Two middle school girls are now in custody after being found in a bathroom allegedly plotting to murder some of their classmates, cut up their bodies, eat their flesh, and drink their blood for Satan, according to reports from NBC and BuzzFeed News.

Police said the girls were found with several knives and a pizza cutter on them, and admitted to planning to kill at least 15 of their peers and “leave body parts at the entrance" of the school. The girls, ages 11 and 12, were 6th and 7th grade students at Bartow Middle School in Bartow, Florida.

The pre-teens claimed to be practicing Satanism and said they "were willing to drink blood and possibly eat flesh." Per the arrest report, they explained their plan to wait for “smaller students” to overpower and kill. After murdering their classmates, the girls planned to leave body parts at the school's entrance and commit suicide.

“The plan was to kill at least one student but were hoping to kill anywhere from 15–25 students,” reads a warrant filed by the department. “Killing all of these students was in hopes it would make them worse sinners ensuring that after they killed themselves … [they] would go to hell so they could be with Satan.”

The girls were found after a student reported that one of the girls told them to stay away from a specific part of the school because "something bad was going to happen." The principal and teachers searched the school and discovered them in the bathroom with "a goblet or glass in their possession," Chief of Police Joe Hall said during a press conference on Wednesday.

The girls have now been charged with conspiracy to commit murder, possession of a weapon on school property, and disruption of school function. It’s unclear if they will be tried as juveniles or adults. 

“Today is sad,” Polk Schools Superintendent Jacqueline Byrd said at the news conference with Hall. “We have students who were plotting to kill other students.”
