Melaka police chief Dzulkhairi Mukhtar said the suspect would be brought before a judge for a remand order tomorrow, Astro Awani reported.

He said the suspect’s 51-year-old mother, who was a teacher at a Chinese school, and 21-year-old brother were found in the living room of their house with multiple stab wounds.

Another victim, the suspect’s 13-year-old sibling, was found alive but injured and covered in blood in the garage of their home.

Early investigations suggest that the suspect was likely emotionally distressed due to pressure to excel academically.

“Perhaps because the mother was a teacher, she wanted her children to achieve excellent results. The suspect was due to sit for the Sijil Pelajaran Malaysia (SPM) examination this year.

“He was likely often scolded and told to study harder. Neighbours reported frequently hearing arguments from the house,” Dzulkhairi told a press conference at the Melaka police headquarters.

According to Dzulkhairi, the suspect is believed to have attacked his mother while she was in her bedroom. The older brother is said to have rushed to her aid, leading to a struggle that resulted in both victims being fatally stabbed.

“The suspect then allegedly ordered his younger brother to leave the house, but the boy refused. The suspect then attempted to stab him as well.

“Although seriously wounded, the younger sibling managed to escape and was later rescued,” Dzulkhairi said.

He said the suspect had attempted to dispose of evidence by discarding his clothes in nearby bushes.

A folding knife, believed to be the murder weapon, was found in the suspect’s school bag in the garage.

The suspect’s younger brother has been sent to Hospital Melaka for treatment.

The bodies of the suspect’s mother and older brother have been sent to the forensics department of the same hospital for a post-mortem.
