Chapter 195:

274 Chapter 274
At half past ten in the evening, Yu Hanjiang and Xiao Lou came to the crime scene together.
The local police have sent someone to block the scene with a cordon. They only allowed Yu Hanjiang to enter after Yu Hanjiang showed his police officer ’s certificate. The town belongs to the lower units in Binzhou. The policemen at the scene heard that Yu Hanjiang, the captain of the Binzhou Interpol team, actually came over. Everyone was shocked. The murder in the town would have surprised the top boss.
The young criminal police officer in charge of the investigation, Li Xinyang, immediately greeted him, respectfully saying, "Yu team, why would you come here in person?" He glanced at Xiao Lou, and Xiao Lou smiled and stretched out his hand. "Hello Li, I'm Binzhou Forensic Laboratory Xiao Lou. "
The other side politely said, "It was Professor Xiao, but also came with the Yu team?"
Yu Hanjiang simply explained, "We happened to be here today to investigate the case. Xu Kai, the deceased, is related to a murder case being investigated by our city's Interpol. Xiaoli, please sort out the details of the deceased and transfer the case to me."
Li Xinyang nodded. "Good Yu team, you go to the scene first ... this scene is a bit weird."
Yu Hanjiang put on his gloves and followed Li Xinyang upstairs.
Yu Hanjiang and Xiao Lou followed Captain Li into the scene of the crime. The two accidentally discovered that Xu Kai's death scene was very similar to Lin Yiyan's death scene.
However, Xu Kai should have been murdered while bathing, and he was not wearing clothes.
He was lying in the bathtub, his eyes widened in horror, and there were marks of being cut across his body, and his body was also full of ice cubes, except that Xu Kai's room was heated, so part of it The ice cubes have melted.
The water melted by the ice cubes was mixed with the blood of the deceased. The water in the entire bathtub became blood red. Xu Kai was lying in this water, and he did not stare. This scene was really shocking.
Li Xinyang said, "We have just arrived at the scene. It is the case of Xu Kai's cousin Zhang Xiaoyu."
He turned his gaze to the side and pointed Yu Hanjiang to the position of Zhang Xiaoyu.
The Zhang Xiaoyu, also the manager of "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 trembling. After seeing him, Yu Hanjiang winked at Xiao Lou, and whispered in Xiao Lou's ear, "You can check the corpse first. I'll go to the reporter and ask the situation."
Xiao Lou nodded his head, put on his gloves, and leaned over to start examining the body.
In the bathtub, the corpse was soaked with puffiness. This time, the murderer was still very dense after the crime. The blood on the surrounding walls was wiped clean. There was no trace of blood splashing. All the blood flowed into the bathtub. in.
Xiao Lou opened the water valve under the bathtub and let out most of the blood and water, so that the whole body was exposed, and then he began to examine carefully. Next, the town's forensic doctor consciously handed him the toolbox. Some young trainee criminals probably did not see such a disgusting scene, ran downstairs and vomited, and Li Xinyang gave him a stern glance.
Xiao Lou suddenly said, "Give me a pair of tweezers."
The forensic doctor nearby assisted him and immediately passed him the clean tweezers.
Xiao Lou clipped a long hair out of the bathtub and put it in a sterile sealed bag for storage. Whether the long hair was left by the murderer, he can't judge at this time, but the evidence found on the scene must always be brought back for careful inspection.
There were not many clues on the deceased. The killing method was similar to the case of Lin Yiyan. The fatal wounds were in the heart. However, the wound was not the same as that of Lin Yiyan. Xiao Lou held up the dead body and looked at his Behind, my heart was clear.
The deadly wound of the deceased was in the heart like Lin Yiyan, but Lin Yiyan's wound was penetrated from the front, while Xu Kai's wound was penetrated from the back. Therefore, the wound will appear wide on the back and the front heart Relatively narrow phenomenon.
Xiao Lou carefully examined the body. Yu Hanjiang turned around at the scene and came to the reporter Zhang Xiaoyu, asking "when did you come to your cousin's house and found his body?"
Zhang Xiaoyu said "at ten or ten in the evening."
Yu Hanjiang asked, "Did you have any contact with your cousin after two o'clock this afternoon?"
Zhang Xiaoyu nodded. "At about six o'clock in the evening, I called him, but he didn't answer. I thought he went to the ktv club to find him again, so he ignored him."
Yu Hanjiang "Then why did you come to him suddenly at ten in the evening?"
Zhang Xiaoyu said, "I want to ask him to borrow a little money. I have a tight hand recently. I want to try his luck at his house."
Yu Hanjiang asked sharply, "He was dead then, how did you get in?"
