In order to protect the privacy of guests, there is no monitoring around the villa, there is a big monitoring gap, which also brings trouble to the investigation, and the villa has three exits, and the lake is also open, you can leave the villa through the side door, or even climb over the wall, you can also leave from the lake.

The check-in records kept by the lodge are also fake.

Li Xiao investigated the surveillance around several gates of the villa, but did not find any trace of Professor Wan.

On the other side, Luo Cheng and Dai Lin walked into the scene together, the sofa overturned on the wall, there were three neatly arranged scratches on the sofa, and there were splash-like blood stains below, the blood stains extended to the bathroom, the table lamp left the lamp holder and shattered in the opposite corner of the wall, the root carved coffee table also fell, and a pair of crushed glasses were extracted under the coffee table, the spider plant by the window was broken and scattered, there was a wooden stool with a broken leg at the door, the door lock on the bathroom door was damaged and flew, and there was a bloody handprint on the tile on the bathroom wallThere were a large number of dripping blood stains on the toilet bowl, and there was an obvious drag mark on the ground.

The door to the living room was intact without any signs of breakage, and no valuable footprints were extracted around the house due to the rain yesterday.

After laboratory tests, it was finally determined that the bloodstains were Professor Wan's.

Later, Dai Lin found Professor Wan and Wei Ling's hair and skin tissue in the bathroom, which was also reflected in the bed, in addition to these garbage baskets, there were also used condoms. Judging from the traces at the scene, it is very likely that Professor Wan has been killed.

Luo Cheng circled around the villa a few times, and finally calculated the distance from the villa to the mirror lake, the straight-line distance is only more than 30 meters away, there are several artificial islands in the lake, the entire mirror lake villa and leaning on the crescent-shaped bay, the open water can reach the scene of the crime almost anywhere, and similarly, as long as the water is good enough, you can escape from the scene.

Back at the scene of the crime, Luo Cheng turned around a few times again, Xiao Wu had already placed the scattered things where it should be according to Luo Cheng's instructions, and at the same time pulled out the movement trajectory with a thin line, and the whole room was filled with dense and colorful thin lines for a while, and all kinds of spilled blood stains on the ground also marked the movement trajectory with red lines.

"I've seen this method of yours on TV, and many people in Europe, the United States and Hong Kong use it, it's very cumbersome, and it's worthy of studying." Dai Lin now sincerely admires Luo Cheng, this guy is not only good at criminal psychological simulation portraits, but now the level of trace identification has also reached a height that everyone can only look up to.

Luo Cheng squatted down and looked at the bloodstains and pulled out the red line, and said: "There are many kinds of bloodstains, and there are corresponding laws behind each bloodstain, the same height If the strength angle is different, the shape of the bloodstain will change, the greater the strength, the higher the height, then the blood will splash everywhere, and there is a circular splatter-like bloodstain on the ground, if the angle is oblique, then the trace of this bloodstain will also be oblique, and the direction of the blood splash will also change, As long as you measure the strength of each drop of blood, you can deduce the victim's condition at the time, I once visited the Chinese detective Li Changyu, what he is best at is this, in order to be more intuitive, I have imported the data into the computer, you can take a look. ”

"Software so soon?" Dai Lin was a little incredulous.

"That's nature, and you don't look at what I'm doing?"

Li Xiao walked in from the outside with a bag with a computer, he opened the bag and took out the relevant equipment, and it didn't take long to build a strange-looking device on the table, with the start of the computer, a complete miniature version of the 3D holographic projection appeared in front of everyone's eyes, 3D holographic projection is equivalent to a 2D TV picture three-dimensional, and it looks much more intuitive at a high level.

Everyone present couldn't help but be a little surprised, especially a few veteran police officers, who had never seen such a high-tech thing in their decades of working as a policeman.

The internal structure of the entire villa appeared in front of everyone's eyes completely, and then Li Xiao imported the data of the bloodstains and object movement at the scene, and now everyone saw clearly, a virtual portrait appeared in the most dense bloodstains in the house, and the place where this person bleed the most was the neck.

Luo Cheng began to explain to everyone.

"First of all, the suspect came in through the door, the door was intact and there was no sign of being pried, he should have knocked on the door to enter, and after entering the door, he came to the position of the sofa." Saying that, Luo Chengcheng walked to the edge of the sofa, which was also the place with the most dense blood stains. "In this place, the suspect made a move, his murder weapon cut Professor Wan's carotid artery, from the height of the blood, Professor Wan should have been standing at that time, and in the face of the murderer, after being injured, Professor Wan leaned back and fell to the ground with a sofa, his hand scratched on the sofa, leaving scratches, and then he got up and knocked down the coffee table, and the glasses also fell off, at this time, Wei Ling, who was standing by the window, grabbed the lamp and smashed it, but the suspect cleverly dodged, Immediately afterwards, Wei Ling moved her footsteps and equipment to grab the spider plant pot, but she was caught and ripped off a large handful of the spider plant, and then I don't know what happened Her resistance stopped, I guess she should have been chased by the murderer and knocked unconscious, otherwise Professor Wan would not have had time to escape to the bathroom and lock the door. ”

Luo Cheng walked to the door of the bathroom again, and said: "Professor Wan hid in the innermost part of the bathroom, he may have wanted to call for help but was kicked open before he could get the door, and then he was dragged out, he was not dead at that time, his hand scratched on the door and left a bloody handprint, he finally fell down in the corridor, at that time we did not find the second bloodstain route, that is to say, here Professor Wan's bloodstains disappeared, in other words, it was disposed of, it should have been packed with something, such as a trolley box, If the suspect wants to take away the body, he can't just carry the body out, and Professor Wan brought a trolley box when he moved in, and now the trolley box is gone, which shows the problem, the murderer is steady and ruthless, and has a strong sense of anti-reconnaissance, he has processed the shoe prints and fingerprints at the scene, but he is very secret, we extracted some fragmentary apple peels in the garbage basket, and there is just one apple missing in the fruit bowl in the kitchen, and Wei Ling's fingerprints are on the fruit knife, But I searched the whole room and couldn't find the apple core. ”

"You mean Wei Ling ate an apple? Was it before or after the crime? Dai Lin asked.

