He could not take any extreme measures against this couple who had lost their daughter either.
Inspector Liu handed him a document and said, "We managed to find some clues yesterday. We discovered one of Wang Lan's earrings near a harbor in the western part of Lin City. Moreover, we also found a witness yesterday and she testified that she saw someone who looked like Wang Lan board a yellow taxi at 28 Jinhai Road at Ye City. Then, we combed through the closed-circuit cameras along Jinhai Road and saw that Wang Lan had indeed boarded a taxi. However, when we approached the taxi company, the company said that this wasn't their taxi and the license plates didn't tally either. We found out that the license plate was fake after we dug deeper and the taxi had been taken from a scrap pile and re-modified. This shows that someone had been following Wang Lan for a while. We're still looking for this taxi and we hope to be able to track it down soon."
