time-limited arrest

Qi Yi just came back from his field work and saw Yu Su just coming out of the forensic office.

"Brother Yu, did you find Fang Ye, man? He is asleep in the hotel now. He almost couldn't help laughing when he heard that his father died." Qi Yi sighed helplessly, thinking that Fang Pengsheng and Fang Ye had no father-son relationship, I didn't expect it to happen? I froze like this.

Yu Su recalled what Lin Huaiyue had told him in the early morning, and said to Qi Yi: "Consultant Lin learned from Boss Xue that the reason Fang Pengsheng divorced his ex-wife was because of cheating in marriage. I made this kind of The matter, the son? The son? is an adult, can't hide it, the relationship is of course? It's not much better? Go?."

Chen Yifan's stepmother has been taking care of him very closely, even so, Chen Yifan still doesn't appreciate it, let alone Fang Ye who learned about his father's cheating in marriage.

"Is there an alibi?" Yu Su asked.

Qi Yi nodded, "Yes, I've checked the monitoring, these days Fang Ye and his friends are in the bar at night, and they only go back to the hotel with my sister in the early hours of the morning. They don't come out during the day, and they continue to spend their days drinking at night. Originally, they wanted to bring him back to protect them. But he didn't want to go."

"Then? Send someone? Follow him. He has an alibi, but he has a motive to kill someone. It doesn't rule out the possibility of him buying|murder|killing|someone." After Yu Su finished speaking, he walked into the office.

He put the breakfast on the table and said to Lin Huaiyue, "I'm going out to work, do you remember after breakfast? Take your medicine."

Lin Huaiyue looked at Yu Su holding the helmet and was about to leave, and asked, "Where are you going? I'm much better, do you want to go with you?"

Yu Su frowned, looked at Lin Huaiyue, and joked: "I still feel sorry for you when you are sick, but seeing you are so clingy, why am I so lucky?"

"Who is attached to you? If you want a witness? It is beneficial for me to be there!" Lin Huaiyue said, took a sip of water from the water glass, avoiding Yu Su's eyes.

Yu Su chuckled, but did not agree with Lin Huaiyue to follow.No matter how short he is, he won't? Let a psychological consultant do the field work, running around in the wind and rain, and Lin Huaiyue is now a patient? It doesn't make sense.

"I applied for a transfer order from the Du Bureau. The file of Lu Lingling's death case will be sent to us soon? You can watch it for me." He said, reaching out to rub Lin Huaiyue's hair, "Besides, I really need you When the time comes, Team Yu, will I? Let go of this opportunity?"

Lin Huaiyue knocked off Yu Su's flailing hand, "Captain Yu, walk slowly!"

Now the knives are under control, and all shops that sell knives have a record in the police station.

Excluding the shops that only provide sales services, there are only three shops that can sharpen knives. Yu Su took the data provided by the forensic doctor and trace inspection and rushed to the knife sharpening shop.

The owner of the Knife Grinding Shop shook his head frequently looking at the photo Yu Su showed, and tried his best to choose a few knives as alternatives, "These are the knives usually used for cutting meat. Officer, you gave too little information, I I can't tell."

After inquiring about the two, the boss was helpless in the face of the photos.Yu Su took away a few knives recommended by the boss and the store's recent customer records for sharpening knives, and took samples of the iron filings left over from sharpening knives to take back. For comparison, he hurried to the last workshop.

This workshop was not originally a place to sell knives, but a blacksmith's shop, usually making some shovels and pots, and it was a place to transform ironware.

Now the number of people who use ironware is much less, so the workshop helps sharpen the knives. In order to prevent hidden dangers, the police station still records them in the system.

The blacksmith shop owner looked carefully at the knife marks in the photo, and sighed: "This knife is too sharp, there is no room left."

Even for chefs and butchers, the sharper their knives are, the better. If you can't hold back your hand, you will be the one who gets hurt, so you have to leave yourself some way out.

They sell knives with iron, and they generally don't ask customers to buy such a sharp knife. Sooner or later, something will happen.

