The body of an American man was found bound, wrapped in a curtain and dumped in a trash heap in Phnom Penh’s Por Sen Chey district early this morning.

You Ma, from Phnom Penh Municipal Police’s toxicology department, identified the victim as 43-year-old US national William Glenn.

Khim Sarann, police chief for Por Sen Chey district, confirmed the case is being treated as a murder.

"We will investigate to find the killer,” he said.

One witness who saw the body before police arrived said the wrists and ankles appeared to have been tied with shoe laces.

In the mortuary at Stung Meanchey pagoda, Post reporters saw what appeared to be heavy bruising on the man’s chest and neck area.
