The Parenting Challenge
Every parent knows the sinking feeling when your teenager comes home late, or you find something in their room that raises an eyebrow. We all have blind spots—the moments we choose to believe our child is just 'going through a phase' or that they'd never do anything truly dangerous. But what if that blind spot leads to tragedy? What if your teen's actions harm others, and the world turns to you, the parent, and asks, 'Why didn't you stop this?'
This is the raw nerve that the Netflix documentary on McKenzie Shirilla has touched. Shirilla, then 17, drove her car 100 miles an hour into a brick wall, killing her boyfriend and a friend. She survived. And now, a public outcry is demanding that her parents be criminally prosecuted. The question isn't just legal—it's deeply personal for every parent watching. How responsible are we for our teenagers' choices? Where is the line between a parent's ethical duty and criminal liability?
As a child development specialist, I've seen families grapple with this tension. We want to protect our children, but we also want to hold them accountable. When they hurt others, our instinct is to look for someone to blame—and sometimes, that someone is us. But the law, and developmental science, draw a different line than our emotions might.
What the Research Says
What the research actually shows is that adolescent brains are not fully developed, particularly in the prefrontal cortex, which governs impulse control, risk assessment, and long-term planning. This is why teens are more prone to reckless behavior—they literally process risk differently than adults. At 17, McKenzie Shirilla was at the peak of this developmental vulnerability. Her actions were not just a choice; they were a product of a brain still under construction.
But here's what most parenting advice gets wrong: it often assumes that parents can control their teens' every move. The reality is that by adolescence, peer influence often outweighs parental influence. Research by Dr. Laurence Steinberg at Temple University shows that teens are biologically wired to seek peer approval and take risks, especially in emotional or high-stakes situations. A parent's knowledge of their child's plans is often limited, and even the most vigilant parent can miss warning signs.
In the context of criminal liability, the law requires a direct connection between a parent's action and the child's harmful act. This is called 'foreseeability.' For a parent to be criminally responsible, the prosecution must prove that the parent knew—or should have known—that their child was likely to commit a violent act and did nothing to prevent it. This is a high bar. In the Oxford school shooting case, the parents were convicted because they bought their son a gun despite knowing he was in crisis. They had actual knowledge and contributed directly to the means of harm.
In McKenzie Shirilla's case, the 'weapon' was a car. She had a license. She was driving legally. There is no evidence her parents knew she planned to drive into a wall—indeed, she was planning to kill herself as well. As the legal analyst in the video points out, if her parents had known, they would have stopped her. This lack of foreseeability makes criminal prosecution difficult, even if the parents were ethically blind or in denial about their daughter's issues.
Practical Strategies
So, what can parents actually do to prevent such tragedies? First, let's talk about communication. It's not about interrogation—it's about creating a safe space for honesty. Here's exactly what to say when you sense something is off: 'I love you, and I'm not going to judge you. But I'm worried. Can we talk about what's going on?' This opens the door without accusation.
Second, monitor without hovering. For teens, knowing that you will check in—on their friends, their social media, their whereabouts—is a protective factor. But do it collaboratively. Say, 'I'm going to check your phone once a week. You can be there. Is there anything you want to tell me first?' This builds trust while maintaining boundaries.
Third, watch for clusters of warning signs: sudden changes in mood, withdrawal from family, new friends who seem controlling, risky behavior like substance use, and talk of hopelessness. If you see three or more, it's time to act. Call a therapist. Have a serious conversation. Don't wait for a crisis.
Finally, be aware of your own blind spots. We all want to believe our child is a good kid. But good kids can make terrible choices. Ask yourself: 'What would I do if I found out my child was planning something dangerous?' Have a plan. Know the resources in your community—crisis lines, school counselors, family therapists.
Real Parent Reality
Here's the honest truth: theory and real life don't always align. You can do everything 'right' and still your teen may struggle. I've worked with parents who were vigilant, communicative, and loving—and their child still ended up in trouble. Parenting is not a guarantee; it's a series of imperfect choices.
In the McKenzie Shirilla case, her parents appear to have had a massive blind spot. They saw their daughter as a 'good kid' who smoked a little pot, not as someone capable of murder-suicide. That's a painful reality many parents face: we don't always see what's in front of us. And when tragedy strikes, the guilt can be overwhelming.
But here's what I want you to hear: blaming yourself or being blamed by others doesn't undo the harm. What helps is learning, adapting, and doing better. If you find yourself in a similar situation—where your teen is in trouble—seek help immediately. Don't try to handle it alone. Call a professional, involve the school, and be transparent. The worst thing you can do is hide or minimize.
Different Ages, Different Approaches
For younger children (ages 5-10), the focus is on building a foundation of trust and open communication. Teach them that they can tell you anything without fear of punishment. Role-play scenarios: 'What would you do if a friend asked you to do something dangerous?' This builds decision-making skills early.
For pre-teens (ages 11-13), start the conversations about peer pressure and risky behavior. This is the time to talk about drugs, alcohol, and safe driving—before they're in the thick of it. Use media as a springboard: 'That movie character made a bad choice. What would you have done?'
For teens (14-18), the approach shifts to collaboration. They need more autonomy, but also more accountability. Set clear boundaries: curfew, check-ins, no unsupervised parties. And enforce consequences consistently. But also listen. Your teen is navigating a complex social world. Be their ally, not their adversary.
The Takeaway
The core principle to remember is this: you cannot control your child's every choice, but you can influence their environment and their trust in you. The legal system holds parents accountable only when they have direct knowledge and contribution. Ethically, our job is to stay engaged, stay curious, and stay humble about what we don't know.
One thing you can try today: sit down with your teen and ask one open-ended question: 'What's one thing you wish I understood better about your life right now?' Then listen. No judgment. Just listen. That connection might be the most powerful prevention tool you have.
