"It is not easy to leave no footprints at the crime scene."
Jiang Yuan flipped through the photos and talked as if chatting.
The police officer in charge nodded: "That's right, so we guess, did the murderer use something to wrap his feet?"
He spoke in a long tone and looked at Jiang Yuan, as if he wanted to get an answer.
Jiang Yuan looked at the photo and replied: "No, there are no abnormal footprints. If you wrap the shoes with plastic bags or newspapers, 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 believe Wang Zhong.
Liu Wenkai also recalled the case and said: "We investigated at the time and found that except for the signs of invasion on the door, no other entrances and exits to the crime scene were found. In addition to messy clothes in the room, the main items missing were cash and jewelry.
, some valuable electrical appliances, including computers, and alcohol were not lost, so there was early suspicion of tampering."
"Indeed, the person who called the police was a teenager?" Jiang Yuan agreed. Teenagers are at the age when they challenge the world and authority, and the law itself is part of the world and authority.
Liu Wenkai nodded and said: "If it was the son of the Shen family who did it, we should be able to find the whereabouts of the money. 200,000 in cash, and so many stolen gold and silver jewelry... but no clues were found.
."
Jiang Yuan nodded slowly.
Although in ordinary cases, the police's methods are relatively limited, it depends on who you compare them with.
It is very difficult for ordinary students to just hide the money. As for selling the stolen money, it is even more difficult. It is difficult to say that there is no news about it.
"So, every case is the result of the perpetrators' best efforts." Jiang Yuan felt that this case was a bit interesting and couldn't help but sigh.
Liu Wenkai smiled and nodded: "It's like a woman. Every woman has her delicate and lovely side. Ordinary girls also have their own unique beauty. The girls in each place are different, regardless of the low price.
Market, high-priced market.”
Jiang Yuan raised his head and looked at Liu Wenkai: "Your translation is somewhat misinterpreting my words... Let's look at the case. Let's check the situation of the reporter again. It's been half a year and see if there is any change."
If it is really a self-inflicted theft, the boy's expenses, etc., should have improved in the past six months. Even if it is not reflected in daily life, check his WeChat, shopping records, ticket purchase records, room opening records, etc.
There is always some reflection.
If you haven't already, you probably don't need to think too much about committing theft.
Without Liu Wenkai's instructions, the policeman in charge of the case responded and went to investigate.
Jiang Yuan put this case aside and looked at other cases.
Theft is the most conventional judgment. Even if the previous policemen checked along this line, they still have to check again when they get to Jiangyuan. Because if this conclusion is ruled out, it means that they have entered into an unconventional judgment.
went.
This is why large hospitals prefer patients to have re-examinations. Because when patients come to large hospitals, conventional diseases have often been ruled out. To draw an unconventional conclusion, more evidence is naturally needed.
The police behind me brought in other case files.
Jiang Yuan felt that reasoning and the like were a bit laborious, so he picked up cases such as fingerprints and worked on them first.
This kind of case is as comfortable as it is comfortable. Someone has already completed the other conditions, so you can just do the technical work.
Ningtai County's fingerprint inspection is still carried out by Yan Ge and Wang Zhong, and the level is still the same. Faced with various small cases, it is not necessarily possible to match fingerprints...
Jiang Yuan just picked those fingerprints with difficulty level 1.5 and above.
Yan Ge and Wang Zhong supposedly had a relatively high probability of producing fingerprints with a lower difficulty level than this, and Jiang Yuan did not do much research.
The two cases involved more than a dozen fingerprints. Even if the difficulty met Wang Zhong's ability, it would have taken him an hour or two to do it.
In Jiang Yuan's words, plus the more than ten minutes of running the computer and software, it took a total of a quarter of an hour to complete the comparison.
"Let's bring him back for questioning." Jiang Yuan felt that it was almost done when one suspect was assigned to each case.
In such a small case, whether the person brought back is the real owner or an outsider, it will basically be clear after the first trial. There is no need to make it particularly complicated.
Liu Wenkai responded and happily arranged for people to execute it.
Jiang Yuan went on to do another footprint case, still with a similar process.
Everyone in the No. 2 Squadron was very excited and began to feel how good the limited edition was.
Jiang Yuan smiled, actually feeling quite happy.
Rather than waking up early in the morning and running around late at night, smoking and squatting all night long, or rushing around and working hard to catch people, it is good to sit in front of the computer and catch people.
