Before leaving the Linhe Cafe, Yan Tao called Xiaoxiao over and told her that her task in the past few days was to be with Shanshan and protect her safety.

Yan Tao also specially asked the bureau to allow Xiao Xiao to carry a gun 24 hours a day.

In order to confuse the suspect, Yan Tao went through the procedures for Cong Shanshan to be placed under residential surveillance, because a few days ago, Cong Shanshan and Duan Wenbiao did quarrel, and the quarrel was still very intense, and Cong Shanshan even said something like "I'm going to kill you".

Therefore, it is not impossible to say that Cong Shanshan is suspected of committing a crime, and Cong Shanshan herself understands that this is to protect her, so she naturally has no objection.

However, Zhuang Xiaoxiao's stay in Cong Shanshan's house was done in secret, and Yan Tao hoped that Cong Shanshan could become a bait and lure bigger fish to the bait.

He felt that Cong Shanshan and his reaction were very important, judging from the clues he had mastered, there was a big conspiracy hidden behind Duan Wenbiao's death and the demolition and relocation death case, which involved all kinds of complicated personnel relations behind Tiantai.

Back in the detachment, a series of messages were fed back to Yan Tao one after another.

First, after examining Duan Wenbiao's body and blood, the forensic doctor found that he had been injected with a drug that could cause his heart to contract rapidly, causing his body to suffer from severe hypoxia.

This drug is rarely used in clinical applications, and it is strictly controlled, and it is simply not available on the market.

Second, Zhao Sihai reported that they had found Duan Wenbiao's BMW X5, which was parked in the underground garage of his real estate company's office building.

Zhao Sihai has retrieved the surveillance video of Duan Wenbiao's various intersections from his villa to his office three days before his death, hoping to find out Duan Wenbiao's activities in the last few days.

Ten minutes later, Zhao Sihai returned to the criminal police detachment with the information obtained from the traffic police department, and directly knocked on Yan Tao's office.

Sitting in front of the computer, Sihai pointed to the freeze-frame screenshot and said: "This is a screenshot of a video of Duan Wenbiao's body waiting for a red light on the way from his villa to the company two nights before his body was found, that is, at 6:24 p.m. on May 9.

"But these sunglasses hide his or her face, but you see, he or she has earrings on his or her left ear, and they are very clear, the kind of diamond earrings that are rare on the market.

"This is a rich woman, and I suspect that she is Marjoram, so, boss, I apply to summon Marjoram and contact her directly."

Yan Tao nodded and said, "Okay, I agree, summon Ma Yulan immediately, and in addition, summon her nanny Liu Xiaolan at the same time, perhaps, she is also an important person."

"Also, notify the technical department to conduct phone calls on everyone on my list." After speaking, Yan Tao handed Zhao Sihai a list, and at the back of the list was everyone's phone number.

Sihai glanced at the list, and was obviously stunned: "Boss, these two people also want to be monitored?" Are they also suspicious? ”

Yan Tao nodded solemnly: "I'm afraid it can't be done, I'll explain the details later, in addition, send reliable people to the city's major hospitals to check the use of this medicine, focusing on the city people's hospital where Ma Yulan is located, this medicine is a new medicine, it can save people if it is used well, and it can kill people if it is not used well." ”

Yan Tao pointed to the name of the medicine with a long list of Latin letters written on another slip of paper and said: "This is the culprit who killed Duan Wenbiao, this medicine is very strictly managed, I believe that each hospital will have detailed computer records, it will not be too difficult to find out." ”

After a deep sigh, Yan Tao added: "This is a cardiovascular and cerebrovascular drug, which is rarely used in other departments, do you understand my intentions?" ”

Sihai smiled: "Boss, you also underestimate Sihai's IQ too much, your old man said it so clearly, I still don't understand?" Then I'm either mentally retarded or confused, hehe!

"That Dr. Ma is an orthopedic surgeon, right?" Sikai has regained the true color of a hippie smiley face.

Yan Tao smiled, he knew that this guy completely understood what he meant, theoretically speaking, all major hospitals in the city should check it to avoid omissions, but time is pressing, on the one hand, it is the requirement of the superiors to solve the case in time, and at the same time, the faster the action, the more the suspect can be caught off guard, so that he can not be well arranged.

If the adversary is given enough time, they may calmly destroy the evidence and re-respond to it, which will have a negative impact on the work of solving the case.

Therefore, such an investigation should be comprehensive and focused, which is Yan Tao's point to the four seas.

Before leaving Yan Tao's office, Sihai reported that according to the security company, the security monitoring facilities of Duan Wenbiao's house were replaced on the morning of May 8, and the original video materials had been destroyed according to the requirements of Duan Wenbiao's family.

Is it just a coincidence that Duan Wenbiao was killed between 10 and 12 o'clock on the night of May 8, and his body was found in the early hours of the next morning?

As soon as Sihai left, Guo Qiang also had news there.

Using Yan Tao's method, on the basis of clearing the periphery and collecting sufficient evidence, Guo Qiang carried out a policy attack on the two suspects who drove the bulldozer.

Guo Qiang put the two witness statements in front of him, looked at the younger of the two bulldozer drivers with contempt, and asked impatiently: "Tian Fu, you said that when you used the bulldozer to knock down the old man Wang Hongfa's house, you didn't know that there were people inside, right?" ”

Tian Fu pretended to be sincerely frightened and said: "I really don't know, captain, I have said everything that should be said, if I know that there are people in the house, can I deliberately kill people?"

"Is that still human? I was too timid to do something like that. ”

Guo Qiang smiled coldly: "Tian Fu, do you think you are still worthy of being called a human?" You keep saying that you don't know that there are people in the house, so have you been to Wang Hongfa's house at four o'clock that night? ”

Tian Fu was slightly stunned, and then denied it and said: "No, absolutely not, I have never seen that Wang Hongfa." ”

Guo Qiang stared at Tian Fu coldly, motionless, for two minutes, Tian Fu's cold sweat crackled down, and slowly lowered his head.

Only then did Guo Qiang say to Seinfeld: "Record our conversation truthfully, these will become evidence of the court's aggravated punishment for him, and until now, he is still making senseless denials."

"Tian Fu, I now have more than two witnesses to confirm that that evening, that is, at four o'clock, I saw you and Bai Dajun walk into the door of the old man Wang Hongfa's house together, and about a minute later, you had a fierce dispute, and the old man drove the two of you out with a stick."
