Serious Crime Unit 1

Chapter 198 Alliance Showdown (10)
Jiang Yiming looked at the surrounding environment. It was a four-lane expressway, with two lanes for both incoming and outgoing directions. The one-way lane plus a shoulder was about 10 meters.Yang Xiaoming's car was involved in a car accident in the left lane heading from Huanggang City to Yangtze City.The left lane is the overtaking lane. There are hills on both sides of the accident site. There are dwarf pine forests growing on the hills, which look particularly green under the bright sunshine.

The curve here is not very sharp, about 60 degrees, so it is reasonable to say that it is not easy to cause an accident.Yang Xiaoming has nearly 30 years of driving experience, how could he get into a car accident?Unless he's drunk.Of course, this cannot be determined until the autopsy report is released.

Everyone worked together to overturn the car onto the road. They wanted to conduct a key inspection inside the car. Wu Jiang was responsible for all trace inspections, with Lu Yingying and Luo Jin as his assistants.

Xiao Ke and Zhou Ting conducted a more detailed investigation of the road surface, because the traffic police's investigation concept is to deal with accidents; the criminal police investigation is completely different. They have to investigate according to homicide, so they must be very patient, professional and meticulous.

After nearly four hours of investigation, the work was over. Jiang Yiming ordered the traffic police to tow the car to the Municipal Criminal Police Team's evidence warehouse in case it needed to be re-investigated.

Jiang Yiming and Zhou Ting went to the highway monitoring center to check the video of Yang Xiaoming's accident.

The video shows that at 2014:9:30 in the morning on September 6, 31, Yang Xiaoming’s car was speeding toward the provincial capital at a speed of 28 kilometers per hour.There was only Yang Xiaoming in the cab and no one else.He seemed to be sleepy. When he was approaching the scene of the car accident, his hands actually left the steering wheel and were placed on the outside of his legs, allowing the car to drive freely.Less than 150 seconds after he put down his hands, the car hit the isolation wall, then somersaulted six times in a row, and finally hung halfway on the isolation wall.From then on, the car stopped moving, and there was no sign of Yang Xiaoming struggling in the car.

Jiang Yiming asked the traffic police who participated in the on-site investigation what they thought?The traffic police said: Yang Xiaoming must be seriously drunk or given sleeping pills, otherwise it would be impossible to fall asleep while driving.Because it is only 220 kilometers from Huanggang to the Yangtze River, the car accident cannot be caused by fatigue driving.Yang Xiaoming's ticket for taking the expressway from Huanggang was found in the storage box in the cab of the car.

Jiang Yiming believes that the possibility of Yang Xiaoming being drunk is relatively small, because very few people do not drink in the morning, and Yang Xiaoming knows that he cannot drink while driving. According to the investigation, Yang Xiaoming is not an alcoholic, so how could he drink at breakfast?

On the third day, after Yang Xiaoming's autopsy report came out, Jiang Yiming convened a meeting with members of the crime team.Jiang Yiming asked Luo Jin to explain what caused Yang Xiaoming's car accident.

Luo Jin said: "Yang Xiaoming did not have alcohol, poisons, or anesthetics in his body. He was in a coma due to inhaling excessively high concentrations of carbon dioxide, so he had a car accident. The direct cause of death was a severe blow to the brain, which resulted in skull fracture and death. The deceased suffered condition Hit by a shaped object. After comparison, it was found that the strip was the steel frame of the window of the Mercedes-Benz C260, which means that during the car accident, the deceased's skull hit the steel frame on the left side of the cab."

"Carbon dioxide poisoning?" Jiang Yiming asked.

"Yes, the harm of carbon dioxide to the human body is mainly to stimulate the human respiratory center. As the amount of inhalation increases, it will cause shortness of breath, headache, confusion, cardiac arrest, and then death."

"How come there is a high concentration of carbon dioxide in Yang Xiaoming's car?"

"It should be man-made. Dry ice is the source of carbon dioxide. Dry ice is solid carbon dioxide. It is obtained by condensing carbon dioxide into a colorless liquid under a pressure of 6250.5498 kPa, and then quickly evaporating under low pressure. The concentration of carbon dioxide in the air If it reaches 10% to 20%, it will cause poisoning."

"You are saying that someone deliberately put dry ice in Yang Xiaoming's car, but Yang Xiaoming didn't notice it. In addition, the weather was a bit cold in the autumn morning. It was impossible for Yang Xiaoming to drive with the windows open, and the carbon dioxide could not be diluted by fresh air. When he got in the car, He started inhaling carbon dioxide from a moment ago, and he couldn’t feel the colorless and odorless carbon dioxide at all, so after inhaling enough carbon dioxide, he became unconscious and caused a car accident?”

"Yes, Yang Xiaoming committed suicide!" Luo Jin said.

"How much dry ice is needed to release carbon dioxide with a concentration of about 10%?" Jiang Yiming asked Luo Jin.

"It only takes about two kilograms of dry ice to achieve the purpose of killing people."

"With such a small amount of dry ice, the murderer only had to put it under the floor mat of the back seat of the car. Yang Xiaoming would never be able to tell. The murderer is really clever. He walks in front of us every time...Old Wu, did you leave anything in the car?" Clues to the value?" Jiang Yiming asked.

