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

"It is very likely that it was left by the criminal suspect. Take everything on the ground back and see if you can extract new fingerprints or the suspect's DNA from it."

When Luo Fei and Zhang Haiyang arrived here, the first thing Luo Fei saw was the bones next to the fire. He felt suspicious in his heart. He originally wanted to pick up the bones and take a closer look, but he was afraid of damaging the scene, so he took no action. .

Just when she was about to alert her colleagues from the criminal police team, she saw Yang Mei next to her putting on gloves, squatting down, picking up a bone, frowning, identifying it carefully, then stood up, turned her head and looked at Zhao Donglai, "Zhao Donglai Team, this is a dog bone.”

"Dog bones?" Zhao Donglai frowned and made a guess in his mind.

"We have never seen the deceased's dog before. Could this be the deceased's dog?" Zhou Weimin asked in shock.

"It's not impossible." Zhao Donglai nodded and answered, then looked at everyone, "Let's search the surroundings carefully. If this dog bone is the victim's dog, then the suspect should have killed and disposed of the dog nearby. ."

After listening to Zhao Donglai's words, everyone began to search everywhere again.

Luo Fei saw Yang Mei and several people from the criminal police team collecting cigarette butts, and looked at the gloomy and humid weather, feeling a little depressed.

If it hadn't rained last night, Luo Fei would have been certain that he could track the suspects based on the smell they left on their cigarette butts. Unfortunately, the weather was not kind. It had not rained in Ningjiang County for a long time before this. It rained, but it happened to rain last night.

Just last night, Luo Fei was reading in the bedroom, listening to the sound of rain outside the window. Luo Fei was still very happy about the sudden and timely rain, but at this moment, Luo Fei just felt that the rain was really untimely.

Because of the rain, all the smell left by the suspect in the air has been washed away. It is obviously no longer realistic for Luo Fei to smell the smell left by the suspect in the air.

However, there was still a glimmer of hope in his heart, and Luo Fei walked over.

"Yang Mei, can I smell it?"

When he came to Yang Mei's side, Luo Fei asked. The criminal police team knew Yang Mei well. Luo Fei knew her better, so he could only ask Yang Mei.

Yang Mei glanced at Luo Fei and thought that Luo Fei had a good nose and knew what Luo Fei was thinking, so she handed Luo Fei the plastic bag with the cigarette butts in her hand, "It rained yesterday, and I want to track the suspect based on the smell." It’s probably unlikely that there will be any human traces.”

Luo Fei also knew it, but he had to give it a try anyway.

Luo Fei raised the plastic bag containing the cigarette butts to his nose and took a deep sniff.

In addition to the thick smell of smoke, Luo Fei smelled three different smells, which should come from three people, which means there are at least three suspects.

"How was it?" Yang Mei asked Luo Fei, but she didn't have any expectations in her heart.

"There are three different smells, they should come from three people." Luo Fei said and returned the cigarette bag in his hand to Yang Mei.

Yang Mei thought for a moment, "That means there are at least three suspects? Or even more."

"It should be." Luo Fei nodded in response, but his brows were deeply furrowed. Sure enough, he couldn't smell these three smells in the air.

"There should be no smell left by the suspect in the air!" Yang Mei asked, noticing Luo Fei's expression.

"Yeah" Luo Fei nodded. He had known that there would be such a result, so he was not particularly disappointed.

After confirming that there was really no smell of the suspect in the air, Luo Fei rejoined the search team. The scope of the search was slowly expanding. Not long after, two criminal police members found dog skin, After identifying the dog's internal organs and head, Tang Dayou confirmed that this was the dog owned by the victim Tang Quanquan.

After that, neither the criminal police team nor the police station received any useful clues.

At seven o'clock in the evening, it was completely dark and there was no way to continue the search, so we had to temporarily close the team.

It was already eight o'clock in the evening when Luo Fei and the others returned to the police station. At this time, everyone was tired and sleepy.

The police station cafeteria left food for everyone, but except for a few people who ate in the cafeteria, most of them chose to go home to eat.

Luo Fei also chose to go home to eat. He had eaten the food at the police station several times, but the taste was just average and not delicious. Unless he had no choice, Luo Fei would not eat in the police station cafeteria.

Wu Yan called Luo Fei at six o'clock. Luo Fei originally thought that it would be very late to go home, so he asked Wu Yan not to leave food for him, but Wu Yan said that she had made sweet and sour pork ribs today, so she still left it for him.

Wait for Luo Fei to get home.

"Xiaoxiao, your brother is back. Bring the food to your brother." Wu Yan, who was putting on a bracelet, urged Luo Xiaoxiao, who was watching TV.

Luo Xiaoxiao was lying on the sofa watching TV. When he heard Wu Yan's words, he jumped up and said, "Brother, I'm going to bring you food. Mom made sweet and sour pork ribs tonight, and they were delicious."

"Yes." Luo Fei smiled and nodded.

Compared with Luo Hao's laziness, Luo Xiaoxiao seems to be much more diligent and sensible. Therefore, Wu Yan usually likes to instruct Luo Xiaoxiao to do things much more often. Of course, Luo Fei himself will not spoil Luo Hao. Whenever he has the opportunity, He will ask Luo Hao to do things.

"Xiao Fei, how is your search going today? Have you found the murderer?" Wu Yan asked Luo Fei, who was eating, while wearing a bracelet.

Luo Fei picked up some unimportant places and told Wu Yan casually. Luo Xiaoxiao and Luo Hao were also listening with interest.

After finishing the meal, Luo Fei asked Luo Hao to clean up the dishes and table without waiting for Wu Yan to speak. This boy was so lazy that Wu Yan could not control him at all. Only Luo Fei could control him, or Wu Yan could control him when Luo Fei was around. Can be commanded.

At this time, the members of the Criminal Police Team had just finished eating, and the Captain of the Criminal Police Team, Zhao Donglai, asked everyone to go to the conference room for a meeting.

When everyone arrived, Zhao Donglai first asked everyone to summarize the investigation of the murder scene.

The next step is to analyze the case.

Members of the criminal police team expressed their opinions one by one. Basically everyone agreed that this was a temporary homicide. The reason for this belief was because of the fire and bottles of wine found near the crime scene.

Everyone speculated that the suspects were several young people from society who had the audacity to kill the deceased after drinking some alcohol.

However, some criminal police officers suspected that the fire, empty beer bottles, and cigarette butts were all deliberately disguised by the criminal suspect. The criminal suspect wanted to use this method to confuse the police and mislead the police's sight to conceal his true purpose.

They felt that the deceased suffered inhumane treatment before his death. This was a naked act of revenge. The murderer was taking revenge on the victim. Therefore, they felt that there should be a lot of hatred between the criminal suspect and the deceased.
