Her angelic face didn't save her from paying for her horrible crime

Mackenzie Shirilla kept crying in front of the judge.
She was only 19 years old and she had already become a criminal.
Her crime? She k*lled her boyfriend and his best friend by crashing her car into a building.
She tried to pass the incident off as an "accident" in which she was the only one who escaped unharmed.
And although at first her version was credible, the investigators discovered that the "sweet" girl had planned the crime many days in advance.
