Mackenzie Shirilla, a convicted killer serving time in an Ohio prison, has reportedly earned a chilling nickname that reflects her notoriety behind bars. Her alleged ex-girlfriend, Shyann Topping, recently opened up about their brief romance and the unexpected dynamics of prison life in a series of revealing TikTok videos.
Topping claims that she and Shirilla began their relationship just weeks before her own release from prison. Initially, she was hesitant to approach Shirilla, describing her as exuding a “mean girl” vibe reminiscent of a character straight out of a teen movie. “Honestly, it felt like the Plastics were walking the track, prison style,” Topping remarked in her posts from August 2025.
However, their paths crossed through a mutual friend, and the two quickly formed a bond. Topping shared that despite the harsh realities of prison life, Shirilla was dedicated to her appearance, waking up as early as 5 a.m. to perfect her makeup and hair. “She always looked put together, like she was ready for a photoshoot,” Topping noted.
Interestingly, Shirilla reportedly avoided prison food, opting instead to cook meals using items from the commissary—a choice that Topping claimed could be quite costly. The two women resided in separate buildings on the prison grounds, with Shirilla living in a cottage described as more privileged, featuring flat-screen TVs and private rooms.
As their friendship blossomed, Topping faced her own challenges with rumors circulating about her charges. She clarified that she was not involved in any serious crimes, and during this time, Shirilla reportedly laughed off her own nickname, “Shirilla the Killa,” which had become a common reference among inmates.
Shirilla is serving a sentence of 15 years to life for a tragic car crash that resulted in the deaths of her boyfriend, Dominic Russo, and their friend, Davion Flanagan. Prosecutors allege that she drove at high speeds into a brick wall without applying the brakes. While Shirilla maintains that she has no memory of the incident, Topping recalled that she often spoke about the victims with affection.
Despite her conviction, Shirilla expressed optimism about her appeal, believing she would eventually be exonerated. Topping, who initially felt sympathy for Shirilla, later reassessed her views after researching the case post-release. “I realized that maybe she was just showing me what I wanted to see,” she reflected.
As of now, Shirilla’s appeal was denied by the Ohio Eighth District Court of Appeals due to a missed deadline, and she won’t be eligible for parole until 2037. What does this mean for the future of Mackenzie Shirilla, and how will her story continue to unfold?
