Student Will Cornick has been given a life sentence after admitting to stabbing his teacher Mrs. Maguire in the neck and back, according to BBC News.
The 16-year-old boy reportedly showed a "chilling lack of remorse," and had said "good times" to his entire class, who witnessed him stabbing their teacher, when he returned from chasing the 61-year-old Spanish teacher from a room at Corpus Christi Catholic College.
Before the student killed his teacher, Cornick had reportedly expressed to his pupils that he hated Mrs. Maguire and wanted her dead.
"Late on the night of Christmas Eve 2013, and into the early hours of Christmas Day, the defendant exchanged messages with a friend on Facebook," stated the prosector.
The prosector continued, "In those messages he spoke of 'brutally killing' Mrs. Maguire and spending the rest of his life so as not to have to worry about life or money."
The teacher was 5 feet 2 inches tall and of slim build while the teenager was "a full foot taller and was armed with a large kitchen knife," according to the news outlet AFP.
"To describe his attack as cowardly hardly does it justice," stated prosector Paul Greaney QC.
The high school student reportedly told a psychiatrist that he knew the impact his actions would have on his teacher's family.
"I know the victim's family will be upset but I don't care. In my eyes, everything I've done is fine and dandy. It's kill or be killed. I did not have a choice. It was kill her or suicide," Cornick told the expert.
Will Cormick reportedly comes from a home with "responsible parents," who are "at a loss to understand how and why their son has turned out as he has."
Cornick had reportedly planned his attack before murdering the mother-of-two who had been teaching at the school for more than 40 years.
"I decided on Sunday it was going to be a knife. I thought I was just going to go to school and wait for her lesson and do it," Greaney, who was reading the boy's comments to the psychiatrist, stated.
He continued, "I wanted to get caught. That's why I did it in school."
