Solving the case: Combining the police dog's olfactory genes at the beginning

Chapter 29 The murder weapon is found (please collect and vote for me)
After the discussion, Zhao Dong made the final summary.

There are two possibilities for the murderer's motive. One is a temporary passion homicide, and the murderer is most likely an unemployed young man in society; the other is a premeditated vendetta.

Secondly, judging from the situation at the scene, there should be more than one murderer. Judging from the shoe prints left at the scene, one of them should be between 172-175 in height.

Subsequently, Zhao Donglai formulated corresponding investigation directions for these two different motives for committing crimes.

The first is to investigate the circle around the deceased to see if the deceased had any grudges or conflicts of interest with others during his lifetime.

Secondly, let the people of the technical squadron work overtime. The first is to test whether DNA can be extracted from the items collected today. If the DNA can be extracted, it can be compared in the DNA library; the second is to check the fingerprints collected today. Compare to see if there is matching DNA in the fingerprint library.

As for the other criminal police members, they continue to search Walnut Mountain because the most important murder weapon has not yet been found. Zhao Donglai feels that the murder weapon should still be on Walnut Mountain.

At around ten o'clock in the evening, Luo Fei received a notice from Zhou Weimin in the group. Everyone at the police station, except those on duty, would have breakfast in the police station cafeteria at 06:30 the next morning and set off for Walnut Hill on time at seven o'clock.

Luo Fei arrived at the police station around [-]:[-] in the morning. Director Zhou Weimin and Zhang Haiyang were already having breakfast in the cafeteria.

Luo Fei ordered a bowl of porridge, three steamed buns, and a plate of kimchi at the cafeteria window.Zhou Weimin waved to Luo Fei and motioned for Luo Fei to come over and sit down. Luo Fei came over with steamed buns and porridge and sat next to his master Zhang Haiyang.

"Only three steamed buns? Luo Fei, you don't have enough appetite! Your master and I can eat seven or eight steamed buns at your age. Young people should eat more. When you are my age, you will not be able to eat more. I can’t even eat anymore." Zhou Weimin said to Luo Fei with a smile, looking as kind as possible.

Zhang Haiyang, who was next to him, continued: "Zhou Suo, can it be the same now as it was back then? If we could eat enough at that time, everything would be fine, and there was no oil or water in our stomachs, so how could we not eat too much? I remember that I The most I ate was ten bowls of noodles in one sitting, which is incredible when I think about it now.”

"Yes." Zhou Weimin also nodded. Then Zhou Weimin looked at Luo Fei and ordered: "Luo Fei, after you finish your breakfast later, go make thirty buns and put them on the car. Searching on the mountain today is a physical job. Don't wait till then." Everyone is so hungry that they faint."

"Okay, Zhou Suo." Luo Fei nodded.

After dinner, Luo Fei went to make steamed buns, 30 steamed buns and a large bowl of kimchi.

At seven o'clock, the mountain search team from the Songxi Town Police Station officially set out to search the mountain.

I arrived at the crime scene at eight o'clock, thinking I was early enough, but I didn't expect people from the criminal police team to arrive earlier.

The criminal police team was led by Zhao Donglai, but compared to yesterday, there were fewer people from the criminal police team today. At least Luo Fei didn't see Yang Mei and Wu Xiaoyue.

I just said hello briefly and started searching the mountains according to the area designated by everyone.

Searching mountains is an irritating and boring physical activity, and although there is no sun in the morning, the air is very hot. It doesn't take long for everyone to start sweating profusely.

By ten o'clock in the morning, when the sun fully shines into the mountain, the temperature on the mountain becomes even hotter.

Luo Fei noticed that several old colleagues in the institute had already started paddling, and from time to time they ran to the shade of a tree to enjoy the shade. The time spent enjoying the shade was obviously getting longer as time went by, and they simply sat down at the back.

By about [-] o'clock at noon, the members of the search team seemed to be very lax in both actions and attitudes, especially the policemen at the police station. The members of the criminal police team were relatively better.

