"Xu Tian." Lao Chen called Xu Tian to the mouth of the alley.

"Are you going to argue with me?" Xu Tian said.

"I'm not talking to you about the last incident, I know very well that even if I say it in my throat, you won't change your mind, people like you have their own ideas."

"Then let's discuss this case!"

"No, I called here because I wanted to avoid other police officers, you already know about Mr. Jin, I discussed it with Li Zhitong repeatedly, and finally we decided to investigate Mr. Jin's life experience, I wanted to ask your opinion."

"Of course, Mr. Jin's life history must be investigated, I don't believe that there can be people in the world who look exactly the same except for twins, but Mr. Jin said his life experience, I don't think Mr. Jin was hiding his past at that time."

"Your analysis is very correct, the police have actually verified this a long time ago, Mr. Jin is an undercover policeman, and his top boss has already verified his life experience, and the result is the same as you know, Mr. Jin is indeed confirmed to have no twin brothers."

"It's not easy to investigate and collect evidence, right? I've heard Mr. Jin say that his biological parents are no longer alive, and it is impossible to find the DNA samples of Mr. Jin's parents now, right? ”

"This matter is really difficult to investigate, and there are many doubts and loopholes, such as the doctor who delivered the baby when Mr. Jin was born, so long has passed since the 80s of the last century, but that person still remembers the events of that year, which makes me feel very suspicious."

"That's right, obstetricians and gynecologists have to deliver a lot of babies in a year, although the one-child policy has been implemented in the eighties of the last century, but there were many superbirths in the family at that time, and there were more children born in that era than now, if it is not for special circumstances, the doctor who delivered the baby should not remember it so clearly."

"Li Zhitong has already gone to investigate this matter, but I think things may not be so optimistic, whether it is Mr. Jin himself or the police, the information in their hands is the same, I think this time Li Zhitong should also return in vain."

"And what's the point of you talking to me?"

"I think you should send Sitong away, now that we are very close to Zhinian Tai Sui, this juncture is very dangerous, if Sitong continues to stay here, I am afraid that something will happen."

"Are you worried that the ruling Tai Sui will use Si Tong to threaten me?"

"I'm just giving you a warning, but I'd like you to listen to my advice."

"Where do you think I can send Sitong? Village? A few months ago, Sitong's adoptive mother committed a number of murders in the village, do you think Sitong can be treated well by the villagers when she goes back? ”

"You're right, the two sisters, Sitong and Siyan, are now considered homeless children."

"Don't discuss this matter, I know your kindness, now let's discuss today's case!"

"I don't have any eyebrows, do you have an opinion?"

"Now you go and investigate the reason why no one showed up in the vicinity last night, I don't think this incident should be manipulated, there must have been something last night that prevented pedestrians from coming here, and it's important to investigate."

"I understand what you mean, the murderer must have known in advance that no one would come to this area last night, and if the reason is found, the murderer can be found."

"I hope so! But I'm still very concerned about that back door, do you remember the scene when you arrived at the scene of the crime in the morning? ”

"Of course I remember that it was a helper who found Yan An's body, and the restaurant owner picked up all the clerks in the morning, but it was different from the night, during the day, everyone entered through the front door, and the first person to enter the kitchen at that time was the helper, and then everyone came in, and the helper who found the body didn't have time to commit the crime."

"Was the back door open or closed when the body was found?"

"According to everyone's confessions, the back door was open at that time."

"Open?"

"Yes, it's not open, it's not closed, it's just a little bit open, it's the kind of state that is gently covered, but not completely closed."

"Are there any traces of wiping on the doorknobs and the inside and outside of the door?"

"No, there are a lot of fingerprints superimposed on it, and after we compare them one by one, we find that they are all the fingerprints of the clerk."

"Are there any fingerprints of the deceased?"

"This is also the most suspicious, no fingerprints of the deceased were found on the back door, but there are fingerprints of the deceased everywhere in the kitchen."

"What position did the deceased work in?"

"It's the waiter in front, who is responsible for ordering and serving food. The fingerprints of the deceased that we have detected are a bit strange, and many fingerprints of the deceased were found on the lower part of the kitchen cabinet and on the table leg, and the deceased would not have touched these locations under normal circumstances. ”

"Have these fingerprints been rubbed?"

"No, the fingerprint sample is very complete, it should have been glued recently, and the appraiser can be sure that these fingerprints were glued within 24 hours."

"That means the deceased may have been in the kitchen last night, and the deceased may have been squatting, sitting or lying on his stomach."

"I thought so, too, the deceased must have leaned down and done something last night."

"Didn't you detect fingerprints other than the clerk in the lower part of the kitchen?"

"No, the fingerprints of the clerk were not detected at the low place, so it can be said that there are only the fingerprints of the deceased at the low place."

"What does that mean?" Xu Tian dragged his arm into thought.

Xu Tian flipped through the photos of the crime scene again, the deceased's clothes were very strange, the police had confirmed that the women's clothes were worn by the deceased himself, so what could he do in the kitchen by leaning over?

Xu Tian simulated the scene in his mind, when the deceased Yan An should be struggling on the floor of the kitchen, because there was danger approaching at this time? No, the appraiser said that the fingerprints were very complete, which means that Yan An was not in danger when he left his fingerprints, and he deliberately grabbed the table leg.

Being able to do this kind of action can only be associated with one thing, Yan An was doing indecent things in the kitchen at that time.

But how did Yan An get in? Stole the chef's key and secretly got one? This is not the key, the most critical question is who came to the hotel first last night, Yan An or the murderer? It's the question that's the most critical.

Just thinking about it, Li Ming suddenly ran to the mouth of the alley.

"Team leader, no!" Li Ming shouted out of breath.

"What's going on?" Lao Chen shouted.

"Your phone can't get through, the police station called me, and a similar murder happened in a residential building."
