Chapter 149 Pollution

Bai Ya put the last box of physical evidence on the inspection table, "Thank you everyone for counting every physical evidence in each case, and re-examining any doubtful items."

"Yes." The inspectors answered in unison, then lightly picked up the evidence bag in front of them and started working.

Jiang Xiyan sat quietly in the corner of the examination room, inspecting every piece of physical evidence, and suddenly found a bag pressed at the bottom, which contained a key, and no one seemed to have noticed this before.

Could it be a missed check?

Jiang Xiyan entered the number on the evidence bag into the system. This number is recorded, but there is very little information about this key in the record.

It is only known that this key came from Lu Mengyue's case, but there is no record of which door to open.

Bai Ya caught a glimpse of Jiang Xiyan in a daze, and walked over to check curiously. Seeing that the object of his doubts was a key, he explained: "This key is some evidence brought by Lu Mengyue's parents when they called the police to cooperate with the police. At that time, the police went to Qin’s house and places Lu Mengyue frequented to compare, but they couldn’t use this key to open the door, so there will be less description in the records.”

Jiang Xi said: "It turns out to be like this."

This is an old cross key, the door is rarely used now, it should be the previous house.

Since it was used by Lu Mengyue during her lifetime, there must be traces of her existence, but they have no clue yet.

"Senior Jiang, Team Song brought you breakfast again!" The inspector who came to change shifts saw a breakfast on the table before entering the door, and there was only one person who missed their physical evidence department so much.

He put the breakfast in the office, put on clean clothes and walked into the inspection room, and added, "Senior Jiang, your breakfast is getting cold, take a rest!"

"Song Zhou?" Jiang Xiyan remembered that Song Zhou had said that he was going to the hospital this morning, and he should have left for a while now.

Bai Ya stretched his waist, he didn't rest all night, his mind was a little unable to turn, "Yes, let's take a break!"

He had no one to help him buy food, and he didn't know if there was breakfast in the cafeteria.

Jiang Xiyan glanced at the key again before leaving, and was about to go back to the office to recuperate when he heard the phone in his pocket vibrate.

Seeing that it was Song Zhou calling, he answered immediately.

"Go further, and turn left at the intersection ahead." Song Zhou pointed Tao Yiran in the direction, and then said to Jiang Xiyan on his phone, "Xiyan, Geng Hao said that the Shuoxing Clubhouse is Lu Mengyue's first place. At the scene of the death, you and Bai Ya will come over with the toolbox in a while, and the location has been sent to you."

Jiang Xiyan got up immediately, "Okay, I'll be right there!"

He glanced at the location of the mobile phone and prepared the toolbox for the survey.

Bai Ya, who was going to have breakfast, ran back when he received a call, and set off with Jiang Xiyan.

The shop owner, who was about to come to open for business in the morning, saw two people in front of his house looking in the window, thought they were here to find fault, pointed at them and shouted loudly: "Hey, what are you two doing!"

Song Zhou heard the sound and looked around, and saw someone walking towards them with the broom in front of the shop next door, took out his ID to identify himself: "Hi, I'm a policeman."

The boss was stunned, and immediately dropped the broom in his hand. He bent down and cleaned the front of the shop next door, and shouted, "What's wrong with your house? How can you do business if you don't clean the door!"

Seeing that the store owner rushed out to curse people, he quickly put the broom aside, walked up to the two police officers and asked, "Are the two police officers okay?"

The police came to the store last time and asked some things he didn't understand. This time, they came again. Could it be that something really happened to them here?

"We want to go into the shop, is it convenient for you, boss?" Song Zhou asked.

The boss hurriedly opened the door, "Of course it's convenient, please!"

Song Zhou thanked him, and led Tao Yiran into the shop. When he heard the sound of a car stopping outside the door and familiar footsteps, he knew it was Jiang Xiyan and the others.

"Team Song, here we come." Bai Ya looked around the shop, thinking where to start the search.

Song Zhou turned around, looked at Jiang Xiyan and Bai Ya and nodded, "As usual, the scene belongs to you, and the people belong to us."

"Okay." Jiang Xiyan put the inspection box on the ground and opened it, put on gloves and a mask, and carefully inspected it in the shop with the prepared luminol reagent.

As soon as the clerk who just came to work came in, he was stunned when he saw the situation, and turned to the boss next to him and asked, "Boss, what's wrong?"

Song Zhou asked the clerk again the question he asked the boss just now, "Look, have you met these people?"

He handed the photos of Qin Yuan, Lu Mengyue, Qin Anran and Qin Yan to the clerk.

The clerk shook his head, "I don't remember, it's definitely not our regular customer."

There are usually a lot of customers in their store, how can they remember them all?

"Xiaojiang, here!" Bai Ya beckoned to Jiang Xiyan, he pointed to the wall of the private room and said, "There is a fluorescent reaction here."

Jiang Xiyan pointed to a table not far from the private room, "That table also has the legs, and the corner of the aisle."

Bai Ya pointed to the side of the door, "There are also here."

