Mu Zhiyang was ahead, walking with the momentum of six horses, leading Jiang Yuan and others along the way.

On the other side of the road, several police officers from the criminal police detachment stared at the vendors on the side of the road, hoping that the criminals would not bear the pressure and turned around and ran away.

In fact, this kind of road blockade is often handed over to the police station police, or other criminal police officers from two teams are arranged to arrange for two teams of non-project teams.

But this has come to the last step, and it is time to arrest him. Anyone who is willing to give up the great achievements is just to save some effort.

On the contrary, the criminal police officers of the Criminal Police Detachment of Zhengguang Bureau are now at their peak.

It is no longer rare for Jiang Yuan and Jiang Yuan’s special team to solve murder cases, but for ordinary criminal police detachments, arresting murder suspects is always a rare opportunity.

In fact, Mu Zhiyang is quite rare.

He took the lead, raised his chest and looked up at the stall selling roujiamo on the street. He stared at the kitchen knife that cut meat in his hand, and said, "Boss, we are from the criminal police team, please ask you a few questions."

"I heard that someone is dead?" The boss was a short and thin man. He chopped the kitchen knife into the chopping board with a thump, and asked Mu Zhiyang instead.

"Where did you hear it?" Mu Zhiyang did not answer, staring at the boss and his kitchen knife with sharp eyes.

Wen Yong stepped forward, held the handle of the kitchen knife, and took it into his hand.

The short and thin Roujiamo stall owner laughed out loud: "It makes you nervous - we have a group of people. I heard that you were doing inspections or something. I was going to run away, but later I said it was not urban management. By the way, do you eat steamed buns? One is 8 yuan, so I can pick up some more meat for you."

"No need now." Mu Zhiyang lifted up the crotch cloth under his stall and looked at him and asked, "Do you still have a knife?"

"No, we are all conquering the world with one kitchen knife-"

"Didn't you pick a knife or something?"

"I use all the best pork belly, look at it." The thin Roujiamo boss said, then picked up the spoon and grabbed the meat from the pot for several people to show.

Jiang Yuan stepped forward at this time and said, "Where were you last Tuesday morning?"

Laboratory reports have been released one after another, and Jiang Yuan also reopened the "temporary +1" to judge the time of death.

As of now, Jiang Yuan can shorten the victim's death time to within two hours in the morning.

If this is the case, the time when the murderer kills people should be shorter than the time when the mobile phone signal disappears. In other words, the mobile phone is likely to be handled by the murderer, and the time when the deceased is hijacked is also very short.

To describe it in a less pleasant description, the murderer had been hijacking the victim for several hours,

It should be always busy.

No matter when the household is thrown, just killing people and dealing with household bodies, or dealing with mobile phones,

It will take a long time, so the evidence of absenteeism on Tuesday morning is very important and the key to the police screening these food sellers.

The owner of the Roujiamo stall smiled without much care: "Where can you go, just sell Roujiamo here."

"What time is it to what time?" Mu Zhiyang turned around and took out his notebook to make records. He was also a detective.

"I usually arrive at around 6 o'clock in the morning. When someone opens, they open it. If there is no one, they will organize something first, then start takeout, and then chop meat and do it until the afternoon rest, and then continue to do it in the evening. My wife buys meat and cooks meat at home, and she is very tired-"

"From 7:00 a.m. to 1:30 p.m.? Or 6:30 a.m. to 1:30?"

"It's almost the same from 6:30 to 2:30. Some takeaways are very late now-""

"When I was with you at that time, what other vendors did you notice? Which ones were opened?" Mu Zhiyang continued to ask. These questions were to be thrown to each merchant. Let's compare the transcripts with each other.

If someone talks nonsense, it can be easily discovered.

Correspondingly, if several people can prove someone's absent, he will basically be cut out from the list of suspects.

For the police, it is important to list the suspects, and it is even more important to narrow the list of suspects. However, once the mechanism is wrong and the wrong screen is selected, and the suspect is missed, the entire list will be considered to be finished. This is the case in both the silver case and the gold case.

Mu Zhiyangwen asked a few questions and then marked a star on his notebook.

Even if this is basically eliminated, this is just a score given by Mu Zhiyang. Wang Chuanxing and Liu Jinghui will also give each score and choose whether to exclude it.

The current list of suspects is more than 60 households, with less than 200 people. All of them are screened. If a high suspicion can be screened out, even if this set of screening ends perfectly, whoever wants to write an article in the future can do it.

But if you can't sift out, you need other means. For example, technical investigation mobile phones, image investigation and surveillance,

And they only need to report their positions on the list.

Nowadays, people basically keep their mobile phones away, and on the ground of the capital, the number of base stations is enough to perform triangular positioning in most places. Such information at a certain time is the easiest job for technical investigation.

Similarly, if you use surveillance to find a criminal, you don’t have time to find a place, so it is naturally difficult to find it. However, it is too simple to ask each suspect to report that intersection he passed at a certain time period and then investigate and verify it.

As for the reason, if someone is unwilling to say it, or if the time and place are not found, the surveillance level is just raised.

In ordinary cases, two criminal police officers may be sent, or a squadron and a few people from a brigade are investigated.

More than 60 suspects have a bit of workload, but they fall into Jiangyuan's special case team, which is 30.

There are many people, and then they are randomly assigned to a brigade, and there are about 20 people. Even if half of them are dispatched to come, some people will be arranged to block the intersection, conduct on-site investigations, and protect Jiang Yuan. The remaining two and four people are in a team, and there will be no few suspects.

Jiang Yuan followed Mu Zhiyang to check the owner of the Roujiamo stall, then checked the owner who set up a stall to sell French fries and fried chicken. When he wanted to walk forward, he found that the street had been questioned, and the remaining two or three vendors were surrounded by police several times his own.

"Change a street?" Jiang Yuan asked.

"It's gone, it's just that big. We came out together. There is a small vegetable market three kilometers away and we've almost finished asking." Liu Jinghui has been paying attention to the progress in all aspects.

Jiang Yuan frowned, looked at Liu Jinghui again, and asked, "Isn't a cooking person? A pharmaceutical company? A chemical factory?"

The benzoic acid and acrylamide found before are also useful in medicine, but the content in the medicine is too small, so it is unlikely for people who take the medicine to come into contact with it directly, and then they will have some on the plastic tape again. Jiang Yuan is actually not sure about the chemical factory that can be touched in large quantities. Not to mention anything else, the current small workshops know that they wear gloves when they come into contact with these chemical raw materials.

Liu Jinghui said: "I checked it. There is no chemical factory near Jinshan that uses these two raw materials at the same time. In fact, even if it is used at the same time, it may not be possible to be accessible to one person. I also checked chemical stores and other things.

There are no such stores nearby. If not, just expand and look at their sellers and suppliers, but don’t worry.”

"Why?"

"Is there any vendor who set up stalls? I have someone come to find them."

"Okay." Jiang Yuan couldn't help but nod. The suspicion of food vendors who did not set up stalls on time increased greatly.

"Stand up a little bit, is this your box?"

In the distance, Xiao Si's voice rose several degrees and came from afar.

Jiang Yuan and others couldn't help but look over.
