Jiang An shook his head.

"Typically, bodies are placed inside transport bags."

"Additionally, even when transporting bodies, it requires two people cooperating, one at each end."

After pondering for a moment, Wan scratched his head, "However, we didn't see any injuries on this body."

"It can't be that he suddenly died and was abandoned by the roadside, right?"

At this moment, Jiang An focused his gaze back on the torso of the deceased.

For someone so physically robust, how would a killer choose to kill him?

Then, Jiang An slightly squinted his eyes, starting to simulate the crime in his mind.

If he were the killer, how would he do it?

Two minutes later, Jiang An slightly opened his eyes, as if the answer had surfaced in his mind.

Poisoning!

Facing a significant disparity in physical strength, poisoning is the most effective method.

However, during the previous examination, there were no signs of sedatives or organophosphate poisoning characteristics observed.

Immediately, Jiang An's gaze swept over the skin of the body again.

Suddenly, he discovered a small red dot on the left side of the deceased's abdomen.

He hurriedly picked up the magnifying glass beside him and looked down at it.

In an instant, he excitedly turned and said, "I've found it."

"Found what?"

The other three immediately leaned in closely.

"I might have found the reason for the deceased's death."

"What do you mean?"

"I suspect the deceased might have been injected with poison by someone else, leading to death."

"This small red dot should be the needle mark from a syringe."

"Poison injection?"

Zhang Yean and Wan widened their eyes instantly, incredulously.

They had yet to encounter a criminal case of death by poison injection.

However, Li Jian had rich criminal investigation experience.

He immediately thought of cases where people used tranquilizer guns to hunt animals during winter.

Zhang Yean thought for a while and asked, "Even if the deceased was injected with poison, then what kind of poison would it be?"

"Could this poison cause instant death?"

"This person looks very strong; even normal sedatives or other poisons wouldn't cause instant death, right?"

Wan also said, "Junior sister, what you say makes sense."

"The metabolism of any poison needs a process; it absolutely can't cause instant death. Then why didn't the deceased show any signs of resisting?"

The three looked back at Jiang An.

Jiang An nodded.

"That's a very good question."

"However, have you considered that the killer might use a poison that prevents resistance?"

"A poison that prevents resistance?"

"Could it be anesthetics?"

Jiang An shook his head, "Anesthetics indeed can cause unconsciousness, but they are strictly controlled."

After a slight pause, Jiang An said, "Do you think it's possible to be acetylcholine?"

"Acetylcholine?"

Jiang An continued, "It's a muscle relaxant."

"Muscle relaxant?"

Zhang Yean and Wan were full of question marks.

"This drug, once inside the body, won't immediately cause death but will relax muscles, losing activity."

"Thus, our body wouldn't have any ability to resist."

"Would this drug cause death?"

Jiang An replied, "This drug affects respiratory muscles, causing paralysis, losing contraction ability, eventually leading to hypoxia death."

In the conversation, Jiang An turned the deceased's body over, fully exposing the back skin.

He raised his hand and pointed, saying, "The deceased's back is densely packed with livor mortis, deeply colored, which is a significant sign of hypoxia death."

"Therefore, I suspect the true cause of death should be acetylcholine poisoning leading to respiratory failure."

Upon hearing Jiang An's conclusion, the other three once again focused their gaze on the deceased Huang Bing.

After a moment, Jiang An turned around and took out a scalpel and tweezers from the equipment box behind him.

He said, "This is just my speculation."

"I'll extract the muscle near the needle mark for poison testing, and the results will be clear."

Meanwhile, in the criminal investigation team's video surveillance office.

Chen He was leading nine investigators to sift through today's extracted surveillance videos.

The process of extracting surveillance is quite simple, possibly just requiring a large portable hard disk.

However, the analysis of surveillance is very complex.

Besides examining the authenticity of surveillance information, they cannot overlook each frame of the footage, or they might miss critical information.

At this moment.

