"have no idea."

After taking a few breaths, Old Wei shook his head slightly and said: "There are a lot of fingerprints and other traces in the tower crane operating room, and they have all been extracted and fixed. But... if it is confirmed that the body was hoisted up by that old Bi If so, then these traces will have no actual value."

Su Ping nodded slightly, not surprised by this.

When someone inside brought Lao Bi over, Su Ping had expected it. After all, the inspection of the operating room was only to identify the operator, and at this time the operator had been identified in advance...

"Stand by for now." Su Ping said, "In a short while, you may be able to find something new that requires your investigation."

"Okay." Old Wei naturally had no objection and just stood aside.

After a while, he also noticed the victim's fingerprints. He couldn't help but let out a sigh, leaned forward and stared at the victim for a few seconds, and said: "This guy's fingerprints..."

"We just mentioned it." Tu Zhongxin said: "This person's fingerprints are strange. He may be a fugitive or something else. Lao Su said that we should leave it alone and find a way to confirm his identity."

Then he shook his head and stood up, and continued: "Preliminary judgment is that the victim died between ten and eleven last night, about ten hours ago, and the cause of death was traumatic shock caused by ruptured internal organs at that time.

In addition, the victim had numerous scars on his body, which spanned a long period of time. Some of the scars had initially healed, and restraint injuries were visible on his limbs... Therefore, we cannot rule out the possibility that multiple people committed the crime, or even multiple people committed the crime multiple times."

Su Ping clicked his tongue and then asked: "This 'multiple people'...how many people are they?"

"Based on the shape and severity of bare-hand injuries and blunt force injuries on the body, I'm afraid there are at least two people, one with great strength and the other with less strength." Tu Zhongxin replied: "The time span should be about forty-eight hours, and there will be no deviation. too much.

In terms of the number of times...at least three times, at most five times, there were three types of injuries. Judging from the shape of the injuries and the degree of healing, they were not separated by a long period of time, but the 'technique' has changed."

Su Ping silently opened his notebook.

So Tu Zhongxin went on to say: "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 was injured on the back of his head. It was speculated that he was attacked from behind by the murderer himself. He was hit on the back of the head with a brick three times, causing the victim to fall into coma. The murderer then kicked him several times and pulled him away, leaving some scratches and bruises. Except for the damage to the back of the brain, the rest of the injuries have recovered a lot."

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

"Let's count the five injuries. The second, third, and fourth injuries should have occurred between the night before yesterday and early yesterday morning, about 24 hours from the time of death." So Tu Zhongxin looked down at the body and continued. :

"At this time, the victim's wrists were restrained and hung up. His fingers and limbs were severely ischemic, and small areas of necrosis appeared. He was hit twice with sticks and once with bare hands. The beating areas were concentrated on the thighs and torso. He was hit twice with sticks. There is a certain amount of time between, but it’s not too long.”

Old Wei raised his eyebrows and muttered: "Can you see this?"

"Mainly, the 'sticks' used in the two stick blows are not the same, and the physiology and pathological morphology of the injury site are quite different, making it easier to judge." Tu Zhongxin explained:

"There was a long strip of intradermal bleeding in part of the hit area of ​​the deceased, which was heavier in the center and gradually lighter on both sides. The border was relatively blurred and unclear. There was also hollow intradermal bleeding in the abdominal injury, and there was no obvious epidermis in the injured area.

exfoliation.

In summary, carefully combining the characteristics of the injured area with the shape of the long bleeding band, this part of the injury should be caused by a cylindrical stick with a relatively smooth surface, and the stick is wooden, with a larger diameter, thicker at the top and thinner at the bottom, possibly a baseball bat.

;

The other part of the injury was mostly a well-demarcated, uniformly wide band-shaped intradermal hemorrhage, about 3.8 centimeters wide, accompanied by island-like epidermal exfoliation. Hollow intradermal hemorrhage was also seen in the chest and abdomen.

In addition, there was some groove-shaped hollow subcutaneous bleeding. The hollow was nearly rectangular, about 3.7 cm long and 0.6 cm wide. There were also some strip-shaped abrasions and contusions, and the center of the injury was obviously heavier.

In summary, it can be determined that this part of the injury was a flat, mostly uniform but partially rough square cylindrical stick with a width of about 3.5 to 4 centimeters and a thickness of about 0.5 to 1 centimeter. Specifically,

I can't think of anything for a while.

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

Su Ping nodded slightly, expressing understanding.

After quickly glancing at the notes, he then asked: "Where is the other bare-handed injury?"

Tu Zhongxin glanced down at the body again to help him recall, and then continued:

"There is nothing to say about the bare-hand injuries. They were just punches and kicks. The punch injuries were mainly concentrated on the face, while the kick injuries were concentrated on the victim's legs. Judging from the appearance of the corpse, there was no substantial threat to the victim's life. At most, it was

A minor injury.

However, it can be seen from this that the perpetrator was also weak and did not know how to box. He may have attacked the victim purely to vent his anger."

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

"It's a high probability, but we don't rule out love murder." Tu Zhongxin said: "There is also a possibility that the murderer is a pure violent maniac."

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

Tu Zhongxin raised his eyebrows: "What's wrong?"

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

"The last time was relatively long, and it should have been the cause of death last night." Tu Zhongxin added: "This time it was still a bare-handed injury, but the murderer was much stronger, and his attacks were extremely heavy, and they were all aimed at the deceased.

He was hit on the chest and abdomen, and at least two of his ribs were broken."

Qi Yuan flipped through his notes and asked: "Is it this attack that caused the deceased's internal organs to rupture, and ultimately led to death from traumatic shock?"

"Yes, but we are not yet sure whether the rupture was the liver or the spleen." Tu Zhongxin said: "The two internal organs are relatively superficial. The human bones and muscles do not protect them well, and the blood vessels themselves are extremely rich. Once

If it is hit by a large external force, it is likely to break and lead to rapid death of the human body."

Su Ping made a sound of understanding and said: "If the on-site investigation is almost complete... just take the body back."
