Chen Mu looked at the man who was holding his trouser leg and kept crying bitterly, and nodded heavily.

After returning to the police station, Chen Mu asked Yan Lingyun to extract Zhang Li'an's DNA information, and re-examine the body of the deceased.

And Chen Mu began to have a headache after calling up Zhang Li'an's information.

Looking at that child's performance, it should be a tough nut to crack.

After sorting it out, Chen Mu specially called Liu Binglei into the interrogation room as a clerk.

In the interrogation room, Zhang Li'an was already sitting in the interrogation chair.

His demeanor was relaxed, his shoulders drooped slightly, the corners of his mouth were raised, and his eyes were even surveying the interrogation room.

Don't pay attention to anything, probably the character of this teenager.

"Officer Chen, have you seen my information? Isn't it particularly dog blood. ”

Chen Mu didn't look at him, and looked down at the document, "Let's talk about it first, do you admit that you killed your fellow classmate Fu Huai." ”

"Yes. In the past six months, he has been the first in the exam, and if I don't kill him, I will definitely be beaten to death by my father. When he said that he was killed, Zhang Li'an said it with a smile.

Chen Mu looked at him at this time, "Then how you killed Fu Huai, please repeat it." ”

"It's not difficult at all." Zhang Li'an narrated with a smile, "First used Chen Haohao's stupid woman to incite the people in the school to isolate him, and then changed his account to treat him well, guide him, and then seduce him. As a result, he said that day that he was in a much better mood and wanted to thank me in person. I hid behind my phone and laughed like crazy, what a fool this is! It's obvious that I isolated him, but he actually thanked me, stupid, just stupid! ”

"So, you're starting to prepare to kill him?"

"Hmm."

In Zhang Li'an's narrative, he spent a lot of money to buy off a so-called hacker and asked him to help turn the monitoring of the often small theater, the monitoring of his corridors and entrances and exits, and Fu Huai's monitoring into a static picture.

The plan began at eleven o'clock that night.

In the darkness, he arrived at the small theater half an hour early and prepared his tools. Fu Huai arrived at the scene at half past eleven, was lured by Zhang Li'an to stand on the trap, and then killed the other party while he was not paying attention. When it was close to twelve o'clock, he used Fu Huai's mobile phone to log in to the hotel's communication software to communicate with Fu Huai's father to prove that Fu Huai did not die at twelve o'clock.

Looking at Zhang Li'an's smug face, Chen Mu didn't plan to demolish him for the time being, even if he couldn't find the phone, there were two huge loopholes in this plan, and sooner or later he would be arrested.

"Xiao Liu, let him confirm."

Liu Binglei took the printed confession to Zhang Li'an and signed and pressed his fingerprint.

The rest of the matter is Zhang Xiaotian's disappearance, which is the focus now.

Liu Binglei resumed the recording, and the second interrogation began.

Chen Mu was the first to make a difficulty, "When you were at home, did the words you say mean by finding someone to take Zhang Xiaotian away?" ”

"Yes, Zhang Chengjing deserves to be cut off!" Zhang Li'an grinned, "Officer Chen, you have to hurry, the person I am looking for is very nimble, I don't know when that little mongrel will be gone." ”

Since then, Zhang Li'an has not made any valuable confession to Chen Mu about this disappearance.

He seemed to really plan to see if the police could find the child before making a plan.

Chen Mu enlarged the map and marked it on the electronic screen.

At half past seven in the morning of July 3, Zhang Xiaotian's mother, Tian Lei, made it clear that she personally sent the child to school. But on the same day, when we went to see Zhang Chengjing, he called to verify that the child was not at school. ”

Yan Lingyun looked at the map, "That means that this abductor took the child away directly at the school gate?" ”

"Highly likely, but unlikely." Chen Mu scaled the picture and opened another folder, "This is the surveillance footage we took and entered the school gate for forty-eight hours, through a rough screening, at this time after the school started, there were no students leaving at all." In the rest of the year, no one came in and out of the school gate except for the school staff. So we need to check now whether anyone saw a suspicious person at the school gate that day and heard something suspicious. ”

Liu Binglei looked at the long string of numbers, "This is the rhythm of overtime again......"

"Yes, Xiao Liu, you just know." Lin Jialuo also straddled his shoulders weakly, "Boss Chen, when will I be able to take a vacation?" ”

"After the case is over, I will personally invite you to go to the team building."

"Okay."

Liu Binglei and Lin Jialuo happily went to work.

After Yan Lingyun saw that these two people were gone, he asked: "My job is not to watch monitoring." ”

"No, I want you to hire someone to appraise Zhang Li'an's spirit."

"You mean he's pretending to be crazy?"

From his behavior at home to his appearance in the interrogation room, he gradually went from calm to crazy, and there were traces of switching freely in the middle. I suspect he's preparing for the future. Chen Mu said his reasoning, "Zhang Li'an is cold-blooded, with his character, he will definitely think of a good trick for his future." ”

Yan Lingyun understood that Chen Mu was suspicious of this person in order to use mental illness to exonerate himself.

"Can I take a look at him first? Maybe we can find some breakthroughs. ”

Chen Mu shook his head and said calmly: "If we don't know what to fight with him, he will show flaws and be arrogant, but he will definitely not surrender completely." Therefore, you must find Zhang Xiaotian first, laugh at him, and beat him, so that you may be able to get a real confession. ”

Yan Lingyun said that he understood.

In this regard, Yan Lingyun also joined the team to visit and identify the suspect.

After two days of hard work, Liu Binglei finally got a good news and came to Chen Mu.

"Captain, look what I've found!"

Chen Mu got up from his tiredness, "What did you find?" ”

Liu Binglei excitedly showed the monitor in front of him.

"Look, the license plate number of this cleaning car is fake, it's a fake license plate number!"

Chen Mu also suddenly came to his senses, there is a situation that may not necessarily have something to do with fake things, but fake things must have a situation.

"I later called up the monitoring of the traffic police brigade, and finally found that he stopped in this small yard and took down a child!"

Liu Binglei magnified, intercepted, and then clear.

Got it!
