“Hell on Wheels” killer Mackenzie Shirilla’s has racked up 23 complaints while behind bars — including for flashing her breasts to visitors on video calls and stashing nude photos and mystery pills in her cell, according to records obtained by The Post.
Shirilla, 20, has amassed a staggering rap sheet at the Ohio Reformatory for Women since she was sentenced in August 2023 to two concurrent 15 years to life terms for the fiery 2022 car crash that killed her ex-boyfriend and friend.
The stunning documents expose a string of sexual offenses.
In one disturbing encounter in April 2025, Shirilla – who frequently customized prison-issued apparel, played with cosmetics and made jewelry, according to two former inmates – erupted after a prison official hit her with a dress code violation.
“If he got a boner from the way I’m dressed that’s his fault,” the convicted killer apparently bellowed as a female guard escorted her to a restroom, where she was ordered to ditch the form-fitting hoodie that had been “clearly taken in on the sides” and fix the prison-issued shirt she’d been wearing unbuttoned underneath, the document states.
“The whole time we were in the restroom she was very disrespectful and talked with a loud tone asking if this was all we were worried about was her altered jacket,” the female guard wrote in the conduct report.
The officer who issued the violation noted it was “at least the 3rd time” he’d seen Shirilla wearing contraband clothing and cited her with sexual harassment “for intentionally coming to another unit inappropriately dressed potential exposing herself to staff…[in] a, derogatory or offensive sexual nature,” according to the report. As punishment, she was sentenced to two weeks in restrictive housing away from the general population.
It wasn’t the only time Shirilla faced allegations of illicit sexual behavior behind bars.
A few months later, she landed in restrictive housing for a week after guards witnessed another inmate with “her hands in IP Shirillas [sic] pants in her buttocks region,” another conduct report states.
Though surveillance camera footage, the handsy inmate and other witnesses corroborated the incident, Shirilla pleaded not guilty to the sexual conduct citation.
“I did not allow her to touch me and I have never had a sex ticket and this is not me. I dont [sic] do that kind of stuff,” she said, according to the report.
On Aug. 22, 2025, Shirilla was busted again during a video visitation call when guards saw her “show her breast to the visitor,” a former ORW inmate, according to the report.
The unnamed visitor then returned the favor by showing “her breast with a dildo sticking out of her pants twice,” and walking into the camera frame completely nude, the reporting officer wrote.
Shirilla was slapped with 60 days of video visit restrictions, though she and the visitor had apparently completed at least six previous video calls before getting busted, the report states.
The records also show Shirilla repeatedly running afoul of contraband rules.
Nearly a year into her sentence, guards discovered a stash of prohibited items in her cell, including tie-dyed bras and Nikes, stolen arts and crafts supplies from a restricted area and two bottles of “mixed pills.”
In that case, her punishment was 60 days of restricted commissary and package privileges, the documents show.
And just over a month later, a random cell search turned up “4 nude magazine pictures,” two pairs of “altered state pants” and a fan in Shirilla’s dwelling – earning her another 30 days of commissary restriction, according to the conduct report, which did not elaborate on the nude photos.
More recently, guards found an unknown medication prescribed to someone other than Shirilla, along with a “personal photo of herself containing drug use” on Jan. 16 this year.
The inmate fired back in her response statement, saying the photo “did not have drug use in it” and bizarrely claiming the pills were “prenatal vitamins” she obtained from someone else, according to the report.
Shirilla’s other infractions have included playing with her tablet, “dancing” and hanging out in unauthorized areas and after lights out, blabbing through guards’ headcounts and logging 100 video calls with an unapproved visitor.
She has also been repeatedly cited for disobedience tied to her prison maintenance job, which records show she frequently neglects – or skips altogether.
Her punishments routinely include months-long restrictions on electronic, package, commissary and recreation privileges.
A judge found Shirilla – the subject of a new hit Netflix documentary “The Crash” – guilty of double murder during a dramatic bench trial in 2023. She is appealing her conviction for a second time.
