Brother Song's eyes twitched, and the words that were originally on his lips were swallowed, and his expression was much more serious.

After a moment, he nodded and said, "It is true that this possibility is not ruled out, but the probability is not high.

Normally speaking, the perpetrator's thinking should be to avoid exposing the case as much as possible, so as to choose to destroy and throw the corpse, which is a safer way, just like planting a blame, it really doesn't work, and then think of these methods, as much as possible to get yourself out.

And directly exposing the facts of the case is undoubtedly too risky, unless he is quite confident in his own methods, and at the same time feels that all of us as criminal police officers are wine bags and rice bags, there is no reason to do this.

Although you start from the result that 'we subconsciously ruled out his suspicion of committing the crime', and think that this may be his routine, which is of course a method of reasoning, it is still a little taken for granted.

To sum up, I still believe that he is not the perpetrator of this case. ”

Although he still retorted, his expression was much more solemn than before.

Qi Yuan also understood this truth, nodded slightly, and continued: "Then according to the usual practice, what we have to do next is to find out the source of the corpse and the time of death?" ”

"Hmm." Brother Song answered, took out a cigarette, divided it with him, and squatted on the ground outside the service outlet to smoke.

Qi Yuan looked left and right, and found that during this time, many colleagues came over one after another, and after saying hello to Brother Song, most of them were scattered everywhere, and couldn't help asking, "Brother Song, don't you need to arrange the task first?" Or wait until you're ready? ”

"It's not easy to arrange it now," Brother Song shook his head: "Let's wait for Lao Yan's on-site inspection to be almost done, wipe off the blood stains and other stains, and after taking the photos, the big guys will disperse to visit with the photos, so that the source of the corpse can be confirmed as soon as possible, and then other information about the deceased can be further determined."

Otherwise, if you ask like this, the person being questioned doesn't know what the deceased looks like, naturally, even if you know the deceased, you can't say it, and without this premise, you can only get clues from the relatively generalized questions such as whether you heard strange movements, which is too difficult, and the efficiency of the inquiry is extremely low. ”

"Understood." Qi Yuan bowed.

After waiting for a while, Yan Zhongxin walked over.

"Old Guy," Brother Song immediately stood up and straightened his waist to show respect, and asked, "How is it?" ”

"The survey is almost, a man and two women, looking at the teeth, probably guessed the age of the deceased, the younger one is between the years, and the two older deceased are about the age of the deceased, judging from the grade, it looks like a family of three. It is inferred from this that this case may be a case of extermination.

There is no way to determine the cause of death now, after all, only the skull, no other parts are seen, and there is no life reaction from the neck cut and the cross-section, and the head was cut off after death. ”

Qi Yuan couldn't help but ask, "Then, if you can't find the rest of the body, you can't judge the cause of death, right?" ”

"No, the preliminary speculation should be that there should be excessive blood loss," Lao Yan shook his head: "You see, the muscles of the broken section are slightly pale, which is one of the characteristics of heavy bleeding before death.

The cause of death often produces systemic symptoms, such as the rose tooth phenomenon caused by mechanical asphyxia, and the pale color of the skin and mucous membranes caused by hemorrhagic shock, and the temperature of the corpse is slightly lower than normal.

In the case of dissection, further judgment can be made based on the pathological changes of different parts and degrees of different properties of the brain tissue.

In short, the cause of death is easy to determine, but to determine the fatal wound and draw more clues from it, it is necessary to find a way to find other parts of the body. ”

"What about the time of death?" Brother Song asked.

"The cornea is still clear, there are a small number of scattered corpse spots on the face, the acupressure is fading, the zombie is not obvious, the mouth can be easily pushed away, and the time of sudden death is no more than 12 hours ago." Yan Zhongxin said:

"The more specific time will have to wait for an autopsy to be determined, and in the case of only the head, it is not reliable to speculate on the temperature of the corpse."

"Have you taken all the photos?"

"It's been filmed and sent back to the technical team, let them deal with it simply, don't look so hideous and scary, and send it to everyone."

"Okay, good work." Brother Song nodded again and again, and then asked, "Are there any other injuries to the deceased's head?" Such as scalp injuries, abrasions, and bare hand injuries. ”

"There is a phenomenon of epidermal peeling on the forehead and left side, that is, abrasions. When there is no life reaction, it is a postmortem injury. Yan Zhongxin said: "The basic situation is like this, specifically, let's talk about it after the dissection."

Well, you have an idea, should our forensic department continue to stay at the scene and see if we can collect more corpse parts, or should we go back with these heads for an autopsy first? ”

"Let's go back first." Brother Song said: "If new body parts are found, I will have someone send them back to you." If the scene where the body parts were found is more special, you will be notified to come to the scene to have a look. ”

"Okay, then I'll go back first." Yan Zhongxin shook his head, unscrewed the thermos cup, took a sip of hot tea, sighed with satisfaction, and said: "This ghost weather, if you say that it will cool down, it will cool down, but it is really cold."

You guys too, be careful, don't catch a cold. You haven't eaten yet, have you? Remember to take a hot bite and drink some hot drinks later. ”

"Don't worry, we all know." Brother Song replied with a smile.

Seeing him take the people from the forensic department and leave with his head up, Brother Song led Qi Yuan to Chai Ningning's side and asked, "Sister Chai, how is it, has the investigation been completed?" ”

"The suitcase is very new, and the protective film has not been torn clean," Chai Ningning said, "I guess it should be a new one, just a few days ago." The style is nothing special, and I haven't heard of the brand, it should be produced by a small manufacturer, and in this case, it is too much of a coincidence to want to hit the box.

In addition, there are a lot of fingerprints on the box, but there are also a small number of bloody fingerprints, although they have been wiped, they can still be visible under the luminol reagent, but the lines have been erased. Fortunately, there are still two fingerprints on the inner pad that have not been erased, I took a picture, you see. ”

Brother Song came over to take a look and said, "Look at the lines on the fingerprints, the murderer is wearing knitted gloves." ”

"Well, I should have worn it when I put on my head." Chai Ningning bowed: "However, before that, he must have touched this suitcase, and judging from the blood fingerprints, his cleaning work was also very rough, it is estimated that he has roughly wiped it, and the cleaning is not very clean."

Therefore, the fingerprints on the trunk trolley, box body and protective film, maybe there is another group of his. Go back and collect the fingerprints of the staff of this online store and make an exclusion. By the way, you kept that little young man's fingerprints, right? ”

"Don't worry, all ten fingers are left, and he will be allowed to leave after staying." Brother Song replied.
