Chapter 716 New Common Ground

Jiang Yang made the decision and let the criminal investigation team go back to the police dormitory to sleep.

But he ate something by himself and stayed in the office to think about it.

In the blink of an eye, four or five hours passed. Everyone was worried about the case and returned to the office one after another.

Zeng Gaojie and Gao Jinyang were analyzing the places where the four deceased people went before their deaths.

Sister Wang is in contact with Yu Jing.

The latter is responsible for tracking Zhang Ying, but there is currently no progress.

As for Jiang Yang, he sat motionless on his seat like a piece of wood.

Everyone advised him to take a nap first.

But Jiang Yang called them over and said he had made a new discovery.

Upon hearing this, everyone immediately became energetic.

"What did you see?"

Gao Jianmu leaned over and found that Jiang Yang was still studying the scratches in the deceased's bathroom.

"We did suspect that it might be the murder weapon. But except for the bathroom floor tiles, there were no relevant traces anywhere else at the scene."

"Another point is that the deceased's heart was pierced by a sharp object, so the size of the murder weapon should be something that an adult can grasp with both hands."

"The scratches on the ground don't explain the problem."

Jiang Yang didn't say anything. Instead, he pulled out a photo of Tian Xiaoyang's body, pointed at his chest and asked, "The autopsy report stated that the wound of the deceased contained metal particles."

"After physical and chemical treatment, it was determined to be an alloy."

"I have every reason to believe that the scratches on the floor tiles were caused by the murder weapon."

Gao Jianmu frowned and was about to retort when Jiang Yang asked him to look carefully, "There are also pits of different sizes on the skin on the edge of the deceased's chest."

"This is what was left after fighting the murderer..."

"wrong."

Jiang Yang denied Gao Jianmu's view and compared the two photos together.

"Look, the sizes are the same and the arrangement is regular. The murder weapon is not a single stick, it should have other uses. And the surface is uneven, which will leave bumps on the floor tiles and wounds."

After that, he pulled out the autopsy reports of Huang Sheng, Zhuang Fan and Jiang Lei.

"I didn't find any similar traces at the crime scene. Maybe it was too inconspicuous and I didn't notice it at the time. Or maybe it was considered wear and tear on the furniture and I didn't pay attention to it."

Jiang Yang said as he arranged the five photos in chronological order.

At this moment, all the police officers in the office came over.

Especially the criminal policemen in Haicheng City, who were crowded in the crowd with faces filled with anticipation and could only take pictures with their mobile phones.

Being able to discuss the case with Jiang Yang up close was something that many people could only dream of.

"Huang Sheng was dismembered and the cause of death was excessive blood loss."

He clicked on the first photo, which showed six sections of limbs arranged neatly.

Jiang Yang then retrieved the individual body parts from the computer, zoomed in and pointed at one spot and said, "Did you see it? The small pits are uneven."

"Well, this is different from the floor tiles at Tian Xiaoyang's house!"

Gao Jinyang pointed out.

"Yes, but look at the other body parts, every one of them is there."

Jiang Yang said: "Then let's look at Zhuang Fan. His fatal injury is on his neck. Do you think this area is familiar?"

"Damn it! Why are they the same as Tian Xiaoyang's... No, they don't look much alike!"

Gao Jin got stuck halfway through his foreign language.

Jiang Yang smiled and motioned for everyone to see Jiang Lei.

He is the most special one.

Because he was dismembered after death, the cause of death was an overdose of rat poison, which is an anticoagulant drug.

It can cause disorders in the human body's coagulation function, leading to severe bleeding and death.

At that time, the police determined that the murderer first poisoned the deceased's food, and then cut the body into pieces when the deceased became addicted to the poison and called for help.

Unfortunately, the cameras where Jiang Lei lived were not fully installed, so the murderer was not found.

There are three suspects in the case, including Zhang Ying.

They were all contacted by Jiang Lei before his death.

However, when the case was appealed to the Kyoto People's Court last year, it was determined that the evidence was insufficient and did not constitute a condition for prosecution.

And it was found that the other two people had alibis and were cleared of suspicion.

The photo Jiang Yang took out was of Jiang Lei's leg that was thrown into the river.

"There are also pits and marks here."

At this point, all the dead have one more thing in common.

Each part of the body has one or more pits that are not identical.

"Can't it just be an ordinary bump?"

Xiao Zhu raised his hand and asked doubtfully: "The murderer's killing methods are varied. The deceased always has to struggle, right? It's normal to leave some marks during the struggle."

He felt that Jiang Yang was a little too meticulous and unnecessary.

"Then how to explain Jiang Lei?"

Jiang Yang said: "He died first and then was dismembered. He had no ability to resist."

"You might as well think about it, what tools are made of alloy manganese steel and are the right size?"

This question stopped everyone.

"That's a lot! Safes, car engine guards, excavator parts, loader parts... Well, it's a bit big!"

And some parts are illegal for personal possession.

Gao Jinyang was embarrassed and slapped his forehead suddenly, "The knives are also made of manganese steel! Brother Yang, what's so special about this?"

"Yes, it may be related to career."

Jiang Yang pointed to the different seals and said in a deep voice: "Do you know the mold? In some fields, alloy manganese steel will be made into steel seals, and words will be engraved on them."

"Looking at these traces individually, they wouldn't look very strange, but when put together, do they look like patterns or strokes?"

He pulled out more than 20 pictures from the computer, zoomed in on the same part, opened a window, and dragged it to the middle of the screen.

Jiang Yang stood up and made way, and everyone wanted to stick their eyes to the monitor.

"Does it look like words? Why can't I see it?"

Ji Dayu felt like he was going blind.

"It seems a little bit, look at the strokes."

Sister Wang was thoughtful, "But steel stamps are also common! Many heavy machinery stamps use manganese steel molds. But everything used by the company will be registered."

"Yes, and abandoned molds must also be recorded. So our next direction... is to investigate major factories?!"

Zeng Gaojie muttered and took a breath, "Jiang Yang, is the workload a bit too much? I'm afraid we won't be able to finish the investigation after the National Day? There are four crime scenes, and we have to investigate four cities!"

How many factories are needed!

Jiang Yang laughed out loud, "How could that be? Just focus on Haicheng. The murderer must have followed Zhang Ying. She is in Haicheng now, so the other party must be there too."

"Wait a minute, it's also related to Zhang Ying? But are factories recruiting workers so casually? Changing to a different factory or a different city? Brother Yang, I don't understand what you are saying anymore!"

Gao Jinyang held his head and wailed.

Others were in a similar state as him, all of them felt that they understood, but not completely.

Jiang Yang didn't keep the secret and said bluntly: "It's not a factory, it's a more life-like job."

He smiled and whispered: "Goldsmith."

"Ah?!"
