At eight o'clock in the evening, in a café on the side of the street.

"Mr. Li, I hope your opinion on this case is rational and helpful for us to solve the case, otherwise I don't think there is any need for me to waste time with you here."

Li Chenfeng hurriedly nodded and smiled: "Of course, in fact, what I told you during the day is just one of my many conjectures, since Officer Liu doesn't believe in strange forces, I won't mention it."

I think that this series of serial murders may be vendettas, and no clues can be left at the crime scene, or the clues left are not enough for the police to detect, that is to say, the suspect must have made a very careful plan before the killing, plus the victim's home did not have any property lost, and the victims were both male and female, so it can basically be ruled out that it was motivated or murdered for money. ”

Li Chenfeng knew in his heart that for a complete materialist believer, it was impossible for him to believe in the existence of ghosts in this world no matter what, so Li Chenfeng did not plan to work in vain in this regard.

But after all, this matter has to be dealt with, so he plans to follow Officer Liu's intentions first, so that he can inadvertently pay attention to the clues he provides, so that he can at least intervene in this case, and can also guide Officer Liu invisibly.

As for the final truth, as long as the matter is clarified first, and then he adds fuel and vinegar to say that it is really an ordinary vendetta, Officer Liu has no reason not to believe it anymore.

Officer Liu nodded after hearing this. "Mr. Li, your analysis is very reasonable, but we made conjectures in this regard a long time ago, and we also conducted a series of investigations, but in the end, we found that all the victims basically had no enemies."

Li Chenfeng smiled slightly and said, "It's not that he didn't hide too deeply, and you haven't found out yet." If you think about it, one person has a feud with a dozen people at the same time, and it is enough to cause a murder, what an obvious clue this is. ”

"Mr. Li, what do you mean?"

"Half a year ago, there was a tragic case of a girl jumping off a building to commit suicide in Changjin Building, and I suspect that it is related to the current serial murder case."

As soon as he heard this, Officer Liu's face suddenly changed, and he said, "That girl is dead, you don't want to say that the suspect is that girl." ”

Li Chenfeng shook his head and said, "Of course not, although the girl is dead, what about his relatives and friends?" I think you should have heard about the fact that the girl launched a vote on the Internet before she committed suicide, Officer Liu, if the deceased in the back were all people who participated in the vote at that time and voted for support, this must be a great blow to the girl's relatives, and it is very likely that he will hate these people later. ”

At this time, Officer Liu suddenly fell into deep thought, and said after a long time: "If the deceased were all netizens who participated in the voting at that time, your conjecture is indeed very possible, but the problem now is that we can't be sure whether the deceased are those netizens." ”

"I really don't know, but isn't this exactly what you should investigate now, in fact, what I just told you is not a clue, just to provide you with a reconnaissance direction, otherwise you are now busy like a fly without a head, and in the end you still can't get any results."

Finally, Officer Liu nodded. "That's right, it does make a lot of sense, Mr. Li, thank you very much for your support of our reconnaissance work."

Li Chenfeng breathed a sigh of relief, this guy finally listened.

"You're welcome, I just hope to be able to help you deal with this case together, and I hope you can agree."

Officer Liu hesitated for a moment and said, "Very welcome, I plan to go to the Changjin Mansion tomorrow to investigate, and you can also come over when the time comes." ”

Li Chenfeng smiled and nodded. "It's an honor."

After returning to the bookstore, Li Chenfeng collected a lot of information about the girl named Wu Qian on the Internet, and analyzed it deeply, and didn't sleep until two o'clock in the morning.

Luo Wei complained while lying on the bed: "Boss, can you turn off the computer, I can't sleep at all." ”

"Don't panic, don't panic, it'll be fine right away."

"Oh, who the hell is that Officer Liu, you are so concerned about his affairs, you shouldn't be interesting to others, right?"

"What kind of international jokes, Lao Tzu is a straight man of steel, and it has nothing to do with him."

"Then why are you helping him?"

"Just because I want to help, there's no other reason."

Luo Wei looked speechless, reached for the remote control on the bedside table to turn down the air conditioner, and then covered her whole head under the quilt.

For Officer Liu, Li Chenfeng does have a special affection for him, of course, it can't be like Luo Wei said.

First of all, Li Chenfeng felt that Officer Liu was very upright and could be regarded as a really good policeman, and secondly, because Li Chenfeng grew up in an orphanage and was taken care of by many public officials during this period, he had a grateful attitude towards public officials, which led to his series of actions.

The next morning, according to the time agreed with Officer Liu, Li Chenfeng went to the Changjin Building, and Officer Liu was followed to investigate by two young people who had just graduated from the police academy, a Xiao Zhang and a Xiao Wang.

Xiao Zhang wears big black-framed glasses, is very tall, but his body is very thin, he doesn't look like a real criminal policeman who can really do it, thinking that he should be an intellectual in criminal investigation.

Xiao Wang looks strong and strong, and the whole person is more cautious, just like the appearance of an ordinary policeman.

After the four of them walked into this building, they found that the interior of this building, which is located in the most prosperous area of the city center, actually looked a little bleak and dilapidated.

There was no one in the security room on the first floor, and even the elevator had no electricity, so the four of them had no choice but to take the stairs to the thirteenth floor where Wu Qian originally lived.

As soon as he walked to the staircase, a rickety old man suddenly walked down from upstairs, and when he saw Officer Liu and they were wearing police uniforms, he suddenly stopped in front of them.

"Comrade policeman, what are you doing here?"

Officer Liu said to him politely, "We are going to No. 4 on the thirteenth floor to investigate some things." ”

As soon as he heard this, the old man's face suddenly changed, and he said: "Comrade policeman, that girl on the fourth floor on the thirteenth floor committed suicide by jumping off the building half a year ago. ”

"Uncle, we know this, we are here to investigate this case again, do you know that there are still people in her family?"

The old man shook his head. "No, no, that girl is an orphan, and she rented the house."

At this time, Officer Liu suddenly turned around and looked at Li Chenfeng, who smiled a little embarrassedly, not knowing what to say.

Then he continued to say to the old man: "Then old man, do you know where the person in charge of the key to this building is, we want to go into Wu Qian's house to have a look." ”

The old man said, "I am the one who takes care of the key, and you come with me." ”

The four of them followed the old man and walked, and Xiao Zhang suddenly said: "Such a good building, why does it look like no one lives in it, and why doesn't the elevator provide power to such a high floor?" ”
