Zhou Xingxing in Zhong Xin's office said: "Zhong sir, we have already checked, on the night Lu Wanmei was killed, Wu Qi was detained by our colleagues from the police station next door for drag racing until dawn, so our only suspect clue has been cut off." ”

Zhong Xin replied: "Don't be discouraged, continue to follow up on the case, I will go to Chief Song to report the situation, and you will continue to investigate." ”

The police station received a report that "a woman's body was found on the roof of Lanwan Garden," and the 4th team of Cao Dahua's serious crime team immediately set off to the scene.

The scene was cordoned, Cao Dahua followed the team to the scene, and the colleagues who collected evidence at the scene saw Cao Dahua and said: "Chief Cao, the victim is a woman, suspected to be a Jian homicide, and there are obvious strangulation marks on her neck." ”

Cao Dahua glanced at the victim and said, "Sir Gao, when will you be able to issue a report on the collection of evidence?" Gao Yanbo replied: "We will give it to you as soon as possible, before noon, and you can go to Gu Sir if the autopsy report is issued." ”

"OK, no problem, pay attention to the report with Gao sir later."

Fan Jiao immediately replied: "It's Chief Cao." ”

...

In Song Jiaming's office, Zhong Xin and Cao Dahua sat in front of him respectively, and Song Jiaming spoke: "There have been two similar Jian murder cases, and the modus operandi is very similar, I plan to set up a task force, who will take over the two of you?" ”

Zhong Xin looked at Cao Dahua and said, "Sir Cao, are you coming or am I coming?" ”

Cao Dahua replied: "Then you come, I don't have enough manpower here, if you need my help, remember to tell me." ”

"Okay, Chief Song, I'll take over."

Song Jiaming replied: "Okay, Zhong Sir will leave this matter to you, I want to hear your analysis of the two cases now, Da Ge, if you have nothing to do, you can go back to the office first." ”

After Cao Dahua went out, Zhong Xin spoke: "Sir, the two victims are both young women, and they were both killed at the place of accommodation, saying that this person is familiar with their home addresses, but they don't know each other, and I can't think of anyone who can connect them." ”

Song Jiaming replied: "That's right, solving the case is to make bold guesses and carefully verify them, and by now you should have discovered their common characteristics." ”

"It's possible that the murderer was committed by an acquaintance, but judging from all the interpersonal relationships, there is no connection between them at all, so have you seen Lin Guoyun's case?"

Zhong Xin looked at Song Jiaming and replied, "Chief Song, you mean that they must have known someone at the same time, or had consumed together somewhere, but how did the murderer know their addresses?" ”

"Ashin, where do we usually go to spend or what are we doing, so that we can safely tell others our address, and we are not afraid of this kind of behavior?"

Zhong Xin said in a flash of inspiration: "When we come to the police station, we need to leave a detailed address, we need a detailed address to deposit money in the bank, we need to fill in the detailed address when we go to the hospital to see a doctor, and we also need to fill in the detailed address when we go to the shopping mall to ask others to deliver to the door, etc., some can't count the sir." ”

Song Jiaming replied with a smile: "I can't think of it, don't think about it now, take me to see their bodies, as well as their crime scene, I want to find out what the murderer's motive is." ”

"Ah, sir, seriously, what did you study in college?"

"Me, LL.M., what's the problem?"

"No wonder you are the inspector as soon as you come in, I will obey you for this."

"Oh, I forgot to mention, I still have a master's degree in economics, and a bachelor's degree in psychology, management, and computer technology, do you have any questions?"

Zhong Xin stood up straight and couldn't walk, and asked in surprise: "Are you old and old?" ”

Song Jiaming raised his head and thought for a while and said sadly: "This year's age is 23, the virtual age is 24, and he is about to enter 25, and Huang Huang is going to 26 again. ”

....

Song Jiaming and Zhong Xin came to the office of the forensic doctor Gu Zechen, and Gu Zechen asked: "Chief Song, what is the big thing that bothers you to go out in person?" ”

Song Jiaming replied: "It's not two Jian murders in a row, I decided to come over and see the details, see if there is anything I missed, please ask Doctor Gu to tell me what is the connection between the two when you solve the anatomy." ”

Gu Zechen thought for a while and replied: "This seems to be nothing, except that they were all pinched and killed, I didn't think of anything, ah... But there's one thing I don't know if I can give you some inspiration. ”

"I found out that the same perfume is used between the two, and I originally thought that it is normal to use perfume now, but if you say that, I can only think of such a common feature."

"Very good, Doctor Gu, now can you let me smell this scent?"

"No problem, there are still some clothes left on their bodies, if you can't do it, I'll go to the perfume shop with you."

"Okay, thanks."

...

Gu Zechen said to the salesperson: "Please spray this bottle of perfume again." When the salesman sprayed perfume again, Gu Zechen said to Song Jiaming: "Sir Song, that's the smell of this perfume." ”

Song Jiaming took the bottle and looked at it, the brand name was envy, and then he sprayed it out and smelled it again, saying: "This smell is a little special, and it is rare to see people on the market use this perfume smell." ”

Gu Zechen replied: "Do you think the murderer will be sensitive to this fragrance, and then kill people in a rage?" ”

Song Jiaming thought for a moment and replied: "There is a possibility, the murderer thinks that the woman who uses this perfume is the si, or his family factors, when he smells this smell, he will want to kill this kind of person, and he will also give the person to Jian." ”

"Okay, thank you, Doctor Gu, I'm really bothering you today, and after the case is solved, I'll treat you to dinner."

"OK, no problem."

In Song Jiaming's office, Zhong Xin took the two victims' various bank card consumption bills, and in these data, it was found that the two victims had spent money at a medical center called St. Peter's, and he immediately came to report the news to Song Jiaming.

Song Jiaming opened his mouth and said: "Medical center, this is also in line with our inference, you also have to write out the detailed address here, but there are doctors and people in the archives who can contact this detailed address." ”

"In this way, Ashin, tomorrow you can arrange for someone to go to this hospital to have a look, and let the girls in your group spray this perfume to see a doctor, and try all the doctors who have treated two victims at the same time in this medical center, as long as there is no alibi, all of them must be seen, and we must protect the safety of our team members."
