Two New Jersey girls are in serious trouble after a 20-minute video surfaced online of them talking about several teachers and classmates they wanted to kill.

The 12-year old girls can be heard talking about being assassins and threatening several people after one of them read a note aloud at school that contained a “hit list” of sorts. Though they’re laughing most of the time in the video, it’s a haunting depiction of youth to the parents of those who were named.

“My daughter, she woke up about four times last night, to lock the doors. She woke up with nightmares,” said parent Angelica Marrero.

The video has been taken down off YouTube and the girls have been pulled from school as police perform an investigation, but they say they don’t believe there was ever any real threat to students or faculty. However, charges might be brought against them, and most parents believe that would be a good thing.
