Judge David Fuhry sentenced TJ Lane to life in prison without parole on each of three aggravated murder charges.

Twitter instantly lit up with posts expressing disbelief and shock at the defendant's callous behavior, with many commenters calling Lane 'sickening' and 'not human.' When Lane addressed the court, he flipped the middle finger and used profane language toward those in the audience, including the victims' families. This hand that pulled the trigger that killed your sons now masturbates to the memory. F*** all of you,' the gunman said, causing those in the audience to gasp in shock. '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,' and that the rampage was a 'cold, calculated, premeditated killing,' ABC News reported. Prosecutor James Flaiz went on to say: 'He still refuses to offer any explanation for why he did this. The only explanation I can offer the court is he is an evil person.

Lane wasn't subject to the death penalty because he was 17 at the time of the crimes. On Tuesday, Lane turned out in court wearing a white T-shirt with the word 'Killer' written on the front - the same word police say the 18-year-old had scrawled on his shirt the day of the deadly shootings. Lane has never offered a motive for the massacre.

It was a despicable, premeditated act. He should breathe his last breath in prison. Judge David L. Fuhry described the shootings as a 'merciless rampage,' noting Lane's apparent lack of remorse as part of his reasoning for the sentence, CBS21 reported. 'It appears to the court that the defendant simply wished to make a name for himself, to make a big splash, to make front-page news,' the judge said. The station WAFF reported that after being collared by police following the rampage, Lane was recorded in a squad car saying: 'I shot people.' When asked by an officer why he did it, the teen replied: 'I don't know.'

Defense attorney Ian Friedman said Lane plans to file an appeal, and has asked the court to appoint him a lawyer for that process. 'The defense is deeply sorry for the families, all of the families" pain, all of the families that have been affected by this,' Friedman said. 'There's nothing we can say that's going to lessen that.' No compassion: Judge David L.
