They came to the small restaurant opposite the criminal police team. The restaurant was not big, the food was very good, and the hygiene was good. While they were eating, two nurses from a nearby hospital came in, wearing white coats and no hats, with mask belts hanging on them.

On the ears, the mask is placed under the neck.

Huang Yiwei suddenly thought of something and told Cheng Liya before setting off: "Chengzi, let Dai Jiaxing bring a white coat, a mask and a hat."

Cheng Liya felt very strange: "The deduction site is not an autopsy, why are you bringing these things?"

Huang Yiwei just told her to bring it with her, maybe it would be useful. Cuijiayao Village is only 15 kilometers away from the county seat. There are not many cars at night, so she arrived quickly. Huang Yiwei looked up at the sky. Today is the 17th day of the first lunar month.

, there were floating clouds in the sky, and the moonlight was hazy, similar to the brightness of the moonlight on the day of the incident. The isolation zone at the scene was still there, so I crossed the isolation zone and walked into the supermarket.

Huang Yiwei asked Dai Jiaxing to put on a white coat, white hat and mask, and stand at the door of the supermarket leading to the small courtyard. He asked Pi Peng to pretend to be Huang Mao and flip through the drawer where the money was kept. After the two stood, Huang

Yiwei looked at Dai Jiaxing from Pi Peng's perspective, smiled knowingly, and said

Team Jian and Cheng Liya were asked to come over and take a look. Team Jian was very surprised after reading it. Due to the moonlight in the background, from Pi Peng's point of view, Dai Jiaxing's face could not be seen at all. He could only see a white coat, a mask and a white hat. This

It was the Bai Wuchang that Huang Mao saw. Huang Yiwei asked Peng Ying to take a photo.

According to the process described by Huang Mao, Dai Jiaxing said in a low voice: "Who are you?" Then Pi Peng followed Huang Mao's escape route and escaped from the door. This was the whole process of Huang Mao seeing the ghost.

Team Jian asked Huang Yiwei: "What Team Leader Huang means is that Huang Mao saw a man in a white coat and mistakenly thought it was a ghost. The other person at the scene, the man in a white coat, may be the real murderer."

.”

"Judging from the results of the on-site deduction, this is indeed the case. If our speculation is correct, then we need to find this person in a white coat." Huang Yiwei said, holding his shoulders.

Cheng Liya said: "People wearing white coats are usually medical workers, scientific researchers or workers in certain special industries. Of course, it is not ruled out that the murderer bought similar clothes to disguise himself."

While they were talking, Pi Peng walked back and forth on the escape route several times, and asked Dai Jiaxing to stand still and not move.

Dai Jiaxing stood and muttered: "I'm talking about biological and chemical weapons. You can't always use your power on me. Use your power on the murderer."

Pi Peng suddenly stopped at the place before going out. This place was closest to Dai Jiaxing, and he smelled it with his nose.

Pi Peng asked: "Do you smell anything?"

Dai Jiaxing said: "The hygiene in the supermarket is not good and it smells a bit moldy."

Peng Ying said: "The smell of pork on the meat table."

Captain Jian said: "It smells like celery."

Pi Peng turned to Cheng Liya: "Sister Chengzi, can you go out first?" Cheng Liya didn't understand a little, but she went out anyway.

Knowing that Pi Peng must have discovered something, Huang Yi walked to where Pi Peng was and asked, "Have you discovered anything?"

"Everyone stands in a different position, so the smell they smell is different." Pi Peng pointed to the ground under his feet, "Team Huang, what smell can you smell in this position?"

Huang Yiwei looked around. The nearby shelves were filled with drinks and instant noodles. They were all tightly packed, so it was impossible to leak the smell. Suddenly, Huang Yiwei smelled a familiar smell: "It's from the bird."

smell."

Pi Peng said: "Yes, that's the smell."

Dai Jiaxing said: "That's right, I'm a forensic doctor, but I wash myself carefully every day. I don't have the smell of corpses on my body."

Pi Peng waved his hand and said, "Jia Que'er, can you stop talking?" Dai Jiaxing wanted to say something else, but when he saw Huang Yiwei's eyes, he immediately shut up angrily.

Huang Yiwei looked at Pi Peng and said, "You mean this smell is unique to Dai Jiaxing."

Pi Peng said: "Actually, Sister Chengzi has a similar smell, which is a professional smell." Huang Yiwei nodded. Pi Peng continued: "If the murderer also has this professional smell, Huang Mao will

Don’t you smell anything?”

