A TEENAGER WHO planned a mass killing at his former college was jailed for life in Newcastle today, and will serve a minimum of eight years in prison.

The BBC reports that 19-year-old Liam Lyburd was convicted of possessing pipe bombs and a gun, amongst other weapons, with intent to endanger life.

Jurors were told the “cold and detached” Lyburd held a grudge against the Newcastle College after he was thrown off a course.

He had admitted possessing the bombs and a semi-automatic pistol.

The judge, Paul Sloan, said he was in no doubt the teenager would have carried out the planned attack if he hadn’t been caught.

“Your emotional coldness and detachment and your lack of empathy to others was self-evident,” Sky News reported the judge as saying.

“It was only a matter of time before you would have put your plan into action.”

A deleted file from the teenager’s computer revealed that he wrote: “People will die, there’s no question about that”.

The mass murder plot was uncovered by police last November after a member of the public reported disturbing Facebook posts by the teenager.

A bag of weapons was found in his room, according to TheGuardian, along with overalls, a mask, and boots.

A computer scientist found deleted files on his computer in which he talked about getting vengeance on his former college.

It also included the line:

“I’ll teach you people a little lesson on respect with my 9mm jacketed hollow points.”
