【Chapter 274, True and False Stand-in】
At 10:30 in the evening, Yu Hanjiang and Xiao Lou came to the scene of the crime together.
The local police have sent people to cordon off the scene. They let Yu Hanjiang enter after Yu Hanjiang showed the police officer's ID. The town belongs to a subordinate unit of Binzhou City. The criminal police at the scene, I heard that the captain of Binzhou Interpol actually came here in person. Everyone was shocked. Unexpectedly, the murder in the small town would shock the top boss.
Li Xinyang, a young criminal police officer in charge of investigating the case, greeted him immediately and respectfully said: "Team Yu, why did you come here in person?" He glanced at Xiao Lou, and Xiao Lou smiled and stretched out his hand: "Hello, team Li, I am a forensic doctor in Binzhou City. Xiao Building of the Appraisal Center."
The other party said politely, "So it's Professor Xiao who is also coming with Team Yu?"
Yu Hanjiang briefly explained: "We happened to come to investigate the case today. The deceased Xu Kai is related to a murder case being investigated by our city's criminal police team. Xiao Li, please sort out the details of the deceased and transfer the case to me. "
Li Xinyang nodded: "Okay, Team Yu, you go to the scene first... This scene is a bit weird."
Yu Hanjiang put on his gloves and simply followed Li Xinyang upstairs.
Yu Hanjiang and Xiao Lou followed Captain Li into the scene of the crime. The two unexpectedly discovered that Xu Kai's death scene was very similar to Lin Yiyan's death scene.
It's just that Xu Kai should have been murdered while taking a shower, without any clothes on.
He lay in the bathtub, his eyes widened in horror, his whole body was covered with traces of being cut by a knife, and there were also ice cubes around him, except that Xu Kai’s room had a heater turned on, so, partly The ice cubes have melted.
The water melted from the ice cubes mixed with the blood on the deceased's body, and the water in the entire bathtub turned blood red. Xu Kai was lying in this bloody water and staring at him. This scene was really shocking.
Li Xinyang said: "We have just come to the scene, and it is the case of Zhang Xiaoyu, Xu Kai's cousin."
He shifted his gaze to the side and pointed to Yu Hanjiang the location of Xiaoyu Zhang.
This Zhang Xiaoyu, the manager of the "Whale Internet Cafe", Yu Hanjiang and Xiao Lou met him today. At this moment, he was holding his head, sitting on the bed next to him shivering. After seeing him, Yu Hanjiang winked at Xiao Lou, and whispered in Xiao Lou's ear: "You can do an autopsy first. I'll go to the reporter to ask about the situation."
Xiao Lou nodded, put on his gloves, and leaned over to examine the corpse.
In the bloody bathtub, the body was soaked that it was a little puffy. This time, after the murderer committed the crime, it was still very meticulous. The blood on the surrounding walls was wiped clean. There was no trace of blood splashing. All the blood flowed into the bathtub. inside.
Xiao Lou opened the water valve under the bathtub and drained most of the blood, so that the whole body was exposed, and then he began to check carefully. Next to him, the forensic doctor in the small town consciously handed him the toolbox. Some young interns probably had never seen such a disgusting scene. They ran downstairs and vomited, but Li Xinyang gave him a fierce look.
Xiao Lou suddenly said, "Give me a pair of tweezers."
The forensic doctor next to him served as his assistant and immediately handed him the clean tweezers.
Xiao Lou took out a long hair from the bathtub and put it in a sterile airtight bag for preservation. Whether this long hair was left by the murderer or not, he still can't judge at present, but the evidence found on the spot always has to be brought back for careful examination.
The deceased’s body didn’t have many clues. The killing technique was similar to that of Lin Yiyan’s case. The fatal wounds were all located in the heart, but the wounds were not the same as those of Lin Yiyan’s. Xiao Lou lifted the deceased’s body and checked his Behind, my heart is clear.
The fatal wounds of the deceased were in the heart just like Lin Yiyan, but Lin Yiyan’s wound was pierced from the front, while Xu Kai’s wound was pierced from the back. Therefore, the scars would appear wide on the back and the mouth on the front. A relatively narrow phenomenon.