"It should be that after the incident, the apple peel was very broken, and in some places it was particularly thick, and there were many jagged notches on the edges, which shows that the hands of the apple peelers were shaking very badly, under what circumstances would Wei Ling be so nervous? It should have been coerced, the suspect did not leave in a hurry after killing Professor Wan, but asked Wei Ling to peel an apple for him, and after eating the apple, he lost the apple core in order to destroy the incriminating evidence, which is also the reason why we can't find the apple core. ”

If you kill someone, you can still eat an apple slowly, why is this picture so familiar?

Dai Lin's heart tightened, and said, "You shouldn't say that this case was done by Li Shengyu, right?" ”

"Is it impossible? The murderer is equally ferocious in killing, and he also eats an apple after killing someone, first-class techniques, superb anti-reconnaissance ability, and the two cases do have something in common. Luo Chengdao.

"What about motivation? What was his motive for killing Professor Wan? What is the connection between these two people? Dai Lin really couldn't believe Luo Cheng's words.

Professor Wan did come to Qingzhou to help, and he was on TV on this matter, so it doesn't make sense to kill the killer because of this incident? Is it possible?

"If it's Li Shengyu, that's enough, for him, Zhou Shuyi was caught because of Professor Wan's help, is it Professor Wan or Zhou Shuyi, is there anything wrong with him killing Zhou Shuyi? What can't an extreme person like Lee Seung Woo do? Think about what he said last time, Zhou Shuyi also said that Li Shengyu is a person who will be revenged, and he named me to take revenge on my family, isn't it Professor Wan or Zhou Shuyi in his eyes? From that point of view, it's entirely possible for him to do so. ”

On Qingzhou's side, He Zhonghua called Xie Yusheng to the criminal police team again.

"Did you find it? Did you find Wei Ling? Xie Yusheng couldn't wait to ask.

He Zhonghua was not in a hurry to answer, but poured a glass of water for Xie Yusheng, looking at Xie Yusheng's eager appearance, he really cared about Wei Ling.

"Captain He, what's going on? Wei Ling, did you find it? ”

"You should know about her relationship with Professor Wan, right?" He Zhonghua asked suddenly.

Xie Yusheng was stunned for a moment, smiled bitterly and nodded.

"Yes, you found it?" Xie Yusheng asked.

"Yes, we found out, she didn't go to Shangri-La at all this time, but went to Jinghu Villa, but Professor Wan died."

Xie Yusheng was stunned, lowered his head and his expression became a little bitter, he leaned back in the chair and sighed.

"He should have died a long time ago, he was a liar who took advantage of other people's psychology, I already knew that Wei Ling's relationship with him was not ordinary, but what could I do, I really love her, I don't want to divorce her, I also thought about it, she is still young, and she will naturally come back when she is tired of playing."

Xie Yusheng was not surprised by Professor Wan's death, and even gloated a little.

"Did you find anything unusual when she contacted you these days?" He Zhonghua asked again.

I feel that Luo Cheng and their investigation of Professor Wan should have had an accident for a few days, and Wei Ling only disappeared last night, so something is wrong.

"Yes, she doesn't answer my phone or video, she just says she's inconvenient, which she won't answer the video and phone call even if she lied to me before."

"And how did you get in touch?"

">" Show me. ”

Xie Yusheng hesitated and opened WeChat and handed it to He Zhonghua, He Zhonghua took the mobile phone and immediately found the clue, Wei Ling used to use various expressions when he sent WeChat, and liked to use words like "good" in sentences, which looked more sticky, and the WeChat she sent to Xie Yusheng in the past two days became very brief, and she did not use any punctuation and expressions, and her speech was very blunt, why Xie Yusheng was inconvenient for him to reply at most, and he did not give any explanation.

Such a difference has already explained the problem, and it is obvious that it is not Wei Ling herself who uses Wei Ling's mobile phone.

"Does she have any other requirements than that?"

"Anything else?" Xie Yusheng thought for a while and said: "She asked me to leave a friend's phone number, this person has been engaged in the jade and jade business in Yunnan and Myanmar for a long time, I have done business with him before, and the relationship is good, Wei Ling told me that she wanted to know about jadeite, so I gave her the phone." ”

"Then why don't you have it in WeChat? You deleted it? ”

Xie Yusheng was a little embarrassed, and it took a long time to tell the truth, but in fact, he was afraid that his lover would see this matter and ask him for jade.

"Captain He, Wei Ling won't die too, right?" Xie Yusheng suddenly thought of something.

"No, she's missing, that's why we're here to ask you, and now she's a suspect in the murder of Professor Wan."

"What? How is it possible, I understand her, she doesn't have the courage at all, she won't kill. ”

Xie Yusheng didn't believe that Wei Ling would kill someone, and she didn't have a motive to kill Professor Wan.

After learning more about He Zhonghua, I learned that Xie Yusheng's friend had been traveling back and forth between Myanmar and China for a long time, and many of his jade stones were brought in through smuggling.

In He Zhonghua's opinion, this is smuggling!
