Dina Parmertor, mother of victim Daniel, called Lane "a pathetic excuse for a human being" and wished upon him "an extremely, slow torturous death." She said she has nightmares and her family has been physically sick over the crimes.
"From now on, he will only be a killer," she said, as Lane's smile widened. "I want him to feel my anger toward him."
Prosecutors say Lane took a .22-caliber pistol and a knife to the school and fired 10 shots at a group of students in the cafeteria. Daniel Parmertor and Demetrius Hewlin, both 16, and Russell King Jr., 17, were killed.
Lane was at Chardon waiting for a bus to the alternative school he attended, for students who haven't done well in traditional settings.
Six days before the rampage, Lane had sent a text message to his sister, who attended Chardon High school, and mentioned a school shooting, Geauga County Prosecutor James Flaiz disclosed after the sentencing. He gave no details about what the message said.
"The way the text message was phrased to his sister, I'm not sure she would have taken it as anything. I think only when you look at it in retrospect does it really have the impact that it does now," Flaiz said.
Lane's sister, Sadie, was in the cafeteria the day of the shooting and said outside the snow-swept courthouse that the brother she saw in court wasn't the one she remembers. She asked for prayers for her family.
"It may be hard for some to understand, but I love my brother and hope that whatever the sentencing in life takes him in the future, that he can touch others' lives in a positive way from the point of view that only he can give," she said.
