Serious Crime Unit 1

Chapter 1276: Car Crash (5)
"The pathological analysis is still in progress, but even if it is known that he suffers from a certain disease, it will not be a clue of great value in solving the case, because homeless people will not offend people. The murderer just randomly killed a homeless man and asked him to replace Mercedes-Benz. The driver came to confuse us. The deceased had no identity and was killed randomly. It is very difficult to find the murderer through the identity of the homeless man." Luo Jin answered Xiao Ke.

"Luo Jin is right. We should investigate Nan Nan's social background to see who has the motive for the murder. Nan Nan must have offended some capable murderer, which would lead the murderer to kill the homeless man to cover up the truth. Fortunately, he met We can only blame the murderer for his misfortune! If Lu Mingli and Captain Jiang hadn't known each other, this murder case would have been treated as a traffic accident by the traffic police brigade." The anger in Xiao Ke's eyes was burning.

"Don't brag. Do you still remember the hacker hired by Hua Baifang? Xiaorou and I have been looking for the hacker's intrusion path whenever we have free time, and we haven't found it until now." Lu Yingying glanced at Xiaoke, and then said to Jiang Yiming , "Xiaorou and I went to check those two cars. The BMW should be equipped with a tracker or hacked, otherwise the hacker would not be able to know the whereabouts of the BMW."

"Okay, Lao Wu and Xiao Ke are going to investigate Nan Nan's social background. Zhou Ting and I are going to ask Yu Huan to see where her car was parked and stolen. Luo Jin continues to search for the identity of the driver of the Mercedes-Benz. Let's break up the meeting. ." Jiang Yiming put away his laptop on the table and walked out of the conference room.

Lu Yingying and Wen Xiaorou brought their laptops to the Jiangbei District Traffic Police Brigade to find Hu Xin and explained the situation to him. He then took them to the evidence warehouse, entered the password, opened the door, and then pointed to the BMW on the left and said: "This It's Nan Nan's car. The car on the right is the car of Anonymous. You guys take your time to look for physical evidence. I'll go to work first. If you have any instructions, just call me. I'm very willing to help you."

"Captain Hu, how dare we give you orders? You go ahead and do your work. We are about to start working." Lu Yingying smiled and waved to him, and he strode out of the warehouse.

Lu Yingying is responsible for inspecting the Mercedes-Benz, while Wen Xiaorou is responsible for inspecting the BMW.The roof of the evidence warehouse is covered with iron sheets. Although it is 8 meters above the ground, the scorching sun burns the warehouse like a furnace. The summer in Yangtze City is very long. It has been 12 days since the summer heat, and the heat is still unbearable.

They had only worked for half an hour and were already sweating profusely. Even their underwear was soaked and clinging tightly to their bodies. They wished they could take off their shirts and work shirtless like men.

Lu Yingying discovered that there was a rectangular controller installed on the chassis of the Mercedes-Benz. There was no such thing on the Mercedes-Benz, and it was obviously installed artificially.The controller is about 8 centimeters long, 6 centimeters wide and only 3 centimeters thick. It is tightly fixed to the chassis with welding glue.

With this controller, you can remotely control a Mercedes-Benz to hit a BMW.Its wires were connected to the microcomputer of the Mercedes-Benz. Although the wires had been burned and even the copper wires had been melted by the fire, an expert would know at a glance that it was the culprit.

Lu Yingying removed the controller and put it into the evidence bag, and then went to check the car's microcomputer. It was installed on the main body of the dashboard. Everything that could be burned in the car was burned out. Only the microcomputer could not be completely burned because its casing was made of aluminum plates. Yes, but the chip's high temperature resistance limit is 400 degrees Celsius, and the temperature when Mercedes-Benz burns exceeds 800 degrees Celsius, so the chip should be destroyed.

Although Lu Yingying knew that the chip was most likely burned, she still removed the microcomputer and put it into the evidence bag.It doesn't matter that she's not expert on chips, they can find experts to crack or repair them.

Wen Xiaorou found no controller or tracker on the BMW. They checked it all morning and felt that the inspection work was in place, so they called it a day.After returning to the team, Lu Yingying reported the situation to Jiang Yiming.Jiang Yiming asked her what the controller does?
"The controller is just a single-board computer. It is very simple and can be bought online for 500 yuan, but it is very powerful. The murderer secretly put a forged panel on it and connected it to the car's microcomputer, so that he could control the Mercedes-Benz with his mobile phone. It can control almost all smart things. The murderer used a Bluetooth transmitter plugged into the circuit board and connected it to the car's microcomputer to control the Mercedes-Benz to crash into the BMW."

"Can you find out who controlled the Mercedes-Benz from the controller?" Jiang Yiming asked.

"If the chip without the controller is not damaged, there should be rules to follow. However, the extreme high temperature of the chip is 400 degrees Celsius, and the temperature when Mercedes-Benz burns is as high as 800 degrees Celsius, so the chip should have been damaged. Of course, I have no idea about the chip. Not very expert, we need to find a chip expert to see if it can be repaired. If it can be repaired, there is hope that the murderer can be found." Lu Yingying wished she was a chip expert.

