Mackenzie Shirilla definitely did The Crash intentionally, no doubt in my mind.

The fact is she floored the gas pedal for 5+ seconds at 100mph on a residential road straight into a building. 100% gas, zero breaks, while steering perfectly down a non-straight road. That’s not possible if she had any kind of medical episode. She wasn’t distracted by her phone, or drunk at all. I’ve driven cars my whole life and I don’t think I’ve ever 100% floored the gas pedal. It was intentional.
The motive was that she was a narcissistic “mean girl” that thought she was better than everyone including her bf. He wanted to break up and she was crazy enough to burn it all down. She thought she was pretty enough to get away with anything because she’d never had any consequences or discipline in life.
She was smug enough to choose a bench trial rather than a jury trial which has to be one of the dumbest decisions a defendant can make.
A New Zealand study followed 1000 kids for 45 years and found out that the best predictor of health, wealth, and public safety was the level of childhood self-control taught by parents. Her doofus of a father allowed her to smoke weed daily as a teenager and bully girls at school with no repercussions. Her parents failed miserably and they are either too stupid to realize it or too cowardly to admit it, even after their daughter was convicted of double murder and lost her appeal.
Even Kim Kardashian was smart enough to want nothing to do with her case.
The irony is that she has to live 15+ years in prison while living her lie in hopes of convincing the parole board of that same lie that hasn’t worked yet, when instead if she just admitted it she would have gotten the same sentence, mental peace of mind, and could act remorseful of that one terrible impulsive teenage decision and almost certainly be paroled out before she’s 33yrs old.