Zhang Xiaoyu hurriedly explained, "I have the keys to his house, because my brother sometimes goes to talk business outside the house. The fish and flowers raised in the house are not taken care of. I live nearby, so he gave me the keys. Let me sit back and take care of him. "
Yu Hanjiang nodded his head and said, "Did you see a suspicious person in the neighborhood when you came in? Or a vehicle?"
Zhang Xiaoyu thought for a while, shook his head and said, "No, I, I didn't pay attention."
When the cousin answered the question, he never dared to look at Yu Hanjiang's eyes, his expression flustered, his eyes dodging from side to side, obviously a guilty conscience. He may have concealed something, but Yu Hanjiang did not think he had a direct relationship with the murder of Xu Kai.
After the trial of Zhang Xiaoyu, Yu Hanjiang returned to Xiao Lou and asked in a low voice, "What was the result of the autopsy?"
Xiao Loudao "The deadly wound of the deceased is still the heart part. A sharp long knife pierced his heart directly. From the marks of the wound, the murder weapon should be the same as the long knife that killed Lin Yiyan. Others on his body Knife marks should be left after death. "
Yu Hanjiang frowned. "In other words, after the murderer killed him, he whip him again?"
Xiao Lou nodded "as in the case of Lin Yiyan."
He lifted the body's head up, examined the pupils and corpses on his body carefully, and said, "From the perspective of corpses and muscle stiffness, the time of death should be about 6 hours."
Yu Hanjiang looked at the wall clock in the bedroom.
The current time is 22:35, and the death time is about four hours. That is to say, Xu Kai's death time should be around 16:30 in the afternoon. And Yu Hanjiang and Xiao Lou left Xu Kai's house at exactly 4:30.
Realizing this, they both felt creepy!
In other words, as soon as they left, Xu Kai was brutally killed in the bathroom by the murderer.
Yu Hanjiang took a deep breath and lowered his voice in Xiao Lou's ear. "When we interrogated Xu Kai, it was likely that the murderer had sneaked into Xu Kai's residence and was ready to murder Xu Kai. However, she hid in In the corner, we failed to find out. "
Xu Kai's villa has a basement, a living room, dining room and garden on the first floor, a master bedroom and a study on the second floor, several guest bedrooms on the third floor, and a rooftop on the fourth floor.
A villa of this size is hidden by one person, and it is really not easy to find it if it is not carefully searched.
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, and Qu Wanyue and his teammates were staring at her, they did not expect that the murderer would commit another crime and came to murder Xu in advance Kai. Therefore, at that time, they did not conduct a detailed search of Xu Kai's residence.
What's more, searching the residence of the residents requires a "search warrant" approved by the superior.
For example, Zhou Yuanyuan has a very strong motivation to commit crimes and can only be searched after being locked as a suspect.
Xu Kai is only an insider of Lin Yiyan's case, not a suspect. The search warrant will not be easily approved. Even Yu Hanjiang, even a police officer, 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 inquiry about Xu Kai.
I still remember when the two came to Xu Kai's house, Xu Kai had just woke up and should have been awakened by Yu Hanjiang's continuous doorbells. He walked down from the bedroom to the living room, sleepy eyes, and his hair went into the bird's nest. No washing.
It can be imagined that after Yu Hanjiang and Xiao Lou left, Xu Kai's first thing to do was to take a bath.
His cousin Zhang Xiaoyu mentioned that he returned home drunk last night. It is normal for a hangover to take a bath in the bathtub to wake up. He walked into the bathroom, took off his robe, and was ready to bathe in water.
Unexpectedly, at this moment, the murderer who had been hiding in the villa suddenly took out a sharp long knife, and stabbed him through the heart!
Xiao Lou pointed at the corpse and said, "Unlike the Lin Yiyan case, this time, Xu Kai's heart part was penetrated from the back. The murderer attacked from behind him and killed him in one shot."
Yu Hanjiang nodded. "After all, the killer is likely to be a woman. If she fights against a tall and sturdy man like Xu Kai, she may not be able to take advantage. At that time, Xu Kai was undressed and was going to take a shower. It should be more lax and sneak attack from behind, Xu Kai is also very difficult to prepare for. "
After all, no one would think that a person was hidden in his bathroom!
No wonder Xu Kai's eyes were as wide as the size of a copper bell, and the eyes almost fell out. Apparently, he was about to step into the bathtub at the time, but was stabbed from behind, looking at the sharp blade that pierced his chest, he must be extremely shocked.
Captain Li carefully listened to the conversation between them, his face blanked.
Yu Hanjiang suddenly said, "Are there any luminescent ammonia?"
Li Xinyang immediately said, "Bring it, Xiaoqi, you can bring it to the Yu team."
A young police officer immediately walked over and brought luminous ammonia to Yu Hanjiang. Yu Hanjiang opened the equipment and surveyed the scene carefully. Although the killer had cleared the blood, the luminous component of luminous ammonia could show the blood.
