S1·E56 Episode 56

KEUNG discovers that YING had used the Automatic Banking System in the airport before the accident. He reckons that YING had been kidnapped by somebody she was familiar with to Fei Ngor Hill. The police investigates LAP. He denies that YING had been to the airport. He even lies that YING was not present in the spot. However, KIN does not believe in LAP. YUNG finds a letter copy written by YING to KIN. She gives the letter to KIN. The letter had mentioned that two witnesses had changed their statement against KIN. KIN suspects that LAP is the one who pushed YING down the hill so as to conceal the truth. The lawyer tells LAP that they could not charge LAP if YING is still in coma.
