On The Day Of My 100th Blind Date, I Arrested My Date Chapter 565

Moreover, Chen Yan personally inspected the mixer truck of 12 people.

Chen Yan confirmed that these cars were very "clean" without any smell of blood.

According to the current clue analysis, the murderer is likely to be the driver of the concrete mixer truck.

The other party should have brought the decomposed corpse in with a mixer truck after decomposing it.

The corpses are then dumped into the conveyor belt while the mortar is being loaded.

But there was not the slightest smell of blood in the 12 cars.

But if not these people, who else could it be?

Zhang Chaoyang accompanied Chen Yan and questioned these drivers one by one, but also found nothing.

"Team Chen, could the murderer be the driver who loaded the mortar in another mixing station, and then deliberately threw the body into the No. 9 mixing station?"

There is a possibility, but not too great.

"I asked these people, the driver who loaded the mortar at the first mixing station never stopped at all."

Chen Yan pointed to the gate: "There are a total of ten mixing stations in the yard, and each mixing station has a fixed driver for pulling mortar."

"They drove into the yard one by one in order, and then loaded concrete under their mixing station."

"That is to say, a mixing station basically has only one concrete mixer truck to load mortar at the same time."

"You can see the loading process of them. They watch the mortar load behind the rear of their car, and the control button installed in the mortar is next to the conveyor belt."

"Each driver got out of the car to control the opening and closing of the conical mixing bucket. If the murderer threw the corpse into No. 9 mixing station from another mixing station, it would be difficult for the driver who loaded the mortar not to notice."

Zhang Chaoyang nodded.

Chen Yan was right.

If someone from another mixing station came over, the driver who loaded the mortar at No. 9 mixing station could not be invisible.

Because the whole process is uninterrupted, one car goes out, one car comes in, and the time when there is no one in the middle is very short, only a minute or two.

In such a short time, the murderer could not succeed.

So, what part went wrong?

In the office next to the mixing station.

Chen Yan was checking the mortar transportation records on the night of the incident one by one.

"This car, Chen Yan pointed to one of the records. I see that ordinary vehicles can transport mortar three times, or even four times. Why is this car only transported once?"

The custodian in charge of recording the transport volume is called Wang Zhi: "The driver of this car is called Qin Yu."

"There was something wrong with the drive shaft of his car that day, and he went to repair the car after pulling the car, but he didn't come after that." Didn't come?

"When did the truckload of mortar he transported go out?"

"This... We didn't record the specific time, but it was probably around 12 o'clock in the evening. I don't remember exactly, but it must have been less than 1 o'clock."

"I eat instant noodles at 1 o'clock every night, and he left not long before I eat instant noodles."

12:00 or less than 1:00?

Zhang Suosuo and Tao Lin were killed between 8pm and 10pm the night before yesterday.

The other party left between 12 o'clock and less than 1 o'clock...

There were two or three hours in the middle, which was enough for him to dismember the body.

"Arrest Qin Yu immediately!"

after an hour.

Chen Yan met Qin Yu at the construction site of Wanghai Building.

"It really has nothing to do with me. I went to repair the car that day. It took me a whole night to fix it. If you don't believe me, you can go to the repair shop and ask. I was there all night!"

Unexpectedly, Qin Yu wasn't timid in the face of Chen Yan and the others, but a little nervous.

"Collect the shoe prints and compare them with the ones found on the spot!"

There is no need to go to the repair shop, the murderer left clear shoe prints in the water pump room, and by comparison, you can tell whether Qin Yu is the murderer.

But, unfortunately, the results of the comparison came out after ten minutes.

Qin Yu's shoes were size 44, and the shoe prints found at the scene were size 41.

Qin Yu is not the murderer!

Qin Yu's mixer truck was also checked by Chen Ya himself, and there was no smell of blood.

call…

The thread is interrupted again.

With so many cases, Chen Yan felt very tired for the first time.

When investigating Zhang Suosuo, Chen Pei's appearance made Chen Yan think that this was the murderer.

But Chen Pei is not, he has no time to commit crimes.

When investigating Tao Lin, Zhang Baoqiang's appearance also made Chen Yan think that this person was the murderer. However, there was no conclusive evidence at the time.

Although the other party's alibi was not particularly rigorous, but now it seems that the suspicion has been completely ruled out.

When several people were questioned, they all left fingerprints, footprints and even DNA information tests in the third team as usual.

After the murderer's footprints were found in the water pump room, Wu Zhiguo had compared all the suspects in the process of handling the case.

Feedback turned out to be...neither.

From the earrings and rings found on Zhang Suosuo's body and the necklace found in the grass on the side of Kunlun Road, it can already be concluded that the murderer did not kill for money.

After investigating all the relationships between Zhang Suosuo and Tao Lin, the suspects of the corresponding personnel were also ruled out. There is also no possibility of killing for love, for vendetta, or because of conflicts of interest.

Now, it seems that there is only one possibility left.

Accidental killing.

