"Brother Meng, this is Li Chu."
...
"What's the status of that case you told me about on Wenxuan's wedding day?"
...
"Has it been reported to the procuratorate and is it awaiting prosecution?"
...
"There's still time. Here's the thing, do you have time now? If you do, come to my place. I have an idea that might help us figure out whether it was the person you arrested who committed the crime."
...
"Okay, I'll wait for you."
Li Chu let out a sigh of relief after hanging up the phone.
If this case can be solved through DNA analysis, then Meng Ge and his team will have something to brag about.
This is absolutely a landmark event in the history of criminal investigation.
Zhang Meng arrived even faster than he had expected, running into his office breathless.
"Xiao Chu, do you have any way to find out if it was that person who did it?"
"Don't rush, Meng Ge, I can't run away. Sit down and have some water, and I'll tell you slowly."
"Stop talking slowly, hurry up and tell me, I'm in a hurry."
"Okay, didn't you say last time you got some blood from the suspect, and that it matched the blood type of the person you arrested?"
"yes."
"The bloodstains are still there, aren't they?"
"Of course, that's evidence."
"Bring that bloodstain over here, and then draw a tube of blood from the person you captured. Take it to our lab here to do a DNA test, and you'll know if it's the same person by comparing the results."
"Deceiving Emperor Kangxi"
? ? ?
"What A?" Zhang Meng looked at Li Chu with a face full of question marks.
"I can't explain it to you clearly in a short time, just think of it as a blood test to determine kinship."
This time, Zhang Meng's head wasn't filled with question marks, but rather with black lines. If he weren't worried about not being able to beat Li Chu, he would have wanted to slap Li Chu right now.
"Can't you be a little more reliable? Are you trying to fool me because I'm uneducated or something? Everyone knows that blood test for kinship is fake."
"Haha..." Li Chu laughed at himself.
"That's right, the thing I'm talking about is called DNA. You can think of it this way: everyone has it in their body, and it's unique. That means even twins can't have exactly the same DNA."
This substance can be extracted from blood or hair. Go back and ask your department's forensic doctors or lab technicians; they should have encountered this when they came to the base for training.
"You mean, the people from our bureau who were sent there for training last time all know about this?"
"Yeah, you should know that."
"Then why didn't they say anything this time?"
"Because this technology doesn't seem to have been used in solving cases yet."
"So how did you come up with that idea?"
"Brother Meng, you've got a lot of questions. I came up with a solution for you, so why are you interrogating me now?"
"Oh no, no," Zhang Meng quickly waved his hand, "I'm just a little curious. Is this kind of technology you're talking about reliable?"
"That depends on the skill level of the DNA testing personnel. However, the young men from our hospital have been studying there the longest, so I think they should be about the same."
Zhang Meng sat there and pondered for a while before nodding heavily: "Okay, I'll go back and ask our bureau's forensic doctors now. If it's feasible, I'll arrange for someone to come find you right away. Please help us by telling the lab."
"That's no problem, but let me make it clear first, it costs money to do this."
Zhang Meng stared wide-eyed at Li Chu: "You want money for this?"
"What do you think? Those kinds of equipment aren't available in China, and they cost a lot of money each time you use them."
"Can't you do it for free?"
"Brother, please don't joke around. We're using military funds for this. If we give it to you for free, how are you going to get reimbursed by the lab?"
"Phew~ How much does it cost per session?"
"I don't know the exact amount, but it's definitely in the hundreds."
"How much? Why don't you just rob me?" Zhang Meng almost jumped up.
"Don't get excited. The price I mentioned is already discounted. Those consumables and such need to be purchased with foreign exchange."
"If there are so many, then I need to apply to the bureau."
"Seriously? You, the deputy director in charge of criminal investigation, don't even have this much financial power?"
"Don't you know that these days, the bureau chief has all the power?"
"Brother Meng, let me give you a heads-up: Uncle Wang is planning to retire next year."
Li Chu's sudden turn of events almost caught Zhang Meng off guard, and it took him a while to realize the meaning of his words.
Looking at the meaningful smile on the person opposite him, Zhang Meng nodded thoughtfully.
"Got it, bro, thanks!"
“No need to be polite, brothers. Let me give you another piece of advice: you’d better get out of the public security system.”
This time, Zhang Meng nodded without hesitation, without even needing to ask why.
He knew that given his relationship with Li Chu, which he had known since Nanniwan, there must be a reason why Li Chu could say such a serious thing.
Li Chu breathed a sigh of relief. It would definitely be no problem for Uncle Wang to promote Zhang Meng one more step before he stepped down, but if he promoted him in the same place, that would be a big problem.
Don't forget, it's only been five years since that incident.
If Zhang Meng were to sit in that position, he would definitely be a scapegoat.
That incident affected a lot of people. Since we know it will happen, those of us who are on the same side should try to avoid it.
Jia Dong and his wife don't need to be moved; their rank is too low.
Before leaving, Zhang Meng, still unwilling to give up, asked one more time: "Is the price really no lower than that?"
"Here it is. After your person arrives, I'll take him to the lab, and your person can negotiate the price with Director Sun themselves, how about that?"
"Forget it, you talk to us instead."
Zhang Meng wasn't stupid. If they went to negotiate, they could probably get it for over a thousand. No matter what it was, as long as it involved foreign exchange, it wouldn't be cheap.
Li Chu shook his head and chuckled as he watched Zhang Meng hurriedly leave his office. He picked up the mug on the table, took a sip of water, and then prepared to go to the outpatient clinic for another look.
"Boss, there's a man named Zhu Wen downstairs looking for you." Zhao Zhijun appeared at the office door as if he had timed it perfectly.
"Zhu Wen? Bring him up here."
"You don't actually want to do the work on our new outpatient and inpatient buildings, do you?" Li Chu joked, looking at Zhu Wen who followed Zhao Zhijun in.
"Brother Li, that won't do. I know my own limitations. I can't do that kind of work."
Zhao Zhijun poured a glass of water for Zhu Wen, who had already sat down. He had to remember someone who could make the leader joke.
"Tell me, what brings you here?"
"Hey, Brother Li, it's like this, could you please talk to Boss Xu and let me do the restaurant renovation job?"
"Boss Xu? Oh, you mean Xu Damao, right?"
"Yes, yes, that's him."
"What? The news spread so fast?"
