Mackenzie Shirilla's 'prison girlfriend' reveals sick nickname killer had in jail
The woman who killed her boyfriend and his friend in a horror car crash by intentionally driving into a wall at 100mph has apparently earned herself a sickening nickname in prison.
Mackenzie Shirilla was just 17 when she committed the horrifying double murder that shocked the world and made her famous across the country.
Her case has been brought back into the spotlight in recent weeks with the airing of a new documentary about her deadly decision to stamp on the accelerator in the early hours of July 31, 2022.
This ultimately led to her being found guilty of multiple counts of murder and aggravated vehicular homicide, with her being handed 15 years to life in the Ohio Reformatory for Women, where her 'prison girlfriend' says she is earning a reputation.

Her former inmate and jailhouse lover at the Ohio women's prison - where Shirilla will remain until at least 2037 - has spoken to the US Sun about how the double-murderer is adapting to life behind bars.
And she seems to be taking a liking to her newfound infamy. Shyann Topping, 27, told the publication: “We started talking and she told me her nickname was ‘Shirilla the killa,’ like, that’s what her bunkmates called her.”
Topping said that she had even dated 'Shirilla the killa' for a couple of weeks while she was locked up with her, but chillingly added that the now-21-year-old is a particularly demanding person to be in a relationship with.
One of the sticking points in the romance for Shirilla was if her older lover was late to the prison yard, as that was where they could be 'intimate'. “If we did argue, it’s because I didn’t come outside on time,” Topping shared of her demanding behavior.
This would even escalate into threats if she didn't make it into the yard on time. Topping added: “And she’s like, ‘I was waiting for you. Where were you? Like, if this is how it’s gonna go, I just won’t talk to you.'”
But their trust came tumbling down just two weeks into their prison romance, after Topping was released from her sentence. This was said to devastate Shirilla, who had already told Topping that she loved her.
The ex-con added: “Mackenzie was upset that I was leaving. She would tell me all the time, ‘I wish we met sooner, before you were about to get out. I wish you would have talked before this.'"
Topping told the Sun that, even in that two-week whirlwind romance, Shirilla had spoken to her about her grand plans for when she eventually gets out of prison. “She said she was just gonna live it [up],” she told the publication.
Apparently, Shirilla is even plotting to rehabilitate her image. Topping said: “Like, she’s gonna go back to concerts. She’s gonna travel. She’s gonna be an influencer and write a book when she gets out about everything that happened.
“She said it might take some time, but she’s gonna get out and live it again.”
