Police investigating the murder of 40-year-old Sao Young have executed a search warrant at a Hamilton address this morning.

Sao Young's body was found at a rural property in Horsham Downs in April, sparking a homicide investigation.

The Armed Offenders Squad and Police detectives are currently at the scene in Casey Avenue where police suspect Sao was killed.

A forensic examination will take place over coming days.

Detective Senior Sergeant William Loughrin says a number of people connected to Mr Young have already been spoken to enabling Police to build a picture of his last movements.

'Mr Young was last seen alive on the evening of Thursday, March 12, in the Enderley/Fairfield area of Hamilton.

'We believe this was likely the night he was killed.

'His body was discovered at a rural property in Horsham Downs on Monday, April 13 - it was likely transported there after his death."

An investigation team of 30 people, including specialist staff, are working to help provide closure for Sao's family.

Sao arrived in New Zealand from Cambodia in 1992 and has been described by many as a gentle person who would not harm anyone.

Police would like to hear from anyone who may have seen him on March 12 or have information regarding his death.
