Did postural orthostatic tachycardia syndrome (POTS) play a role in the tragic car crash that claimed the lives of Dominic Russo and DaVon Flanigan? This question has sparked intense debate as the case of McKenzie Shirilla continues to capture national attention.
On July 31, 2022, Shirilla drove at speeds between 90 and 100 miles per hour before crashing into a wall, resulting in the deaths of her boyfriend and his friend. Following a trial that concluded in 2023, she was found guilty of multiple charges, including murder and aggravated vehicular homicide, and was sentenced to life in prison with the possibility of parole starting in 2037.
Despite the conviction, Shirilla has maintained that she does not remember the events leading up to the crash. Her defense has pointed to POTS, a condition that can cause dizziness and fainting, suggesting it may have contributed to the accident. However, during the trial, no formal medical diagnosis was presented, and no medical expert testified on her behalf.
As the case gained traction on social media and in mainstream news, a Netflix documentary titled “The Crash” further fueled public interest. In it, Shirilla claimed she is not a monster and insisted that there was no intent behind her actions. She speculated that a medical emergency could have caused the crash, but when pressed on how she could maintain control of the vehicle during such an episode, she admitted, “I have no recollection of that morning.”
In the lead-up to the crash, text messages between Shirilla and her boyfriend revealed ongoing discussions about her health. While there were no explicit mentions of POTS, Shirilla expressed concerns about blackouts and severe pain, which her boyfriend attributed to issues with blood flow. These conversations raise questions about the severity of her condition leading up to the accident.

Court documents reveal that Shirilla’s mother testified she was diagnosed with POTS in 2017, but there were inconsistencies regarding how this condition affected her daily life. Notably, despite her diagnosis, Shirilla reportedly did not disclose her medical condition when applying for a driver’s license.
The appellate court reviewed the evidence presented during the trial, including testimonies from medical professionals who examined Shirilla shortly after the crash. They found no immediate signs of a medical emergency that would explain her behavior at the time of the incident. The court noted that while it is possible for someone to experience a medical episode, the evidence did not support this as a reasonable explanation for the crash.
Forensic psychiatrist Dr. Daniel Bober weighed in on the situation, explaining that while POTS can cause symptoms like dizziness, fainting is uncommon, especially while seated. He emphasized that if Shirilla had truly lost consciousness, she would not have been able to manipulate the vehicle in the way that she did.
As discussions continue around the implications of POTS in this case, many are left wondering: Could a deeper understanding of Shirilla’s health have changed the outcome of her trial? The complexities of her condition and the events leading up to that fateful day remain a source of intrigue and debate.
