A life sentence isn’t all she’s serving. 

“Hell on Wheels” killer Mackenzie Shirilla is reportedly dishing out prison chow at the Ohio penitentiary where she’ll be spending the rest of her life.

While little else was revealed about the 21-year-old murderer’s new job, inmate kitchen workers are typically tasked with preparing and serving meals to other prisoners. Prison officials at the Ohio Reformatory for Women confirmed Shirilla’s new post to Fox News Digital.

Shirilla likely had to undergo a medical exam to confirm she doesn’t have any contagious diseases before she was allowed to work around food, based on state guidelines. 

The flashy felon will also have to don a not-so-glamorous hair net while dishing out prison slop, according Ohio Department of Rehabilitation and Corrections regulations state. 

Ohio inmates can earn a measly $3 to $22 per month, depending on their hours – but Shirilla reportedly has a side hustle that keeps her commissary fund full. 

She allegedly has online sugar daddies who send her money for makeup and outfits when she’s strapped for cash, Mary Katherine Crowder, who served time with Shirilla at the Ohio prison, previously told The Post. 

And even if her rich online companions don’t come through, Crowder said her parents were always sending her money. 

Ex-friends of Shirilla – who is behind bars serving a life sentence for intentionally speeding into a building in 2022 and killing her boyfriend Dominic Russo, 20, and friend Davion Flanagan, 19 – have described her as self-absorbed and spoiled. 

Shirilla was a recent graduate of Strongsville High School when she committed the heinous crime, but relatives and others who have spoken out about her have never mentioned her holding down a job. 

Shirilla’s new gig comes just days after she told her mom she was bored behind bars because “there is nothing for me to do” in a leaked call obtained by TMZ.

Crowder said she remembered Shirilla as a status-obsessed inmate who wasted no time earning a “mean girl” reputation. 

“Everyone knew why she was there, and she walked around like she was this famous person within prison,” Crowder said. 

“She always had makeup done, hair done, her clothes were altered to fit her body tighter or be different.” 

Shirilla was sentenced to life in prison in August 2023, but the Netflix documentary “The Crash” re-sparked the frenzy surrounding the sinister case.

She will be eligible for parole in October 2037.
