Investigation Into Fake Deceased Person Continues

An investigation into a historical case is ongoing, focusing on identifying a hidden suspect. Clues are limited as relevant individuals have been executed and the case is old. Investigators are seeking information about a person who may have placed letters in Li Meng's belongings. Di Qiao believes the clue regarding Che San has been eliminated, making the case extremely difficult to reopen due to the passage of time and the execution of related individuals. The possibility that the person who placed three letters in Li Meng's luggage might be an informant is considered, but finding them is deemed impossible. The group discussed the matter, finding no immediate leads. An investigation is underway to determine the truth behind a supposedly deceased individual, with the theory that the person is still alive. The source suggests that finding the real individual would clarify the situation. This follows a discussion where Wang Zhiwan proposed that the death of 'Che San' was staged and that the real 'Che San' is still alive.
