Stuart Hazell admits during trial he killed 12-year-old Tia Sharp CRAYDON, England, May 13 (UPI) -- The British man standing trial for killing his girlfriend's 12-year-old granddaughter abruptly changed his plea to guilty on the fifth day of testimony. Stuart Hazell, 37, a window washer from Craydon, England, was charged in August with killing 12-year-old Tia Sharp. Ten days after the girl disappeared, her body was discovered inside a loft in her grandmother Christine Sharp's home. Police said Hazell raped and killed the girl then took sexually explicit pictures of her body. Hazell had maintained his innocence until Monday's stunning admission of guilt. Hazell's lawyer said his client wanted to make it known that "Tia's family have suffered enough and he did not want to put them through any further stages of this trial or this process." The jury was dismissed -- though all 12 opted to stay in the courtroom to hear the victim impact statements made by the family, The Mirror reported. Giving the victim's family the opportunity to address the court, Tia's mother, Natalie Sharp, said the pain of losing a child will be with her well after the trial is over. When the trial is done, it's all over for everyone else. It won't be for us," she said. I have so many questions for Stuart. I want to meet him. Sometimes I feel pity. Sometimes I want to hurt him. Outside the courthouse, Tia's father, Stephen, said he hoped Hazell will "serve his time ... then be hung." The judge said he will issue his sentence in the case Tuesday morning.
