The text messages Mackenzie Shirilla sent Dominic Russo were controlling, threatening, and ugly. The TikTok persona was image-obsessed. The arrest behavior was bizarre. Everything about her personality fed a narrative that she was cold enough to plan a murder at seventeen. A judge agreed. But a psychotherapist who has treated both victims and perpetrators of violence for over thirty years reads the same evidence and sees a completely different clinical picture.
Shirilla was convicted of four counts of murder for the Strongsville, Ohio crash that killed Dominic Russo and Davion Flanagan. Netflix's The Crash has reignited the debate over whether this was premeditated or something else entirely. But the psychological dimension — the question of what's actually happening inside someone who behaves the way Mackenzie did — barely gets examined.
Shavaun Scott, author of The Minds of Mass Killers, brings three decades of clinical experience to the personality profile that convicted Mackenzie Shirilla. The narcissism the public sees as proof of coldness? Clinically, it almost always signals the opposite — someone with no stable sense of self, terrified of abandonment, constructing an identity out of image because there's nothing solid underneath. The ultimatums and threats? Driven by desperation, not calculation. The volatility? Possibly personality disorder, possibly a teenage brain that hasn't finished developing. The distinction between those two things matters enormously — and the trial never explored it.
This conversation goes where the documentary and the courtroom didn't — inside the clinical reality of who Mackenzie Shirilla actually is, not who the prosecution needed her to be.
