Yan Tao frowned and didn't say anything.

Zhao Sihai looked at him and continued to report: "I contacted the Institute of Chemistry, and they said that Professor Shi's affairs are mainly in charge of Director Wang of the Office of the Institute of Chemistry and Professor Shi's assistant Sima Qiao.

"I have also told you about the situation of these two people, they are both at the airport, I sent someone to the airport, but instead of contacting them directly, I paid attention to observe if there was anything abnormal.

"In addition, we compared the fingerprint traces of the other three men and one woman who stayed in Professor Shi's room, one of them was Sima Qiao's, the other was Song Bo's, and the other two men and women we suspected were Shi Muzi and Sun Mei's, but there was no comparison, so we couldn't confirm it for the time being.

"DNA samples of hair, dander, and bodily fluids that you collected on the bed in the other two rooms also came out, and the DNA of the male on one of the large beds showed that there was a parent-child relationship with Professor Shi, according to Tang Jia's statement, this should be Shi Muzi and his wife, and there was no trace of anyone else.

"The other bed is sometimes where Tang Jia rests, and her computer is also in that room, where the woman's DNA sample shows that Tang Jia's, but there are two other men's hair, body fluids and dander, which is a bit unusual, because there are no samples, we can't tell whose it is.

"That kind of bodily fluid stain has been proven to be the semen of two different men, which can basically confirm that Tang Jia is having an affair with other men.

"Comparing the men who often go in and out of Professor Shi's house, excluding Song Bo, that Sima Qiao needs to be further compared. This indicates that there is also an unknown man who once slept in Tang Jia's bed and left semen/fluid.

"Through the examination of all the remnants of Professor Shi's bed and under the bed. It shows that they are all the body fluids and body residues of Professor Shi himself and Tang Can. ”

After listening to Zhao Sihai's return. Yan Tao nodded: "The work of the technical department is very effective, if the case is solved, I will give them credit." Now I will share with you what I have now. ”

Yan Tao told everyone about the information he had learned from coming into contact with this case and the results he had just sorted out, and finally he concluded: "Based on the above information, I think that although Professor Shi's death is not based on the final forensic report, we analyze that most of what Tang Jia said is the truth.

"It is likely that the cause of death is sudden death caused by cardiovascular and cerebrovascular problems caused by overindulgence, after all, it is a rare age. Judging from the tissue paper left at the scene and the items stained on it, it is likely that under the influence of drugs, Mr. Shi would have such abnormal behavior.

"These, when the autopsy results come out, there will be a conclusion, my suggestion is to contact the forensic office, let them prepare, and strive to do the autopsy as soon as possible after Professor Shi's family arrives, so that we can carry out the next step of the work as soon as possible."

After speaking. Yan Tao asked for everyone's opinions with his eyes.

There was no objection.

He nodded and said, "This matter is settled, and I will call the staff on duty in the forensic office later and ask them to contact the forensic doctor on duty and get ready."

"Here's what I'm going to say. Now it seems that Professor Shi's death, whether it was a natural death or a murder. It's hard to separate from his very valuable collection, in other words. He was surrounded by people who coveted his collection.

"Our next work will focus on these two aspects, on the one hand, the cause of Professor Shi's death. On the one hand, it is to find out who touched Professor Shi's collection.

"According to the existing clues, I have identified such a few suspects, let's analyze it, and if there are any objections and additions."

Yan Tao handed Huang Miao a piece of paper with several names written on it, and said, "You can pass it on." ”

Zhao Sihai and Guo Qiang leaned their heads over.

Yan Tao's paper has such a name written on it: Tang Jia, ? , Sima Qiao, Shi Muzi, Shi Muyun, Shi Muwei, Director Wang of the Institute of Chemistry, Song Bo,.

The second is a question mark.

Huang Miao raised her head suspiciously, pointed to the question mark and asked, "What does this mean?" ”

Yan Tao smiled: "I can only think of these seven people now, but I suspect that there is likely to be an eighth person, or even a ninth person, because it is not yet certain, so I have to use a question mark to indicate it."

"I have two bases for this: First, this morning, Tang Jia left the hotel where he was temporarily staying for three and a half hours.

"There is no problem for her to leave the hotel, the public security authorities have not taken coercive measures against her, there are no restrictions on her personal freedom, and she can leave the residence.

"But she lied, and we found out from the surveillance video that she left the hotel at 10:35 a.m., but she said she went out at 12 o'clock.

There was a time difference of nearly two hours, what did she do during this time? Whether it will be someone in private is an important doubt.

"Suppose she really went to meet someone, who was that person? Could it be someone from our list above? The odds are extremely unlikely.

