Two Florida teens have been arrested for plotting a classmate's murder at Lake Brantley High School.

Isabelle Valdez, 15 (who goes by Jimmy), and Lois Lippert, 14, were charged as adults with attempted first-degree premeditated murder after an anonymous tip exposed their plan. Obsessed with Sandy Hook shooter Adam Lanza, the girls allegedly aimed to perform a "blood ritual" to "resurrect" him, choosing a victim who resembled Lanza.

Valdez brought a sharpened knife to school, and post-arrest recordings show them laughing about the plot in a patrol car.