Luo Fei didn't care about this. He just focused on doing his own thing. From beginning to end, Luo Fei was probably the most serious and careful searcher on the scene.

"Uh." When Luo Fei pushed aside the bushes in front of him, a fishy smell suddenly drifted over. Guessing that it was probably the murder weapon, Luo Fei showed a look of joy in his eyes.

Luo Fei stepped over the bushes and carefully sensed the fishy smell in the air. He quickly determined the direction from which the smell was coming, which was coming from the direction of Wu Wei on the left.

Luo Fei chased him for more than 20 meters, and finally found the source of the stench in a bush - a big rusty wrench.The big wrench was obviously hidden in the bushes, and there were dried blood stains on it. It was obvious that this wrench should be the murder weapon used by the suspect.

"Zhou Suo, I found the murder weapon." Luo Fei shouted towards Zhou Weimin, who was not very far away from him.

Luo Fei's voice spread in the hot air. Everyone who seemed listless just now heard Luo Fei's words and instantly came back to life with full blood.

Zhou Weimin had already trotted over after hearing Luo Fei's words.

Zhao Donglai also got the news immediately and rushed over immediately.

"Looking at the blood stains on it, it's still new. It's probably the murder weapon. The criminal suspect probably used this wrench to give the deceased a fatal blow." Zhao Donglai's serious face showed a long-lost smile. Finding the murder weapon means that he is closer to solving the case. One step further.

Zhao Donglai then asked the criminal police team to put away the murder weapon. After returning, he immediately sent it to the technical squadron for inspection to see if the blood stains on it belonged to the victim.

The murder weapon was found and the search team withdrew.

Luo Fei and the others returned to the police station around two o'clock. Considering that everyone had worked hard all day, Zhou Weimin asked everyone to go home. He did not tell everyone to get off work at five o'clock. Zhou Weimin was very considerate of his subordinates.

When Luo Fei returned home, Wu Yan was the only one at home. Luo Hao and Luo Xiaoxiao went to play somewhere and haven't come back yet.

Luo Fei had something to eat and went back to his room to rest.

Woke up at 03:30.

"Luo Fei, if you are fine later, send the sauerkraut I pickled to your second aunt and uncle's house." Wu Yan said to Luo Fei.

"Okay, I'll take a shower and send the sauerkraut over."

Luo Fei nodded in response. Wu Yan pickled several jars of pickled vegetables every year and gave some to her second aunt and uncle's house. This was done every year. Perhaps Wu Yan used this way to thank Wu Xiaohui and Wu Zhiwei for their help to the family.

After washing up casually, Luo Fei took two cans of sauerkraut pickled by Wu Yan and set off.

The second aunt's house lived relatively close, so Luo Fei went to the second aunt's house first, but both the second aunt and the second uncle went to work, so the second aunt's high school daughter was doing her homework at home. Luo Fei left the sauerkraut behind and left.

His uncle's house lived a bit far away, so Luo Fei took a taxi there.

When Luo Fei got off the car at the small fork in the road, he happened to see his uncle's son, Luo Fei's eldest cousin Wu Yu, talking to a boy with a rooster head at the fork in the road.

In Luo Fei's impression, he didn't seem to have a very good relationship with his eldest cousin. Both parties looked down on each other. After Wu Zhiwei and his wife made a big deal because of borrowing money, Wu Yu seemed to have never been to Luo Fei's house again.

"Cousin, are uncle and the others at home?" Luo Fei walked over and asked.

Wu Yu glanced at Luo Fei, then looked at the jar in Luo Fei's hand, and then started talking to the boy with the rooster head next to him, obviously unwilling to talk to Luo Fei.

Luo Fei didn't mind either. If it weren't for Wu Zhiwei's face, he wouldn't bother to talk to Wu Yu.

Just when Luo Fei was about to walk towards the house, Luo Fei suddenly felt a familiar smell. This smell was the same as one of the smells smelled at the murder scene of Tang Quanquan.