This blacksmith shop has been around for nearly forty years, and the owner is very experienced. Yu Su looked at the knife marks on the photo, and then asked: "Then, do you sell such a knife here?"

The boss thought for a while, then nodded and said, "Yes, there is. A few days ago, a man came over to make a custom order. He didn't ask for anything. He didn't mention it, so he should act quickly."

Will it be chefs who specialize in custom-made knives, or people who are very particular about knives? Everyone? has their own habits.

They are iron-clad, and they do what the customers want? That's right, but the customer just mentioned? It's so strange, he thought he must be a novice butcher.

The boss looked at the policeman in front of him, and finally came back to his senses, "No?...No? Something happened to that knife!"

Yu Su nodded, "Did the police suspect that the murderer had gone to a knife sharpening shop before committing the crime? As you said just now, your shop recently sold similar knives."

The boss was so frightened that his whole body turned cold, and he quickly defended himself to the policeman in front of him, "Knife... the policeman, this matter? It has nothing to do with me, I also followed the customer's request!"

Yu Su took some iron filings from the side of the lathe, and asked the boss, "The person who bought the knife? Did you leave your contact information?"

The boss nodded, "Yes!"

He quickly dug out the records and handed them to the police.Just because he was afraid that something would happen to the sharp knife, he deliberately left the customer's contact information.

Yu Su called over according to the phone number, and frowned when he heard the prompt tone on the other end of the phone, "No one answered."

The boss was so frightened that he fell down on the stool, and it took him a long time to react. He asked the policeman, "What happened to this knife? Am I supposed to be responsible?"

"I'll talk about your responsibilities later. Is there surveillance here? Do you remember? What did the person who bought the knife look like?" Yu Su said, and sent a text message to the police station.

The boss shook his head helplessly, "No, who in an old shop like ours would want to dress up for monitoring! But I still remember what that person looked like!"

"Wait a minute? Come back to the police station with us and describe that person's appearance." After Yu Su said, he walked to the door of the store and looked around the street.

This street is an old street, with relatively little surveillance. When a car is parked in this kind of place, the traffic police will not come to post a note. It seems that the murderer did not choose the shop at random.

Akang arrived quickly in a police car. The owner of the blacksmith felt that he was innocent, but he still asked the small workers in the shop to go back first. Their shop had to be closed for a while.

It was already afternoon when Yu Su returned to the police station, "Physical evidence, take it to the laboratory for testing."

Wu Tao didn't eat until this time. He wiped his mouth and prepared to work. He looked at the three bags of iron filings that Yu Su handed over, "That's it? This? It's gone?"

"The murderer went to an old-fashioned shop on purpose. The boss only left his phone number. He called just now. No one answered." Yu Su wrote down the number and handed it to Gu Li. Now, real-name registration is required to purchase the number, and the public security system can find the number. Lord? Who is it.

Gu Li entered the phone number to inquire. After seeing the number ownership record, he immediately left the keyboard with both hands, and looked at the screen with a strange expression, "Lu... Yu team, this is Lu Lingling's number!"

Yu Su looked at the screen to make sure that the name displayed on the screen was Lu Lingling's name, and the ID card on it was also the same as Lu Lingling's.

"Captain Yu, the dossier is here." Lin Huaiyue handed the dossier to Yu Su, "Lu Lingling hanged herself in the laboratory wearing a white coat. A student? Parents were crying outside the school gate. The school responded that it was a student? The academic pressure was too high. Big, I can't think about it."

"As expected? It's a white coat." Yu Su took the file and looked through it. It seemed that the murderer's purpose was obvious, that was to guide them to investigate Lu Lingling's case.

Yu Su looked at the file, signed by Lu Lingling's family members, thoughtfully, "Lu Lingling's father, is his name Lu Wei?"

Thinking about it, he looked up at Qi Yi, "Qi Yi, bring Lu Lingling's parents here."

The daughter? Died? Unexplained. Her parents had the biggest motive for committing the crime for revenge.

Lu Ci hurried upstairs with the report in hand. Seeing that Deputy Team Qi had just left the office, he hurriedly asked, "Has Team Yu come back?"

