A young boy has allegedly killed off his own schoolteacher inside their classroom in a really brutal attack.
The story has been told of the murder of Ann Maguire. Ann had been murdered by 15-year-old Will Cornick.
According to Daily Star UK, she had been his Spanish teacher and he told people that he hated her with a passion.
He stabbed her several times from behind as she helped a fellow student with their work. He then started to chase her as she tried to run for her life.
