Chapter 439: Rough Speculation

Hou Lejia felt that his head had just touched the sofa and he had just closed his eyes to take a nap, but he was awakened by the ringing of the phone.

He looked at the time again and it was really just after he closed his eyes.

He wanted to curse, but the caller ID showed that it was Jiang Yuan. Hou Lejia could only put away his emotions. After answering the call, he asked worriedly: "Forensic doctor Jiang. How is it? Nothing happened."

Who wouldn't be afraid of receiving a call from a forensic doctor in the middle of the day?

Jiang Yuan said: "I just heard that a criminal was arrested? Was it matched by sweat stains?"

"Yes. He came back from another place, his name is Du Jinfu. He thinks about making a fortune all day long, a blind drifter. Whether he can make a fortune or not, he hasn't figured out what's going on in these years..." Hou Lejia hadn't slept for more than a day, and was woken up just after falling asleep. He was a bit irritable.

Jiang Yuan said: "From the male corpse No. 1, the murderer was very strong and used a sharp blade to smash the lumbar vertebrae. The person you just arrested may not be of the same age. Unless he has undergone high-intensity training."

Hou Lejia was stunned and subconsciously said: "Did you catch the wrong person?"

"If the DNA is consistent, then the right person was caught. This means that there is more than one murderer." Jiang Yuan used the logical analysis of No. 1 to Hou Lejia.

Hou Lejia slowly sat up on the sofa: "During the interrogation, I asked him if he had an accomplice... He didn't reveal anything at all. Don't tell me, he has learned something over the years. I didn't see that he helped others cover up."

Hou Lejia must have been watching the robbery and murder case with two deaths throughout the process. During the interrogation, the criminal did not behave like he had an accomplice, and his age and identity all met the preset template of an old criminal, so the interrogators did not dig deeper into this aspect.

On the other hand, ordinary people who take the blame for others either show great righteousness or great justice. In short, there must be some spiritual core in it.

Hou Lejia did not see these things in the eyes of the murderer.

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

Jiang Yuan talked about bloodstain analysis again, and then said: "I just saw them looking for the murder weapon. If they can find it, protect the scene, especially the surrounding area of ​​the scene, to see if there are any footprints."

Hou Lejia thought he didn't need to worry about the first half of the sentence, but he became nervous when he heard the second half.

Yes, so many footprints were taken at the scene, and Jiang Yuan was a famous footprint master in the province.

Hou Lejia hurriedly said: "I will call them right away. Are you going to the scene now?"

"Yes. Also, check the interpersonal relationship of the criminal." Jiang Yuan ended the call, called Mu Zhiyang and Wang Zhong, and drove out slowly.

Hou Lejia was completely awake, 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 bring it back properly. They would also take photos and collect evidence in the process. But if you want to pay attention to the footprints under your feet, this is not easy.

Longli County does not have a trace inspection that can do footprints. Therefore, in the cases handled over the years, footprints were also collected, but they were never very caring or serious.

Hou Lejia was really afraid that his men would mess up the footprints.

…

Return to Changxin Village.

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

When Jiang Yuan arrived, Hou Xiaoyong and others had already found the murder weapon, but because of Hou Lejia's phone call, a group of people only took photos to collect evidence, and then pulled up a warning strip dozens of meters away, and climbed two people on the hill to prevent people from coming down again.

The latter is unnecessary, but the previous steps are still meaningful. Because a murder case had just happened in Changxin Village, the villagers were afraid when they saw the police, and then they were curious and watched. If there was no cordon, 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 small hill.

From the cement road to the small hill, it is a small fork in the road. Judging from the behavior of the criminals, they probably saw a small hill with relatively dense vegetation when they were leaving the village, so they turned in, used a hatchet to randomly cut a piece of land in the grass on the side of the road, and then dug a pit at a height of half a person, and then buried the hatchet in it, padding it with padding, and stuffed it with branches and leaves that had just been cut.

In this way, Du Jinfu and other criminals don’t have to spend much time and energy, and they don’t have to carry the murder weapon to show off in the city.

If a large-scale search is carried out by manpower, there is a high probability that it can be found. If a police dog is sent out of the village to look for it, it is also possible to find it.

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 one or two days, or after a rain, the situation will be completely different. The hatchet buried there may not appear again for ten or eight years.

If it reappears because of the collapse of the hillside or the road is repaired, it will most likely not flow back to the police, but will invalidate the chain of evidence.

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

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

Hou Xiaoyong and others were reminded and did not step on the mess. Jiang Yuan asked Wang Zhong to take pictures and take footprints on the spot, and recalled: "The sole of this sports shoe has also appeared at the murder scene. Now it seems that there should be major suspicion."

He motioned Wang Zhong to take pictures, and he took out the pad and brushed it, but still did not find the same sole.

For LV3's footprint analysis, the footprint itself is enough, but if you want to accurately identify the model from the vast number of 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, curiously asking: "You can 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 from 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 has three brothers and sisters, including two sisters. They have three boys and two girls in total. 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!" Hou Lejia 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 it should be about the same for two men." 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.”