Dai Jiaxing retorted: "He is so panicked that he can even see people as ghosts. How can he still smell it?"

Pi Peng ignored Dai Jiaxing and continued: "I ignored the smell at the beginning of the Tianyang University case, and it later became important evidence. Of course, I just mentioned a possibility, and it may not necessarily exist."

Cheng Liya spoke at the door: "Jiaxing, you are an excellent forensic doctor. Don't we also make some judgments based on the smell of the corpse? The smell is of course important evidence." Dai Jiaxing stopped talking.

Huang Yiwei patted Pi Peng on the shoulder and expressed his approval. Peng Ying also finished taking the photos. Huang Yiwei exchanged a few words with Team Jian. They, a group of people and two cars, returned to Pingbei County. It was getting late, Team Jian

They each went home, and Huang Yi returned to the hotel for them.

Huang Mao was interrogated again the next day, and Captain Jian reminded him to think carefully about the details of the so-called ghost he saw. However, Huang Mao just ran away and could not remember any details at all. Huang Yiwei participated in the interrogation, and on the TV screen

A ghost image of the live demonstration was played.

Huang Mao saw it and immediately screamed, "Yes, yes, that's Bai Wuchang."

Huang Yiwei said calmly: "This is not the one you saw, this is what we went to the scene to restore. This white shadow was played by our colleagues, but the one you saw may have been formed in this way."

Huang Mao was stunned: "What on earth is going on?"

Huang Yiwei slowly explained: "First of all, this is not a ghost, let alone some black and white impermanence. This is a person, a person wearing a white coat."

Huang Mao understood and was very angry: "He must be sick. Wearing a white coat at night is scary."

"Think carefully about whether you saw anything, heard anything, or smelled anything. This will help eliminate the suspicion that you set fire to murder." Huang Yiwei reminded him.

Huang Mao calmed down, thought for a while, and said, "I seem to smell something."

"What does it smell like?" Captain Jian asked anxiously.

Huang Mao thought about it carefully and said, "It smells a bit like Chinese medicine. Yes, it tastes like Chinese medicine." Huang Yiwei reminded him again to think about it, but Huang Mao couldn't think of anything.

At the case analysis meeting, Captain Jian suggested that the murderer smelled of Chinese medicine, which reminded him of the clinic doctor he had investigated. It was he who sold penicillin to Hou Xiaocui, and his clinic had a strong smell of Chinese medicine. If he was the murderer

, then what was his motive for killing? Going to the clinic to inquire directly would probably alert the enemy. At this time, Captain Jian thought of a person, Huang Mao He Jinping.

Team Jian interrogated Huang Mao again, and after listening to Huang Mao's account, Team Jian felt confident. Huang Mao said that the doctor at the clinic is called Li Zhizhong, who is 42 years old. His feud with Ge Erhu began at the scene of the crime.

The homestead was originally a vegetable field, half of which belonged to Lao Ge's family and half to Lao Li's family. There used to be a very short edge in the middle of the vegetable field to distinguish the two families' fields. Later, when Lao Ge plowed the land every year,

They will secretly plow the edge of the ground, and then

Then a new land was built. In this way, after a few years, Lao Li's land was occupied and only about half of the original land was left. Lao Li went to Lao Ge to argue, but was beaten up by Dahu and Erhu.

After that, Lao Li became lame and was disabled for life. Later, Lao Li did not want to have another conflict over the land, so he voluntarily gave up the ownership. Since then, the land was completely occupied by Lao Ge. Later, when the village unanimously approved the homestead site, Lao Li

Ge built his current house.

It can be seen that Li Zhizhong was probably avenging his father, which was his motive for committing the crime, but why did he wait nearly twenty years before taking action? There must have been something that prompted him to make his decision.

Huang Yiwei sorted out the fragmented clues in his mind and told Captain Jian: "Hou Xiaocui was forced into prostitution by Ge Erhu and became murderous. He bought penicillin and killed Ge Erhu. Huang Mao couldn't bear to be bullied by Ge Erhu in every possible way.

So he went to the supermarket to steal. Among the two, only Hou Xiaocui and Li Zhizhong had an intersection. Hou Xiaocui's abnormal purchase of penicillin may arouse Li Zhizhong's suspicion. Li Zhizhong may have noticed that Hou Xiaocui wanted to use penicillin to kill people."

