CHAPTER 325: CHAPTER 204: EXPLORING A POSSIBILITY!

Zhang Yean pondered for a moment and said in a deep voice, "It’s not winter now, so it’s impossible for someone to use charcoal for heating."

"If it really is carbon monoxide poisoning, then the source is quite strange."

Jiang An lowered his head and scanned the corpse once more.

"Currently, I’m only suspecting that the deceased might have died from carbon monoxide poisoning based on the color of the livor mortis. The specific results will still depend on laboratory tests."

However, Li Jian’s face was very serious at the moment.

Although Jiang An spoke conservatively just now, it was a modest statement.

Based on his understanding of Jiang An, if he’s not at least 90% sure, he usually won’t voice his opinion.

But!

Where did the carbon monoxide come from?

Just as Li Jian was puzzled, Jiang An opened the toolbox and picked up a scalpel and tweezers.

Seeing Jiang An’s actions, Zhang Yean was a bit surprised.

Then, she asked, "Junior, are you going to dissect them further?"

Jiang An shook his head, focusing his gaze on the deceased’s chest.

"The body has already been systematically autopsied, and almost all the blood has been lost. It’s impossible to extract and test for the carbon monoxide concentration in the blood."

"If we want to determine whether the deceased died from carbon monoxide poisoning, we can use the pectoralis major muscle as a test sample."

"The pectoralis major muscle?"

Upon hearing this, Wan raised his hand and touched his own chest.

"This is the first time I’ve heard that muscle can be used to detect carbon monoxide concentration."

Jiang An held the scalpel in his right hand, tweezers in his left, and approached the female deceased.

He lifted the willow leaf blade and inserted it vertically into the right side of the deceased’s chest, sliding it gently to form an arc on the chest.

Then, Jiang An took the tweezers, pulled the skin at the incision, maintaining tension, and slid the willow leaf blade under the skin on the chest, separating the muscle from the skin.

After 1 minute, a piece of red pectoralis major muscle was separated and cut out.

"Wan, please bring a white evidence bag over."

"Alright! Hold on a moment."

As Jiang An placed the muscle held by the tweezers into the evidence bag, Wan smiled and said, "Wow! Your scalpel skills are impressive!"

"Quick! Precise! Ruthless!"

Jiang An said in a deep voice, "The specialty of a criminal detective is to use a gun, the specialty of a forensic pathologist is to use a knife!"

Wan gave a thumbs-up in admiration, "Impressive!"

Immediately after, Jiang An used the same method to take the pectoralis major muscle from the male deceased.

After completing all this, he turned and said, "Mr. Li, the examination of the two corpses has been completed."

At this moment, Li Jian’s thoughts were pulled back to reality.

"Huh?"

"So quick!"

Jiang An nodded, "I’ve already extracted the samples for carbon monoxide testing."

"Whether they died from carbon monoxide poisoning will depend entirely on the final test results."

Captain Li Jian glanced at the evidence bag Wan was holding and nodded slightly.

After a brief pause, he asked, "Is there no damage to the skin surface of these two deceased?"

Jiang An shook his head, "I just re-examined the entire skin of both deceased, and indeed, there were no outward injuries."

Long after, Li Jian said, "Since your examination is finished, let’s immediately take the pectoralis major to the lab for testing."

minutes later, the group returned to Jiangcheng City Bureau’s criminal investigation team.

Li Jian said, "Wan, immediately take these two muscle samples to the toxicology testing lab. I’ll call them to expedite the examination."

"Okay! I’ll take them over right away."

"After you drop them off, come straight to the cafeteria; we’ll wait for you there."

Subsequently, Li Jian, Jiang An, and Zhang Yean turned and walked towards the city bureau’s cafeteria.

Just as they reached the entrance of the cafeteria, the three happened to meet Mr. Ma.

"Mr. Ma!"

"Mr. Ma!"

"Mr. Ma!"

Seeing Jiang An, Mr. Ma smiled faintly.

"Take a look at the 7.24 case when you have time."

As soon as he finished speaking, Li Jian hurriedly said, "Mr. Ma, Jiang An has already carefully reviewed it. We just returned from the forensic autopsy center."

Suddenly, Mr. Ma froze.

"Back from the forensic autopsy center?"

"Has there been another homicide?"

Li Jian said, "Reporting to Mr. Ma, our purpose for going to the forensic examination center was to re-examine the bodies from the 7.24 case."

"Wasn’t that body thoroughly autopsied by the professor?"

Mr. Ma asked curiously, "Is there still an issue with the body?"

As soon as he finished speaking, Li Jian gently nodded.

"Mr. Ma, regarding the determination of the cause of death, Jiang An does not agree with the conclusion of the forensic identification center at Jiangcheng University of Medicine."

In an instant, the causes of death for the two bodies flashed in Mr. Ma’s mind.

"Wasn’t it alcohol poisoning?"

Li Jian turned to look at Jiang An, indicating that Jiang An should answer.

"Mr. Ma, by observing the livor mortis on the two bodies, I noticed the color was somewhat red, suggesting the possibility of death by carbon monoxide poisoning."

"Death by carbon monoxide poisoning?"

Jiang An nodded, "Samples have already been extracted from the deceased, awaiting the next stage of testing."

A moment later, Mr. Ma’s face turned serious.

"This issue is very critical, you must find out and clarify!"

"You must thoroughly investigate the exact cause of death."

"Yes!"

Li Jian, Jiang An, and Zhang Yean responded in unison.

Subsequently, Mr. Ma entered the cafeteria.

The next second, Wan came jogging over.

"Why are you guys walking so slow?"

Zhang Yean said, "We just happened to run into Mr. Ma!"

"Mr. Ma? For what?"

"He wants the cause of death clarified and the nature of the death confirmed."

Wan turned to look at Li Jian and Jiang An, noticing the solemn expressions on their faces.

He immediately understood.

During the entire lunch, the four of them ate separately without chatting.
