Within a few minutes, Liu Donghe rushed to the scene of the crime, which had been surrounded by the police, they saw Liu Donghe coming and automatically gave way to a road, Liu Donghe walked to the front and first observed the surrounding situation, this is the back of the teaching building, located under the window of the men's bathroom on the first floor, he glanced at the bathroom, there are already police standing guard inside, although the teaching building is not on the edge of the school, but because there are almost no people coming behind this teaching building, so the body is only found now.

Liu Donghe took a closer look at He Weibo again, he died very miserably, there were ten sharp knives inserted under the bathroom window, seven of which were submerged in He Weibo's body, and He Weibo's head was gone, but there was Sun Wen's lost head on He Weibo's body.

It's another homicide case without a head, is it because our direction is wrong again, impossible, now all the evidence is ironclad, so where did He Weibo's head go?

"Damn, is this guy going to be our policeman dead, how many people is he going to kill." Liu Donghe scolded angrily

"Section Chief Liu, judging from the modus operandi of the homicide, the homicide in this case and the homicide in the first two cases are not one person, you can come and see." A forensic doctor who was collecting evidence heard Liu Donghe's scolding, turned to him and said, and when Liu Donghe walked up to her, she turned around and continued, "This homicide case has many differences from the previous two homicides, first, in terms of the amount of blood sprayed in the neck cavity, the first two were beheaded by a living body, and this one bleed so little that it was obviously beheaded after the person died, and second, among the seven knife wounds on this corpse, only one was fatal, that is, this one, which inserted the deceased's collarbone and cut the deceased's subclavian artery, Judging from the amount of bleeding from the wound and the traces of being scratched at the scene, the deceased did not die immediately after being severely injured, but struggled in the early stage and fell into a coma due to excessive blood loss in the later stage, and the whole process took more than half an hour, so that is to say, the murderer waited at least half an hour before cutting off the deceased's head, the third difference is the means of committing the crime, you see that there are many slashed knife wounds on the neck cavity and chest of He Weibo's body, according to my test, these knife wounds were cut after the death of the deceased, And there are also multiple knife wounds on the bones above the neck cavity, which shows that the murderer's hands were shaking when he cut off the deceased's head, and his strength was not enough to cut off the deceased's head with one knife, it just so happened that Sun Wen's head was also here, you can see that these two knife cuts are not different at all. So, based on the above points, I can be sure that this case is not the same murderer as the previous two cases. ”

"When is the time of death?" Liu Donghe then asked

"The time of death was determined from liver temperature to be between 4 and 6 a.m." The medical examiner replied

"Who first found out, man?"

"It was discovered by a boy who went to the bathroom, and now he has gone to the hospital because he was stimulated, and it is also the first time that anyone who sees this kind of scene can't stand it." The medical examiner replied

"Is there anything else that can be investigated at the scene?" Liu Donghe asked

"Section Chief Liu, we are not machines, how much can we know with our eyes, and other clues will have to wait for us to go back to check, and report to you tomorrow." The medical examiner laughed

"Tomorrow, isn't it too late?" Liu Donghe said

"There's no way, there are too many clues this time, you look at this place, it's land without cement, it's a little difficult to collect evidence, but this is more evidence than the cement road, and the murderer walked when it was almost dawn, so there should be no time to clean up the scene."

"Okay, I see, thank you." After Liu Donghe finished speaking to the forensic doctor, he then said to Liu Hai and Zhang Yulang next to him: "Liu Hai, you go to the hospital to see that boy, it's best for you to get his transcript at one time, Yulang, you go to see this bathroom and block this teaching building." ”

"You don't have to work in vain in the bathrooms and school buildings, even if there are clues, so many hours have passed now, and the people have already been destroyed." The medical examiner said

"Oh, okay, did you find any suspicious people around the fisherman?" Liu Donghe asked

"Not for the time being, but I think the murderer should be nearby, and he can't run around with a person's head in broad daylight, right?" Zou Ping leaned over at this time and said

"I think so, otherwise this person has a really strong taste." Zhang Yulang said

"This is a university, and there are many people and rooms, which is not conducive to investigation, hey, yes." Liu Donghe suddenly thought of something, and then said: "There should be a doorman in the teaching building, didn't he hear a little movement last night?" ”

"I already have a colleague to take notes, and I guess it will be done in a while." Zhang Yulang said

"Well, I know, now the substitute has also come, Zou Ping, you call Liu Hai and tell him to go back to rest directly after going to the hospital, fisherman, you go back first." Liu Donghe said

Although there is a new situation in the case, but the comparison people are not iron-clad, they haven't slept much in the past two days, Liu Donghe sent them away, and he went to the previous hotel again, he was really tired, tired and didn't even have the strength to go home.

He slept very deeply, he didn't even hear his son call him, Liu Donghe didn't wake up from his sleep until more than eleven o'clock in the evening, looked at the mobile phone, and his son actually called him more than 11 times, Liu Donghe gave his wife a call to ask about his son's situation, and when he learned that his son had just fallen asleep, he felt ashamed of his son.

Liu Donghe washed his face and went out to see how the other colleagues were investigating, but he was not surprised when he knew that there was no progress, because although this place is full of people and many rooms, it is not good for the police, and it should also be unfavorable for the murderer, if it can be discovered, it will be discovered long ago.

Liu Donghe roughly turned around, seeing that there was nothing wrong, so he had to drive home first, first, the forensic report will not come out until tomorrow, and second, he hasn't seen his son for several days, and he can take a look tomorrow morning, and now the case is so tight, he doesn't know when he will be able to go back again.

At seven o'clock the next morning, Liu Donghe walked into the office of the Third Criminal Investigation Division, and to his surprise, his subordinates came earlier than him today.

"The sun is coming out in the west today, why did you all come early?" Liu Donghe smiled at them

"I can't sleep, this murder is one after another, and it takes a lot of heartless people to sleep soundly." Zou Ping said

"Zou Ping, you go and get the autopsy report back now, let's study it." Liu Donghe said to Zou Ping

"I went to see it just now, and it won't be until ten o'clock to get out there, and it's almost time in a while, so I'll go over and get it." Zou Ping said

"Did you find any clues in the things you brought back from He Weibo's room yesterday?" Liu Donghe asked

"In addition to a footprint, we also found a hair, which also belongs to a woman, it should have fallen when the person was rummaging through things, as for the diary, there is no second person's fingerprint except for He Weibo's fingerprints, and the bloodstain test report in the refrigerator came out, and it was determined that the bloodstains in the refrigerator were Li Shanshan and Sun Wen's, that is, the heads of the two of them were once stored in this refrigerator, as for whether this woman has anything to do with the previous two murders, no evidence has been found yet." Zou Ping said

"Well, okay, I know, you can go over and wait for He Weibo's autopsy report and the inspection report of the crime scene now, if there is anything you can help, try to help the report come out as soon as possible." Liu Donghe said to Zou Ping

"Okay." Zou Ping finished speaking and left the office

When it was almost ten o'clock, Zou Ping came back with a stack of documents, and at first glance, she couldn't hide the excitement in her heart.

"What's wrong, stupid by the case? Why are you still happy? Bangs said

"What do you know, this is going to be a big discovery, section chief, report to you." Zou Ping said and handed the report to Liu Donghe.
