Chapter 1103 Arrest
Jiang Yuan, Liu Jinghui and others followed Jian Louyuan's team and first went to the house rented by the female victim Li Miaoyan.
Perhaps because Li Miaoyan has an underage sister, the two rented a commercial house with two bedrooms and one living room. The rent was 2,600 yuan, which had already deducted most of Li Miaoyan's salary.
Just looking at this house, Liu Jinghui frowned.
It is actually more difficult to make ends meet than ordinary debts. From a psychological point of view, if a person's daily expenses can be covered by his daily income, then he is at best a deadbeat, and life can always be made, and it is easier for people to live.
But if a person's daily income cannot cover his daily expenses, people with assets will feel that they are "eating up all the money", and those without assets will naturally have a harder time. It is more difficult to rely on borrowing money to maintain life, and long-term borrowing is more difficult than long-term debt.
From this reasoning, Li Miaoyan's financial situation is probably more complicated than her bank flow.

Apart from anything else, her rent expenses were not reflected in the bank flow, so it was basically paid in cash.
"Let's start from the door. Take a few footprints first." Jiang Yuan gave orders standing in the living room, not in a hurry to go inside.
Mu Zhiyang stood beside Jiang Yuan with his hand in the holster, and Wen Ming led two local criminal police to search the corners of the room.
At the same time, two technicians also turned on the exploration lights and searched for a few footprints on the ground and began to fix them.
Jiang Yuan went over to take a look and confirmed: "It is basically the same as the footprints seen at the Dongxi Lake cremation site. Okay, let's start the investigation."
Footprints are not as specific as fingerprints. In theory, the possibility of two people having the same fingerprints is extremely low, but the possibility of two people of the same age, weight, height, and walking posture, etc., is relatively higher. The most important point is that footprints may not show all the specificity. If only part of it is shown, the similarity is relatively high.
Of course, this is more than enough for the task force.
Confirming that the suspect is the suspect again, Jian Louyuan was very happy and stood on the other side of Jiang Yuan with his hands on his waist like Mu Zhiyang, with a gun in his holster.
Units like the Criminal Police Detachment are originally the highest criminal investigation units in the province or city. They handle more major and serious cases, which is very different from the grassroots front-line police units. Captains like Jian Louyuan occasionally have the opportunity to shoot. If they really encounter a case, they are not afraid to shoot.
Jian Yuan personally stepped forward to check the footprints.
By switching the light source with the survey lamp, you can see various traces left on the ground and walls.
Jiang Yuan chose the clearer ones and pointed them out. Someone took photos with a camera and collected evidence.
Jiang Yuan went around a lot. After looking at the whole house, he returned and said, "I didn't see any traces of the murder, but I can't rule out whether it was the first scene. In addition, there are footprints of multiple men in this house, and the female footprints are the victim and her sister."
Jian Louyuan responded and said, "After our people investigated and questioned in the supermarket, they determined that the victim Li Miaoyan had a boyfriend who drove an excavator. There was no report to the police afterwards. We have sent someone to invite him over."
Liu Jinghui immediately asked, "Isn't he in Lanyue City? Where is his work place?"
"I used to work in Lanyue City. I left a few days ago and returned to my hometown, which is a town in the neighboring city." Jian Louyuan said.
"Where is his excavator?"
"The excavator belongs to the company, and he is just the excavator driver. Before leaving, he told his coworkers and the foreman that his relatives in his hometown were having a party and he wanted to go back to attend. The foreman paid him his salary."
Liu Jinghui's questions followed one after another: "How is his financial situation? Did the foreman pay him the full salary? Did he deduct any money?"
"He paid more than 3,000 yuan. He deducted about 200 yuan. The foreman said that his financial situation should be average, a little better than Li Miaoyan, but he also has elderly parents and no savings."
Liu Jinghui snorted and said, "This person is a major suspect."
"Yes. I also think that he didn't leave early or late, but ran back to his hometown after Li Miaoyan was burned to death." Jian Louyuan obviously thought of this question, and his breathing was a little rapid due to excitement.
"Besides, doesn't he take care of Li Miaoyan's sister?" Liu Jinghui asked, "How long have they been together?"
"Three years, right?" Jian Louyuan said, taking out his mobile phone and looking at it, and then said, "Liu Chengming, now 36 years old, is five years younger than the victim. The victim's sister didn't have a very good impression of him. When she called the police, she mentioned that her sister and her boyfriend often quarreled. When the local police investigated, they also asked Liu Chengming..."
"In that case...wait and see?" Liu Jinghui looked at Jiang Yuan.
From Liu Jinghui's point of view, this case has begun to become ordinary. The current clues all point to Liu Chengming, so just wait until Liu Chengming is brought to justice before continuing to investigate. It is really unnecessary to rush to investigate other clues at this time, and it is more like a desperate attempt to seek medical treatment.
Jiang Yuan naturally agreed, and only said, "You go and rest first, I'll finish dealing with the scene here. I was going to scan it again."
He just took a rough look just now, and he couldn't be sure whether this was the first scene.
