Serious Crime Unit 1

Chapter 973 The perfect alibi (7)
"Why didn't the murderer jump into the sea himself, but hired someone to jump into the sea? Wouldn't it be more risky if one more person knew?" Jiang Yiming believes that the murderer is more likely to jump into the sea himself.

"Xiao Ke and I have measured that the drop from Yingzui Rock to the sea is 29 meters. If you are not a professional diver who jumps from it, there is a great possibility of being knocked unconscious by the sea water. Once a person is knocked unconscious, he will lose consciousness. In this case, he would definitely be drowned, and the murderer would not take the risk unless the murderer was a high diving athlete. So I think the murderer is most likely to hire someone to jump into the sea."

"Old Wu, you are right. Luo Sheng must have committed suicide. Since the man who pretended to be Luo Sheng and jumped into the sea was a diver, I think it will not be difficult to find him out of the crowd, right?"

"Yes, we are getting closer to the murderer." Wu Jiang chuckled.

"It would be great if we could find the crime scene so that we could extract the murderer's shoe prints, which would be of great help in solving the case."

"Xiao Ke and I met with Shen Xiaocheng and asked him where Luo Sheng would fall into the water? He said that based on the water speed and wind direction on June 6 and 20, Luo Sheng's fall into the water would not be farther than Yingzui Rock. kilometers, so as long as we start looking north from Yingzui Rock, we should be able to find the location of the crime, but this is a bit difficult." Wu Jiang looked out the window and said.

"It's not difficult. The murderer must have pushed Luo Sheng into the sea on the coast. As long as we search along the coastline, I believe we will find the crime location soon." Jiang Yiming is very confident, because there is only one line to find the crime location. , rather than a radius of one kilometer.

"Can we use police dogs to find the location of the crime?"

"The time that human body odor remains on objects is limited by natural conditions. If it is in a closed room, human body odor can be preserved for more than half a year. However, our crime scene is at the seaside, and the strong sea breeze and humid air quickly remove it. It will dissipate the smell, and it’s been a week since the incident, so police dogs may not be able to find it.”

"We all know that Luo Sheng smokes and suffers from diabetes, and the person who invited him to the scene must be his friend or acquaintance. After they met at the scene, they should have had a conversation. During the conversation, the murderer took advantage of Luo Sheng's unpreparedness and Suddenly push Luo Sheng into the sea. If Luo Sheng smoked while they were talking, then his cigarette butt would remain at the scene, and Luo Sheng's saliva would remain in the cigarette butt. The saliva stored in the cigarette butt is not easy to evaporate. , and the saliva has the smell of Luo Sheng, so police dogs will definitely sniff it out, so I think police dogs should be used to find the location of the crime." Wu Jiang insisted on his opinion.

"Okay, let's go find the crime scene according to your ideas. I'll call Xiao Bing and ask him to see what he says." Jiang Yiming picked up the landline and called Xiao Bing. Xiao Bing is the police dog of their municipal bureau. Trainer, very experienced.

After the call got through, Jiang Yiming explained the situation to him.

Xiao Bing said: "Captain Jiang, have you forgotten Xiaohu's ability? Xiaohu has an indomitable and magical olfactory tracking ability. He can track odors even for more than half a month, and has set a record of continuously tracking 220 kilometers. It has 3.5 With billions of olfactory cells, it is one of the best among tracking dogs.”

"This is great. Bring Xiaohu right away and we will go to the scene with you." After Jiang Yiming put down the phone, he gathered the members of the No. 1 Serious Case Team together and prepared to go.

After a while, Xiao Bing brought Xiao Hu. Luo Jin put Luo Sheng's shoes into the evidence bag and gave them to Xiao Bing, because the shoes can be used as a smell source. Only with the smell source can Xiao Hu find the target.

They drove two police cars, parked them outside the Diamond Waterfront Villas area, then got out and walked to Eagle Beak Rock.Xiao Bing took out Luo Sheng's shoes and asked Xiaohu to smell them. After sniffing, Xiaohu nodded, indicating that he had remembered them. So, everyone followed Xiaohu and searched all the way north.

After a while, they entered the pine forest.This pine forest is rarely visited by people. The ground is covered with pine needles and covered with weeds and shrubs. There is no grass in some places, exposing the soft land. Many kinds of birds sing among the branches, making pleasant sounds. Feeling relaxed and happy.

After everyone searched for half an hour, the tiger barked at the root of a pine tree. Xiao Bing knew that it had found the target. He walked forward, squatted down and observed, and sure enough he found a cigarette butt, which was a Liqun brand cigarette butt. Xiao Bing smiled. Then he said to Jiang Yiming: "I found it, Captain Jiang. This cigarette butt must have been left by the deceased."

"That's great. I didn't expect Xiaohu to complete the task so quickly. I really want to thank Xiaohu. Of course, I also want to thank you!" Jiang Yiming spoke without hesitating.

