The prosecution called Mackenzie Shirilla cold and calculated. A judge called her "hell on wheels." The public split into two camps after Netflix's The Crash — she's a monster or she's innocent. But a psychotherapist who has spent three decades inside the minds of people who harm others sees a clinical picture that's messier than either side wants it to be.
Shavaun Scott is a licensed psychotherapist, author of The Minds of Mass Killers, and has worked in domestic violence shelters, forensic settings, and crisis teams. She examines what's operating underneath Mackenzie Shirilla's personality — the narcissism that presents as confidence but clinically almost never is, the self-obsession that masks profound fragility, and the fundamental question the trial never addressed: whether a seventeen-year-old's volatile behavior represents a fixed personality disorder or an adolescent brain that hasn't finished developing. The texts were ugly. The threats were real. But what they reveal about Mackenzie's inner world clinically is very different from what the prosecution used them to establish at trial.
Scott's analysis sits alongside a post-conviction strategic breakdown that raises equally uncomfortable questions. Shirilla agreed to appear in the Netflix documentary from prison. She was soft-spoken and remorseful on camera. Within days, a fellow inmate described a completely different person behind bars. The internet turned on her harder than before. Her pre-crash social media is still circulating — screenshots used to define who she is. The families are more vocal than ever. Dominic's sister has a podcast. The parents appeared in the documentary.
Criminal defense attorney Bob Motta advises clients on post-conviction strategy. He examines every decision Mackenzie has made since the verdict — the documentary, the public persona, the persistent "I don't remember" — and asks whether any of it helps at a parole hearing or whether she's actively burying herself deeper. Her appeals are exhausted. Her first parole date isn't until 2037. The question isn't whether she's guilty anymore. It's whether she understands what she needs to do next — and whether anyone around her is giving her that guidance.
