"Cornick told a psychiatrist he killed Maguire because “life is pretty fucking shit” and that he had planned a triple homicide. He said he did not regret his actions and was pleased to have killed the teacher but “it didn’t live up to” his expectations.

He later said: “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.”

A paramedic with 30 years’ experience said Maguire’s wounds were the worst she had ever seen. All of them had been inflicted from behind.

At an earlier court hearing in July Cornick accepted responsibility for unlawfully killing Maguire but stopped short of admitting he had murdered her. Following this admission, the judge ordered a series of psychiatric assessments, which concluded that he was of sound mind when he was carrying out the attack. That conclusion meant he was deemed fit to stand trial for her murder."