These traces have faded, and there may be some blood stains that have been seriously polluted with the passage of time, so they are basically invisible.

Fluorescent reactions are not suitable for all sites, especially stores that are open to the public.The store receives countless customers every day, and then uses disinfectant to scrub the store over and over again, destroying the original site, and they can only catch traces from the dead corner of cleaning.

But just the bloodstains in the dead corner, it can be seen that there was indeed a crime here before. There are so many bloodstained places, I am afraid it is not a simple fight.

Jiang Xiyan synchronized the situation at the scene to Song Zhou, "Team Song, this is indeed the scene of the crime, but the pollution is too serious, there is no way to determine whether this is the scene of the first crime."

In the past 25 years, they are not even able to find the fluorescent reaction, let alone extract the blood for analysis.

Song Zhou looked into the store, and several places were marked with signs. It seemed that these were the places where bloodstains were found.

Looking at the location of these bloodstains, I'm afraid it's not as easy as Geng Hao said, Qin Yuan might have killed Lu Mengyue.

The clerk looked curiously at the box that the police frequently entered and exited, and suddenly remembered something, "Speaking of which, there was indeed a strange incident in this box a few months ago. Someone called and booked this box that day. In the evening, a guest I came in in a hurry, I asked him what he wanted to eat, he walked straight to the box without saying anything, I thought he had an appointment, so I followed him to place an order."

As he said, he led the police to the box, pointed to the round table in the box and said, "After I followed him in, I found a letter on the table. It was snatched away by the guest. He opened the letter and read it twice, then tore up the letter suddenly like crazy, and then left. "

"Is the shredded paper still there?" Song Zhou asked.

The clerk shook his head, "Why do I keep this thing, he tore it up, of course I swept it away as garbage."

Is this... important?Will he be scolded by the police?But who would have thought that shredded paper and garbage had something to do with the case?

"However..." The clerk looked at the four photos that the police gave him just now, and took out one of them, "The customer does look a bit like this person, but I'm not sure."

It's been a few months and his memory isn't that good.

The polluted scene, the evidence thrown away as garbage, the forgotten facial features... Although this is not the first time this kind of thing has happened in the case investigation, Song Zhou is still a little helpless.

"Is there any reservation information for this box?" Song Zhou looked for another clue.

As long as they pass by, they will leave traces. They can't just dig into the horns and find another way. If they can't find the truth, at least they can eliminate the wrong option.

The boss responded, "There are indeed."

He said, walked to the front desk, took out a notebook and looked through it, "I booked a box but didn't come, I have marked it."

The clerk added: "Three or four months ago, probably not long after the Spring Festival."

He was somewhat impressed that the store was very busy during the Spring Festival, and when the customer came, the business in the store was much less than during the Spring Festival.

"I found it, this is it." The boss pointed to the part of the notebook that he had crossed out with a red pen.

Song Zhou took the notebook, saw the guest information written on it, frowned and whispered: "Ms. Lu?"

He immediately called Su Mian, "Su Mian, are you free, check the number for me?"

"Okay, Captain, tell me." Su Mian clamped the phone to her neck, entered the number reported by the other party into the system, started to inquire, and then reported, "Captain, the identity registration information of this number is Qin Anran, but... Lu This is also the number Meng Yue used before she was alive."

More than [-] years ago, there was no such thing as real-name registration. After that, unless it was done by illegal means, everyone had to have a real name.If Qin Anran wants to keep the number of her biological mother, she has to register, otherwise it will be suspended.

"It's Qin Anran again." Song Zhou looked at the reservation information in the notebook with a dignified expression.

When I went to Geng Hao's house to search for evidence, the physical evidence brought back a notebook of Geng Hao.

Geng Hao has been secretly investigating Qin Yuan's disappearance. His notebook mentions that Qin Yuan had some abnormalities before his disappearance. He once drove to the Shuoxing clubhouse by himself and refused to let anyone follow him.

It seems that someone deliberately let Qin Yuan come here, the purpose is to let him "return to his old place" and read that letter.

Judging from Qin Yuan's attitude, he can get two key pieces of information, the box in the Shuoxing Club and the letter.

And the person who arranged all this is most likely Qin Anran, but what is her purpose for doing this?

"Captain, what shall we investigate next?" Tao Yiran asked.

They couldn't find Qin Anran's whereabouts for the time being, and finally waited until Geng Hao woke up, but with so little information on the scene, they felt a little lost.

After thinking about it in his mind, Song Zhou shook his head and said, "We can't find Qin Anran, isn't Qin Yan still in our hands? Keep asking."

The voices of the two reached the ears of Jiang Xiyan and Bai Ya, and they also looked at each other.

Bai Ya suggested: "Let's go to Qin's house later to have a look."

It's not that he doesn't believe Team Song and the others, but that there are contingencies. If Qin Yan refuses to speak, the police won't be able to detain him for long. When Qin Yan returns home, it will be difficult for them to search for evidence so easily. .

Jiang Xiyan nodded in confirmation, he also meant it.

