Earl's son accused of rape is naive, like a teenager, says sister He tries very hard to be responsible. He takes responsibility seriously - it's part of his caring and kindly nature. Mr Murray gave evidence yesterday. Asked by Nicholas Syfret QC, defending, whether he had any concern about being a 41 year-old having sex with a 16 year-old he answered: "Yes. I had deep feelings of unease throughout, yes. He said the girl, a foster child, had "installed herself" in his home after helping him identify who had stolen bicycles from the block of flats. Mr Murray said the girl was staying in his spare room. "I felt she was expecting me to initiate sex with her, so I did," he said. "She said, 'OK, I can do that." "" Mr Murray, who denies rape, said the girl did not object. He is accused of having intercourse with her after getting her drunk on vodka. He insisted that the intercouse was consensual. "Did she object in any way to what you were doing?" asked Mr Syfret. "No," the defendant answered, adding that she was awake throughout. Mr Murray said the condom he used broke and the next morning he suggested that the girl take a morning-after Pill. He said the girl's friends arrived and the mood became "aggressive and confrontational" and they were asking if he had "done something" to her. The group left and Murray was not allowed to speak to the girl, but he phoned her and sent her text messages that afternoon, apologising 21 times. Yesterday, he said he did not know what he was necessarily apologising for. He sent one text telling her if she called "the police and cried rape saying I spiked your Ribena our friendship will be over." The girl was one of a group of teenage friends who would visit Mr Murray's home to drink, smoke, play on his laptop and listen to music, the court heard. Tim Clark, prosecuting, asked Mr Murray: "Isn't the reality you had been grooming this teenage girl?" "I thought she was grooming me," he replied. The teenager lived with foster parents and would run away from home because of problems in her family life, the court heard. On one occasion, Mr Murray wrote her foster parents a letter apologising when police found her in his home after she went missing. He wrote of her having problems settling in Oxford and said: "I'm sorry if you feel that I've contributed to any problems that she has."
