"I remember that when Dr. Liu left my house that night, it was around 12 o'clock in the evening, it was very cold at that time, and Dr. Liu wrapped himself tightly, said goodbye to me and left. ”

"I don't dare to say if there was any movement in the car accident, but not long after I returned to the house, I did hear a car driving on the side of the road, and there was a lot of movement. ”

Gu Chen frowned and continued to ask him, "Then do you remember what the movement was at that time?"

"Well...... Let me think. The old man didn't seem to have a very good memory, so he looked up at the clouds in the sky, and then tried to recall: "It seems that he knocked down something on the side of the road, yes, some sundries." ”

"Bumping into debris?" Gu Chen hurriedly walked to the edge of the yard, close to the side of the road, turned around and asked the old man, "Uncle, which thing was hit?"

"That's right?" said the old man, pointing to an abandoned signboard stacked on the side of the road with his cane, "These things are all discarded signboards from some town shops, which were purchased by the villagers and put here to make new ones." ”

Gu Chen didn't think much about it, he directly kicked his left leg, put his right hand on the fence, and jumped over the fence more than one meter high, and then hurriedly walked to a few broken signboards on the side of the road.

But Gu Chen quickly frowned again, compared the situation on the side of the road, and then walked back to the fence and said.

"No, it can be seen from the roadside traces that this pile of old signboards is not placed in the middle of the road, and there is no turning road here, how can it be hit?"

The old man shook his head: "I don't know about this, I remember seeing through the window that the lights of this car were swaying, but the speed was fast." ”

"After knocking through these old signs, I drove away. ”

After thinking about it, the old man said again: "Oh yes, it looks like it has been more than ten minutes, I heard a movement in the distance, a little loud." ”

Gu Chen snapped his fingers: "I know." ”

"You...... Do you know?" the old man didn't know how to do it, and asked Gu Chen weakly: "Little comrade, what do you know?"

"I know why cars hit old billboards on the side of the road. Gu Chen said.

Lu Weiwei also hurriedly said: "Senior Brother Gu, you wait for a while, let me guess." ”

Gu Chen nodded and didn't speak.

So Lu Weiwei spread out her hands, and then said slowly: "You mean, that car, when the road is very spacious and there are no curves, hit the old signboard on the side of the road." ”

"And judging from the statement in the uncle's mouth, the light of this car is swaying and the speed is very fast, could it be that the driver is drunk driving?"

Gu Chen smiled and said directly: "That's right, the driver is very likely to have drunk driving." ”

Officer He frowned: "So, the murderer was a drunk driver, and after killing Dr. Liu, he was afraid that he would be directly responsible, so he threw Dr. Liu's body into the wasteland and then escaped?"

"Yes, that's probably the case. Gu Chen said.

Officer He suddenly walked back and forth in the courtyard with his hands behind his back, and then asked: "In that case, we must find the first crime scene, and only by finding the first scene can we find some clues." ”

"Otherwise, just by finding Dr. Liu in the wasteland, it will definitely bring a lot of trouble to the case. ”

Gu Chen smiled and said, "Senior Brother He, don't be too anxious, I can probably know where the crime occurred is." ”

"You...... Do you know?" Officer He was also stunned for a moment, and said unconsciously: "Then where do you say?"

"It's simple. Gu Chen also walked up to Officer He through the fence, and said lightly: "Didn't Uncle say it? This car was moving very fast, and it didn't stop immediately after hitting the abandoned billboard on the side of the road." ”

"But the uncle heard a motive coming from outside after ten minutes, and then there was no sound of the vehicle's engine, what does this mean?"

"It means that there was a car accident, and it means that the drunk driver hit Dr. Liu?" Lu Weiwei hurriedly walked to Gu Chen's side and finished answering.

Gu Chen snapped his fingers and said, "That's right, it was a crash, because the appearance of this car was not long after Dr. Liu treated his aunt and rode away." ”

"According to the driving speed of the battery bike and the bicycle, and the interval in between, this time period is very close to the time of the crash. ”

"That'...... Then can we find the first scene?" Lu Weiwei heard this, and probably understood what Gu Chen meant.