Xiao Lou conducted a careful inspection of the corpse. Yu Hanjiang walked around the scene and came to the reporter Zhang Xiaoyu. He asked: "When did you come to your cousin's house and found his corpse?"
Zhang Xiaoyu tremblingly said: "Ten or ten o'clock in the evening."
Yu Hanjiang asked: "Have you contacted your cousin after two o'clock this afternoon?"
Zhang Xiaoyu nodded: "I called him at about six o'clock in the evening, but he didn't answer it. I thought he was going to the KTV club to find his friend, so I ignored him."
Yu Hanjiang: "Then why did you come to him suddenly at ten o'clock in the evening?"
Zhang Xiaoyu said, "I want to borrow some money from him. I have a tight hand recently. I want to come to his house and try my luck."
Yu Hanjiang asked sharply, "He was already dead, how did you come in?"
Zhang Xiaoyu hurriedly explained: "I have the key to his house, because my brother sometimes goes out to discuss business. The fish and flowers raised at home are not taken care of by anyone. I live nearby, so he gave me the key. , Let me take time to take care of him."
Yu Hanjiang nodded, and said, "Did you see any suspicious people in the community when you came in? Or was it a vehicle?"
Zhang Xiaoyu thought about it for a while, shook his head and said, "No, I, I didn't pay attention."
When this cousin answered the question, he had not dared to look at Yu Hanjiang's eyes. He was flustered and dodged his eyes, obviously with a guilty conscience. He may have concealed something, but Yu Hanjiang does not think he is directly related to the murder of Xu Kai.
After Zhang Xiaoyu's trial, Yu Hanjiang returned to Xiao Lou and asked in a low voice: "How was the autopsy result?"
Xiao Lou said: "The fatal wound of the deceased is still the part of the heart. A sharp long knife directly pierced his heart. Judging from the wound marks, the weapon should be the same as the long knife that killed Lin Yiyan. Other knife marks should be left after death."
Yu Hanjiang frowned: "In other words, after the murderer killed him, he whipped him again?"
Xiao Lou nodded: "It's the same as the Lin Yiyan case."
He lifted the head of the corpse, carefully checked the pupils and the plaques on his body, and said: "From the perspective of the plaques and muscle stiffness, the time to death should be about 6 hours."
Yu Hanjiang looked at the wall clock on the wall in the bedroom.
The current time is 22:35, and the time of death is about four hours, which means that Xu Kai's death time should be about 16:30 in the afternoon. And the time when Yu Hanjiang and Xiao Lou left Xu Kai's house was exactly 4:30.
Realizing this, both of them felt terrified!
In other words, as soon as the two of them left, Xu Kai was brutally killed in the bathroom by the murderer on the back foot.
Yu Hanjiang took a deep breath, lowered his voice and said in Xiao Lou's ear: "When we interrogated Xu Kai, it is very likely that the murderer had already sneaked into Xu Kai's residence and was ready to murder Xu Kai. However, she was hiding. In the corner, we couldn't find it."
Xu Kai’s villa has a basement, the living room, dining room and garden on the first floor, the master bedroom and study on the second floor, several guest bedrooms on the third floor, and a rooftop on the fourth floor.
There is a person hidden in such a big villa, and it is really not easy to find if you don't search carefully.
When Yu Hanjiang and Xiao Lou came to investigate him, because the current suspect, Qiao Xuening, was filming in the crew of Binzhou Film City, Qu Wanyue and other teammates were staring at her. Neither of them expected that the murderer would commit the crime again and came to murder Xu in advance. Kai. Therefore, they did not conduct a detailed search of Xu Kai's residence at that time.
What's more, to search the residences of residents requires a "search warrant" approved by the superior.
For example, Zhou Yuanyuan had a very strong motive for committing crimes, and could only be searched after being locked as a criminal suspect.
Xu Kai is only an insider of Lin Yiyan's case, not a criminal suspect. The search warrant will not be issued easily. Even if Yu Hanjiang is a policeman, he cannot search people's homes casually.
At that time, the murderer was probably hiding in Xu Kai's home, and maybe he heard Yu Hanjiang's question to Xu Kai.
