First responders arrived at the scene and found three people inside the vehicle — Shirilla, her boyfriend, Dominic Russo, and Davion Flanagan.
All three were unconscious and not breathing, officials said. Russo and Flanagan were pronounced dead at the scene but Shirilla survived.
While announcing her verdict, Russo said, “The video clearly shows the purpose and intent of the defendant. She chose a course of death and destruction that day.”
Shirilla was found guilty of murder, aggravated vehicular homicide and felonious assault. Russo said Shirilla had “a mission” and executed it “with precision.”
"She morphs from a responsible driver to literal hell on wheels as she makes her way down the street," Russo said. "Mackenzie alone made the decision to drive the car, to drive an obscure route, a route she visited a few days before, and a route not routinely taken by her. Mackenzie alone chose a time to make the drive, early in the morning, when any reasonable person would expect a few people would be nearby to witness it or offer life-saving assistance."

During the trial, prosecutors said Shirilla crashed the vehicle to end her toxic relationship with Russo, WKYC reported.
After the verdict, Shirilla’s mother told WKYC she was shocked by the murder conviction and completely disagrees with the judge and wants an appeal.
Shirilla is set to be sentenced on Aug. 21, officials said.
