Mackenzie Shirilla Called Out by Victim’s Sister for 'Princess' Behavior Behind Bars

Dominic Russo’s oldest sister is calling out Mackenzie Shirilla for the way she is behaving in prison.

Shirilla’s case gained attention after Netflix released The Crash, which is a true crime documentary about a car crash she was responsible for that killed two of her classmates. And with that, it has led to increased attention for Shirilla.

“She’s just on her high horse in prison,”Christine Russo told PEOPLE. “She’s in prison and is very much acting like a princess and like she’s famous.”

“Becoming famous is all Mackenzie has cared about for a very long time,” she added. “After she killed my brother and Davion, within hours she was making TikToks of herself and trying to get modeling gigs.”

Christine’s brother, Dominic, was dating Shirilla and was one of the two victims, along with their friend, Davion Flanagan, who passed away after Shirilla drove her car into a brick wall, going nearly 100 mph. Following the accident, Shirilla was convicted of double murder and was sentenced to two concurrent terms of 15 years to life with eligibility for parole in 2037.

Christine said that Shirilla has “shown no remorse. She is a typical narcissist.”

This is not the first time Shirilla has been accused of acting different inside the prison, with Mary Katherine Crowder, a former inmate who served time at the Ohio Reformatory for Women, saying that he “jaw literally dropped” when she saw the Netflix documentary.

“Her demeanor and the way that she looked was nothing like the person I was in there with,” Crowder explained, going on to call her the  “Regina George of prison.”

When I was in there with her, you’d look at her and she had her makeup done every day, she was very well put together — almost like preppy,” she added. “This character in the documentary is nothing like who I saw in there at all, and it was shocking.”
