Davion Flanagan received eerie warning about Mackenzie Shirilla from dad Scott before she killed him in crash

Davion Flanagan's father, Scott, had a bad feeling about high school graduate Mackenzie Shirilla long before she killed him by purposefully driving her car into a wall at 100mph.

In fact, in the years prior to the fatal collision - which also killed Mackenzie's boyfriend, Dominic Russo - Scott had issued his son a word of warning about his choice of friendship group. During an appearance in the latest Netflix true-crime documentary, The Crash, the heartbroken father recounted his advice.

Davion had been just 19 when, on 31 July 2022, he'd made the fatal decision to accept a ride home from Mackenzie. Along with Dominic, 20, the pair of Ohio high school graduates had attended a party hosted by another of their close friends.

In the early hours of the morning, Mackenzie, 17, pummelled her 2018 Toyota Camry into the brick wall of a building, splitting the vehicle in two and instantly killing both Dominic and Davion.

Having survived, Mackenzie was airlifted from the scene and underwent a number of surgeries.

During police interviews, she claimed she'd blacked out ahead of the fatal collision, something she insisted was a regular side effect of her Postural Orthostatic Tachycardia Syndrome (POTS) diagnosis.

Despite this, Davion's father, Scott, had reason to believe she'd acted with a much more sinister intent.

Scott recalled his son began spending more time with Mackenzie, Dominic and the rest of the group after serious leg injuries prevented him from pursuing his college football dreams, and that they'd 'experiment with illegal drugs' together.

He then referenced the idea behind the phrase 'show me your friends, and I’ll show you your future', while discussing the social circle Davion had formed, specifically with regards to controversial character, Mackenzie.

"He'd come home late, and I'd say, 'Show me your friends, and I'll show you your future, Davion'," Scott added. "'Please stop'."

Also in the documentary, he slammed Mackenzie for treating Davion 'with the utmost disregard' in the months following the collision, citing her responding to modelling agencies' collaboration requests on Instagram just days after.

Branding Mackenzie's online antics as 'tone deaf', Scott hit out: "She just doesn't get how much anguish she's caused.

"No one in their right mind would post about being thrilled about this opportunity after they'd just killed two people in a horrific accident. It just felt off."

In a TikTok shared weeks after, she also was seen dressing as a corpse for Halloween, and in another, she lip-synced the lyrics, 'I'm the girl you die for', from the Marina and the Diamonds song, 'Bubblegum B***h'.

After Davion and Dominic's families raised concerns over these chilling social media uploads with the police, a more detailed picture of Mackenzie's personality began to take shape.

Investigators who assessed footage of the crash saw that Mackenzie appeared to drive the car directly towards the Plidco Building without attempting to slow down, and that the path the vehicle had travelled remained straight and controlled until the moment it hit the wall.

A forensic mechanical expert also confirmed that the vehicle's pedal had been pushed down to 100 per cent capacity for several seconds leading up to the crash, and that the brake hadn't been applied at all.

After police gathered enough evidence to prove that Mackenzie had purposefully crashed her car that night, she was arrested and charged with 12 charges.

These were four murder charges, four felonious assault charges, two aggravated vehicular homicide charges, one drug possession charge and one possession of criminal tools charge.

She was sentenced to two concurrent 15-to-life prison terms, with the possibility of parole in 15 years, after Judge Nancy Margaret Russo branded her 'hell on wheels'.

Reflecting on the case, Scott concluded in the documentary: "I have the capacity for forgiveness. I just want to know the truth of what happened that night, and I would be eternally grateful for her to actually tell us how those last few moments were - no matter how damaging to her they might be - to say just to say the truth and let us know and let us grieve properly and have some closure."