After making this judgment, Chen Yan decided to return to Yuanfang Commercial Concrete Company again.

Since the murderer dumped his body at the No. 9 mixing station of the Yuanfang Commercial Concrete Company, there will definitely be clues left behind. This time, in addition to the driver who transported mortar at the No. 9 mixing station, the drivers who transported mortar at other mixing stations were also included in Chen Yan's investigation.

"Everyone is divided into 10 groups, and every driver on the night of the incident must be questioned. The key point is to see if anyone found anything unusual that night!"

When all the clues were interrupted, Chen Yan could only adopt this stupid method.

Crowd tactics, all drivers who worked that night were included in the scope of the investigation.

"No abnormality. I am working at No. 1 mixing station. No. 9 mixing station is a few hundred meters away from me. I didn't pay attention."

"Our No. 2 mixing station is far away from there. If you want to ask about No. 1 mixing station and No. 3 mixing station, I can still watch it. I really don't know how far away it is."

"I was at Mixing Station No. 8, and that night was the same as usual, to say it was abnormal..."

Zhao Cunfeng is 34 years old today, and has been working here for seven years. Because he often stays up late, he looks older, like a middle-aged man in his 40s.

"A mixer truck seemed to have entered the wrong yard that night. Is this considered abnormal?"

Into the wrong yard?

Zhang Chaoyang's heart trembled: "Tell me what's going on."

"Actually, it's nothing. There are more than a dozen commercial concrete companies in our area, and our distant company is in the middle. Many new drivers will drive into the yard by mistake."

"It was about midnight that night. I forgot the exact time. At that time, I was just filling up the mortar and was about to leave. As a result, a new car that I had never seen before was parked next to it."

"I have been here for a long time, six or seven years, and I am familiar with the cars running in the company, but I haven't heard of anyone buying a new car recently."

"After that, I yelled casually. The driver was quite young, and he was taken aback when he saw me."

"I said where did you come from? I haven't seen it before. Did you go to the wrong place?"

"The young man looked at me, didn't say anything, and I didn't pay attention. There was still a car waiting for work behind me, so I left."

"Do you still remember that person's appearance and license plate number?"

Zhao Cunfeng scratched his head: "It's late at night, so I glanced at him. The guy has a short cut and is quite fair. The car is new. It seems he hasn't registered yet."

Gan!

Zhang Chaoyang immediately reported the news to Chen Yan.

new car?

Misplaced?

After midnight?

How can there be such a coincidence!

"Immediately inspect the vehicles of all commercial concrete companies in the surrounding area, especially new cars, or new cars that were registered yesterday or today!"

"Yes!"

With clues, action is no thing.

All inquiries about the driver were suspended, and a team immediately rushed to all surrounding commercial concrete companies. In the office, Chen Yan found the custodian Wang Zhi: "Are there many mixer trucks that have gone to the wrong place?"

"It's not too many. It doesn't happen every day, but it's not too rare. We have more places here, and the driver turnover is also high. It's not new for some novice drivers to go to the wrong place at night."

Chen Yan's eyes flickered as he left the office, this time the clue...

Hope is great!

The place where Yuanfang Commercial Concrete Company is located is the gathering place of concrete mixing companies in the northern suburbs. The specific number of commercial concrete companies gathered in this area is 12.

Although Chen Yan arranged for 10 investigation teams to disperse the investigation of the suspected vehicles, these companies are not small in scale, and the scale of Yuanfang Commercial Concrete Company is neither the largest nor the smallest.

Chen Yan had a general understanding. The largest commercial concrete company in the vicinity has more than 200 concrete mixer trucks, and the smallest has more than 50 vehicles.

On average, each has about 100 vehicles. Yuanfang Commercial Concrete Co., Ltd. is a medium-sized company among more than a dozen companies, and its location is in the middle of more than a dozen companies.

The vision is not clear at night, and it is indeed possible to go to the wrong place.

Liu Qingshan, Zhang Chaoyang and others asked relevant questions in other companies, and the answers they got were similar to those of Wang Zhi.

This kind of thing basically happens every day in the whole area, and everyone has long been familiar with it.

Therefore, when the new car appeared on the night of the incident, no one felt anything unusual.

Although there are many companies and vehicles to be investigated, the objectives of each group's investigation are relatively clear.

There are very few new cars.

Two hours later, the news came together.

"Team Chen, only 12 new cars were purchased in the entire area on the day of the incident. This is the specific breakdown."

"12 new cars...."

Chen Yan took the materials: "Have the drivers of these mixer trucks been found?"

"Seven people have been located and five people are on the way now and have not returned yet."

Liu Qingshan looked at the time on his phone: "The slowest one took more than an hour. We have collected the shoe prints of the 7 people we have found so far, and the comparison results are unsuccessful."

"Now we're waiting for the other five."

"it is good!"

Chen Yan put down the materials. Once the scene of the first crime was discovered, the murderer left clear shoe prints on the scene.