I still remember that when the two came to Xu Kai’s house, Xu Kai just woke up. He should have been awakened by Yu Hanjiang’s continuous doorbell. He walked directly from the bedroom to the living room, sleepy eyes and messy hair into the bird’s nest. It was obvious at that time No washing.
It is conceivable that after Yu Hanjiang and Xiaolou left, Xu Kai's first thing to do is to take a bath.
His cousin Zhang Xiaoyu once mentioned that he came home drunk last night. It's normal for people with hangovers to take a bath in the bathtub to sober up. He walked into the bathroom, took off his robe, and prepared to take a shower.
Unexpectedly, at this moment, the murderer who had been hiding in the villa suddenly took out a sharp long knife and stabbed him in the heart!
Xiao Lou pointed to the corpse and said: "The difference from Lin Yiyan's case is that this time, Xu Kai's heart wound was pierced from behind, and the murderer attacked from behind him, killing him with one blow."
Yu Hanjiang nodded: "After all, the murderer is likely to be a woman. If you fight head-on with a tall and muscular man like Xu Kai, she may not be able to take advantage. At that time, Xu Kai took off his clothes and was about to take a bath. Jing should be relatively lax, and Xu Kai is also very difficult to guard against a sneak attack from behind."
After all, no one would have thought that there was someone hiding in his bathroom!
No wonder Xu Kai's eyes were as wide as a copper bell, almost falling out. Obviously, he was just about to step into the bathtub, and he was stabbed from behind. He must have been shocked by the sharp point of the knife that pierced his chest.
Captain Li listened carefully to the conversation between the two, with a dazed expression on his face.
Yu Hanjiang suddenly said: "Do you have luminol?"
Li Xinyang said immediately: "Take it, Xiao Qi, you can bring it to Team Yu."
A young police officer immediately walked over and brought luminol to Yu Hanjiang's hands. Yu Hanjiang turned on the equipment and inspected the scene carefully. Although the murderer had cleaned up the blood stains, luminol, a component of luminol, could show blood stains.
Even if the blood stain is wiped and cleaned up by the murderer, the hemoglobin in the blood will still remain. When the luminol reagent is sprayed on the hemoglobin, it will oxidize with active oxygen and release blue-violet fluorescence.
Yu Hanjiang sprayed it in the bathroom, and soon, a lot of blue-violet fluorescent traces appeared on the walls and the ground.
Xiao Lou looked at the most fluorescent part and walked to this position and said: "Xu Kai was here, stabbed back by the murderer, and blood splashed on the wall. Xu Kai struggled for a while and died soon, and then the murderer killed him Moved his corpse into the bathtub, surrounded him with ice cubes, and whipped him."
Li Xinyang heard the hair on his back: "This... what a hatred this is!"
Yu Hanjiang said: "The murderer of this case has been distorted. Moreover, she is very smart and can lurk to the target's home in advance and kill the target unexpectedly. I guess she may have learned the skill of unlocking, otherwise it will be difficult. Explain how she lurked to Lin Yiyan's house and Xu Kai's house continuously."
The secret sneaked into the target's home, and then stabbed him to death while he was in the bath...
This murderer is no less than a professional killer!
*************
【Chapter 275, True and False Stand-in】
After an autopsy, Yu Hanjiang and Xiao Lou came to the following conclusions.
First, the time for the murderer to commit the crime was determined to be around 4:30 in the afternoon. They committed the crime immediately after they left, probably because they were afraid that the night would have a lot of dreams and would be caught by the police. She must have drove off after committing the crime. Currently, she needs to find the property of the community to check the entrance and exit of vehicles.
Second, the murderer has a special liking for ice, and burying the body with ice at the crime scene seems to have a strange meaning, much like a "curse" or something. She successively killed Lin Yiyan and Xu Kai, and vented her anger and whip the corpse after the murder. At present, the person with the greatest motive and suspicion is Qiao Xuening.
But, which one is the real Qiao Xuening? Yu Hanjiang and Xiao Lou looked at each other, feeling a little confused in their hearts.
Yu Hanjiang said solemnly: "I did a carpet search of the entire villa, and I don't believe that she won't leave any clues."
The two searched all the way from the basement to the attic on the balcony, collected all the fingerprints and hair that appeared in the villa, and also found a plum-shaped earring on the attic, which was sealed by Xiaolou in a sterile bag and brought back.
