Reborn in 1995, Criminal Investigation Records

He listened with trepidation until the very end, only to discover that the two men were merely inquiring about information and nothing more. The heavily pregnant boss almost burst into tears immediately, and from then on, he was extremely cooperative.

According to the other party, the so-called "medicated dog bag" is actually a general term, which is divided into several categories, and basically all small clinics sell them.

Perhaps feeling he hadn't given enough clues, the shopkeeper also told Zhou Yang about a few places nearby that sold this stuff.

"This is really strange!" Fang Duo exclaimed. "In the previous case, Wen Zhanbo was a clinic doctor. How did this case end up being linked to the clinic again?"

"Just because we're connected doesn't mean I'm the killer," Zhou Yang replied with a smile.

Upon arriving at the clinic the owner had told them about, the two casually asked a question, and the owner, without asking any other questions, immediately produced several different types of dog poisoning products.

One type is highly toxic cyanide, whose main components are sodium cyanide or potassium chloride. This type is often called "three-step death" or "cat-killing gas".

Another category is highly toxic organophosphorus pesticides, whose main components are methamidophos, parathion, and carbofuran.

Next came muscle relaxants and the highly toxic rodenticide, tetramine.

Among them, the most common and best-selling are cyanide and pesticides.

Through interviews, it was learned that these items were not only sold at the clinic, but also at hardware stores, labor protection stores, fertilizer stores, and other similar establishments.

However, this did not affect their investigative approach. Their target was someone who knew Zhao Jun and had connections to the Hepingqing City medicinal herb market.

Furthermore, Zhou Yang boldly guessed that this person was most likely a doctor, and that the shop sold such dog poison.

The area, centered around Zhao Jun's courtyard, expands outwards.

This is a last resort. Often, there are only so few clues, and we can only make various guesses around the only one available, hoping to make some progress.

Even if we guess wrong in the end, it won't matter much, because as long as we find out where Zhao Jun bought the poisoned dog, even if the other party is not the introducer, we can still deduce the other party's route.

Could it have been bought in another city?

No! Because of time!

First, Zhao Jun had only been released from prison for a short time. Second, she couldn't have known there were dogs tied up inside the old house before she arrived. It was precisely because of her appearance that the dogs in the yard started barking wildly.

If she had medicine on hand at that time, she would have administered it immediately, and by the time Aunt Liu brought dinner that evening, the dog would probably already be dead.

The only explanation is that after being driven away by the dog's barking, Zhao Jun left, and then returned after Aunt Liu finished feeding the dog, whereupon he poisoned it.

Then, they went to see someone else, or encountered a murderer, and a case occurred.

Therefore, Zhou Yang and Fang Duo are now using the medicine dog bag as a medium to try to pinpoint Zhao Jun's route by tracking time and location, in order to facilitate the search for the murderer.

Since it has already been determined that this case is not a random killing but a premeditated murder, it means that the murderer knew that Zhao Jun was released from prison, or perhaps knew the time when he was imprisoned and went to visit him.

Or perhaps through an introducer?

No, if Zhao Jun were to suddenly encounter the murderer, the murderer wouldn't have had time to make these arrangements, including immediately selecting Li Hanlu as the victim, dismembering her, and then freezing her!

The killer is waiting!

This is the moment he's been waiting for; he's waiting for Zhao Jun to be released from prison!

Then this series of murders began!

"Jinyin Clinic, what a nice name, it must be a female doctor!" The two arrived in front of a clinic, and Fang Duo began to knock on the door.

But there was no movement inside.

"Are you looking for Dr. Ruan?" An old woman passing by stopped and looked the two of them up.

"Yes, what time does she usually open the door?" Zhou Yangchong nodded and asked.

"It's usually open, but something must have happened. It's been closed for two days!" the old woman said, turning and leaving.

Zhou Yang leaned closer and peered through the crack in the door and the window beside it, but found he couldn't see anything. Disappointed, he left and headed to the next place.

......

The two searched for a long time without finding a clinic that matched their description, nor the shop where Zhao Jun bought the poisoned dogs, so they had no choice but to return to the station.

Before leaving, Liu Dake specifically instructed that everyone should return to the bureau for dinner that night, and that the canteen should add more meat.

Green pepper and shredded pork noodles.

The question was about cutting meat into shreds, which was actually almost like shredded meat. However, everyone was clearly not very interested and were focused on eating.

This is also why Liu Chengyu stipulated that everyone must return; things were alright at the bureau, where they could at least get some food.

When investigating cases outside, many people get frustrated and refuse to eat when they can't find any clues, or they simply drink a few sips of water and smoke a few cigarettes to make do.

"Liu Da, the phone!" With a shout, Liu Chengyu quickly put down the box and jogged towards the office.

Before Zhou Yang could react, Wang Chao, Glasses, and the others immediately followed. Zhou Yang hurriedly ate a few more bites, but then realized that everyone had almost left, so he had no choice but to follow as well.

It's so good to be young. I get hungry quickly, eat a lot, and enjoy everything. Unlike before, when my stomach was always bloated and I didn't want to eat anything.

"We found out. Zhao Jun and Li Hanlu both attend Ning'an No. 1 Junior High School. They are classmates!" Liu Chengyu told Zhou Yang, who had arrived late, the message he had just received.

This was when Wang Chao, who was in charge of finding connections between the deceased, asked Zhou Yang after returning and when the various groups were sorting out information: What should we do if we can't find the connections between the deceased in the past few years?

Zhou Yang's answer was, then let's dig deeper, look for those before they entered society, look for high school, junior high school, elementary school, preschool, even whether they were born in the same hospital, dig deep!

In fact, these things are a required course in criminal investigation, but as the saying goes, people are emotional creatures. If they don't get feedback after a long period of hard work, they need encouragement from those around them, even though most of the time the encouragement is just empty words.

Zhou Yang nodded: "Then we can use the process of elimination. On one hand, we'll investigate the school connections, and on the other hand, we'll eliminate other commonalities. Let's hurry and proceed on both fronts simultaneously!"

Xiao Jiale paused. He was still thinking of starting the investigation directly around the other party's classmate relationship, but he didn't expect Zhou Yang to bring up such a point of view. However, this point of view was indeed very correct.

If there is still contact between the other party after their student years, this crucial information will be missed during the campus investigation, resulting in wasted effort or even leading the investigation astray.

"Okay, those who aren't full, go to the restaurant later and ask Old Tang for two eggs and steamed buns. Next, we'll get to the focus of our investigation..." Liu Chengyu finished speaking and looked at everyone, his meaning clear: did anyone have anything to add?

"Master... Master Liu!" Zhou Yang hesitated, as if he wanted to say something but then stopped.

"If you have a different opinion, just say so. Stop babbling. We're investigating a case right now, so don't hold back!" Liu Chengyu put the cigarette pack he had taken out back into his pocket and looked at Zhou Yang.

"I want to go back to the plaza of the Xiangjiang Hotel and keep watch for a bit more..."

"They said there weren't many clues left in that place, so you go look for it..." Liu Chengyu's voice trembled halfway through his sentence. Zhou Yang had just mentioned staking out the place.

Could it be?

Zhou Yang nodded: "I'm afraid the killer will commit another crime and dispose of the body!"
