Chapter 138: Case Closed

The driver of the private car who provided the clue was a local who drove to Longde Village to eat the chicken with pork intestines and tripe.

In fact, most of the cars in the parking lot that day were here to eat the chicken with pork intestines and tripe.

Although there were other food stalls and snack stands nearby, they were all neighborhood businesses, and no one drove here to eat.

Only this chicken with pork intestines and tripe, for some reason, was famous. People who came to Longli County seemed to feel that they had come in vain if they didn't come to this store to eat once.

Anyway, the quantity was large, the taste was really good, the price was very affordable, it had always been very popular, and it was easy to park nearby.

As for the residents who originally parked here, there were actually very few of them, and most of them were commuting to work.

Hou Lejia quickly sent a team to the parking lot. While investigating the scene, they also took the parking lot's entry and exit records and compared them with the license plates in the entry and exit video.

Jiang Yuan followed the Longli County Police Dog Squadron to find the source of the bloody smell.

The police dog squadron of Longli County now has three dogs, one of which is in training and is still a trainee dog.

One is in his prime and is a diligent and lazy dog.

The other is the meritorious dog Heizi, who has won the second-class merit and has two bowls for eating, just like Jiang Yuan who won the second-class merit.

In terms of the use of police dogs alone, Longli County is still somewhat well-known in the province.

They really use them very well. Now, although Heizi is a little older and has fewer working hours, there are new strong police dogs "white-collar" to take over, and the third generation of police dogs is also in training. It can be said that the continuation of the dog skills of the three generations of old, middle-aged and young is a rare excellence in the province.

The one dispatched today is the meritorious dog Heizi.

Heizi's back is in a straight line, and the Doberman's unique pointed ears are straight up. He only lowered his head slightly all the way, and ran briskly with people towards the place with bloody smell.

Heizi, who costs 75 yuan a day, doesn't look old at all. He looks like a man, woman, and LGBTQIAPKDXREW who are still fighting on the front line of nightclubs at the age of 40. Only his eyes flash with a look of being strong and unwilling to accept defeat.

Woof!

Heizi shouted, and seven or eight people followed him.

Jiang Yuan also trotted over. He had to be on guard against some cute kid who excitedly destroyed the scene.

Needless to say, it won't happen. It's impossible. You will know from visiting many crime scenes that there are stupid thieves and not smart enough policemen.

When we arrived at the place, we saw an open channel and there was no obvious blood.

"I guess the suspect changed his bloody clothes while standing here." Zheng Xiangqian, the captain of the serious crime squad, also came over. He looked up to find the location of the surveillance camera and made a judgment. He squatted down and sniffed hard close to the ground, and stood up and said, "He also peed."

Heizi barked "Woof woof" twice, probably not very happy that someone took his job away.

Jiang Yuan suddenly realized what he had heard. Indeed, if he didn't change his bloody clothes, he would have trouble driving into the county town and being seen by others. Changing in the parking lot was a very suitable place.

At this time, a young criminal policeman speculated: "He still carries clothes with him. Is it possible that he premeditated murder?"

Jiang Yuan glanced at him.

This man is not smart enough, and his active speaking state shows that he does not think he is not smart.

"Premeditated murder, with clothes but no weapons?" Zheng Xiangqian lowered his head and replied, and blocked this road.

This is a problem with the investigation route, and he would not let a stupid child interfere.

From the current evidence, the possibility of premeditated murder is too low. Moreover, the most basic point is that the current suspects have cars, so why do they premeditate to kill an old man who picks up rubbish?

If there is a grudge, then he must have a weapon that can kill people quickly. Even if it is just to vent anger and beat, it can be more fully prepared. Things like parking in the parking lot, if it is premeditated, it is too stupid.

No one paid much attention to the silly boy's words.

Jiang Yuan put on a mask and took samples from the open channel with Longli County's own on-site survey.

The open channel smelled a little, but to be honest, the bodies had been dug out, so what was the big deal about digging an open channel. The smell of urine the next day was a little lighter.

The only thing that was a little uncomfortable was that the working environment was too outdoor.

The people coming and going in the parking lot and the police dog Heizi next to him looked at Jiang Yuan with a slightly embarrassing look.

After Jiang Yuan took the sample, he also stared at Heizi for a while.

In other words, this dog was unfamiliar. If Dazhuang dared to stare at him like this, Jiang Yuan would have plucked it bald.

"That's it."

Jiang Yuan put the sample box in the car and said to Zheng Xiangqian.

Although they may not be used in the investigation stage, these things can still play a certain role in the litigation stage. If you encounter a lawyer who resists stubbornly, some of them can still play a big role.

