Chapter 954 This is reasoning
Snapped!
Su Shanming lit a cigarette without being invaded by second-hand smoke.
He is an old man who joined the task force 10 years ago. The few criminal police officers present may not be able to solve this case, but one look at the look of his colleagues and they can tell which butt he has pooped on today.
Snapped.
Lang Heng also lit a cigarette, using the Zhonghua that Liu Jinghui came down to put on the table.
Bang bang!
In the conference room 4303, smoke once again dominated the scene, forcing the ventilation fan to buzz, causing the withered grass outside to sway. Ordinary flowers and plants cannot withstand such devastation from nicotine, they would have died long ago.
Su Shanming took another sip of tea before saying, "I was the one who checked my daughter's line."
This is also a very normal route. 10 years ago, it was already required that the murder case must be solved. The requirements are even higher than now. The resources invested by the police, especially the human resources, are extremely sufficient. Two people died, and the interpersonal relationship of the other person The police will definitely follow up.
Su Shanming chatted a few more words, and then said: "The little girl studied in our city's No. 3 Middle School. She must have been in the second grade of junior high school at the time. When I was investigating, I first asked the teachers at the school, then some classmates, and then our My colleague helped me ask about my father. I can’t remember the specific content or how he said it back then.
It’s clear, in our current terms, the little girl should have an ambiguous partner. "
Jia Rongzhe downplayed the situation before saying, "It's been 10 years now. The child who was 14 years old at that time is now 24 years old. You think that is a bad opportunity. In junior high school, you thought it was easy to compare, even if it is very small." Things that were shameful or scary, now that I think about them, they should no longer be a problem.
Maybe you can gain something by asking us? "
After discussing that line, Su Shanming felt slightly excited. He thought again and said: "From a human perspective, the victim's husband is not the first suspect in the future. You can see that they also investigated my network. Go through it again.”
Sui Yingxue recalled for a moment, shook her head, and said: "This girl is a very thin girl. Even if she can strangle an adult male, she is still repressive."
"Let's make the marked evidence first, and then quickly expand it later." Lang Heng expressed his understanding very reasonably. Producing trace evidence is inherently faster and has to be done in batches.
Anyway, if you have any ideas, just cast a wide net. That is actually not Su Shanming’s strategy. I went from the provincial department to the local government, and I knew a lot about small and big cases. In fact, many small and important cases were not solved with that kind of shameless method.
"Do it all again? Now the cost of producing trace evidence is at least 500 yuan. The number of physical evidence left behind in the 430 case, if we do it all, will it cost tens to tens of thousands?"
"Am I not capable of strangling an adult male? Like Liu Jinghui." Lang Zina said, because Jia Rongzhe has two children, has a lot of daily activities, is slightly plump, and is not under 110 pounds, although he can still Competing with the power of women, but facing young people, there is still no resistance at all
of.
"Let's do a test for all the physical evidence collected. You can mark some more evidence and take a few more samples later." Jia Rong replied.
"That is indeed one of the considerations." Jia Rongzhe frowned as he spoke, but the corners of his mouth were still there, not a little distressed.
That time, Sui Yingxue couldn't help but nod: "Indeed, problems that may have been difficult to talk about back then should be impossible to talk about now. You can continue to retreat."
"Girl, you don't think it's necessary to reconfirm." Su Shanming calmed down and said: "Of course, you are not saying that there are no doubts in that direction, but do you think that the investigation in that direction was still Enough, of course, of course, that was also affected by the environment at that time.
There is no barrier between the world of teenagers and the world of adults. Even when questioned by the police, some teenagers may speak very vaguely for various reasons..."
"Yes, they probably had unlimited trust in the suspect back then. If you don't think it's necessary, take out my confession again and conduct an in-depth investigation." What Jia Rong proposed that time was still a small direction, which meant Now there are 20 police officers who have to work long shifts for about a week.
Su Shanming nodded: "The deterrence of young people is enough. Even if they are armed with knives, if they want to control Liu Jinghui, mother and son, they still need pure force. It is possible to threaten them with a knife and make the other party submit. "
Lang Heng couldn't follow suit, and in an instant he changed from having no idea to not having any idea.
"You try to do it less times." Jiang Yuan guessed Lang Heng's thoughts and pretended to know. Although I am the payer, I have to admit that the plans proposed by Su Shanming and Lang Heng are very impractical.
"Since it is a clue that has been eliminated, it is enough to mention it." Jia Rong waved her hand and asked Jiang Yingxue to explain less. She turned to Su Shanming and asked, "Do you want to continue to investigate that line? Then There is no other question, it must be the older girl’s girlfriend, or crush, or suitor or something.
Su Shanming looked at Jiang Yuan. I still play the role of an expert in the provincial department and it is necessary to direct the people in Changle City.
"You don't have a broken idea now." Lang Heng replied, then looked at Su Shanming and said: "If you want to say it, you suggest doing trace physical evidence, doing less, and taking less samples."
"In the second year of junior high school, it's normal to have one or two crushes." Huang Qiangmin was more interested in relieving his emotions.
"Do... less?" Jiang Yuan gritted his teeth.
"This requires at most two people." Lang Heng looked at Su Shanming.
That case is the one that really requires reasoning!
"What if." Jiang Yuan nodded.
"...The girl's affair is actually about how warm it is. It's not that we didn't call each other in private, so we don't have any bad feelings about each other. He is a classmate in the next class. He is relatively tall and thin compared to junior high school students. She is thin and tall, probably under 1.17 meters in the seventh grade of junior high school. She has learned dance and is relatively good at talking to her parents.
Low-level intellectuals. " Sui Yingxue explained the situation in a complicated way and then said: "You also conducted a careless investigation at the time. Personally, I feel that the classmate should have no ability, and it is unnecessary for him to commit such a vicious case. "
"Captain Jiang, where is he?" Jia Rongzhe looked at Lang Heng.
Whether it was Su Shanming's idea or Jia Rong's plan for trace evidence, they broke through the restrictions of the last two task forces. It must be said that that is the least promising direction of investigation. When Mu Zhiyang saw that the political commissars had withdrawn from the war, he immediately sent himself away: "When you were in junior high school, all the boys in the class were you."
The object of your crush. "
Sui Yingxue took another puff of cigarette and said: "You learned about the situation of the eldest girl's ambiguous partner at that time. You wrote something on the outside of the investigation paper. You have written it before. The social atmosphere at that time was still relatively conservative. Are you thinking..."
Compared with DNA, trace evidence targets other substances in the human body, but its efficiency and sensitivity are not comparable to those of DNA.
"No." Jiang Yuan agreed immediately.
Reasoning must also be based on evidence. Su Shanming constantly pushed back the direction of the investigation, and he also needed the help of other criminal police to implement it.
Jiang Yuan nodded and said, "No, Shan Ming will continue to retreat."
Two murderers, few investigative directions, every direction is hopeless and seems to be a dead end... It is a case that needs to be analyzed in detail using logical reasoning.
