Seven-year-old Katie Rough was killed after being stabbed at the neck and chest in a field
The death of Katie Rough shocked the country after the little girl was brutally slashed across the neck and chest in a field near to her home in Woodthorpe, York, in January this year.
Even more shocking was the fact that a 15-year-old girl was taken into custody.
The girl, who cannot be named, is now 16, and appeared at Leeds Crown Court earlier today via video link.
The teenager denied killing the girl in her earlier appearance in court on 13 January, but has today pleaded guilty to manslaughter by diminished responsibility.
She denied a separate charge of murder for killing little Katie, whose family appeared in court to hear the plea.
She appeared on the video link next to her solicitor, who confirmed her name, and wrote her guilty plea to manslaughter on a piece of paper.

Her solicitor told the court: "I can confirm she has indicated not guilty to murder but guilty to manslaughter."
Graham Reeds QC, prosecuting, said: "We are going to accept that plea of manslaughter by diminished responsibility."
Mr Reeds told the court that the girl had been through four psychriatric and psychological assessments, and there was "no dispute" that she was suffering from diminshed responsibility, despite planning the killing.
He also said that a member of the public had come across her wandering around, and she had immediately confessed to him that the little girl was dead and also where her body was.
Although Katie had suffered from two "severe" cuts to her body, one on her neck and one on her chest, she was actually killed from being smothered.
The teenager used a Stanley knife that she had taken from her grandmother's kitchen.
