Snapped!
Su Shanming lit a cigarette without being exposed to secondhand smoke.
He is a veteran who has been a member of the task force for 10 years. The several criminal police officers present may not be able to solve the case, but one look at the looks of his colleagues will tell which butt he is sticking up today.
Snapped.
Lang Heng also lit a cigarette, using the Zhonghua that Liu Jinghui had saved and placed on the table.
clap clap!
In the meeting room 4303, smoke once again dominated the mainstream, forcing the ventilation fan to hum and blowing the dry grass outside. How could ordinary flowers and plants withstand the destruction of nicotine? They would have died long ago.
Su Shanming took another sip of tea before saying, "I was the one who looked into my daughter's clues."
This is also a very normal approach. Ten years ago, the requirement was that murder cases must be solved, and the requirement was even higher than it is now. The resources invested by the police, especially human resources, are extremely sufficient. If two people died, there will definitely be police officers following up on the other person's interpersonal relationships.
Su Shanming spoke a few more times, and then continued, "The little girl studied at our city's No. 3 Middle School. She should have been in the second grade at the time. When I was investigating, I first asked the school's teachers, then some classmates, and then our colleague's father. I can't remember the specific content and what was said at the time. In our current terms, the little girl should have had an ambiguous object."
"It's normal to have one or two crushes in the second year of junior high school." Huang Qiangmin was more trying to ease his emotions.
Seeing that the political commissar had entered the trench, Mu Zhiyang immediately sent himself off: "When I was in junior high school, all the girls in my class were my secret crushes."
"Well... the girl's ambiguous object, in fact, it's not that ambiguous, they just called each other privately, and they had a good impression of each other. He is a classmate from the next class. He is tall. Compared with junior high school students, he is tall and thin. He is over 1.75 meters tall in the second year of junior high school. He has learned dance and is good at speaking. His parents are senior intellectuals." Su Shanming briefly explained the situation, and then said: "I also investigated it carefully at the time. Personally, I feel that this classmate should not be capable and would not commit such a vicious case, nor is there any need."
"Does he have the ability to strangle an adult woman like Sui Yingxue?" Jiang Yuan said this because Sui Yingxue has two children and is very active in her daily life. She is a bit plump, weighing more than 110 pounds. Although she still cannot compete with the strength of a man, she still has some resistance when facing a teenager.
Su Shanming recalled for a moment, shook his head, and said: "The boy was a very thin boy. Even if he could strangle an adult woman, it was not repressive."
"Then we need at least two people." Jiang Yuan looked at Liu Jinghui.
Liu Jinghui nodded: "Teenagers are not intimidating enough. Even if they hold a knife, they still need pure force to control Sui Yingxue and her daughter. It is impossible to threaten them with a knife and make them submit."
Su Shanming took another puff of his cigarette and said, "After I learned about the girl's ambiguous partner, I wrote a note in the investigation file and never wrote anything else about it afterwards. The social atmosphere at that time was still quite conservative, so I thought..."
"Since it is a clue that has been eliminated, it is enough to mention it." Lang Heng waved his hand and did not let Su Shanming explain any more. He turned to Liu Jinghui and said, "Do you want to continue investigating this line? There is another question here. If it is the girl's boyfriend, or a crush, or a pursuer, will it lead to murder? At least it is unlikely that it will lead to murder quietly. Moreover, the mother hid her son. If the girl has problems with her interpersonal relationships, she should either not hide him or hide both of them."
"This is indeed one of the considerations." Liu Jinghui frowned as he spoke, but the corners of his mouth couldn't help but show a little happiness.
This case is the one that really requires reasoning!
Two murderers and multiple investigative directions. Each direction has hope, but it also seems to be a dead end... This is a case that requires careful analysis using logical reasoning.
"As for the little girl, I think it's necessary to reconfirm it." Liu Jinghui restrained his expression and said, "Of course, I'm not saying that there are big doubts in this direction, but I think that the investigation in this direction was not sufficient at the time. Of course, of course, this was also limited by the environment at the time. The world of teenagers is separated from the world of adults. Even if the police inquire, some teenagers may not explain it clearly for various reasons..."
After Liu Jinghui emphasized, he said, "Now it has been 10 years. The child who was 14 years old back then is now 24 years old. I think this is actually a good opportunity. Things that seemed extremely difficult in junior high school, even if they were very shameful or scary, should no longer be a problem when I think about it now. If I ask them again, maybe we can gain something?"
This time, Su Shanming couldn't help but nod: "Indeed, the issues that were difficult to talk about back then should be able to be discussed now. I will continue to follow up on this."
Liu Jinghui looked at Lang Heng. He was still an expert in the provincial department and did not need to command the people in Changle City.
Lang Heng nodded and said, "Okay, Shanming, you continue to follow up."
Reasoning must also be based on evidence. Liu Jinghui's continuous advancement of the investigation direction also requires the help of other criminal police to implement it.
After discussing this line, Liu Jinghui was slightly excited. He sorted out his thoughts and said, "From a human perspective, the victim's husband, who was the first suspect before, I think you have also checked his network of relationships."
"That's for sure." Lang Heng nodded slightly.
"However, you probably had limited trust in the suspect back then. I think it's necessary to take out his confession again and conduct an in-depth investigation." Liu Jinghui proposed the general direction this time, which meant that another 20 police officers would have to spend about a week on long shifts.
"Okay." Lang Heng agreed immediately.
"Captain Jiang, where are you?" Liu Jinghui looked at Jiang Yuan.
"I don't have a complete idea right now." Jiang Yuan replied, then looked at Liu Jinghui and said, "If I have to say, I suggest doing trace evidence, do more, and take more samples."
"How much?" Lang Heng gritted his teeth.
"Let's do a screening of all the collected evidence. I'll mark some of the evidence so that we can take samples from a few more spots later." Jiang Yuan replied.
Anyway, if you don't have any ideas, just cast a wide net. This is actually Liu Jinghui's strategy. He has handled countless cases, big and small, from the provincial department to the local level. Many major cases were actually solved using this shameless method.
Jiang Yuan followed suit, and instantly he went from having no ideas to having no ideas at all.
Compared to DNA, trace evidence targets substances other than the human body, but its effectiveness and sensitivity are comparable to DNA.
"Do all of them? The cost of doing a trace of physical evidence now is at least 500 yuan. The amount of physical evidence left over from the 430 case, if we do all of them, wouldn't it cost thousands or even tens of thousands of pieces?"
"Then let's mark the evidence first, and then slowly expand it later." Jiang Yuan expressed his understanding very reasonably. It is slow to collect trace evidence, and it has to be done in batches.
"I'll try to do more." Lang Heng guessed Jiang Yuan's idea and pretended not to know. Although he was the payer, he had to admit that the plans proposed by Liu Jinghui and Jiang Yuan were very practical.
Whether it is Liu Jinghui's ideas or Jiang Yuan's plan for trace evidence, they have broken through the constraints of the previous two task forces. It has to be said that this is the most promising direction of investigation.
