Ohio School Shooter TJ Lane Jailed For Life

Ohio teenager TJ Lane, who admitted killing three students in a high school cafeteria in February 2012, has been sentenced to life in prison without parole.

The 18-year-old chuckled as the term was imposed for the deadly shootings at Chardon High School, 30 miles east of Cleveland.

After Lane arrived in court, he calmly unbuttoned his blue dress shirt to reveal the T-shirt reading "killer", which the prosecutor noted was similar to one he wore during the shooting.

At one point, Lane swivelled around in his chair toward the gallery where his own family and those of the slain teenagers were sitting and spoke only one sentence.

He made an obscene remark, then cursed at and stuck his middle finger up toward the victims' relatives.

The prosecutor said it just went to prove how much the killer is a "disgusting human being".

A student who was wounded in the shooting rampage dismissed Lane's outburst.

"He said it like a scared little boy and couldn't talk slow enough that anyone could understand him," said Nate Mueller, who was nicked in the ear in the shooting.

Dina Parmertor, mother of victim Daniel Parmertor, 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.

She said: "From now on, he will only be a killer. I want him to feel my anger toward him."

Prosecutors say Lane took a .22-caliber pistol and a knife to 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 had pleaded guilty in February this year to three counts of aggravated murder, among other charges, in a deal with prosecutors.

He was not eligible for the death penalty because he was 17 at the time of the shootings.
