Please don't stick to Officer Qi [criminal investigation]

Huang Yuanliang was indeed close to Xie Yan, and he was the one who recommended Xie Yan to become a consultant.

However, Qi Lin believed in Huang Yuanliang, and even more in everyone in the police station.

Then, the problem must not be from within.

There is no internal response, and you want to know the information of the police station, then the only option is——

Qi Lin signaled Xiao Wang to be silent, then touched under the table lightly, and finally pulled out a thin data cable.

Continue to touch along the data line, it is a small black box.He pulled out the entire instrument and gently placed it on the table.

Shi Le immediately understood, took a wooden box, packed the instrument, and put it away from several people.

Xiao Wang is also smart. Even after seeing the instrument, he chased the wooden box madly for a long time, crying and making noises, complaining a lot before returning to his original position.

"The drama is a bit over." Seeing Xiao Wang sitting across from him, Qi Lin lowered his voice and said, "But it's okay, Xie Yan doesn't know you well, so I probably can't hear you."

"This thing is really Xie Yan'an's bug here?" Xiao Wang was puzzled, "How did he install it?"

"He came to the police station once before, and it was probably installed at that time. There is glue on the back of this bug, so it should be more convenient."

After speaking, Qi Lin looked towards the door of the office.

He clearly remembered that after Xie Yan came in from the door that day, he walked around the cabinet twice before walking to the table.

Well, there should be more than one bug.

Qi Lin stood up and searched for several hidden places that did not affect the transmission of sound. Finally, he found a bug under the pennant and the flower pot.

He cut off the remaining two bugs, leaving only the one Shi Le put in the box.

"That should be all." Qi Lin put the bug on the table, "Xie Yan didn't wear gloves that day, as long as he can prove that the fingerprints here are Xie Yan's, then he can be searched. Xiao Wang, go Get a completely soundproof box and keep that bug safe."

Xiao Wang nodded.

Shi Le took a camera to take pictures of these bugs to collect evidence, "This thank you is really powerful, and I glued things in such a short time."

"Not necessarily, we still have to test it with a professional instrument. It is not ruled out that these things were placed before."

"Probably not. In the wax figure case, Xie Yan is more like rushing over. Do you still remember the rose petals in the wax figure case?"

"Of course, two pieces, one piece in the wax figure, and flowers on the things sent later."

"Yes, it's two, which is very strange. It stands to reason that one is enough. The things that were sent later were flowers, which was obviously provocative, but there was another piece in the wax figure itself, which made the bouquet somewhat redundant. .”

"Maybe, he didn't know there were flowers in the wax figure at all, because he came here temporarily, and he didn't know about it until he was invited to be a consultant." Qi Lin leaned into Shi Le's ear, "Because of this, you doubt him. He didn't install the bug until he came to the police station later, otherwise, he wouldn't make such a low-level mistake, right?"

"That's what I mean."

"Understood." Qi Lin leaned back on the chair.Xiao Wang scanned the office with a magnetic field meter, but found no other wiretapping devices.

"Then it's safe." Qi Lin breathed a sigh of relief, and his voice gradually became louder, "But what about the previous case? How did he know about our actions?"

"He didn't need to know before." Shi Le analyzed, "In the Sapphire case, the three people are not good people. Their greed is obvious. The words of thanks don't need to be used as motivation, they just need to be an information provider. And junior high school In the case that happened, Chen Wen himself was malicious to Wang Zhi, the case is not complicated, and there is no need for behind-the-scenes surveillance."

Qi Lin was lost in thought.What Shi Le said was very reasonable and convincing.Starting from the wax figure case, the case gradually developed in a complicated direction.

"Then go check the fingerprints, and start arresting Xie Yan after the check."

Shi Le was very worried, "Will it be too late to arrest after the investigation? Now Xie Yan probably has left Qingcheng."

Qi Lin shook his head, "No."

Absolutely not, the target of the man behind the scenes has always been himself, not others.

If he runs away now, the game he set up before will be wasted, and the chess pieces in his hand - Xiao Yuxuan and Wang Bai - will become unnecessary.

Qi Lin firmly believed that Xie Yan was still in Qingcheng, and was watching him from a certain corner.

……

As a result, Qi Lin was not kept waiting for long.When reporting work with Director Xing, Xiao Wang sent in the documents.

"Put it there." Xing Ju thought it was a document for himself, waved his hand, and signaled Xiao Wang to put the things on the desk.

Xiao Wang is a little afraid of Xingju.He glanced at Qi Lin, told Qi Lin with his eyes that this was for him, and obediently put it on the table.

Qi Lin looked at Xing Ju.

Xing Ju is making tea.

"I don't know what this is. A lot of documents come to me every day, so I'm tired." He poured a full cup of Tieguanyin for Qi Lin.

Qi Lin put his palm on the cup, feeling the heat rising from the mouth of the cup, "It was still easy when I was in Jiangcheng. At that time, we went to handle cases together, and I followed behind, teaching everything."

