Serious Crime Unit 1

Chapter 195 Alliance Showdown (7)
"The problem is that Li Ren wears a condom when he has sex with others. I extracted a lot of lubricant ingredients from his genitals. It is the kind of lubricant commonly used in condoms. This is very abnormal. Think about it, Li Ren Ren knew that he was going to die, and it didn’t matter even if he contracted AIDS, so why bother?”

"Oh? What if the woman asks Li Ren to wear a condom?"

"But we didn't find the condom packaging in Li Ren's car or next to the car. It was obviously taken away deliberately. So why did she or he have to take away the packaging?"

"Luo Jin, you're right! Why don't they have sex in the spacious bedroom of the wooden house, but go to the narrow cab? This doesn't make sense, Luo Jin, good on you." Jiang Yiming said to Luo Jin Thumb.

Jiang Yiming called everyone to a meeting to express his and Luo Jin's thoughts. Everyone felt that Li Ren's death was questionable.

Wu Jiang said: "Yes, I picked up a woman's fresh shoe print at the scene. I thought it might have been left by other passengers. After all, it was a parking lot; also, I picked up a woman's fingerprint in Li Ren's car. If Li Ren committed suicide, so this woman has a lot to do with the case."

"Old Wu, could this woman be the woman who took Luo Liangcai's car back to the Yangtze River?" Lu Yingying said.

"Isn't it possible? Are your thoughts jumping too fast? The mysterious woman in Luo Liangcai's car is Li Ren's accomplice. How could she kill Li Ren?"

"It's a pity that Luo Liangcai's shoe prints and fingerprints were not found in her car, otherwise we could have compared them, and the results would have been clear once they were compared."

Jiang Yiming said: "This case is getting more and more complicated. The suspect was actually murdered. Is it a mantis stalking the cicada? We must file a case for Li Ren's death. Zhou Ting and I will continue to follow up on Luo Liangcai's case. Wu, Xiao Ke, and Lu Yingying are investigating the Li Ren case. Let’s name it the 9 case. Yingying, is there any news about the mysterious woman in the 20 case (Luo Liangcai case)?”

"No, although I published her photos online and rewarded citizens who provided valuable clues, nothing happened. Maybe her makeup skills were too good, and no one recognized her after taking off her makeup."

Li Ren's death by homicide is just speculation and there is no evidence to support it, but this inference is logical.After the meeting, Wu Jiang and Xiao Ke went to the evidence warehouse, drove Li Ren's car out, parked it next to the basketball court, and carefully observed the outside of the car.

This modern car has two exhaust pipes. Wu Jiang suddenly discovered that there was something strange about them. One exhaust pipe was full of smoke and dust; the smoke in the other exhaust pipe seemed to have been wiped with something. Wu Jiang was doing a trace inspection. He is most sensitive to this, but he is not very knowledgeable about cars, but he knows that for any car with two exhaust pipes, the thickness and dirtiness of the exhaust pipes should be the same, or at least very similar.

Luo Jin said that Li Ren died of carbon monoxide poisoning. Carbon monoxide is emitted through the exhaust pipe. It is easier for carbon monoxide to enter the car in a closed garage, but in an open parking lot, it is not easy for carbon monoxide to enter the car because of the wind. Is there a way to make carbon monoxide enter the car faster and easier, causing Li Ren's death?
Xiao Ke used to be a racing driver in the police academy. He once won the No. 1 racing car held by the police academy. He is a car fan and knows all kinds of cars very well. Wu Jiang told Xiao Ke his thoughts, and Xiao Ke suddenly became alert. He thought for a while and said: "If someone inserts a plastic pipe into the exhaust pipe and then puts the other end of the plastic pipe into the trunk, carbon monoxide can enter the car faster and thicker, which will quickly lead to Li Ren's death."

Wu Jiang understood what was going on. If Xiaoke's statement was confirmed, then Li Ren's death was an outright murder!

They extracted the smoke around the exhaust pipe and took it to the laboratory for testing. They found trace amounts of plastic particles. This confirmed that after Li Ren fell asleep drunk, someone started the motor with the car key and kept the car idling. , then closed the car door tightly and used a plastic pipe to discharge the exhaust gas into the trunk, allowing Li Ren to die without feeling anything.

Who murdered Li Ren?

Li Ren's wallet did not contain a hundred-yuan and a 50-yuan bill, but only three ten-yuan and two five-yuan bills. So, Li Ren should have given all the money to the mysterious woman who had sex with him, or the mysterious woman might have met Li Ren. After falling asleep, he took away all Li Ren's money, but there was no woman's fingerprint on Li Ren's wallet. Unless she wore gloves to withdraw the money, this woman should be a nightclub or hair salon girl, otherwise she would not have seen Li Ren intoxicated. He took all his money.

Could the mysterious woman be the murderer?

