I'm a New Police Detective: Specializing in Solving Strange Cases

With the surveillance photos, wouldn’t it be enough to just check the photo information of everyone in the club?

There were only a few dozen people in total, and he and Zhang Xiaonan quickly found the woman in the photo among a pile of information.

It’s her, great, I found her.

Zhang Xiaonan almost jumped up with excitement.

The information shows that Qingqing, whose real name is Li Qian, is a 25-year-old female who is a waitress under a club contract. In fact, she is a princess, but of course the club contract cannot really include the name of a princess.

There is also a copy of the ID card with the address on it. He is not from Nanjiang, but from the neighboring city of Hucheng. The information also includes contact information. It has to be said that the personal information prepared by the current club is also very detailed.

"Captain Du, we've found it. Do we need to summon Li Qian?" Zhang Xiaonan asked Du Ming.

"You guys have decided."

A special task force was set up for this case, and the task force has the power to make decisions. In addition, Du Ming is relieved with Lin Yu's level.

Speed ​​is of the essence, so we called two auxiliary police officers and set off.

Li Qian is at work, saving a lot of time and energy.

Li Qian fits Lin Yu's psychological profile and investigation subject very well.

Moreover, there were fingerprints of Li Qian on the glass, which confirmed that Li Qian had indeed been to Xu Dajie's house that night.

So we cannot rule out the possibility that she committed the crime!

But the forensic doctor suddenly sent the latest report, saying that the cup contained sleeping pills.

However, the forensic doctor did not find any blood or sleeping pills on the fingerprints on the outer wall of the glass, so it was not enough to prove that it was Li Qian who put the sleeping pills there.

Zhang Xiaonan had a headache and had to bite the bullet and complete the interrogation.

"Li Qian, we found your fingerprints on the glass in Xu Dajie's room. How do you explain it?"

Li Qian replied calmly, "This is normal. I was in his room from about 6 to 7 o'clock. I drank from this cup, so there are fingerprints."

Lin Yu held his chin with his hand and did not speak. He was observing the changes in her expression while thinking about where to make a breakthrough.

The only evidence now is a small number of fingerprints, not even shoe prints or footprints. What should we do?

"Where have you been all night?"

"Of course I'm sleeping at home." Li Qian seemed very calm, which made Lin Yu even more suspicious.

Generally speaking, it is impossible for a 25-year-old woman to be so calm when facing police interrogation.

Only those who have practiced mentally for a long time how to respond to police questioning will appear unusually calm.

Du Ming also noticed this abnormality and thought there must be something wrong with Li Qian.

However, the surveillance footage showed that she left before 8 o'clock and had not returned, which meant that she had an alibi.

The most important thing is that Wu Li Yao saw Xu Dajie after 8 o'clock, which means that Xu Dajie could not have been killed before 8 o'clock.

Are they both lying?

Lin Yu stared at this seemingly weak woman and whispered to Zhang Xiaonan, "Let her go!"

"What, let her go? Then I have to consult Captain Du?"

"No need to ask, he will agree!"

"how do you know?"

Lin Yu showed a mysterious smile: "If you don't believe it, go ask?"

Then both parties left the interrogation room. Captain Du came out from the next room. He had been observing.

"Captain Du, Lin Yu said he wants to release Li Qian. Do you agree?"

"Let her go. There's no evidence. You can't do anything to her."

Zhang Xiaonan glanced at Lin Yu, then shouted inside: "Let her go!"

"Send someone to follow Li Qian 24 hours a day." After saying that, Du Ming put on his coat and walked out.

Then he turned around and said: "That's all for today, everyone go back and have a good rest!"

Everyone breathed a sigh of relief, finally getting off work!

Lin Yu walked out of the hall slowly, leaving Zhang Xiaonan standing there in a daze. Maybe she understood, or maybe she didn't.

Lin Yu snapped his fingers with his back to her and said, "Get off work, Miss Zhang!"

"Hey, you guys, are you just leaving like this?"

Soon, the entire office area became empty. Everyone had gone off work, and only a few police officers on duty were left in the office next door!

Fingerprints, footprints, bloodstains, Wu Li Yao, Li Qian, Xu Dajie, and Lin Yu returned to their residence and wrote them down in their notebooks, sorting out the entire case again.

What else is missing?

Are Wu Li Yao and Li Qian related?

Did she really not have the time to commit the crime?

Whose shoe print is size 42?

We have checked everything and there is no second suspicious man. Could it be that we missed someone?

He spread out all the information and investigation reports one by one, covering the entire table, and then the chairs, sofa, bed, and floor.

He glanced at the pictures one by one, and finally fell on the bed and fell into a deep sleep.

When he woke up, it was already daybreak. He opened the curtains. The morning sunlight was just right, warm but not hot.

He looked at the room full of information and smiled, thinking that the direction of his thinking yesterday must have been wrong.

If the direction of investigation of a case is wrong, a lot of time and energy will be wasted and the case may go around in circles.

So Lin Yu arrived at the detachment early and went directly to the library.

The library of the Public Security Bureau has many domestic and foreign books on criminal investigation, and can provide reference for various domestic and foreign cases.

Some books don't even have Internet access.

Sure enough, there was a similar case abroad where someone used shoes one size larger than his own to kill someone. After multiple comparisons, the police finally solved the case.

The cell phone rang, Lin Yu closed the book, it was Zhang Xiaonan looking for him.

"Lin Yu, where are we going to investigate today?" Zhang Xiaonan and Wang Qian asked as soon as they saw him.

"I know what's going on?" Lin Yu did not give a direct answer.

He came to the case handling area, wiped the blackboard clean, and wrote on it:

“Shoe print, size 42, Li Qian in disguise.

DNA, evidence from the scene, bed, clothes.”

Zhang Xiaonan read it to herself and then asked, "You mean the shoe prints were faked by Li Qian, but she can also deny that they are not her shoes!"

Wang Qian added: "Unless we can find these shoes and prove they are hers!"

"This is difficult. The murderer was able to disguise shoe prints, which shows that he has mature thinking and a high IQ, as well as certain anti-reconnaissance capabilities. How could he still have the shoes?" Lin Yu answered slowly.

What should we do then? This may be what Zhang Xiaonan wants to ask now.

Lin Yu drew another arrow, pointing to DNA.

Then he told them both, "We can't find fingerprints with blood, but we can find DNA with blood. Combined with yesterday's fingerprints and the disguised shoe prints, we don't have to worry about her not talking."

"But she still has an alibi, right? If she denies it, there's nothing we can do!"

Lin Yu sighed and sat down. The two police officers next to him were reading a police bulletin. There was a message in it that someone was defrauded of hundreds of thousands of yuan through stranger chat.

Lin Yu pricked up his ears, then slowly stood up and asked: "What did you just say? What is a stranger chat?"

"Don't you know about Mo Liao?"

Lin Yu shook his head to indicate that he had never heard of it!
