More information has been released about the suspect in the Arapahoe High School shooting last Friday.
Investigators say the shooter planned to attack at least five areas of the high school that day.
Arapahoe County Sheriff Grayson Robinson released a statement with new details, saying the shooter was armed with a 12-gauge, pump-action shotgun; three functional Molotov cocktails, a machete in a canvas scabbard and more than 125 rounds of assorted types of shotgun ammunition (steel-shot, buckshot and slug). Investigators say Karl Pierson carried the ammunition in two bandoliers worn across his chest and waist and carried the remaining items in a backpack.
Pierson used a marker to write a phrase in Latin on the inside of his forearm. "Alea iacta est," which translates into English as "the die has been cast," as well as five separate letters and numbers on his arm, which investigators say correlate with the library and classrooms nearby.
Investigators will try to determine whether the shooter had targeted anyone in any of those classrooms.
The shooting critically injured 17-year-old Arapahoe High School senior Claire Davis. Pierson died as the result of a self-inflicted gunshot while inside the high school library.
Sheriff Robinson says it appears that Pierson acted alone, but investigators are still looking into whether anyone may have helped the him in any way.
