It was determined that his name was Qi Gaoyang, and we immediately began to investigate and interrogate him, because the detective department could locate it based on the other party's mobile phone, so we quickly found out that the place where Qi Gaoyang worked was called Hongyu Publishing House, and Qi Gaoyang's file said that he was the editor of this publishing house.

When we went to look for him, we found that there was no one in the unit where he worked, and we consulted his editor-in-chief, saying that he didn't come to work today and didn't even ask for leave, and I didn't know what was going on.

Is this Qi Gaoyang because he committed a crime, so he was so scared that he hid, asked Liu Ming from the technical department, and he said that Qi Gaoyang appeared near the publishing house just now, but at the moment the mobile phone was turned off, maybe he turned back halfway when he saw you go to investigate.

I walked around the publishing house for a week and found no trace of Qi Gaoyang, so I guess this guy is really hiding.

In order to get more information about him, I went to the Guangzhou Lanyun Institute of Biology with Guo Meng, after all, he had been here that day, or asked the doorman here to remember anything.

When we came to the guard room, we consulted the old doorman, but he usually watched TV and took a nap when he was on duty, and he didn't observe the people who came in at all, and he didn't register all these people, so he didn't know that the bald man and Liu Qiulan had come to the Institute of Biology.

The doorman couldn't provide information, so we went to the old director, and after coming to his office to find him, I directly took out the back photo of the bald head to show him, although it was also the back, but the characteristics of this man's bald head should be easy to recognize, who knew that this time the old director was a little hesitant: "I'm not sure about this person." ”

I told him that the police used the Skynet system to find that he had contact with Professor Chen, and it was this person! I pulled out another picture to show him.

Finding out that it was him, the old director subconsciously replied: "This seems to be the parent of a researcher, although the Institute of Biology rarely has contact with the parents of the researcher, but this parent doesn't know how, and always comes to the Institute of Biology to find Chen Qiming." ”

"His name is Qi Gaoyang, right?" Guo Meng next to me followed my words and asked.

"That's right, it's this person, the bald head is easy to recognize, and the height is also easy to recognize, and few people are as short as them now."

"Did you see him visit his daughter at the Institute of Biology this morning?" I asked.

"No, didn't you look for him?"

Then we didn't find any other useful information on the old director, so we had to find Qi Gaoyang's daughter according to the information he provided, she was originally from Professor Chen's class, her name was Qi Xiaoguo, and her major was biology, and we chatted with her for a while, and she said that her dream of growing up was to be a singer.

We asked Qi Xiaoguo some information about her father's Qi Gaoyang, and she said that Qi Gaoyang had looked for her this morning and told her some very strange things.

I asked Qi Xiaoguo what he said, and Xiaoguo said that it was as if her father was going to run away, giving her money and telling her to study hard at the Institute of Biology.

In Qi Xiaoguo's mouth, we can almost conclude that this Qi Gaoyang is absconding in fear of crime, and it seems that we have to mobilize the entire Guangzhou police force to find out this criminal.

I told Zhuge Chengtian the news, and he said that he had asked the people from the technical department to fully follow up on this matter, and if Qi Gaoyang's whereabouts were discovered, they would tell us to arrest him.

The police sent someone to the Institute of Biology to step on the spot, I originally found out that Qi Gaoyang's wife was called Zhao Damei, and I was about to go to her, but I didn't expect Chengtian to call me and say: "He Xiao, when you come back now, there is a person who has come to the detective hall to turn himself in, and he said that he is the one who poisoned Professor Chen." ”

What the? I was a little surprised that Qi Gaoyang went to turn himself in, after all, he was still absconding before, he wouldn't turn himself in because he couldn't bear his own pressure, I didn't say much and drove the police car and Guo Meng back to the detective hall.

After that, I heard the news that Qi Gaoyang confessed all his crimes, Zhuge Chengtian told me that this Qi Gaoyang came to his biological research institute before Chen Qiming was poisoned that day, and he had that kind of contradiction because he had a monetary loan relationship with Chen Qiming before, once Chen Qiming said that he wanted to make any investment, and he needed 90,000 yuan to find Qi Gaoyang and ask him to borrow, Qi Gaoyang thought that Chen Qiming was his daughter's main professor, and whether his daughter could realize her ideal of becoming a singer in the future had a lot to do with him, In addition, although his usual editor income is not high, he still has 90,000 yuan in savings, so he lent Chen Qiming money for his daughter.

Later, Qi Gaoyang went to Chen Qiming to repay the money, but he didn't expect this guy to say that the 90,000 yuan investment failed and the money was lost.

Then Qi Gaoyang asked Chen Qiming for money several times, but he said that he couldn't pay it back, and once he threatened that he wouldn't pay back the money, and if he had his life, he would take it if he liked it.

Qi Gaoyang never thought that this Professor Chen seemed to be gentle and polite on the surface, but behind it turned out to be a scoundrel who borrowed money and did not pay it back, he was very annoyed by this matter, and he really wanted to take revenge on Professor Chen, who had a beastly face.

On the day of the incident, this Qi Gaoyang came to the Institute of Biology to ask Chen Qiming for money for the last time, he still said no, he was passing through the corridor with a teacup in his hand, and then a phone call came, he turned around to answer, before Qi Gaoyang couldn't get the money, he deliberately sniffed and asked Chen Qiming what kind of tea he brewed, why it was so fragrant, it was at this time that he took advantage of Chen Qiming's inattention to open the lid of the cup with one hand, and threw the rat poison into his cup with the other hand.

This call is really Chen Qiming's life-saving talisman, if it weren't for it, it is estimated that Chen Qiming would have discovered Qi Gaoyang's abnormal behavior a long time ago, since Qi Gaoyang had already surrendered, and he was only seen to have contact with Chen Qiming that day, then the murderer was naturally him.

Unexpectedly, this case, which caused panic in the Blue Cloud Biological Research Institute, was solved like this.

On the day when Zhuge Chengtian was going to write a summary of the case, he was reluctant to sign the summary book, and when I heard the news, I went to his office and asked him: "Captain Zhuge , why are you so hesitant?" ”

"Because I think there are still problems in this case, He Xiao, you and I go to the technical department, I have something to study with you."

Captain Zhuge invited me, of course I had to agree, so we came to the technical department together, and when I found Liu Ming, he also asked us what was wrong, Zhuge Chengtian said directly: "Then bring me the video of Qi Gaoyang and Chen Qiming in the corridor that day." ”
