Rae Ah, Kim Jae and Tae Gu watched the interrogation process behind a black glass that was only see through from one side.
The interrogation was conducted by Officer Kwon. Today they will interrogate Mahila's bodyguards, the owner of the hotel and room service who first found Mahila's body.
The interrogation went on for hours. But the three detectives did not find any light at all. The witnesses are clean and they all know nothing.
Room service also found Mahila while she was doing her duty and just then Mahila's hotel room was open.
"Hmm ... this is interesting. It seems that the perpetrator himself deliberately opened the door," said Moo Tae Gu.
