KUALA LUMPUR, Feb. 21 (Xinhua) -- Doctors found no sign of puncture on the body of the Democratic People's Republic of Korea (DPRK) man, who died at Kuala Lumpur airport last week, as the cause of death is yet to be determined by results from a chemistry lab, said a Malaysian health official on Tuesday.

Medicolegal specimen taken from the DPRK man, which include fingerprints and dental ones, have been sent to a lab for further analysis to determine the cause of death, said Noor Hisham bin Abdullah, director of health in the health ministry at a press conference.
