A Wirral teenager has admitted murdering his girlfriend in a brutal attack described to a court as "torture".
Hannah Windsor, 17, was tied to a tree, sexually assaulted, strangled and attacked with a knife by Adam Lewis, 18, Liverpool Crown Court heard today.
Lewis, of Fairmead Road, Moreton, had denied murdering Miss Windsor but changed his plea to guilty shortly before his trial was due to begin, and admitted two counts of sexual assault against his victim.
The partially clothed body of Miss Windsor, who was living at a hostel for homeless young people at the time of her death, was found hidden under leaves, twigs and dirt in woodland on Bidston Hill, Wirral, on May 19.
Neil Flewitt QC, prosecuting, described Miss Windsor's injuries as "highly distressing".
She was restrained and tied to a tree, sexually assaulted, stabbed repeatedly and suffered multiple other knife wounds to her chest, abdomen and back, he said.
Mr Flewitt added her mouth had been covered with surgical tape and she was strangled with a combination of his hands and a ligature, and there were severe wounds in her genital area and evidence of sexual assaults.
"The nature and extent of the injuries were such that the pathologist concluded Hannah had been the victim of torture," Mr Flewitt told the court.
Miss Windsor and Lewis, who were both diagnosed with Attention Deficit Hyperactivity Disorder (ADHD), had met when they were pupils at a Wirral special school.
After leaving school they had been in a relationship for seven months before splitting up and reuniting about six weeks before he killed her, the court heard.
