Serious Crime Unit 1

Chapter 641 Death of a Rich Man (13)
"It's very simple. The wires are connected to the motor boat. As soon as the ship sails away, the wires will be towed away by the ship. This can save time for collecting the wires, because the murderer is afraid of being discovered before the wires are recovered. Especially the police who are closest to the scene, so this is the best way to collect the wire."

"If this is the case, the wires must have been buried shallowly on the beach. Then, when the murderer dragged the wires away by boat, the wires would leave traces of dragging on the beach. But why didn't we find it?" Zhou Ting was a little bit confused. Puzzled.

"The wires left traces of dragging. However, the wind was at its strongest that day, reaching level [-] or even level [-]. The dry fine sand on the beach was blown by the wind, thus burying the traces. Of course the murderer also thought of this. , so he had to choose a day with strong winds." Jiang Yiming explained.

"Yes, the slope of the beach is nearly 10 degrees. The closer to the villa area, the higher the beach. The higher the beach, the drier it is. The drier sand is lighter, so it is easier to be blown by the wind, and we are only 10 meters away from the site. We surveyed an area of ​​10 meters, so no traces left by wires were found. Even if there were protrusions on the beach, they were mistakenly thought to be sandbag crabs, fiddler crabs, ghost crabs, hermit crabs, mudskippers, lugworms, and shore sandpipers. , conches, clams and other creatures."

"If we had searched offshore, we might have found traces of wires. The closer to the sea, the harder it would be for the wind to flatten the beach traces, because the sand has high humidity and is particularly heavy." Xiao Ke said.

"Luo Jin, can the electric energy emitted by a motor boat electrocute people to death?" Jiang Yiming is not expert in electricity. Although Luo Jin's major is forensic medicine, physics is also a required course. He is certainly more professional than those here.

"Of course the electricity from the engine can electrocute people, because it is alternating current. Although the voltage of 220 volts cannot electrocute people immediately, the murderer can also use a booster to increase the voltage to two or three times, so that he can Yang Min’s family was electrocuted instantly.”

"Then, the suspect should have certain knowledge of chemistry and physics, and may be a professional electrician, because he knows how to use copper sulfate and pressure increasers. He also has a motor boat, or rents a motor boat, so the scope has been narrowed. There are many, so let’s investigate based on this suspect profile.” Jiang Yiming said.

"Captain Jiang, I think Yang Si is the biggest suspect. He can pay to kill people, and his motive is also the biggest. Therefore, Yang Si's alibi is useless."

"Okay, Lao Wu is right. Let's continue to investigate Yang Si and Shi Xiangqi. My sixth sense tells me that Shi Xiangqi is definitely not a good bird. Zhou Ting and I went to check all the friends Yang Si has, Lao Wu and Xiao Let’s check Shi Xiangqi’s social background.”

Jiang Yiming and Zhou Ting came to Gu Linming's office again, and Gu Linming still looked worried.

"Mr. Gu, has Yang Si ever bought a motor boat?" Jiang Yiming asked the key point.

"Motorized boat? Is it for fishing or transporting goods?"

"No, that includes all motorized vessels."

"Oh, he owns a Yamaha yacht, but he rarely uses it. I only went on it once. That time he took me to Sansha Island to eat seafood on the yacht. He wanted to win me over and help him get the general manager position. "At that time, I verbally agreed to him, but actually didn't do anything for him, so he was a little disappointed that I didn't keep my promise, but he couldn't blame me, so our relationship gradually faded away."

"Oh? Where is the yacht parked now?"

"That time I got on the boat at the Blue Water Bay Pier. It should be parked at the Blue Water Bay Pier. Most of the yachts and speedboats in our city are parked there. They are centrally managed by the Blue Water Bay Yacht Management Company and charge by the hour. It’s like a parking lot.”

"Thank you for the information you provided. In order for Yang Min's family to be happy as soon as possible, I don't have time to talk to you anymore. We will come to you again in the future... Oh, the content of our conversation with you today must be kept confidential."

"Okay, I know, I will definitely keep it secret, don't worry." He touched his smooth forehead and waved goodbye to them.

The marina has the functions of berthing, cleaning, repairing, and allowing tourists to get on and off the boats.In the past, people's concepts of yacht docks were mostly reinforced concrete structures. However, because the water level often changes, yacht docks with this structure often cannot meet the requirements. Floating docks can adapt to different water levels and always maintain a fixed distance from the water surface. They are increasingly subject to Favored by many users.

Bluewater Bay Terminal is the most advanced aluminum alloy pier. It has excellent anti-corrosion capabilities, convenient transportation and super endurance. These characteristics make it almost once installed and used permanently.Even if the pontoons and panels age, as long as some parts are replaced, the aluminum alloy dock will look new again.

