Serious Crime Unit 1

Chapter 1243 (2)
Luo Jin asked You Feng to call the cleaning lady for questioning.You Feng then used the walkie-talkie to call a middle-aged woman named Wan Shanhong. She walked to Luo Jin anxiously and asked softly: "Officer, are you looking for me?"

"Yes. Will you be the one cleaning Building 7 on July 19th?"

"Tong Liye and I did the hygiene together." Although her voice was soft, it was crisp and her Mandarin was relatively standard, but her Sichuan accent could still be heard.

"Who cleans the shower room in Building 202?"

"It's me... police officer, what's wrong?"

"Have you ever cleaned the drain cover?"

"No... I'm sorry, I didn't act in accordance with the contract. Please don't tell Manager You. Yesterday, my eldest daughter called me and said that my youngest son had a fever and was hospitalized in the township health center. I have been thinking about my son all day. Due to my illness and poor mental state... I forgot to clean the floor drain." A few tears flowed from her eyes.

"But the floor drain cover is very clean. When was the last time you cleaned the floor drain?" Luo Jin didn't want to blame her. He deeply understood the difficulties of people at the bottom of society.

"It should have been three days ago, that is, noon on July 7."

"Do you often clean the floor drain cover and find hair on it every time?"

"No, I often find that there is no hair on the floor drain cover. Sometimes no hair is found on the floor drain cover for half a month. Therefore, I don't think it is necessary to pry up the floor drain cover and check it every day."

"Thank you, you can go. I won't tell You Feng about this." Luo Jin knew that no matter who he was, he would lose hair as long as he took a bath, ranging from one or two hairs to dozens of hairs. , however, not all the fallen hair is entangled in the floor drain cover. Most of it will be washed away by the water, and a small number will be entangled in the floor drain cover.

"Luo Jin, what are you thinking about?" Jiang Yiming walked up to Luo Jin and interrupted his thoughts.

"I didn't think of anything."

"I have checked the identity of the deceased. Her name is Li Ziya. She is 30 years old. She lives in Anju Community at No. 48 Huaxi Road, Jiangbei District. She is the sales manager of Bai Yueguang Nightclub. She is actually Mommy. She has 120 people under her There are several ladies sitting on the stage, she checked into room 10 at 10:202 last night. Could she have committed suicide?" Jiang Yiming asked.

"It is impossible to commit suicide because there was no murder weapon at the scene. I checked the wound of the deceased. She was stabbed in the heart with a double-edged dagger, causing hemorrhagic shock and died. The murder weapon was taken away by the murderer."

"Have you seen the movie "The Lost Weapon"? The murderer stabbed the heroine to death with an ice knife, and then put hot water to melt the ice dagger..."

"Stop! Stop! No matter how sharp the ice blade is, it cannot be as sharp as a stainless steel dagger. The wounds caused by ice blades and double-edged daggers are different. The wounds caused by ice blades are wrinkled, while the wounds caused by steel daggers are wrinkled. It's smooth, and although the difference is subtle, experienced forensic doctors can still see it with the naked eye." Luo Jin interrupted Jiang Yiming. Although it was rude, it was good for Luo Jin to express his professional knowledge as soon as possible.

"You're great! Since it's not suicide, let's open a case for investigation. What do you think?"

"There are no obvious external injuries on the body, but there are bruises on the upper abdomen that are so light that they are almost invisible. They should be the scars left by the killer when he pressed the deceased in the water and stabbed the dagger into his heart, and the deceased struggled, but the struggle lasted for a long time It will be very short, about 30 seconds to 1 minute; the deceased will still be conscious within 1 minute to 2 minutes, and will lose consciousness after 2 minutes. However, there are exceptions. There are strong people who will not wake up until 4 minutes. He loses consciousness, so after people in movies and TV shows are shot, they will say that their last words are true."

"Can the gender, height and weight of the killer be determined from the bruises?"

"Because the bruise was incomplete and no fingerprints were left, it is impossible to determine the height and weight of the murderer, but the bruise left by the thumb should be that of a man. The murderer is very cunning, even if he left fingerprints on the body, It was also washed clean by the hot springs.”

"When was the approximate time of death of the deceased?"

"From 3:[-] to [-]:[-] this morning, the specific time of death can only be known after an autopsy."

At this time, Lu Yingying and Wen Xiaorou walked up to Jiang Yiming, and Jiang Yiming asked, "Have you found any suspicious people in the surveillance video?"

"Oh, don't mention it. The entire Changfeng Resort's monitoring system has failed for five days. The technician in charge of the operating company is repairing it. According to the technician, the monitoring system was invaded by a very powerful Trojan, causing widespread paralysis." Lu Yingying answer.

"Can you find out the IP address of the hacker?" Jiang Yiming asked. "It's very difficult. It takes a lot of time. If a hacker uses a foreign IP address, even if we find it, we won't be able to arrest the hacker. Team Jiang, let's give up this idea as soon as possible. The murderer can use hackers as accomplices, which shows that he has great power." Big... we should go visit and investigate like we did in the 20s, and surveillance video is not everything."

