With these questions in mind, Jiang An picked up the Willow Leaf Blade and came to the right side of the deceased's head.

Immediately, his gaze settled on the spindle-shaped wound on the scalp.

The edges of the wound were irregular, with small jagged skin lacerations visible in places.

After observing for a long while, Jiang An turned his head and asked, "Mr. Zhao, do you know how the initial forensic examination deduced the tool for this injury?"

Mr. Zhao recalled and said in a deep voice, "I remember that at the time, based on the shape of the wound, they deduced it was caused by a blunt strip-like object."

"Did they specify which kind of tool?"

Mr. Zhao shook his head, "No, they didn't!"

"I remember that their tool deduction could only analyze whether the tool was blunt or sharp, not pinpoint a specific type of tool."

Jiang An nodded upon hearing this and observed the scalp wound again.

Two minutes later, Li Hongbing leaned in.

"Brother Jiang An, share your insights?"

Jiang An turned his head and said, "I wouldn't call it an insight, just a personal opinion."

"Please go ahead."

"The characteristics of the wound on the right side of the deceased's scalp are very obvious. At the forensic deduction analysis level, it should be of the blunt instrument type."

"After all, if it were a cleaver, dagger, or other sharp weapon strike, the edges of the scalp wound would be quite neat."

After pausing for a moment, Jiang An said in a deep voice, "However, deducing the specific murder weapon is not impossible."

"Oh?"

Li Hongbing suddenly perked up, looking very surprised.

It's worth noting that the murder weapon used against the female victim has always been a key focus of the investigative team.

Initially, the forensic deduction was merely a blunt object, which was too broad and imprecise for targeted searching.

For a time, investigators even thought the murder weapon had been taken away by the perpetrator.

If Jiang An could conduct an in-depth analysis of this striking tool, it would surely offer more clues to find the murder weapon.

Thinking of this, Li Hongbing felt a wave of excitement.

He hurriedly asked, "Mr. Jiang, what type of tool do you think it is?"

Jiang An glanced at the scalp wound and said seriously, "This wound has slight tearing at the edges, but the corresponding part of the skull is a linear fracture."

"The severity of this linear fracture is much less than that of a comminuted fracture."

"In my forensic career, I believe that a metal object striking the head often causes localized comminuted skull fractures."

"A wooden object strike often results in linear skull fractures."

As soon as he finished, Zhang Yean curiously said, "Mr. Jiang, are you saying this wound was caused by a wooden stick?"

Jiang An nodded and explained, "Judging by the material of the murder weapon, I think it should be made of wood."

"However, I think this tool is not cylindrical but square in shape."

"Square?"

Instantly, everyone fell into deep thought.

A square cross-section and elongated shape.

What could this tool be?

Just then, Li Hongbing's phone rang.

He took out his phone and glanced at it. The caller ID read "Mr. Ma!"

"Mr. Ma!"

"Old friend, did Jiang An and his team help you solve the case?"

Li Hongbing looked up at Jiang An.

He smirked slightly, "Yes, they did! And their help was significant!"

"Haha! Really?"

"Mr. Jiang just came today, and simply listened to the case briefing before pinpointing the crux of the issue."

"Moreover, his points are well-founded and convincing to us all."

"That's great to hear! That's great!"

On the other end of the line, Mr. Ma's face beamed with a proud smile.

If Jiang An could perform similarly well in Han City, achieving great success, it would bring Mr. Ma pride too.

At future annual public security commissioner meetings of Dragon Country, he could proudly speak of it.

Furthermore, if Jiang An truly helped his old friend Li Hongbing catch the culprit, wouldn't the old friend owe him a favor too?

This was truly killing two birds with one stone.

Thinking of this, Mr. Ma quietly said, "Han City is full of criminal investigation talents. Jiang An is there to assist with the case and also to learn."

"Old friend, be generous and teach the young ones."

Li Hongbing said, "Mr. Ma, I do enjoy teaching others."

"But, alas, my abilities are limited!"

"However, rest assured, Mr. Ma, since we personally invited this criminal investigation expert, we will be sure to host him graciously and not neglect him."

After hanging up the phone, Li Hongbing said, "Just now, Mr. Ma called and expressed concern for you three."

Wan smiled and asked, "Mr. Li, did he mention anything about giving us time off to rest?"

"Time off?"

Li Hongbing's eyes widened in surprise.

Wan quickly waved his hand, "Forget it if he didn't!"

At this moment.

The entire scene of the original death site appeared in Jiang An's mind.

He believed that the murder weapon used by the perpetrator was likely still at the scene.

After a long while, Jiang An said, "From analyzing the shape of the wound, I highly suspect the murder weapon used was a stool."

"A stool?"

Mr. Zhao murmured to himself.

His mind was busy recalling.

Indeed, there was a wooden stool in the bedroom.

But during the on-site investigation, no special attention was given to it.

They never realized that the stool was the murder weapon.

The image of that wooden stool also flashed through Li Hongbing's mind.

After contemplating for a minute, Li Hongbing said, "Mr. Jiang, I remember there was no bloodstain found on the legs of the stool in the deceased's bedroom."

Jiang An replied, "Although the structural tension of the scalp is strong, its blood vessels are not very abundant, and the hair content of this female victim was quite substantial."
