1. Chardon High School
In the early hours of February 27th, a young man at Chardon High School near Cleveland, Ohio, walked into his cafeteria and began shooting. Firing into the crowd, his shots ended the lives of three, and seriously injured two. Witnesses quickly identified the shooter, who attempted to escape to his car following the incident as a schoolmate, 17-year-old T.J. Lane. On Dec. 31, 2011, Lane posted a rhyming rant on his Facebook profile, in which he describes “a man with a frown” who is consumed with resentment and ruminates about conducting a massacre. Lane, who turned 18 shortly after, was tried as an adult and convicted of three-counts of aggravated murder. Killed in the attacks were Demetrius Hewlin, 16, Russell King Jr., 17, and Daniel Parmertor, 16.
