Serious Crime Unit 1

Chapter 1072
"Ye Qianqian may be taking birth control pills. If the murderer replaces the last levonorgestrel tablet that Ye Qianqian left at home with a potassium cyanide enteric-coated tablet, Ye Qianqian will take it within 2 to 4 hours after taking it. He will be poisoned and die. This murderer is so powerful, he should have the key to Ye Qianqian's house."

"Yes, after the murderer changed the medicine, the hourly worker came to clean Ye Qianqian's house and wiped away the murderer's shoe prints, so no traces were found at the scene. You can detect the medicine from Ye Qianqian's blood Ingredients?”

"Yes, the components of the drug can be detected using a gas chromatograph, but it takes time."

"Then go and investigate. This is very important for us to carry out investigation work. However, how could the murderer be sure that Ye Qianqian would definitely take levonorgestrel tablets in the early morning of April 4?"

"Ye Qianqian did not have an IUD in her body. If the person she had sex with was unwilling to wear a condom, she would have to take levonorgestrel tablets after the transaction. Because of long-term drinking, Ye Qianqian's stomach wall became inflamed. , she usually does not take levonorgestrel tablets, but levonorgestrel enteric-coated tablets. This Ye Qianqian is also very hardworking. She has gastritis and has to drink desperately. It is really a waste of money and money. Raise people.”

Jiang Yiming has seen the environment around Xuhua's house. Ye Qianqian's bedroom faces the north. Her window is less than one meter away from the house opposite. No one walks in the small alley below the window, and there is a lot of rubbish on the ground that has not been cleaned. If Ye Qianqian Qian Qian threw the packaging box of levonorgestrel tablets under the window, maybe she could still find it.

Jiang Yiming called Zhou Ting, and together they went to look for the packaging box in the small alley under Ye Qianqian's window. Zhou Ting quickly found the packaging box of levonorgestrel tablets and the tin foil wrapping the tablets, and the box left Norgestrel tablets come in one piece, so the murderer only needs to replace it, and Ye Qianqian will die sooner or later.Jiang Yiming had to admit that the murderer was thoughtful.

After they returned to the team, they used multi-band light sources to illuminate the packaging box and packaging tin foil, hoping to extract the suspect's fingerprints. As a result, they extracted two types of fingerprints, one fingerprint was that of a man, and the other was that of a woman. After comparison, the woman's fingerprints belonged to Ye Qianqian.

Then, the other fingerprint should be that of the suspect.Jiang Yiming entered the fingerprints into the computer database for comparison. The result was that there were no matching fingerprints, which meant that the suspect had no criminal record. Otherwise, his fingerprints would definitely be entered into the database of the Public Security Bureau.

"Captain Jiang, I don't think the fingerprint on the packaging box belongs to the suspect. It is most likely that of a pharmacist or pharmacy attendant. Levonorgestrel tablets are not prescription drugs and can be purchased in any pharmacy, but not all pharmacists or attendants wear them. Wear gloves to take medicine to the patient, so the fingerprint is more likely to be that of a pharmacist or waiter," Zhou Ting said.

"Did the murderer wear gloves to buy medicine? If so, would it be suspicious?"

"The murderer is very thoughtful. He will definitely consider the issue of fingerprints. He only needs to apply glue on ten fingers to cover up the fingerprints without wearing gloves at all. Until he sneaked into Ye Qianqian's bedroom to switch levonorgestrel Ketone tablets, he doesn’t need to wear gloves. After the task is completed, he uses alcohol or gasoline to wash off the glue.”

"You make sense, what should we do next?"

"We can find the flow of medicines based on the barcode on levonorgestrel tablets, from which we can find out which pharmaceutical company purchased the goods, and then check from the pharmaceutical company which pharmacy the medicines flow to. This is not something that ordinary people can check, of course. , we are law enforcement agencies and have the right to go to pharmaceutical companies to find out the flow of drugs."

"Great, go check it out." After Zhou Ting walked out of Jiang Yiming's office, Luo Jin came in. He told Jiang Yiming that the ingredients of levonorgestrel tablets in Ye Qianqian's blood had no other pharmaceutical ingredients. This shows that potassium cyanide was wrapped in levonorgestrel tablets by the murderer.

After a while, Zhou Ting walked into Jiang Yiming's office. He said: "Captain Jiang, I used the China Drug Supervision App to find out that the levonorgestrel tablets Ye Qianqian bought were from China Resources Zizhu Pharmaceutical Co., Ltd. to our city's major pharmaceutical companies. For health drug companies, as long as we check the company’s drug flow, we can find out which pharmacy the drugs go to.”

"Without further ado, let's go." Jiang Yiming stood up and walked out, while Zhou Ting went to drive. After they got in the car, they drove towards the Medical Building on Dongfeng Road.After arriving there, they took the elevator directly to the Big Health Pharmaceutical Company on the 14th floor.

The lady at the front desk greeted them. Zhou Tingliang showed her police ID and handed Ye Qianqian the levonorgestrel tablet packaging box that she had thrown away, saying that she wanted to find out its whereabouts.The front desk lady took them to the general manager's office and said that they could only inquire with the permission of their boss.

