Profiler 4: Criminal Investigation Team

Jiao Yang subconsciously stepped forward and said, "Mr. Meng?"

Meng Di paused, subconsciously said: "Yes, yes."

Jiao Yang nodded and said, "Mr. Meng also lives near here, how about doing a nucleic acid collection together?"

Meng Di smiled awkwardly, "I have already picked it..."

"So it is."

Jiao Yang took the initiative to shake hands with Meng Di and said, "Thank you for cooperating with our work, I have caused you trouble."

After he left, Hou Xiyong came over and said, "Boss, who is this guy? Why does he look so familiar to me?"

"Yes."

Yu Xiaoguang said: "It may be the neighbor of the deceased. I heard about it today and took the initiative to do nucleic acid."

Jiao Yang said thoughtfully: "It seems that he is quite enthusiastic."

With the cooperation of designated public security hospitals, the task force collected 5000 nucleic acid samples in a relatively short period of time.

At the same time, with the blessing of the artifact provided by Lu Yuanli, all the samples were processed in just a few days.

However, unexpectedly, none of the DNA samples matched the second person found at the scene, that is to say, after spending so much manpower, material resources, time and effort, they still haven't found the suspect.

Everyone felt very discouraged, but Jiao Yang, considering the fluidity of people in modern society and the possibility of suspects absconding in fear of crime, planned to submit a report to his superiors and apply for expanding the scope of DNA collection.After all, there have been cases in the past. In order to solve the case, the DNA of up to 10 people has been collected.

"The creditor called you, the creditor called you!"

Jiao Yang suddenly heard a funny phone ringtone, and then he remembered that it seemed to be the exclusive ringtone he set for Lu Yuanli that day.

Lu Yuanli said, "Have you not compared the suspect's DNA yet?"

Jiao Yang said speechlessly: "Jiao Du told you again? This big speaker!"

Lu Yuanli said, "Have you ever thought about comparing the duplicate DNA in the collected samples?"

Jiao Yang paused and said, "Why do you ask such a question?"

Lu Yuanli said: "I suddenly remembered a case from a long time ago. When investigating a serial killer, thousands of people were investigated, but no matching DNA was found. Later, an organization established a DNA database and absorbed this part of the data. When entering the information, the staff of the research institution accidentally found two duplicate dna data.

I speculate that the reason for this situation may be that the murderer was actually investigated at that time. He used some kind of cheating method and asked someone to collect DNA samples for him to deceive the police.However, since the original data has been obfuscated, it is no longer possible to track down the real murderer."

Jiao Yang was very surprised. He had a little impression of what Lu Yuanli said, but he didn't really believe it.In country M or in the West, thousands of people used to be a big project, but in our country, when nucleic acid collection is becoming more and more proficient and the process is getting more and more perfect, it is a bit hard to understand that this situation can still happen.

However, after all, they are composed of police officers, auxiliary police officers, community staff, and hospital staff. Several types of composition are put together on the spot, which is different from the regular medical system transfer procedures.From the perspective of criminal investigation, Lu Yuanli's speculation is actually very reasonable.Because everyone is eager to find the DNA that is consistent with the remains at the scene, but it is easy to ignore other things.Moreover, they now have artifacts in their hands. In theory, it is not difficult to pick duplicate samples.

Jiao Yang smiled and said: "Professor Lu is indeed Professor Lu. If you really find out, I will give you a credit... Oh, no, I will give you a few more monthly subscription cards!"

Lu Yuanli smiled lightly and said, "Then can I switch people to spend?"

There are two possibilities for substitution consumption... Jiao Yang asked after hearing this, "What do you mean?"

Lu Yuanli said, "literally."

Jiao Yang asked suspiciously: "Which team member of mine do you like?!"

Lu Yuanli chuckled and said, "Does it have to be a team member?"

Jiao Yang quickly went through it in his mind. The establishment of the special service detachment seemed to give each detachment a chance to shake off their burdens. Those who handed in were all capable but also had various problems. There were many thorns, half like men She doesn't have the temperament of a college student, which doesn't fit Lu Yuanli's aesthetics.That……

Jiao Yang wondered: "Could it be that you like female college students now? Do you think Xiao Ke is bouncing around all day, as lively as I was when I was young?"

"Honey,"

Lu Yuanli smiled and said, "Men's aesthetics are actually not as stubborn as you think. Even the broadest concept of youth and beauty is just a dynamic concept."

"Xu Mengzhen..."

Jiao Yang blurted out: "Could it be that you have changed your gender and like the mature and steady one?!"

This answer is quite interesting.Lu Yuanli said, "Why do you think so?"

"Because in our place, apart from me, Team Xu is the most outstanding! Have you never heard of Criminal Police 803... Oh, you didn't have this environment when you were young."

