"Why do you say that!!" Lin Weibin went violently, and actually rushed up and wanted to pounce on Xu Sa.

Chen Hui hurriedly pushed Lin Weibin back to his seat. "You pay attention to me!"

"You're not me! Why do you say that? After Lin Weibin was pushed back by Chen Hui, he still pointed at Xu Sa angrily and said.

"Just because I'm a policeman, you're an unlaw-abiding citizen, okay, you said you killed Song Yanjiang, but I don't believe it. For the sake of fairness, I will still detain you for 48 hours, and if we do not find conclusive evidence, we will charge you.

But why should I bother to explain it to you, you won't understand it anyway. Xu Sa patted Chen Hui's shoulder as he spoke.

Lin Weibin heard that Xu Sa was trying to insult his professionalism again, and he was about to go crazy.

Xu Sa didn't give him that chance, but quickly exited the interrogation room, and Chen Hui also withdrew soon after.

"Turn off the circulating air conditioning system." Su Tong stared at Lin Weibin, who was still exuding residual anger in his seat.

Slowly, Lin Weibin kept wiping his sweat, and he casually pulled out the paper in the drawer box that was placed on the table.

But wiping his sweat all the time didn't calm him down.

"How's he doing?" Xu Sa and Chen Hui walked into the monitoring room and asked.

"In the fifteen minutes since you left, he's looked at his watch at least twenty times and wiped his sweat more than six times." Su Tong's eyes stared at Lin Weibin.

"The train is still an hour away, isn't it?" Su Tong asked by the way.

"We have notified the train station, and as soon as the suspect enters the station, he will be detained and immediately escorted to our police station." Chen Hui replied.

"Oh," Su Tong stroked his chin with one hand. "Chen Hui, you find someone to replace the trash can, and the paper towels and empty water bottles in it will be sent to the forensic evidence immediately."

"What do you think?" Xu Sa was silent for a long time and asked Su Tong this.

"Just like you." Su Tong frowned, his eyes full of worry.

"Huh?" Chen Hui didn't understand, what kind of fairy quarrel was this?

When the cleaner opened the door and walked into the interrogation room, Lin Weibin's whole body was in a state of fear, but when he found that it was not Xu Sa who walked in, but the cleaner, he was obviously relieved, and unconsciously raised his hand to look at the time, his eyes were full of unease.

Su Tong didn't let go of his every expression.

"I found it." He Xingchen excitedly opened the door of the monitoring room at this time.

"What did you find?" Chen Hui asked excitedly.

"I know why Lin Weibin came to confess." The joy in He Xingchen's eyes couldn't help himself, "It turns out that this Luo Su'e and Lin Weibin are-"

"It's mother and son."

"It's mother and son."

Xu Sa and Su Tong said at the same time.

He Xingchen looked at the two of them in surprise, "Boss, how do you know?"

"He's been looking at his watch, and now it's less than thirty minutes before the train leaves, and the closer he gets to that time, the more nervous he gets." Su Tong looked at the restless Lin Weibin and said calmly.

"We didn't find any traces of him at the scene of the crime, Changtong Electronic Technology has withdrawn the complaint against him, and he obviously won't have any problems.

In such a situation, he is willing to fight to lose his future and the freedom of the rest of his life to confess, which shows that he knows this murderer and is very important. Su Tong said slowly, but his eyes hadn't left Lin Weibin, who had secretly looked at his watch again.

Xu Sa's mobile phone vibrated at this time, and he turned on the phone, "Luo Su'e has been caught, and it will take half an hour to escort him over." ”

"Let them not rush over first, and go to the forensic examination first to do the paternity test before sending it over." Su Tong hurriedly said.

"Hmm." Xu Sa responded to Su Tong softly, and replied to something with a text message.

"We'll try him when that time is over." Su Tong supported the edge of the console with two hands.

He Xingchen was a little disappointed when he saw that what he was about to say had been robbed.

"How did you find out?" Chen Hui asked curiously.

Speaking of this, He Xingchen still said with some pride: "I found out that Luo Su'e had submitted a transfer of household registration a year ago and wanted to move her household registration to our city, when she had not yet worked in the deceased's home.

However, she filled in Lin Weibin's name in the column of permanent family members in the city, and in the relationship column at the back, she filled in mother and son. He Xingchen turned the computer screen to Chen Hui like a treasure.

But because Lin Weibin was only an intern at the time, he had no regular source of income, and he did not meet the qualifications for moving his household registration, so this application was rejected.

Then a month later, Luo Su'e became Song Yanjiang's family part-time worker, specializing in helping Song Yanjiang clean all the properties under his name. ”

He Xingchen glanced at Xu Sa, inexplicably a little weak-hearted, he was still very impatient to think that Luo Su'e was an unimportant discoverer.

Now it turns out that the person who found it is the murderer of this case.

Fortunately, Xu Sa and Su Tong have always insisted on investigating, otherwise, wouldn't the murderer have escaped.

"Probably even Song Yanjiang himself didn't know that Lin Weibin put his mother next to him." Su Tong shook his head slightly.

"Oh, I found something in the deceased's phone before, maybe it will come in handy." He Xingchen suddenly thought of something, and then quickly searched for it.

"It's this." He Xingchen opened the data.

Su Tong and Xu Sa looked at each other seriously, and after a long time, the two glanced at each other, and Su Tong asked with a complicated expression: "Do you guess Lin Weibin knows about this?"

"I shouldn't know, if I knew, I think Song Yanjiang would have died in the hands of Lin Weibin before he had time to make him a scapegoat." Xu Sa shook his head slightly.

"Don't talk about this matter with Lin Weibin first, when the case is closed, let him deal with it himself, Song Yanjiang is dead now, who else can he find for revenge?" Su Tong sighed.

The atmosphere in the control room was heavy at one point.

On the contrary, the closer to the time when the train departed, Lin Weibin slowly relaxed, although he did not reduce the frequency of looking at the time, but he could relax a little and lean on the back of the chair.

Half an hour had passed since the train departed, and Xu Sa belatedly walked into the interrogation room.

Lin Weibin has changed his appearance, he doesn't have such a feeling of eagerness and anxiety, and he looks at Xu Sa with a certain sense of completing his mission.

"I've kept you waiting, Mr. Lin" Xu Sa saw it and was not in a hurry to debunk his little tricks.

"I really don't understand you, why haven't you formally charged me when I've already pleaded guilty?" Lin Weibin said impatiently.
