T.J. Lane, who appeared in court the morning wearing a t-shirt with the word “KILLER” in marker across his chest, will spend the rest of his life in prison for the murder of three teenagers at an Ohio high school.

Going against the recommendation of his counsel, Lane addressed the courtroom before learning his fate. He smiled periodically and  showed little remorse for his actions.

“F—all of you, ” he said, before raising his middle finger at the victims’ families, according to the Plain Dealer.

On Feb. 27, 2012, Lane, then 17, entered Chardon High School, east of Cleveland and opened fire, killing Daniel Parmertor and Demetrius Hewlin, both 16, and Russell King Jr., 17. Three other students were wounded.

Nearly one year later, Lane pleaded guilty to three counts of aggravated murder, two counts of attempted aggravated murder and one count of felonious assault.

Lane received three life sentences without the possibility of parole. Because he was a juvenile at the time of the incident, Lane could not face the death penalty.

CHARDON, Ohio (AP) — Wearing a T-shirt with “killer” scrawled across it, a teenager cursed and gestured obscenely as he was given three life sentences Tuesday for shooting to death three students in an Ohio high school cafeteria.

T.J. Lane, 18, had pleaded guilty last month to shooting at students in February 2012 at Chardon High School, east of Cleveland. Investigators have said he admitted to the shooting but said he didn’t know why he did it.

Before the case went to adult court last year, a juvenile court judge ruled that Lane was mentally competent to stand trial despite evidence he suffers from hallucinations, psychosis and fantasies.

Lane was defiant during the sentencing, smiling and smirking throughout, including while four relatives of victims spoke.