Gu Chen smiled and said, "That's for sure, because as long as we drive, according to the speed of that car that night, we can judge the location of the accident at that time." ”

"Although there will be some errors, the range is not large, and the first scene should be found. ”

"That's fantastic. When Lu Weiwei heard this, her whole person became excited, she hurriedly walked to the old man's side and asked the old man:

"Can you remember how long it took for that car to pass by your house and knock down an old billboard on the side of the road before there was a loud noise?

"This ......" Lu Weiwei said, but the old man was stumped.

The old man is very old and his memory is not very good, so he asked him to tell the specific time, and it was two days ago.

This is a bit of a test of the old man's memory......

Seeing that the old man was stunned there, Gu Chen smiled and continued: "Uncle, you relax first, close your eyes and think about it again, just give me an approximate time." ”

"Uh...... Then I'll try?" The old man also knew that the time he gave was very critical and he couldn't tolerate too much error, so he began to close his eyes and meditate again.

The scene suddenly fell silent, and everyone looked at each other, put their fingers to their mouths, and made a silent sign language.

At this time, the birds in the trees began to chirp.

The old man's eyes suddenly opened, and he said with relief: "I remember, I remember." ”

You speak slowly. Gu Chen didn't rush him.

The old man said lightly: "I remember that when I saw off Dr. Liu, it should have been around 11:50 in the evening, and after I saw him off, I specially looked at the clock on the wall, and it was indeed 10 minutes before 12 o'clock in the evening." ”

"And the car that passed by the side of the road after that must have not been past twelve o'clock, and it must have been about two minutes after I heard the impact before I heard the hour on the wall. ”

"There is still a time at 12 o'clock in the evening?" Lu Weiwei felt inexplicable.

Officer Wang suddenly glared at her, and Lu Weiwei immediately shrunk her neck again and stopped interrupting.

The old man smiled: "I'm not afraid of your jokes, my clock is that kind of antique, wind-up, every hour, it will ring once, so at 12 o'clock in the evening, I can also hear it." ”

"Then how long did it take for you to hear the car stop after you heard the hour signal at 12 o'clock in the evening?" asked Gu Chen.

"It's about 10 minutes, right?" said the old man, "After all, I just finished soaking my feet at that time, and the calculation time was exactly 10 minutes, which is a habit for many years, and there should be no mistake." ”

Gu Chen nodded and said with considerable satisfaction: "That is to say, this car, when it hit the waste billboard on the side of the road and left, it was about 11:58 p.m. ”

"And two minutes later it was the hour, and then another 10 minutes passed, and then there was a loud noise, and then there was no movement, and the time should have been 12 minutes. ”

Gu Chen looked up at everyone and said with a smile: "Then let's drive to find it, as long as we maintain a certain speed, the location in 12 minutes should be the first scene." ”

"That'...... So what are you waiting for? When Officer He heard this, he couldn't wait.

Officer Wang was indifferent, after all, there were many cases handled, and seeing Officer He's excited look, it really felt unnecessary.

After bidding farewell to the old man, Gu Chen estimated the previous speed and the extent to which the waste billboard was hit, and he could probably deduce that the speed of the vehicle that night was about 50 kilometers per hour.

After adjusting the speed of the car, Gu Chen drove everyone to look for it.

In the car, Officer Wang stared at him and said: "I said Lu Weiwei, you are responsible for looking at the right, Lao He and I are responsible for looking at the left, Gu Chen is driving and looking ahead, about 12 minutes, it is the time for everyone to search seriously." ”

"Got it, Wang. Lu Weiwei had already dropped the passenger window and leaned on the window to take a closer look.

Officer He also said: "Don't worry, Lao Wang, I should be able to find clues too, after all, there is no fork in the road here, there is only one road leading to the town, it is nothing more than looking for it on this road." ”

Several people were also communicating in the car, but Gu Chen never spoke, his eyes narrowed forward.

When the car reached the point about the 13th minute of the timer, the brakes suddenly slammed suddenly.

