Many murders.
In fact, it is very difficult to directly identify the suspect because the murderer will consciously avoid the surveillance eyes.
basically.
Useful clues are extracted through the bodies of the deceased, the crime scenes, interrogations of relevant personnel, etc., and then a range is defined for screening.
After finding a suspect who may have committed a crime.
Then detailed comparison and interrogation will be carried out to identify the final murderer.
This is an alternative method of exclusion.
It is currently used quite frequently in criminal investigation and solving cases.
......
now.
After listening to Su Ming's analysis and the characteristics of the murderer he had screened out, Xu Changsheng nodded in agreement.
"We really can't waste any more time."
"Although no definitive clues have been found yet, many detailed speculations can indeed support the first screening."
"It will be beneficial to carry out subsequent work if we can eliminate the suspicion of the staff of Shude Middle School as soon as possible or identify the possible criminal suspects."
"Okay, I'll ask the technical department to check the staff of Shude Middle School."
"We must find possible suspects!"
Speaking of this.
Xu Changsheng looked at the skinny dog opposite him and asked slowly while tapping the table.
"Skinny dog."
"Although you have explained a lot, I suddenly remembered a question."
"You said earlier."
"This criminal organization controls at least 50% of the drug sales chain in Dragon Country, but you haven't even seen the online leader. How can you come to this conclusion?"
"Besides."
"It's really strange that such a large drug trafficking organization could hide for so long, right?"
The skinny dog sitting on the interrogation chair showed a somewhat frightened look and said with certainty.
"Officer, fifty percent is my guess."
"But I feel..."
"If you dig deeper, the specific shares and trading chains you find out may be even more shocking than what I said."
"As for how I got the information, I can only say that although we are not as good as the police, we drug dealers also have our own sources of information."
"When I was targeted again, I thought about escaping and getting rid of them, but the first thing I had to do was to determine how big their organization was."
"So the next day I immediately used all my connections to ask my friends in the surrounding cities who were poisoning dogs if they had any channels to buy dog poison with a purity of more than 95 percent."
"In the end, half of my friends answered me...yes!"
"Except for that organization, I think no one would be willing to buy Xiaobai of such high purity."
"As for why we were able to keep it a secret for so long, maybe it's because we didn't dare to tell anyone."
"Or maybe the person was dealt with before they could even give an explanation..."
Xu Changsheng nodded thoughtfully, then packed up the interrogation materials, slowly stood up and said.
"Okay, let's stop here for this time."
"For the time being, Skinny Dog, you should stay in the police station. You don't have to go back to the detention center for the time being."
"If there is anything else later, we will come to you as soon as possible."
Immediately following.
Xu Changsheng stood up, and Su Ming also stood up, ready to end the interrogation and start the next step.
Just as the two men opened the door and prepared to walk out of the interrogation room.
Skinny Dog suddenly remembered something, and quickly turned his head to look at Xu Changsheng, pulling the interrogation chair hard.
"Officer, officer."
"My daughter, my daughter, those people will surely..."
Before Skinny Dog could finish.
Xu Changsheng turned around and interrupted his subsequent words without hesitation, saying quite seriously.
"rest assured."
"Now that we know this situation, we will naturally ensure the safety of your family to the greatest extent possible."
"I will arrange for a few plainclothes officers to go there and hide nearby to wait for any suspects who may appear."
"You don't have to worry about this kind of thing."
"All you have to do now is to continue to think carefully about whether there are any other key clues or questions."
After saying that.
Xu Changsheng closed the door of the interrogation room.
Su Ming, who was walking nearby, thought seriously for a few seconds, then looked at Xu Changsheng beside him and asked.
"Brother Sheng."
"I want to conduct a cross-city search for files on the Tie San case, hoping to find some useful clues."
"Since the murderer of this falling case is from the same organization as the person who threatened Tie San as Shou Gou said, maybe the two of them have something in common."
"Even if not."
"At least we can try to uncover some of the secrets of such a large criminal organization."
Regarding Su Ming’s proposal.
Xu Changsheng naturally would not object. After all, Su Ming had discovered some very useful clues from files from twenty years ago.
Then he waved his hand to let everyone know.
"Sure. No problem."
"But we can't afford to waste time right now, so let's not go through the cumbersome procedures of transferring files across cities and provinces."
"Go directly to the Lin Bureau's office and ask him to help you get the privilege of first call and then complete the procedures. And just in time to tell him about the discovery of this large drug trafficking organization."
"What was uncovered in this case is really enough to make my scalp tingle!"
After saying that.
Xu Changsheng walked towards the direction of the Criminal Investigation Technology Department, intending to use the citizen database built by the police over the years to screen and identify possible criminal suspects in Shude Middle School.
Su Ming came to the door of the director's office.
“Knock—knock—”
He reached out and knocked gently a few times.
"Come in, the door is not locked."
Lin Tian's slightly hoarse voice sounded.
Su Ming then turned the handle, pushed the door open and walked into the director's office.
As soon as I entered.
I smelled a strong smell of cigarette smoke, and the whole office was shrouded in a thin layer of smoke.
Look towards the desk.
It was discovered that Lin Tian's right elbow was resting on the table, his forearm was suspended, and a nearly burned cigarette was sandwiched between his index and middle fingers.
Judging from the half ash of the cigarette that had not yet broken, Lin Tian probably hadn't taken a puff for several minutes.
And in the ashtray next to it...
There were at least two packs of cigarette butts in the box, but most of them had not turned yellow due to smoking.
It's obvious.
Lin Tian simply lit it...and held it.
Su Ming walked forward slowly and found that under Lin Tian's left palm was the file of the 5.13 Demon City University dismemberment case.
It must be what Xu Changsheng said earlier...
From this file, I deduced clues that had not been discovered for nearly twenty years.
That's why Lin Tian cares so much and hopes to go one step further and catch the murderer of this major case.
When Su Ming approached.
Lin Tian also put out the cigarette in his hand, pushed the file of the 5.13 dismemberment case aside, looked at Su Ming in front of him and smiled faintly.
"What's wrong, Xiao Ming?"
"Did something go wrong with the falling building case? Tell me what happened."
Su Ming sorted out his thoughts and was about to speak.
“Ding-ling-ling—ding-ling-ling——”
The cell phone on the desk rang.
Lin Tian glanced at the caller ID, then raised his hand to signal Su Ming to wait a moment, and answered the phone with a little impatience.
"Hello, Principal Qu."
"The case is still under investigation. Are you calling me again to..."
Pause for a few seconds.
As if waiting for the other party to finish speaking, Lin Tiancai continued to respond.
"Don't worry, Principal Qu."
"We will probably give you a result as soon as possible, and we understand your school's difficulties."
"In cases involving minors, the pressure from media and netizens is definitely huge."
"But there's nothing I can do..."
"We the police can't just make up a random excuse to deal with those people, right?"
"No matter how big the impact of the case is, we have to get to the bottom of it, right?"
"Alright, that's it for now."
"Stop calling me."
"I'll contact you if there's any concrete progress on the case."
"Hang up..."