"In addition to Yang Xiaoming's bloodstains, there are many messy fingerprints in the car. There are two fresh fingerprints, most of which are covered with other fingerprints. According to comparison, one of the fingerprints belongs to Yang Xiaoming; the other belongs to a woman . There are only two fresh shoe prints, one is Yang Xiaoming’s; the other is a woman’s high-heeled shoes.”

"Is this woman most likely the murderer of Yang Xiaoming?"

"That's the truth. However, our opponent is very smart. She probably won't leave such obvious evidence to us."

Jiang Yiming nodded and asked Luo Jin: "How long does the dry ice need to be left in the car to completely vaporize?"

"It depends on the thickness of the dry ice. Crushed dry ice will take about two to three hours."

"Did the murderer put dry ice into Yang Xiaoming's car two or three hours before his car accident?"

"Yes. It was around three or four in the morning. The moon was dark, the wind was high, and it was quiet at night. It was the best time to commit the crime."

"But how could the murderer open Yang Xiaoming's car?" "It should be an acquaintance who committed the crime and copied his mechanical key; or he was an electronic unlocking expert. More than 100 cars are stolen in the city every year. Most thieves use the electronic lock to unlock the car. Decode it and steal the car.”

"Then, as long as we check Yang Xiaoming's driving route backwards, we should find out where Yang Xiaoming came from in Huanggang City." Zhou Ting said.

"Huanggang City has a large population and a large area. It's a lot of work to check where Yang Xiaoming comes from. What's more, the traffic monitoring system in Huanggang City is not as complete as that in the provincial capital. There must be monitoring blind spots. The fastest shortcut is to find Yang Xiaoming's family members and employees. Do you know why he went to Huanggang? Where he settled..."

"His wife doesn't know where Yang Xiaoming went that night. It's useless to look for his wife. It might be useful to look for his employees and shareholders." Wu Jiang interrupted Xiaoke.

"Let's see, Zhou Ting, Xiao Ke and I went to Huanggang to check the traffic video. Lao Wu and Yingying went to Yang Xiaoming's company, and you two went to find his employees. We must compete with the murderer for time, and we can't let the suspect die unexpectedly. This The case is a race against the murderer. He is much more powerful than we thought and always cuts off clues at critical moments. We can't make any more mistakes." Jiang Yiming divided the work.

Serious Crime Team No. 1 merged the cases of Luo Liangcai, Li Ren and Yang Xiaoming for investigation. Because the reasons for merging the cases were very good, Deputy Director Xi agreed.

The next day, when Wu Jiang was at work, he remembered that Yang Xiaoming's Mercedes-Benz was equipped with a Noxing locator. He came to Lu Yingying's office and asked Lu Yingying if he could find out where the car had appeared from the GPS locator.
Lu Yingying said it should be no problem.She turned on her computer and started to crack the login password of Yang Xiaoming's locator. After nearly an hour, the password was cracked by Lu Yingying.She logged into the microcomputer system of Yang Xiaoming's car and wanted to find out where the car had appeared. However, she did not expect that Yang Xiaoming turned off the locator as soon as she got on the Huangchang Expressway, causing Lu Yingying to waste her efforts.

"Why does Yang Xiaoming turn off the locator as soon as he leaves the suburbs?" Wu Jiang asked.

"First of all, Yang Xiaoming might do something shameful, such as drug trafficking, smuggling, and having a tryst with a mistress; second, the locator might not be turned off by Yang Xiaoming, but by the murderer who invaded his microcomputer system. In this way, even if the police We suspect that Yang Xiaoming committed suicide, and we can’t find the location of Yang Xiaoming’s car.”

"Which scenario do you think is more likely?"

"The possibility of the car microcomputer system being hacked is relatively small, because this requires very professional network technology; Yang Xiaoming is most likely to turn off the locator, because he is afraid that his wife will use a computer or smartphone to find out where he is. We know Yang Xiaoming’s wife, Lin Xinger, is often suspicious and is very worried about Yang Xiaoming, so she suffers from depression.”

Wu Jiang and Lu Yingying came to Yang Xiaoming's company, and the receptionist looked sad.Seeing them coming, he forced out a smile and said, "You guys are late. Mr. Yang got into a car accident and left."

"We know this. This is exactly what we came for." Wu Jiang said.

"As far as I know, you are criminal policemen from the city bureau's serious crime team. Isn't Mr. Yang's death an accident?"

"Yes, it may not be an accident, so we have to investigate in depth. I hope you can help us."

The front desk lady looked at Wu Jiang with big astonished eyes and asked, "How could someone murder Mr. Yang?"

"We can't be sure until the facts are clear... Do you know what Mr. Yang went to Huanggang for on September 9?"

"How do I know this?" She shook her head.

"Who does Mr. Yang have the best relationship with in the company?"

"It should be Vice President Li. Vice President Li is Mr. Yang's friend and one of the shareholders. When the company has important events, Mr. Yang almost always brings Vice President Li with him."

"How much share does Vice President Li hold in the company?"

"Accounting for 30%, Mr. Yang holds 51%, and the rest is equally divided among the other five small shareholders."

"Is Vice President Li in the company?"

"Yes. Vice President Li is now in charge of the company's overall work."

"Please take us to Vice President Li."