The occupants of the car all fell forward.

Lu Weiwei was also pulled by the seat belt, and the whole person was taken back again.

Officer Wang was knocked into Gu Chen's seat and bounced back.

Officer He was a little tragic, sitting in the middle of the back row.

Because he was not wearing a seat belt, Gu Chen's sudden brake directly made him pounce on the gear position in the front row.

"I'm sorry, Senior Brother He. Gu Chen smiled awkwardly and looked down at Officer He.

Officer He also raised his head and smiled: "No...... It's okay, it's your driving skills, be steady, don't brake suddenly. ”

"Poof!" Lu Weiwei couldn't hold back, and laughed directly.

Officer Wang was also angry and said, "I said Gu Chen, you braked so hard, did you find something?"

"That's right, there's a discovery. ”

Gu Chen didn't explain too much, he directly pulled the handbrake, unfastened the seat belt, and quickly opened the door and got out of the car.

Lu Weiwei didn't know how to do it, and she followed closely.

After Officer Wang and Officer He got out of the car, Gu Chen and Lu Weiwei were already squatting on the ground to check carefully.

"Marks, traces of sudden braking, and some blood stains on the ground. Gu Chen stood up, faced Officer Wang and said to Officer He: "In addition, I also found some small fragments, which should be fragments from the battery car." ”

Officer Wang hurriedly followed Gu Chen's guidance and squatted down to take a closer look.

After a while, Officer Wang confirmed Gu Chen's statement and said, "That's right, what you said is right, this should indeed be the scene of the car accident at that time, and it is also the first scene of the crime." ”

Gu Chen didn't hesitate, directly put on white gloves, and used long tweezers to clip the plastic pieces on the ground into a transparent forensic bag.

The blood stains on the ground had already dried on the road after two days.

Gu Chen quickly returned to the car and took a bottle of mineral water and a pack of wet wipes.

After opening the cap, Gu Chen poured water on the blood stains again, and then took out the wet wipes that everyone often uses to wash their faces on the night shift, put them on the ground, and gently rubbed and stirred.

The blood becomes less dry after being mixed with water.

Later, it was extracted by Gu Chen with wet wipes, and the wipes stuck the components of the blood on it, and Gu Chen put it in the bag of the certificate.

Officer He was dumbfounded......

This kind of operation, if it is placed in normal times, it is really rare.

However, Gu Chen's operation was smooth and very skillful, which made Officer He realize the gap between his ordinary police station and the police officers of the Criminal Investigation Team of the Furong Branch.

It was also watching Gu Chen complete the bloodstain extraction

Later, Officer He asked him, "Is it okay?"

"I'm going to look for it again. Gu Chen said.

Officer He looked left and right and asked, "What do you mean?"

"I mean, look around to see if there's anything else, like an item that the killer left at the scene, which can give us clues to solve the case. ”

"Oooh. "Officer He usually deals with some small police situations, although he is also an old comrade, but in front of Gu Chen, he is still unusually well-behaved.

Officer Wang also said: "Then hurry up and take a look, see what is around here, maybe the battery car will be abandoned nearby." ”

"Then let's split up. Lu Weiwei said.

Soon, everyone went to both sides of the road and began to carefully search the site environment.

Gu Chen and Lu Weiwei were on the left, and Officer Wang and Officer He were on the right.

It didn't take long for Officer He to hear Officer He yelling, and everyone immediately moved closer to him.

"What's the matter, Senior Brother He?" asked Gu Chen, who arrived first.

Officer He pointed to the edge of a pond and said, "Look, is this Dr. Liu's battery car?"

"It should be, right?" Lu Weiwei hurriedly stepped forward and filmed the scene with her mobile phone.

Officer Wang immediately said: "That's right, this should be the first scene, Dr. Liu, it is very likely that he was hit and killed here." ”

"Let's look and see if there's anything new. Lu Weiwei said.

Everyone continued to bury their heads in the search, and by the way, pulled the damaged battery car to the side of the road.

Gu Chen, on the other hand, stood on the side, using his specialization-level observation power to quickly search the on-site environment.

