The Unthinkable Crash
On July 31, 2022, a horrific scene unfolded in Strongsville, Ohio. 17-year-old Mackenzie Shirilla crashed her vehicle into a brick wall, instantly killing her boyfriend, 20-year-old Dominic Russo, and his friend, 19-year-old Davion Flanagan. Shirilla herself was critically injured, but what initially appeared to be a tragic accident would soon reveal a far more sinister truth.
First responders found both young men deceased at the crash site, while Shirilla was rushed to a nearby hospital for emergency treatment. As investigators began to piece together the events of that fateful morning, a dark, unsettling narrative started to emerge—one that pointed not to misfortune, but to malicious intent.
A Volatile Romance
Mackenzie Shirilla and Dominic Russo had been dating for four tumultuous years. Their relationship was reportedly riddled with conflict, characterized by frequent breakups and reconciliations. Dominic’s family described it as deeply troubled, marked by claims of Shirilla’s abusive behavior toward him.
Just weeks before the crash, disturbing incidents painted a grim picture of their dynamic. Dominic's mother recalled a desperate phone call from her son, after which a family friend witnessed Shirilla screaming, "I'm going to wreck this car right now" and attempting to hit Dominic. Another video filmed in July 2022 showed Shirilla threatening to break into his house.
The Social Persona
At Strongsville High, Shirilla was known for her vibrant social media presence and an "influencer" lifestyle, with classmates comparing her to the character Regina George from the movie "Mean Girls." She cultivated a significant following on TikTok, often receiving products from companies for review.
Davion Flanagan, the third passenger, was a mutual friend and former school athlete. Adopted at eight years old, Davion had navigated a difficult childhood, finding a semblance of normalcy in his friendships with Dominic and Mackenzie.
The Fateful Night
On the evening of July 30, 2022, hours before the crash, the trio attended a graduation party. Later, they moved to a friend's house, where they spent time listening to music and smoking marijuana, staying until the early hours of July 31.
Around 5:30 AM, they left the friend's house. Surveillance footage captured Shirilla's 2018 Toyota Camry slowly turning right from Pearl Road onto Progress Drive at precisely 5:34 AM. What happened next would change everything.
Just one minute later, a second camera recorded the Camry speeding, its lights on, as it crossed a T-split with Alameda Drive. The car slammed directly into the brick wall of a Plidco building, traveling at over 100 miles per hour, with the impact hitting the passenger side—where Dominic Russo was seated.
First responders arrived 45 minutes after the crash, describing the vehicle as "split in two"—the worst car crash an officer had ever seen. Shirilla was found unconscious, her foot still pressed firmly on the accelerator pedal. Psilocybin mushrooms and a digital scale were also discovered in her possession.
A Shocking Lack of Remorse
While hospitalized for her severe bone fractures, Shirilla's social media activity continued to draw attention. She posted videos from her hospital bed, and surprisingly, her TikTok popularity surged, with modeling agencies even reaching out to her.
Even more unsettling were her subsequent posts: a satirical TikTok declaring, "I'm just one of those girls that can do a lot of drugs and not die," and photos of Russo and Flanagan dressed as corpses for Halloween. This disturbing behavior immediately raised suspicion among Davion’s family members.
Unraveling the 'Accident'
Initially, detectives leaned towards classifying the crash as an accident, but doubts quickly surfaced. A mechanics expert confirmed the Camry was fully operational and its brakes worked perfectly, ruling out any mechanical failure. When interrogated, Shirilla claimed she blacked out and had no memory of the incident.
Police soon began to suspect premeditated murder-suicide, theorizing Shirilla crashed the car because she didn't want Dominic to break up with her again. Crucially, GPS data from her devices revealed she had visited that exact industrial area just three days before the incident—a chilling revelation suggesting a dry run.
The Verdict
On November 4, 2022, with sufficient evidence gathered, Shirilla was arrested shortly after her discharge from the hospital. She was charged with 17 crimes, including two counts of aggravated murder. Bodycam footage captured her crying during the arrest, yet she appeared to attempt relaxation in the police cruiser.
Shirilla’s lawyer opted for a bench trial, placing her fate in the hands of a judge rather than a jury. On August 14, 2023, Judge Nancy Margaret Russo (no relation to Dominic) found her guilty on all counts, including murder, aggravated vehicular homicide, and felonious assault.
Judge Russo unequivocally declared Shirilla's actions premeditated, famously calling her "hell on wheels." Prosecutors highlighted Shirilla's post-crash social media behavior, including her Halloween posts, as compelling evidence of a chilling lack of remorse.
Dominic Russo and Davion Flanagan's family members delivered powerful victim impact statements, advocating for the maximum sentence. On August 21, 2023, Shirilla was sentenced to two concurrent life terms in prison, with the possibility of parole after 15 years. Her driver's license was permanently suspended.
Appeals and Aftermath
Shirilla's legal team filed multiple appeals, citing insufficient evidence and clerical errors, but these were denied. As of 2025, she remains incarcerated at the Ohio Reformatory for Women, with her parole hearing scheduled for 2038.
In the wake of this profound tragedy, friends and family created a small memorial at the crash site. The Davion Flanagan Memorial Scholarship was also established, honoring Davion's memory by providing educational support to aspiring barbers.
The sensational nature of the case captivated public attention, becoming the subject of numerous true crime documentaries and podcasts across platforms like YouTube, Court TV, Investigation Discovery, and Channel 4. It even sparked an op-ed discussing the decline of traditional values, solidifying Shirilla's name "into the annals of a society" as one commentator put it.