To make a real judgment, there are many points to investigate.
Logically speaking, the two victims, male and female, most likely did not go to Dongxi Lake voluntarily. Whether it was threats, killing, or other means, the victims' homes were the focus of suspicion.
In fact, most of today's vicious murders occur indoors.
Liu Jinghui hesitated for two seconds and said decisively: "Then it's all your fault. I'm going to take a nap first. I might have to use my brain later."
Liu Jinghui went out and went straight to the hotel, took a combat bath and then went to sleep.
He wasn't really that sleepy, but he couldn't do what Jiang Yuan could do. It is even said that when the case has advanced to this extent, Liu Jinghui believes that the next time he, the dragon knight, is most needed is after he arrests Liu Chengming and returns.
If Liu Chengming refuses to confess, it will still be very difficult to obtain enough evidence for this case.
Apart from anything else, just proving that the two corpses belonged to Li Miaoyan and Wang Youming would take a lot of effort - the level of evidence required during the investigation stage and the level of evidence required by the court are different.
The police must at least find evidence that the two people arrived at Dongxi Lake within the qualified time period, as well as the corresponding evidence chain. For example, surveillance videos or photos on the road, or the positioning of mobile phone signals, etc. Just the footprints at the scene, not to mention the difficulty of proving that the footprints are the same, even if proven, can only show that the two people have been to Dongxi Lake.
But footprints can be left long ago.
This may sound a bit nonsense, but that's what court evidence requires.
Therefore, the police still need to obtain confessions as much as possible, and the effectiveness of the evidence will be greatly improved.
From Liu Jinghui's point of view, Liu Chengming is only a key suspect. The possibility that he is the murderer is very high, but it is not absolute.
If Liu Chengming is not the murderer, then Liu Jinghui's next task will be very heavy.
By then, he would need to point out the way forward for Jiang Yuan.
As for now, Jiang Yuan can do whatever he wants, whether he wants dragon flames to wash away the ground or leave traces of melee.
…
10pm.
Liu Jinghui was woken up by the vibration of his cell phone. He rolled over and felt a little dizzy.
Looking at the time again, Liu Jinghui was speechless for a while. He thought he was not too sleepy, but he couldn't wake up even if he thought he would fall asleep.
"Hello." Liu Jinghui opened the call.
"Liu Chu. Liu Chengming brought him back and gave an explanation." Jian Louyuan's voice was tight, like a broken clamp.
Liu Jinghui was stunned: "Has it been detected? Did Liu Chengming commit the crime independently?"
"Yes."
"Okay." Liu Jinghui couldn't explain his emotions. As a policeman, he was naturally happy to have solved another murder case, but as a dragon knight, he had just gotten up and his emotions were indescribable.
"Liu Chu. Then I will send a car to pick you up?"
"Okay. By the way, what was the reason for the murder?"
Jian Louyuan's voice paused for a while and said: "According to Liu Chengming, on the night of the 9th, Li Miaoyan proposed to enroll her sister in a cram school. She still had 800 yuan left, and wanted Liu Chengming to take it. Liu Chengming suggested that the cram school was too expensive. I talked a lot with Li Miaoyan, but in the end he didn't come up with any money, so he was insulted by Li Miaoyan as a coward, a dog-like man, etc. "
Jian Louyuan: "Liu Chengming said in his own words that he really couldn't get 800 yuan at that time. If he wanted to get the money, he had to find the foreman to spend it. It was already night, and he had to ask for it the next day, and he might not get it until the third day. Money. Li Miaoyan scolded her very hard, and Liu Chengming was also angry, but not to the point of murder."
Jian Louyuan: "Subsequently, Liu Chengming was kicked out of the house. He had no choice but to find someone to borrow 800 yuan, and then went back to beg Li Miaoyan to let him in. It is said that he begged for a long time. After opening the door, he found Wang Youming lying on Li Miaoyan's bed. ”
"Just lie on the bed?" Liu Jinghui's scalp went numb after hearing this: "You are giving money to someone, and you are asking for money. Is it necessary?"
Jian Louyuan said: "Liu Chengming's statement is that the construction site is far away. If Li Miaoyan doesn't open the door, he will have to stay in a hotel outside, which will cost hundreds of dollars."
"You ended up blocking your concubine in the house?"
"Well, but Liu Chengming knew about Wang Youming's existence. But he had agreed with Li Miaoyan that Wang Youming could not come to the house. The three of them had a quarrel, and Wang Youming imitated Liu Chengming's words of begging for mercy outside the door. Liu Chengming became angry and took out his wallet Carrying knives, he then tied up the two victims.”
Liu Jinghui was listening and thinking, feeling that his brain was running out: "Then does Wang Youming know about Liu Chengming? Does he agree?"
"Wang Youming joined later, and of course he knew Liu Chengming. He was a carpenter. He was very busy when he was working, and he didn't have time to find Li Miaoyan. He usually finished a job and invited Li Miaoyan to stay for a few days. Of course, the two of them People can’t stand each other either.”