That night, Xiao Lou temporarily borrowed the town’s forensic appraisal center to appraise the evidence collected on the spot, while Yu Hanjiang went to the property to check the monitoring in detail.
The two were working separately, and the police station did not meet until three o'clock in the morning.
Xiao Lou sorted out all the identification results to Yu Hanjiang: "The long hair found in the bathtub, after comparing the gene bank, belongs to a girl named Lin Dandan."
Li Xinyang said, "I know that Lin Dandan is a girl who accompanies the wine in our small town KTV. She is very beautiful and has long hair. She should have been dating Xu Kai for a while."
Xiao Lou then asked: "Then Liu Qi, where is Yue Qingqing?"
Li Xinyang said: "They are all Xu Kai's girlfriends."
He rubbed his temples with a wry smile, and introduced Xu Kai's situation in detail to the two of them in recent years. According to Li Xinyang, Xu Kai is unmarried so far. He is still handsome in his thirties. In addition, he is also the big boss of Internet cafes and two hot pot cities. He is especially rich and has become a "snake" in this small town. The same exists.
Xu Kai is a single diamond king. The girls who chase him have to line up. He changed a girlfriend in the first half of the year and would give girls a lot of money when he broke up. So although his private life is chaotic, there should be no girls because of it. Break up with him and kill him.
Li Xinyang said: "Xu Kai's reputation is not very good, but he is generous in dealing with lovers. Many people in our town know that when he breaks up with every girlfriend, he will give each other enough money, and the other Will take the money and leave happily. The three you mentioned, Professor Xiao, are all girlfriends he has been with in the past year."
Xiao Lou said: "It seems I'm right. The hair and fingerprints found in the basement, kitchen, and bathtub are all left by Xu Kai's girlfriends. Obviously, he will take his girlfriend home for the night."
Yu Hanjiang frowned slightly: "It was not these people who killed him."
Li Xinyang was startled, and said, "How are you sure about Team Yu?"
Yu Hanjiang said: "He is related to the murder we are investigating. The ice at the scene of the crime is exactly the same, the murder method is the same, and even the murder weapon is the same. Therefore, this must be a serial murder case made by the same murderer, your town The girls who have been with him are not very suspicious. Tomorrow you call them all over for interrogation. If you can provide an alibi, let them go."
Li Xinyang breathed a sigh of relief and said, "Okay."
Yu Hanjiang patted the young captain on the shoulder: "Thanks for your hard work, let's go back first, let's talk about it after dawn."
After leaving the police force, Yu Hanjiang and Xiao Lou drove back to the hotel together.
When he returned to his room at four in the morning, Yu Hanjiang pinched his eyebrows and said, "I watched all the surveillance videos of the community. Between 4 pm and 10 pm, there are a total of 30 vehicles entering and leaving the community, with license plates. I have recorded all the numbers. Besides, no suspicious person similar to Qiao Xuening was found."
Xiao Lou said, "Sleep for a while, and we will check on the traffic police team tomorrow."
The two went to sleep separately, and got up after only a few hours of sleep.
At 7 o'clock the next morning, Yu Hanjiang first called Qu Wanyue and told: "Qiao Xuening must keep an eye on her, don't let her run away. When Xiao Lou and I come back, we can find out her details."
Qu Wanyue said: "Don't worry, I will find excuses to teach her dance moves, and stay with her all day to watch her filming."
Yu Hanjiang hung up the phone and came to the traffic police team to check the owner's information with Xiao Lou.
After four o’clock in the afternoon yesterday, none of the vehicles that left the villa area were suspicious. All the owners could find people. They were all residents of this small town. The detective captain Li Xinyang of the small town also checked and found them in turn. data of.
Some go to the supermarket to buy groceries, some go to dinner with their families...
Even all the cars have other people who can prove that none of the cars was driven away by the driver alone.
Yu Hanjiang frowned thoughtfully: "She didn't drive away? It seems that she is very cautious, afraid that we will find out her true information by checking the license plate number. It is very possible that she left the villa area on foot."
Xiao Lou agreed: "In the case of Lin Yiyan, she drove Lin Yiyan's car and could not find her own car. This time, she didn't drive at all, and if she could leave on foot, there is only one exit in the community, which should be able to take pictures. Isn't it right for her?"
