"Where did you get the ethanol you used to commit the crime?" Xu Lang continued to ask.

"Advisor Xu, have you forgotten what I do?" Xue Sheng looked at Xu Lang and asked rhetorically.

Xu Lang remembered that Xue Sheng had learned tattoos before, and found a small tattoo machine in the room of 301, and in the room with the formalin tongue, there were also many pictures of tattoos, and those who did tattoos needed anesthesia, and ethanol was naturally an indispensable thing, so Xu Lang asked: "But we didn't find ethanol in your room, where did you hide the ethanol?" ”

"I still have a place to live on Fenghua Road, and everything is hidden there."

Xue Sheng said his other residence on Fenghua Road, and Wu Yong, who was standing outside the interrogation room, immediately asked Bao Chen to take people to search on Fenghua Road after hearing the news.

"Seven deceased people all had butterfly tattoos on their ankles, is that any point?"

The ethanol investigation still needs time to confirm, so Xu Lang asked the next question.

Xue Sheng didn't rush to speak, but bent down, and his ankle was exposed, and then Xu Lang and Ning Yanran saw that there were also two butterfly tattoos on Xue Sheng's ankles, which Xu Lang didn't notice before, and now they saw it, and they just felt a little curious, but there was still no way to explain why Xue Sheng killed the seven deceased people with tattoos on their ankles, no, it was the six deceased who had tattoos on their ankles, because the tattoos on the ankles of the last deceased Qi Lan were fake, so, After Xu Lang saw the tattoo on Xue Sheng's ankle, he looked at Xue Sheng, and the meaning was very obvious, that is, let him explain the meaning of the tattoo on his ankle.

Xue Sheng saw that Xu Lang and Ning Yanran still didn't understand, so he slowly told why he had butterfly-shaped tattoos on his ankles, and why the seven deceased killed had butterfly-shaped tattoos on their ankles.

Butterflies flying is a beautiful life scene whether in ancient or modern times, making people feel warm and full of interest in life, butterflies often remind people of love, loyal love, Xue Sheng's tattoo was tattooed together when he and Susie were in love, because of Chen Xiao, the two separated, Xue Sheng did not wash off this tattoo after he was released from prison, every time he saw this tattoo, he would think of Susie, and when he thought of Susie, he would think of Susie betraying their loyal love, so, While he had a revenge on Chen Xiao, he also developed a great hatred for Susie, and as Xue Sheng's psychology evolved step by step, becoming more and more distorted, he also began to hate the person who tattooed a butterfly on his ankle.

On the seven deceased, in addition to Qi Lan, the other six deceased have tattoos on their ankles, most of these people are tattoos because of love, such as Chen Xiao, he was in high school, he liked a girl, and went to tattoo a butterfly-shaped tattoo for that girl, but after the two graduated from college, they broke up, and finally failed to be together, and Pi Ruyu, she was the same, not only did she not stay with her first love, but also married someone else, and finally divorced, So when Xue Sheng learned that they had tattoos on their ankles, he hated these people more and more, feeling that they were all betrayed by love like Susie.

Ning Yanran knew that the butterfly-shaped tattoo had this symbolic meaning, but what she didn't expect was that the tattoo on the ankle would become one of the reasons for Xue Sheng's murder, which made people very speechless.

Xu Lang doesn't have a tattoo on his body, he has always been very reluctant to that kind of thing, so he doesn't have much research on tattoos, and he doesn't understand what the meaning of tattoos is, if he knows, when he first sees a few corpses tattooed on the ankles, he will associate this aspect.

After Xue Sheng finished talking about this, Xu Lang asked directly, "Where is Susie?" ”

Xue Sheng looked at Xu Lang, then lowered his head and stopped talking.

The interrogation ended in Xue Sheng's silence, Xu Lang and Ning Yanran stayed in the interrogation room for another half an hour, seeing that Xue Sheng didn't want to say anything more, Ning Yanran took the interrogation record to Xue Sheng and asked him to sign, Xue Sheng didn't even look at it, and directly signed his name, and then continued to be silent, Xu Lang and Ning Yanran left the No. 1 interrogation room.

