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

When Luo Fei thought of this idea just now, he was a little shocked. How could someone kill people just for their reproductive organs? However, according to speculation, this possibility is the highest.

"No way, how could there be such a perverted person who kills people and mutilates their genitals?" Wang Lei felt a chill in his lower body after listening to Luo Fei's words.

"Perhaps the reproductive organs were taken away by wild cats and dogs?" Wang Dong, the leader of the third team, said doubtfully.

"Okay, does anyone else have anything to add? No more? Okay, as for the murderer's motive, one possibility is a vendetta caused by emotional entanglements, and the second possibility is killing specifically for reproductive organs." Zhao Donglai recorded.

In the following time, Zhao Donglai asked several questions one after another.

Later, Zhao Donglai arranged the task.

A group is responsible for investigating the deceased's movements yesterday to find out where the deceased went all day yesterday. Who were you with and what did you do? When I came back in the evening, I came back alone or with someone.

The second team is responsible for investigating the personal life and relationships of the deceased to see if the deceased had any conflicts with others, or did the deceased have any emotional problems?

The third group is responsible for investigating people in the vicinity to see if they have seen the deceased last night, or if they have seen strangers entering and exiting the Jiuli River.

After receiving the assignment, each group started working.

"Luo Fei, your nose is so good. Based on the smell of the deceased, can you track where the deceased went?" Yang Su asked.

He had also heard about the fact that Luo Fei had a good nose. During Su Xiao's previous case, Luo Fei smelled the smell of smoke in the room, thus confirming that Su Xiao committed suicide instead of suicide.

"There should be no problem." Luo Fei replied confidently. As long as the target person's scent is still there within 24 hours, Luo Fei can track it through scent.

"Very good. This will make our investigation much easier." Yang Su said with a smile.

"Luo Fei, your nose is so sharp? Are you sure you're not a humanoid police dog?" Xia Zheng looked stunned when he heard this.

"What are you talking about!" Yang Su glared at Xia Zheng after hearing this.

"Can you speak? You're a guy with low EQ. With your brain and EQ, you don't know how you got in. To be honest, did you go through the back door in the first place?" Wang Lei asked disdainfully.

Luo Fei didn't care, he was too lazy to care about such trivial matters.

Luo Fei then came to Jiulihe Street by following the scent left by the deceased.

But when they arrived at Jiulihe Street, Luo Fei found that there was the smell of the deceased in many directions. It was probably because the deceased wandered around the street during the day, causing the street to be filled with the smell of the deceased.

Luo Fei randomly locked in a direction, and then followed the smell to a mahjong parlor next to Jiulihe Street. The smell left by the deceased was the strongest here, which meant that the deceased had stayed here the longest, and the molecules in the deceased's body were here. spread the most.

The mahjong parlor is very small, with only enough space for two mahjong machines, but at this time there are many people in the mahjong parlor and it is also very noisy, mainly because there are so many people watching.

Luo Fei and the other five entered the mahjong parlor. Because they were not wearing police uniforms, they did not attract any attention.

"We are from the criminal police team. Who is the boss here?" Yang Su approached the mahjong table and asked seriously.

As Yang Su finished speaking, the scene that was noisy just now immediately became quiet.

"I am, I am." Among the onlookers, a lean-looking man quickly came over and answered.

"Comrade police, what do you want from me?" the lean man asked, with a somewhat respectful and flattering expression on his face.

"Do you know Zheng Bin?" Yang Su asked.

"We know him. He often comes here to play mahjong. Last night he was still playing mahjong here until ten o'clock! Who knew something would happen to him on his way back?" the mahjong parlor owner said with emotion.

When Yang Su asked the owner of the mahjong parlor, everyone else in the mahjong parlor was about to leave. After all, many people have the mentality that doing more is worse than doing less, let alone such a deadly thing.

"Don't leave yet. We are just asking about something. We will leave after asking." Luo Fei said, and then the man who was about to leave stopped.

"Yes, please cooperate with our work." Yang Su also looked at the people who were about to leave and said.

Yang Su then continued to ask the owner of the mahjong parlor, while Luo Fei, Xia Zheng, Wang Lei and Zhong Jun asked other people.

Twenty minutes later, Luo Fei and the other five finally finished asking and left the mahjong parlor.

According to the description of people at the mahjong parlor, Zheng Bin played mahjong until ten o'clock last night and left the mahjong parlor. He left alone without anyone else. Originally, a person at another table called Zheng Bin to wait for him. After he finished the fight, the two went back together, but Zheng Bin left without waiting for him.

"There's something wrong with the team leader." Luo Fei said suspiciously.

"What's wrong? What's wrong?" Yang Su looked at Luo Fei doubtfully.

Luo Fei thought for a while and said: "How long did it take us to follow from the crime scene to here? Less than half an hour! Even if we walked slowly, it would not take an hour, but the forensic doctor determined that the time of death of the deceased was Last night around 12 o'clock, Zheng Bin left the mahjong parlor at 10 o'clock. I don't think it would take more than two hours to walk from here to the crime scene in the middle of the night."

"So I suspect that Zheng Bin must have gone somewhere before going home."

"Yes, it takes twenty minutes to get to the crime scene from here, but Zheng Bin took two full hours. This must be wrong." Yang Su's eyes suddenly lit up.

"Luo Fei, can you continue tracking?" Yang Su then looked at Luo Fei and asked.

"Okay, the road going up diagonally ahead also smells of the dead." Luo Fei replied.

Then Luo Fei took Yang Su and others and followed the road that went up.

After walking less than 400 meters, Luo Fei discovered that the smell of the deceased entered a two-story house next to the highway.

The first floor of the house is a shop. Inside the shop, a woman with an ordinary appearance but a very sexy figure is sitting behind the counter playing with her mobile phone. However, looking at the woman's solemn and absent-minded look, it is obvious that she has nothing on her mind at this time. on mobile.

"The smell of the deceased has entered inside." Luo Fei pointed to the house in front of him and said to Yang Su next to him.

Yang Su frowned and then walked into the store.

Because the woman was too distracted, Luo Fei walked in without noticing.

"Excuse me, did Zheng Bin come here last night?" Yang Su asked the woman, while Luo Fei took a few steps towards the inside of the shop. He found that the smell of the deceased entered the room inside the shop.

"What? I'm sorry, what did you say?" The woman woke up from her daze and asked nervously.

"We are from the criminal police team. Did Zheng Bin come here around ten o'clock last night?" Yang Su asked again.

The woman's face was obviously panicked, and then she pretended to be calm and said, "No, Zheng Bin hasn't been here before?"

Luo Fei next to him looked at the woman and said in a serious tone: "Madam, you should also know that Zheng Bin was killed last night and we are investigating the murderer. This matter is not a joke. If you knew In some cases, if you know about it and fail to report it, you will be held legally responsible if it is discovered."