After knowing their purpose, the general manager seemed very enthusiastic and took them to the director of the management department to inquire.The director opened the company's drug management system and inquired according to the batch number, and found that it was wholesaled to Ping An Pharmacy on February 2021, 2.

Ping An Pharmacy has a total of 18 branches. The main store is at No. 17 Huaxing Road. They went to the main store to inquire.The store manager said that it has been more than three months now. I wonder who the medicine was sold to?
"Don't you have surveillance video in your store?" Zhou Ting asked the store manager.

"Oh, don't mention it. I don't know why recently, our computers are often infected and crashed. Therefore, the monitor often stops running, and the surveillance video taken is intermittent. If you want to see the surveillance video, we can put it in April. I'll give you the copy so far. Because the computer hard drive doesn't have enough capacity, we only save more than a month of surveillance video."

"Okay, turn on the computer and go copy it quickly." Zhou Ting said. The store manager took Zhou Ting to the office, turned on the computer that was working, found the folder of the surveillance video in the D drive, and copied all the surveillance videos to Up the USB drive.After copying, the store manager and Zhou Ting walked out of the office.Jiang Yiming saw that all the waiters in the store were female, and only one pharmacist and the store manager were male. He asked for the fingerprints of the store manager and the pharmacist, and they both agreed.

Jiang Yiming took out the fingerprint collector from his bag and collected their fingerprints. After collecting them, he compared them with the fingerprints left on Ye Qianqian's levonorgestrel tablet packaging box and found that they belonged to the pharmacist. fingerprint.

The pharmacist is 65 years old this year. He used to be a doctor at the Hongqi Town Health Center in Jiangbei District, and is now employed by Ping An Pharmacy.Jiang Yiming felt that it was unlikely that he would have a relationship with a young and beautiful lady like Ye Qianqian. He should have sold the levonorgestrel tablets to the murderer, thus leaving fingerprints on the packaging box.

Jiang Yiming asked him if he remembered who had bought levonorgestrel tablets recently?He shook his head and said: How can I remember this? Hundreds of people come to the store to buy medicine every day.Jiang Yiming told him to think about it carefully, but in the end he still said: I am old and my memory has seriously declined, and I really can’t remember it.

Levonorgestrel tablets are placed in a glass cabinet inside the counter. The drugs in the glass cabinet are generally more expensive or prescription drugs. Most of them are handed over to the patients by pharmacists, but levonorgestrel tablets are Tablets are not prescription drugs, so why are they placed in a glass cabinet?Jiang Yiming asked the pharmacist.

The pharmacist said: Many patients are shy to buy medicine, especially school girls. They often steal levonorgestrel tablets secretly. The store is nearly 500 square meters and there are not enough waiters to keep an eye on every customer. So, they put the often-stolen medicines in glass cabinets.

Jiang Yiming had no choice but to give up and go back to the team with Zhou Ting to think of a way to find the suspect from the surveillance video.

Jiang Yiming handed the USB flash drive to Lu Yingying and said: "Here are the surveillance videos of Ping An Pharmacy for more than a month. The levonorgestrel tablets Ye Qianqian took were sold to the murderer by the pharmacist of this pharmacy. Please lead the surveillance video." Detective team, try to find the suspect."

"Captain Jiang, what are the characteristics of the suspect?"

"I don't know. He should be a man. Of course, he could also be a woman."

"Then how can we find the suspect from the surveillance video?"

"Look who bought levonorgestrel tablets. The monitor is less than 4 meters away from the glass cabinet where levonorgestrel tablets are stored. And the resolution of the surveillance video is very high. You should be able to tell who bought levonorgestrel tablets." Norgestrel tablets.”

Lu Yingying thought for a moment and said, "Okay, I hope our investigation team can find the suspect." Although she said this, she didn't have any confidence because the surveillance video was intermittent. If the suspect was monitoring Levonorgestrel tablets were purchased when the video stopped working, so even if you were blind, you wouldn't be able to spot the suspect.Of course, if the murderer is caught in the future, the surveillance video will be an important piece of evidence.

At this time, Zeng Chenlu called Jiang Yiming and told him: Ye Qianqian once had a close relationship with a person named Ke Daye.But she didn't know what profession Kodano was engaged in, where he was from, and she had never seen him.

After Jiang Yiming hung up Zeng Chenlu's call, he went to find Wen Xiaorou, because she was responsible for searching Ye Qianqian's mobile phone and she should know the situation.

"Xiaorou, is there a person named Ke Daye on Ye Qianqian's cell phone?"

"There are as many as 1110 people in the address book of her mobile phone. I can't remember this person. I'll go look for it." She opened the locked drawer and took out an iPhone 12 phone. After entering the password, she entered the desktop. , enter the three words Kodano in the address book, and the name of Kodano appears in front of you instantly.

"Captain Jiang, there is this person from Kodakye, but we haven't visited him yet."

"Check Ye Qianqian's WeChat address book to see if he is there. If so, look at the contents of his circle of friends."
