Chapter 608 Slippers
"It is not easy to leave no footprints at the scene of the crime."

Jiang Yuan flipped through the photos, talking like a chat.

The policeman in charge nodded: "That's right, so we guess, did the murderer use something to wrap his feet?"

He dragged his voice and looked at Jiang Yuan, as if he wanted to get an answer.

Jiang Yuan looked at the photo and replied: "It's not like, there are no abnormal footprints. If you use plastic bags or newspapers to wrap the shoes, there will always be traces when they hit the ground."

"Oh...that's it. Then Wang Zhong's judgment is not bad." The policeman in charge smiled and decided to trust Wang Zhong.

Liu Wenkai also recalled this case, saying: "We investigated at the time and found no other entrances and exits to the scene of the crime except for the door showing signs of intrusion. In addition to the messy clothes in the room, the main lost items were cash and jewelry. , Some valuable electrical appliances, including computers and alcohol, were not lost, so at the beginning, there were suspicions of self-stealing."

"Indeed, it was a teenager who called the police?" Jiang Yuan agreed.Teenagers are the age to challenge the world and authority, and the law itself is a part of the world and authority.

Liu Wenkai nodded, and said: "If it was the son of the Shen family who did it, he should be able to find out where the money went. 20 in cash, and so many gold and silver jewellery, but no clues were found. .”

Jiang Yuan nodded slowly.

Although in ordinary cases, the means of the police are relatively limited, but it depends on who they are compared with.

It is very difficult for ordinary students to just hide the money. As for selling the stolen goods, it is even more difficult. It is hard to say that there is no rumor about it.

"So, every case is made by the perpetrators with all their efforts." Jiang Yuan felt that this case was a bit interesting, and couldn't help but sigh with emotion.

Liu Wenkai nodded with a smile: "It's like a woman. Every woman has her soft and lovely side. Ordinary girls also have her unique beauty. Every girl is different, regardless of low price. market, high price market."

Jiang Yuan looked up at Liu Wenkai: "Your translation is somewhat misinterpreted... Let's look at the case. Let's check the reporter's situation again. It's been half a year and see if there is any change."

If it's really a case of self-stealing, the boy's expenses and so on should all have increased in the past six months.Even if it doesn't show up in daily life, check his WeChat, shopping records, ticket purchase records, room opening records, etc., it can always be reflected.

If you haven't, you probably don't need to think about it too much.

Without Liu Wenkai's instructions, the police in charge of the case responded and went to investigate.

Jiang Yuan put this case aside and looked at other cases.

Extraordinary conclusions require extraordinary evidence.

Guarding and stealing is the most routine judgment. Even if the police in front have checked along this line, they still have to check again when they arrive at Jiang Yuan's place.Because excluding this conclusion means entering into unconventional judgments.

This is why large hospitals prefer patients to have their examinations repeated.Because when the patient comes to a large hospital, the conventional symptoms are often ruled out.To draw an unconventional conclusion, naturally more evidence is needed to support it.

The police at the back brought other case files.

Jiang Yuan felt that reasoning and the like were a bit laborious, so he picked up fingerprints and other cases and did it first.

This kind of case is as comfortable as it is comfortable, and other conditions have been completed by someone, and it can be purely technical.

The trace inspection in Ningtai County is still Yan Ge and Wang Zhong, and their level is still the same. Faced with various small cases, they may not be able to compare with fingerprints...

Jiang Yuan just picks up the fingerprints with difficulty LV1.5 and above.

For fingerprints with a lower difficulty value, Yan Ge and Wang Zhong supposedly had a relatively high probability of making them, and Jiang Yuan didn't do much research.

The two cases involved more than a dozen fingerprints. If the difficulty was in line with Wang Zhong's ability, he would have to do it for an hour or two.

From Jiang Yuan's words, plus the more than ten minutes of turning on the computer and software, it took a quarter of an hour to complete the comparison.

"Catch it back and interrogate." Jiang Yuan felt that it was almost enough to assign a suspect to a case.

For such a small case, no matter whether it is the owner or an outsider who is brought back, it will be clear at the first trial.There's no need to make it any more complicated.

Liu Wenkai responded, cheerfully arranging for people to carry it out.

Jiang Yuan continued to do another footprint case, which was still a similar process.

The Second Squadron was elated and began to feel the goodness of the limited edition.

Jiang Yuan smiled, actually quite happy in his heart.

Compared to running outside from dawn to dusk, smoking and squatting all day long, or running around to arrest people, sitting in front of the computer to arrest people is also quite good.

Moreover, the cases of the Second Squadron are all serious cases compared to the county bureau, such as ordinary burglary and the like, and the sentence starts from three years.If it is a repeat offender, or a repeat offender, it is normal to add an aggravated item and add two years.

