Serious Crime Unit 1

Chapter 642 Death of a Rich Man (14)
"I understand that if the yacht is stolen, your company will be responsible. Why didn't you notice that the yacht was stolen?" Jiang Yiming looked at the security manager named Deng Shishan and asked.

"This...well...yes, we are responsible for this kind of thing happening." He replied awkwardly.

"You monitor all yachts 24 hours a day, why didn't you notice it?"

"This... it should be that the security guard on duty at the time took a nap... However, since the establishment of the Blue Water Bay Marina, the yacht has never been lost. What's more, the yacht has since been driven back to the dock, and no owner has complained to us... In short, no Cause bad consequences." He didn't know how to explain this problem.

Jiang Yiming didn't want to waste time on the issue of accountability. He and Zhou Ting fast-forwarded the video to 26 o'clock on the 12th to check it. They believed that the suspect should have returned the yacht in the early morning of the 27th. If the yacht was not returned, what would happen? It attracted the attention of the management office. Once the police called the police, the police might pursue it. Therefore, the suspect did not dare to abandon the boat and escape, but he did not dare to drive the yacht into the dock in broad daylight.

As expected, the suspect, still wearing sunglasses and a mask, drove the yacht into berth No. 27 at 03:23:23 on the 18th, then jumped from the deck into the sea, dived and escaped.

While they were checking the video, Wu Jiang, Xiao Ke, Lu Yingying and Luo Jin were investigating on the yacht. Jiang Yiming copied the video to a USB flash drive and prepared to take it back to the team for a closer look. Lu Yingying should be able to restore the suspect's appearance.

Yang Si's yacht was equipped with a locator. Jiang Yiming also asked a technician from the Blue Water Bay Marina Company to check the yacht's sailing record. The result was that after the yacht sailed 500 meters away from the dock, there was no record, which indicated that the yacht's locator was suspected. People demolished it.

What a cunning guy, able to set up one line of defense after another in such a meticulous way, trying to prevent the police from investigating.

Jiang Yiming and Zhou Ting came to Berth 18 and called Lu Yingying, who was investigating, to the pontoon and asked: "Yingying, has the yacht's locator been removed by the suspect? How can we quickly remove the locator?"

"If you want to dismantle the GPS system on the yacht, it is best to drive the yacht to an unmonitored place, then find the GPS device and directly remove the communication card installed in the GPS device. In this way, any information on the yacht will start from the time the card is removed. , the monitoring party will not know; if there is no need to worry about the monitoring party, then just cut off the negative and positive wires of the device. The latter is the fastest method."

"Did you check the locator on the yacht?"

"Look, the wire connected to the GPS communication card has been cut. The cross section of the wire is very neat. It should have been cut with a pair of sharp scissors. It also shows that the suspect has excellent arm strength."

"You made a good judgment. The suspect is about 175 centimeters tall and weighs about 75 kilograms. He is very agile and seems to have received professional training."

Lu Yingying nodded and agreed.At this time, Wu Jiang walked out of the cabin and walked up to Jiang Yiming and said: "Team Jiang, we extracted a fresh pair of shoe prints on the deck and cabin. Because the shoe prints were muddy and clear, the suspect was wearing Nike size 41." Shoes, and a large number of fingerprints were also extracted, all belonging to the same man."

"I extracted a small amount of metal particles from the keyhole, which may be left by the new key. I took them to the laboratory and used a mass spectrometer to analyze them. I should be able to analyze the elements and proportions of these metals." Xiaoke said.

Luo Jin also came out: "Team Jiang, we have been surveying for nearly four hours and have surveyed almost every inch. I found a trace amount of powder on the ground in the cab. I suspect it is copper sulfate. Take it back and check it at the scene. Compare the extracted copper sulfate, and if the data is the same, it can be proved that the suspect took the copper sulfate placed on the boat to the scene and spread it."

"Have any biological samples been extracted?" Jiang Yiming asked.This is the most critical, because biological samples can be used as DNA, which is the most reliable evidence.

"Three hairs with hair follicles and five cigarette butts were extracted, all from Zhonghua cigarettes. I don't know if they were left by Yang Si or the suspect. Both of these things can be used for DNA analysis."

"I'm worried that the hair and cigarettes were left by Yang Si. The suspect only stayed on the yacht for 24 hours at most, so the possibility of leaving hair is small." Xiaoke said.

"No, the hair may be Yang Si's, but the cigarette should be left by the suspect. First of all, Yang Si smokes not Zhonghua cigarettes, but Nanjing 1800 Supreme. These cigarettes cost [-] yuan each. He shouldn't be able to Lower your smoking standards." Both Jiang Yiming and Zhou Ting had seen Yang Si smoking, at his home, so he wouldn't smoke Chinese cigarettes on the yacht.

