Two girls at a middle school in central Florida—aged 11 and 12—planned to kill 15 younger classmates with knives and then drink their blood, authorities said Wednesday. According to officials, the girls said they were Satan worshipers and were possibly going to eat the flesh of the children they murdered before killing themselves. The Bartow Middle School students were arrested Tuesday and charged with conspiracy to commit murder, possession of a weapon on school property, carrying a concealed weapon, and disruption of a school function. The plan was discovered when a robocall from the school to the home of one of the girls notified her parents their daughter was missing from class. The students were found in the bathroom with knives, a pizza cutter, and a goblet. A search of the girls’ cell phones found messages regarding the plot.
