"It's obvious." Chu Nan said without hesitation.

"You can tell?" Zhang Zheng stared at Chu Nan in disbelief, "Comrade, you have to think carefully. This is about human life, so don't dare to talk nonsense."

The young policeman on the side said angrily: "What on earth do you want to do? We have investigated the scene ourselves and it is just an ordinary traffic accident.

You can tell it's murder from so far away? Do you think we are freeloaders?

Let me tell you, this is the captain of our Southern District Criminal Investigation Brigade, are you going to teach him how to handle cases?"

Chu Nan looked at the young policeman helplessly, not that there was anything wrong with him.

Are you young? Everyone who has been young will have a stage of blind worship of authority. It is understandable.

What's more, now that I'm just a passerby, it's good that I didn't get beaten when I came up to him and complained so much.

"Captain Zhang, can I say a few words?" Chu Nan asked.

"Tell me about it." Zhang Zheng said patiently.

Chu Nan came to a trash can not far away, pointed to a deep tire mark on the ground and said, "Look here."

Several people around Zhang Zheng came to Chu Nan and squatted on the ground to observe carefully.

After looking at it for a long time, Zhang Zheng said with a confused look on his face: "Little brother, there is just a tire mark, what does this mean?"

Chu Nan took out a napkin from his pocket and wiped it vigorously on the tire tracks.

Dark marks immediately left on the napkin.

Chu Nan put it to his nose and smelled it, then handed it to Captain Zhang.

"The mark is new, and there is a burning smell." Zhang Zheng frowned tightly.

"Yes." Chu Nan nodded, then pointed to the curb not far away.

"Look here, this cigarette butt is still burning, which means it was thrown away not long ago. These three cigarette butts are all from the same brand, so it can't be a coincidence that they were thrown together, right?"

While Chu Nan was talking, he picked up the cigarette butt with sparks and said, "Obviously it was just thrown away, but this cigarette butt is dry and has no trace of wetness with saliva. Isn't it strange?"

The young policeman on the side couldn't help but said: "Comrade, what are you doing? Didn't you say this was murder? If you know anything, tell it immediately! Otherwise, don't waste time."

I can tell you that it is illegal to make false alarms."

Zhang Zheng waved his hand to stop the young policeman, stared at Chu Nan and asked: "Young man, what do you want to say?"

Chu Nan smiled lightly and said: "Captain Zhang, you are an old policeman. You should know what circumstances will affect saliva secretion, right?"

"Nervous?" Zhang Zheng said subconsciously.

"Yes, nervous." Chu Nan nodded, "I just observed that the tire tracks match the tires of the car that caused the accident.

This shows that the car involved in the accident did not accidentally hit the deceased while passing by.

Instead, he suddenly started the car just as the deceased was passing by. The tire wear marks on the ground showed that there was a violent acceleration process.

These cigarette butts are all near the tire tracks and can be determined to have been smoked just a few minutes ago. Therefore, it can be determined that these cigarette butts were probably left by the driver who caused the accident.

Of course, it is very simple to determine whether these cigarette butts were left by the driver who caused the accident. Just make an identification.

If these cigarette butts were left by the driver who caused the accident, then I can assume that the driver has been waiting here, and he has been waiting for a long time.

Let's think about this scenario. The driver who caused the accident was waiting in the alley early in the morning. During the waiting period, he was very nervous.

When the deceased passed by, he accelerated violently, causing the victim to die on the spot.

This series of doubts can't all be coincidences, right? If they are all coincidences, then it can only be said that the deceased was too unlucky."

Chu Nan's words made everyone present widen their eyes.

Zhang Zheng's scalp felt numb for a while. The young man's analysis in front of him made sense.

All the signs add up, and this is basically a premeditated murder.

This is how case handling is, individual clues have no actual value at all. Evidence is to combine all the scattered clues into an evidence chain.

This is also the place that best tests the ability of a criminal investigation police officer.

Obviously, I lacked the ability and failed to connect these subtle clues.

It was so dangerous that I almost turned a murder case into a traffic accident.

"Little brother, shall we go together?" Zhang Zheng couldn't help but ask.

"Reporting to the leader, I am Chu Nan, a student of the 18th class of criminal investigation major at Jiangnan Provincial Police University. I am preparing to report to the Badaoguai Police Station." Chu Nan saluted in high spirits.

Zhang Zheng looked at Chu Nan in surprise and said with admiration: "I haven't even joined the job yet, but I have the ability to observe carefully and have solid basic skills. This is something I learned in school.

He's a good candidate. You major in criminal investigation. Isn't it a bit unfair to go to the police station? Are you interested in joining our criminal investigation brigade? "

"Haha." Chu Nan smiled awkwardly, "Thank you, Captain Zhang, for your appreciation, but..."

Chu Nan smiled but hesitated to speak.

It's not that he doesn't want to go to the criminal investigation office. Having been a policeman for half his life, he naturally knows the rules.

The police system is also a place where people are concerned. If you change mountains without saying a word, how will you let others think of you?

From now on, you will always lower your head and not look up to meet your colleagues, so you still have to pay attention to this kind of thing.

Zhang Zheng also smiled awkwardly, pretending to be calm and said: "We will talk about this later."

After all, it is a system, so it is really not good to rob people like this.

The grassroots police stations themselves are very aggrieved, and being treated like this is a bit like bullying.

Moreover, Zhang Zhengke, the director of Badaoguai Police Station, knows that the city's police force is notoriously difficult to deal with.

If he caught his little tail, it would be enough to give Zhang Zheng a headache.

Zhang Zheng's attention returned to the scene, and he said with some worry: "Xiao Chu, your discovery was very timely.

However, these evidences only suggest that there is a possibility of homicide and cannot be confirmed.

This kind of case is difficult to determine without conclusive evidence.

The most troublesome thing is that this is a main road, and there is no way to preserve the scene and missing evidence."

Chu Nan said: "Let's check the surveillance first. As long as it matches our speculation, even if there is no concrete evidence, the suspicion of the driver who caused the accident will be confirmed.

As long as we take the person back and we investigate slowly, we can always find some clues."

Looking at the burning eyes of Zhang Zheng and Chu Nan, Team Liu grinned in embarrassment.

"Xingfu Road is a small road, and there are only two cameras on the entire road.

One is at the entrance of the Third Ring Road, and the other is at the entrance of Xingfu Community over there. It happened to be monitored and inspected in the past two days, and both cameras are under maintenance."

"Can't you just say there are no cameras here?" Zhang Zheng rolled his eyes at Team Liu angrily.

Captain Liu smiled awkwardly and said nothing.

Chutian groaned helplessly. It seemed that behind every case, there were a few cameras that broke down at the first moment.