Three to five years does not sound like much, but it is already very severe in terms of criminal law, and the crackdown on ordinary criminals is also relatively high.

Jiang Yuan did five cases in one go. Seeing that it was almost time to get off work, he got up and stretched, and said with a smile, "It's better to come here first today. I'll go play with Da Zhuang for a while."

"Okay, okay." Liu Wenkai quickly agreed, and went out personally to send Jiang Yuan downstairs to the police dog squadron.

Da Zhuang is exercising in the playground of the Police Dog Squadron.

Suddenly, smelling Jiang Yuan's scent, Da Zhuang, who was doing an obstacle course, turned around in the air and looked in Jiang Yuanlai's direction.

Jiang Yuanyuan waved and smiled.

Li Li also saw him, wiped off her sweat, said hello, and said with a smile, "Would you like to give the two of you some time to play?"

"Thank you sister." Jiang Yuan took the leash.

Da Zhuang replied with a "bark", as if thanking him.

Li Li glared at Da Zhuang, his expression was similar to Da Zhuang's.

Jiang Yuan led Da Zhuang and ran side by side for a few laps.

After warming up a bit, Jiang Yuan took Da Zhuang for a walk again.Police dogs only eat one meal a day, so today's quota has already been used.

Da Zhuang knew it himself, but he was still very happy that Jiang Yuan played with him.

LV5 or LV6 dog rice, even if you can't eat it, it's not a big deal... suck...

When Jiang Yuan left for the last time, Da Zhuang looked at his back and was drooling.

Li Li looked helpless for a while, wiped Da Zhuang's mouth first, and said: "You are really worthless, aren't you just a piece of shit... suck..."

……

The next day.

The police in charge of "Jinding Mingyuan" came back and reported: "There is no evidence that the reporter was guarding and stealing."

This means that the easiest way to start the case has been overturned.

"In that case...is it okay for the husband and wife of this family?" Jiang Yuan has read the file, but he still needs to confirm it.

The policeman in charge nodded, and said: "I have also investigated the situation of the couple, so it is only now. Basically, because this family is a demolition household, they are not very short of money. Their net worth far exceeds this figure. There is no strange income, um...the two of them can't get any benefits from this theft, they look like ordinary people..."

"There are no other people's footprints in the room..." The first thing Jiang Yuan thought of was Mr. Liang Shang.If it was an ancient man's house, the criminal could go up and down without falling to the ground, so as to avoid being discovered.

Jinding Mingyuan obviously does not have such conditions.

Jiang Yuan actually had some thoughts in his heart. After confirming this, he looked at the photos of the case again, took out a few of them, and said: "From this point of view, the criminal should have worn the shoes of this family."

A photo he took out was the family's shoe cabinet.

Jiang Yuan pointed to the slippers among them, and said: "In terms of the living habits of this family, slippers should be worn randomly, and there is no fixed person to wear them. So the footprints in his house are all his own family's shoe prints, but if you analyze carefully, The same footprint has multiple forms..."

Jiang Yuan found a pair of blue shoes at this point, and said: "The other shoes are worn by the family of three. There are three types of footprints. There are four types of blue men's slippers."

"Where are the guests?" The policeman in charge suddenly thought of this doubt.

"Maybe. It's unlikely. There are a lot of fresh footprints of the blue slippers." Jiang Yuan shrugged and said, "Now that I'm stuck here, let's see what I can get out of these shoes." No."

The footprints and clarity found indoors are not very good in themselves.It all depends on the family's room being big enough. In addition, the boys are lazy at home and don't sweep or mop the floor.

But in any case, it is still difficult to solve the case simply by giving such footprints.The pair of blue slippers must be recovered before this clue can continue.

"I'm going to find this slipper." The policeman in charge didn't have much to say, and was about to leave with him.

Jiang Yuan warned: "The DNA will be collected when you bring it back, and you should be careful not to contaminate the evidence. Don't call in advance, and take the DNA of the husband and wife on the spot."

"Okay." The policeman in charge responded.

Liu Wenkai asked with concern: "It's been half a year, can we still get the criminal's DNA?"

"Look. If he hadn't worn socks and his shoes hadn't been washed, he would have had a better chance of getting them. If he wore socks...if he sweated, he should be able to leave something..." Jiang Yuan analyzed very carefully.

Liu Wenkai curled his lips: "Don't wash the slippers at home for half a year? The family's habits are dirty enough."

"How often do you wash your slippers?" Jiang Yuan was suddenly a little curious.

"Slippers...the slippers don't seem to have been specially washed before." Liu Wenkai hesitated for a moment, and then entered the long exam time.