Seeing that the road is hard to come by, Yu Su immediately waved his hand in such a hurry, "I'm here? Do you have any new discoveries?"

Lu Ci handed the report to Yu Su and said, "We detected progesterone in the body of the deceased."

"Ah?" Jiang Miaomiao expressed doubts, "Progesterone? Isn't ketone a hormone secreted by women? How could the deceased be a man? Yes?"

Lu Ci nodded, progesterone, also known as progesterone, is a female-specific hormone, and men generally don't take it.

He pointed to the data in the report, "Moreover, the progesterone in the deceased's body was excessive. He took it for half a month, which has achieved the effect of chemical castration."

"That is to say, during the period when the murderer imprisoned the deceased, he has been giving him progesterone hormones?" Yu Su concluded his statement.

Lu Ci nodded, "That's what it means."

"You go? Find out which hospital has been opened recently? There are so many hormone drugs." Yu Su said to the police officer on the side.

"Yes!" The police officer responded.

Yu Su glanced at his watch, Qi Yi led someone? It was still a while before he came back, Yu Su turned to look at Lin Huaiyue, "Are you feeling better? Come with me? A trip to University A?"

Since we want to re-investigate Lu Lingling's case, we must go to the place where the crime happened.

Lin Huaiyue immediately put on his coat and followed Yu Su when he was looking for a job in his position. He saw him walking past the motorcycle and heading for the garage.

"Don't you ride a bike?" Lin Huaiyue asked.

Yu Su got into the bus, drove up to Lin Huaiyue, opened the passenger door, and said to him, "Team Yu misses you, get in the bus!"

Ever since he had Lin Huaiyue by his side, he seldom thought about the past. Now that he was sure that Azhou was still alive, his condition was much better than before. At least he was able to drive without any problem.

Along the way, Lin Huaiyue looked at Yu Su many times to make sure that there was nothing wrong with him, so she let go of the hand that had been holding on to the safety rail.

"I've been thinking about Lin Jiajia and Liu Jiao's words for the past few days." Lin Huaiyue leaned back on the seat and meditated.

Yu Su: "Huh? Tell me."

"Liu Jiao said that Lu Lingling suddenly asked her to borrow money, so why did she borrow money? Is there any direct connection between not raising money and her death?" Lin Huaiyue was puzzled.

Lin Jiajia saw that Lu Lingling had logged into the background of the live broadcast, that is to say, Lu Lingling was a person participating in the live broadcast, so her income should be similar to that of Jiang Yuan and the others.

"There is no movement of her funds in the dossier. Gu Li is already investigating. The case has just come to us. It will take some time to investigate what happened a year ago." After Yu Su said, he stopped Their school gate guards showed their police IDs and drove directly into the school.

The district police station classified this case as a suicide|suicide case, so the investigation was not detailed, and a lot of evidence needed to be supplemented by them.

After getting off the car, the two immediately went to the counselor's office of the Department of Chemistry.

The counselor was a little surprised when he heard that the police came for the case that happened a year ago, "Isn't that case closed?"

"The police re-examined the evidence of Lu Lingling's case and found some omissions, so I came here to add." Yu Su did not announce their case handling process. After all, this is a school, so it should not cause unnecessary panic.

Mentioning Lu Lingling, the counselor still felt a little regretful, "Lingling is a good student? She is motivated in her studies, and she even came to my place as a teaching assistant? She usually looks cheerful and lively, but I didn't expect this to happen suddenly."

"How is Lu Lingling's interpersonal relationship? Has there been any feud at school?" Lin Huaiyue asked tentatively.

The counselor thought for a while and replied: "No, she is very enthusiastic and will take the initiative to help students with learning difficulties. Oh, by the way! She is also a member of the school security committee, so she will come into contact with one or two bad people. Students? But I didn’t see any conflicts between them.”

Yu Su asked: "What do you mean by bad students?"

The counselor didn't even think about it, and said directly, "It's just Chen Yifan and the others."

These people? They are well-known bullies in the school, and they use their family money to run amok.

No, I heard that Fang Ye's father died last night. He usually doesn't come to school. In the future, without the support of his family, he probably won't come again.
