February 17 at 7:50 a.m

As soon as he entered the office, Zhou Ning turned on the computer.

Inside the mailbox, there were four unread emails, with a yellow warning sign on them, which was a specific icon for internal urgent mail, and Zhou Ning nervously clicked it.

1. The DNA information of two people was collected on the murder weapon, namely the No. 1 male and the No. 2 female who sent the samples for testing, and the blood samples collected on the blood fingerprints belonged to the No. 1 male DNA;

2. There is a occult blood reaction in the urine, and the No. 1 male DNA is extracted;

3. In samples 35-174, No. 1 male and No. 2 female blood were found, respectively.

In samples 4 and 3-34, there was only male blood No. 1;

1. Pajama samples: two samples of blood were extracted from the cut marks of the clothes, No. 1 male blood and No. 2 female urine were extracted from the pants;

After reading the report, Zhou Ning exhaled.

However, the system seemed to be silent, the countdown was still jumping, and there was no intention of stopping at all, Zhou Ning blinked, a little puzzled, the murderer was Zhang Xin, this is already a sure thing, is the chain of evidence incomplete?

At this time, on the large transparent screen, the contents of these reports, as well as the various processes analyzed by Zhou Ning, were all displayed, but there was a line of small red words at the bottom.

Tips: Please note that due to insufficient evidence in this case, a confession from the criminal suspect is required before the task can be submitted, and the binder is reminded that there are still 50:50 hours left in the task!

Zhou Ning made a mistake, it's useless to complain now, the system won't reason with you, or negotiate, you have to complete the task as required, but that Zhang Xin is still pretending to be crazy, how to get this?

At this time, Liu Yongxin pushed the door in, saw Zhou Ning, blinked and asked:

"You kid early in the morning, why do you have a lawsuit, is there a problem with the report?"

Zhou Ning shook his head.

"It's okay to report."

"Then why do you have that expression? By the way, don't you tell me what the hell are you secretly doing against the law? God has been hiding mysteries from me for a day. ”

Zhou Ning smiled embarrassedly and grabbed Liu Yongxin's arm.

"Master, don't worry, if you say it, there will be no mystery, rest assured that it is definitely not a violation of law and discipline, that is, this trick is a little damaged, let's call Xu Da, go to the Eighth Courtyard to have a look, I think it's time to check the results."

The test report just now made it very clear that Wen Haicheng's wound only had his bloodstains, while Zhang Xin's wound had the common blood stains of the two, the blood on her pants was also Wen Haicheng's, and there were fingerprints and blood stains on the murder weapon.

Now the evidence points to Zhang Xin, but in such a case, relying on these characterizations alone is still a bit thin, I think at least let Zhang Xin speak, pretending to be crazy cannot escape legal sanctions, and even a heavy sentence, we have to force her to stop pretending to be crazy, and we have to get a killer weapon for this. ”

"Wait, there's a killer feature, what kind of structure is in your brain, do you have one set of another?"

Zhou Ning was a little embarrassed, he couldn't say that he was forced by the system, there was not much time left in the countdown, he had to work harder, otherwise he would really be struck by lightning!

Zhou Ning took out his mobile phone and dialed Da Zhao's mobile phone.

"Are you here?"

"Just got downstairs, should you go now?"

"You wait for me, I'll go downstairs now, the camera applied?"

"Don't worry, absolutely professional-level camera, don't ink, hurry downstairs."

Zhou Ning grabbed his down jacket and ran outside, Liu Yongxin didn't ask this time, watched Zhou Ning leave, just leaned on the door frame and looked at Zhou Ning's figure.

As if hearing the sound of running, Xu Dayuan walked out from next door, and saw Liu Yongxin looking at the stairs like this, with a smile and a gossip on his face.

"What are you laughing at? What's the matter, your son has a girlfriend? ”

Liu Yongxin glanced blankly.

"Look at my apprentice, I'm happy, why are you envious?"

Xu Dayuan smiled.

"Okay, this sentence scares me to death, I can't envy it, but why did your apprentice go?"

Liu Yongxin shook his head.

"Listening to what Da Zhao meant, it seems that he walked with professional camera equipment, I don't know what to do, but don't worry, it will definitely have a role in promoting the case, I am absolutely sure of this, this kid is too similar to me when I was young!"

"You didn't ask them why they went?"

Liu Yongxin laughed hesitantly and waved his hand at Xu Dayuan.

"Secret!"

......

15:30

Office of a Neurologist at the Eighth Hospital.

