Song Xichen sighed and said, "Zhang Baowen, please tell me about your investigation."

Zhang Baowen said: "We have investigated the nearby residents, and there are no witnesses. The victim hardly interacts with the neighbors, and has almost never seen anyone else coming here to look for him. He usually does not go out during the day, nor does he cook.

When he's hungry, he orders takeout. He always goes out after ten o'clock in the evening and returns home at five or six in the morning. Some aunties who get up early to dance square dance say they often see him walking home from outside at five or six o'clock. So.

Neighbors speculated that he must have done something disgraceful.

People in that area said that he was very rude and would not say hello to his neighbors. When others greeted him, he would not say a word and would go his own way."

Sun Yuke said: "I followed the captain's instructions and took all-round photos and videos of the room where he lived. His room was very simple, with no pots and pans, only a bed, and not even a table.

There are also some simple toiletries. It doesn’t feel like home, it feels like a temporary hotel.”

Song Xichen asked: "Where are the electronic equipment?"

Sun Yuke replied: "There is nothing, not even an old TV or an old computer. The plugboard on the bedside only has a mobile phone charger, but I didn't find a mobile phone at home. I found a drug ticket from a pharmacy in the trash can.

I picked it up."

Meng Xiaofei said: "Captain, we led people to dig through the grass and trash cans in the nearby alleys. We didn't find the victim's cell phone or wallet or other belongings. There was nothing."

Liu Yiqiang said: "We checked the surveillance cameras nearby. Since the communities there are relatively old and belong to shantytowns, there are surveillance cameras, or few of them can be used. We found the surveillance cameras in several nearby shops.

He, however, is not the trace of yesterday's actions. He went to the drugstore the afternoon before yesterday and never went out again. There was no particularly suspicious person found, but at around 5 o'clock today, a man wearing a jacket was found.

In the video, this person often visited Calabash Alley during this period, but we asked some nearby residents and they all said they did not know this person."

As Liu Yiqiang spoke, he put the video clip of that person on the big screen.

Song Xichen took a look and said, "He is not a suspect."

Because the person in the video on the big screen was Detective Maori Shen who he had just visited, and he also took a cowhide file bag of information from him.

Zhang Baowen said at this time: "Captain, is this case difficult to investigate? It feels like there are no clues at all?"

Song Xichen said: "Yes, how come there are no clues? This victim has a criminal record, do you know? Do you know what the criminal record was for him?"

Why was Yan Haoshou arrested in that case? And why was he released so soon after he was arrested?"

At this time, everyone was even more surprised, almost dumbfounded by Song Xichen's magical power. How did the captain know that Yan Haoshou had a criminal record? Why didn't everyone consider this aspect?

Song Xichen then said sternly: "Since we can't find his mobile phone, is it possible that his mobile phone was taken away by the murderer? If there was a mobile phone, I also believe that many problems might be easily solved. But now there is no mobile phone.

Is there really nothing we can do? Can we find his mobile phone number based on his identity information, and can we use the mobile phone number of Yan Haoshou provided by his parents to find people who have close contact with him?

Is it possible to verify what software he uses and what he does?”

Everyone can't help but say that the leader is really awesome. He can quickly find a new breakthrough every time. He is like a lion who never admits defeat, always so high-spirited.

Song Xichen thought of what Mao Lishen said, saying that Yan Haoshou might be engaged in the sale of some kind of illegal drugs. If this is really confirmed, then they are probably one step closer to the truth. And it is consistent with Han Yijing's psychological judgment of the people at the scene. The victim may be

He was making a deal or something ulterior with the murderer, and it was expected that the incident would be short-lived because the victim was wearing pajamas and slippers.

He added: "Sun Yuke, take the invoice for buying medicine and go to the drugstore to verify it. Then ask the medicine seller if he often buys medicine there? What diseases do these medicines usually treat?"

Song Xichen once again assigned tasks to his men. He took a photo of the invoice for buying medicine, and then came to the forensic department.

Sure enough, Lao Jia was still looking at Yan Haoshou's body, and from time to time he seemed to be having in-depth soul communication with the body.

Song Xichen patted Lao Jia on the shoulder and said, "Old Jia, help me look at something."

He opened his phone and flipped through the drug purchase invoice he just took, then handed it to Lao Jia.

Lao Jia took a look and said: "Whose medicine do you have? It belongs to the person lying down?"

Song Xichen nodded.

Lao Jia pondered and said, "That shouldn't be the case. Two of these drugs are used to treat insomnia, and the other two are pain-relieving drugs. However, taking them in large amounts can have an anesthetic effect, and in severe cases, they may even cause hallucinations."

Song Xichen suddenly felt that something was wrong. Even if Yan Haoshou bought these medicines that could indeed stun women, other people could also buy them in pharmacies. Why should they buy them from him at a high price? This is obviously illogical.

He felt that he was about to make a major discovery, but now the major discovery was covered with a thick layer of fog, making it impossible for him to see clearly.

What's going on?

The purchase of medicine is definitely an important puzzle piece in this case, but where should it be placed? What role does it play in this case?

At this time, Liu Yiqiang called and said: "Boss, I have discovered something. I am now in the Technical Investigation Department."

Song Xichen said: "I'll be there soon, please wait a moment."

Song Xichen came to the Technical Investigation Department and saw Liu Yiqiang sitting in front of a computer, his fingers flying up and down on the keyboard. He sighed that it was indeed the director who directly recruited him from the university to this city's police station. Since the Internet is so developed now,

The preciousness of network technology is more vividly reflected. Controlling network information has increasingly become the key to solving crimes.

Liu Yiqiang called the captain to the chair next to him and said: "I found the mobile phone number under his identity information through the operator. Indeed, this mobile phone number is usually on 24 hours a day, but at 2:26 this morning

He turned off his phone at the time. Through the operator, I also found a few people he often talked to, and I also made a list."

Song Xichen gave Liu Yiqiang a thumbs up and praised: "Young man, you did a good job."

Liu Yiqiang said: "Captain, don't rush to praise me, I haven't finished speaking yet. This mobile phone number is not the mobile phone number of his son left to us by the victim's father. It belongs to the person in charge of the number that his father left to us.

The identity information shown is false. This person does not exist on the national information network or he died three years ago. Moreover, this mobile phone number is still displayed when the phone is turned on. According to the operator's positioning information, it is at Yan Haoshou's home.
