CHAPTER 329: CHAPTER 206: EITHER GENERATED INTERNALLY OR INTRODUCED EXTERNALLY

At this moment, everyone present was deep in thought.

All their minds were pondering the source of the "carbon monoxide."

Especially Mr. Qin, the fire department captain.

With 15 years of experience as a firefighter, he had encountered many cases of carbon monoxide poisoning.

However, in his impression, the season when carbon monoxide poisoning typically occurs is winter.

Carbon monoxide poisoning often results from closed environments or improperly installed water heaters.

Some individuals, even in winter, use coal stoves for warmth, leading to indoor carbon monoxide accumulation and resulting in casualties.

But it’s summer now, not the season for burning coal for warmth.

Looking around, he turned and asked, "Mr. Li, the bedroom is quite far from the kitchen."

"It’s not impossible for carbon monoxide poisoning to occur, but it would take a lot of time."

"As the young officer just mentioned, it’s unlikely to have a home gas water heater running continuously for more than an hour during a shower."

He then turned to look at the fan in the kitchen.

"Moreover, the airflow strength we simulated today is stronger compared to natural wind blowing."

"Under such circumstances, the carbon monoxide concentration in the bedroom still hasn’t reached a lethal level."

"Therefore, I believe the likelihood of carbon monoxide poisoning in the bedroom is not high."

After Mr. Qin’s explanation, Li Jian felt his views were somewhat shaken.

He glanced at Mr. Qin and Jiang, saying, "This room is less than 80 square meters."

"Aside from the gas stove and water heater in the kitchen, I really can’t think of anywhere else that would produce carbon monoxide."

"Indeed, this is a very big issue; in all my years working in firefighting, this is the first time I’ve encountered such a peculiar situation."

Then, he glanced at Li Jian and hesitated, "Mr. Li, I’m not sure if I should say this."

Mr. Li replied, "Mr. Qin, just say whatever it is."

"We are cooperative and friendly units, all in the pursuit of uncovering the truth."

"Is carbon monoxide poisoning really the cause of these two deaths?"

"Given the circumstances of this scene, I don’t think it supports that conclusion of the cause of death."

After pausing for a moment, he continued, "In the hot summer, if someone sleeps in a car with the air conditioning on, it’s possible to die from carbon monoxide poisoning."

"However, the possibility of carbon monoxide poisoning resulting in death indoors is very low."

Upon hearing this, Captain Li Jian glanced at Jiang An.

At this moment, he too was somewhat swayed regarding Jiang An’s certified conclusion of the cause of death.

In the intersecting gaze between Jiang An and Li Jian, he said, "Mr. Li, Mr. Qin, I’m very confident in my analysis of the cause of death."

"Although the initial forensic identification from Jiangcheng Medical University indicated death by alcohol poisoning."

"The high level of carboxyhemoglobin present in the pectoral muscles of the two deceased couldn’t have appeared for no reason; it’s the best indicator of carbon monoxide poisoning."

In conclusion, Jiang An said, "I’m a forensic doctor, I speak for the deceased."

"However, my premise for speaking on behalf of the bodies is to trust the death indicators presented by the bodies."

"For the bodies, carbon monoxide cannot be produced after death."

"On the contrary, as the bodies continue to decompose, the concentration of carbon monoxide internally will gradually decrease."

"Therefore, I believe the internal carbon monoxide concentration in these two bodies was higher when they were fresher."

Listening to Jiang An’s analysis, Captain Qin slightly opened his mouth and licked his lips.

He softly said, "Young man, one often finds themselves out of their depth in another’s field; I’m not in a position to comment on your forensic conclusions."

"However, there’s indeed no source of carbon monoxide found at this scene."

At this point, even Zhang Yean and Wan, who had quietly supported Jiang An, began to glance at him with a hint of doubt in their eyes.

Suddenly, Li Jian’s phone rang, and the caller ID showed Mr. Ma.

"Hello! Mr. Ma."

The call had just been connected when Mr. Ma said with a smile, "Mr. Li, how’s the situation at the front line?"

"Just now, I briefed the family on our latest progress, and they are very pleased with our meticulous work attitude."

"If we find that the source of carbon monoxide is the water heater, I believe this case can be concluded."

Upon hearing this, Li Jian’s gaze froze, and he stood there in a daze.

For a moment, he didn’t know how to respond properly.

Sensing the silence on the phone, the smile on Mr. Ma’s face instantly froze.

Years of working together made him feel that his apprentice must be encountering a problem at the front line.

He then asked in a deep voice, "Li Jian, what’s wrong? Is there an issue with the conclusion?"

Li Jian held up the phone, turned, and glanced at the few people beside him.

Then, he quickly walked into another bedroom.

After entering, he hurriedly closed the door.

On the phone, Li Jian spoke in a deep voice, "Earlier, I reported to you over the phone that we’re conducting an investigative experiment."

"I know, I’m asking now about the outcome of this investigative experiment?"

Mr. Ma urgently asked, "Have you determined the source of the carbon monoxide? We need to give further explanations and communication to the family."

"Mr. Ma, I’m really sorry."

"Through our investigative experiment, we discovered that the gas water heater can indeed produce a small amount of carbon monoxide."

"However, after burning continuously for over an hour, a large amount of carbon monoxide did not accumulate in the deceased’s bedroom."
