National Forensic Doctor

Police Dog Squadron.

When Da Zhuang saw Jiang Yuan, he was too lazy to call out, so he raised his head to say hello.

If the dog doesn't take the initiative, Jiang Yuan can take the initiative, step forward, and shout first: "Captain Li, touch the dog."

Li Li, who was hiding in the kitchen scrolling through her cell phone, shouted without even raising her head: "Da Zhuang, please touch me."

Da Zhuang grinned, muttering something unknown, but still lowered his head.

Jiang Yuan jerked hard for a while.

The dogs brought by female police officers are generally clean and hygienic, and their fur is more comfortable to touch.

After having enough, Jiang Yuan went into the kitchen to fry rice again, cracked open the eggs, and explained to Li Li: "Yan Ge and Wang Zhong who are doing trace inspection are here, and Captain Wei from the Sixth Squadron is also here. "

"I thought you were willing to give up. Okay, as long as they don't pet the dog." Li Li was not only not unhappy, but a little happy. As a member of the police force, her police dog squadron has been marginalized for a long time. Usually no one comes here. It is really quiet and boring.

After a while, Jiang Yuan's fried rice was ready, and Wu Jun and Wang Zhong came over to order it.

After a while, a dark-faced old policeman came around from the other end of the courtyard wall. Before he could speak, Da Zhuang started barking "woof".

"This dog..." the old policeman laughed and cursed, then looked over and waved to everyone.

"Old Wei." Wu Jun also said hello, and when others walked in, he introduced to Jiang Yuan: "Captain Wei is the vice-captain of our sixth team, he is a veteran..."

"The vice-captain sounds nice, but it doesn't matter. You can call me Old Wei, or Wei Zhenguo." Wei Zhenguo's face looks dark from a distance, and wrinkled from a close look. His chin is also a little chubby. At first glance, he has been out in the field all year round. Recently, Wei Zhenguo has a dark face. It looks like he is gaining weight.

"Captain Wei." Jiang Yuan stood up politely.

In the county bureau, it is usually customary to give the title of deputy team to older police officers. There is no real power, no leadership position, and not even a cent more in salary. It just sounds nice.

"That's enough, Old Wei. I've heard people mention Forensic Doctor Jiang's name every day lately." Wei Zhenguo said politely again, and then said, "Does Forensic Doctor Jiang want to investigate the Wenxiang greenhouse arson case?"

Wang Zhong hurriedly said: "Just call Captain Wei for more details."

"Do you have any clues?" Wei Zhenguo looked at Jiang Yuan with half-open eyes. He has been here for half his life and already knows the level of technicians in the bureau. On the other hand, Jiang Yuan, although he was a newcomer, had outstanding performance in participating in two cases in succession, which made Wei Zhenguo feel a little interesting.

Wang Zhong recounted what was discussed yesterday.

Wei Zhenguo's expression became much more serious and he couldn't help but ponder.

"What do you think?" Jiang Yuan asked after waiting for a while.

"I understand your idea. You just want to identify a criminal suspect. Then, I will catch the person and deceive him again to see if he can confess." Wei Zhenguo summed it up.

Jiang Yuan and Wang Zhong looked at each other and nodded.

"It's not easy." Wei Zhenguo smiled, but shook his head and said: "You are right. The case was probably committed by people near the crime scene. Moreover, we took fingerprints back then. Now we are scanning Once again, even if you can't be sure, if you find a suspect, there is still a high probability that he will be able to fake it."

Jiang Yuan and Wang Zhong nodded again.

"We did it back then but couldn't find it." Wei Zhenguo gave the answer straightforwardly.

The two of them were stunned, and Wang Zhong couldn't help but said: "I didn't see it. It's not in the records either..."

"What you did today, can you record it after you finish it?" Wei Zhenguo said very calmly.

"Hey... this... hey!" Wang Zhong's disappointment was palpable. This plan was a strategy he had thought about for a long time, but he didn't expect that this road had already been walked by others and it proved to be unworkable.

At this time, Wu Jun looked at Wei Zhenguo and said, "Captain Wei, you are an old investigator. If you have any ideas, just tell me."

As far as Wu Jun knew about the detectives, veteran detectives like Wei Zhenguo, not to mention full of wits, definitely had quite a lot of ways to solve crimes that they had accumulated over the years.

Moreover, Wei Zhenguo must have some ideas about this arson case. Otherwise, he would have just refused on the phone. Why would he come to the police dog squadron to meet him. Da Zhuang doesn't let him jerk off.

Wei Zhenguo tapped Wu Jun with his hand and laughed: "Old Wu is still thinking more. I do have an idea and I feel like I can give it a try."

"You say."

"Criminals in arson cases generally don't commit only one crime. As far as I understand, people who engage in this scheme are addicted. Some people, even if they don't want to commit a crime in their minds, can light a fire He may not be able to control where and how it burns." When Wei Zhenguo said this, he paused for a moment, waited for a few people to clarify their thoughts, and then said: "Five years ago, the man who committed the greenhouse arson case At that time, I sorted out a few surrounding cases involving ignition and burning, and wondered if I could combine them, but the conditions were not very good..."

Wu Jun interjected and asked: "Can a case that was not brought together five years ago be brought together now?"

"I wanted to merge the case at that time. I thought that after the case was merged, I could find experts from the province to compare fingerprints. If Jiang Yuan could directly compare the fingerprints, he could arrest the person first and then consider merging the case." Wei Zhenguo solemnly said He said matter-of-factly: "Before I came, I checked again. Before the Wenxiang arson case, there were three cases in the surrounding area. They were all small cases. The value of the cases involved was hundreds of thousands of yuan, up to ten thousand yuan. Some collected Some of the incomplete fingerprints were not collected or were not collected. None of them matched the person. But I think these cases have something in common..."

Wei Zhenguo clapped his fingers and said: "First of all, Wenxiang is a remote place. Few outsiders go there. The crime scenes are all outside the town. It is likely that the crime was committed by locals, at least people familiar with the local area. Secondly, Wenxiang is a remote place. The number of arson cases in and around the country, four in three years, I think, is significantly higher than in other townships and towns in our county. Third, after the Wenxiang arson case, there were no more arson cases in the local area. It is likely that the suspect was arrested because of this. He ran away, which also explains why he couldn’t find anyone during the investigation.”

"Then, we just want to solve other small arson cases and see if they can be implicated in the Wenxiang arson case?" Jiang Yuan translated Wei Zhenguo's strategy.

Wei Zhenguo nodded and said: "My plan is actually similar to Xiao Wang's. It is all about circumventing and detouring. However, when we investigate small cases, it is actually simpler. Because there are cases, arrests and interrogations are all good. Follow the procedure. After catching the person, we will have a small case to hold it, and it will be easier to find out things. There is another thing, if I make a wrong judgment, at least the case will be solved, right."

Several people seemed much more relaxed and nodded in agreement.

In fact, Wei Zhenguo's plan was much more advanced than Wang Zhong's.

The old detective's strategy is indeed more mature.

"Let's eat fried rice first. After we're done, go back and look at the case." Jiang Yuan brought fried rice to everyone in high spirits.

Wei Zhenguo took a bowl of fried rice, looked at the orange-yellow rice grains, and said in a daze, "It's quite rare to treat someone to this."
