KUALA LUMPUR: Police investigation into the murder of Zayn Rayyan Abdul Matiin is progressing in two phases, including identifying the mastermind behind the murder of the autistic child.
Selangor police chief, Datuk Hussein Omar Khan, said the first phase involved searching and gathering physical evidence at the crime scene and its surrounding areas.
For the second phase, he said the investigation would include inquiries and searches from house to house.
In this area, there are approximately 18 blocks comprising around 2,400 houses, Hussein added.
"We started yesterday until this morning in three blocks, and we will continue tonight and the following days," he told reporters at the crime scene today.
In the meantime, he said police had sent several case items obtained during the autopsy of Zayn Rayyan to the Chemistry Department to get forensic information.
"We hope to obtain results in the next two to three days, which can help the police get details that could lead to those involved (suspects).
"This is to obtain fingerprints, DNA (deoxyribonucleic acid), and we will also initiate a 'mass DNA screening' process that can help the police identify those involved," he said.
When asked about suspects, Hussein acknowledged with limited information, police would require more time to identify the mastermind behind the murder.
He also said Zayn Rayyan's murder was not a "straightforward" case, causing the police to need more information and evidence.
"At the moment, police have somewhat limited information to make any arrests.
"However, we can assure that the police will do our best to identify those involved and haul them to justice," he said.
Hussein also reminded parents that they are responsible for caring for their children, urging them not to neglect or leave them alone or in unsafe situations.
"Netizens are also reminded not to make statements that could jeopardise the investigation and share unverified information.
"This includes things that may offend family sensitivities.
"Do not worsen the situation. Have faith and give police space to investigate until those involved are caught," he said.
