CHARDON, Ohio — A teenager charged with killing three students at an Ohio high school pleaded guilty to all charges Tuesday, the eve of the first anniversary of the shooting rampage.
T.J. Lane, 18, pleaded guilty to three counts of aggravated murder, two counts of attempted aggravated murder, and a single count of felonious assault.
The Wednesday anniversary of the attacks at Chardon High School comes after a year of mass shootings, including one that left dead 20 first-graders and six educators in Newtown, Conn., and another that claimed 12 lives at an Aurora, Colo., movie theater.
The anniversary in Chardon, a tight-knit community east of Cleveland, will be marked with a memorial walk and service activities.
Lane, dressed in a green open-collar shirt and dark slacks with his once-shaggy hair buzzed short, held his head up without emotion Tuesday as he repeatedly said, ‘‘Yes, your honor,’’ to questions posed to him by the judge.
He could face life in prison. Judge David Fuhry scheduled sentencing for March 19.
