Insufferable Teen Horrifies Her Town After Murdering Two Friends

This is Mackenzie Shirilla… who has become better known as one of America’s most insufferable young killers. You may have heard her name before… but do you really know the full story? In the aftermath of a horrifying tragedy, Mackenzie managed to fool millions. Countless people believed that she was simply the driver caught up in a terrible accident. However, those closest to her suspected there was far more beneath the surface… And they were right. Through some remarkable technical investigation, detectives uncovered that this was no accident at all. And as her phone data, social media activity, and private messages were seized, and later released to the public, the world began to see that behind her young sweet façade was something far darker. What emerged were deeply unsettling phone calls… hundreds of bizarre videos filmed behind the wheel… and literally thousands of pieces of evidence that revealed an erratic, selfish, and deeply controlling teenager. And that was only the beginning. Because what she posted after the deaths of her boyfriend and her best friend… Well, that is something that will stay with you long after this story ends.DISCLAIMER: Great effort is made to ensure all materials in Coffeehouse Crime's videos fall within the guidelines of fair use.
