Isabelle Valdez, 15, and Lois Lippert, 14, are accused of plotting to murder a classmate at Lake Brantley High School in Seminole County, Florida. The teens were arrested in January and have been charged with attempted murder. Police have been listening in to a recorded conversation between them, which has been used as evidence by prosecutors. The girls shared an obsession with the shooter of the 2012 Sandy Hook Elementary School massacre and planned to use the victim's blood in a ritual to "bring back to life" the shooter.
