Profiler 2: Criminal Investigation Brigade

Seeing Jiao Yang standing in the room in a daze, Hou Xiyong couldn't help saying: "This is too evil! Boss, what do you think is going on here?"

Jiao Yang looked at the box of milk, and suddenly said: "There are only zero times when a man cheats, the first time and the nth time. Wen Caiyu is going to go abroad soon, so of course I want Li Jianxi to come and relive the old dream. Leave a thought before leaving. Who knows, something in the cabinet suddenly fell out. Li Jianxi might recognize it, it was Xinxin's thing, and he realized that Wen Caiyu was the murderer who killed Xinxin. He acted on impulse kill."

Just as Hou Xiyong was about to speak, Jiao Yang gestured at him and shook his head.

After all, Hou Xiyong was the one who followed him all the time, so he immediately understood, and said: "Yes, sir, I think it's the same. There are strange people here, let's go first!"

The two closed Wen Caiyu's room, and when they came downstairs to the police car, Jiao Yang calmly instructed Hou Xiyong in a low voice, "Go back to the office and find a set of electromagnetic interference equipment."

Hou Xiyong was stunned, then he reacted and said, "Okay, I'll do it right away!"

As a result, as soon as the police car drove forward, they saw the police car in the group of Shen Rui and Mo Ke, and were stopped by Wang Yaru.

Wang Yaru was wearing homely pajamas, with disheveled hair, threw herself on the front of the car, and cried out, "You can't catch him! My heart is dead. If you take him away again, how will I live?"

Although she is not young anymore, she is a lesbian after all, and she is still a little disheveled.Shen Rui and Mo Ke looked at each other, not knowing where to start to persuade Wang Yaru.

Jiao Yang opened the car door, walked out of the police car, bent down, and said to Wang Yaru in a low voice: "At present, Li Jianxi only appeared at the scene of the crime and needs to assist us in the investigation. It is not clear whether it is his problem. Originally, he was already at the farm. The Academy of Sciences has asked for leave, and no one in the academy will pay attention to whether you are at home. But now in the dead of night, you are making such a noise, which has attracted the attention of neighbors, and everyone will know that Li Jianxi is involved in the case. If he comes out without incident, do you think he will Officer, can you continue to do it?"

Wang Yaru was startled, moved her lips a few times, but didn't say anything, and moved away trembling.

Jiao Yang asked Mo Ke to send Wang Yaru, who was in a bad state of mind, back, contact Li Jianxi's relatives and friends, and find someone to watch her.

He and Hou Xiyong returned to the bureau together, found a set of high-precision, high-power anti-eavesdropping, anti-monitoring electronic equipment detection jammers, and found a card reader and a large-capacity memory card, and replaced it with a new car. The conspicuous car quietly returned to Wen Caiyu's house.

For the sake of caution, the two did not turn on the lights. As soon as they entered the door, the blue indicator light on the detector turned on.Jiao Yang activated the shielding signal device.

The two waited for a while, Jiao Yang put on his gloves, went straight to the half-filled milk box, and gently took out the unfinished milk box by box.Then put the bottom of the box and shine it on the flashlight on the phone.

Inside the general carton, there is a layer of corrugated cardboard.Jiao Yang carefully uncovered the cardboard, and sure enough, there was a small bug in the hollow space of this layer of cardboard.

"Oh……"

Hou Xiyong opened his mouth wide in surprise, and just about to make a sound, he suddenly covered his mouth.

Jiao Yang took out the memory card nimbly, read the content inside with a card reader, copied it out, and put it away as it was.

After getting in the car, Hou Xiyong whispered, "I'm so stupid, who is this? It's so powerful!"

"This is why the murderer can step by step, always take the initiative, rush ahead of us, and clean up the scapegoat at any time."

Jiao Yang said: "If you want to know who he is, just ask Li Jianxi."

The two turned on the detector again and came to Li Jianxi's home.In order to fear that Wang Yaru, who was emotionally unstable, would reveal her target, she had been taken back to her home by her younger sister.

Now in Li Jianxi's house, only Li Jianxi's old father who came in a hurry.

Jiao Yang said: "Old man, don't worry. We can return Li Jianxi's innocence soon.

Witnessed by the old man, the two reopened the shield, took out the bug in Li Jianxi's house as before, copied the contents, and put it back as it was.

The two returned to the police station and first listened to the contents of the bug found in Wen Caiyu's house.

It was found that the monitoring content in the memory card was very short, only a few hours, and Li Jianxi came at the very beginning.

Hou Xiyong said: "This man is really a thief, I thought I could directly find the evidence of his murder!"

Jiao Yang said: "This person is good at calculation, it is impossible to leave such obvious evidence. Therefore, he should have replaced the memory card before Li Jianxi came to Wen Caiyu's house. And the time to replace the memory card is The exact time of Wen Caiyu's death. Although the memory card is not enough to prove who is the real murderer, it can already prove that Li Jianxi is not the murderer."

In the reception room, Mo Ke and Shen Rui were asking about what happened before and after Li Jianxi.

Jiao Yang came in and asked, "Who brought the fruit basket and milk at your house? We found a bug inside."

Li Jianxi, who was dumbfounded, raised his head after a while, "What, it's him?!"