Clues that others take a long time to discover, after Gu Chen uses specialization-level observation, the effect is several times that of ordinary people.

It's not fast, it's accurate.

After a quick scan and search, Gu Chen didn't find any other clues.

So Gu Chen walked directly back to the side of the road and walked towards the police car.

"Senior Brother Gu. Lu Weiwei looked up at him and asked, "What are you going to do?"

"I would like to go back to the place where the body was found and see what new things have been found. Gu Chen said.

"Then I'll go too. Lu Weiwei wiped the dirt on her hands, and after brushing the mud from the pond on the lawn, she also hurriedly followed Gu Chen's footsteps.

Officer Wang said angrily: "Then you won't be looking for it here?"

"I'm not looking for it. Gu Chen opened the car door and said to Officer Wang: "Why don't Senior Brother Wang and Senior Brother He look for it again, after looking for it on one side of the pond, go to the other side to look for it." ”

"Senior Sister Lu and I will go to the scene where the body was found first and then take a look, maybe there will be some clues over there, after all, if the body is to be moved to the wasteland, the murderer will definitely leave some flaws. ”

"That's fine? Knowing that Gu Chen had a lot of ideas, Officer Wang no longer insisted on it, but added: "Regardless of whether you find clues later, remember to drive over to pick us up." ”

"Got it. Gu Chen smiled, got into the car directly, and took Lu Weiwei with him to return to the place where the body was found just now.

At this moment, the melon-eating crowd gradually dispersed, and the cordon where the body was found had already been removed.

"Senior Brother Gu. Lu Weiwei walked to the place where she had just arrived, and said with some hesitation: "You said that the murderer wanted to take such a big time to move the body here, what did he want to do?

Gu Chen didn't look at Lu Weiwei, he had been searching carefully, and he also said casually: "The murderer probably doesn't want to leave too many clues at the first scene, or rather, what did the murderer do to Liu Yisheng's body." ”

"What?" Hearing Gu Chen say this, Lu Weiwei tilted her head: "You mean, the murderer ...... Doctor Liu's body?"

After thinking about it, Lu Weiwei hurriedly gave herself an ear scraper: "Uh! It's evil, it's evil, I actually want to be crooked, Senior Brother Gu meant, it must be that the murderer has done something to the corpse, right?"

"That's right. Gu Chen nodded, a little curious: "I'm a little interested in this murderer now, he seems to have some means, at least, he can use his own means to successfully deceive Gao Chuanfeng and me." ”

"This is enough to show that this guy is by no means an ordinary person, but a guy with a certain level of knowledge. ”

"Is it really so powerful? Even Senior Brother Gu was deceived by him?" Lu Weiwei thought at the time, Gu Chen should not misjudge the time of death of the corpse.

However, the clues obtained from the family of the deceased and the eyewitnesses of the patient completely contradicted the judgments of Gu Chen and Gao Chuanfeng.

At first, I thought that Gu Chen was also the time when the horse stumbled, but now it seems that the murderer is too cunning.

Lu Weiwei secretly glanced at Gu Chen, who was searching at the scene, and couldn't help but feel that Gu Chen seemed to know something.

However, he now needs some definitive evidence to prove his speculation.

"Huh, what is this?" While Lu Weiwei was sluggish, Gu Chen made a discovery.

Lu Weiwei woke up like a dream, immediately recovered from the meditative state just now, and hurriedly trotted over.

"Senior Brother Gu, have you made any discoveries?" Lu Weiwei asked.

Gu Chen used a pair of long tweezers to take out a black wallet from the messy grass.

"This ......" Lu Weiwei was stunned for a moment, and hurriedly asked Gu Chen: "See what's inside?"

Gu Chen was not idle, and directly took out some change and business cards from his wallet.

"The murderer doesn't love money?" Lu Weiwei was stunned for a moment: "If he loves money, there is no need for him not to search his body?"

But just as Lu Weiwei was suspicious, she found that from the wallet in Gu Chen's hand, a cuboid suddenly fell.

......
