GEORGE TOWN - Sadistic murderers have no hesitation or remorse about taking a person's life and may even kill again, said Universiti Sains Malaysia criminologist Assoc Prof Dr P. Sundramoorthy.
Referring to the discovery of a woman's torso and arms stuffed inside a suitcase on Thursday, he said it was a gruesome act and "those involved do not have any respect for human life".
"They are ruthless. They may stop temporarily but there's a high chance that they will do it again," he added.
The remains, believed to be those of a foreigner, were found inside a bag in Jalan Kebun Bunga here. A post-mortem revealed the victim died of ligature strangulation. Her head and legs were severed after her death.
Dr Sundramoorthy felt the case might not be related to the case of another headless body of a woman found in the waters off Pulau Kendi last Tuesday as the modus operandi was different.
The second case seemed deliberate as the suitcase was placed near a popular hiking trail, he said.
On the rise in the slaying of Myanmar nationals in mainland Penang, Dr Sundramoorthy said it was a worrying trend with a significant number of murders in less than a year.
"Whether they are foreigners or not, that's not the issue. It could have been one of us. Crime is colour blind.
"We have not heard of anyone being charged for the murders until now. This is a troubling trend where the perpetrators were so bold and left the bodies behind on purpose to be discovered. It shows they have no fear or respect for the legal system," he said.
An anti-human trafficking activist, who declined to be named, said the murder of foreigners could be due to many factors such as ransom not paid to human trafficking syndicates, the continuation of inter-ethnic violence from Myanmar and involvement in fights or sexual violence.
He added that there were well-organised cross-border syndicates that smuggled Myanmar nationals, including women and children, out of their country.
