The Forensic Doctor Better Than a Detective

By the river, three people stared at the hairpin in front of them.

After a long while, Wan spoke up, "This hairpin is quite far from where the box was placed earlier."

"Do you guys think this hairpin is connected to the case?"

"After all, this is an open and spacious environment."

"And occasionally, some people come here for a walk."

After finishing, both Wan and Zhang Yean looked at Jiang An with puzzled expressions.

At this moment, it seemed like Jiang An was their backbone.

Jiang An looked around and once again lowered his head to look at the grassland in front of him.

The hairpin had fallen into the grass but was very close to the pedestrian path nearby.

For a moment, multiple possibilities flashed through Jiang An's mind.

The hairpin might have been left by the victim.

It could also have been dropped by the perpetrator during the body disposal process.

Or, as Wan mentioned, the hairpin might have no connection to the case at all.

It might have been unintentionally dropped by a passerby.

After thinking for a while, Jiang An said, "I think we can take this hairpin back for surface genetic analysis to compare with the victim's DNA and see if there are any genetic components of the victim."

Upon hearing this, Zhang Yean suddenly realized.

Indeed, that's a good method.

If the victim's genetic information can be extracted from it, it could definitively identify the user of the hairpin.

Wan also understood, immediately giving a thumbs up.

"Indeed, high achievers think differently from us average students."

Just when the two were rejoicing, Jiang An continued, "However, the outdoor temperature is very high these days."

"Long exposure to sunlight could significantly interfere with the extraction of genes from the object's surface."

Zhang Yean remained optimistic, "Regardless, we can first take back the hairpin for testing."

Then, Zhang Yean placed the hairpin in the evidence bag beside her.

After doing all this, Wan glanced at the tire marks on the ground and then looked up at the flowing river water.

"Mr. Jiang, now that we've found these two things, is there no need to continue moving forward?"

Jiang An nodded.

"Currently, we can basically confirm that this place is where the body was disposed of."

"Since we've found the body disposal site, the survey work can temporarily end."

A moment later, Jiang An, with a serious expression, said, "However, a question suddenly arose in my mind."

"Why did the perpetrator dispose of the body here?"

Just as he finished speaking, Jiang An's phone rang.

The caller ID showed it was the forensics lab.

"Mr. Jiang, hello, this is Lin Li from the forensics lab."

"Mr Lin, hello."

"The results of the examination on the female lower body evidence you sent over have come out, and no male components were detected."

"None at all?"

Lin Li firmly replied over the phone, "Absolutely none."

"Could it possibly be due to the use of a condom by the male?"

Lin Li replied, "Regarding the transfer swabs extracted from the victim's lower body,"

"We also conducted a chemical component analysis and found no residual chemical components of a condom."

"So, I believe no condom entered her body."

Jiang An nodded after hearing this.

"Received, thank you."

After hanging up, Jiang An said, "No male components were found inside the victim."

"And there's no evidence of condom use."

Hearing this conclusion, Zhang Yean and Wan were instantly stunned.

Wan looked incredulous.

He said, "The victim's lower body was already damaged, could there really be nothing?"

Zhang Yean was also perplexed.

"It does seem odd now."

She speculated, "Could the perpetrator have only committed indecent conduct?"

At this moment, Jiang An didn't speak.

His mind was pondering.

Apart from the possibilities discussed earlier, could there be other possibilities?

A moment later, he said in a deep voice, "Have you considered that the perpetrator might suffer from a condition preventing normal sexual behavior?"

"Or, perhaps the perpetrator was a woman, acting purely out of revenge?"

Upon hearing Jiang An's analysis, Zhang Yean and Wan's eyes widened.

"Mr. Jiang, your thinking is quite broad."

"Junior, what you said makes sense!"

"In the forensic lab, during the partial dissection of the female lower body, I noticed multiple mucosal damages, suggesting significant force and frequency."

Upon hearing this, Zhang Yean lowered her head, her face slightly flushed with embarrassment.

However, she still nodded in agreement.

Then, the three followed the trace of the suitcase wheels in reverse.

Soon, they arrived at the beginning of a cement road.

Wan quickly looked up to search, glancing around, and excitedly said, "Look, there's a high-altitude camera 400 meters ahead."

"I suddenly feel hopeful about solving this case."

"If the perpetrator used a vehicle to dispose of the body, the license plate would be completely captured by the camera."

"Then, finding the suspect through the license plate should be very quick."

Looking along the road, Jiang An nodded.

Then, he took out his phone and dialed Chen He's number.

"Jiang An! What's up?"

"Mr. Chen, have you arrived at the traffic management bureau?"

"Yes! We are at the monitoring control center."

"Please retrieve the footage from the camera on the cement road to the southeast beside the Three Sandstone Plants."
