Wrong Interrogation Room, The First Cracked Case Shocked the World

within the cordon.

Many police officers at the scene looked at Ning Cheng in shock.

If the autopsy found that the murderer's skin was sampled in the nails of the deceased Sun Huirong, and the DNA could be tested, what faster method could be used to test the DNA!

However, Ning Cheng actually said that there is a faster way to arrest the murderer!

It's too incredible!

Of course Ning Cheng has, except for his own layout.

The quickest way is to use the system sin value to filter!

The murderer asked Sun Huirong to be on the Moon Bridge in the river, pushed her into the water and drowned.

The suspicion of murder was pushed to Wang Peng's head step by step.

Judging accordingly.

The murderer should know Wang Peng's people and know Wang Peng's exercise habits very well.

At least I know that Wang Peng likes to run on the river at eight o'clock in the evening, and I know that the surveillance in the western area of ​​the river has been in disrepair and damaged for a long time.

On the whole, the layout people should be people in this area and are very familiar with this place.

In this way, the identity of the builder's murderer is well screened!

There may even be a crowd of onlookers at the scene who murdered Sun Huirong.

this guess.

It was not random guessing by Ning Cheng.

Rather, it has a case-by-case basis!

Because the subconscious murderer has an expressive personality, he often enjoys the process of the police solving the case after killing, and often hangs around at the crime scene.

"Will the murderer be in the crowd?"

Ning Cheng's sharp eyes patrolled the crowd.

From time to time, the crowd sounded the voice of discussion, and looked boldly and curiously into the cordon.

It is a pity that Ning Cheng did not find the murderer using the systematic sin value analysis.

The real murderer of the layout did not watch the police solve the case!

"It seems that the murderer does not have a performative personality. Is it really not that easy to solve the case?"

Ning Cheng smiled lightly, without any loss.

"Ning Cheng, you said you have a faster method than testing DNA, what is it?"

Zhou Ziyan couldn't help but asked curiously.

"Wait, let me stroke it!"

Ning Cheng waved his hand and looked at the direction of the onlookers.

Instead of continuing to try to find the murderer in the crowd, he was thinking in another way.

Wang Peng said that Sun Huirong, the blind date object, had no interest in him, and the suspicion was terminated half a month ago.

This confession is credible after Wang Peng cleared his suspicions.

In this case, why did Sun Huirong tell her parents that she has always kept in touch with Wang Peng online?

Ning Cheng has also had a blind date and knows the psychology of both parties.

Sun Huirong said this, most likely because she rejected blind date.

But I couldn't resist my parents' request.

So I kept in touch with Wang Peng on excuses to deal with my parents.

But when Sun Huirong went out last night, she must have gone to see people.

Whoever you see, as long as you restore the content of Sun Huirong's mobile phone through the technical department, you can find out the murderer and then deduce the truth.

This method can find the murderer, but it also takes time.

"Who will Sun Huirong meet?"

"There is no doubt that this person is the murderer, and this murderer is familiar with Wang Peng's living habits."

"The murderer is still from this area. He has a certain understanding of Wang Peng and Sun Huirong, and there is a causal relationship..."

gradually.

A criminal-mind image of the setter formed in Ning Cheng's mind.

"Sun Yan, I want to ask you a question!"

Ning Cheng walked over to Sun Huirong's father and asked aloud.

"Officer, who killed my daughter, can you help me find the murderer?"

Grandfather put his hopes on Ning Cheng, and begged bitterly: "Just ask what you want to ask, and I will tell you everything I know."

Ning Cheng asked, "I want to know, where does your daughter Sun Huirong often go these days?"

"She often told us that she was going to find Wang Peng!"

Sun Yan said in a low mood: "I thought you were dating, so I didn't ask more details."

Love dating?

Ning Cheng froze in his heart and asked:

"You didn't ask for details. Have you heard Sun Huirong mention to you where the date is?"

Sun Yan, the father, shook his head.

"Not once?"

Ning Cheng didn't give up: "You don't need to ask about the details of your daughter's love, but as a parent, you should be worried about your daughter's safety, right? I really don't know the location?"

The word "daughter is safe" stings Sun Yan and makes his eyes red.

At this moment, Sun Huirong's mother trembled, grabbed Ning Cheng's hand, and said eagerly:

"Rongrong said that she wants to come to Starbucks Cafe in this neighborhood!"

"In private, I asked her once!"

Starbucks Cafe, just across the river, belongs to this area.

Ning Cheng thought of the criminal portrait of the murderer in his mind, his eyes narrowed suddenly, and he said to Zhou Ziyan:

"Starbucks Cafe, I should be able to find the clues I want here!"

"Are you sure you can solve the case faster than DNA?" Zhou Ziyan raised her eyebrows.

"Yes, because I often drink at a coffee shop and know it well!"

Ning Cheng said: "And there is no dead-end surveillance there. Sun Huirong probably drank coffee there last night, and can find clues!"

"Why are you familiar with which coffee shop?"

Zhou Ziyan frowned and said, "Usually at the police station, I've never seen you have the habit of drinking coffee!"

Ning Cheng was a little embarrassed: "Can you not answer?"

"What do you think?"

"Well, I often ask my blind date where to have coffee!"

In an instant, Zhou Ziyan and the female forensic intern looked at Ning Cheng with strange eyes.

"Okay, let's go to the cafe!"

Zhou Ziyan agreed and ordered the team members to bring the body back to the forensic department for further DNA extraction.

On the other side, it is to visit the cafe.

The cafe is not far, just across the river.

It didn't take long for Ning Cheng and Zhou Ziyan to arrive.

"Welcome, what would you like to drink?"

Entering the cafe, the boss who was entertaining guests at the front desk caught Ning Cheng's attention.

He had already started the system sin value analysis, and immediately noticed the striking sin value above the cafe owner's head! .
