A 15-year-old boy was found guilty of murder on Thursday after he kicked a woman to death because she was a "Goth". Brendan Harris was found guilty at Preston Crown Court of killing Sophie Lancaster after she was attacked in a park in Burnley, Lancashire, last August. The 20-year-old gap year student had been with her boyfriend Robert Maltby when a group of youngsters set upon him in an unprovoked attack. She begged them to stop, but was kicked and punched too. The pair were left unconscious. Lancaster's injuries were described as so bad that it was difficult at first to tell what sex she was. The jury heard the couple were attacked because they were wearing "Goth" clothing. Followers of the "Goth" subculture, which began in Britain during the early 1980s in the gothic rock scene, stand out because of their black clothes and make-up. Maltby, 21, survived, but Lancaster died from serious head injuries two weeks after the incident. Harris pleaded guilty to causing grievous bodily harm with intent to Maltby, but had denied attacking Lancaster. Another youth, Ryan Herbert, 16, had earlier pleaded guilty to the murder of Lancaster and causing grievous bodily harm to Maltby. A judge lifted a ban on identification of the two. Three other males, two aged 17 and one 16, who still cannot be named, also admitted causing grievous bodily harm with intent to Maltby. Murder charges against the three were withdrawn. Lancaster's mother, Sylvia, said after the case that she had received thousands of messages of support from around the world. "Sophie was a thoughtful, sensitive individual and she would not have wanted her death to have been in vain. "I hope, therefore, that as a society we can use what has happened to reflect on where we are going and what changes we need to make to prevent others suffering in this way." Senior Investigating Officer Detective Inspector Dean Holden from Lancashire Constabulary, said: "This was a tragic and senseless killing of a young woman and a vicious and unprovoked attack on a young man in a quiet town. "To my mind, this stands as a fine example of how anti-social behaviour mixed with alcohol abuse can accelerate from low level disorder to extreme violence." Harris and the others are due to be sentenced on April 28.