"With your technology, can you hack the entire monitoring system here?" Although Jiang Yiming is not very knowledgeable about IT technology, he is not proficient in it.

"For Yingying and I, hacking the surveillance system is just a piece of cake. If allowed, we can hack the city's power supply system and keep more than 1000 million citizens in the dark." Wen Xiaorou said proudly. answer.

"It's so scary. Fortunately, you are Bai Ke... It seems that our range of suspects is very wide. We have a tough battle to fight... Yingying, I think you should track the hacker's intrusion path. Don't you have electronic fingerprints?"

"We just obey the order. What if the hacker uses the IP address of this city? Wouldn't it be easy to solve the case?" Lu Yingying answered with a smile. Wen Xiaorou smiled sweetly when she looked at her. Jiang Yiming wanted to give them a scolding, but he couldn't bear it. , so I held back.

Everyone was sitting in a small conference room for a case analysis meeting. Although Luo Jin had already sent the electronic version of the autopsy report to the mobile phones of all team members, he still followed Jiang Yiming's instructions and told everyone the key situations.

"The victim in the July 7 case was named Li Ziya, the mother of Bai Yueguang Nightclub. She died between 20:7 and 20:00 on July 00. The cause of death was that her heart was pierced by a double-edged dagger, causing bleeding. He died of shock. There were about 02 ml of red wine in his body and a large amount of sleeping pills in his blood. It has not yet been determined which kind of sleeping pills it was." Luo Jin said slowly while watching everyone's reactions.

"Sleeping pills? This means that someone gave her sleeping pills before she died. Angkor and I extracted two empty bottles of red wine from the scene. They were Clamiron Double Doll dry red produced in Bordeaux, France. A bottle of this wine costs more than 1000 yuan. "One of the bottles had Li Ziya's fingerprint, and the other empty bottle had a man's fingerprint. I took it to the database to compare, but there was no result. The owner of this fingerprint is very suspected," Xiao Ke said.

"Luo Jin, have any sleeping pills been found in the residue of the wine bottle?" Jiang Yiming asked.

"There are sleeping pills, but we still don't know what kind of sleeping pills it is. It has the same ingredients as the sleeping pills in Li Ziya's body. It can be determined that the sleeping pills were mixed with red wine by the suspect."

"You should be able to drink red wine under sleeping pills, right? Because sleeping pills are bitter when ground into powder, and Li Ziya should drink alcohol frequently. How could she not know that the taste of the wine has changed?" Wen Xiaorou asked.

"Not all sleeping pills are bitter. For example, liquid triazolam has no taste and is often used by gangsters to seduce women. There are also sleeping pills that can be flavored with red wine," Luo Jin answered.

"Old Wu, have you extracted any important evidence?" Jiang Yiming asked.

"We extracted the shoe prints of four men at the scene. After comparison, three of the shoe prints belonged to You Feng and two security guards who had been to the scene. The other shoe print should be that of the suspect. The suspect's height About 176 to 180 centimeters. Because the floor is paved with marble, it is difficult to judge the weight. It should be more than 60 kilograms. The shoe prints of three women were also extracted, namely those of the two cleaning staff and Li Ziya."

"Where are the fingerprints?"

"We extracted 18 types of fingerprints from wardrobes, bedside tables, bed frames, walls, wine glasses and other items. One of the fingerprints was the same as the man's fingerprint on the empty wine bottle, another fingerprint was Li Ziya's, and the other 16 fingerprints I don’t know whose it belongs to.”

"Luo Jin, there should be the suspect's saliva on the wine glass, right? Has anyone found out whose DNA it belongs to?"

"Meng Xia is undergoing testing. When the results are available, he will give the report to me and ask me to compare it with the DNA database. However, I don't have high hopes for this. A murderer who can hire hackers to invade the surveillance system will not It’s easy for us to catch the handle.”

"Well, you're right. Yingying, have you discovered the hacker's intrusion path?"

"No, I said this will take a lot of time. Since it is a hacker, he has the ability to hide his IP address. We will continue to work hard."

"No matter how cunning a fox is, he can't beat a good hunter. Let's do this. Yingying and Xiaorou will continue to search for the hacker's IP address. Lao Wu and Xiaoke will investigate Li Ziya's social background. Zhou Ting and I will investigate the source of the red wine and Interview the staff at Changfeng Resort to see if there are any witnesses." Jiang Yiming arranged the task.

Jiang Yiming and Zhou Ting came to Changfeng Resort. They first approached You Feng and asked, "Manager You, do you know Li Ziya?"

"She looks familiar, but we haven't met each other before. She should have visited our resort before... It's a pity that a great beauty was killed like this. Who has such a big hatred against her? She must be killed." You Fengchang He was a tall man, wearing a suit and tie on a hot summer day, looking as dapper as a jade tree in the wind.It's a pity that his facial features are not very regular, otherwise he would be a standard handsome guy.
