CHAPTER 314: CHAPTER 198: JIANG AN’S TRUMP CARD

After Jiang An’s analysis, the others became more confused the more they listened.

Suddenly, Zhang Feng said, "Brother Jiang An, you’ve said a lot."

"I still don’t understand. In the course of contact between the murderer and the deceased, could it be that their struggle caused a great violent pull leading to fractures?"

"Furthermore, I didn’t see any marks of a beating on the deceased."

"At least in my view, the degree of resistance wasn’t that high."

Jiang An listened and gently nodded.

"Mr. Zhang, what you said does indeed make sense."

"We didn’t find many combat-related injuries on this body."

"However, just as I mentioned earlier."

"During the process of transporting the deceased upstairs to dump the body, it had to pass the gravel ground on the first floor."

"In my initial analysis of this case, I mentioned that the suspect might have slipped while passing there."

"And it’s due to this sliding behavior that the deceased sustained abrasions on their forehead."

After a brief pause, Jiang An said, "In retrospect, I feel my earlier consideration was incomplete."

"The murderer might have also gotten injured during this fall."

Instantly, everyone began thinking in this direction.

"What do you mean?"

"Is this avulsion fracture formed during the process of moving the body?"

Jiang An said in a deep voice, "I believe this possibility is significant."

"No matter how mature someone’s criminal psychology is."

"During the stage of creating a fake crime scene after the murder, there’s invariably some degree of tension."

"Moreover, we indeed found clear heel skid marks on the gravel ground."

"During the transportation of the body, the suspect and the deceased were interconnected."

"When the deceased fell to the ground, the other person couldn’t escape either."

"Thus, considering the whole situation, I believe the suspect had noticeable falling behavior."

"Furthermore, when we suddenly fall, the body instinctively takes self-protective actions."

"And during this process, instinctive self-protection often involves intense muscle contractions, leading to muscle pulling and fractures at the joint areas."

After thinking for a while, Mr. Zhang said solemnly, "Brother Jiang An, I think what you said makes a lot of sense."

Then he turned his tone and said in a deep voice, "However, these are all subjective analyses."

"Without objective evidence to support them, the strength of breakthroughs in interrogation won’t be substantial."

After hearing this, Jiang An also fell into thought.

Suddenly, he had a bold speculation.

He said, "In all the avulsion fracture cases I have encountered, they were basically formed during falls."

"And during a fall, limbs would inevitably come into contact with the ground."

"Therefore, I believe that in this case, the suspect’s arms might also have injuries."

"Will the injuries still be visible two months after?"

Zhang An answered solemnly, "Injuries are very likely to heal after two months."

"But after healing, the color can still differ, usually showing pigment reduction."

"Let me go to the interrogation room and take a look."

After hearing this, Mr. Zhang still had a heavy expression on his face.

Just like the ancient saying goes, treating a dying horse as if it’s alive.

As long as they can find objective evidence of the crime, they won’t give up.

Subsequently, Mr. Zhang said, "Brother Jiang An, I’ll entrust this matter to you."

Jiang An nodded.

He resolutely turned and walked towards the interrogation room.

Mr. He followed along.

Zhang Yan looked up and glanced.

She noticed a young unfamiliar face entering.

"Officer, don’t waste your time," she said.

"I also hope you can catch the murderer and bring peace to us."

"But don’t get your direction wrong."

Jiang An didn’t respond to her and walked straight over.

"Please straighten your arm, expose your palm, so we can take a closer look."

"Looking at the skin on the hand?"

Zhang Yan twitched her lips.

"Wow! Are the police investigating cases by reading palms now?"

"Even if you invite a mage, I won’t admit."

Mr. He flashed a trace of anger on his face.

"Be honest, don’t ramble on," he said.

At this time, Jiang An lowered his head to observe.

He compared and observed from both sides, not missing any inch of skin on the palm.

Jiang An examined very carefully, with the palm’s texture fully displayed in his view.

In Jiang An’s view, if there was a falling behavior that led to hand injuries at that time.

Then after local skin injuries form scabs and fall off, there will be pigment reduction."

After carefully examining the back of the hand, he then said, "Please turn it over, I want to see the back of the hand."

Two minutes later, Jiang An’s gaze stopped.

In the location between the second and third knuckles of Zhang Yan’s right hand, there was a certain pigment change.

Mr. He stood aside, sensing something unusual.

He walked over and asked solemnly, "Brother Jiang An, have you found anything?"

Jiang An turned his head and said, "Mr. He, can you find a magnifying glass for me?"

"A magnifying glass?"

After a moment of surprise, Mr. He immediately said, "No problem! I’ll go to the office to get one for you right away."

Five minutes later, a magnifying glass was brought.

Jiang An took the magnifying glass and placed it on the skin area with pigment change.

After local enlargement of the skin, Jiang An observed more clearly.

Earlier, he still had some doubts in his mind.

But now he confirmed that these positions had skin damage.

After the scabs fell off, they formed pigmented changes.

Then, Jiang An asked, "When did the skin damage in this area form?"

The woman lowered her head and glanced, with a trace of panic flashing in her eyes.

"There wasn’t any injury!"

"This looks so normal."

Jiang An said in a deep voice, "Please no longer cover it up."

"I’m a forensic expert, I know your body structure better than yourself."

Then he raised his hand to point, "The pigment lightening in this area indicates there was once an external skin injury here."

Upon hearing this, Zhang Yan quickly defended, "I don’t understand what you’re saying."

"I know my body."

"I wasn’t injured!"

Just as she finished speaking, Jiang An said in a deep voice, "I can issue a report on skin damage identification based on the skin color change."

"With white paper and black ink, and the seal of the identification institution."

"Do you think the judge will believe your defense or my identification document?"

In an instant, Zhang Yan froze there, staring straight at Jiang An.

Jiang An continued, "I not only know this position was injured."

"Moreover, I also know, at the instant your hand was injured, the intense pull caused an avulsion fracture in the right hand elbow."

"Earlier, I didn’t see any skin damage at the right elbow."

"Thus, your elbow fracture was not a direct local impact but was formed by indirect force, also known as conductive violence in forensic mechanics."

After a long time, Zhang Yan tilted her head and said, "Even if you analyzed it correctly, what then?"

"Walking entails stumbling as well, it’s not strange to fall and fracture."

After a moment of silence, Jiang An said, "It’s not strange to fall while walking."

"What is strange is when did you fall?"

"Where did you fall?"

"Why did you fall?"

After three rhetorical questions, Jiang An continued, "During a normal person’s fall, both hands instinctively extend to protect themselves."

"In such a case, the injured position on the hand would be the palm."

"However, the injured part of your hand is the back of the hand."

"This clearly indicates that during the fall, your right hand did not extend out to protect the body."

"From a forensic deduction standpoint, there are two possibilities for this occurrence."

"One possibility is that you lost consciousness, fell to the ground without awareness, and couldn’t protect yourself."

"The other possibility is that you were holding onto something heavy and didn’t manage to instinctively react to protect yourself."

Instantly, the atmosphere in the interrogation room dropped below freezing point.

Zhang Yan stared wide-eyed at Jiang An, her hands tightly clenched together.
