The investigation into the death of Canadian journalist and author Dave Walker continued over the weekend, with remains believed to be his taken to a Siem Reap hospital for closer examination, provincial immigration police chief Chao Mao Vireak said yesterday.

“The official of the Canadian Embassy from Bangkok and [Walker’s family’s] lawyer are cooperating with Cambodian police,” Mao Vireak said. “We don’t [yet] have any clue [as to the cause] of his death.”

Walker went missing on February 14. His remains were found on Wednesday evening by two boys near Angkor Thom.

In an interview on Canadian television, journalist Peter Vronsky, a friend of Walker, maintained that Walker had a relationship with Canada’s intelligence agency, advising them on the possibility of Khmer Rouge war criminals entering Canada along with refugees in the 1980s. He went on to say that a returned refugee suspected of involvement in Walker’s disappearance was a “senior Cambodian police officer”.
