Forensic tests will be conducted on what two searchers believe are the remains of photographer Sean Flynn, son of Hollywood star Errol Flynn, who disappeared during the Cambodian War 40 years ago.

At least 37 journalists were killed or are listed as missing from the 1970-75 war, which pitted the U.S.-backed Lon Nol government against the North Vietnamese-supported Khmer Rouge.

Freelance "bone hunters" have also taken up the search for both missing journalists and U.S. servicemen listed as missing in Indochina. Some proved to be swindlers who demanded money from grieving families of the missing.
