"The postmortem examination found the woman died of strangulation," one police officer said. "But the pathologist cannot be sure of the exact method used by the killer."

Marks were found on the neck of Arbe Chan, 26, a Dragonair flight attendant, when her body was found inside the wardrobe of her family's flat at Allway Gardens in Tsuen Wan on Sunday.
Although police believe she was killed while alone at home on Wednesday last week, the officer said the autopsy could not confirm the exact time of her death.
Chan's 25-year-old former boyfriend is the prime suspect in the murder case after he was captured on CCTV last week at the building where she lived.
Police are seeking help from mainland authorities to trace the Hongkonger after immigration records showed he left the city for the mainland via a land crossing on Saturday. Yesterday, a police spokeswoman said no one had been arrested in connection with the murder.