Jiao Yang smiled and said, "Then you've been here for so long, you should know a famous team, right?"

Lu Yuanli chuckled lightly and said, "I don't know. Probably when someone becomes the tip of a sharp knife, I'll know."

When he said this, he must have heard the phrase "the trump card is the trump card, the sharp knife is the sharp knife", tsk tsk tsk, looking at his state, looking forward to his husband Jackie Chan can still moisten things silently!It would be nice to be able to join a team sometime.Jiao Yang was fascinated for a while, and suddenly realized, "Wait a minute, is it really Captain Xu?!"

"It's a ghost, don't make wild guesses, solve the case well!"

Lu Yuanli hung up the phone casually, leaving Jiao Yang alone staring at the phone in a daze.

A few days later, the results of the comparison came out. Sure enough, the DNA samples of two people were exactly the same. However, unless they were identical twin brothers, this situation would never happen.

Jiao Yang looked at one of the familiar names on the report, and sighed, "There's no need to search any more, it's him, let's arrest him."

Meng Di was quickly arrested and brought to justice, Hou Xiyong grabbed three hairs from Meng Di's head, "Okay, I didn't run away this time!"

Of course, another person was also called to the city bureau.

Seeing this situation, this person immediately admitted that Meng Di gave him 1000 yuan on the grounds that collecting information this month would be a disaster. He had a good relationship with a community worker, so he took the opportunity to replace the DNA sample.

The comparison results came out soon, confirming that Meng Di's DNA data was consistent with the samples collected at the crime scene that year.

Jiao Yang took the testimony and evidence and immediately called for Meng Di to be interrogated.

Hou Xiyong put all kinds of evidence in front of Meng Di and said, "Tell me, what happened to that case back then!"

"Officer, I didn't kill anyone, I really didn't kill someone!"

Meng Di shouted: "Please believe me, it was an accident. I was in the third year of high school, and I was too busy studying. I wanted to relax, so I asked my neighbor sister to play a game. Usually no one cares about her at home. It was I who accompanied her and often invited her to eat. We have a good relationship, so she agreed.

At first we played with candles, ropes and so on, but she said to play with choking!I wanted to save her, I...I rescued her, but she was hanging too high, and I couldn't get it down after grabbing for a long time, and I couldn't untie the rope. I saw that she was out of breath, and I was very scared, so I ran away It's..."

A young girl in her prime died so inexplicably.Jiao Yang said in a deep voice: "Then why didn't you call the adults to rescue him, why didn't you call the police?"

Meng Di cried: "When I find out that something is wrong, she will no longer be able to admit it. Her grandparents are fierce and often scold people. They scold me when they see me looking for her. I'm afraid to let them know that I killed their children. will kill me!"

Jiao Yang came out of the interrogation room, Hou Xiyong followed and said, "Head, do you believe what Meng Di said?"

"What do you believe!"

Ke Luoluo said angrily: "He killed people! He was already an adult at the time, and an 18-year-old man who induced a 14-year-old girl to play this kind of game is a scum! He should be shot!"

"All right."

Jiao Yang said: "It is our responsibility to catch the criminal. As for the sentence, that is the responsibility of the judge. Let's go."

Seeing Ke Luoluo's angry look, Hou Xiyong hurriedly said: "Don't be angry, this kid is the least serious and inaction, there is a high probability of manslaughter, he can't get away!"

It was rare to get off work early today, so Jiao Yang went to the supermarket to buy some vegetables, and took them to Lu Yuanli's house.

Unexpectedly, Lu Yuanli was not at home.

Jiao Yang thought about it, anyway, it's so close, wouldn't it be nice for him to be the hostess?

Jiao Yang took a photo and sent it to Lu Yuanli, leaving a message: "The flowers are on the door, the dishes are on the table, and you are in my heart."

Lu Yuan left to attend a seminar, took out his mobile phone and saw Jiao Yang's message, he hesitated for a moment, should he answer this sign or... not?He always felt that the steps between them had already moved back too quickly...

Lu Yuanli thought for a while and said, "Then where are you?"

"In the pot. Come?"

"There's a meeting outside, we'll talk about it when we get back."

Putting down the phone, Lu Yuanli felt that he could at least get a score of 85 or higher if he was acting like a force.

After the meeting ended, An Ran sent Lu Yuanli back to Binjiang Garden.

As soon as he got out of the elevator, he smelled frying and frying.

Lu Yuanli couldn't help thinking, is it so obvious?It seems that the quality of this house is also very average...

He walked to the door of Jiao Yang's house, hesitating whether to step over and go straight to his own house, when the door opened with a "squeak".

Jiao Yang leaned out and said, "It's just in time for you to come back. Come and help me try a new dish? I made spicy oxtail."
