National Forensic Doctor

"It is not easy to leave no footprints at the eucalyptus discovery site."

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 use plastic bags or newspapers to wrap the shoes, there will always be traces when they land."

"Oh...that's right. Then Wang Zhong's judgment is not bad." The police officer in charge smiled and decided to believe Wang Zhong.

Liu Wenkai also recalled the incident, saying: "We investigated at the time and found that apart from the door showing signs of invasion, we found no other entrances and exits to the incident. In addition to messy clothes, the main items missing in the room were cash and Jewelry, some valuable electrical appliances, including computers, and alcohol were not missing, so there was initial suspicion of theft."

"Indeed, the person who called the police was a teenager?" Jiang Yuan agreed. Adolescents are 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 piece is made by the artist with all his strength." Jiang Yuan felt that this piece 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, and 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 check the situation of the reporter again. It's been half a year and see if there is any change."

If it was really a case of self-imposed theft, the boy's expenses, etc., should have increased in the past six months. Even if it doesn't show up on a daily basis, you can always get some indication by checking his WeChat, shopping records, ticket purchase records, room opening records, etc.

If you haven't already, you probably don't need to think too much about committing theft.

Without Liu Wenkai's orders, the policeman in charge responded and went to investigate.

Jiang Yuan put the book aside and looked at other items.

Extraordinary conclusions require extraordinary evidence.

The most common judgment is that the person is under guard and has committed theft. Even if the previous police officers 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 we have entered into unconventional judgment.

This is why big hospitals prefer patients to have their examinations repeated. Because when patients arrive at a large hospital, conventional illnesses have often been ruled out. To draw an unconventional conclusion, naturally more evidence is needed.

The police behind them brought in other dossiers.

Jiang Yuan felt that reasoning and the like were a bit laborious, so he picked up fingerprints and other pieces of information and did them first.

This kind of eucalyptus is as comfortable as it is comfortable. Someone has already taken care of 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 bugs, it is not necessarily possible to match the fingerprints...

Jiang Yuan picked up those fingerprints with difficulty level 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.

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

"Catch him back for interrogation." Jiang Yuan found a suspect with one person, and it felt like it was almost done.

This kind of kid, no matter whether the person brought back is the real owner or an outsider, it will be basically clear after the first trial. There is no need to make it extra complicated.

Liu Wenkai responded and happily arranged for people to execute it.

Jiang Yuan continued to make another footprint, still using a similar process.

Everyone in the Second 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 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 crimes of the Second Squadron are all relatively serious compared to the county bureau. For example, for more common burglaries, the sentences start at three years. If you are a habitual offender or a repeat offender, it is normal for an aggravating item to be added to the sentence for an additional two years.

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 made five hams in one go. Seeing that it was almost time to get off work, he stood up, stretched, and said with a smile: "Let's 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.

In the playground of the police dog squadron, Da Zhuang is exercising.

Suddenly, Da Zhuang, who was doing an obstacle course 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 giving 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 took Da Zhuang and ran a few laps side by side with one person and one dog.

After warming up a little, Jiang Yuan took Da Zhuang for a walk. Police dogs only eat one meal a day, so today’s quota has 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... it sucks...

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...sucking..."

…

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 software has been overturned.

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

The policeman 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 that came to Jiang Yuan's mind was Mr. Liang Shang. If it were an ancient house, prisoners 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 the prisoner again, took out a few of them, and said: "It seems like the prisoner must have worn this family's shoes." .”

A photo he took out showed 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 house are all the shoe prints of his own family, but if analyzed carefully, The same footprint has multiple forms..."

When Jiang Yuan said this, he 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 unlikely. There are a lot of relatively fresh footprints from 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 in themselves. It’s all because the family’s room is big enough, and the boy is lazy enough at home to not sweep or mop the floor.

But in any case, given such a footprint, it is still difficult to break it. The blue slippers must be found before this clue can continue.

"I'm going to find these slippers." The police officer in charge didn't have much to say and just left with the person.

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 asked with some concern: "It's been half a year, can we still get the DNA of the prisoner?"

"Let's see. If he was not wearing socks and his shoes were not washed, he would have a higher chance of getting it. 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.