The shoe prints extracted from the scene of Li Ren's death were many and messy, but only the mysterious woman's shoe print and a man's shoe print were fresh, and the other was Li Ren's shoe print.The unknown man's shoe prints may be those of the murderer, or they may be left by tourists that morning.This shoe print is of Nike sneakers, size 42. It is estimated that he is about 1.78 meters tall. If he was a tourist, it would be difficult for him to find that Li Ren died in the car, because the front of Li Ren's car was facing the mountain, and all four doors were blue glass.

Of course, the first step is to find the mysterious woman.

Wu Jiang and Xiao Ke came to Pinghu Resort, found the security manager, and asked to see the video of the evening of September 9. The manager said that except for the lobby and floors of the reception center, there were no monitors installed in other wooden houses.

"Are there surveillance cameras in the parking lot?"

"It was installed before, but the heavy rain on the 15th last month destroyed the monitor. I called someone to repair it, but they haven't come yet." The manager said uneasily.

They called up the surveillance video in the lobby of the reception center and slowly checked it. At 6:02 that evening, Li Ren walked into the lobby relaxedly and happily, took out his ID card, smiled and talked to the check-in waiter. He didn't look like he was about to check in at all. There was no one else around Li Ren, who was going to hell. After getting the electronic key to Cabin 11, he walked briskly out of the reception center and walked towards Cabin 11 under the guidance of the waiter.After that, Li Ren was never seen again. Could it be that he stayed in the wooden house and never came out?The restaurant in the reception center is on the second floor. It stands to reason that Li Ren must go to the second floor to eat, because there is only one restaurant in the resort, unless Li Ren brings dry food or instant noodles to eat in the wooden house.

But this possibility is very small. According to the investigation, Li Ren loves food and eats out at least 200 days a year. He will not force himself to eat instant noodles.

Wu Jiang asked the manager that their restaurant did not have door-to-door food delivery service. The manager said that it did. Many couples like to call the restaurant and ask the waiter to deliver food to their door.

They found Xiao Lin, the waiter who served Li Ren at the time, and learned about the situation. Wu Jiang said to her, "Please tell me about the situation at that time. The more detailed the better."

Xiao Lin said: "At about 20pm on the 7th, a customer from Cabin No. 11 called the front desk of the restaurant and asked us to deliver food to their door. I was in charge of delivering food. The head waiter asked me to deliver it. The customer ordered six kinds of dishes, one dish. Fish-flavored eggplant, a cucumber fish, a pound of bamboo shrimp, a pound of hairy crabs, a plate of twice-cooked pork and stir-fried cabbage sum, and also ordered two bottles of 52-degree Jiannanchun. I delivered the wine and food to the guest's wooden house three times and left. "

"He must not be the only one who orders so many dishes, right?"

"Yes, there is a man and a woman in the room. The man's surname is Li and he is about 40 years old. The woman is very beautiful and she is in her early 20s."

"What clothes does the woman wear? What does she look like? Are there any special markings?"

"It seems to be a white dress, with burgundy shawl hair, a high nose bridge, big eyes, very white skin, no special marks... Oh, there are a few youth beans on the cheekbone on the left side of her face."

"What's your approximate height?"

"You can't tell because she has been sitting on a chair and never stood up."

"Has she spoken to you? Where's the accent?"

"She only said thank you twice to me, very standard Mandarin."

"What do you think her career will be?"

"This, it's hard to say, she should be the kind of woman who hangs out in the entertainment industry, right? Yes, she can also smoke."

Wu Jiang asked her to go back to the Criminal Police Team with them to assist in the investigation. When she heard that she was going to the Public Security Bureau, Xiaolin cried and said, "Brothers, please let me go. I really didn't do anything bad."

Wu Jiang patted her shoulder and comforted her: "Xiao Lin, don't be afraid. We are asking you to assist in the investigation. If the case is solved, we will give you a bonus and we will send you back before you go to work tonight."

Xiao Lin nodded and got into their car.

Back at the police force, Wu Jiang asked Lu Yingying to make a computer portrait of the suspect according to Xiao Lin's description. Within two hours, Lu Yingying drew the woman who drank with Li Ren.

Lu Yingying uploaded her portrait to the Internet and asked citizens to help find her. She sent the investigation notice by mail to various public security units, requesting assistance in the investigation and hoping for good news.

9
From Li Ren’s cell phone call records, it was found that the last call was made to him by a woman named Wang Liran. Her name was in Li Ren’s address book, but when Wu Jiang called Wang Liran, the other party was turned off. Shut down every time.Why does Wang Liran keep turning off her phone?Could it be that she was the real murderer and absconded knowing that the police would find her sooner or later?
It would be easier if Wang Liran absconded, but the fear is that she will be silenced by the real culprit behind the scenes.

Lu Yingying printed out Li Ren's call records from the mobile company in the past six months and found that he and Wang Liran did not talk frequently. They only talked 4 to 5 times a month, and the call duration was not long. The longest call was 10 minutes, which showed that they were not lovers.
