Zhou Ning nodded.

"People can test it when they come, and I'll prepare things."

After saying that, Zhou Ning didn't stop, walked quickly, Xu Dayuan looked at Zhou Ning's back, and the small half of the pancake fruit in his hand was stuffed directly into his mouth.

Gobbled it up, and then waved at everyone.

"Okay, call Zhenshan out for dinner, get me the monitoring and everything, Chunyang, we will meet the two brothers together in a while, starting with Wang Guangren, but before that, call Wang Guangren's unit, I want to know all the details of his unit, by the way, and the daughter-in-law of their brothers, it's not divorced to check where is the person."

After a while, Zhou Ning went and returned, followed by the swaying Da Zhao.

Da Zhao smiled and saw Xu Dayuan and them from a distance, constantly waving his hand, and lifting the bag he was carrying in his other hand, which seemed to be not light.

"I said everyone, wait a minute, don't worry, get something."

Saying that, Da Zhao handed over the bag, Xu Dayuan coughed, Xiao Bai quickly took over, opened it and took a look, there were two wrenches inside, as well as a wooden screwdriver and some screws, Xiao Bai didn't ask stupidly, and stood behind Xu Dayuan.

Tao Zhenshan rinsed his mouth, followed and walked over, smiling at Zhou Ning.

"Hardship Zhou forensics, I will meet this kid with Xu Da, we need to determine whether he is left-handed or right-handed, right?"

Zhou Ning nodded.

"Yes."

Xu Dayuan pointed to the observation room next door and raised his chin towards Zhou Ning.

"Go to the observation room and see."

Bai Ruixin bared his teeth and leaned over, he was indeed a little heartless.

"No way, who let Forensic Doctor Zhou be the mascot, hurry up and take place, let me say goodbye and be happy!"

Bang, Bai Ruixin's back of the neck was slapped, and Xu Dayuan was already glaring.

"Don't talk nonsense, bring things in with us, put away all the jokes for me, if you can't do it, I'll change people now, will I use Zhou Xiaozhou as a mascot? Shut up if you can't speak! ”

Seeing that Xu Dayuan was on fire, Bai Ruixin was startled, quickly shut up, followed behind Xu Dayuan and He Chunyang, pushed the door and entered the interrogation room.

Zhou Ning and the others also hurried to the observation room, there were a lot of headphones prepared here, Zhou Ning and Da Zhao stood on one side, each wearing headphones.

In fact, Zhou Ning understands that murderers like Wang Guangren, who have killed more than a dozen people, are all psychopaths and emotionally numb people, but if they have a little sympathy or kindness, they will not do such a tragic thing.

That's why He Chunyang and the others took turns to do missions, and Xu Dayuan didn't go on the field to interrogate, and the reason for boiling eagles is that it may be fatigue tactics at the beginning, and it is to see who is psychologically stronger in the later stage.

interrogated again like this, as soon as he entered, the aura was different, and the sense of oppression given to the suspect was also different.

Sure enough, as soon as several people entered the interrogation room, Wang Guangren couldn't help but look up at Xu Dayuan.

Glancing at it, he quickly staggered his gaze.

The clerk sat down, He Chunyang opened the record book, Xu Dayuan walked to the interrogation chair, pulled the handcuffs on Wang Guangren's hand, and then said loudly:

"Let him loosen the handcuffs and give him something to test, and then turn the screws, right?"

As he spoke, Bai Ruixin walked closer, his face was tense and blue, he looked really serious enough, and he added a lot of points, opened a handcuff, and put the wooden board, screwdriver, screw, and wrench in front of Wang Guangren one by one.

Then, raise the camera in your hand.

"Let's do two actions first, the first one is to screw the screws on the wooden board with a screwdriver, just complete the two screws, and then open the control valve of the wrench, we are a little faster."

Wang Guangren's eyes were full of doubts, I don't know which one this is doing?

The two newcomers, he saw them yesterday, this middle-aged policeman looked like their leader, but after being interrogated for almost 24 hours, why did he suddenly change his method, not asking about things, and screwing when he came up?

Although he was puzzled, Wang Guangren didn't understand what could be connected with the eucalyptus, paused for a few seconds, and then grabbed the screwdriver and began to screw and wrench.

After doing Bai Ruixin's prescribed actions, Bai Ruixin also completed the recording work, and then walked over, put on gloves, put everything in a bag, and carried it out, as if the interrogation here had nothing to do with him.

Zhou Ning saw the end and breathed a sigh of relief, people's subconscious movements are the most intuitive, when they pick up things and screw them, they are right-handed, he is a typical right-handed, and the scar on the skull of the deceased is anastomosis.

This series of operations, especially wearing gloves in the back, made Wang Guangren even more confused.

Before his gaze was withdrawn, He Chunyang had already put the handcuffs on him, Wang Guangren hurriedly lowered his gaze, obviously he felt that the action just now had exposed too much of his thoughts.

Xu Dayuan smiled, the evidence of this eucalyptus at this time was conclusive, but he had some doubts among the murderers of the deceased of the fifth deceased, but this had no effect on Wang Guangren.

After all, nineteen or eighteen dead people, for him, it was only a difference in quantity.

