A truck driver who raped a 13-year-old girl in 1999 was sentenced to 10 years in jail yesterday after police matched his DNA with an old sample found on the victim. Chung Chi-wing, 31, pleaded guilty in the Court of First Instance to one count of rape. The court heard that the victim, now 23, was unable to identify the defendant. But police found a match between his DNA collected in other investigations and an unidentified sperm sample that was put back into the government's DNA database in January last year. The database system was not established until 2000; samples collected before then only began entering the system a few years ago. Mr Justice Peter Line said the case was among the most serious of its kind. 'This is the kind of rape that must be met with the most severe sentence. Of course, for a single count of rape, 10 years is a long sentence, but the court will not tolerate what you did, and this is a crime for which the court will show no mercy.' He said Chung would have faced a 15-year sentence if he had not pleaded guilty. The prosecution said the girl was intercepted outside her secondary school in November 1999. Chung lured her into the back of a van parked nearby after pretending to be a policeman. The court heard that Chung then hit her on the head several times, forced her to lie down and raped her. The girl ran back to school and told her teachers what had happened, and they called the police. Rupert Spicer, Chung's defence lawyer, said his client had been the victim of domestic violence when he was a child. 'At 11 years old, he was beaten regularly by his father, several times a week,' Mr Spicer said. It was as a result of this that he then turned to God. But Chung continued to get into trouble, and was convicted of offences such as criminal damage and handling stolen goods. In a letter of mitigation submitted to the court, Mr Spicer said Chung hated himself for what he had done and was now unable to face his friends and family. He has an 11-year-old son and a five-year-old daughter. Chung's wife and the pastor at his church also wrote to the court in mitigation for him.
