The body of a missing American woman was discovered in the popular Sihanoukville tourist destination of Koh Rong on Monday, police said yesterday.

Katherine Ann Grgich, 55, disappeared on September 28, after checking into Island Palace Bungalow Resort for a five-day stay.

Oum Sam Ol, provincial deputy police chief, told the Post that following the discovery of Grgich’s body, local authorities alongside US Embassy officials and a local medical team examined the body and found no signs indicating murder or rape.

“The body was decomposing and cremated on Tuesday with the US Embassy’s agreement. The remains will be given to the embassy on Thursday. The police have not come to any conclusion yet [on the cause of death],” he said, adding that a team of representatives from the provincial crime department, central justice police and local police would continue investigating.

Grgich arrived in Siem Reap International Airport on September 23 and checked into her hotel on the same day, Sam Ol said.

Sean McIntosh, US Embassy spokesman, offered few details on the case but confirmed the embassy was in the loop.

“The US Embassy confirms that the body of an American was found on Koh Rong and we have requested the relevant authorities to conduct a thorough investigation,” McIntosh said.
