The Forensic Doctor Better Than a Detective-Chapter 427 - 251: Scratches on the Arm

After a long period, Zhang Yuan slightly furrowed her brows, revealing a hint of urgency in her eyes.

She was the first to break the silence, asking, "So where should we start next?"

As soon as she finished speaking, Li Jian quickly turned, his eyes shining with determination and resolve.

He said, "Here’s my plan for the next steps."

"On one hand, we’ll make breakthroughs through interrogation."

"Since both suspects have been caught, next we need to think about how to make them talk."

As soon as he finished speaking, he sighed.

"However, this might be a bit challenging."

"It seems I have to personally participate in the interrogation to see if I can get their confessions."

"Besides, we also need to focus on investigating all the actions of Li Xiang on the night of the incident."

"Although he swears he didn’t have the time or conditions to commit the crime."

"But that’s just his side of the story."

"We must have our own judgment and not be easily misled by him."

After speaking, he turned fully towards Jiang An, as if anticipating reinforcements.

His gaze was searching and expectant, as if checking to see if Jiang An had any further ideas to add.

As their gazes met, Jiang An instantly understood.

He squinted slightly and remarked slowly, "Mr. Li, I completely agree with your plan!"

"However, I have a small suggestion."

"Go ahead, let’s hear it."

Li Jian quickly turned his head, his eyes fixed intensely on Jiang An.

Jiang An cleared his throat and said in a deep voice, "As a forensic expert, I’ll analyze it from a professional perspective."

"Based on our analysis of the scene, since there was contact between the two."

"Then, according to Locard’s Exchange Principle, as long as there’s contact, there’s material transfer."

"The fibers on the deceased’s watch aren’t from their own clothes, so they must be from the suspect."

After a slight pause, he continued in a deep tone, "Of course, this is merely a possibility."

"There’s also a chance they came into contact with someone else’s clothing in everyday life, leaving traces."

"Therefore, I think this clue should be a key focus for further investigation."

"Regarding the time frame of the crime, Wang Shantao didn’t have time to commit it, but Li Xiang did."

"I believe we should immediately investigate Li Xiang’s house to see if there’s a similar damaged piece of clothing."

Upon hearing this, Wan’s eyes lit up.

He nodded excitedly, "Exactly! Those tiny fiber scratches can easily go unnoticed by the person themselves."

"If we find that piece of clothing at home, it would be strong evidence."

"This could be a breakthrough!"

As soon as he finished speaking, Zhang Yean was as excited as a child, her face full of excitement.

After all, such silent evidence is often the most convincing.

Solving any case relies not only on confessions but more on objective material evidence.

Li Jian’s lips curled up slightly, and he nodded gently, his eyes full of approval.

He smiled and said, "That’s a very good point."

Then, Jiang An, like opening a floodgate, continued, "Actually, I have another clue in this case."

"Another clue?"

"What is it?"

In an instant, the other three were like they had been struck by an Immobilization Spell, faces showing puzzled expressions.

All three of their gazes focused on Jiang An like spotlights.

This very young-looking person always managed to surprise them.

Their hearts filled with both curiosity and anticipation.

Although Zhang Yean was a female, she had long developed a decisive style in the criminal investigation team. Anxious, she grabbed Jiang An’s shoulder, urging, "Hurry up and tell us!"

Jiang An turned his head, a gentle smile on his face, and said, "Actually, what I meant was the trace elements of plants."

"Trace elements of plants?"

"What are they?"

As soon as he spoke, Jiang An lifted his right foot and said, "Look at this."

"The color of this sole is quite normal, isn’t it?"

"If they had an argument there, I believe some trace evidence would be left on the sole."

Upon hearing this, the others nodded, but their eyes were still filled with confusion.

Then, Jiang An explained, "Usually, our shoes stepping on plant stems won’t leave traces."

"However, if there was intense body twisting, the sole might retain the plant’s green sap."

"The incident happened not long ago, so I believe there might be plant stem sap on the suspect’s soles."

"Incredible!"

Wan couldn’t help but exclaim, "Brother Jiang An, you’re amazing. I feel a bit inferior myself."

Li Jian also smiled broadly, feeling very pleased.

He patted Wan on the shoulder, teasingly saying, "Haha, not just you as his senior."

"Even I, as his mentor, feel a bit inferior."

"Haha, Mr. Li, are you his mentor? It seems there hasn’t been any formal mentorship, has there?"

Wan deliberately asked.

"When will the junior set up an event, and maybe we’ll have a formal mentorship, huh?"

Li Jian’s lips twitched; he waved his hand with a smile and said, "No need for that."

"This disciple is so skilled, I feel pressured as a mentor and wouldn’t dare accept."

After the simple interlude, Jiang An had a faint smile on his lips.

He waved his hand and said, "Mr. Li, actually I was just highlighting a potential found at the scene."
