Louisville, Ky. (WHAS11) - A Tennessee school district said it foiled two teenagers' plan to kill as many students and teachers as possible.
The sheriff said one of the boys came up with the plan and recruited another student to help carry it out.
Deputies searched their homes and found notes on how to carry out the attack, as well as several guns.
The boys mapped out where would be the best place to enter the school and cause the most damage.
A counselor found a journal detailing the plot and alerted police.
Investigators found videos of the suspects on the Internet, firing guns and setting off homemade explosives.
Both teens are now charged with conspiracy to commit first degree murder.
