He also pointed to the blood stains on the floor and said: "There are four pools of blood on the ground, and they roughly outline the outline of a human figure, which can restore the posture and position of the four adult victims when they were first killed."
"They were not far apart, and they should have been killed one after another in a short period of time, or lost consciousness, at least they didn't run out of the house."
"The throwing blood stains on the furniture and walls have obvious tails, which should have been thrown off by the murderer when he wielded the murder weapon, and the direction and approximate speed of the throwing can be inferred from this."
In addition, there was a splattery of blood on the wall, and among the victims, Yi Langyuan had his throat cut, suspected to have been cut in the carotid artery, and these blood marks should have been splattered from his carotid artery.
The blood stains on the ground in the corner of the room are diluted, presumably left by the murderer's cleaning of the murder weapon and the blood stains on his body. ” "However, no suspicious footprints and fingerprints were found at the scene, and they should have been cleaned up by the murderer."
Speaking of this, Cheng Wei concluded: "To sum up, when the murderer entered the scene, Yi Langyuan's family should have been getting together to marry the two children. ” "They may have been a little surprised to see the murderer, but they didn't pay much attention to it.
As a result, the murderer suddenly burst into a crime, and when they could not react and panicked, they killed them one by one, or used some means to make them lose their sense of autonomy. ” "Only in this way, after they are killed, the distance between the bodies is not too far."
"Your speculation is a bit taken for granted."
Yuan Youchong shrugged: "If the murderer closes or blocks the door with his backhand when he enters the room, where can the victims escape to, the indoor space is so large, and the place of murder is naturally not far away." ” Cheng Wei knew that Yuan Youchong's reasoning ability was far stronger than his own, and he didn't quibble, and said: "Of course, there are many possibilities, and I just put forward one of them based on the results of the trace examination for your reference." ” "Hmm."
Yuan Youchong didn't mean anything else, so he nodded.
Later, he asked, "Didn't find any suspicious footprints at the scene, right?"
"It's not just suspicious tracks, it's just that footprints are scarce."
Cheng Wei replied: "There are only three kinds of footprints at the scene, and they are all limited to the entrance area, which should be the informant and the two police officers stationed in the village."
It shows that after the murderer committed the crime, he carefully cleaned the footprints and fingerprints at the scene, but he didn't care about the bloodstains, perhaps because he knew that there were too many bloodstains and couldn't clean them up at all. ” "I have an idea."
Zhou Qianxin suddenly interjected: "The murderer killed several people in a row, and the soles of his shoes couldn't have been stained with any blood, even if he washed his shoes by the way when he cleaned the murder weapon, at least on the way he walked to the faucet, there would be bloody shoe prints." ” He may have discovered this, and after cleaning the murder weapon, he wiped the soles of his shoes clean, and then wiped the bloody shoe prints, footprints, and possible fingerprints on the ground.
However, even if the blood stains have been rinsed or even repeatedly rinsed, they can still be made visible by special methods. ” "That's right."
Yuan Youchong nodded and said, "Take the luminol reagent." ” Cheng Wei's eyes lit up, luminol reagent is extremely sensitive to hemoglobin, and contact with it can produce a fluorescent reaction, even after repeated scrubbing of blood stains can be detected, it is one of the commonly used reagents in forensic and trace examination work, he is naturally prepared.
Several people lowered the curtains of the scene to make the scene appear dim, and then Cheng Wei sprayed the reagent on the ground.
Soon, several clusters of fluorescence appeared on the ground, and Cheng Wei hurriedly took a few photos.
Then, Yuan Youchong squatted down, carefully measured and observed, and said, "Judging from the speed of fluorescence generation, there is no doubt that it should be blood."
Although applied, the general outline and pattern of the sole are still visible. ” "The silhouette length is 255 cm, which is a size 41 shoe according to the old shoe size in the mainland.
The pattern pattern of the sole is regular, thin and dense, and the sole surface should be flat, which may be a skate or leather shoe. ” As soon as he finished speaking, the fluorescence gradually dimmed and disappeared.
He took the camera in Cheng Wei's hand and continued to observe, saying: "The footprints are spaced between no more than two and a half shoe prints, about sixty centimeters and above. ” Cheng Wei took the camera back and nodded his head.
Yu Chen continued: "The shoe size is 41, the footstep spacing is about 60 centimeters, and the murderer's height should be around 1.7 meters." ” "Almost."
Yuan You rushed back, then pointed to the blood stains on the furniture and walls, and said to Fan Yuhong: "Old Fan, you and Lao Cheng immediately determine the throwing point of the blood, that is, the murderer's attack point, based on these throwing shapes, splashing shapes, and splash blood stains. ” "Understood" both nodded in response, and went about their jobs.
Subsequently, Yuan Youchong said to Zhou Qianxin: "Xiao Zhou, you continue to conduct the autopsy. ” Yu Chen immediately asked: "Then what about me, what am I doing?"
"You" Yuan Youchong blinked, and after thinking for a long time, he suddenly realized: "Ah, there is really an important thing for you to do."
"Oh" Yu Chen was curious, and a little expectant: "What's the matter?"
"Get out of the way, don't get in the way."
His face turned purple, and he couldn't help but shout: "I'll go to your uncle's labor and management to be the head of the criminal investigation detachment, so it's useless."
"No, of course not."
Yuan Youchong explained seriously: "Your ability is very comprehensive, which is very similar to me, and there is some overlap, but I am much better than you in all aspects, so with me, you are useless." ” "Oh no, you're very strong, you're very good, be a bodyguard" "Dirt" Yu Chenqi's seven orifices smoked: "I'll just say it if I belittle, but it's still serious" "Because what I'm saying is the truth."
"Fact, your uncle, I'm prying" At this time, Zhou Qianxin suddenly interrupted them and said, "Team Yu, Team Yuan, don't flirt here, listen to me." ” Yu Chen was speechless, glaring at her angrily: "Say" "The phenomenon of Yi Jianliang's corpse is very similar to Xin Hanjun."
Zhou Qianxin said: "Their deaths may have been committed by the same person. ” Yuan Youchong nodded and said, "Sure enough, someone is designing Yi Langyuan's family."
Can give the investigator" "The direction is out."
Yu Chen interrupted him, perhaps because he was a little unwilling to be despised before, and was eager to prove his authority and ability as the leader of the detachment, and immediately said: "The focus of the investigation is to find out who dug up, or tricked Yi Langyuan into digging up Xin Hanjun's body, and marrying Yi Jianliang." ” "Didn't get to the point."
Yuan Youchong glanced at him and said lightly: "I think that a middleman is also needed for a secret marriage, whether he is a man or a woman, let's call it a dead woman first."
Our task is to find out this underworld woman "torture and murder