Jiao Yang gathered a few people in the police station and said: "Today is Friday, and it has been more than ten days since the incident happened. I have found the real suspect. In order to get more evidence, I am going to lure the snake out of the hole. This week everyone have to work overtime."

Hou Xiyong said: "It doesn't make sense, you assign tasks!"

On Saturday morning, technical detectives worked overtime to detect that there were only traces of Wen Caiyu's use on the tableware at the scene, and there were no fingerprints on the murder weapon, the fruit knife, or the child's phone watch.On the schoolbag, only the fingerprint of the victim Li Yi was detected.After identification by Wang Yaru, it was also confirmed that the phone, watch and schoolbag belonged to Li Yi.On the day of the incident, she took this watch and schoolbag to the painting tutoring class.

Yu Xiao said: "The murderer is so cunning that he didn't leave any fingerprints behind!"

Hou Xiyong said: "However, there is no way to prove that Wen Caiyu was the murderer of Li Yi, or that she was killed by Li Jianxi."

Jiao Yang said: "The murderer must wear something like gloves to commit the crime, without leaving his own fingerprints. But if there are only the victim's fingerprints on it, it cannot be used as physical evidence.

Therefore, the murderer can only erase all the fingerprints on these things.In this way, it can be completely pushed to Wen Caiyu and Li Jianxi.It is said that the fingerprints on the phone, watch and dagger were cleaned by themselves. "

Yu Xiaoguang shook his head and said: "This murderer is too poisonous, I don't know what hatred these people have against him!"

"Let Professor Lu explore the murderer's psychological world."

Jiao Yang said: "We are only responsible for arresting him and closing the Internet cafe!"

Hou Xiyong and Yu Xiaoguang came to Wen Caiyu's room again.

Hou Xiyong said cursingly: "Fuck, no one is allowed to rest on the big weekend, and I have to come here to continue to investigate the evidence! It's just such a small broken room, one room and one living room. It was turned upside down yesterday. What's the use of it?" Did you check?!"

Yu Xiaoguang said: "It's okay, it's just a matter of a few days to solve the case. Yesterday, there was an old lady in the dormitory building who went to the bureau to report the situation, saying that she saw a man taking Li Yi away on the day the case happened."

Hou Xiyong said: "Don't talk nonsense again? I saw it that day, why did it take more than ten days to say it?!"

Yu Xiaoguang said: "I heard that it was an old lady in her 70s surnamed Jiang who didn't go out easily, but she saw it when she went out to bask in the sun that day. People of this age don't read books, newspapers or mobile phones. His nanny Didn’t people know about these things when I asked for leave and went back to my hometown, and I only talked about these things with the old lady when I came back?”

The two of them pretended to make a mess of rummaging, and then went back home.

In the past few days, while waiting for the fish to take the bait, Jiao Yang has not been idle at the same time, asking his comrades to search everywhere for evidence that the murderer bought milk and fruit baskets.

Tuesday is National Day.On the morning of the first day of the holiday, Jiang Aihua heard the doorbell ring and went out to open the door.

A man in his thirties came in with a box of milk and a fruit basket, smiled slightly and said, "Sister Jiang, let me see Aunt Jiang."

"oops!"

Jiang Aihua closed the door, quickly moved a few steps aside, and said in a trembling voice, "You, you came here as soon as you saw it, why did you bring something?"

Jiao Yang came out of the study with his hands behind his back and said, "Hi, Section Chief Li."

Section Chief Li was taken aback when he saw Jiao Yang, "Captain Jiao, why are you here?"

"Come and catch the murderer..."

Before Jiao Yang finished his sentence, when he raised his head, Yu Xiaoguang and Hou Xiyong rushed out from the kitchen and bathroom on both sides together, twisted their arms and pressed their shoulders, pushed Section Chief Li to the ground, and handcuffed him directly.

"What are you doing?!"

Section Chief Li, who was pinned to the ground, struggled and said, "Why do you arrest me?!"

Jiao Yang disassembled the bottom of the milk, and took out a diaper from the interlayer of one of the corrugated cardboard boxes.Although the murderer cunningly used three different types of bugs, the results have been fruitful in the past few days, and these have nothing to do with the overall situation.

"Section Chief Li,"

Jiao Yang said: "Can you explain why you put a bug in the gift you give to others?"

"I...I don't know!"

Section Chief Li argued: "I just came to visit Aunt Xia Jiang, I don't know who put the bug in!"

"Oh, that's such a coincidence."

Jiao Yang said: "The bug was also found in the milk carton you gave to Li Jianxi and Wen Caiyu. Which milk manufacturer is this doing charity? It costs tens of dollars to sell milk, and it costs hundreds more your bug?"

"I don't know that!"

Section Chief Li sneered: "If you want to ask, just ask the manufacturer!"

"I don't think it is necessary to ask the manufacturer, but it is more useful to ask the electronic technology market."

Jiao Yang said: "Li Zhuoqun, when we found out that you have no online shopping record recently, our police officers have inspected many electronic technology markets in Shencheng City in the past few days. Finally, in a corner of a market, we found illegal sales. monitoring and monitoring equipment.

After seeing the photo, the owner quickly recognized you and bought multiple miniature monitors from him. "