"Captain Jiang, this is what I should do. Why are you thanking me? I am your soldier and I will be here whenever you call."

Jiang Yiming nodded and asked everyone to stop, put on shoe covers, and investigate the scene.The main thing is to extract the footprints at the scene, and secondly, to look for the physical evidence left at the scene, such as cigarette butts, plastic bags, packaging boxes and the like.

After Jiang Yiming put on his shoe covers, he walked towards the East China Sea and came to the coast.This is a cliff that extends to the north. The cliff is about 30 meters away from the sea. The water is very deep. The waves hit the steep stone wall, making a roar. If Luo Sheng, who cannot swim, is pushed down from here, No chance of survival.Wu Jiang and Xiao Ke extracted 30 fresh shoe prints from hundreds of square meters of ground. Wu Jiang analyzed that these footprints were left by two people, one was Luo Sheng's shoe print; the other should be the murderer.The murderer's shoe prints were of size 41 leather shoes, but he didn't know what brand they were and had to go through a computer comparison to confirm.

Wu Jiang analyzed the shoe prints and believed that the murderer was between 174 and 177 centimeters tall, weighed about 70 kilograms, and was a man with a splayed figure.

Luo Jin and Zhou Ting picked up six cigarette butts on the ground. They were three unbranded cigarettes, three plastic bags, two empty mineral water bottles, and a colored plastic sheet. This plastic sheet was already very old. For more than half a year, this may have been left by people having a picnic here and has little value.

After the on-site survey was completed, the sky had darkened, and the sunset dyed the sea water into golden yellow. The fishing boats returning late slowly sailed into the port. The fishermen took the harvest of seafood home, and the lanterns in the distance lit up one after another, like A string of beautiful notes.Everything is so beautiful, who would have thought that a murder would happen on this peaceful and beautiful seaside?

Luo Jin processed the cigarette butt smelled by Xiaohu, extracted a biological sample - saliva, and made DNA from it. He compared it with Luo Sheng's DNA. As expected, the coincidence rate between the two was as high as 99.99%. , it can be inferred that Luo Sheng was pushed into the sea on the cliff in the pine forest.

Luo Jin also extracted biological samples from the six cigarette butts he picked up and made DNA. The samples belonged to three different people.He took it to the database for comparison, and found no match. In other words: if one of the three people was the murderer, he had no criminal record.

Luo Jin kept the DNA data of these three people. If the murderer was caught, after comparison, if one of the DNAs belonged to the murderer, then this would be strong evidence.

Wu Jiang and Xiaoke put the shoe prints collected at the scene into the database for comparison, but they also found no results. However, they found out that the suspect's shoes were Fuguiniao brand products produced in 2019.This is a well-known brand of shoes in China. The price is about 300 yuan, which is affordable to ordinary people. In other words, the suspect is not a rich person, but a middle-income group, such as white-collar workers.

Jiang Yiming was sitting in the office thinking about how to find clues. Suddenly his cell phone rang. When he saw that it was Kong Ziming, he pressed the answer button: "Hello, Mr. Kong, do you have anything to report to me?"

"Yes, Captain Jiang is really a prophet. I want to report the situation to you... It's like this. After my divorce, I did pursue Yang Binghua, but she declined. But I didn't give up and kept courting her. Invite her to dinner, sing songs, and send flowers, but she just doesn’t want to do this..."

"Don't you feel disgusted that you do this even though you know she has a husband?"

"Of course we businessmen are not as noble as you policemen. I don't feel disgusted. I just feel like a failure. However, I didn't give up and continued to pursue her. Finally one day, she confessed after drinking and told me that she loved She fell in love with Jin Zihua and told me not to spend money on her. I didn't believe it, so she immediately pulled out the indecent photos of her and Jin Zihua from the private space of her phone and showed them to me. After I saw them, I was very angry and finally I understand why she rejected me."

"What does Jin Zihua do?"

"He is the boss of Jinzi Ceramics Company. Although he is not very rich, he is richer than me, so I feel inferior. But I am better than Jin Zihua because I am 12 years younger than him. Jin Zihua is already 46 years old. I don't understand Yang How could Binghua fall in love with a little old man?"

"Isn't Jin Zihua married?"

"Divorced, he has two daughters, one with him and one with his ex-wife... Jin Zihua used to be a gangster on the street. He accumulated a certain amount of funds by following a gray path, and then engaged in the ceramics business. Now His assets are almost tens of millions of yuan. I think he is most likely to kill Luo Sheng."

"why?"

"Because Yang Binghua doesn't want to divorce Luo Sheng, so if Luo Sheng dies, he will have a chance to get Yang Binghua."

"The information you provided is very valuable. We will investigate it. Don't worry, we will never let a bad guy go. No matter how rich he is, it will be useless." After Jiang Yiming hung up the phone, he opened the household registration system and entered the computer I searched for Jin Zihua who was born in 1974, and found three people with the same name.
