National Forensic Doctor

, update the latest chapters as soon as possible!

Hou Lejia felt that his head had just touched the sofa, and he had just closed his eyes and wanted to squint for a while, when he was woken up by the ringing of the phone.

Looking at the time again, I really just closed my eyes.

He wanted to curse something, but the caller ID was from Jiang Yuan. The Hou Le family could only put away their emotions. After the call was answered, they asked a little worriedly: "Forensic Doctor Jiang. How is it? Nothing happened."

At noon, I received a call from the forensic doctor. Who wouldn't be afraid to leave him alone?

Jiang Yuandao: "I just heard that a prisoner was captured? Was it matched through sweat stains?"

"Yes. His name is Du Jinfu, who came back from other places. He thinks about making a fortune all day long, and blindly makes money. Whether he can make a fortune, he hasn't figured out how in these years..." The Hou Le family didn't sleep for more than a day, and they just fell asleep. Being woken up makes me somewhat temperamental.

Jiang Yuandao: "Judging from the body of male No. 1, the murderer was very strong and chopped the lumbar vertebrae into pieces with a sharp blade. Judging from the age of the person you just arrested, I'm afraid he does not qualify. Unless he has undergone high-intensity violence Trained.”

The Hou Le family was stunned and said subconsciously: "Did you arrest the wrong person?"

"If the DNA is consistent, the wrong person has been arrested. It means there is more than one murderer." Jiang Yuan used 1's logical analysis to Hou Le's family.

Hou Lejia slowly sat up straight on the sofa: "During the interrogation, I asked him if he had any accomplices... They didn't reveal anything at all. Don't tell me, he has learned something over the years, but I didn't even notice that he had accomplices." Cover up."

The Hou Le family must have been watching the entire robbery and murder in which two people died. During the interrogation, the prisoner did not act like he had accomplices, and his age and identity fit the preset template of an old prisoner, so the interrogators did not dig deeper into this aspect.

On the other hand, when ordinary people take the blame for someone else, they either act righteously or with awe-inspiring righteousness. In short, they must have some spiritual core in them.

The Hou Le family did not see these things in the eyes of this murderer.

"Is there any evidence?" Hou Lejia asked again.

Jiang Yuan talked about what he learned about blood stain analysis, and then said: "I just saw them looking for the murder weapon. If they can find it, protect the scene, especially around the scene, to see if there are any footprints."

After hearing the first half of the sentence, Hou Lejia thought there was nothing to worry about, but when he heard the second half, he became nervous.

Yes, so many footprints were collected on site, and Jiang Yuan is a famous footprint master in the province.

Hou Lejia said hurriedly: "I'll call them right away. Will you go to the scene now?"

"Go. Also, check the prisoner's interpersonal relationship." Jiang Yuan ended the call, called Mu Zhiyang and Wang Zhong, and drove out slowly.

The Hou Le family was completely sleepless, and various orders were issued quickly.

He knew the ability and style of his own police officers. For example, Hou Xiaoyong and others who went to retrieve the murder weapon would definitely get the weapon back, and the steps in the process, such as taking photos and collecting evidence, would be done well. But if you want to pay attention to the footprints under your feet, this is not easy.

Longli County itself did not conduct trace inspection of footprints. Therefore, the eucalyptus I have made over the years has left a lot of footprints, but I have never been too concerned or serious about it.

The Hou Le family was really afraid that their men would mess up their footprints.

…

Return to Changxin Village.

The murder weapon was buried on a hillside outside the village entrance.

When Jiang Yuan arrived, Hou Xiaoyong and others had already found the murder weapon, but because of Hou Le's family's phone number, a group of people only took photos to collect evidence, then pulled up warning strips dozens of meters away, and climbed two feet above the hill. Individuals, lest people come down again.

The latter is not necessary, but the previous steps are still meaningful. Because of the murder that had just occurred in Changxin Village, when the villagers saw the police, they were first afraid, and then curious and watched. If there were no warning tape, they would have to break in now.

Jiang Yuan, Mu Zhiyang and others parked the car on the cement road of the village road and walked to the hillside.

