At 4pm on October 24, a young man( aged from about 20 to 32yo according to the source) checked into O’Yes Guest House , No.C20 on the 3rd floor No. 17, Street 132, sangkat Srah Chok, khan Daun Penh. At 5pm on the same day, a young woman, aged about 25, came to join him in his room. She arrived on the back of a motorbike,( or possibly in a taxi, according to translation). Neither of these two people have been identified because they did not check-in and show their ID cards at the reception desk, but a security guard on duty at the time noted their times of arrival.
