"By the way! I remembered it! It was a word that appeared on an ancient book on display in the museum last week. At that time, the archaeologist also specially introduced this word, saying that it was a newly discovered word. This word is the same as "匌" "Same pronunciation and meaning, they are both names for prostitutes!"
Professor Cui said excitedly.
prostitute? Another prostitute!
The "pintou" mentioned by the thief who intended to harm Yu Dan also means prostitute.
All three cases involved words related to "prostitute."
Han Cheng felt that this was no accident, they should be inextricably related.
But now these are just his speculations.
He needs to find more evidence to support it.
Now the suspect's DNA has been extracted from the handle of the knife dropped by the murderer in the Yu Dan case. Unfortunately, there is no DNA data of this person in the police DNA database.
So there is no way to compare!
However, this DNA data is not useless, it is important evidence.
As long as you have a suspect and compare their DNA, the suspect will naturally be the one with the greatest suspicion.
Han Cheng felt that he was getting closer and closer to the truth.
However, at this juncture, another murder occurred!
A young woman named Wan Qing was murdered at home!
It was also in an old residential building, and there was no surveillance nearby. It was also the same method of flying into the room through the window to kill, and it was also the same "Ling Chi" torture and murder of the victim.
Obviously, this murderer is the same murderer as the previous two murders.
This time the murderer was even more arrogant. He actually used the deceased's mobile phone and the deceased's voice used the timer function to make a call to the police.
By the time the second criminal investigation team arrived at the scene, the murderer had already disappeared.
Three murders occurred in succession. In order to remind the citizens of Nan City to be more vigilant and take preventive measures, the police had to announce the circumstances of several recent murders.
However, after the announcement came out, the whole city of Nan City was in a state of shock, and the citizens panicked, especially the single young women who could not sleep well at night, for fear that the perverted killer would break into the house and kill!
Seeing that the people of Nan City were panic-stricken, the leaders above issued a death order to the people of the Second Criminal Investigation Team, giving them a deadline of three days to catch the murderer and bring peace to Nan City!
Criminal Investigation Team 2 conference room.
Everyone is listening to the playback of Wanqing’s alarm recording.
"Police... Comrade, my name is Wan Qing... The murderer asked me to tell you, don't waste your efforts to find out who the snitch is. He does not belong to the snitch circle. If you want to catch him, wait for the next life... .After hearing this call, please go to Room 602, Building 7, Haitong Community, Xining Road... to rescue me..."
Wan Qing's voice was mixed with pain and fear.
Han Cheng speculated that this recording should have been forced by the murderer when he was "Ling Chi" to Wan Qing.
After listening to the recording playback, everyone fell into silence, and their mood sank to the bottom.
This murderer is so arrogant!
"Who among you went to the outside without permission to investigate the snitch and alert the enemy?"
Luo Lin is now one of the top two. Three murder cases occurred one after another. The superiors gave him a death order. If the case is not solved within three days, he will be demoted to a regular police officer.
He originally thought that since Mr. Li was away, it would be a good opportunity for him to make a meritorious service, but in the end he failed to make a meritorious service, and he might not be able to be a criminal policeman in the future!
"Captain Luo! It's my fault, I'll take the responsibility! I thought I would get more information by asking the snitches with criminal records outside!"
Chi Shen blamed himself.
He now finally realizes that self-righteousness can really kill people!
"This is a human life! Can you bear this responsibility? It was because your unauthorized actions offended the murderer that he committed another crime so quickly!" Luo Lin shouted.
"Captain Luo, now is not the time to hold people accountable. The top priority is to focus on finding the murderer!"
Seeing that the atmosphere was not good, Han Cheng came out to smooth things over.
Chi Shen did not expect that Han Cheng would come to his rescue regardless of his past grudges, and cast a grateful look at Han Cheng.
"Han Cheng, what do you think we should do now?"
Luo Lin felt that what Han Cheng said made sense, and now that it was urgent, there was really no point in holding anyone responsible.
Han Cheng pondered for a while, "Now I am 90% sure that the Yu Dan case should be the first case committed by the murderer. According to the knife he left at the scene, I have had his DNA extracted. As long as Let’s compare the DNA of snitches with and without criminal records in Nan City, and I believe we should gain something!”
"I always think the murderer should be a snitch. From a psychological point of view, the more a person denies others' suspicion of him, the more guilty he is!"
"Your analysis makes sense!" Luo Lin nodded and then gave the order, "From now on, each of you will bring a group of police officers to compare the DNA of all the snitches in Nan City. No one can be left behind!"
"yes!"
After that, everyone dispersed in a hurry.
In order to solve this serial murder case.
After two days of overall busy work at the Jiangnan Branch.
Everyone compared the DNA of all the snitches in Nan City who had criminal records but did not, but none of them successfully matched.
This time it was Han Cheng's turn to be confused.
Was my judgment wrong? The murderer was not a snitch.
From his skillful technique of flying into a house through windows and the clues left behind by Yu Dan's case, Wan Qing's recording...
All kinds of evidence show that this murderer is definitely an expert in breaking into houses through windows.
Could it be...
Han Cheng suddenly had a flash of inspiration and became excited.
He finally knew what he was missing!
There is no doubt that the murderer is a snitch, but he may not be a snitch from Nanshi. He may be a snitch from other places who came to Nanshi to commit crimes.
If this snitch fled Nanshi every time he committed a crime, they would not leave any information about him when they visited.
That's why he dared to use Wan Qing's mouth to say wildly that the police would never catch him!
However, the devil is as high as the Taoism!
Even if he is a thief who has fled to Nanshi to commit crimes, Han Cheng is confident that he will be caught!
Because Han Cheng just obtained the double-speed viewing skill.
As long as he sifts through the people who left Nanshi shortly after the four cases were committed and finds the same person, he will most likely be the murderer.
Because the probability of a person leaving just after four cases happened is really low!
In order to be more sure, Han Cheng not only checked the surveillance videos of Nanshi's bus stations, train stations, and highway intersections in the past month, but also checked the museum's surveillance videos.
Because Han Cheng believed that the murderer probably learned that special word after reading the ancient book on display.
It can be seen from this that the murderer should still be a thief who likes to show off his elegance.
But no matter how elegant he is, he can't change his cruel nature.
