Seremban district police chief Mohamad Hatta Che Din said his department received information from the public about a foul smell coming from the locked house.

“Acting on the information, the police and fire brigade went to the house and cut the padlock of the gate. An inspection found three bodies in a state of decomposition in two bedrooms of the house.

“The investigation found that the three bodies were family members consisting of a 61-year-old man, his 59-year-old wife, and their 30-year-old son,” he said in a statement.

Hatta said a forensic examination found a cut on the right arm of the son, while there were no suspicious signs on the parents’ bodies.

“Also found were four knives with blood stains believed to have been used during the incident, and various types of drugs on the table in the living room,” he said.

The three bodies were sent to Rembau Hospital for a post-mortem to determine the cause of death. The case has been classified as sudden death pending the full post-mortem report.
