Video surveillance recorded that Mr. Wang had been in a large shopping mall in the northern district of Chongqing eight days earlier, when the temperature in the city was supposed to be high and pedestrians were wearing short sleeves. The surveillance camera was just above the mall's gate, and it clearly captured Wang Xin's figure.

Wang Xin was in a hurry, almost running into the mall, and when he came out, he seemed even more anxious, unlike before, he carried a bag in his hand. Due to the limitations of the surveillance cameras, we couldn't see what he was buying when he went into the mall.

At my urging, Lao Yu showed us the surveillance in the mall again, and finally, Wang Xin appeared on the screen again. With his head down, Wang Xin walked straight into a large pharmacy in the mall, and as he walked, Wang Xin's demeanor indicated that he was worried that others would recognize him.

"Is there any internal monitoring of the prescription?" I asked.

Lao Yu shook his head and replied, "No, we have all transferred back the surveillance records of this mall." ”

We watched the surveillance footage again, and we put the video to the maximum to try to see Wang Xin's expression. On the blurry picture, I could vaguely see Wang Xin's expression at that time: anxious.

I immediately stood up, and I decided to take Jiang Jun to the pharmacy in person. Wang Xin obviously didn't want others to recognize him, but he appeared in such a large shopping mall, as an old criminal policeman, it was impossible for him not to know that there were surveillance cameras in the large shopping mall, so I concluded that Wang Xin had to go to a large shopping mall.

He went to prescriptions, and naturally bought medical supplies, some of which could only be bought in relatively large prescriptions.

The three of us set off immediately, and after more than an hour of traffic jams, we finally arrived in the northern district of Yushi. Standing at the entrance of the large shopping mall, I carefully observed the topography of the mall. After Wang Xin came out, he got into a car, and the license plate number of the car was deliberately blocked.

Later, the car drove to the north outside the mall, where, according to Lao Yu, it would pass a relatively remote house, which was a blind spot for surveillance cameras, and after that, the police could not find the whereabouts of the car.

"Let's go inside." I said to Jiang Jun.

Jiang Jun seemed a little excited, these days, Jiang Jun would call Wang Xin every day, but Wang Xin's mobile phone kept prompting to turn off. Wang Xin's appearance eight days ago means that he was safe at least eight days ago, we have been in Chongqing for several days, and Wang Xin appeared at the mall later than the forensic doctor deduced that the blood stains in the abandoned factory remained, about a day later.

In other words, regardless of whether Wang Xin personally visited the abandoned factory in Guangdong, the blood stains were not fatal. Because after leaving shirts and blood stains in the abandoned factory, Wang Xin appeared in Chongqing again, and according to the footage recorded by the surveillance camera, Wang Xin was not seriously injured.

This made me even more convinced that the shirt and the blood stains were deliberately left in the abandoned factory, and the purpose is unknown.

The sky was overcast and the autumn rain was falling, so we closed our umbrellas and walked into the mall. At three o'clock in the afternoon, the mall was overcrowded, and although the temperature was very low, there was still a hint of stuffiness in the mall. We quickly found the big pharmacy and came here in person, only to know that the pharmacy was much bigger than we expected.

Lao Yu told me that there are no less than dozens of such large pharmacies in the entire city of Chongqing, and many prescription and over-the-counter drugs that cannot be bought in small pharmacies can be bought here. Although Chongqing is carrying out a large-scale reform of the local drug system, it will not be completed overnight.

Therefore, many prescription drugs that are not particularly harmful to the human body can be purchased without providing a certificate from the hospital.

There are many people in the prescription, Lao Yu didn't change into civilian clothes when he came out, and he was wearing police uniforms, which provided us with a lot of convenience. After presenting the certificate, we immediately asked the manager of the prescription to show the purchase record of the medicine purchased by Wang Xin that day.