Among these people, only the shoe prints of the person and the shoe prints at the scene of the crime can be checked, so the other party must be the murderer.

Of course, even if there are no shoe prints, the other party must be a corpse transported by a mixer truck.

Just two days had passed since the incident, as long as Chen Yan found the other party's car, he might find some clues in the car.

Even if the other party has been cleaned, the blood test reaction does not mean that the blood will not be visible after cleaning.

The inspection of blood traces is actually a very advanced knowledge.

Blood trails left at any crime scene are unique.

Through the detection of blood traces, not only can it be judged whether the place where the traces were found is the scene of the first crime, but it can also bring a lot of information to the investigators.

In general blood trace detection, the first step is to determine the blood trace.

Whether it is human blood or animal blood, because blood contains hemoglobin, which is rich in iron ions.

The existence of iron ions is the fundamental basis for the determination of blood traces.

Determining bloodstains is the first step in blood traces detection.

Fresh traces can generally simplify this step. The difference between blood and paint or other red substances is still very good, and it can usually be distinguished with the naked eye.

However, traces of dried blood are generally brown in color.

This brown is not fixed, because the blood concentration and the depth of the color will change.

Some red material will also leave similar brown marks after drying.

Here it is necessary to judge the traces, whether it is blood or other substances, is the first step of judgment. After that, it is necessary to identify the blood type, analyze and judge whether it is human blood or animal blood.

The blood composition of each creature is different, and the blood of some animals is not even red.

By comparing the components, we can analyze whether it is animal blood or human blood.

Then it is to analyze the blood type and dna composition of the blood.

In addition to the above analysis, the investigation of blood traces has many other functions.

For example, judging the source, direction, and method of blood splashing from the shape of the blood splash can simulate and judge the murder weapon and modus operandi used by the murderer.

For example, several common bloodstain shapes.

Spray, wipe, breath spray or transfer.

Moreover, even for bloodstains of the same state, unique information can be extracted according to the size and degree of roundness of the blood droplet.

Some masters can even judge the cause of death of the deceased, the fatal part, and even whether the murderer used the left hand or the right hand to commit the crime through the analysis of the shape of blood stains.

An hour later, the other five drivers returned one after another.

And when the shoe prints were collected and compared, a young man named Zhang Tao was quickly identified among the last five people.

trial room.

Zhang Tao sat on the interrogation chair fidgeting, with fine beads of sweat dripping from his forehead, his eyelids were constantly beating, his hands were twisted together like cross scissors, and his lower limbs were shaking unconsciously. Chen Yan and Liu Qingshan personally interrogated.

"Zhang Tao, where were you at 8 o'clock the night before yesterday?"

Zhang Tao's face was as pale as paper, and he didn't respond to Liu Qingshan's words.

"Zhang Tao!"

ah?

Liu Qingshan yelled, seeming to wake Zhang Tao up: "Officer...Officer...I...I didn't kill...I didn't kill..."

There is no silver three hundred taels here.

"Did I say you killed someone?"

"Where were you at 8 o'clock the night before yesterday?"

"I...I'm driving mortar"

Zhang Tao stuttered and looked very flustered.

"Zhang Tao."

Chen Yan straightened his body and looked at Zhang Tao: "If we can find you, it means we have the evidence of your murder."

"In the water pump room next to Kunlun Road, we found your footprints at the scene where your body was dismembered."

"And your mixer truck. Although you have cleaned it, the blood stains cannot be washed away with water."

"Even if you don't confess now, you can confess without a mouth."

"I hope you can calmly think about the situation you are facing. Whether you actively cooperate with us to explain the entire criminal process, or plan to resist to the end, you choose."

Chen Yan's words were not heavy, but they fell into Zhang Tao's ears, and every word hit his heart.

"I…"

Zhang Tao looked at Chen Yan, then looked down at the handcuffs on his hands: "I... didn't kill them on purpose..."

"That evening…"

It turned out that Zhang Tao was indeed transporting and pulling mortar that night.

It's just that his car is new and has not yet been registered, so it is not allowed to go on the road according to the requirements.

On the original road, sometimes traffic detectives would check, so he took the slightly further Kunlun Road that day.

"I just came back from the urban area that night. UU Reading www.uukanshu.com saw those two people near the third traffic light intersection on Heping Road."

It turned out that that night, Tao Lin drank a taxi and went to the suburbs with Zhang Suosuo.

As for what to do, no one knows.

"I saw it all. That man and that woman were having **** on the side of the road. When I came over, the car lights dimmed to them, and then the man stopped my car."

"I just drove by and took a casual look, and he slapped me twice when he came up. I was not convinced, so I tore up with him..."

"But I didn't expect that man to have a knife on him. He wanted to stab me at the time, but he drank too much. During the tearing, I snatched the knife and accidentally stabbed him..."

"real!"

woo woo woo...

Zhang Tao has already started to howl and cry: "I didn't intend to kill him, I really didn't mean it, it was his knife... his knife... woo woo woo..."
