"But it's not convenient to use that way." Wang Tingfei looked at the things recorded in her hand and spoke.

Everyone's eyes moved to Wang Tingfei's body, and suddenly so many people looked at her, Wang Tingfei became nervous, and immediately didn't know how to speak.

"Don't be nervous, tell us what you think." Yang Mu patted Wang Tingfei's shoulder and told her to relax.

Wang Tingfei took a few deep breaths before slowly speaking out her opinion: "Earlier, the master said that the blade of this murder weapon is very narrow and the back of the knife is very wide, and the murderer's method is an act of venting anger. The force used is very large, and judging from this strength, this kind of knife is either not used with any strength, or it is used to slip. ”

"Skidding?" Everyone is familiar with this word, but they are a little confused about using it here.

"When people are nervous or after holding something smooth for a long time, sweat will be produced on their hands, and if this murder weapon is really as we imagined, the setting of the knife and the lubrication caused by sweat or blood when the murderer kills people will indeed cause the situation she said."

Ling Feng glanced at Wang Tingfei with some admiration, just by listening to the records, he could propose such an observational thing, and he was indeed a high-achieving student.

"From my point of view of the wounds, most of the injuries caused are basically the same, there should be no slippage, and the strength is about the same."

"According to Yizhihua, could it be that the murderer was originally the kind of person who was very strong and strong?" Zheng Wenxing put forward a hypothesis.

"I don't rule out this statement, but this murder weapon was modified by the murderer, and according to the reaction of force, is it possible for the murderer to improve this situation?" Yang Mu propped his chin and thought about this idea.

When the idea was proposed, the entire space fell silent, but no one came up with the idea for a long time.

"Newcomer, do you have any ideas?" Yang Mu finally set his sights on Wang Tingfei. A newcomer may be able to give a surprising answer.

After dealing with so many cases over the years, their thoughts are often habitually complicated, but the truth of the cases is often very simple.

Wang Tingfei thought for a while but shook her head and said, "No matter how you transform it, this kind of percussion will cause the hand to be injured in the opposite direction due to the reaction of force. It can be found in the crowd with injured hands"

"The improvement of the murder weapon also has to go through many tests, and there are no similar cases recently, which means that this is the first time the murderer has killed someone, and the murder weapon modified before should be an animal."

In the current situation, we can only seize this improved murder weapon to investigate.

"If you're looking for animals, you'll probably choose cats and dogs, which are more commonly found."

Yang Mu looked at the time and said, "Okay, let's look for it for the time being, you continue, I'll take someone to arrest someone first." ”

Through these analyses, their scope has narrowed down a lot, but the murder weapon has always puzzled them.

After Yang Mu had the information he got from Ling Feng, he finally identified a suspect.

Suspect Ning Bing, according to the investigation, Ning Bing was the owner of a gym and met the deceased through fitness, and they didn't know each other for a long time, but the relationship was very close.

There was contact with the deceased on the night of the crime, and during the time of the crime, the other party did not have an alibi, but the other party did not admit that he had killed someone.

As for the surveillance, because it was too late, only a vague shadow was captured, and it was vaguely seen that it was an adult man, but the specific face was not photographed.

Ling Feng was not interested in the interrogation, he was more interested in the murder weapon used by the murderer, but it was just ......

Ling Feng looked at the murder weapons that had been constructed in front of him, but in the end, none of them could reach the state he expected, which made Ling Feng a little distressed.

When Wang Tingfei came in with the information, she saw Ling Feng's distressed expression, and the corpse of the deceased was still dissected in front of her.

Hearing the footsteps, Ling Feng frowned, and only after seeing that it was Wang Tingfei did his brows relax: "What's the matter?" ”

"Here's what I've written down and organized, so maybe it will be useful to you."

Wang Tingfei carefully put the document next to Ling Feng.

"By the way, the captain said that he brought back a suspect and asked if you want to go over and have a look."

I remembered that I had just met the captain when I was sending the information, and it was better to convey the captain's instructions.

"No, no." Ling Feng refused without even thinking about it.

"Why, all the questions that should be asked here are finished, and there may be new discoveries to see if there are others." After hearing Ling Feng's refusal, he subconsciously asked.

Ling Feng's movements stopped when he heard this, and turned his head to look at Wang Tingfei, under the light, Wang Tingfei couldn't see Ling Feng's emotions clearly, but she knew that he was looking at herself.

Wang Tingfei was a little embarrassed to be looked at by Ling Feng like this, could it be that she said something wrong? Wang Tingfei thought about it, that's right.

"That ......" When Wang Tingfei was about to exert the spirit of asking if she didn't understand, Ling Feng finally moved.

"Let's go." Ling Feng put down his tools, took off his gloves, and walked towards the outside very simply, as if he had forgotten that he had just said that he was still firmly saying not to go.

Wang Tingfei couldn't react when she saw Ling Feng's refreshing movements, and she watched Ling Feng's figure leave in a daze for a while.

Ling Feng walked for a while and found that Wang Tingfei didn't follow, and when he turned around, he saw Wang Tingfei staring at him blankly, frowning, and regretting accepting such a dumb apprentice.

"What's the wait, this is the place of work, you have to go home in a daze." Ling Feng reminded loudly, and he knew Ling Feng's mood in his tone.

"I'm sorry, I'm sorry."

Wang Tingfei, who came back to her senses, immediately apologized, and then followed Ling Feng's footsteps.

The interrogation room is located on the first floor, which is an enclosed room divided into two parts, one for interrogation and the other for surveillance.

There is a single-sided glass in the interrogation area, and the interrogation room can be seen from the listening side, but the interrogation room cannot see the situation on the listening side from his side.

There were four people in the interrogation room, one was the policeman who was the record, the other two were their captain Yang Mu, and the other was Sun Chirui, one of their four talents.

And the person sitting opposite them should be the suspect Ning Bing.

Ling Feng looked at this person through the glass, and the focus was on the other party's hand.

"This person's profile."

Hearing Ling Feng's question, Wang Tingfei immediately found out the information that Ling Feng wanted from the pile of information in her hand. After searching for a while, she finally found the information that Ling Feng wanted, fortunately she had been prepared, otherwise it would have been embarrassing.