Blue Water Bay Pier is located in the southeast of the city, nearly two kilometers away from the exit of Qianjiang. There are many kinds of yachts on the pier, densely packed together, and the white hulls and sails are reflected on the blue sea. A seagull flies back and forth between the masts, forming an excellent beauty. It is also one of the favorite places for wealthy people on the Yangtze River.

Jiang Yiming and Zhou Ting came to the management office of Blue Water Bay Pier. The administrator was a beautiful girl with scary big eyes that did not match her facial features.After checking their police IDs, she turned on her computer and looked for Yang Si's name, and found it quickly.

"Two police officers, Yang Si has a Yamaha UF310 yacht parked at our dock on August 2013, 8. It has not changed docks until now. It is our loyal customer." Her eyes were like crystals. Just as clear.

"Can you take us to find this yacht? Your pier is so big that it stretches as far as the eye can see." She looked at Zhou Ting and then at Jiang Yiming. Maybe she thought they were particularly handsome, so she said, "Originally, I am I don’t dare to leave my post, but in order to cooperate with the police, even if our manager knows, there is no reason to blame me. Let’s go!” She walked towards the pontoon of No. A4, and they followed behind.

The pontoon was very long, with many berths on both sides. The various gorgeous yachts dazzled them both, and they secretly lamented that there were so many rich people in Yangtze City.

After walking for 5 minutes, she arrived at berth No. 18, pointed at a yacht and said, "Two police officers, this is Yang Si's yacht."

"Thank you, you go and do your work first." Jiang Yiming smiled and nodded, and she slowly turned around, seeming a little reluctant to leave.

"This girl is from the Appearance Association," Zhou Ting said with a smile.

"Everyone has a love for beauty, and who doesn't like it when it comes to eating, drinking, and drinking?"

"Haha... Captain Jiang, this yacht is most likely the culprit."

"The yacht is not guilty, but the murderer is guilty."

Zhou Ting walked to the side of the yacht and wanted to go up to check, but Jiang Yiming stopped him: "Don't move, don't destroy the physical evidence and traces."

Zhou Ting stopped quickly: "What should we do next?"

"Let's go to the control room at the pier to see if the yacht has left the pier at the time of the crime."

They came to the control room on the second floor of the Bluewater Bay Pier Management Center and asked the security guard to bring up the surveillance video of berth 8 on the morning of August 26 for them to review.The security guard knew that they were from the criminal police team of the city bureau, so he cooperated with them and quickly pulled out the video they asked for.

They sat down and checked. From 8 a.m. to 26 a.m. on August 9, the yacht was not berthed at berth 11. This meant that someone had driven away the yacht, and it was definitely not Yang Si or Shi Xiangqi. They left because they were both at the Beihai Hot Spring Hotel in Bei City at that time.

The only possibility is that the yacht was driven away by the murderer. Then, the murderer was most likely hired by Yang Si with money. If this is the case, then the case is not far away, because a man who can drive a yacht, be an electrician, and can use... People who conduct electricity with copper sulfate are easier to find among Yang Si's connections.

There is another possibility that the yacht was borrowed by Yang Si's friend, but this possibility is unlikely.The quickest way to find out who drove away the yacht is to check the surveillance video.

Jiang Yiming thought about it and thought that the suspect would not drive away the yacht during the day, because the light during the day was very good. No matter how he covered his face, it would be captured by the monitor, and then he used a computer to create the outline of his face. .

Jiang Yiming called Wu Jiang and Xiao Ke and asked them to get the investigation box. Lu Yingying and Luo Jin also came together, because Lu Yingying was best at surveillance video, and Luo Jin was very knowledgeable about tiny compound particles, and Wu Jiang was extremely accomplished in trace identification. deep.

8
Jiang Yiming and Zhou Ting continued to check the surveillance video and saw that at 26:02:31 on the 31th, a man suddenly emerged from the water, climbed onto the pontoon of berth 18, and then jumped onto Yang Si's yacht. He took out a key from his pocket and opened the cabin door of the yacht.

Wearing a pair of black waterproof masks and sunglasses on his head, he is about 175 centimeters tall, 5 centimeters taller than Yang Si.Jiang Yiming had seen too many surveillance videos and could tell his height at a glance, mainly because Jiang Yiming found the basic data of the Yamaha UF310 yacht. The height of the yacht hatch is 180 centimeters, so he could determine the suspect's height.

The suspect calmly walked into the cabin, started the yacht and drove away.The anti-theft system of a yacht is very strict, especially the ignition key, which is relatively sophisticated and difficult to copy.After the yacht left the dock, it headed north, which is the direction of the Gold Coast villa area.Of course, if you want to determine the navigation route of the yacht, you must also check the voyage recorder.

The navigation records of each yacht are recorded in the computer system of the Bluewater Bay Marina Management Office.
