A Hunan man on trial for the murder of 12 women in Shenzhen said yesterday he did it because he knew there was 'no turning back' after he committed the first murder. Ma Yong, 43, and his girlfriend Duan Zhiqun, 20, from Sichuan, were tried yesterday at the Shenzhen Intermediate People's Court for the murder of 12 women job-seekers this year. The judges did not issue a verdict at the end of yesterday's trial. Posing as staff of a recruitment company, the pair allegedly lured the women to a rented apartment, where they robbed and killed them. Both Ma and Duan were charged with robbery and murder. They were arrested last month. Police found blood-stained clothes and identity cards belonging to the victims in the apartment. According to a victim's relative who attended yesterday's trial, Ma pleaded guilty but Duan denied the charges, claiming that she was forced by Ma to take part. 'The trial has explained some questions we have had in mind,' said the relative, who did not want to be identified. 'But the dead are dead. The trial cannot bring them back.' He said Ma could not explain to the judge why he killed the first woman over a small amount of money. 'But he did explain why he killed the rest,' the relative said. 'He said that after killing the first one he found there was no turning back and killing the next one became much easier.'