In the corner of this place, the computer has been placed, and on it is the picture of a ward, there are two beds in the ward, Zhang Xin is lying on the bed by the window, clutching the quilt, shaking his head and biting constantly.

A doctor stood beside Xu Dayuan, smiling helplessly.

"The nurse who hung water in the morning, spilled the food on the bed at noon, and by the way, I was still squatting on the bed to urinate yesterday, this ward is dirtier than the bathroom, I said Xu Da, what are you going to do?"

Xu Dayuan patted the doctor on the shoulder and said comfortingly:

"Bear with me, you have consulted her, right, is she mentally fine?"

"To be honest, I can't tell if it's pretending or really having a mental disorder, but she's always been in such a noisy state, it's still relatively rare, we want to do brainwave monitoring for her, but we can't do it at all, we can't cooperate!

So, I can't tell if she is really sick or pretending, but judging from my experience, she does look like she is pretending. ”

Hearing what the doctor said, Xu Dayuan also became more confident.

"Director Liu will send a nurse to push out our person from the hospital bed."

Director Liu went out to arrange, Liu Yongxin looked stunned and poked Zhou Ning.

"How long do you kid want to hide from me, what are you doing here, am I still your master?"

Zhou Ning clasped his hands together and said with a smile:

"Master, I didn't want to lie to you, isn't this Xu Da's big heart and wants to joke with you, take a closer look, is the person in bed No. 1 familiar?"

When Liu Yongxin heard this, he approached the monitoring and looked surprised when he took a closer look.

"Isn't this Zhang Wanshun of the criminal police team?"

Xu Dayuan laughed twice.

"What's the matter with Forensic Doctor Liu, this disguise is okay, your apprentice's idea is to let our people disguise themselves as patients, and then change Zhang Xin to the ordinary ward where they are, and then monitor and observe at this time, so as to judge whether she is pretending to be crazy."

Liu Yongxin snorted and kept shaking his head.

"It's a bit of a loss, but it seems to work."

Seeing that Zhou Ning and Liu Yongxin were both looking at the door, Xu Dayuan was stunned for a moment, he also turned his head, and saw Zhang Wanshun sitting in a wheelchair, Xu Dayuan gritted his back molars, let himself hold back a smile, and nodded solemnly.

"Xiao Zhang has worked hard, how is the situation?"

Zhang Wanshun is a very thin criminal policeman, it is estimated that he was chosen because of his height and appearance, after all, he buttoned up his wig and put on underwear, there was no sense of disobedience at all, and he looked like an authentic Aunt Qindao.

"Xu Da, if you don't pick me up again, I can't help but beat people."

Xu Dayuan slapped Zhang Wanshun on the shoulder, Zhang Wanshun directly ripped off the wig, and the aggrieved were about to cry.

"Beat me, I won't go, this Zhang Xin is a madman."

"Are you sure?"

Zhang Wanshun snorted twice, and then said:

"I just complained, Zhang Xin was pretending to be crazy, after turning off the lights at night, she was honest for a while, secretly observing whether I was asleep, after twelve o'clock, she began to gnaw on the steamed buns hidden under the pillow, although she urinated on the bed during the day, but she would never pee on the bed at night."

Xu Dayuan breathed a sigh of relief and smiled at Zhang Wanshun.

"You go and rest, hard work! Da Zhao will monitor the time that Zhang Wanshun said, and see if it has been filmed? ”

When Zhang Wanshun heard this, he grinned, rushed to the sink in the doctor's office, and washed the things on his face.

Although the lights are turned off, part of the door of the hospital is glass, just to observe the patient's condition, so the light in the corridor is enough to see the situation in the room.

Sure enough, at 12:34, Zhang Xin got up, came to Zhang Wanshun's bedside, and deliberately clapped his hands in his ear.

Director Liu followed and tapped the table with his fingers.

"You don't need to do any EEG, this person is just pretending to be crazy, his thinking is very clear, I can give you a diagnosis in a while, of course, if it is transferred to the procuratorate, there will be a mental evaluation in the future, and there is an appraisal center in this city bureau that can do it."

"Thank you, I've caused trouble to your department, the little nurse who was beaten, help me calm down, and then I want a pennant to have a pennant, and I want a bonus to apply here, what do you think?"

"Come less, I'll be thankful for taking people away quickly."

Xu Dayuan waved his hand, and the smile on his face was also put away.

"Let's go, Forensic Doctor Liu and Zhou Xiaozhou will follow together, and your secret weapon should also be revealed!"
