A 17-year-old suspected of a deadly school shooting in the US state of Ohio has been charged as a juvenile, and faces three aggravated murder counts.TJ Lane allegedly killed three fellow students and wounded two after he opened fire in the cafeteria of Chardon High School.Trying Mr Lane as a juvenile would significantly reduce the amount of jail time he would face if convicted.However, the county prosecutor has said he plans to try him on adult charges.Juveniles convicted in Ohio generally do not stay in custody past the age of 21. However, a similar adult charge could see Mr Lane face life in prison. Mr Lane was also charged with two counts of attempted aggravated murder and one count of assault.Prosecutor David Joyce says the victims were random and has described TJ Lane as "not well”.‘Health nut’ The mother of Daniel Hewlin, one of the three students who died in the shooting, told ABC News she had forgiven the shooter.I only wish I could have done more. I’m not a hero”Frank Hall Chardon High School Football Coach "I would tell him I forgive him because, a lot of times, they don’t know what they’re doing. That’s all I’d say,” Phyllis Ferguson said.
