"The victim, Jing Lu, was 27 years old.
"The cause of death was mechanical asphyxiation, he was strangled, there was an obvious strangulation on the neck, the strangulation was a flaky epidermal peeling, some purple-red discoloration, the left and right sides of the neck were nearly symmetrical, it is speculated that the murderer strangled the neck with both hands, the left and left neck wounds were large and obvious, and it is presumed that the perpetrator used the right hand, and wore coarse linen gloves when strangling the neck."
"In addition, the deceased's facial signs of asphyxia were obvious, cyanotic and swollen, purple-blue in color, there were large scattered punctate hemorrhages in the conjunctiva of the eye and oral mucosa, and the tip of the tongue was slightly exposed outside the dentition, accompanied by minor bites.
Also, the rosette phenomenon is evident, which is a typical sign of mechanical asphyxiation. ” After a pause, she added, "Oh, one more point.
The victim had no resistance injuries to his limbs, but had a large patchy indentation in the lumbosacral region with epidermal exfoliation. ” It is assumed that the victim was asleep and strangled by the murderer riding on his waist.
Because his body was covered with a towel quilt, when he was ridden by the murderer, his limbs were bound by the towel, so he was powerless to resist. ” "That's pretty much it.
Do you have anything to ask?"
"No, it's hard work."
Yuan Youchong shook his head.
Zhou Qianxin smiled lightly and said, "Then I'll take the corpse back for autopsy first." ” "Well, let's go back first."
Seeing Zhou Qianxin put the body into a body bag, Yu Yuan and the others found Cheng Wei again and asked if there was anything found in the trace examination at the scene.
Cheng Wei shook his head: "No suspicious footprints were found at the scene, and the fingerprints were all extracted, but Xiao Zhou said that the murderer was wearing gloves when he committed the crime, and it is estimated that the fingerprints at the scene were not his." ” In addition, there are a few faint traces of dust similar to footprints on the quilt, but there are no patterns on it, and it is estimated that the perpetrator was wearing shoe covers when he entered the scene.
Based on the traces left by the shoe covers, I can barely deduce the shoe size, and then roughly determine the height of the murderer. ” "But the imprint on the quilt can't be used for gait analysis, nor can it calculate the stride distance or anything, plus the shoe size obtained in this way is originally a guess value, so the error will be very large, in extreme cases, it can even reach an error of fifteen to twenty centimeters, which is almost unusable."
"That's it" Yuan Youchong frowned and said, "Okay, then you can check the scene carefully and see if you can find some clues." ” "Okay."
Outside the scene, the two lit cigarettes.
Yu Chen asked: "You said, Jing Lu's death and Feng Kangying's murder, is there any connection between these two cases?"
"It's hard to say."
Yuan Youchong shook his head: "But, Dai Sheng shouldn't be able to get out of it." ” "Nothing to do with that case" "I can't take it off."
Yuan Youchong said: "I am now sure that his previous appearance of being dumb and upright, and without scheming, was simply pretended. ” "yes."
Yu Chen pouted: "Don't say anything else, when we knocked on the door earlier, that guy was pretending to be asleep at all, until my fingers touched his neck, he was a spirit, and he couldn't help it anymore, so he had to make a look of waking up." ” "In the interrogation room, he asked us to send someone to protect him and install a camera at the door, the fundamental purpose is to borrow us to give him an alibi, otherwise, there is no way to explain his previous abnormal and contradictory behavior."
"This guy is still thoughtful."
Yuan Youchong sneered and said.
Yu Chen hummed, agreed, and then asked: "But, even if he has such and such arrangements, it can only mean that he is inseparable from Jing Lu's death, and what does it have to do with Feng Kangying's murder case?"
"It's a big deal."
Yuan You flicked the ashes of his cigarette and said, "If he hadn't been involved in Feng Kangying's murder case, he was a framed person, and he was investigated and interrogated by us, how could we send someone to keep an eye on him and even protect him openly?"
"And, if there is no prerequisite, how can he use us as his alibi, if there is no alibi, with the contradiction between him and Jing Lu last month, he will naturally be listed as the first suspect by us" "Hey, you've got a weird brain circuit."
Yu Chen interrupted him and said, "Even if he has an alibi, we don't suspect him the same."
"It's different."
Yuan Youchong shook his head and said: "If he does not have an alibi, based on his previous conflict with the victim, we have sufficient reasons to summon and interrogate him, and issue a search warrant to conduct an in-depth investigation and dig up clues and evidence." ” "But now it's different, unless we have clear and direct evidence pointing to him, otherwise, if we want to investigate his relationship with this case, we can only obtain his consent and ask him to cooperate, and the investigation is much more difficult.
It can be said that he has already grasped a certain degree of initiative. ” Yu Chen sighed, and said: "Reason is a little reasonable, but he can't kill a baby who has nothing to do with him in order to take revenge and kill Jing Lu."
"If you want me to say, Jing Lu's death, he really can't get rid of it, and even he can't be the perpetrator or one of the perpetrators, but Feng Kangying's murder should have nothing to do with him."
"You think, before a person plans to kill someone, he should avoid attracting our attention as much as possible, even if he wants to create an alibi, there are many methods, why take risks" "Then, we don't look at the process, we only look at the result."
Yuan Youchong said: "Jing Lu's death, he has an alibi, Feng Kangying has no direct connection with him, and at the time of the crime, he also had an alibi, and the investigation against him can be said to have found nothing." ” "From this point of view, can it be understood that he has already picked up all of his picks, according to my guess, although his method is a little more dangerous, but undoubtedly, for now, he has succeeded."
"Some people are so rampant, not to mention attracting our attention before committing the crime, but using us to eliminate their suspicions, and even directly provoking our criminal police, deliberately giving our criminal police clues, or all kinds of other show-off methods, it is not uncommon, what is he?"
"Besides, I didn't mention that he was the perpetrator of Feng Kangying's murder, I just said that he couldn't get out of it, otherwise these two seemingly unrelated cases have intersected with him, which is too much of a coincidence."
"Okay, I'll not tell you that for now, let's go back to the case itself."
Yu Chen saw that he and Yuan Youchong had their own opinions, and neither of them could convince each other, and each had a reason, so he also gave up the idea of continuing to fight, and said: "The problem now is, let's be suspicious, but Dai Sheng does have an alibi, how can we break through the "punishment and murder