Huang Yiwei thought for a while and said: "Li Zhizhong knew that penicillin was a prescription drug and could kill people if used improperly. Why would he easily sell it to Hou Xiaocui? Is it possible that Li Zhizhong intentionally sold penicillin to Hou Xiaocui? He has been treating villagers all year round. He

Does he also know that Ge Erhu is allergic to penicillin? In addition, is it possible that he went to the scene to see his work after borrowing a knife to kill someone? He might confirm whether Ge Erhu was really dead. Can we inquire from these angles?

"

Captain Jian was very appreciative: "Old Huang, you are amazing."

Huang Yiwei said seriously: "Captain Jian, everything is still speculation. From the perspective of criminal psychology, many suspects will return to the scene. In addition to implementing the above possibilities, we also need to go to Li Zhizhong's clinic to search for evidence.

For example, the white coat, mask and hat worn at the crime scene, cotton gloves stained with gasoline, and

Huang Mao lost the key at the scene. I suggest you apply for a search warrant and send two people to go with us to search Li Zhizhong's clinic. You are responsible for interrogating Hou Xiaocui and asking her to recall all the details of her recent contact with Li Zhizhong. Xiang Gelan or

Hou Xiaocui confirms whether Li Zhizhong knows that Ge Erhu is allergic to penicillin."

A survey vehicle and a police car drove to Cuijiayao Village. Li Zhizhong was surprised when he saw the police. Huang Yiwei expressed his intention and showed him a search warrant. Li Zhizhong was a little nervous, but he had no choice but to let Huang Yiwei

Went in for them.

There was a strong smell of Chinese medicine in the clinic, and a machine for brewing Chinese medicine was running by the window. There was a white coat and a doctor's hat on the clothes hook. Pi Peng picked up the clothes and smelled them, and found that they were soaked in Chinese medicine.

There is also a faint fragrance, which may be the smell of detergent, and the clothes may have just been washed, which is very detrimental to evidence collection. There is a stethoscope, prescription paper and other items on the table. There is a

Medical trash can.

Dai Jiaxing laid out the garbage in the trash can one by one and placed it on the ground. After digging out all the garbage, he finally found a key at the bottom of the barrel. This was a key that had been changed privately with a file. It should not have been used.

It was equipped with a machine, but was filed manually. Dai Jiaxing asked Pi Peng to try the lock taken from the crime scene. The key didn't seem to fit very well, but after moving it up and down a few times, the lock finally opened.

In addition, no other physical evidence was found.

Outside the clinic, villagers gathered around to watch the excitement. Li Zhizhong looked a little confused and shouted: "You raided my clinic like this and seriously damaged my reputation. Who dares to come to my place for medical treatment? How can I help the world in the future?"

?”

Dai Jiaxing walked out of the door and waved the key in the evidence bag: "Let's not talk about the hanging pot to save the world. First, please tell us why the key in the trash can in your clinic can open the lock of Ge Erhu's house."

Li Zhizhong was immediately speechless, and there was a commotion in the crowd.

Pi Peng asked him: "Are you wearing these shoes these days?" Li Zhizhong nodded.

"Please change a pair of shoes." Pi Peng threw a pair of slippers at his feet, and he reluctantly put them on. Pi Peng picked up his shoes, looked at the soles, and used a large evidence bag to

After packing their shoes, the group took Li Zhizhong on their way back to the county criminal police team.

Returning to the criminal police team, Captain Jian also had good news. Ge Lan confirmed that their whole family had headaches and fever, and they basically went to Li Zhizhong’s clinic for medical treatment or medicine. In addition, Ge Erhu had seen a doctor at Li Zhizhong’s clinic last time when he was severely allergic to penicillin.

, it was Li Zhizhong who recommended that Ge Erhu be sent to the county hospital, so he had long known that Ge Erhu was allergic to penicillin. Team Jian showed Huang Yiwei Hou Xiaocui’s interrogation transcript.

Question: When you went to Li Zhizhong Clinic to buy medicine recently, did you mention that you and Ge Erhu both had colds?

Answer: I said it.

Question: You usually buy roxithromycin, but this time you bought penicillin instead. Did Li Zhizhong ask why?

Answer: He asked.

Q: How do you explain it?

Answer: I said that I had a severe cold and penicillin was more effective. He told me that Erhu was allergic to penicillin and could not give it to Erhu. He asked if he should buy other medicine for Erhu. I said
