Police order

Chapter 247 Peng Xiling

Going to communicate with Wang Tongwei, Yan Yu still called Lu Ling, she was not sure.Wang Tongwei is still being questioned at the apartment building, so Yan Yu gathered Lu Ling and rushed to this side together.

"Over the corpse, how do you feel?" After meeting, Yan Yu asked.

"I checked the situation of the second deceased. The second deceased was also a clean person, but he didn't have obsessive-compulsive disorder. He was a relatively normal person." Lu Lingxian raised a question, "Originally, I always thought that , the murderer killed the first person for revenge, deliberately got so much hair, and disgusted Liu Zheng. But judging from the second scene, this is simply to increase the difficulty of our investigation?"

"Which one do you think is worse in terms of relationship, the second person or the first person?" Yan Yu asked.

"I think the first person is better, after all, he has never stepped on two boats, and how many of the second one have stepped on?" Lu Ling said.

Yan Yu nodded: "We still lack the necessary information."

"Okay, let's not talk about this for now, about the corpses. The two corpses gave me the feeling that they were very painful. I tried to struggle but failed. I asked the forensic doctor. Although the cyanide poisoning is very fast, there is still a short period of sobriety. Yes. Generally speaking, it takes more than ten seconds to feel very uncomfortable. With this dose, you may fall into a coma in half a minute. During this short waking time, the deceased has a chance to see the murderer. And the two deceased gave My feelings are slightly different. The first deceased gave me more fear, and the second one naturally also had fear, but with a little more confusion. Although their remains are very painful, it is obvious that the second I feel that my death is unclear." Lu Ling said.

"You mean, if you do it, it might be the first person you have to deal with?" Yan Yu asked.

"No, I suspect that the first person didn't see anything at all, while the second person saw the murderer, but found that he didn't know him." Lu Ling gave his reasoning.

"As you said, none of the people we've seen so far is the murderer. The murderer doesn't know these two people." Yan Yu nodded, "This is also one of the mainstream inferences."

"That's right." Lu Ling nodded.

"Well, let's not go to Wang Tongwei for now." The four of them have already arrived downstairs in the apartment, Yan Yu thought for a while, "I'll take you to meet someone."

Liu Liwen and Wu Yuqiang followed behind without saying a word.

After the four of them reached the first floor, Yan Yu took Lu Ling and found a person in the computer room.

"His name is Peng Xiling, and he is a professional talent specially recruited by our provincial department," Yan Yu introduced to Lu Ling. "He specializes in electronic warfare, and this time there may be three groups of people."

The professional police are divided into three groups, the first and second groups are the criminal investigation group, and the third group is the computer group.The main job of the three groups is to fight against the increasingly rampant telecom fraud. If necessary, the three groups can directly attack some websites.

Peng Xiling usually doesn't talk much, but when he saw Yan Yu, he raised his head: "Sister Yan, are you short of people? I want to join the group."

"Huh?" Yan Yu laughed, "Are you so sure that we can get a set of titles?"

Peng Xiling didn't speak, and then fiddled with his computer.

"Did the surveillance here analyze any suspicious person?" Yan Yu asked.

"No, there are many surveillance cameras here, and they are closed," Peng Xiling pointed to the computer, "There are six exits in this building, only two of which are not locked, and only these two exits are monitored. , closed a month ago."

"what reason?"

"For the needs of epidemic prevention, when those doors are closed, the monitoring will also be closed, so that other monitoring can be stored for a longer period of time."

"The real estate here would use their brains to consider such a thing?" Yan Yu was a little skeptical, but did not continue to argue with Peng Xiling, "This case is not your strong point."

"Wait until you solve the problem." Peng Xiling spread her hands.

"By the way, have you connected with the property management?" Yan Yu asked.

"It's not something I'm responsible for."

At this time, Ye Wenxing called Lu Ling, but they didn't have any important progress, so they asked Lu Ling if he wanted to eat.

"Tell him, the team will deliver lunch later, let them go downstairs, let's discuss some matters, and then ask Wang Tongwei." After Yan Yu finished speaking, she led the people out of the computer room.

Ye Wenxing and Qingshan were upstairs, and when they heard Yan Yu's arrangement, they followed them downstairs.

Together, six people went to check the other four exits.

The four doors are all the same, all of which are electronic doors, and cannot be unlocked technically. Yan Yu then went to consult Peng Xiling, and Peng Xiling came out, looked at the doors here, and nodded: "It can be cracked, it is not difficult, this is Basic electronic locks can be opened with a Tesla coil. However, you have to check the connection, I am not a professional lockpicker.”

"This kind of lock is very cheap," Ye Wenxing looked at it. "Generally speaking, during construction, the door with this cheap electromagnet is installed with kickbacks."

Peng Xiling glanced at Ye Wenxing, and didn't know what Ye Wenxing was doing, but he didn't say anything, adjusted his glasses, and prepared to walk back.

"Besides the way he said, is there any other way to open it?" Lu Ling and Ye Wenxing asked.

"Violence can also be used to open the lock, and there is no need to destroy the lock." Ye Wenxing nodded, "Electromagnetic locks actually use electromagnets to hold the door together. This electromagnet can withstand a force of 280 kilograms. Because ordinary people do not have that much strength, it is not necessary to use force." It can’t be pulled open. However, if a relatively strong adult man hits it with all his strength, it can be opened without damaging the lock.”

"Qingshan," Lu Ling pointed at the door, "try it. Don't use too much force."

Originally, Peng Xiling was about to leave, but when he saw this, he stopped.He is used to solving problems with technology. He feels that this is an iron door, and brute force cannot solve the problem.

Qing Shan didn't say anything, he used his hands to push the door leaf, and after a little force, the door didn't open.

Then, Qingshan began to increase his strength, but the door was still very strong, and there was no sign of opening it.

I tried it, but it didn’t work. Qingshan changed his strategy, stood still about 20 centimeters away from the door, then straightened his body, and slammed into the door with his right shoulder.

The force that the electromagnetic lock withstood in an instant exceeded the limit, and it was opened directly.

Peng Xiling was taken aback for a while.

After the door is opened, it can be entered normally. When it is closed at this time, only a "click" is heard, and it is locked again.

If you want to open it again, you have to use as much force as before.

If this kind of electromagnetic lock is violently knocked open many times, the magnetic force will become smaller and smaller, which is commonly known as "broken". However, after a few short violent separations, the problem cannot be seen from the outside.

"So, the monitoring of those two doors is not acceptable. There are many ways for the murderer to leave through these four doors." Lu Ling said.

"The question is," Yan Yu looked at Lu Ling, "how did the murderer know that the monitoring of these four doors is closed?"
