KUALA LUMPUR: Police have completed investigations on the murder of an elderly couple in Kampung Sungai Penchala.
City police chief Datuk Allaudeen Abdul Majid said the cops will hand over the investigation papers to the deputy public prosecutor's office for further action.
Alaudeen said the motive behind the murders was due to money.
"Our investigation found that the motive was due to money.
"Checks on the suspect's background showed that he had nine prior drug records. When the suspect did not get money to buy the drugs that he wanted, he stabbed and murdered the victims. These were our findings," he told reporters after the city police's Deepavali celebration here today.
He said throughout the investigation, police called in 12 people to have their statements recorded.
He said the 12 people included those who had heard the commotion that occurred moments before the murder, and family members of the victims.
The couple was found after they were allegedly stabbed by their 42-year-old son during a fight in their home in Kampung Sungai Penchala on Dec 9.
The bodies of the elderly couple, aged 72 and 82, were discovered lying in a pool of blood in the living room of their house in the 7pm incident.
It was believed that a confrontation occurred between the couple and their son, who is believed to be a drug addict, before the incident.
The suspect was arrested at 10.30pm the same night by police at the Penchala Sprint Highway Tunnel heading towards Kuala Lumpur. He was later taken to the Brickfields police headquarters where he was tested positive for three types of drugs.
