Cambodia News, (Battambang Province): On Friday, September 9, 2022, at 12:30, an American foreigner died at Trang Health Center in Ta Sen Village, Trang Commune, Kamrieng District, Battambang Province.
He was identified as CHARLES MICHAEL MC CALLION Male, 83 years old, Occupation: Casino Manager.

According to Khat Dara, a 31-year-old Cambodian translator, the US man was the manager of a casino in Phnom Proek district, but was staying at the Golden Hill Hotel in Kamrieng district when he slipped and fell in his hotel room at 6:40 p.m. on 9 September. He was hurt, but he refused to go to hospital at first.
Then, at midnight on September 9, 2022, he was in terrible pain so he took the car with the hotel driver to the Trang Health Center. He fainted when the doctor examined him, and died soon after.
An autopsy team consisting of representatives from the Battambang Provincial Prosecutor's Office, a team of doctors, immigration police, provincial technical police and the Kamrieng District Inspectorate conducted an autopsy and confirmed that the deceased had indeed died of a heart attack.
The body has now been handed over to the Technical Department for safekeeping at Wat Teuk Thla, Phnom Penh, waiting for the embassy to inform the relatives of the deceased.
RIP.

I think that contrary to the report, he in fact died upon the 10th of September at half past midnight.