"It's been many years, why does it feel like it was yesterday." Xing Ju held up his teacup, "That's right, you didn't know anything at that time, but now you can take care of yourself."

"It's a good teaching." Qi Lin said.

Xing Ju paused while sipping tea, "You really think so?"

"of course."

Xing Ju chuckled, "But you didn't learn well. I taught you so much before, but you didn't listen to many important things."

Qi Lin was stunned.

Xing Ju continued: "I told you the first time, don't be swayed by your emotions, don't be blinded by your own eyes. But, from the first case, you have forgotten this. I know, these cases It's about you, but because it's about it, you need to look at things from a third-person perspective, don't you?"

He sighed, "I didn't want you to participate in a lot of things, but that kid Shi Le believed in you and helped you a lot, both overtly and secretly."

After finishing speaking, Xing Ju put down the teacup, "If I guessed correctly, that document should be for you, go and get it."

Qi Lin went to the desk and brought the folder, but before he opened it, Xing Ju said, "You should already know about your father."

Qi Lin stopped what he was doing, "Is it Shile?"

"No, he didn't tell me. I saw Shi Le took the red USB flash drive on the surveillance. This kid can't hide the secret, and he will tell you sooner or later." Director Xing walked to Qi Lin and walked from the door. He took out the dossier that had been prepared in the deep black wooden cabinet, "This is the dossier from that year, a photocopy, you can take a look if you are interested."

Qi Lin frowned.He first put down the information about Xie Yan, and turned to check the events of the year.

It's not far from what he expected, and there really is no doctor or that kid involved.

So, it really was my memory that was wrong.

But about the kid and the doctor... what on earth did they have to do with their father?

Also, is that child Xie Yan?

In terms of age, it does match.Xie Yan was in the same class as Qi Lin, and in my memory, that kid was about the same age as Qi Lin.

"Thank you, I see." Qi Lin put away the documents, thanked Xing Ju, and then went out with Xie Yan's fingerprint identification.

In the office, he opened the appraisal report, and the results showed that the two were consistent.

"Okay, let's go and apply for a search warrant." Qi Lin didn't know how he could delay this matter for so long, and after going around and around, he finally suspected Xie Yan.

Before, all the scenes were done very clean, and there was no trace of thank you words left.Qi Lin only knew that there was someone behind the scenes, but he couldn't find out anyway.

For some reason, everyone steadfastly protected Xie Yan's identity, and became "that gentleman" in their mouths.

Does "that gentleman" really refer to Xie Yan?

Or, there are other people behind the words of thanks.

Shi Le also had this doubt.When driving to Xie Yan's residence, Shi Le kept moving Xiao Wang's box on the passenger cab. He moved here and pressed there, and finally returned the box to Xiao Wang.

"What is this box for?" Shi Le asked Xiao Wang.

Xiao Wang packed the things and explained to Shi Le.There are reagents and purple light lamps for measuring blood reactions inside. When the purple light shines on places where there may be blood stains, the reagents can be used for detection.

As he spoke, he took out bottles of reagents, one by one, and Shi Le said, "This is phenolphthalein, this is benzidine, this is luminol, and this is sodium peroxide..."

No matter how you say it, Shi Le is a serious police officer. Although he can't recognize him, he has an impression of Xiao Wang when he says this.

"Why did you take these to Xie Yan's residence?"

Xiao Wang didn't know what to do with these.All the murders happened in other places, and there should be no blood reaction in Xie Yan's residence.

"Why?" Shi Le asked Qi Lin again.

Qi Lin didn't answer this question directly, but said: "Think about Wei Jingshan's matter, starting from when we saw him in front of the claw machine."

Shi Le recalled, "We saw him in front of the claw machine that day, then went to have a meal and returned to my house, and then...we were attacked by surprise."

"Yes, but the results of the forensic examination showed that Wei Jingshan's death time was before we were attacked, and his third spine had an abnormal forward-folding crack. How could it be possible for a backward execution to be forward-folding?" Qi Lin looked ahead and drove the car, "Your Majesty always suspected that it was not the scene of the first crime, but he couldn't find it because there was no information about the murderer. Now that there are clues, of course we have to rule them out one by one."

After finishing the last word, the car stopped downstairs in a magnificent residential area.

"That's it, the fourth floor." Qi Lin parked the car and asked Xiao Wang to take the good things and go up to the fourth floor from the elevator.There are only three households on the first floor of this community, and the one at the innermost corner of the corridor is Xie Yan's house.

"It's really rich, to live in such a luxurious community." Shi Le looked up at the relief ceiling engraved with Greek mythology, and said with emotion.

But the other two were in no mood to look up.Xiao Wang took the lockpicking tool from the suitcase, and as soon as he inserted it into the lock, Qi Lin supported his shoulder.

"Go and hide in the stairwell." Qi Lin lowered his voice, "I heard footsteps."

Yes, the footsteps were very light, but they did come from Xie Yan's house.
