Newly resurfaced bodycam video shows the shock as cops found “Hell on Wheels” killer Mackenzie Shirilla still alive in her wrecked car alongside the bodies of her boyfriend and his pal, whom she murdered by deliberately crashing into a wall at nearly 100 mph.

“Holy smokes… the last thing you expect to see,” a responding officer gasped at finding the then-17-year-old driver still alive in her car that was split in two.

“This is the worst crash I’ve ever seen,” added the distraught cop after finding the murdered males.

Shirilla murdered her boyfriend, Dominic Russo, 20, and his friend Davion Flanagan, 19, by intentionally slamming her car into a wall in suburban Cleveland in July 2022 at nearly 100mph.

The grim, newly resurfaced footage of the horrified first responders rushing towards the scene resurfaced this week after the details of the dramatic case were laid bare in a new Netflix documentary.

“This is bad, guys,” one officer could be heard saying in the unsurfaced raw footage obtained by TMZ.

It was as the cops sprinted towards the vehicle that they realized Shirilla was still breathing.

“The driver is breathing, unconscious,” one shouted in emotionally charged scenes. “We’ve got two that are gone.”

The clip then shows officers frantically trying to break the driver’s side window to get to Shirilla.

When fire crews were eventually able to tear off the door and reach Shirilla, the teen could be heard screaming as they pulled her from the wreck and transferred her to an ambulance.

Shirilla, now 21, has been behind bars since she was convicted in 2023 of murder and a spate of other charges following a dramatic trial where the judge blasted her as “literal hell on wheels.”

The new Netflix documentary documenting her case — “The Crash” — quickly climbed to No. 1 on the streaming platform’s most popular list since it was released earlier this month. 

Shirilla appears in the documentary from behind bars — where she expresses remorse for the fatal crash and insists she’s “not a monster.”
