Su Tong frowned faintly, obviously, she was also quite puzzled by the question raised by Xu Sa.

What caused the change in the murderer's mentality and emotions, or maybe this is the murderer's real way of committing the crime, and the previous time to pull out his nails was just a lock for the victim.

"Chen Hui, Li Hua, you two bring the victim's boyfriend back to the serious crime team and ask again." Xu Sa pondered for a moment and began to give orders to arrange everyone's work, "Zhou Li and He Xingchen, the two of you go and retrieve the surveillance video of the community to see if you can find out what kind of strangers have entered and left this building tonight." ”

"Su Tong, Wen Yan, you and I will go back to the police station and wait for Elder Chen's autopsy report." When he said the last sentence, Xu Sa glanced at Wen Yan lightly, and saw Wen Yan staring at the bathtub without saying a word, and he didn't know what he was thinking.

"Wait, I'd like to see the crime scene again." Su Tong hesitated to speak, she always felt that there were still some things in this place that she had overlooked.

"Okay, I'll wait for you outside, something will call me." Xu Sa took out the mobile phone that had been ringing for a long time in his pocket as he walked.

The people piled up at the door of the bathroom gradually dispersed, and Su Tong was the only one left in the bathroom, and the suffocating smell of blood became heavier, even if she was wearing a mask, she could smell it very clearly.

With the passage of time, the blood stains on the wall showed different shades, and Su Tong silently remembered those traces in his heart, simulating the scene of the crime in his mind.

On the balcony of the living room, Xu Sa connected the mobile phone with a heavy heart, and before he could speak, Sun Ju's burst came from the phone, "Xu Sa, what did you tell me about this case!" As long as it is handed over to you, I promise to give me an explanation within three days! It's good now, I'll hand over the case to you, and as a result, in less than a day, the case escalated to a homicide case! ”

"Also, I heard that you have locked up the suspect before, why didn't you arrest the suspect in the first place!" Sun Ju excitedly walked back and forth in the office, "Do you know that the escalation of this case is probably caused by your failure to arrest the suspect in time!" ”

When the news reaches the media, I don't know how much of a storm it will set off!

"Sun Ju, we have already found out about the suspect." Xu Sa breathed a sigh of relief and spoke patiently, "It's all a misunderstanding, and during the time period when the murder occurred, the suspect didn't have time to commit the crime at all." ”

He knew that Sun Ju would know about Wen Yan's time sooner or later, it was just a matter of time.

"Misunderstanding!" Sun Ju almost jumped up when he heard Xu Sa's words, "The person who has always spoken to me with evidence is now telling me that it was a misunderstanding!" Xu Sa, do you still want me to teach you this? The suspect didn't have the time to commit the crime, so there is a good chance that he has some accomplices, did you forget about Pete's case so quickly! ”

In Pete's case, they completely ignored the existence of accomplices in the course of their investigation.

Xu Sa was stunned, and was speechless for the first time by Sun Ju.

"Xu Sa, I don't care what method you use, within three days, I want to see the murderer." Sun Ju suppressed the emotions in his heart, gritted his teeth and spoke, "Otherwise, you will help me open the press conference when the time comes!" ”

After speaking, he hung up the phone with a "bang".

Xu Sa sighed with a headache, Sun Ju was under a lot of pressure during this time, and he also understood it. But this case, if the reason for this case is really found out within three days, he thinks it is very big, after all, from the beginning, all the evidence pointed to no one other than Wen Yan.

Putting the phone in his pocket, he was about to go back to the bathroom to call Su Tong out, and in the process of turning around, he saw a familiar figure downstairs.

The victim's house is on the second floor, and there are few shelters on the balcony of the living room, and the line of sight is very open, so Xu Sa can see the other party clearly at a glance.

He paused only slightly, then immediately turned and ran downstairs, rushing towards the man.

"Dr. Wiesen! How did you end up here! Xu Sa looked at the smiling middle-aged man in front of him, and his heart was full of vigilance.

He still remembered the bad feeling he had when he first met Wei Sen, although Su Tong always said that it was his delusion, but he always felt that a series of cases he had encountered recently had a magical connection with Wei Sen.

"Captain Xu!" Visen blinked in surprise, "What a coincidence, I didn't expect to meet you here." I came to visit a patient who had been discharged from the hospital, and I happened to see a lot of police cars gathered here, and I wondered if something was wrong, so I met you, Officer Xu! ”

As he spoke, he glanced in the direction of the upstairs again, "So, Officer Xu, is there a death in this building?" ”

Xu Sa didn't answer his question, only looked at him inquiringly.

"Ah, look at me, these questions shouldn't be asked casually." Wei Sen didn't mind, patted the back of his head, and found a staircase for both of them, "In this case, I won't disturb Captain Xu's work, and we will have tea together next time I have a chance." ”

"Wait!" Xu Sa stopped Wei Sen, who was about to turn around and leave, "Dean Wei Sen, which patient are you here to see, can you tell me?" ”

Wei Sen's back paused slightly, and he turned back puzzled, "Captain Xu, what are you asking for?" My patient has now been discharged from the hospital and has his own privacy, and I can leave you without an investigation order. ”

Xu Sa hooked the corner of his lips carelessly, took out a cigarette from his pocket, put it in his lips and didn't light it, and said lightly, "I now suspect that the murder that happened above has something to do with the mentally ill, if Dean Weisen needs an investigation order, I can apply for it right now." Well, I'll have to ask Dean Wesson to wait here for me. ”

At this time, what kind of discharged patients are coming to visit their homes? Xu Sa sneered, is it really for him to be a policeman for so many years?

Wei Sen's face changed, and he spoke unwillingly, "Okay, I said that." ”

He took out a folder from his briefcase, "This is the information of the patient I visited this time, because this patient's situation is special, and he can only be visited at night, so I came a little late." ”

"Captain Xu, if you want to investigate this patient of mine, please be sure that I am also present, I don't want my recovered patient to be stimulated in any way." Wei Sen's words are very sincere, and people can't find the slightest fault.
