National Forensic Doctor

"Could it be that the tires were changed? He borrowed his uncle's motorcycle. Does uncle usually ride motorcycles? Maybe the tires were changed in the meantime?"

Wu Junhao is still very concerned about the criminal suspect Li Jiansheng. His mother didn't act like an ordinary old lady either.

Wang Chuanxing, who knew the situation better, came over and said: "Li Jiansheng's uncle only rides a motorcycle occasionally. He only goes out once a month or two. But the tires were changed last year. I have already found them at a car repair shop near my home." The boss knows the situation. Therefore, unless the criminal changed the tires himself, there is a high probability that this car is not the vehicle responsible for the crime."

"There is no need to borrow a car to commit a crime." Liu Jinghui said: "A motorcycle is not a car. There are many ways to conceal its origin. There is no need to borrow a car. It is difficult to change the appearance of a borrowed car. Moreover, the criminal did not take the motorcycle too seriously when using it. He pushed it down on the roadside at will and entered the wild road without caring about scratched paint and other problems. This does not conform to the logic of borrowing a car."

Liu Wenkai next to him said: "You can stand up and pedal on a borrowed bicycle, but you can't injure the leather surface, as it may make the original owner unhappy."

Liu Jinghui took a serious look at Liu Wenkai and said: "It's almost the same logic. All in all, the price of a motorcycle is not high compared to Li Jiansheng's income. If it was a motorcycle used to commit crimes, he would not have used it for at least three consecutive years. Fixed time loan.”

The last reason is easier to convince. Wu Junhao couldn't help but nod. The criminal may not be aware of the problem of refueling, but the concept of crime time has long been deeply rooted in people's hearts. Many innocent cases are determined because of "no crime time". Logically speaking, the criminal will not be in every day. There is no need to borrow the same person's vehicle before committing a crime, even if it belongs to an uncle.

Buying your own car, keeping it there and using it when committing crimes is the most appropriate solution.

Wu Junhao's eyes narrowed and he said: "Did he notice the problem of refueling in advance? For example, he drew gas from other cars."

"This possibility cannot be ruled out." Liu Jinghui had obviously thought about this issue and looked at Xu Taining.

Xu Taining had been silent, and then he said: "Case-solving, especially investigation, is to look for opportunities from the criminal's flaws. If the criminal has no flaws, the case may not be solved."

"Then we want to change the direction?" Someone immediately asked.

Solving a crime is a bit like making a movie. Before the shooting starts, preparation is a cost. Once the shooting is started and the crew (project team) is up and running, it is another cost. The most expensive part may be when the finished product is produced. The romantic long shot, the red skirt and the flames, the innocent smile from the overhead perspective, and the wonderland that does not exist in this world are all 100% cost.

If the direction is really wrong, it is better to correct it in time than to delay it.

But is the direction really wrong?

This is an issue that Xu Taining needs to consider carefully.

"There are still many people on the list who have not been asked." Xu Taining first looked at the expressions of the policemen from the Qianjin District Bureau, then looked at Jiang Yuan, and said: "It's not that the criminal can't avoid these questions, but based on the criminal's previous crimes, Judging from his experience, I'm afraid he is still an emotionally driven person, but the techniques he masters and the methods he uses are rather special."

This is actually Xu Taining's profile of the criminal's identity, but it's just not that detailed.

Based on Xu Taining's understanding of this case, if the criminal commits another crime again, there is a high probability of being caught. The failure to solve previous cases was due to a certain degree of chance, especially since the victim took a shower every time, which was very inconvenient for the extraction of DNA and other evidence.

However, the last direction this investigation should take is to wait for the criminal to commit another crime.

Thinking of this, Xu Taining said: "I don't think there is any need to adjust the current investigation direction. If at the end of the investigation, there are still no clues about the criminal, this is also a clue in itself."

"I thought you were going to tell the truth." Liu Jinghui laughed and said, "Then continue the investigation. There are still many people on the list who have not been fully investigated. Let's move on after the list is cleared."

"That's it, Captain Lei?" Jiang Yuan looked at Lei Xin.

"Suffer it." What can Lei Xin say? If we talk about suffering, he is really suffering. However, he is actually used to it. Since the investigation of this case, he has changed the direction of investigation several times, so no matter Whether Xu Taining changes the direction of investigation, Lei Xin can accept it.

"I'm going to check on another person who went abroad." Wu Junhao volunteered, bringing one of his team members with him, and also a local criminal policeman.

On the list, two people were overseas. Wu Junhao investigated one person. Although the other person, Lu Xuekun, settled in Qinghe City, his mother died young and his father remarried, so he lived out of town all year round.

Lu Xuekun himself works as a seaman and is away for 10 months of the year. He only goes home during the Chinese New Year and stays for about two months, then goes to different ports to board ships.

The Lu family did not buy a house in the city. They built a five-story homestead in the village, with each floor measuring 120 square meters. There was only a small backyard, but it was uninhabited all year round.

In this case, “In order to collect criminal evidence and detect criminals, investigators may search the bodies, belongings, residences and other relevant places of criminal suspects and people who may hide criminals or criminal evidence, but not less than 2 people."

Among them, although a search warrant is required, in an emergency, a search can be carried out without a search warrant, including those who may carry a weapon with them; who may hide explosives, poisons and other dangerous items; who may conceal, destroy, or transfer criminal evidence ; possible hiding of other criminal suspects; other sudden emergencies.

In this case, there is "possible concealment, destruction, and transfer of criminal evidence." Of course, it is very possible for such a large case to have "other sudden emergencies."

Wu Junhao and his people arrived at the place, first found people from the village committee and asked them to be witnesses, and then opened the door of Lu Xuekun's house.

A motorcycle was parked on the first floor, looking clean.

Wu Junhao took photos, sent the pictures and videos to Jiang Yuan, and then went upstairs to check.

A village cadre followed and said with a smile: "There are fewer people living in the village now. Everyone has gone to work in the big cities. Lu Xuekun's family is in good condition in the village. He should make a lot of money as a seaman. There were still young people in the past." People follow me, and they can’t stand it anymore after getting on the boat once. Just Lu Xuekun, he has been working there for almost 10 years.”

"This person is an outdoor person." The police officer who accompanied him opened a room upstairs and saw that there were many kinds of outdoor clothes, equipment, shoes and other equipment inside.

"Seamen's income is higher than ours, and they can afford it." Wu Junhao curled his lips.

"He's still playing with drones." The police officer pointed out that there were indeed several drones in the transparent cabinet next to him.

"This thing costs a lot of money." The village cadre shook his head: "Young people nowadays don't save much money. I told them before to save a little, at least hundreds of thousands, so that they can pay a betrothal gift and find a wife. . He also said no, so I said..."

At this time, the cell phone rang.

Wu Junhao picked up.

I heard Jiang Yuan say from the other end: "It's the same car!"