Mackenzie Shirilla, born August 2, 2004, was 17 years old at the time of the crash.

Prior incidents
Murder of Dominic Russo and Davion Flanagan
On March 23, 2020, the police and fire departments responded to a suicide threat by a 15-year-old female at the Shirilla home. According to the police report, Shirilla was not taken to a hospital because her parents did not "think her threats are real" and did not "believe she will hurt herself." Shirilla's mother, Natalie, testified in court that she had never perceived her daughter to be suicidal.
According to Russo's brother, the couple had frequent conflicts and had broken up and reunited multiple times. He told investigators that he had witnessed Dominic calling Shirilla's parents to pick her up because she would not leave his home. A video Dominic Russo filmed days before the crash showed Shirilla threatening to break into his house and key his car.
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. Two weeks prior to the crash, Russo had called his mother asking for help because Shirilla was driving erratically. She sent a family friend to pick Russo up, who later told police he heard Shirilla screaming: "I'm going to wreck this car right now!" and saw Shirilla hitting Russo with her hands.
Car crash and investigation
Murder of Dominic Russo and Davion Flanagan
On July 30, 2022, Shirilla, Russo, and Flanagan spent time together in the 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. At 11:00 p.m., the trio drove to the house of their friend Paul Burlinghaus, where they listened to music and smoked marijuana. They stayed there until early morning on July 31, leaving at 5:30 a.m.
At 5:34 a.m., a CCTV camera captured Shirilla's 2018 Toyota Camry slowly turning right from Pearl Road onto Progress Drive. One minute later, a second camera captured the car speeding with lights on at the end of Progress Drive. It crossed the T-split with Alameda Drive, and accelerated into the Plidco building, with the passenger side of the vehicle colliding with a corner of the structure. On the 2022 Google Earth Street View, the impact site could still be seen as a blue plastic sheet covering the wall. The car was traveling at over 100 miles per hour (160 km/h) when it crashed.
First responders arrived at the scene 45 minutes after the crash to find Russo, Flanagan, and Shirilla unconscious. Shirilla was taken to a nearby hospital while Russo and Flanagan were pronounced dead at the scene. Police found psilocybin mushrooms and a digital scale in Shirilla's possession.
Russo was sitting in the passenger seat of the vehicle at the time of the crash, with Flanagan sitting in the back. 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. She also posted satirical TikTok videos; one showed her saying, "I'm just one of those girls that can do a lot of drugs and not die".
The Halloween after the crash, Shirilla and her friends posted to social media, posing in face paint that made them resemble corpses. (This was later shown in court.) Although a friend of Shirilla's claimed they were dressed as rapper Playboi Carti, Flanagan's sister thought Shirilla's behavior to be callous so soon after the deaths of her friends, and raised her suspicions about the events. The victims' families requested that the police investigate the matter more closely.
Police initially thought the crash was an accident or possibly had happened due to tampering with the vehicle. However, an auto expert found the vehicle was in perfect working condition before the crash. The onboard computer systems indicated the accelerator was being pressed at the time of the crash, with no use of the brakes.
When interrogated, Shirilla claimed she had blacked out during the crash and had no memories of the incident. Her lawyer claimed that Shirilla suffered from POTS, a blood-circulation condition that can cause momentary blackouts.
However, police soon began to believe she had intentionally crashed her vehicle. At her trial, the prosecutor noted that the vehicle had passed through a slight right/left "dogleg" intersection at high speed before the crash, which required conscious steering action by somebody able to reach the wheel. 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.
Arrest, trial and incarceration
Murder of Dominic Russo and Davion Flanagan
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, including two counts of aggravated murder and one count of drug trafficking.
Shirilla chose a bench trial, in which a judge determines a person's guilt, rather than a jury trial. On August 14, 2023, Shirilla was found guilty by the Cuyahoga County Court of Common Pleas on charges of murder, felonious assault, aggravated vehicular homicide, drug possession, and criminal tools possession. Judge Nancy Margaret Russo (no relation to Dominic Russo) said that Shirilla's actions were premeditated, calling her "hell on wheels". Prosecutors said Shirilla had no remorse and used social media videos of her dancing on Halloween as evidence.
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. She received two life sentences, one each for the murders of Russo and Flanagan, to be served concurrently. The judge also permanently suspended her driver's license. After the sentencing, Cuyahoga County Prosecutor's Office released a statement 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.
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.
They filed a second appeal on April 24, 2025. Judge Russo also denied this appeal due to it being filed untimely.
In March 2026, the Eighth District Court of Appeals upheld Judge Russo's decision to deny her appeal. Shirilla is currently incarcerated at the Ohio Reformatory for Women. Shirilla will be eligible for parole in October 2037.

On May 14, 2026, Shirilla's father told NBC News that they believe she is innocent and was "falsely accused of something." He said there was insufficient evidence to convict her of murder and she should have instead been charged with vehicular homicide. Shirilla's mother said their daughter did not receive a fair trial because her lawyer did not use all the information the family provided to defend her.
Mackenzie Shirilla appears in the documentary The Crash, interviewed by creators Gareth Johnson and Angharad Scott. Her lawyer was present, and she repeated her previous claim of not being able to remember the incident. She said, "I have no recollection of that morning, but I know nothing about it was intentional, because that's not in my character". Shirilla also claimed that she had no intention of causing the accident, saying she was not innocent, but not a murderer either.