"It shouldn't be difficult to find experts, right? If the city's chip experts cannot repair the chip, the provincial department can come forward and send it to the Ministry of Public Security, so that the Ministry of Public Security can find a way to solve the problem. After all, these are two lives, and the Ministry of Public Security will definitely help. Yes." Jiang Yiming said confidently.

"I agree with your idea. However, don't put too much hope in the chip. I know that it is difficult to repair the chip if it is physically damaged. We still have two clues. One is to find the car thief; the other is to find the right person. Nan Nan has a grudge. This should not be a murder case, otherwise the car thief would not have used several 10 yuan Mercedes-Benz cars to hit Nan Nan's car. I think it is a vendetta case, and the vendetta case should be more serious than Nan Nan's. Is it easy to detect a financial murder? Because there may be many accomplices in a financial murder case, but there will be very few accomplices in a revenge murder case. Usually the murderer acts alone." "You are right. I went to visit Yu Huan with Zhou Ting today and asked her She said her Mercedes-Benz was stolen from where it was parked. She said Ai Xiaoqing drove the Mercedes-Benz and she didn’t know where it was parked. It was Ai Xiaoqing who called the police."

"Why not ask Ai Xiaoqing?" she asked.

"Oh, Ai Xiaoqing's cell phone has been out of reach for several days. I was just about to ask you to help locate his cell phone. I suspect he may have been killed. Zhou Ting and I analyzed that this matter may be related to Ai Xiaoqing. You Would Ai Xiaoqing give the keys to the Mercedes-Benz to the murderer and then be silenced by the murderer? It’s not that easy to steal a Mercedes-Benz, right?"

"The possibility that Ai Xiaoqing will be silenced by the murderer is very small. If he is silenced by the murderer, the murderer will not have to kill the homeless man and treat the homeless man as a living person to drive. He will directly use Ai Xiaoqing's body as the driver. Isn't it more convenient to drive? And it won't leave any loopholes... The Mercedes-Benz 350 is an older car and is no longer produced, so its firewall password is not complicated. Hackers can use the controller to control Mercedes-Benz, which means He can also hack into a Mercedes-Benz without Ai Xiaoqing's key."

"Then where do you think Ai Xiaoqing will go?" Jiang Yiming thought Lu Yingying was right.

"It's hard to say. I think he may have traveled somewhere with his little lover. In order to prevent Yu Huan from finding him, he blocked the signal of his mobile phone. Nowadays, many IT technicians who help employers locate mobile phones also pay to help others locate their mobile phones. The software makes it very convenient to find a person, so I think Ai Xiaoqing is hiding. Of course, this is just my conjecture. In short, I think Ai Xiaoqing is not in danger."

"You should be careful. I didn't expect this to happen, I hope it won't be like this." Of course Jiang Yiming doesn't want one more person to die. There is only one life, regardless of high or low, no matter how humble a life is, it is priceless.

Lu Yingying went to locate the location of Ai Xiaoqing's mobile phone, but the result was as expected: it could not be located.There are three reasons for this phenomenon. First, the mobile phone is buried in the soil or thrown into water; second, the battery of the mobile phone is removed; third, the owner puts the mobile phone into a jammer.Ai Xiaoqing is most likely the last one.Lu Yingying turned on the 24-hour tracking mode of Ai Xiaoqing's mobile phone. Once his mobile phone is turned on, she will receive his mobile phone signal, and the computer will automatically transmit his location to her mobile phone. Even if she sleeps, she will be woken up. .

Lu Yingying called China Eastern Airlines to check if Ai Xiaoqing had bought a ticket to Tibet?As a result, the airline conductor said that Ai Xiaoqing had not purchased a ticket from China Eastern Airlines this week.Lu Yingying thought for a moment and then entered the guest check-in registration system. Nowadays, most hotels and guesthouses' monitoring systems and accommodation registrations are connected to the Ministry of Public Security, and detailed information about guests can be found quickly.

Lu Yingying found out that Ai Xiaoqing and a woman named Qin Meiyue stayed at the Binhai Hotel in Sanya and lived in the same room.Lu Yingying was secretly happy: As expected, Ai Xiaoqing and her little lover went out to have an affair!Modern love is too fragile.She suddenly remembered Mu Xin's poem: "In the past, the sun became slower, the cars, horses, and mail were all slower. There was only enough time for one love in a lifetime..."

Lu Yingying liked the last sentence the most: "You can only love one person in a lifetime." With this sentence alone, she admired Mu Xin very much.When she was in the police academy, she read this sentence, and her heart seemed to be suddenly struck by electricity, and her eyes filled with tears. But why is modern love so fragile?

In her more than ten years as a police officer, she has gone from being sentimental to being strong and unyielding, and she no longer sheds tears easily, because she has seen too many life, death, separation, and human tragedies, and her heart has grown cocoons.Recently, she was reading "Dull Sensibility" written by Japanese writer Junichi Watanabe, and felt that his writing was very good. She should not be too sentimental in life, otherwise it would be harmful to her spiritual growth.

Lu Yingying went online to find the main reception phone number of Sanya Binhai Hotel, and asked the operator to connect the phone to room 1909 and report her police number. The waiter did so.
