Let You Catch The Thief, You Broke The Serial Murder Case?

After Lin Nan and the other three returned to the criminal investigation team, they found that the criminal investigation team was carrying out various tasks in an orderly manner.

The clues and information about Landie's dictation were also confirmed by them one by one, and they also extended from it, and found more useful information clues.

For a while, the three of Lin Nan did not have any new tasks and jobs, and seemed to have nothing to do. They just had to wait.

Lin Nan read all the latest information, went through it in his mind, and constantly adjusted the plan.

Before I knew it, it was time to leave work. Before leaving, Lin Nan and Li Yanran said:

"Dead girl, be careful recently, if there is a stranger approaching, you must pay attention, this person is very likely to have bad intentions, especially women!"

"Why!" Li Yanran asked directly, "What's wrong with me?"

"That Lan Xiner is very likely to set you as the next target." Lin Nan touched his chin and said, "Then, pretend to be you and go to the police station to destroy her evidence!"

"Anyway, be careful recently!"

"Huh? Pretending to be me?" Li Yanran pointed at herself. "Then let her come, I just want to fix this guy with a human face and a beast heart!"

"Still pay more attention, the other party may use a sinister trick!" Lin Nan smacked his tongue: "Once you intuitively find that there is a problem, you can just do it directly. By the way, do it gently, don't kill anyone!"

"Don't worry!" Li Yanran clenched her fists and said confidently, "I'm measured!"

"I suddenly thought of a question." Xiong Zhuangshi on the side asked puzzled: "Why do you feel that you are so eager to lead her out?"

"Let's wait for the two sisters, Tan Xiaotong and Tan Xiaoxiao, to find out Lan Xiner's fingerprints, so we can just arrest her directly!"

"Why so troublesome?"

"Brother Xiong, practice less barbells and learn more!" Lin Nan explained helplessly: "Fingerprints are actually when a person's finger comes into contact with the surface of an object."

"Because the fingers have uneven lines, the marks formed by the secretions, sweat glands, dust and stains attached to the finger or the surface of the object are separated by the lines, just like a stamp."

"The collection of fingerprints is a very delicate work, and the fingerprints that are wiped off also depend on the degree of erasure."

"If the characteristic part is destroyed, then the collected fingerprints are also meaningless."

"Fingerprints are divided into latent fingerprints and formed fingerprints."

"If it is latent fingerprints, there is no exact time of disappearance."

"Fingerprints in the dining room can last for days, indoors for weeks."

"Fingerprints on mirrors, dressers, and safes can be kept for more than a month."

"Fingerprints on paper can be chemically revealed years later."

"If it's a formed fingerprint or an obvious pattern, it's not equivalent."

"The residue of fingerprints can be guaranteed for at least a week or more."

"So, what do you think is the chance that Lan Xiner's complete fingerprint can be extracted from the evidence in the room that has been left for three years, burned by fire, and sprayed by a dry powder fire extinguisher?"

"Ah this... After talking a lot of nonsense, just tell me that I can't extract it!" Xiong Zhuangshi scratched his head and said, "I feel like you are despising my professionalism after going around such a big circle."

"Since it can't be extracted, why did you let the two sisters Tan Xiaotong and Tan Xiaoxiao spend so much time?"

"It doesn't mean that it can't be extracted, but the probability is infinitely close to 0." Lin Nan said: "But there is still a chance to extract a complete fingerprint."

"As long as there is no chance of 0, we have to try, isn't that our working principle?"

"Tan Xiaotong and Tan Xiaoxiao also know this."

"That's why they would go to great lengths to test all the items in the room for evidence."

"Otherwise, do you think they wouldn't know this?"

"Thank you so much for your compliment!" Tan Xiaotong stood behind Lin Nan like a ghost, and said angrily:

"The miracle didn't happen."

"Xiaoxiao and I kept checking all the evidence in the room overnight, but we failed to extract Lan Xiner's fingerprints!"

"You need to find new clues!"

Lin Nan was startled and looked back.

good guy!

These two big dark circles.

It can be seen that Tan Damei has been a little busy with her work recently.

"Okay! The bad news has been told to you!" Tan Xiaotong turned to leave with a breath, and said, "I'm going back to have a good rest."

"Okay! Now that there are no fingerprints, there is no other evidence. She doesn't need to destroy the fingerprint evidence. Is it still useful for you to dispatch the snake?" Xiong Zhuangshi shrugged.

"We don't have fingerprint evidence, but it doesn't prevent her from thinking we have her fingerprint evidence!" Lin Nan smiled slightly.

"As long as she thinks we have fingerprint evidence, she will definitely come!"

"And then!" Xiong Zhuangshi nodded and continued to ask: "Even if Lan Xiner is brought in and caught, what can you do with her?"

"We don't have the slightest evidence in our hands that she killed someone!"

"Unauthorized detention and interrogation violates principles and rules and regulations."

"Not bad!" Lin Nan nodded without questioning and said, "We have no evidence, so we can't imprison her on suspicion of murder!"

"However, we can check her ID first, and then detain her for interrogation!"

"Check the ID card?" Xiong Zhuangshi was a little stunned and stunned.

"Have you forgotten?" Lin Nan said with a sneer, "As a police officer, we have the right to ask her to show her ID card for inspection to ensure public safety."

"If she doesn't cooperate, it's a crime of obstructing official duties!"

"If she cooperates."

"Hehe~"

"What does she cooperate with?"

"A person who doesn't even have his own ID."

"The falsified identity information was also sufficient to bring her back for interrogation."

"These must not violate the principles and rules and regulations!"

"Ah... this is attention! It's really amazing!" Xiong Zhuangzhuang scratched his head and said with a thumbs up:

"I admire you!"*
