Chapter 715 Strange Scratches

The house covers an area of ​​75 square meters. From the moment you enter the door, there are dots of blood stains on the white walls.

Blood was splattered, even on the ceiling.

Jiang Yang carefully walked through each room carefully.

Gao Jianmu slowed down and followed him. After hearing his question, he sighed helplessly: "The forensic doctor said this was left when the deceased fought with the murderer. The blood stains extended from the bedroom to the living room and all the way to the bathroom."

"Looking at the trajectory, Tian Xiaoyang has been struggling, but it doesn't help."

Usually the fighting is back-and-forth, and both sides are determined to kill the other side. It is rare that only one side is injured.

Unless it is crushed by unilateral strength.

Jiang Yang walked around in a big circle before finally entering the bathroom where the body was found.

The water in the bathtub had already been sampled by the forensic department, and the blood stained red was still there.

But it smells bad.

A little breath fills the nasal cavity.

"Really? Apart from traces of the deceased's blood, are there other people's blood at the scene?"

Jiang Yang asked.

There was really too much blood splattering out sporadicly, and the bathroom was even more crowded.

Not only was there a pool of blood, but there was blood on the floor tiles, wall tiles, on the glass and behind the door, etc. There was blood everywhere.

What's even more exaggerated is that the cabinet under the sink has a big crack.

As a result, the ceramic sink cannot be hung and is teetering, looking like it will collapse soon.

However, according to the autopsy report, there were no fingerprints or skin flakes left around the sink.

The situation itself is abnormal.

It shows that the murderer has handled the crime scene and is very thoughtful.

"No."

Gao Jianmu shook his head regretfully.

At this time, Gao Jinyang and others also entered one after another. Everyone was cautious and gentle for fear of touching something and damaging the crime scene.

"Hey! What's going on? The height of this building is about 2.8 meters, right? How can the blood jump so high?"

Gao Jinyang raised his head and stared at the ceiling lamp above his head in surprise.

Large swaths of blood gathered on the lampshade, with a few drops on the ceiling.

"I don't know."

Gao Jianmu was helpless, "Colleagues from the identification department reconstructed the crime scene several times, and initially determined that the place where the deceased died was in the living room."

"The murderer killed the deceased with two stabs, and then stabbed him four times as if to vent his anger. The blood was spattered on it."

"After confirming that Tian Xiaoyang was dead and the murderer finished venting his anger, he dragged his body into the bathtub, filled it with water, and finally chopped off his right palm."

"No DNA from other people was found in the floor drains or sewers. Not only did the murderer have a high level of force, but he also had a quick mind."

Jiang Yang nodded and added: "He knows the police's case handling procedures very well."

"right."

Gao Jianmu agreed.

"The conclusion given by the psychological profiler is that the murderer is very interested in suspense movies and has excellent understanding and learning abilities. He clearly knows the structure of the human body and is enough to hit the heart with one blow. He is very likely to be highly educated. "Big, Zhang Ying was not excluded at first, because she was highly consistent with these two points. As for strength, we suspected that the murderer might have used external equipment."

Having said this, Gao Jianmu pursed his lips, "Everyone, pay careful attention to the bathroom floor tiles. There are several light scratches on them. The marks are very new and should have been left recently. The blood can be splashed everywhere, indicating that at that time The murderer was very violent. It would have been easier if there were outside help. After the corpse was dissected, the heart was stabbed to pieces."

"What hatred is there for this?"

Zeng Gaojie didn't understand, "What's the use of stabbing so many people when they're dead? What can a corpse feel?"

"Who knows, we are not murderers, so it is normal not to understand. Anyway, as long as the case is solved, there will be ways to make him explain clearly."

Ji Dayu answered, "Since it's just to vent his anger, does Tian Xiaoyang have any enmity with anyone?"

"No."

Gao Jianmu sighed again.

The Criminal Investigation Team's questions have been investigated one by one.

But what is surprising is that all the clues are interrupted every time they reach a certain place, and there is no way to go deeper.

For example, Tian Xiaoyang’s interpersonal relationships.

"The deceased had a cheerful personality and liked to make friends. He had no grudges with the people around him. Not only did he not have any grudges, he often helped classmates who were in need. There were three people in the class who borrowed money from Tian Xiaoyang."

"The amount is not large, it's like three to five thousand. It was paid off before the deceased's accident."

So it can't be a financial dispute.

Jiang Yang remained silent and did not speak. While quietly listening to Gao Jianmu's analysis and summary, he recalled the relevant files. The interpersonal relationships of the four deceased were not complicated.

Even Tian Xiaoyang, who is more playful, is a regular playmate.

Only Zhang Ying is the biggest variable.

Does the key still have to be found in her?

Everyone is now very enthusiastic about this difficult case.

They all want to solve the case as soon as possible and understand the importance of the case to the country.

Be sure to detect it before the National Day holiday.

The province will be in chaos when the time comes, allowing the murderer to escape.

Time was running out, so everyone chatted for a few words before returning to the topic.

Jiang Yang was confused, "You said that the murderer might have used external instruments. Have you found out what these traces are? Those that can leave traces on hard floor tiles are more likely to be metal."

He squatted down and pointed at the faint scratches, "But to leave so many marks, there must be a lot of noise. The scratches are from the bathtub to the bathroom door."

"It's less than three meters, and it takes an adult about five to six seconds to ten seconds?"

Seeing everyone nod, Jiang Yang said, "The sound insulation of the old house is average. The window of the bathroom at the crime scene was open. Did the neighbors mention hearing a particularly harsh sound?"

"Well, I asked, but they all said no."

Gao Jianmu continued to shake his head.

"What is this?"

Wearing gloves, Jiang Yang gently touched the scratches on the floor tiles.

He has excellent five senses and can clearly see several irregular deep pits when he gets close.

It is deeper than the surrounding scratches, like a pit caused by a hard object falling.

"Not sure, it may be a bump left by the murder weapon."

Gao Jianmu said, "The identification department has detected the residual metal substance in this scratch, which is a commonly used alloy manganese steel."

Jiang Yang tilted his head and looked at it for a while, always feeling that this mark was not complete.

"Did you take pictures?"

"Yes, I did. They are all in the evidence bag."

Gao Jianmu didn't know why Jiang Yang was so obsessed with a small bump, but he knew that details were often needed to solve a case.

"Take a few more pictures."

Jiang Yang reached out to take the camera and took several pictures from different angles before giving up.

After a round, there were still some clues.

"Let's pack up. Everyone has not slept all night. Go home and adjust your state."
