Chia Kee Chen was on Thursday charged with the murder of Mr Chua, a production technician, whose body was found among the thick foliage of a military training area in Lim Chu Kang on Jan 1.

Chia was said to have caused the death of Mr Chua at a multi-storey carpark at Block 429A, Choa Chu Kang Avenue 4, between Dec 28 and 29 last year. The 53-year-old accused is believed to have acted with at least one other unknown person, according to court documents.

The 37-year-old victim's body was found hidden in thick and tall grass near Sungei Gedong Camp after the police entered the restricted area during a search.

Mr Chua's family filed a missing person report on Sunday when he did not return home after leaving the previous day.

Mr Chua was apparently last seen along Cheong Chin Nam Road in Bukit Timah on Saturday, according to CCTV footage from a restaurant in the area, Chinese evening daily Lianhe Wanbao reported yesterday.

Officers from Jurong Police Division and the Criminal Investigation Department, however, managed to establish the identity of Chia, who later led them to Mr Chua's body in Lim Chu Kang.

Chia will return to court on Jan 9. If convicted of murder, he could be hanged or sentenced to life imprisonment.
