The police are focusing on the argument and drug overdose angles in probing the murder of 15-year-old Yap Xin Yuan.

“We are still waiting for the toxicology results to determine whether the deceased (victim) had taken any drugs.

“Until we receive those results (toxicology and post-mortem), we cannot confirm if she used drugs or overdosed,” said Selangor police chief Hussein Omar Khan.

He was speaking during a press conference at the Selangor police contingent headquarters today.

He said the victim’s body, discovered on Saturday in an advanced state of decomposition, also made it difficult for pathologists to ascertain any other physical injuries.

However, Hussein (above) did not rule out the possibility that the victim’s boyfriend might have been involved in disposing of her body.

“Whether someone else assisted in disposing of the body is still under investigation,” he said.

Previously, it was reported that police had detained three suspects aged 16, 20, and 51, including the victim’s boyfriend to assist with the investigation.

The teenager was reported missing after attending a lion dance practice at a basketball court in Batu 11, Cheras, on Dec 19, before her body was found at RTB Sungai Changgang, Kuala Langat, 10 days later.
