scene 45 minutes after the crash to find Russo, Flanagan and Shirilla unconscious, with Shirilla's foot still pressing the accelerator pedal. Shirilla was taken to a nearby hospital while Russo and Flanagan were pronounced dead at the scene.^[7] Police found psilocybin mushrooms and a digital scale in Shirilla's possession.^[8][9]

Russo was sitting in the passenger seat of the vehicle at the time of the crash, with Flanagan sitting in the back.^[10] Responding officers are audible on body camera footage, one saying the car "split in two" and another describing it as the "worst" car crash that he had ever seen. Shirilla was severely injured and suffered multiple bone fractures. She was airlifted to a hospital where she underwent multiple surgeries. Witnesses said that she was "inconsolable" when she learned Russo and Flanagan died. Shirilla posted multiple videos about her time in the hospital, showing the interior of the medical ward. The popularity of her account peaked during her stay in the hospital. Shirilla showed videos of her sitting in a wheelchair attending concerts and posted satirical TikTok videos, one video showed her saying, "I'm just one of those girls that can do a lot of drugs and not die".^[4]

Shirilla also posted photos of herself and a couple of friends who had dressed as corpses during Halloween. Such behavior made Flanagan's sister suspicious and led to the victims' families requesting police investigate the matter more closely. Police initially thought the crash was an accident or possibly happened due to tampering with the vehicle. An auto expert said the vehicle was in perfect working condition before the crash, and onboard computer systems indicated the accelerator was being pressed at the time of the crash and there was no use of the brakes. Shirilla was interrogated and claimed she blacked out during the crash and had no memories of the incident. Police soon began to believe she had intentionally crashed her vehicle. They believed her intention in crashing the car was to commit murder-suicide because she did not want Russo to break up with her again. The police tracked GPS data from her devices and discovered she had visited the area near the crash scene three days before the incident, likely as preparation for the crash.^[4]

By November 4, 2022, the police had gathered enough evidence to arrest Shirilla shortly after her discharge from the hospital. She was charged with 17 crimes,^[4] including two counts of aggravated murder and one count of drug trafficking.^[11] A bodycam footage of the arrest was released in 2025, showing an officer handcuffing Shirilla as she was crying. While being transported to jail in a police cruiser, she was seen closing her eyes and seemingly trying to relax.^[12][13]

Shirilla's lawyer, James McDonnell, chose a bench trial, where a judge determines a person's guilt, rather than a jury trial.^[14] On August 14, 2023, Shirilla was found guilty by Cuyahoga County Court on charges of felonious assault, murder, aggravated vehicular homicide, drug possession, and criminal tools possession.^[15][16] Judge Nancy Margaret Russo (no relation to Dominic Russo)^[1] said that Shirilla's actions were premeditated, calling her "hell on wheels".^[7] Prosecutors said Shirilla had no remorse and used social media videos of her dancing on Halloween as evidence.^[14]

On August 21, 2023, the sentencing phase of the trial began. Davyne Flanagan, the sister of Davion Flanagan, asked the court to give Shirilla "the longest possible sentence". Christine Russo, Dominic Russo's mother, told Shirilla that she should be "thankful" she is still alive and has a future. Shirilla was sentenced to life in prison with the possibility of parole in 15 years.^[17] She received two life in prison terms, one for murdering Russo and another for killing Flanagan. They are to be served concurrently.^[18] The judge also permanently suspended her driver's license.^[14][19] After the sentencing, Cuyahoga County Prosecutor's Office released a statement^[9] saying that the murder was premeditated and that Shirilla intentionally drove the car at 5:30 a.m. due to the streets being relatively quiet in the late night and early morning hours.^[20]

On September 25, 2023, Shirilla's legal team filed an appeal, alleging that there was not enough evidence in the trial for the convictions and that multiple clerical errors were made during the trial. The appeal was denied.^[2] They filed a second appeal on April 24, 2025. Judge Russo also denied this appeal due to it being filed "untimely".^[21] On May 22, 2025, family of Shirilla were interviewed by WKYC. The family stated that they believe the crash to be unintentional.^[22] In March 2026, Eighth District Court of Appeals upheld Judge Russo's decision to deny her appeal.^[23]

Shirilla is currently incarcerated at Ohio Reformatory for Women.^[3] Her earliest eligibility for a parole hearing will occur in 2038.^[24]

Shortly after the news of the crash, friends of Russo and Flanagan created a small memorial near the crash site to show their support.^[25] Family of Davion Flanagan later created the Davion Flanagan Memorial Scholarship to provide educational support to "aspiring barbers" to honor his intention of becoming a barber.^[26]

Various companies and streaming services made documentaries about the incident. The case was featured in a podcast titled Hell on Wheels on YouTube, Court TV made a documentary about the murders on YouTube, and several videos detailing the case were also uploaded to the platform. True crime series Killer Cases analysed the case in season 4, episode 12 of the series, which aired on Channel 4 and Apple TV.^[27] It was also featured in a documentary by Investigation Discovery in 2025^[28] and an op-ed written by Republican politician Armstrong Williams in 2023, which talked about the decline of traditional values in the United States. He said that Shirilla's name had been "etched into the annals of a society".^[29] Another documentary titled The Crash streamed on Netflix on May 15, 2026, created by media company Raw owned by All3Media.^[30]
