crime scene

Tang Songyuan was dumbfounded.

Xie Qian patted him on the shoulder and returned the same way.

"Officers, you can't..."

"You can go back to Dr. Tang. But keep your phone on and on call."

Xie Qian did not intend to detain Tang, Song and Yuan, after all, it was too far-fetched for a person with mental problems to identify.

There was still some time, Yang Wenxuan drove Tang Songyuan back to the clinic, and Xie Qian also took people with him, and went to the scene again.

Judging from the traces presented at the scene, there was really nothing missing, so he returned to the police station again at around 6 pm.

"Although the murderer has the means of beating, the three cases without exception were carried out in the posture of being a hindrance. There are more injuries on the back and lower body than on the front chest." Su Nian sat by the whiteboard, holding a pen in his hand. While listing doubts, it said, "He wants to express a certain emotion."

"Xiao Chu, don't you understand everything, analyze and analyze?" Xie Qian also walked over and sat beside Su Nian.

"I... If you really want to talk about analysis..." Chu Duanyu dragged his chin and pretended to be mysterious, "Do you know the characteristics of backwardness?"

Xie Qian licked his lips and replied, "I can't see the victim's face."

"Is there anything special about that face?" Su Nian asked.

"Let Jiang Panpan take out all the photos of the victim, and let's take a look together."

People in the entire office area got the photos and observed them in various weird poses and tricky angles.

It is normal to watch standing, sitting, turning around, and tilting your head to treat the cervical spine.

It was already very late at this time, with willows on the moon, dogs barking and cicadas singing, and the police officers in the office area began to check the photos repeatedly with bread and instant noodles in their mouths.

Su Nian said that she really didn't understand.

"I want to go back to the library to check the information."

"I'll take you back." Xie Qian put down the photo and rubbed his eyes, "It's so late, I don't worry about you going back alone."

"No, you didn't have much rest last night. It's not safe to drive at night."

"You don't think I'm... safe?" Xie Qian raised his eyebrows.

Su Nian couldn't resist him, so she nodded in agreement. Fortunately, it didn't take too long for the police station to go to the school, and it took more than 20 minutes to go back and forth.

"What time does your library open?" Xie Qian asked.

"At ten o'clock in the evening, you go back first, and you can pick me up at ten o'clock."

"Row."

When Xi Qian returned to the police station, a large number of people had collapsed. This kind of long-term low-difficulty work was the most tedious and tiresome. Several people had already started to complain of headaches.

"10 minutes, go out for a stroll, come back and continue."

With just this one sentence, more than half of the people rushed out, leaving behind some who were too lazy to move, or who were simply lazy.

Xie Qian sat down, picked up the photos and flipped through them one by one.

"Did you find anything?"

On the opposite side, Chu Duanyu, Zhang Tiantian, Yang Wenxuan and others shook their heads one by one, but Jiang Panpan held up his water glass and said, "I don't know if this is a discovery."

"It's okay, just tell me."

Jiang Panpan turned on the computer, "We have the fewest photos of the second victim, only the surveillance cameras in and around the train station. Captain, take a look... What do you think of this boy at first glance?"

Xie Qian took the computer and clicked on the video, Chu Duanyu also came over.

In the video, Yu Yangyi is getting off the train, looking around in confusion.

"A simple child is like white paper." Xie Qian replied.

Jiang Panpan nodded, "Then the third victim, Ruan Xingchen, I found a profile photo of him. Captain, take a look again. Does this angle look like someone? There is also a photo of the first victim with short hair."

"Why do I feel a bit like..." Chu Duanyu hesitated to speak.

"Call the police!" Xie Qian threw the photo on the table, full of anxiety.

He brought twenty people and four police cars to the school, and kept calling Su Nian along the way, hoping that nothing would happen to this kid again!

However, the phone only rang two or three times before prompting to shut down.

The sound of the police siren echoed on the street. The street was not blocked after 8 o'clock, but we could not let go of driving.

"The location has been determined. He is at the school. Captain, don't worry, don't worry!" Zhang Tiantian comforted.

"I'm not in a fucking hurry." Xie Qian replied, "Please tell me clearly whether the person is at school or the mobile phone is at school!"

"Even mobile phones can't run far away at school!" Zhang Yitian raised his voice, making himself look confident.

Did this kid have a bad life, being disappeared every now and then?

This is the third time, Xie Qian held his heart and gasped for breath.

Exhausted physically and mentally, he was in a hurry, but he didn't have the strength to worry anymore.

After being with Su Nian, his temper got better and better, he even forgot how to lose his temper.

Now he was sitting in the car, clenched his fists, and there was a fire in his heart, and he couldn't express it.

Fortunately, this time he knew that Su Nian might be there.

"Operation group, a group of ten people, A group is responsible for searching for Chen Nian'an within the school, intercepting all exits, B group searches for all possible hiding places, empty classrooms, libraries, the old dormitory building that has not been demolished!"

"Captain, where are we going?" Zhang Tiantian asked.

"In the old dormitory building, there is no one without monitoring, so it is convenient to do... a lot of things."

The first team acted quickly. After getting off the car, Qianqian went straight to the old dormitory building, which had not yet had time to be demolished.

If it was really Chen Nian'an, he would definitely choose Su Nian's original room.

If it was Chen Nian'an, he probably wouldn't hurt Su Nian... right?

Xie Qian thought so, and it came true again, it was not Su Nian but Chen Nian'an who yelled for help.

And it was Su Nian who was brought out.

Chen Nian'an held his neck and coughed violently, his face still in shock.

"Help, help...he, Su Nian...he wants to kill me, ahem..."

What exactly happened in this room during the half an hour that Xi Qian left?

Xi Qian gritted his teeth, "Dali, send him to the hospital first!"

"it is good."

Su Nian sat against the wall, his body trembling slightly, and he buried his face in his hands.

Xie Qian walked over, reached out to hug him in his arms, and patted him to comfort him.

Su Nian also obediently leaned into his arms, whispering, "Don't let him leave, he is..."

"I know."

"First... Let's take pictures to collect evidence..." Su Nian whispered.

He is afraid.

"Hey, take a picture and collect evidence."

"it is good…"

There was no sign of a fight in this room. When I rushed in, I only saw Chen Nian'an being pressed down by Su Nian, tightly pinching his neck.

There was also a rope covered in blood.

This is consistent with the wound on Su Nian's wrist.

Zhang Yitian came over, held up his SLR camera and patted Xiqian on the shoulder.

"Captain, I'll pat the wound on Su Nian's wrist and take a blood sample."

Su Nian obediently stretched out his hand, Zhang Yitian first took a picture of the wound, then Chu Duanyu brought the investigation box, took out a cotton swab, rubbed the wound, and put it in the evidence bag.

If you say that Su Nian went to kill people, Xie Qian would not believe it, and no one in your team would believe it.

But what he saw was that it was Su Nian who wanted to strangle Chen Nian'an to death.