Moreover, the cases of the Second Squadron are all major and serious cases compared to the county bureau, such as more common burglaries, etc., which all have a starting sentence of three years. If it is a habitual offender or a repeat offender, one aggravating item will be added, and more
Two years is normal.
Three to five years may not sound like much, but it is actually very severe in terms of criminal law, and the crackdown on ordinary criminals is also relatively high.
Jiang Yuan worked on five cases in one breath. Seeing that it was almost time to get off work, he stood up, stretched, and said with a smile: "I'll just stay here for today. I'll go play with Da Zhuang for a while."
"Okay, okay." Liu Wenkai agreed quickly and went out in person to send Jiang Yuan to the police dog squadron downstairs.
Da Zhuang is exercising in the playground of the police dog squadron.
Suddenly, Da Zhuang, who was doing obstacle course running when he smelled Jiang Yuan's scent, turned around in the air and looked in the direction Jiang Yuan came from.
Jiang waved from afar, smiling.
Li Li also saw him, wiped her sweat, said hello, and said with a smile: "How about I give you two brothers some time to play."
"Thank you, sister." Jiang Yuan took the traction rope.
Da Zhuang responded with a "woof, woof" sound, as if thanking him.
Li Li glared at Da Zhuang, with an expression similar to Da Zhuang's.
Jiang Yuan led Da Zhuang, and they ran a few laps side by side.
After warming up a little, Jiang Yuan took Da Zhuang for a walk. The police dog only ate one meal a day, so today's quota had already been used.
Da Zhuang himself knew this, but he was still happy that Jiang Yuan played with him.
Even if you can’t eat the LV5 or LV6 dog food, it’s not a big deal…suck it…
When Jiang Yuan finally left, Da Zhuang looked at his back and drooled.
Li Li looked helpless for a while, then wiped Da Zhuang's mouth first, and said: "You are really worthless, aren't you just dog food... suck..."
…
The next day.
The policeman in charge of "Jinding Mingyuan" came back and reported: "No evidence was found that the reporter was guarding and stealing."
This means that the easiest way to start the case has been overturned.
"In this case... is it okay for the couple in this family?" Jiang Yuan had read the file, but still wanted to confirm it.
The police officer in charge nodded and said: "I have also investigated the situation of the couple, and that's why I'm here now. Basically, because this family is a demolition household, they are not very short of money, and their net worth far exceeds this figure. Recently,
There is no strange income, well...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 were an ancient house, the criminal could move up and down without falling to the ground to avoid being discovered.
Jindingmingyuan obviously does not have such conditions.
Jiang Yuan actually had some ideas in mind. After confirming this, he looked at the photos of this case again, took out a few of them, and said: "It seems like the criminal must have worn this family's shoes."
A photo he took out was of the family's shoe cabinet.
Jiang Yuan pointed to the slippers among them and said: "In terms of this family's living habits, the slippers should be worn randomly and not worn by one person. Therefore, the footprints in his home are all the shoe prints of his own family, but if analyzed carefully,
The same footprint has multiple forms..."
At this point, Jiang Yuan found a pair of blue shoes and said, "The other shoes are worn by this family of three. There are three types of shoes. This pair of blue men's slippers has four types."
"Where are the guests?" The police officer in charge suddenly thought of this doubt.
"Maybe. It's not very likely. There are a lot of relatively fresh footprints of these blue slippers at the scene." Jiang Yuan shrugged and said, "Now that I'm stuck here, let's see what we can dig out of these shoes first.
No."
The footprints and clarity found indoors are not very good. This all depends on the family's room being large enough, and the boy being lazy at home and not sweeping or mopping 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 found before this clue can be continued.
"I'm going to find these slippers." The police officer in charge didn't say much and just took the person and left.
Jiang Yuan warned: "You need to collect DNA when you bring it back. Please be careful not to contaminate the evidence. Don't call in advance. We will collect the couple's DNA on site."
"Okay." The police officer in charge responded.
Liu Wenkai said with some concern: "It's been half a year, can we still get the DNA of the criminal?"
"Let's see. If he wasn't wearing socks and his shoes weren't washed, he would have a higher chance of getting them. If he was wearing socks...if he was sweating, he should be able to leave something behind..." Jiang Yuan analyzed
Very carefully.
Liu Wenkai pouted: "Don't you wash your slippers for half a year? This family's habits are quite dirty."
"How often do you wash your slippers?" Jiang Yuan suddenly became curious.
"Slippers...it seems that the slippers have not been specially washed before." Liu Wenkai hesitated for a moment, and then entered the long examination time.