Everyone was screening the surveillance recording from Wu Yan's storefront.

According to Li Jian's arrangement, they need to conduct an in-depth review of surveillance information spanning a month, focusing on identifying men with high frequency visits.

2:00 AM.

Li Yong arrived at Chen He's office to report: "Mr. Chen, our initial video screening work is completed?"

"How's it going?"

"Through our review of video surveillance, we discovered a middle-aged man with medium build, a slightly large belly, and a round face, who frequently visits the clothing store."

"Two weeks ago, he was coming to the clothing store almost every other day."

"Moreover, each time he went in alone and stayed for more than 30 minutes."

Upon hearing this, Chen He quickly said, "Let's go! Take me to see."

They then went over to the computer screen.

Chen He glanced at it and nodded.

"This man looks like he must be very wealthy, his attire is very particular."

"Is that woman being kept by him?"

"Mr. Chen, it's very possible!"

Li Yong added, "With such frequent visits, if this middle-aged man isn't her relative, then this is very unusual."

Finally, Chen He said, "The image quality is very clear, print it out immediately."

"Anyway, we need to find this person first."

Just as he finished speaking, the door to the video surveillance office was pushed open.

Li Jian, Jiang An, Wan, and Zhang Yean quickly walked in.

Li Jian spoke, "Brothers! Good work, here's some late-night snacks for everyone."

"Thank you! Mr. Li."

"Thank you! Mr. Li."

The police officers in the office rubbed their eyes and turned to gather around.

Li Jian walked over to Chen He and said, "Good work."

Chen He smiled, "Mr. Li, you worked hard too, staying up so late."

"We just came back from the forensic corpse examination center."

Chen He asked, "The corpse examination is already finished?"

Li Jian nodded.

"After a night's corpse examination, we still gained a lot of findings."

"Was the person killed by a traffic accident?"

Li Jian said solemnly, "It was not a traffic accident death, but the body was dumped on the road."

"Jiang An found injection needle marks on the skin, and after testing local skin tissue, acetylcholine was found."

"Acetylcholine?"

Chen He was shocked for a moment, then said, "I know this toxin."

"Last year, I cracked down on a gang of dog thieves who used this toxin to steal dogs."

Li Jian nodded after hearing this.

"Currently, we have confirmed that after Huang Bing died, someone dumped his body on the road."

"The murderer's purpose is to disguise it as a traffic accident death."

Just then, Zhang Yean turned to look at the screen.

Suddenly he exclaimed, "Hey! How did you find the pet store owner's photo?"

As soon as he finished speaking, Chen He quickly turned to ask.

"What? This is the pet store owner's photo."

Zhang Yean looked puzzled, "What's wrong?"

"Today, I went to Xinyuan Pet Shop with Mr. Jiang and met the pet shop owner."

"This is him."

At this point, Jiang An also turned to look and nodded slightly.

Chen He felt a burst of joy in his heart.

"It's like finding something without even looking, it came so easily."

"This time, you really saved me a major effort."

Upon hearing this, Li Jian was confused.

His gaze moved back and forth between Chen He and Zhang Yean.

"What do you mean?"

"Are you two speaking in code?"

Chen He said, "Mr. Li, you don't know!"

"Through the surveillance review, we discovered this man frequently visited Wu Yan's clothing store two weeks ago, and each time stayed for more than half an hour."

Li Jian was taken aback upon hearing this, "He went in alone each time?"

Chen He nodded, "He went in alone each time."

Zhang Yean asked, "In half an hour, was he choosing clothes?"

Chen He shook his head.

"When he entered and left, he was holding a very small handbag and didn't buy any clothes."

"Half an hour, not buying clothes, frequent visits."

These three keywords quickly spun in everyone's minds.

Wan smiled and said, "Could they be having a date?"

After a long pause, Li Jian said seriously, "Go! Bring back the pet shop owner immediately, I think he is very suspicious."