Yu Hanjiang said: "But none of the people who entered or left the community yesterday afternoon were like Lin Yiyan."
Xiao Lou thought about it carefully, and said, "Did she escape over the wall?"
Yu Hanjiang nodded: "It is possible that although the fence of the villa area is relatively high, if she can climb trees, there are many places where she can climb over the walls. I have asked the property to provide me with monitoring of all locations in the community. Today we will continue to check. Bar."
Yu Hanjiang and Xiao Lou went to the police team together.
Li Xinyang invited Xu Kai's previous girlfriends over early in the morning.
All three have sufficient alibi, some sang with others in KTV, some permed their hair in the barber shop yesterday afternoon, and the third one made an appointment with three girlfriends to go shopping yesterday afternoon, all of which can be confirmed.
After Li Xinyang simply made a transcript, he released the three of them.
When Yu Hanjiang and Xiao Lou came over, he told Team Yu the result. Yu Hanjiang had expected it a long time ago, so he was not disappointed. After all, the Xu Kai case and the Lin Yiyan case are serial cases, and the hair of the girlfriends found in the villa cannot help the progress of the case.
Xiao Lou said with some regret: "The hair and fingerprints found in the search seem to be interference items."
Yu Hanjiang frowned and said: "The murderer has gained experience in committing the crime. She may be wrapped tightly all over, wearing gloves, so she will not leave any information that can be used to verify fingerprints and genes. Her ice cubes should be made on site. of."
Obviously, the murderer sneaked into Xu Kai's room in advance, made a lot of ice cubes in the freezing layer of his refrigerator while Xu Kai was sleeping, then unexpectedly killed Xu Kai, buried the body with ice cubes, and took away from the refrigerator. Container.
In this way, the ice cubes in Lin Yiyan's case can also be explained. The murderer also lurked in Lin Yiyan's house in advance and used her refrigerator to make a lot of ice cubes on the spot. After killing Lin Yiyan, she also took away the ice box, making the police question the source of the ice.
Yu Hanjiang said: "Let's look at the surveillance first."
Captain Li Xinyang also took the initiative to help, called his colleagues, opened the surveillance video of the entire villa community provided by the property, and each was responsible for an area to check the surveillance in detail.
Everyone has been busy all day...
However, no one was found to have climbed the wall out of the community.
Li Xinyang looked puzzled: "I didn't drive away, nor climbed out of the wall. Could the murderer fly? Or would he burrow?"
Xiao Lou looked at Yu Hanjiang suspiciously: "The same is true of the Lin Yiyan case. We have checked from start to end during the monitoring of those days. No suspicious vehicle entered. Unless she was airborne or drilled into the community from the ground, she should How to explain it?"
In the case of Lin Yiyan, because Lin Yiyan seldom returns to Yuehu Villa, if the murderer sneaked in half a month ago, it would be difficult for surveillance to find out. The murderer drove Lin Yiyan's car when he left.
But Xu Kai's case is different.
Xu Kai went home every day. The murderer could not hide in his house for too long. At most, when he went out for a drink last night, the murderer sneaked into the villa. Today, he made all preparations to kill Xu Kai and leave, no more than 24 hours. Monitoring is very convenient for investigation.
However, no trace of the murderer could be found in or out of the community in the surveillance.
How did the murderer enter the villa complex where Xu Kai lived? How did you leave again
Could the murderer really fly? !
This is not a martial arts drama, the murderer will not fly out easily.
Xiao Louzheng was puzzled and suddenly heard Yu Hanjiang's words: "I'm afraid, we got into a misunderstanding of thinking from the beginning."
Xiao Lou looked at him suspiciously: "What does Yu team mean?"
Yu Hanjiang said: "The murderer didn't hide, she walked in and walked out in an open manner."
Xiao Lou was very surprised.
"Plastic surgery." Yu Hanjiang looked at Xiao Lou and whispered: "Since someone has a plastic surgery to be Qiao Xuening, then Qiao Xuening may also have a plastic surgery to look like someone else."
Therefore, Qiao Xuening could not be found in the monitoring.
Because she has changed her face!
