Gu Chuchu and Yang Gang walked inside together, and by the way, they learned about the basic situation.

"The location of the disappearance should be the parking lot of the community, you also know where Consultant Qi lives, it is a very secluded community, and it has been used as a teacher's apartment for many years before, so the infrastructure is relatively old, and now there is only one surveillance video with a little clue, but this suspect has a strong sense of anti-reconnaissance, and we suspect that it should have something to do with Consultant Qi's life circle."

Criminal investigators have always been more cautious in their work, not to mention that Qi Sen is still a top professor.

"Could it be that someone deliberately retaliated in the previous case at the Public Security Bureau?" In fact, the most direct should be this matter, after all, there will be no contradictions in the school, and the most likely retaliation is the case that Qi Sen helped before.

Yang Gang nodded: "Yes, we thought the same at the beginning, but according to the current investigation, there are only three cases that are more suspicious." ”

Knowing that Gu Chuchu was Qi Sen's student, Yang Gang also let her participate in this matter, in addition to his excellent and rich clinical experience and knowledge, Gu Chuchu is also a top student in criminal investigation.

The first case was a case of abduction, and the initial goal was to lock on the neighbor, but Qi Sen analyzed the reasons for this matter comprehensively, and finally the relatives of the family thought of this way to find more money from the family in order to borrow tens of thousands of yuan.

And in the first case, there was a person who might have done such a thing, because after the matter became clear, the criminal's son dropped out of school and disappeared from everyone's sight.

The second case is to find out that a mentally ill person hurt someone, and this matter was about to be closed, but Qi Sen found that this psychiatric appraisal report was forged, and Dongyuan City also carried out a major reshuffle because of this matter, and this fake mental illness was naturally convicted, and the most emotional person at that time was the person's brother, and the brother knew that Qi Sen was the main person who changed this matter.

The third case is the matter of online reputation infringement, the weak party sued first, and then it was proved that all the rumors on the Yin Internet were released by this person, and Qi Sen from this person's usual words and deeds, said that Yin is a paranoid personality, if it wasn't for early warning, maybe that Yin Star would have been killed, and finally caught for intentional wounding, however, this case has been going on for many years, and it seems that this person has come out recently.

Gu Chuchu carefully read these three cases.

Yes, indeed, the three people here are suspected of doing this, and none of them are for money, either for themselves or for their families, the teacher came back because of the rehiring, and Gu Chuchu had to find a chance to go to school.

"Have you all been in touch?" Gu Chuchu asked.

"Li Siyin in the first case has gone abroad, we checked the nearest flight, and there is indeed no record of coming back, Pengfei in the second case has passed away, colon cancer, three years ago, the person in the last case has not been found yet, our people visited the place where he appeared recently, and he left a year ago."

So now the most suspicious person is Wu Yuan, Gu Chuchu looked at his photo and thought silently.
