Prosecutors say Lane took a .22-caliber pistol and a knife to the school last Feb. 27 and sprayed bullets at a group of students in the cafeteria.
According to investigators, Lane has admitted to the shooting and believed he had "killed a bunch of people," but doesn't know why he did it, WEWS reported.
Danny Parmertor, Russell King Jr. and Demetrius Hewlin died as a result of the shooting. Three more students, Nick Walczak, Nate Mueller and Joy Rickers, were injured.
Earlier this month, Mueller traveled to Washington, DC, as part of a group urging Congress to pass gun control legislation, Reuters reported.