From the cement road to the hillside, there is a small fork in the road. Judging from the behavior of the prisoners, they probably saw a long and fairly dense hill here when they left the village, so they turned in. Use a hatchet to randomly cut out a place in the grass on the side of the road, then dig a hole at half a person's height, and then bury the hatchet in it, laying it on top with the branches and leaves you just cut down. All stuffed too.

By doing this, Du Jinfu and other criminals wouldn't have to spend much time and energy, and they wouldn't have to carry the murder weapon around in public.

If a large-scale manpower search is used, there is a high probability that it can be discovered. If police dogs are sent out of the village to look for it, it is also possible.

But as long as there is no large-scale search, or the scope and direction of the search are not on the road outside the village, then after a day or two, or if it rains, the situation will be completely different. It is possible that the hatchet is buried inside. Those buried for ten or eight years will never appear again.

If it reappears due to hillside collapse or road construction, it will probably not be returned to the police, but will invalidate the evidence chain.

However, the above are all things after the golden 72 hours.

Within 72 hours, there were still footprints on the ground from the cement road to the hillside.

Hou Xiaoyong and others were reminded that there was no chaos, so Jiang Yuan asked Wang Zhong to take pictures and take footprints on the spot, and recalled: "The sole of this sneaker has also appeared at the murder scene. Looking at it now, it should be Seriously doubtful."

He motioned to Wang Zhong to take a photo, took out his pad and swiped the photos, but still couldn't find the same sole.

For LV3's footprint analysis, the footprint itself is enough, but if you want to accurately identify the model from a vast sea of ​​over a million shoe soles, which sounds a bit cool, LV3 is not enough.

However, Jiang Yuan's words were already a bit magical to the ears of Hou Xiaoyong and others.

Hou Xiaoyong stood behind the warning tape and stretched his neck, and asked curiously: "Can you tell you are wearing sneakers?"

"Judging the type of shoes based on the footprints is the basis." Jiang Yuan handed the pad back to Mu Zhiyang and said at the same time: "The degree of dispersion of the tread radius is different. The degree of dispersion of sports shoes is higher than that of flat shoes, leather shoes and cloth shoes, but As for the specific coefficient, it would be easier if we could find the exact type of shoes, but now I can only make some rough guesses..."

Jiang Yuan walked slowly along the dirt road, looking at him as he walked: "The fellow prisoner is about 28 years old, 175 centimeters tall, and fat..."

The criminal police officers of Longli County were listening.

The policeman at the local police station looked suspicious and asked Hou Xiaoyong in a low voice: "A rough guess?"

Hou Xiaoyong laughed.

The policeman said: "If it's so accurate, just check the identity cards of the criminal's relatives."

Upon hearing this, Hou Xiaoyong felt that what he said made sense, so he took out his mobile phone and began to check the ID cards one by one along the lines of Du Jinfu's relatives.

He didn't look at anything else but age.

Hou Xiaoyong looked at them one by one. Du Jinfu has long been divorced. His two children, both in their early 20s, lived with their mother. Du Jinfu himself has three brothers and sisters, including two sisters. He has a total of three boys and two girls. Among them, the eldest son of the eldest sister, Sun Jinqiang, happens to be 28 years old...

Although it was said that Du Jinfu had other relatives or non-relatives, after seeing this, Hou Xiaoyong couldn't help but report it to the captain Hou Lejia.

"Bring them back and ask!" The Hou Le family made the decision without hesitation, and reminded: "Bring a few more people with you. If it is the murderer, he will cut off the person's lumbar spine with one knife."

Hou Xiaoyong took it seriously and said, "I'll go get some electric batons."

Hou Lejia then showed Sun Jinqiang's identity information to Jiang Yuan, and paying attention to Jiang Yuan's expression, he said, "It should be two people doing it. There won't be a third person, right?"

"Look, there are two people hiding the murder weapon here. They came on motorcycles, and two men should be enough." Jiang Yuan gave a brief analysis.

"That's good, that's good." Hou Le's family felt a little unconfident, and gritted their teeth and said: "When I bring this guy back, I'll have someone examine him carefully. There is an uncle who helps his nephew carry the bag, so I'd like to Let’s see if any nephew is willing to carry the bag for his uncle.”
