One ex-inmate who served time with Mackenzie Shirilla, the subject of a new documentary, The Crash, revealed how the convicted criminal behaved while in prison.

Mary “Kat” Katherine Crowder, who goes by @boujeebehindbars on TikTok, took to the popular social media platform to speak on Shirilla, 21, in the wake of a new Netflix documentary. Shirilla was convicted on a handful of charges, including murder, after she killed her boyfriend, Dominic Russo, and friend, Davion Flanagan, when she crashed a car into a wall while driving over 100mph.

Crowder, 27, was an inmate in the Ohio Reformatory for Women alongside Shirilla, whom she described as only caring about “doing her makeup” and walking around the yard with her “one or two friends who were also very similar to her – young girls, social media influencer wannabes” Crowder’s comments come as audiences decried Shirilla’s apology in The Crash.

Crowder continued to describe Shirilla’s unfavorable behavior, saying that she “walked around prison thinking, ‘How is she going to get in with the cool kids?’” She quipped that Shirilla, who she deemed to be “thriving for fame,” thought that “she was gonna be the princess of the prison.” She described Shirilla as treating prison like a “high school popularity contest.”

Crowder added that Shirilla even changed her style of speaking for her appearance in The Crash, shifting away from her reportedly “raspy” natural voice.

Crowder exposed Shirilla for lying about having been high on psilocybin when the crash occurred.

“They showed in this documentary…There was only THC found [in her blood],” Crowder said.

“So, now, like, girl, I already knew that you were lying, but now it’s like you’re just making up a huge story with no evidence to even try to back you up,” she said, “So, you look even more guilty.”

“You don’t care that you took these lives,” Crowder emphasized. She added that she never saw Shirilla cry.

Crowder turned her attention to Shirilla’s “bats— crazy” mother, who was “funding her prison lifestyle.”

“Her bozo a– parents fed into this,” she said.

Crowder explained that Shirilla had “everything you could imagine inside prison and more,” including makeup products and other “limited items” paid for by her family via CashApp.

“Her family enables her like no other,” Crowder said, “They see no wrong. They’re delusional and Mackenzie has to get it from them.”

Crowder noted that Shirilla’s mother is eager to appear on “social media, on a podcast, on a documentary…because she could care less about those victims.”

She accused Shirilla of putting on an act for the cameras, and mused that her appeals will continue to be denied.
