I want to be a super cop

Chapter 282

Returned from Liu Wentao without success.

Seems to be expected.

It seemed unexpected.

During the questioning process, Zhong Tianzheng didn't try to induce him to confess and strive for a good performance, and he didn't give him a picture.

The next whole day.

Zhong Tianzheng was sitting in front of the computer, watching over and over again the back view of a middle-aged man leaving in a peaked cap captured by street surveillance without any comparison.

He has always firmly believed that these two cases are definitely not isolated.

"Wang Yiwei's car hasn't been touched since the accident happened, right? After further investigation, they found that they had a fight in the car, so there must be some clues left behind."

Zhong Tian was looking down at the inspection results of the extracts from the car and said.

"Why are you thinking about extracting the information on the possible leftovers on the car again? Hasn't the relevant department already extracted it? Also, don't you need to read this surveillance? You have been watching it for a day."

Ah Xiang looked at Zhong Tianzheng who seemed to be in a daze, and said worriedly: "Don't worry too much about this case, right?"

"When I was watching the surveillance video, I kept thinking about a question, and then I found out."

Zhong Tianzheng didn't take up the topic of Ah Xiang, but paused the screen, pointing to the back view captured in the surveillance.

Watch it from the video.

This person has a slightly hunched back.

He held a lit cigarette in his left hand.

This is the only movement of the man recorded in the surveillance footage.

Zhong Tianzheng's voice was not loud, and he seemed to be talking to himself: "Tell me, why does he hold the cigarette with his left hand when he smokes?"

"what?"

Ah Xiang was taken aback.

She didn't understand what Zhong Tianzheng meant by asking this question.

"What's wrong with holding a cigarette in your left hand? Isn't this a very normal thing?"

Ah Xiang thought for a few seconds, but she couldn't think of the meaning of Zhong Tianzheng's thinking about this question.

"No no no, this is not normal."

Zhong Tian was taking out a cigarette and lighting it for himself.

At this time, he was holding a cigarette in his left hand.

"I've seen the pictures and reports of the wound on Wang Yiwei's shoulder. From the pictures and the explanation given by the doctor, the inside of the knife wound is slightly to the left and has a tendency to tilt to the left." Zhong Tianzheng exhaled smoke , continued: "This shows that when the murderer was holding the knife, he was holding the knife in his right hand."

"Isn't he a lefty?"

Ah Xiang was slightly stunned. She could only hear this meaning from this sentence, and defended: "But what does this have to do with holding a cigarette in the left hand? Although I don't smoke, in my impression, which hand should I use to smoke? Clamp, there is no obvious difference, right? It has nothing to do with the dominant hand."

"That's what people miss, it's a little detail that people don't notice."

Zhong Tianzheng grinned, and explained in a steady tone: "It's like saying that I am sitting in front of the computer now, and I may use my right hand to control the mouse to control the progress bar when I watch the monitoring, so I will use it habitually. Cigarette in left hand."

"However, if it is in daily life, when we are relaxing or even walking, when we don't need to use our right hand to do things, we will habitually use our right hand to hold cigarettes. You have noticed that No?"

Zhong Tian is emphatically explaining the difference between the left and right hands in the action of smoking.

"what?"

Ah Xiang seemed to have some insight, she frowned and began to think.

"Recall carefully, your father or your grandfather, when they usually smoke, do they always use their right hand to hold cigarettes when they don't need to use their right hand?" Zhong Tianzheng continued to say: "Furthermore Liu Wentao, he smoked twice in a row, did he use his right hand to hold the cigarette? I must have used my right hand at the time."

"When you say it, it seems that this is really the case!"

Ah Xiang suddenly woke up, and Shui Lingling's big eyes widened: "That is to say, the action of smoking and pinching cigarettes has nothing to do with the dominant hand. Pinching cigarettes with the left and right hands is a very habitual action. When the right hand is doing other things, the left hand will hold the cigarette."

This is a small detail that is easily overlooked and not obvious, and there is no obvious distinction between the dominant hand and the cigarette.

"That's it."

Zhong Tianzheng nodded knowingly: "Although this is just an inconspicuous action in daily life, it is indeed a small habit that everyone will have."

"For example, in the past when mobile phones had just developed and hadn't reached the level of one per person, when everyone squatted in the toilet, they must have been bored looking at the front or looking around. More people must have seen their own toilet. Look at the formulas for the shampoo or body wash right across from you?"

In order to show his foothold, Zhong Tianzheng once again confirmed: "Besides, when we chat on WeChat at night, as soon as you tell me that you are going to the toilet, I can immediately think that your hands and elbows must absolutely be It is propped on the thigh, and the left and right hands are used to operate the mobile phone to chat, if it is reading a novel, it is very likely that the mobile phone is held with one hand, and the thumb is clicked to turn the page."

"Completely correct!"

Ah Xiang raised her voice a bit.

only.

When she looked at Zhong Tianzheng, her eyes were a little more weird and guarded?

Zhong Tianzheng felt it.

Immediately rolled his eyes in return.

"You said so much just now, and it fully verified the strangeness of the scene where the man was captured by surveillance cameras when he was leaving." Ah Xiang took the topic and began to analyze: "From the analysis of Wang Yiwei's wounds, it can be concluded that the murderer His dominant hand is also the right hand, so his habit of pinching cigarettes when he smokes will be in line with the common habit you mentioned just now.”

"Why doesn't he hold the cigarette with his left hand?"

Zhong Tianzheng added: "On rare occasions, even if you don't need your right hand, you may habitually use your left hand to hold cigarettes."

"Except for rare cases, there is only one explanation."

Ah Xiang said in a sentence: "Although we don't have the scene of their fighting, we can imagine that when he attacked Wang Yiwei in the car, Wang Yiwei must have resisted. In the middle of the resistance, the murderer's left hand was also injured. Already!"

"Ideally, that's why, when he walks away, he doesn't pinch the cigarette with his right hand when he's smoking it."

"Ah."

Zhong Tianzheng nodded meaningfully.

What Ah Xiang said is absolutely correct.

The murderer was in the car and must have injured his left hand.

"That's why you proposed to search Wang Yiwei's car again. If he was injured during the process, there would be blood stains or wounds on his arms."

"correct."

Zhong Tianzheng snapped his fingers and grinned: "But I think it is unlikely that he left blood on the car."

"You can guess this?!"

Ah Xiang raised her eyebrows and looked straight at him with her big eyes.