Even if the blood stains are 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 large number of blue-purple 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 is here. He was stabbed by the murderer, and blood splattered on the wall. Xu Kai struggled for a while, and soon died. Then, the murderer took his The body moved into the bathtub, surrounded him with ice, and whip him. "
Li Xinyang heard the hair on his back. "This ... how much hatred it is!"
Yu Hanjiang said, "The murderer in this case has been distorted. Moreover, she is very clever and can lurk in the target's home in advance and kill the target unexpectedly. I guess she may have learned the unlocking technique, otherwise it is difficult to explain How she continued to lurk to Lin Yiyan's and Xu Kai's. "
Mysteriously sneaked into the target's home, and then stabbed each other while the other was taking a shower ...
This killer is simply not lost to a professional killer!
Chapter 275
Yu Hanjiang and Xiao Lou came to the following conclusions after autopsy.
First, the murderer's time was determined to be around 4:30 pm, and they committed the crime immediately after they left, probably because they were afraid of night long dreams and were arrested by the police. After she committed the crime, she definitely drove away. At present, she needs to find the vehicles at the gate of the community property to check the entrance and exit of the vehicle.
Second, the murderer has a soft spot for ice cubes, and the burial of the body with ice cubes at the scene of the crime seems to have a strange allegory, much like "curses" and the like. She killed Lin Yiyan and Xu Kai in succession, and vented his wrath after the killing. At present, the most motivated and suspected person is Qiao Xuening.
But, which is the real Qiao Xuening? Yu Hanjiang and Xiao Lou looked at each other with a little confusion in their hearts.
Yu Hanjiang Shen said, "I performed a carpet search of the entire villa, and I don't believe she would not leave any clues."
The two searched from the basement to the attic on the balcony, collected all fingerprints and hair appearing in the villa, and also found a plum-shaped earring on the attic, which were sealed back by Xiao Lou with a sterile bag.
That night, Xiao Lou temporarily borrowed the town's forensic appraisal center to appraise the evidence collected at the scene, while Yu Hanjiang went to the property for detailed monitoring.
The two worked separately until the police station merged at three in the morning.
Xiao Lou compiled all the identification results to Yu Hanjiang to see "the long hair found in the bathtub. After comparing the gene bank, it belongs to a girl named Lin Dandan."
Li Xinyang said, "I know this Lin Dandan, it is a girl who accompanies wine in our small town ktv. She is very beautiful and has long hair. She should be dating Xu Kai for a while."
Xiao Lou then asked "What about Liu Qi, Yue Qingqing?"
Li Xinyang said, "They are all Xu Kai's girlfriends."
He rubbed his temples with a bitter smile, and introduced them to Xu Kai's situation in recent years. According to Li Xinyang, Xu Kai is still unmarried, and he is still handsome in his thirties. In addition, he is also a big boss of Internet cafes and two hot pot cities. He is particularly rich and has become a "head snake" in this town The same existence.
Xu Kai is the fifth single diamond king. The girls chasing him must be in a long line. He basically changes a girlfriend for half a year and will give the girls a lot of money when they break up. So although his private life is chaotic, there should be no girls because Break up with him and kill him.
Li Xinyang said,
Xu Kai ’s comments are not very good, but he is quite generous in dealing with his lover. Many people in our town know that he will give each other enough money when he breaks up with each girlfriend, and the other party will also Take money away with pleasure. Professor Xiao, the three you mentioned just now are girlfriends he has been dating in the past year. "
Xiao Loudao "It seems that I guessed right. The hair and fingerprints from the basement, kitchen and bathtub were all left by Xu Kai's girlfriends. Obviously, he would take his girlfriend home for the night."
Yu Hanjiang frowned slightly. "It's not these people who killed him."
Li Xinyang froze and said, "How are you sure of the Yu team?"
Yu Hanjiangdao "He is related to the murder we are investigating. The ice on the scene is exactly the same, the killing methods are the same, and even the weapon is the same. Therefore, this must be a serial killing case made by the same murderer. In your town These girls who have been with him are not too suspicious. Tomorrow you will call them all for questioning. If you can prove that they are not present, let them go. "
Li Xinyang was relieved and said, "OK."
Yu Hanjiang patted the young captain's shoulder. "It's hard. Go back first. Let's talk at dawn."
After leaving the police, Yu Hanjiang and Xiao Lou drove back to the hotel together.
It was already four o'clock in the morning when I got back to the room. Yu Hanjiang squeezed his eyebrows. I watched all the surveillance videos on the Xiaolou Road. From 4pm to 10pm, there were 30 vehicles in and out of the community. I have all recorded it. In addition, no suspicious person similar to Qiao Xuening was found. "
Xiao Loudao "Sleep for a while, tomorrow we will check the traffic police team."
The two fell asleep each other, and only got up after a few hours of sleep.
