Katie Sharon Rough (16 January 2009 – 9 January 2017), a 7-year old English girl, died in the Woodthorpe area of her hometown of York in the United Kingdom, on 9 January 2017. She was killed by a girl aged 15 years old at the time, who handed herself in to the police immediately after attacking Rough. Under UK law, Rough's killer was considered a minor at the time of the killing, and so her name was not made publicly known in the subsequent investigation and trial. Rough's killer pleaded guilty to manslaughter on grounds of diminished responsibility. It emerged that the teenager had been suffering from psychosis at the time of the attack, caused by an unknown psychiatric disorder and she was subsequently sentenced to a minimum of five years' detention on 24 November 2017. Attack Katie Rough was last seen alive at 4:20 p.m. on 9 January, with a local resident subsequently reporting to have seen her and her eventual killer playing together in a playing field near Alness Drive, without any indications of the violent act which was to follow. Fifteen minutes later, at 4:35 p.m., the elder girl placed a 999 call and confessed to having killed Rough, though claimed not to remember any specific details of the event. The girl was then found by another local resident, Peter Mills, who subsequently found Rough's body a short distance away down a side street. Though attempts were subsequently made to resuscitate Rough, she was ultimately pronounced dead at York Hospital at 5:40 p.m., a little over an hour after the initial 999 report was made. An autopsy of Rough's body revealed that she had been fatally asphyxiated, with a green glove later being identified as the murder weapon. It was also found that wounds had been inflicted on her in the neck and chest areas with a Stanley knife, though it was determined that said wounds were not inflicted until after she was already dead. Aftermath Around the time that Rough was officially declared dead, the 15-year-old girl was arrested and formally charged with her murder. Subsequent investigations found that she suffered auditory hallucinations and delusions and often experienced violent fantasies, which she acted out by mutilating and defacing soft toys at her home. It was also found that she was convinced that most of the people around her were robots disguised as humans. In the previous