Of course, it would be good to take it back for DNA testing and compare it with the DNA that Jiang Yuan had wiped before. It would be good to have an extra layer of insurance.

A group of people came excitedly and left in disappointment. Not to mention the expected bloody clothes and murder weapons, there was not even a little sweetness.

Fortunately, the police who went out from another line brought back good news.

Not only good news, but also the suspect, the car and a bunch of other messy physical evidence!

"So, the person was caught?"

Wu Jun woke up from a nap and went directly to the Criminal Police Brigade from the guesthouse.

Jiang Yuan said, "Yes," and said, "He is being interrogated. He is a young man in his twenties."

Wu Jun glanced at the young man Jiang Yuan and said, "So it was a murder in passion?"

"It seems to be repeated." Jiang Yuan shook his head and said, "I just saw the people from the serious crime squadron go out. They should be investigating and collecting evidence."

"What evidence is there? He has been dealt with by so much blood in the car. The murder weapon?"

"The murder weapon and the bloody clothes were burned together. It is said that it was a plastic water pipe used for decoration, a PPR hot water pipe. I heard it from them." Jiang Yuan replied, and then said, "It was not burned cleanly. The wreckage was taken back."

Wu Jun was a little happy and whispered, "This guy has something. The murder weapon has always been a difficult problem to solve. It's just that he is not professional. He should practice more in advance. How did he burn it? Where did he burn it?"

"In a camping site, it was set on fire in a large iron barrel." Jiang Yuan actually had the same curiosity.

In the past and present, there have always been smart people trying to eliminate evidence.

A more interesting choice is to use a dagger made of ice. After killing someone, it melts and the murder weapon cannot be found (not popular science... please do not learn).

Plastic sticks have the same effect, but they are not direct enough when killing people. There is too much black smoke when burning.

Two police officers from the serious crime squadron who went out hurriedly returned with a girl.

The girl was between 18 and 48 years old, with light makeup, long pants and white T-shirt, and looked very clean. The high ponytail was a little fluffy and naughty.

Jiang Yuan and his apprentice looked at each other and understood that the interrogation should be over.

The new person might be a witness or something.

Jiang Yuan was still guessing, and Wu Jun went straight into the interrogation center to watch the surveillance video.

Jiang Yuan was embarrassed to go there. There were many people in there, and he was not in a hurry.

Not long after, the girl came out and went out without hesitation.

After a long time, Wu Jun came out with a serious expression.

"This is..." Jiang Yuan couldn't help but become curious.

Wu Jun sighed, pursed his lips, and said, "Let's go out and smoke."

Jiang Yuan nimbly opened a pack of Zhonghua cigarettes, handed it to Wu Jun when he went out, and lit it for him.

Wu Jun took a deep breath, exhaled the cigarette, inhaled it again, exhaled it again, and then said: "The murderer is the young man who was caught today. The motive... is different from what we thought."

"Is it because of that girl?"

"Well, after the young man separated from his companions, he saw the girl and pestered her for her WeChat. The girl refused to give it to him, so he followed her all the way and was seen by Zhang Hong who was picking up rubbish."

Wu Jun took another puff of cigarette and exhaled again, saying:

"Zhang Hong stepped forward to stop the suspect, and the girl took advantage of the chaos to run away. The suspect became more and more angry, so he chased Zhang Hong to his home and beat him to death."

Jiang Yuan's eyelids twitched when he heard it: "Just for this? Can't you be angry?"

"I think there's more to it than that." Wu Jun glanced in the direction of the gate and said: "The harassed girl not only didn't call the police later, but the police asked her yesterday, and she didn't say anything..."

Jiang Yuan was silent for a few seconds.

The law does not require things like repaying a favor.

If a person is unwilling to repay a favor, the police can't do anything.

Jiang Yuan asked: "How did you find this girl? Did the suspect say so?"

"Yeah." Wu Jun sighed: "Otherwise, the cause of death is unclear. Neither of them can explain it clearly."

Jiang Yuan knew that the two people he was talking about were the suspect and Zhang Hong.

It was a bit fucked up. Jiang Yuan kicked the steps in front of him, and his toes hurt a little.

The cigarette was a bit choking, and he couldn't help coughing.

Wu Jun looked ahead with a bleak look.

After smoking, he stepped on the cigarette butt, patted Jiang Yuan's arm and said: "It's okay to solve the case. In this world, right and wrong cannot be argued. Just do what we can do well."

Jiang Yuan responded: "Yeah."

"Master, why don't we go for another meal of pig intestines and pig stomach**, that's good."
