The release of the Netflix documentary The Crash has turned heads over the past week, with viewers shocked at the murder case involving Mackenzie Shirilla.
In the early hours of July 31, 2022, when Mackenzie was just 17, she was arrested after being at the wheel of a car that crashed into a brick wall at over 100 mph, killing the two passengers onboard.
She would eventually be found guilty of killing two men after intentionally crashing in the premeditated murders of Dominic Russo and Davion Flanagan, according to a judge.
Mackenzie was then convicted of 12 felony charges, which included four counts of murder, four counts of felonious assault, two counts of aggravated vehicular homicide, one count of drug possession, and one count of possessing criminal tools.
The teen was sentenced to two concurrent life sentences, with the possibility of parole after 15 years, in 2023.
This year, the case is back in the limelight with Netflix's release of The Crash, though Mackenzie claims she cannot remember the incident.
The convict was interviewed in prison, while documentary-makers also spoke to her loved ones, as the true crime film included a good chunk of information in relation to the case.
However, some details were left out of the final cut, which could add more layers to the chilling story.
So, here are the six missing details from The Crash.
While the documentary featured interviews with some of Mackenzie's classmates who supported her, it turns out that this wasn't the entire truth.
In an episode of the true crime series Mean Girl Murders, titled Under the Influence, Mackenzie's murder case is the focus.
As part of the Hulu doc, many of Mackenzie and Dominic's classmates weren't as supportive, with the convict's former friend Rachel Anderson claiming: "Mackenzie, she wanted the likes, she wanted the followers, she wanted to be at the top.
"Mackenzie gets what she wants, Mackenzie is never punished, and now Mackenzie is punished, and there's nothing Mackenzie or her family can do."
Another former friend, Jaina Maynard, added that she was simply "terrible to people," claiming that she could have "been a lot more if she just chose a different route and got the help she needed."
The Crash didn't include an audio recording taken by police between Mackenzie and her mom, Natalie Shirilla.
Speaking in a "unique language" which authorities thought to be pig latin, it sounded like Mackenzie was asking her mom to do her a favor.
Detective Zaki Hazou revealed that they are investigating the teenager for aggravated vehicular homicide, which was when Mackenzie started speaking to her mom in the odd language.
Police later claimed they knew what the translation was, alleging that she said: "Can we tell the police I had a seizure, can we tell the police something like that?”
Mackenzie then asked the detective if they can "just take my license away for like, 10 years," instead.
This piece of evidence was crucial in getting the teen thrown behind bars, though her lawyers argued that she suffered a medical event before the crash.
They claimed she had passed out due to postural orthostatic tachycardia syndrome (POTS), though there was no proof of a diagnosis.
Speaking in court, first responder Brett Stanislaw said that Mackenzie's vitals were normal, "which he said ruled out a stroke, seizure or other significant neurological emergency," court documents say.
The Russo family checked in on Mackenzie after the crash, but Christine, Dominic's sister, says that Mackenzie's mom lied about her condition.
Speaking in a May 11 video posted to her channel, The Big Sister: Unhinged, she said: "We thought it was an accident for a while, and we were really, really worried about Mackenzie and how she was doing,
"We were seeing how she was for about three days; her mother told us that she was unconscious and hadn't woken up."
Apparently, this was due to Natalie being "terrified" of telling the family how Dominic and Davion had died, as Christine added: "Natalie told me, my dad and my sister for days that she was unconscious,
"And now looking back, she was waiting to form her story," she alleged.
Police would find Mackenzie unconscious and not breathing, as she was taken to the ER for treatment.
There is no record that she was unconscious for three days, and the convict even posted snaps from the hospital during treatment, say NBC News.
A lot of the Netflix doc focuses on the messy relationship between Mackenzie and Dominic, which meant that the life of Davion fell into the background.
But Davion was a talented football player who would be forced to pursue other goals due to injuries, and had aspirations to go to barber school and own his own barbershop one day.
His parents, Jaime and Scott Flanagan, started a fundraiser with the aim of helping low-income aspiring barbers to attend school.
Speaking to People in 2023, Jaime said: “The amount of good that could be done in Davion's name and the impact that he could still have on the world is something that gives us some joy and hope in the middle of all of this sadness and devastation.”
Scott said that helping even one person would "truly" be a blessing - as of May 21, 2026, the scholarship fund has raised over $90,000.
This may be the most groundbreaking claim yet, as Mackenzie was told that Dominic and Davion had died while she was in the hospital.
Court documents revealed that the doctor noted that she felt "depressed and felt grief, guilt and shame."
It further read that: "She said she 'wanted to die' and expressed that it was 'her fault for killing her boyfriend.'"
Mackenzie even texted Dominic's brother, Angelo, after the crash, with police eventually getting a hold of these messages.
One of these from August 2022 read: “I know you probably think this is all my fault ... I wish that he was here, too.
“This should have never happened ... I really do feel bad. It's killing me.”
Almost a year after the death of Mackenzie's ex-boyfriend, his gravesite was reportedly burned to the ground, according to a GoFundMe update from Christine in June 2023.
She posted a photo of the burnt gravesite, writing: "His grave was set on fire, and everything burned to the ground,
"Nothing was salvageable except a cement cross. Most of the items were irreplaceable (flowers and ribbon from his funeral, letters from his nieces and nephews and friends and siblings and parents, stuffed animals, things that can't be replaced)."
She asked for donations to reach a $10k goal to restore the site, but within two months and a few thousand dollars, she updated donors with good news, as they managed to recreate the gravesite.
Christine wrote on the page in August 2023: "Just wanted to say thank you for all of your generous donations,
"We were able to recreate Dom's grave beautifully. Any further donations will go to purchasing updated memorial items, flowers, etc. in the future. Or maybe a nice custom bench, or a memorial site at the rec where we used to watch Dom play basketball.
"Thanks again. We love you so much Dom," the victim's sister concluded.
