Singaporean authorities have again disputed that Nagaenthran Dharmalingam was intellectually disabled and implied saying so was misinformation.
The city-state's Central Narcotics Bureau (CNB) argued that having a low IQ does not mean Nagaenthran had a disability.
"It should be noted that in the US, two persons were executed in October 2021. They had IQ ranges of 64-72 and 63-95 respectively, similar to Nagaenthran.
"The US Courts dismissed arguments relating to their alleged intellectual disability," the bureau said in a statement yesterday.
The bureau also said Nageanthran's lawyer M Ravi conceded he did not have the medical expertise to support his claim that the accused had a mental age of a person below 18 years old.
