"I don't know."

After taking two breaths, Lao Wei shook his head lightly and said, "There are a large number of fingerprints and other traces in the tower crane operation room, which have been extracted and fixed. But...... If it has been determined that the body was hung by the old Bi, then these traces have no practical value. ”

Su Ping bowed his head slightly, not surprised.

When someone inside twisted Lao Bi over, Su Ping expected it. After all, the survey of the operation room is only to determine the operator, and the operator has already been identified in advance......

"Let's be on standby." Su Ping said: "After a while, you may be able to discover something new that needs to be investigated." ”

"Okay." Lao Wei naturally didn't have any opinions, so he stood aside.

After a while, he also noticed the victim's fingerprints, and couldn't help but sigh, leaned over the first two, stared at them for a few seconds, and said, "This guy's fingerprints ......"

"We just mentioned it." Yan Zhongxin said: "This person's fingerprint is abnormal, it may be a fugitive, or it may be something else." Lao Su said that he would leave it alone for the time being, and find a way to confirm his identity. ”

Then he shook his head and stood up, and continued: "It is preliminarily determined that the victim died between 10 and 11 o'clock last night, about ten hours ago, and the cause of death was traumatic shock caused by the rupture of internal organs at that time.

In addition, the victim had a lot of injuries on the surface of his body, and the time span was also long, some of the injuries had been initially healed, and restraint injuries were visible on his limbs...... Therefore, it cannot be ruled out that many people may commit crimes, or even multiple people commit crimes many times. ”

Su Ping sighed, and then asked: "This 'multi-person'...... How many people? ”

"Judging by the form and severity of the bare hand injuries and blunt force injuries on the body surface, I am afraid that there are at least two people, one of whom is extremely powerful and the other is less powerful." Yan Zhongxin replied: "The time span should be about forty-eight hours, and the deviation will not be too much."

Number of times...... At least three times, and at most five times, there are three types of injuries, and judging from the shape of the wounds and the degree of healing, the interval between them is not long, but the 'technique' has changed. ”

Su Ping silently flipped through the notebook.

So Yan Zhongxin continued: "The first injury should have occurred sixty hours ago, or forty-eight hours before death, that is, the night before yesterday.

At this time, he suffered a blow to the back of the head, presumably by the murderer himself from behind, and slapped him on the back of the head with a brick, hitting him three times, causing the victim to fall into a coma, and then the murderer kicked him several times and pulled away, leaving some abrasions and bruises, except for the back of the head injury, the rest of the wounds have recovered a lot. ”

Su Ping wrote it down, nodded, and motioned for Yan Zhongxin to continue.

"Based on the five injuries, the second, third, and fourth should have occurred between the night before yesterday and the early hours of yesterday morning, about twenty-four hours before the time of death." So Yan Zhongxin looked down at the corpse, and continued:

"At this time, the victim's wrists were restrained and suspended, the extremities of the fingers were severely ischemia, and there was a small part of necrosis, and he was hit with two sticks and one with his bare hands, and the beating area was concentrated in the thighs and torso, and there was a certain time interval between the two stick blows, but it was not too long."

Lao Wei raised his eyebrows and muttered, "Can you see this?" ”

"The 'sticks' used for the two main stick strikes are not the same, and the physiology and pathological morphology of the injury site are quite different, so it is easier to judge." Yan Zhongxin explained:

"There were long strips of intracutaneous hemorrhage in some of the parts of the deceased who were hit, the central part was heavier, the sides gradually lessened, the border was relatively blurred and unclear, the injury in the abdomen and hollow intracutaneous hemorrhage, and there was no obvious epidermal exfoliation at the wound.

In summary, carefully combining the characteristics of the injury site and the shape of the elongated bleeding zone, this part of the injury should be caused by a cylindrical stick with a relatively smooth surface, and the stick is wooden, with a large diameter, thick at the top and thin at the bottom, and may be a baseball bat;

The other part of the injury, most of which is a well-defined, uniformly wide banded intradermal hemorrhage, about 3.8 cm wide, accompanied by isolated epidermal exfoliation, and hollow intracutaneous hemorrhage can also be seen in the thorax and abdomen.

In addition, there are some grooved hollow subcutaneous hemorrhages, which are nearly rectangular at the hollow, about 3.7 cm long and 0.6 cm wide; In addition, some strip-like abrasions and contusions exist, and the center of the injury is obviously more severe.

To sum up, it can be determined that this part of the damage is a flat, mostly uniform but locally rough square cylindrical stick, about 3.5 to 4 centimeters wide and about 0.5 to 1 centimeter thick, and I can't think of anything specific for a while.

By the way, this part of the injury is relatively light, and it can be judged that the strength of the injured person is relatively weak. ”

Su Ping bowed his head lightly, expressing his understanding.

After a quick glance at the note, he asked, "What about another unarmed hand injury?" ”

Yan Zhongxin glanced down at the corpse again, helping to recall, and then continued:

"There is nothing to say about the bare hand injury, just punches and kicks, the boxing injuries are mainly concentrated in the face, and the foot kick injuries are concentrated in the victim's legs, judging from the condition of the corpse, there is no substantial threat to the victim's life, at most it is a minor injury.

However, it can be seen from this that the perpetrator is also less powerful and does not know boxing, and may have attacked the victim purely to vent his anger. ”

"If you vent your anger, can you be sure that this case is a vendetta?" Qi Yuan asked out loud.

"It's probable, but it's not ruled out." Yan Zhongxin said: "There is also a possibility that the murderer is a simple violent maniac. ”

"Violent madness......" Su Ping pinched his chin and muttered these three words.

Yan Zhongxin raised his eyebrows: "What's wrong?" ”

"It's fine." Su Ping waved his hand, and then asked, "What about the last time?" ”

"The last time was a long time apart, and it should have been the cause of death, last night." Yan Zhongxin said again: "This time it was still a bare-handed injury, but the murderer was much stronger, and his hands were extremely heavy, and they were all hit on the chest and abdomen of the deceased, and at least two ribs could be broken. ”

Qi Yuan flipped through his notes and asked, "Was it this attack that caused the deceased's internal organs to rupture, and finally caused the death of traumatic shock?" ”

"Yes, but it's not sure for sure if it's the liver or the spleen that ruptures." Yan Zhongxin said: "The parts where these two internal organs are located are relatively superficial, the human bones and muscles are not very well protected, and the blood vessels themselves are extremely rich, once they are hit by a large external force, they are likely to be broken, and lead to the rapid death of the human body." ”

Su Ping snorted, expressed his understanding, and said, "If the on-site investigation is about the same...... Just take the body back. ”

"I'll take some pictures first." Lao Wei said loudly: "The victim's fingerprint is missing, I'm afraid we can only collect clues from the society through photos." ”1603375425
