The disturbing allegations have reignited public outrage surrounding the already controversial case, especially as Netflix’s documentary The Crash continues drawing renewed attention to Shirilla’s conviction and her insistence that the fatal collision was accidental.

Now 21 years old, Shirilla is serving two concurrent prison sentences of 15 years to life after prosecutors successfully argued that she intentionally drove her Toyota Camry into a brick wall at nearly 100 miles per hour in Strongsville, Ohio. Russo, 21, and Flanagan, 19, died in the crash, while Shirilla survived with serious injuries.

Although her appeals have failed so far, she remains eligible for parole in 2037 and reportedly continues fighting for a new trial.

The latest allegations come from Shyann Topping, a 27-year-old former inmate who claims she briefly dated Shirilla while both women were incarcerated at the Ohio Reformatory for Women in Marysville. According to Topping, the relationship lasted only about two weeks before her own release from prison, but during that short time, Shirilla allegedly revealed startling ambitions for her future.

“She said she was going to live it up when she gets out,” Topping claimed. “Concerts, traveling, becoming famous online — she talked about it constantly.”

According to Topping, Shirilla frequently discussed plans to write a book about her story and use the public attention surrounding the case to build a career as a social media influencer.

“She wanted to turn everything that happened into fame,” Topping alleged. “She believed people would follow her and support her.”

At the time, Topping says she initially sympathized with Shirilla because she believed the possibility that the crash may truly have been accidental. Shirilla has consistently maintained that she suffered a blackout caused by postural orthostatic tachycardia syndrome, commonly known as POTS, and claims she has no memory of crashing the car.

But after learning more details about the case and later watching The Crash documentary, Topping says her opinion changed dramatically.

“Now I think she just wanted attention,” she claimed. “I don’t think she cared the way people thought she did.”

According to Topping, Shirilla sometimes behaved as though she expected eventual freedom and future celebrity status rather than a lifetime defined by tragedy and prison.

“She really believed she would get out someday and become this big influencer,” Topping said. “Like everything would somehow turn into an opportunity.”

The allegations become even more unsettling given the emotional devastation still experienced by the victims’ families.

Dominic Russo and Davion Flanagan’s loved ones have spent years mourning the loss of two young men whose futures ended violently in the crash. Family members previously described Russo as loyal, loving, and deeply committed to those around him, while Flanagan was remembered as outgoing, energetic, and kindhearted.

For some observers, the idea that Shirilla may have discussed future fame connected to the case feels deeply disturbing.

“This wasn’t some internet scandal,” one online commenter wrote after Topping’s interview surfaced. “Two people died.”

Topping also claimed Shirilla occasionally embraced the notoriety surrounding her case while incarcerated. According to her, other inmates referred to Mackenzie using the nickname “Shirilla the Killa,” a label Topping says Shirilla did not strongly reject.

“She liked attention,” Topping alleged. “Whether it was positive or negative, she liked people talking about her.”

The former inmate described Shirilla as charismatic and socially confident inside prison, saying she had what she called a “popular girl aura.” However, Topping also compared her behavior to Regina George from Mean Girls, accusing her of being manipulative, demanding, and emotionally immature.

“She could be really sweet one minute and then act like a diva the next,” Topping claimed.

According to her account, Shirilla became upset over small things during their brief relationship, especially if Topping failed to meet her outside at scheduled recreation times.

“She’d get mad if I didn’t come outside exactly when she wanted,” Topping said. “She’d say stuff like, ‘If this is how it’s going to be, maybe we shouldn’t talk anymore.’”

Despite dating for only a short time, Topping claimed Shirilla quickly became emotionally attached and often talked about life outside prison walls.

“She told me she loved me,” Topping said. “And she kept talking about the future.”

According to Topping, Shirilla imagined eventually returning to concerts, traveling, and social media content creation after release. She also allegedly discussed writing about her experiences in prison and the crash itself.

Before her conviction, Shirilla reportedly maintained active Instagram and TikTok accounts where she posted videos dancing, posing for selfies, and sharing aspects of her personal life. Some older videos also showed her smoking marijuana while inside a vehicle, though experts later testified that marijuana was not considered a direct contributing factor in the fatal crash.

Topping claimed Shirilla remained heavily focused on her appearance while incarcerated. According to her, Mackenzie woke up early each morning to do her makeup and hair and cared deeply about how other inmates perceived her.

“She always wanted to look good,” Topping said. “Image mattered a lot to her.”

The former inmate also described daily life inside the Ohio Reformatory for Women, saying inmates had access to tablets, music, recreational activities, and jobs throughout the facility. Shirilla reportedly worked on a maintenance team that collected recycling between prison cottages.

Topping said Shirilla enjoyed art projects, painting cups and shoes for other inmates, and frequently attended weekly line dancing sessions in the prison gym.

“She was always smiling and busy,” Topping claimed. “Honestly, I never really saw her depressed.”

Those descriptions sharply contrast with the emotional image presented in Netflix’s The Crash, where Shirilla appeared remorseful and traumatized while discussing the deaths of Russo and Flanagan.

That contrast has fueled growing debate online about whether the documentary accurately portrayed her personality and emotional state.

Critics of Shirilla point to her alleged comments about fame and influencer culture as evidence that she remains more focused on herself than the victims. Supporters, however, caution against relying too heavily on prison gossip and secondhand claims from former inmates.

Still, Topping insists her perspective changed after studying the details of the case more carefully.

“She keeps pushing this POTS theory, but she never once showed symptoms around me,” Topping alleged. “No seizures, nothing.”

According to Topping, she eventually stopped communicating with Shirilla after demanding answers about the crash and becoming uncomfortable with her attitude toward the deaths.

“She needs accountability,” Topping said. “You can still love someone and admit what they did was wrong.”

The former inmate also criticized Shirilla’s family for continuing to defend her publicly, though she acknowledged the emotional difficulty parents face when confronting the reality of their child’s crimes.

“I understand loving your daughter,” she explained. “But at some point, there has to be honesty too.”

As the controversy surrounding The Crash continues growing, the allegations from Shirilla’s former prison girlfriend have added another troubling layer to one of Ohio’s most emotionally divisive criminal cases.

Whether Topping’s claims fully reflect reality remains impossible to independently verify. However, the accusations have intensified public fascination with Shirilla’s mindset, particularly regarding the role social media, attention, and image may have played both before and after the fatal crash.

Meanwhile, Mackenzie Shirilla remains incarcerated, serving her sentence while the debate surrounding her motives, remorse, and future ambitions continues far beyond the prison walls.
