"You don't have to say it, I understand." Xu Sa gently put down Su Tong's hand, and his tone was so indifferent that it stabbed Su Tong's heart.

Su Tong looked at Xu Sa like this and turned away. She didn't catch up, she couldn't tell why.

When Su Tong returned to the ward, he was told by the nurse that Xu Sa had been discharged.

I didn't give him the answer I wanted today, which probably really made him uncomfortable.

Su Tong drove to the door of Xu Sa's house, she hesitated to go in, but what could she say after entering?

Time passed like this, when Xu Sa, who was at home, was about to draw the curtains, he found the car outside the door that was familiar with the license plate number, he only paused, but still closed the curtains, but he didn't pull it dead, and there was still a seam.

One in the house and one in the car. No one wanted to get closer.

Su Tong was looking at the confession document of the case in the car at the moment, and looked at his watch, it was already half past eleven in the evening.

Seeing that the light was still on in the window of Xu Sa's room, she continued to look down at the documents.

The mobile phone rang suddenly, and it was the duty room phone of the police station.

"Officer Su, Bureau Sun said that there has been a new change in the case, and I want you to go to the location of the crime on the outskirts of Heng'an immediately, and the location has been sent to you by Officer He." There was an urgent voice on the other end of the line.

"Okay, I got it. I'll go right away. As he was talking on the phone, a message rang. After Su Tong hung up the phone, he clicked on the location sent by He Xingchen and set off immediately.

At the same time, Xu Sa also quickly called Sun Ju to ask him if he could go back to work at the police station immediately tomorrow, Sun Ju rejected his request, and said that he would return to the police station tomorrow to hand over his gun, and by the way, he took all the annual leave in the past few years.

After hanging up the phone, Xu Sa found that the car outside the door was also gone, and his heart suddenly fell to the ground.

Not long after the large army arrived at the scene of the crime, Su Tong also arrived.

Old Chen beckoned Su Tong over, only to see the body of a little boy lying in the middle of a big pit. There was also a letter pressed upright under his hand.

"I'm afraid I'm going to trouble Shirley again this time for identity confirmation." Su Tong said worriedly.

"No need this time, the identity can be confirmed." He Xingchen was holding the computer, and the trace inspector in charge of shooting was uploading pictures to He Xingchen's computer.

"How?" Su Tong looked at He Xingchen and asked.

"I asked Shirley to borrow their agency's facial recognition software, and Shirley said it was 90 percent accurate. Just now I added the photos to this software, and I screened all the children's registration and visit data in China, and I just need to wait for the statistics of the five senses and various places. He Xingchen said excitedly.

"So, how long will it take?" Old Chen asked curiously.

"This..."He Xingchen's computer made a dinging sound, "I found it, but..."

He Xingchen handed the search results to Su Tong and Chen Lao.

The computer reads, "Yang Jianming, male, eleven years old, entered the orphanage adoption system at the age of two. ”

"Which orphanage?" When Su Tong heard the word orphanage, he had an ominous premonition.

"I didn't find it," He Xingchen shook his head, "But there is only one reason why I haven't found it, and that is that the orphanage has closed down, so the orphans have directly entered the adoption system, and the source has not been found." ”

The forensic officer opened the letter into the evidence bag and handed it to Su Tong.

"I think I know which orphanage it is." After Su Tong quickly browsed it, he said something with a complicated expression.

"What's wrong?" Zhou Li took the letter directly.

It reads: "Greetings, dear officers. I am the perpetrator of this serial murder of children, and given your limited abilities, you are unable to trace my identity.

Therefore, I take the initiative to make a deal with you, as long as I release my dean, Shang Minghua, I am willing to surrender. But if I don't get Shang Minghua's release notice by six o'clock tomorrow afternoon, I will kill one person every day until you are willing to release me or catch me. ”

"What should I do?" Zhou Li quickly read the threatening letter, resisting the urge to tear it apart.

"Are we going in the wrong direction?" Zhou Li asked in a low voice.

"We didn't make a mistake!" It was rare for Su Tong to speak with He Xingchen in such unison.

"But..."Zhou Li couldn't understand it at all, the murderer's letter was very clear.

"This murderer claims to be a beginner, and keeps threatening us to release Shang Minghua, but this murderer's methods are more than a star and a half compared to Shang Minghua, and he doesn't need to learn Shang Minghua at all." Su Tong said his opinion.

"But what is said above..."Zhou Li was not worried about whether this murderer was Shang Minghua's apprentice, but that she was afraid that the other party would really kill someone a day.

"That's what I can't figure out the most." Su Tong patted his forehead, and he clearly had no clue, and now it has only been a few hours since the murderer turned against him.

Suddenly, Su Tong said inquiringly: "You say, will the murderer deliberately disturb our sight, so he will arrange it like this." If there is no accident, we will be able to find a breakthrough in Zhong Zhixin's family tomorrow, and suddenly a case will point the finger in a completely new direction. ”

"It's also possible that the murderer couldn't read his message when he saw us in the wrong direction, and like that Shang Minghua, he felt that his artwork had been destroyed before he would kill again." Zhou Li quickly retorted.

In fact, what Zhou Li said also makes sense, she can't tell the authenticity of this letter, so she can't confirm what the murderer's thoughts are.

"Did Elder Chen find anything?" Su Tong decided not to dwell on the murderer's psychological reasoning for the time being, and focused on the existing real evidence.

"The deceased, like the previous corpses, was cut out by the living body, and based on the stiffness of the corpse and the temperature of the liver, it can be inferred that the child died about four to five hours ago." Elder Chen told Su Tong about the preliminary examination results.

"Are there any other scars on your body?" Su Tong looked at the corpse that was being removed from the pit.

"Speaking of which, I have made a new discovery." Chen Lao took off his gloves and mask, "The chest cavity of the previous victims was opened and directly hearted, and the surgical process was very clever.

But from the last male corpse and the most recent female corpse, including this one tonight, the method of opening the chest cavity to take the heart seems to have changed, and it has become careless and rude. ”

After Chen Lao finished speaking, he beckoned the assistant to carry the body back to dissect it.

Su Tong, Zhou Li and He Xingchen stood together and thought, the last body killed was Zhong Zhixin, the only female corpse was Zhong Yuehong, and the latest male corpse was Yang Jianming.

Zhong Zhixin and Zhong Yuehong are related, they know it, but what does Yang Jianming have to do with Zhong Zhixin and Zhong Yuehong?
