The Ohio school shooter Thomas "TJ" Lane smiled and laughed at the family members of his murder victims when he was sentenced Tuesday. 

Lane, 18, was sentenced to three life terms in prison with no parole.

Before the sentencing, ABC News reported that family members of the victims were allowed to share their thoughts with Lane, who killed three students "randomly" on Feb. 27, 2012 at Chardon High School before being chased out the school by a teacher.

When TJ Lane arrived for his sentencing hearing, ABC News reported that he unzipped his jacket to show he was wearing a white tee shirt with "KILLER" spelled out in large letters. He reportedly flipped off the entire courtroom when he was asked to give a statement.

He then said, "Fuck you all."

"Frankly, I wasn't prepared for this," the prosecutor said moments after Lane's gesture. He said the action was proof that Lane is a "disgusting human being." "This is confirming what we have known all along, that this was a cold, calculated, premeditated killing," the prosecutor said.

Daniel Parmertor, 16, Demetrius Hewlin, 16, and Russell King Jr., 17, died in the attack. Three other students were injured.

"A few weeks prior to the shooting, Russell told his friends that he wanted to hang out with the shooter again," Russell King Jr.'s sister told the court. "He wanted to be his friend. He felt sorry for him."

Lane reportedly smirked while King's sister spoke.

"I want him to feel my anger towards him," Dina Parmertor, Daniel Parmertor's mother said in the courtoom ."After today I refuse to give him a second of my thoughts...He is repulsive. We don't speak his name and we never will."

Lane reportedly laughed as she spoke.

"I am in pain every minute of every day. I cry every day,". "I will never be the same because of him...My children look at me and do not see the same mom they used to know."

As she called him a "monster" and "pathetic excuse for a human being," she would add, "I hope you have a cold, rough, unkind prison life with monsters like yourself," she said. "If I had my choice you would die an extremely slow, torturous death...You're a weak, pathetic, vile coward."

Judge David Fuhry said Lane appeared to simply want to "make a big splash, make front page news."

"[He] attacked without discernible motive, provocation or reason. The court finds such a person extremely dangerous," Fuhry said.

The town and school mourned over the past year, grieving over the actions of TJ Lane. Fuhry explained what kind of person Lane was before the Ohio high school shooting.

"To the contrary, TJ Lane was an intelligent student positioned to graduate early. He was not insane, incompetent or impaired on Feb. 27, 2012," the judge said. "He consciously and methodically carried out a plan to kill...Of course he knew that what he was doing was wrong."

Lane plead guilty on Feb. 26 to three counts of aggravated murder, two counts of attempted aggravated murder and one count of felonious assault. He was not eligible for the death penalty because he was 17 at the time of the shooting.
