"Hey! O Angkor! I didn't get off work! ”

Wu Yu said: "Go forward." How can we get off work so quickly! I haven't been in the bureau all the time. What are you looking for me? ”

"Brother Yu, when you came to my detective agency today, I actually forgot to ask the most critical thing."

Wu Yu said: "What." ”

"Brother Yu, it is the evidence at the scene of Meng Nan and Jin Shilei's bodies. I don't know at all. ”

Wu Yu said: "Ah! That's what you're asking. ”

"That's right. Brother Yu, it's convenient for you to talk to me now! ”

Wu Yu said: "Convenient, what's inconvenient." Meng Nan died in the grass 600 meters at the south gate of Changchun Park, and when the forensic evidence was collected, there were blood stains left within five meters of Meng Nan's body, and although there were some stones next to Meng Nan's body, they were not the stones that killed Meng Nan. ”

"In that case, the murderer took the murder weapon."

Wu Yu said: "There are factors in this regard! In the information given to the police by forensic medicine and forensics, Changchun Park is Meng Nan's death at the first scene, and the body should not have been killed by the murderer before moving to Changchun Park. ”

"Brother Yu, aren't there any footprints around the grass?"

Wu Yu said: "There are often people walking on the grass. There are definitely footprints, and the forensic evidence in the pictures of the footprints collected has the imprints of tourist shoes and high-heeled shoes. Finding directions to footprints is like looking for a needle in a haystack. Therefore, it is almost small to find the murderer on the footprints. ”

"Oh yes. After all, it's a park, and it's normal for people to walk on the grass. Anything else? ”

Wu Yu said: "Forensic evidence picked up a few cigarette butts forty meters away from Meng Nan's body, and forensic evidence confirmed that those cigarette butts may have been discarded before and after the crime. There are visible lipstick marks on the cigarette butt. But we police are not sure if it has anything to do with this case. ”

"Oh! Is that all there is to Brother Yu? ”

Wu Yu said: "There is so much evidence in Meng Nan's case now. ”

"Brother Yu, where is Jin Shilei."

Wu Yu sighed and said, "Jin Shilei's is more troublesome!" ”

"What's the trouble?"

Wu Yu said: "When we found Jin Shilei's body, Jin Shilei foamed at the mouth. The forensic doctor did not find any injuries on Jin Shilei's body, but when the forensic doctor dissected Jin Shilei, he found that Jin Shilei died of potassium cyanide. ”

"Potassium cyanide ......"

I didn't know much about chemistry in school, I didn't know what potassium cyanide was, but I knew in my heart what poison it must be.

Wu Yu knew that I might not understand chemistry, so he quickly explained: "Potassium cyanide is commonly known as mountain worm poison. If you take it, you will definitely die on the spot. ”

"Oh! It seems that this murderer is much more cautious than Meng Nan in killing Jin Shilei. ”

Wu Yu said: "It's not just cautious. The forensic forensic team did not collect any valid evidence in the vicinity of Jin Shilei. So I'm now speculating that the train station wasn't the first scene of the crime. ”

"It stands to reason that the train station is full of people all year round, and Jin Shilei will definitely have eyewitnesses at the train station."

Wu Yu said: "Our police have investigated. It was indeed found that an employee of a hotel saw the deceased Jin Shilei while he was working. ”

"What the witness said."

Wu Yu said: "The witness said that he saw Jin Shilei walking into the alley alone. ”

"That witness is sure that Jin Shilei walked into the alley alone! No one else. ”

Wu Yu said: "Our police questioned several times, and the witness confirmed that it was Jin Shilei who walked into the alley alone. ”

"That's weird. So how did the murderer poison him? Could it be the airborne mountain poison? ”

Wu Yu said: "This is also my headache. I've never been able to figure it out. ”

"Brother Yu doesn't have anything else?"

Wu Yu said: "Not for the time being. However, our colleagues have already begun to investigate Mo Ziyan and Su Yamei. I guess there will be definite information tomorrow. ”

"Okay! Brother Yu! You will investigate Mo Ziyan and Su Yamei on your side. Tomorrow my partner and I will go to the school to check carefully, if there is any unexpected findings. I'll let you know as soon as possible. ”

Wu Yu said: "It's okay! It's been two days now. Two students actually died, and the bureau also paid more attention to it. Now we are also working overtime to meet to study the cases of Meng Nan and Jin Shilei. I'm relieved to have your help. ”

"Okay! Brother Yu, I won't bother you anymore. I'll contact you again if I have something. ”

Wu Yu said: "Okay! Go ahead, that's it! I hung up. Contact us in time if you have something. Bye. ”

"Okay, Brother Yu, I know. Bye. ”

After hanging up the phone, I lit a cigarette and carefully thought about the clues that Brother Yu told me. I thought in my heart, according to what Brother Yu said, I must first think about whether the murderer is one person or two people. Was it a serial killer, or was it just a pure coincidence, it was a person who killed Meng Nan. And it was another person who killed Jin Shilei.

Because the methods of the two cases are simply worlds apart, Meng Nan was stoned to death by breaking the skull, although it is brutal, it can be shown that the murderer is absolutely ruthless Meng Nan. To be precise, it is also possible to do a temporary killing. And although Jin Shilei is not so murderous, it is obvious that the murderer has planned it before. And there are no clues around at all. It is clear that the modus operandi of the two modus operandi is not like that of one person.

It occurred to me that the common denominator of the two cases now is that Meng Nan and Jin Shilei are both students at Linji University. Just imagine, a student who has not entered the society, and who can have such a big hatred, first being stoned to death, and then poisoned. It's like killing your father and taking your wife.

I thought to myself: it seems that the only way to find clues is from the school. Maybe you can find some clues. I really can't think of any clues. Hurriedly walked out of the room and came to the hall on the first floor.

Charlie Ba and Sun Tielong were playing something on the computer on the first floor. I thought that Ruohan and Yulin were watching a TV series on the second floor, so I didn't bother them, even if I told them. Rainforest and Wakahan won't help much.

I told Charlie Ba and Sun Tielong directly.

When Charlie Ba and Sun Tielong both knew, the clues to the scene of Meng Nan and Jin Shilei's crimes. Charlie Ba and Sun Tielong also frowned.

Charlie Ba said to me, "It seems. This case is not simple. ”

"Nonsense. How simple is it to kill people and set fires. ”

Sun Tielong said to me, "What do you think about moving forward. ”

"What else can I think, I can't figure it out. I came down to study with you. The only feeling I have now is that the deaths of Meng Nan and Jin Shilei don't want to be done by one person. ”

Sun Tielong said: "Forward, you mean, two murderers?" ”

"Probably so! I'm not sure though. ”

Charlie Ba said: "Forward, I suspect this may have something to do with the peach dispute?" ”

"What do you mean by that, Charlieba?"

Charlie Ba said: "Think about it. Meng Nan and Jin Shilei are both college students now. is also the victim, if it has something to do with money, how much money does it take for the murderer to kill. I guess the odds are low! ”

"Yes, you're analyzing. As for vendettas, how much enmity a student can have, even if there is a vendetta, it can be resolved by fighting. There will be no fatalities. And Jin Shilei's death is enough to prove that it is definitely not a vendetta. ”

Charlie said, "Yes. It's a vendetta, and it's solved with a knife. There is no need to poison it. So I feel that more than 80 percent of it has something to do with women. ”

I also nodded unconsciously
