"Dean Wissen." Xu Sa was about to speak, when Wen Yan's voice sounded behind him.

"Officer Wen!" When Wei Sen faced Wen Yan, his attitude was obviously much better than Xu Sa's, and after the two exchanged pleasantries for a while, he turned his gaze to Xu Sa again, "Officer Xu, is there anything else that I need to cooperate with the investigation?" ”

Xu Sa took a picture of the patient's resume and prepared to take it to He Xingchen for him to investigate.

"Not for the time being, if there is any later, I will personally come to the door to ask." Xu Sa closed the medical record book and gave it back to Wei Sen, and glanced at him meaningfully, "Dean Wei Sen, the security in the city has not been very good recently, so you had better visit patients at home less at night, so as not to run into our serious crime team, which will be troublesome." ”

"I understand Captain Xu's kindness." Wei Sen helped his eyes, nodded at Xu Sa, and turned to leave.

Waiting for Wei Sen's back to disappear at the gate of the community, Xu Sa turned to look at Wen Yan and raised his eyebrows breathing, "Since when did your relationship with Wei Sen become so good?" ”

He vaguely remembered that after Wen Yan and Su Qing went to the hospital to investigate, the two of them also deliberately analyzed Wei Sen, but just now looking at Wen Yan and Wei Sen's greetings, the two were like long-term friends.

"What? Want to doubt me again? Wen Yan glanced at him mockingly, "Dean Weisen is a well-known scholar in the field of psychology, what's wrong with me knowing him very well?" ”

Wen Yan's tone can be said to be very rushed, and this tone is something that Wen Yan would never use before.

"Wen Yan, can't you talk well?" Xu Sa frowned, glanced at the direction of the unit building, and said quickly while Su Tong hadn't come down yet, "Do you know how worried Su Tong is about you!" ”

"Don't bother your worries." Wen Yan sneered, "If you have time to worry about me, you might as well spend your time investigating the case, I just want to find Su Qing's body as soon as possible!" ”

"You ......" Xu Sa was a little angry, and just as he wanted to speak, he was interrupted by Li Hua who ran over from the side.

Li Hua didn't notice the-for-tat atmosphere between Wen Yan and Xu Sa at all, stuck between the two, his face changed blue and white for a while, and only after half a sound did he hold back a sentence, "Our people have found another corpse......

The expressions on Wen Yan and Xu Sa's faces changed at the same time, and they listened to Li Hua continue to say, "The deceased is the second victim of the nail case, and he was also found dead in a fish tank by his family, with a knife cut all over his body, and we guess that the crime scene is similar to this side......"

After speaking, Li Hua cautiously glanced at Xu Sa, there were two homicides within an hour, and the victims were all in the same case before, and no one believed it if the murderer was not the same person.

But this also shows a very serious problem, that is, the behavior pattern of the murderer is changing, and the victims of the previous nail cases are all in danger!

"You and Chen Hui stay here, I'll go over there now." Xu Sa took a deep breath and called Su Tong to ask her to go downstairs.

Su Tong was also very surprised to learn that there was another case, and his first reaction was whether it was a misunderstanding, but the situation at the scene was similar.

But when Xu Sa told her the identity of the deceased, she knew that this could not be a misunderstanding.

Xu Sa took Su Tong to another crime scene, this time Wen Yan did not go with them, but offered to stay at the scene of the first case with Li Hua and them.

"Su Tong, do you think this case is likely to turn into a serial murder case?" In the car, Xu Sa was silent for a long time, and opened his mouth a little heavily.

According to the previous murderer's crime pattern, he has basically guessed that the murderer's target is all the victims in the previous nail case.

But speculation is always just speculation, so far there is no more evidence to support his speculation, and he naturally can't convince Sun Ju, so he can only turn to Su Tong for help.

"Not a possibility, but a certainty." Su Tong looked straight ahead, his face was very serious, "Two cases, the same death scene, the same victim group, according to your words, there will be no such coincidence in the world." Therefore, this case is already a serial murder case. Xu Sa, you need to explain the situation to the Sun Bureau immediately. ”

Because of the nature of quiet, the scope of the investigation will also be different. In an extremely cruel and vicious serial murder case like this, in the process of investigation, in order to solve the case as soon as possible, they will unite multiple departments to work together, which requires Sun Bureau to contact and arrange.

"Is that really the case......" Xu Sa sighed a little tiredly, "When are these cases going to be the end......

Although this is what he does, he also hopes that one day his team will have no cases to handle.

"Actually, I'm more worried about another issue." Su Tong glanced at Xu Sa beside him, and said with some uncertainty, "You say, if Su Qing's body is in the hands of the murderer, according to his previous crime pattern, what will the other party do?" ”

The murderer just pulled out Su Qing's nails at first, just like those victims. But now, the murderer's behavior has escalated, so what will he do to Su Qing's corpse?

"Or is Su Qing's body likely a stimulus to change the murderer's behavior?"

Xu Sa's mind flashed, "You mean that the murderer may have a very close relationship with Su Qing, but we have a person who doesn't know about his existence?" ”

And such a person stole Su Qing's corpse, and because Su Qing's corpse changed his behavior pattern, it all made sense.

"However, didn't Su Qing just come back from abroad when she was transferred to the serious crime team?" Xu Sa thought for a while, "Moreover, at that time, I listened to the tone of Sun Ju, as if Su Qing had just finished handling a case and was seconded back by our people. ”

"I don't know." Su Tong shook her head blankly, and the idea just now just suddenly popped out of her mind.

So far, there are no clues or evidence to support the conjecture in her head. She had never encountered a case, which made it difficult for her to start, and when she thought of this, Su Tong not only felt that the burden on her shoulders was a little heavier.

"It's okay, we'll investigate slowly." Seeing her uneasy mood, Xu Sa took her hand and put it on her lips and kissed it, "The more cases the murderer commits, the more clues he will show, I hope we can find out when the second crime scene occurs." ”

Su Tong nodded worriedly and did not answer.
