Subang Jaya (The Star/ANN) - Was William Yau Zhen Zhong abducted and killed or did he die after a tragic misadventure?
That's the question on the minds of investigators following the recovery of the six-year-old's decomposed body near Kampung Sungai Sireh.
Police are actively looking for clues into the case and re-examining all angles to find out how he died and how his body ended up near a jetty in Port Klang.
Among the theories are that his body floated about 30km down the Klang river from Kampung Bukit Lanchong (Please refer to map) after being thrown into it.
There is also speculation that the boy could have wandered off, fallen into a monsoon drain and ended up in the river.
However, there are no such uncovered drains where he was reported missing and the closest link to the river is about two kilometres away.
Although William's parents Yau Kok Kang, 32, and Goh Ying Ying, 26, identified his body based on the shorts and underpants he was wearing and scars on his head, police are still awaiting DNA test results, due to be released on Monday, to be 100 per cent sure.
"Post-mortem results could not determine the cause of death because the remains were too badly decomposed," Subang Jaya OCPD Asst Comm Yahaya Ramli (pic) said.
"But we have established that he had been dead for about a week, based on the level of decomposition," he said at the Subang Jaya police headquarters yesterday.
ACP Yahaya said there was no sign of external injuries except for some bite marks, believed to be inflicted by animals.
He said police had not ruled out foul play and were looking at the likelihood that the boy was dumped into the river.
"But it is still too early to conclude what happened to him," he said. "We are going to interview the boy's older brother again and are appealing for witnesses who had seen him to come forward. In short, we are exploring all angles," he added.
ACP Yahaya said police would comb the area where he disappeared in Putra Heights, the banks of the Klang river at Kampung Bukit Lanchong as well as the jetty.
Police have also recorded statements from the fishermen who discovered the body.