After Qin Yan was taken away by the police, Xian Kan went to Qin's house to check. The room was cleaned deliberately, but no suspicious clues were found.

But it was going to be summer soon, and the fire in the fireplace was still on, as if something had been burned, but Qin Yan was very smart, picked up the ashes with a wooden stick, and burned them very thoroughly.

Such ashes, physical evidence is powerless to restore.

But the more Qin Yan wanted to cover up, the more it meant that there was something wrong with that house.

Because a blood reaction was found in the shop, the police needed to borrow it for a while.

The boss's face was livid, and he regretted the past. At that time, he should not have been greedy for petty gains and sold this shop. Only now did he know that they had "coexisted" with the murder scene for more than [-] years.

Hearing that the police wanted to use it, he agreed without thinking about it.He didn't know before, but now that he knows, he needs to take some time to relax.

The inspectors stayed in the store to continue the inspection, Jiang Xiyan and Bai Ya took two police officers and drove to Qin's house.

Song Zhou and Tao Yiran returned to the police station, walked into the interrogation room, and sat down in front of Qin Yan.

Qin Yan looked at Song Zhou calmly, and greeted Song Zhou as if seeing an old acquaintance, "Hello, Captain Song! Do you have anything to do with me?"

Song Zhou stared at the other party, and asked in a deep voice, "Where is your sister?"

Qin Yan spread his hands, shook his head innocently and said, "How do I know this? I have been abroad for so many years, and my sister has long been estranged."

"Unfamiliar?" Song Zhou smiled, "Since she is so unfamiliar, she gave you all the shares of Yaoming Group under her name? It turns out that your sister is doing charity."

Qin Yan was still so innocent, and said with a light smile, "Maybe it's because I'm the male of the family!"

As he spoke, his back molars were clenched slightly, and there was no smile on his face.

Jiangjing Building is located in the most prosperous area of ​​Jiangxin District, and the Qin family bought the highest third floor of the building in one go.

Bai Ya pushed open the door of Qin's house, it was the same as when they came last time.

Jiang Xiyan put on his mask, shoe covers and gloves, and walked slowly into Qin's house.

Although the Qin family is large and luxuriously furnished, it always has a cold feeling.

The three floors are connected up and down. The first floor is the living room, dining room, chess and card room and cinema, the second floor is the guest room and study, and the third floor is the master bedroom, side bedroom, and an open-air swimming pool.

The house is cleaned every once in a while, and there are not many people living in it, so it looks very clean.

Both Qin Yan and Qin Anran lived in the side sleeper on the third floor, which had been their key survey site before, but this time Jiang Xiyan focused on the second floor.

There are three guest rooms on the second floor, the furnishings are basically the same, it doesn't look like anyone has lived in it, and no DNA was found in the room.

Immediately, he set his sights on the study room on the second floor, where several bookshelves were lined up, like a small library.

And the side door of the study was connected to a lounge, which he found strange last time.The windows here were welded shut, the ventilation ducts were fitted with iron mesh, and the layout of the room was very simple, with only a bed, a desk with a mirror, and a TV.

It is indeed like a lounge, but is it too depressing to be a lounge?

In the interrogation room of the police station, Qin Yan crossed his legs, leaned on the back of the chair wantonly, and suddenly asked, "Captain Song, what date is it today?"

Song Zhou thought about Qin Yan's intention for asking this question, and then replied, "It's the 27th."

Qin Yan nodded in satisfaction, and put his legs down, "I've been playing with you for so long, it's time to leave."

Seeing Song Zhou staring at him all the time, he smiled comfortably, got up and said: "Captain Song, the most important thing in business is honesty. If I say I haven't killed anyone, I haven't killed anyone. You can't find anything. I'll go." No, Team Song doesn't need to send it away!"

After finishing speaking, he left the interrogation room as if no one else was there, and walked towards the gate of the police station.

Watching Qin Yan leave by himself, Tao Yiran looked at the captain and said anxiously: "Captain, do I want to bring him back?"

Song Zhou shook his head calmly, he was already mentally prepared for what happened today.

In fact, what Qin Yan said is correct, the police did not find any evidence of his murder, and now they only detain him because they think he is a suspect and cannot last long.

But detaining the person is of great benefit to the police. The economic investigation side can freely investigate at the Yaoming Group, and their physical evidence can also enter the "routine" Qin family's "routine" evidence collection.

There is indeed not much evidence now, but next time, he will not let Qin Yan go.

Qin family.

"Okay, I see." Bai Ya received a call from the team, asking them to leave the Qin family, and he immediately shouted to the study, "Xiao Jiang, we have to go."

Jiang Xiyan heard the sound and responded, "Okay, I'm here."

He knelt down and was about to put away the inspection box. When he shifted his gaze, he caught a glimpse of a loose baseboard in the corner.

He hesitated for a while, then decided to take one last look, walked quickly to the corner, and with a little effort, the baseboard was removed, which should have been removed before.

This baseboard seemed ordinary, but Jiang Xiyan followed the light and saw a fingerprint on the inside.