Because he is a person who cares about face. In terms of financial resources and abilities, he is not as good as Yang Min and Yang Rutie. However, they did not buy a yacht. Even their cars are low-end Mercedes-Benz. With their strength, they can buy tens of millions of luxury cars. It's a piece of cake.

At this moment, the setting sun is about to kiss the Western Mountains. The golden afterglow shines on the sea, dyeing the blue sea into golden yellow, like a layer of shining golden sand, and rows of yachts, like neat rows of yachts. The soldiers were quietly waiting at the Blue Water Bay Pier, shining with charming light.A great day is coming to an end.

"I used a mass spectrometer to analyze and found that what was left in Yang Si's cabin was copper sulfate, and the composition was exactly the same as what was extracted at the scene. The tiny particles in the yacht's keyhole were 7075 aluminum alloy, which is a particularly tough alloy. The chemical composition is silicon 0.40, copper 1.2-2.0, magnesium 2.1-2.9, zinc 5.1-6.1, manganese ≤ 0.30, titanium ≤ 0.20, chromium 0.18-0.28, iron 0.50, and a small amount of aluminum." Luo Jin is not talkative, he is just rigorous, Have mild obsessive-compulsive disorder.

"You mean this is a special aluminum alloy?"

"Yes, tensile strength: 524Mpa, yield strength 455Mpa: elongation 11%, 7075 aluminum alloy is a high-strength heat-treatable alloy, easy to process, good wear resistance, corrosion resistance and oxidation resistance, etc., it is the key to making Good material.”

"Are ordinary keys made of this aluminum alloy?" Xiao Ke asked curiously.

"No, if ordinary keys are made of this kind of aluminum alloy, the range is very large and there is no significance in investigating. This material is only used for precision and high-quality key production. In other words, only a very professional key production company can There are no more than ten companies like this in our city. It is most likely specially made by a company that sells yachts." Luo Jin said with excitement, as if he saw the light of day after a long night.

"Luo Jin, good job!" Jiang Yiming nodded, then turned and asked Wu Jiang, "Old Wu, have the shoe prints and fingerprints been compared in the system?"

"It has been searched, but no matching fingerprints can be found in the system, and the shoe prints have not been successfully compared. This Nike shoe was launched nationwide on January 2016, 1, and it is still hot-selling. From the thought Finding clues is almost impossible because the Nike store in our city sold about 1 pairs."

"Yingying, can you restore the suspect's appearance?"

"Because the suspect only exposed his nose, forehead, and about 2 centimeters of his chin, and the screenshots of the surveillance video are too blurry, the reconstruction using three-dimensional technology is not accurate. However, I reconstructed five rough outlines of the suspect. Look -"

Lu Yingying started the projector and started using the slides. Five men with similar faces appeared on the screen. The suspect had an oval face, a high nose bridge, a wide forehead, big eyes, a pointed chin, slightly high cheekbones, and rough skin.

"Have you seen him among the suspects you have visited before?"

"No." Everyone answered almost in unison.

"Luo Jin, have you made the DNA of hair and cigarette butts?"

"Team Jiang, not so fast. Liang Ying, Dong Dawei and I worked overtime last night to test the elements of aluminum alloys and analyze the properties of copper sulfate. We didn't finish until 11:10. Today we will start to detect DNA in hair and cigarette butts. Tonight There should be results before [-] o'clock."

"Thank you for your hard work... Let's start the investigation today from the company that made the key. Yingying will continue to check the surveillance video of Blue Water Bay Pier. Luo Jin and his assistants will do DNA. The four of us will go out for a visit."

Jiang Yiming and Zhou Ting came to Huahai Yacht Sales Co., Ltd. located in Tianshan Building. The company was on the 12th floor of the building. The entire floor was rented by Huahai Company. It was about 1000 square meters and divided into four office areas. As soon as they walked to the company At the door, the front desk lady came to greet me.

Jiang Yiming motioned to Zhou Ting to talk to the lady at the front desk.Zhou Ting is also an introverted boy, and Jiang Yiming wants him to communicate more with others, especially beautiful ladies.Zhou Ting frowned slightly, but immediately smiled and started talking to the lady at the front desk.

After the front desk lady learned about the situation, she took them to Area A to find a locksmith. The locksmith was a young man, about 25 years old, who was repairing an old copper lock, which may be a cultural relic of the Qing Dynasty. He was very focused on repairing it and did not see that they had already Walking to his side, Zhou Ting stepped forward and patted his shoulder gently: "Master, hello! We are from the Criminal Police Team of the Municipal Bureau. We want to find out the situation from you. Could you please cooperate?"

"Ah, okay, it's inconvenient because there are so many people here. Can we go to the break room to talk?" It seems that he is not only good at skills, but also has quick brain reactions. First, he is afraid that his colleagues will know that the police are looking for him and he will be suspected. ; The second is that he is worried that his conversation will be eavesdropped because he is surrounded by colleagues.