Leaning on the table, Xu Dayuan hugged his arms and began to say:

"My name is Xu Dayuan, the captain of a large team of the Qindao City Criminal Police Detachment, we met yesterday, what I came to represent, you should be able to guess some, don't play dumb riddles, don't bluff, I'll tell you something hard.

Yesterday, we went to your brother's car repair shop, and found a small utility room between the shop and the main house, which stored a lot of things, and found a shallow blood stain on the door. ”

As he spoke, Xu Dayuan put a photo of the compartment door on the small table, and then placed the backpack, wrench, wallet, gloves, etc., in order, and the detailed photos of the items.

Xu Dayuan smiled, pointed to the photo of the wrench with the pen in his hand and said:

"I won't talk about the wallet, I guess you also want to leave some memorial, killing someone and no one sharing these processes, it's so painful, isn't it? I can only leave these humble things behind, always reminding you of everything you have done.

After examination, it was found that there were traces of blood of nine people on this wrench, and after our DNA comparison, it belonged to nine of the nineteen victims.

However, on the façade of the wrench, it is this rubber part, we collected a left thumb fingerprint with blood stains, and after fingerprint comparison, it was found that it did not belong to you, but was left by your brother Wang Guangli.

As for the bloodstains, after comparison, it was found that it belonged to the DNA of Zhu Yuzhen, the deceased of the fifth white ossification, I think you may not remember this name, right?

The same method of killing, the same process of throwing the corpse, the same damage to the face of the deceased, and even around the wellhead of Sanquan Bay, we did not find a single drop of blood, which shows that you are there, right?

Did you instruct your brother to kill? Why? ”

Such continuous questioning made Wang Guangren stunned, and he didn't look away in time.

He is not afraid of death.

When I killed the first person, I expected this day, but it was just a question of whether it was a day later or a day earlier.

He wasn't afraid to be questioned.

If no one asks about it, these 'feats' will always be a secret, which is what he does not want to see.

When things are done, they need to be seen.

He thought that the police would interrogate him why he killed people?

Or even why kill the woman who sits on the stage?

Or interested in the killing process?

But the policeman in front of him could find out that there was a person who was not killed by himself.

The stunned gaze has already explained everything.

Xu Dayuan leaned across the small table, supporting the small table with both hands, so close, Wang Guangren could smell the tobacco smell on Xu Dayuan's body, he shrank back slightly, he didn't like this smell.

But Xu Dayuan didn't let him back down, as soon as he stretched out his hand, grabbed Wang Guangren's collar, and dragged the person directly in front of his eyes, and the two faces were no more than a punch apart.

"Answering my question, are you there?"

Wang Guangren shook his head, his eyes were fierce, the green tendons on his neck bulged, and he almost shouted with a roar.

"I killed people, only me! No one knows about my murder, and the wrench may have been used by my brother, after all, there are my brother's fingerprints everywhere in the car repair department, this is not counted, I want to drag my brother into the water, I don't know if you are really stupid, or if you think you are all detectives ridiculous. ”

Zhou Ning stared at Wang Guangren's hideous face, this person was honest and honest when he just came in, as if he had changed someone, and his eyes were like a demon from hell, wanting to destroy all the good.

His leg has been dislocated since childhood, and if he can go to a regular hospital, he will not become disabled if he can be corrected by surgery as soon as possible.

And his parents were absent early, and his brother raised him, do you want to hate a person who is a few years older than him and raised himself?

No way.

Then there must be someone who let him transfer this hatred and let him find a reason to hurt others, which is a very reasonable reason in his opinion.

Zhou Ning rubbed his chin, his stubble was slightly blocked, and he paused.

The two of them don't have beards, and they are almost the same as Cui Guanglin before, is it also a genetic problem?

"Has anyone gone to investigate the ex-wives of Wang Guangren and Wang Guangli?"

As she was talking, Liu Yufei walked in, holding a few pieces of printing paper in her hand, she naturally heard Zhou Ning's question, and couldn't help but smile and said:

"Just now Xu Da urged this, the investigation came out, Wang Guangli divorced very early, Wang Guangli was twenty-four years old in 1997, married in May of that year, divorced in October, as for Wang Guangren got married in October 2009, divorced at the end of 2009, a total of less than 30 days.

As for Wang Guangli's ex-wife, we checked the household registration information, this person went to Guangzhou, and there is no news for a long time, as for Wang Guangren's ex-wife Ge Hong......"

Speaking of this, Liu Yufei paused.

Zhou Ning leaned over and glanced at it, and was slightly stunned, because there were several messages below that were detained by public security, all of which were about this ex-wife Ge Hong, and the words selling Yin Piaochang were extremely conspicuous.

In an instant, Zhou Ning understood why this Wang Guangren had such a big grudge against the woman sitting on the stage, and his ex-wife actually went to be a chicken.

Coupled with the gossip in the village, Wang Guangren was even more eager to kill her, so he hated people in this profession very deeply, after all, women who lost their feet were willing to make up a tragic past for themselves, and men would pity her even more.

"Sister Liu, send Ge Hong's information to Xu Da, Wang Guangren will like this result."
