The Forensic Doctor Better Than a Detective Chapter 138 - 130: Special Oil Components

Zhang Yean fell into her mories.

She said sowhat guiltily, "If this tal canister was moved after the scene investigation, why didn’t we discover the dagger then?"

"Moreover, I rember the scene investigation was very thorough at that ti."

Jiang An picked up a piece of broken brick with a hole in it before him.

He said, "Because this is a hollow brick, I highly suspect the dagger just happened to fall into the hole of the hollow brick."

Wan stood up and ca over with a complete hollow brick to compare.

"It is indeed as Jiang An said; the dagger can fit perfectly into the hollow space."

Li Jian looked at it and nodded.

"Zhang Yean, don’t bla yourself."

"If it was a pile of hollow bricks then, probably no one would have thought of this possibility."

Then, he said, "Zhang Yean, observe carefully later for any fingerprint marks on the dagger handle."

Zhang Yean quickly responded, "Mr. Li, okay!"

Wan, looking curious, asked, "Junior, how did you know this tal canister was moved?"

Jiang An raised his hand to point to the right.

"There is a very slight arc-shaped indentation here, so I deduced that the tal canister had been moved."

Wan looked down and instantly gave a thumbs up.

"Junior, impressive! Your eyes are sharp."

Chen He patted Jiang An on the shoulder.

"If there really are fingerprints on it, I think we could apply for another third-class personal rit for Jiang An."

Jiang An grinned and said, "Mr. Chen, solving the case is more important than earning credits."

Chen He shrugged.

"You young people have started to treat money like dirt?"

"Honor isn’t important, but the bonus is quite generous."

Wan also looked envious, "Junior, you’re really a bit of a show-off."

Suddenly, Jiang An’s peripheral vision unintentionally caught sight of the dagger’s handle.

Besides seeing the red brick residue, he also noticed a slightly greasy appearance.

Finding the murder weapon made all five feel extrely pleased.

For the investigation, this was definitely a leap forward in solving the case.

If Zhang Yean could find the suspect’s fingerprints on this murder weapon, input them into the database for comparison, and identify the suspect,

then, this case could be declared solved imdiately.

Subsequently, the five packed up their tools and left the construction site.

After a short rest at the municipal office, Li Jian said, "Mr. Chen, please go and verify if Wu Juan has had any venereal diseases."

Chen He nodded but looked a little embarrassed.

"Mr. Li, it’s not appropriate for a man like to ask her directly, is it?"

"Sounds quite reasonable."

Then, Li Jian turned and said, "Zhang Yean, accompany Mr. Chen there."

Zhang Yean nodded, lifting the evidence bag in her hand.

"Mr. Chen, give 10 minutes to put this dagger in the fingerprint fuming chamber."

"Alright! I’ll wait for you in the garage on the first floor."

Li Jian added, "You can also check her dical records at major hospitals. Now that there’s an electronic system, it’s convenient to search."

"We could even have her get tested."

Chen He asked, "If the disease has healed, wouldn’t it be undetectable?"

Wan suddenly interjected, "Is it possible to detect it?"

"I rember if soone contracts syphilis, they’ll be marked as a syphilis patient for life."

"Because in a blood test, there will be a positive syphilis antibody."

Zhang Yean looked incredulously at Wan, eyes wide.

"Senior, how are you so familiar if you haven’t studied dicine?"

Wan looked around, suddenly noticing everyone’s eyes focused on him.

He quickly waved his hands, saying, "Haha, I just love learning, read extensively, and know so dical knowledge."

Li Jian jokingly said, "Next ti the unit organizes a health check, I’ll specifically tick a syphilis antibody test for you."

Wan patted his chest, "Captain, I’m not worried, I’m clean!"

After a small episode, Chen He and Zhang Yean left the office.

Wan slumped in the chair, took a sip of water, and said, "Mr. Li, can our team take a short break now?"

Li Jian shook his head, saying, "We’re hitting the road imdiately."

"Hitting the road? To where?"

"To the provincial city for a lipid composition analysis."

"Yesterday, I learned a friend in the analysis institute there can conduct lipid composition analysis."

"We’ll take the rebar from the cri scene over there for testing right away."

Wan looked helpless, lifting his teacup to take a couple of sips.

"Brother, I’ve been grinding continuously for a week."

"Even a working donkey isn’t used like this."

Li Jian ca over, patting his shoulder.

"Young man, show so initiative; the future is yours."

After saying that, Li Jian turned to look at Jiang An.

"Jiang An, would you like to co with us?"

Jiang An thought about it, having no other pressing matters at hand.

He said, "Mr. Li, I’ll go with you."

Subsequently, the three of them took the rebar and set off in the car.

3:00 p.m.

Li Jian, Wan, and Jiang An arrived at the Provincial City Special Substances Identification Center.

As soon as the police car parked at the entrance, they saw a middle-aged man with glasses walking up.

"Mr. Li! Long ti no see."

Li Jian just got out of the car when the man greeted him warmly.

The two shook hands firmly.

Li Jian said, "Mr. Wang, long ti no see, I’ve missed you."

"Let introduce, they are two mbers of the Jiangcheng Criminal Investigation Team."

"This is Wan Junjie."

"This is Jiang An."