Soon, the administrator of the pharmacy found a bunch of purchase records for the day. There is no signature on the purchase record, only the time of purchase, so we have no way to immediately find out which record is Wang Xin's. The surveillance screen shows that the time when Wang Xin came out of the pharmacy was 3:28:6 p.m., and there were several customers who came out at that time.

We looked for records from the first 10 minutes of this point in time, but they were all very common medicines and medical supplies such as cold medicines and fever reducers.

"Wang Xin came to the pharmacy just to buy these things?" Lao Yu was a little surprised.

I shook my head: "No way, he was in a hurry, and he tried his best to keep his head down, trying to hide his whereabouts, so he couldn't have come here just to buy some cold medicine." I thought about it, and soon I figured out what was going on. Wang Xin deserves to be a high-level police officer, and his experience is too much.

I don't think he left the pharmacy immediately after he paid the bill at the front desk. He entered the pharmacy for more than half an hour, although he carried such a large bag of medicines, all the medicines in the pharmacy had signs, and it would take more than ten minutes to buy medicines.

In other words, after Wang Xin paid the bill, he deliberately stayed in the prescription for more than ten minutes before coming out. As for the reason for this, it is afraid that someone will find the record of his purchase of medicine based on the time he came out of the pharmacy.

Hearing my analysis, Jiang Jun and Lao Yu both felt that it made sense, so the scope of our search was expanded again. We flipped through the half-hour purchase records one by one, and there were many people buying medicines, and we didn't look aimlessly. Wang Xin bought a lot of medicines and medical supplies, but most people came to prescriptions and would not buy so many medicines.

After some troubleshooting, we found several long records.

We looked carefully one by one, and several of us were not very familiar with the medicines, so we asked the pharmacy management for help. Finally, we settled on a record sheet that showed that the purchaser had purchased a large amount of disinfectant alcohol, gauze, bandages, and very powerful anti-inflammatory and anti-inflammatory drugs.

The management told us that this anti-inflammatory potion and anti-inflammatory drug have a good effect, but they have certain side effects, and they are generally used when they are rescued in the hospital, so they cannot be bought in ordinary small pharmacies.

We asked the pharmacy staff who were on duty that day, and because of the large number of people, they couldn't remember what the people who bought the medicines looked like. Lao Yu used the police investigation of the case as an excuse to detain all the drug purchase records of the day, and after coming out of the mall, Jiang Jun stopped.

"Jiang Jun, don't worry too much, Wang Xin has appeared, which proves that he was safe a few days ago." Old Yu comforted Jiang Jun.

Jiang Jun nodded with a wry smile, he took a deep breath: "I don't understand why he refused to contact me, he is not injured, why did he sneak to the pharmacy to buy medicine." ”

"Obviously, those medicines were not bought by Captain Wang for himself." I analyze.

Jiang Jun and Lao Yu nodded, Jiang Jun carefully recalled that in his impression, although Wang Xin was well-known in the police circles and knew many people in the police circles, his connections had not yet extended to Chongqing, a somewhat special city.

"First of all, it doesn't matter who bought those medicines, it's better to determine Wang Xin's whereabouts first, otherwise Chongqing City is so big, where do we start." Lao Yu felt a little headache, he said that he had not come out to the police for a long time, because he was too old, so he had been dealing with a little civilian work in the police department in the past few years.

When Jiang Jun and I heard this, we looked at each other in unison. I guessed Shen Cheng's thoughts, although he was willing to help me, he only provided me with a small amount of police force, and the person in charge was still an old criminal policeman who was about to retire. Fortunately, he is always enthusiastic and his head is not confused, otherwise there would be great resistance to our investigation.

"There are dozens of such pharmacies in Chongqing, but he chose only this one, so I think my father should be in the northern area of Chongqing." Jiang Jun said.

Lao Yu nodded immediately, he took out his mobile phone, and said that he would immediately send someone to continue the investigation in the north, and I stopped Lao Yu.

"Captain Wang's mind is very delicate, if he deliberately wants to avoid us, I'm afraid he will go around in a big circle." I said.