At seven o'clock the next morning, Yu Hanjiang called Qu Wanyue first and told him, "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, "Rest assured, I will find an excuse to teach her dance moves, and stay with her all day to watch her film."
Yu Hanjiang hung up the phone, and Xiao Lou came to the traffic police team to check the owner's information.
After 4 pm yesterday, none of the vehicles leaving the villa area were suspicious. All the owners could find people, all of them were residents of this town. The town's criminal police captain Li Xinyang also checked and found them in turn. data of.
Some go to the supermarket to buy food, some go to eat with their family ...
Even all the cars have other people who can prove that without a car, the driver left alone.
Yu Hanjiang frowned thoughtfully. "She didn't drive away? It seems she is very cautious, fearing that we can find her real information when we check the license plate number, it is likely that she left the villa area on foot."
Xiao Lou agreed with "The case of Lin Yiyan. She drove Lin Yiyan's car and could not find her own vehicle. This time, she simply did not drive and could leave on foot. There should be only one exit in the community and she should be able to take pictures. Is she right? "
Yu Hanjiang Road "But none of the people who came in and out of the community yesterday afternoon were like Lin Yiyan."
Xiao Lou thought about it and said, "Will she run away from the wall?"
Yu Hanjiang nodded. "It's possible. Although the fence of the villa area is relatively high, if she can climb trees, there are many places to go over the wall. I have let the property monitor all the locations in my community. Let's check it today. "
Yu Hanjiang and Xiao Lou went to the police together.
Li Xinyang invited Xu Kai's girlfriend in the early morning.
All three had a full absence certificate, some sang at ktv, some permed at the barber shop yesterday afternoon, and the third had three girlfriends shopping yesterday afternoon, all of which were confirmed.
After Li Xinyang made a simple note, he released the three.
When Yu Hanjiang and Xiao Lou came over, he told the Yu team the result. Yu Hanjiang had already expected it, so he was not disappointed. After all, the case of Xu Kai and Lin Yiyan is a serial case. The hair of these girlfriends found in the villa cannot help the progress of the case at all.
Xiao Lou said with regret, "The hair and fingerprints found are all interference items."
Yu Hanjiang frowned. "The murderer has gained experience in the crime. She may have wrapped her tightly and put on gloves, so she will not leave any information that can be checked for fingerprints and genes. Her ice cubes should be made on-site. . "
Apparently, the murderer sneaked into Xu Kai's room in advance, while Xu Kai was sleeping, made a lot of ice cubes in the freezing layer of his refrigerator, and then unexpectedly killed Xu Kai, buried the body with ice cubes, and took away the refrigerator. Container.
In this way, the ice in the Lin Yiyan case can also be explained. The murderer also lurked in Lin Yiyan's home in advance and made a lot of ice cubes on the spot with her refrigerator. After killing Lin Yiyan, she also took away the box made with ice cubes, causing police to question the source of the ice cubes.
Yu Hanjiang said, "Let's look at surveillance first."
Captain Li Xinyang also took the initiative to help and called colleagues to open the surveillance video of the entire villa community of the property. Each person was in charge of an area and looked at the monitoring in detail.
Everyone has been busy all day ...
However, no one was found climbing out of the community.
Li Xinyang wondered, "I didn't drive away or climb the wall. Can the killer fly? Or will he dig?"
Xiao Lou also looked at Yu Hanjiang in confusion. "The same is true of the case of Lin Yiyan. We have checked from beginning to end in the past few days. There is no suspicious vehicle entering, unless she is airborne or drilling into the community from the ground. Explain? "
In the case of Lin Yiyan, since Lin Yiyan rarely returned to Yuehu Villa, if the murderer sneaked in half a month ago, monitoring would be difficult to detect. The murderer left Lin Yiyan's car when he left.
But Xu Kai's case is different.
Xu Kai went home every day. The murderer could not have been hidden in his house for too long. At most, when he went out to drink last night, the murderer sneaked into the villa. Today, he prepared everything to kill Xu Kai and left. Monitoring is easy to investigate.
However, no trace of the killer entering and leaving the community was found in the surveillance.
How did the murderer enter the villa complex where Xu Kai lives? How did you leave?
Does the killer really fly? !!
This is not a martial arts script, the murderer will never fly out with light effort.
Xiao Louzheng was puzzled and suddenly heard Yu Hanjiang said, "I'm afraid we have fallen into a misunderstanding from the beginning."
Xiao Lou looked at him in confusion "What does Yu mean?"
Yu Hanjiang said, "The murderer didn't hide. She walked in and went out."
Xiao Lou was surprised.
"Cosmetology." Yu Hanjiang looked at Xiao Lou and whispered "Since someone is plasticizing Qiao Xuening, Qiao Xuening may also be plastic."
Therefore, Qiao Xuening could not be found in the monitoring.
Because she has changed her face!