"First of all, Song Bo can rule it out, I called and asked the people of the Linhe Branch, and Song Bo's statement is basically the same, Song Bo stayed in Professor Shi's mourning hall last night, went home at seven o'clock this morning, took a shower, ate something briefly, changed clothes, and arrived at the unit at eight o'clock.

"This was also confirmed by the personnel on duty today of the technical brigade, who had been resting in the technical duty room, where he had lunch until I looked for him, and he never went out in between.

"Secondly, Sima Qiao and Director Wang of the Institute of Chemistry went to the airport at about 9 o'clock in the morning, and because the flights of Professor Shi's children could not be determined, the leaders of the Institute of Chemistry ordered them to stay at the airport, which was also confirmed by people from the Linhe Branch.

"As for whether it is possible for Tang Jia to meet the professor's children, this possibility is not impossible, because we have no way to confirm their whereabouts yet, but the possibility is very small, and the reason is clear to everyone.

"Therefore, if Tang Jia used those two hours to meet someone in the morning, in this case, this person is very suspicious.

"Of course, we can't rule out that Tang Jia did something else unrelated to the case, so this is just an assumption.

"Second, as Sihai said just now, on the bed where Tang Jia often rests, two men's hair, semen/fluid and dander were found, who are these two men? How could you leave those things on Tang Jia's bed? ”

"Based on the above two points, we can't rule out one or two men who have a private relationship with Tang Jia that we don't know yet, so I used a question mark, and this question mark is in second place, only behind Tang Jia, if he exists, he will be an important suspect."

After listening to Yan Tao's explanation, everyone also felt that it was very reasonable, it was indeed very likely that there would be such an invisible person, who had not yet been taken into sight.

Immediately, Zhao Sihai raised another question: "Master, is Song Bo also going to be listed?" He's one of our own, huh? ”

Yan Tao shook his head, looked at Huang Miao and Guo Qiang, who were also looking at him with puzzled expressions, and said, "Have you forgotten a word?" All are equal before the law!

"We don't care whether we can really be equal in reality, but we must do it equally, and we can't replace the law with feelings and personal likes and dislikes, as well as status.

"Yes, Song Bo is a member of our detachment, but don't forget, he is also a close disciple of Professor Shi, a person who often goes in and out of Professor Shi's house, and one of the few people who have had access to Professor Shi's collection, so we don't have any reason to treat him alone.

"Even if I am involved in any case one day, I still have to recuse myself, and you should not ignore the investigation of me because of favoritism, which is not only respect for the law, but also respect for the parties, only after review, it is proved that he has nothing to do with the case, and we can return his innocence."

Guo Qiang pointed to the names of Shi Shude's three children and said, "Yan Da, as soon as this Shi Muzi couple returned to China, their father had an accident, and they really have a suspicion that they can't escape."

"However, this Shi Muyun and Shi Muwei sisters were still in the United States at the time of the incident, what suspicion will they have?"

Yan Tao shook his head: "Guo Qiang, you have always been a thoughtful person, how can you also make preconceived mistakes?" So far, what evidence is there that they were in the United States at the time of the incident?

"If you say that, can't you also think that Shi Muzi and his wife were in Jianghuai at that time? More than 2,000 kilometers apart, they shouldn't be suspicious? ”

Guo Qiang patted his head: "Yan Da, I did have a preconceived idea and committed a big taboo in handling cases." ”

Yan Tao nodded and said: "Even if they are really in the United States, it cannot completely rule out the possibility of their participation in this matter, and the repeated changes in the flights of Professor Shi's son and two daughters today also speak for themselves."

"Although we have no evidence to prove what caused the people from the Institute of Chemistry to pick up the airport since the morning, and there is no news yet, we must find out where they have been in the past few days and what the pattern of their activities is.

"So my idea is that we must increase the investigation of the airport, and find out what airport they took off from, when they arrived in China, and what actions they have taken in China.

"Of course, there is no urgency in this matter, and it will not be too late for us to check when they arrive, because we don't know which country's passport they hold and what the name on the passport is."

After speaking, Yan Tao looked around at the three people and said, "Do you still have any questions?" ”

The three of them shook their heads in unison.

"So do you have anything else to add, such as what I left out, and what do you think needs to be added?" Yan Tao continued to inspire the three of them.

The three of them pondered at the same time, and after a few seconds, Guo Qiang raised his head and asked, "Yan Da, just now, I heard that you specially introduced a woman whose name seems to be Lin Mei before Professor Shi in front of Tang Jia, right?"

"It is said that this Professor Shi is amorous by nature and has had many women, why do you only mention her, what is the deep meaning?" (To be continued......)
