An accused killer's claim that loan sharks forced him to take part in the murder of three prostitutes was not a lie dreamed up by a desperate man, the Court of First Instance trial was told yesterday. In his closing submission, barrister Andrew Bruce SC told jurors that there were 'no irrefutable facts' in the triple murder case against Nadeem Razaq, 24. Jurors must acquit the defendant if they believed it was possible that another man of Pakistani origin, named Tony, had committed the murders in a two-day killing spree in March. Mr Bruce noted that Razaq's DNA was not found underneath the fingernails of one victim who had allegedly scratched his arm. He also dismissed suggestions that a cash-strapped Razaq picked three prostitutes at random to rob and murder. At least two of the victims appeared to have significant assets and may have been targeted by 'gangster' loan sharks out to collect debts. 'The prosecution's case was that a single actor, a single killer, picked three mainland women at random who have got some money,' he said. 'What do you think the chances are? Was it pure luck? Possible. But the prosecution's theory makes the least sense,' Mr Bruce said. Razaq had first told police that he strangled the victims so Macau debt collectors would forgive his HK$150,000 gambling debt. He testified he had not killed any of the women, but rather used their services so he could give the real killer access to their flats in the New Territories. Razaq pleaded not guilty to three counts of murder in the strangulation deaths of Tse Hau-yuen, 35, Sze Ming-lan, 35, and Sun Xiumin, 30. Earlier, prosecutor Arthur Luk Yee-shun SC had argued that there was no evidence that Tony and a trio of debt collectors were real, he added. Jurors are expected to begin deliberations on Tuesday after receiving legal instructions from Madam Justice Clare-Marie Beeson.
