Zaim Ikhwan Zahari, 30, said he had given his full cooperation to the police throughout their investigation into Zayn’s death and had trusted them to catch the killer.

“What I can say is that I’m disappointed with the police. I gave the police my trust to catch my son’s murderer. But my son’s killer is still out there.

“Is this the result (of their investigation)? So, I am naturally very disappointed.

“All these charges should not have been filed. It’s all nonsense,” Zaim, who was acquitted of neglecting his son, told reporters outside the Petaling Jaya court complex today.

While Zaim was acquitted by the sessions court, his wife, Ismanira Abdul Manaf, was ordered to enter her defence on a charge of neglecting her autistic son.

Ismanira chose to testify under oath from the witness stand.

The couple was charged last year with neglecting Zayn in a manner likely to cause him physical harm.

The alleged offence took place between noon on Dec 5, 2023, when the boy was reported missing, and 9.55pm the following day, when his body was discovered in a stream near their home at Apartment Idaman, Damansara Damai.

The charge was framed under Section 31(1)(a) of the Child Act 2001 which carries a maximum sentence of 20 years’ imprisonment, a fine of up to RM50,000, or both, upon conviction.