When Xu Lang walked out of the interrogation room, he found that it was already more than three o'clock in the afternoon, and they had been in the interrogation room for six hours, and the interrogation record in Ning Yanran's hand was dozens of pages, a thick pile, which was really shocking.

Xu Lang first went to the toilet and put the water, and then walked out of the toilet and came to the office area of the 610 Serious Crime Team, Ning Yanran had already arrived here in advance, when Ning Yanran showed the interrogation record in her hand to others, everyone couldn't help but gasp after reading it, first shocked, and then surprised, since Xue Sheng has explained the facts of the crime and the process of the crime, then Xue Sheng is the murderer of the public toilet corpse hiding case has been determined.

Xu Lang was not as excited as the others, he first asked for a cigarette from a policeman who smoked, and after lighting it, Xu Lang sat in his seat and fell into deep thought.

Now although Xue Sheng has opened his mouth and confessed, whether it is the time of the crime, or the location of the crime, or the process of the crime, they are all very detailed, but Xu Lang They can't just rely on the suspect's confession, they also need a large number of human and material evidence, in case during the trial, Xue Sheng suddenly retracts his confession, if other evidence is not sufficient, it will be difficult for the court to rule Xue Sheng's crime, for this kind of murder, important cases, the public security system has always maintained that even if there is no confession of the suspect, they must also rely on human and physical evidence, There are other circumstantial evidence, to determine the crime of the criminal suspect, so that they can be severely punished by the law, to the deceased, to the family of the deceased, and to the common people in society, to give everyone an explanation, a satisfactory answer.

Therefore, while Xue Sheng's side was verbal-confessional, the rest of the 610 Serious Crime Team did not relax their investigation.

First of all, Bao Chen, who went to Fenghua Road, took the lead in feeding back the news, they did find the rental house on Fenghua Road, the rental house is in several old residential areas, on the first floor, they found a lot of ethanol and crime tools in the room, put these things into the evidence bag, ready to bring them back to check fingerprints, when they searched, they found that Xue Sheng made a very hidden secret door to the room, to be precise, it should be a basement, when they opened the secret door and entered the basement, they saw a very terrifying picture.

In the dim and small basement, there is only a very small light bulb inside, Bao Chen took the lead in it, turned on the switch of the light bulb, and saw that in the basement of only ten square meters, there was a naked-naked, slightly bulging belly woman, and the woman's body was covered with blood scabs, the woman seemed to be asleep, when the light bulb was on, the woman suddenly opened her eyes, sat up quickly, and then subconsciously retreated, her body kept trembling, and finally raised her head and looked at Bao Chen standing at the door, wearing uniforms.

When the woman raised her head, even Bao Chen, who had been working on the front line of the criminal police for many years, couldn't help but gasp, the woman's face was covered with dense wounds, the wounds had scabbed, and she looked particularly terrifying and scary, her original appearance was long unrecognizable, Bao Chen was stunned for a while, then walked forward and said, "We are the police, and we are here to rescue you." ”

When the woman first looked at the door, her eyes were full of fear, and when Bao Chen walked towards her, the woman subconsciously kept retreating naked-naked, and her naked-naked body was tightly attached to the cold wall, and Bao Chen had to stop and not walk forward.

When she heard Bao Chen's words and saw the police uniform Bao Chen was wearing, it took a long time for the woman to relax, her body was not trembling, tears flowed out of her eyes in an instant, her mouth opened and closed, and she made a silent sound. ”

After a while, two policewomen came down, these two policewomen have been working in the criminal investigation team for a long time, when they saw the woman, they all showed frightened expressions, but they quickly calmed down and came to the woman's side, the two of them first carefully checked the woman's body, and found that she was not too much of a problem except for being cut by a knife, and after putting on a coat for the woman, and then asked a policeman to put a coat around the woman's waist, Only then did he help the woman out of the small basement.

After the three of them left, Bao Chen took people to start an investigation in the basement, and found that in addition to a worn-out mattress in the basement, there was also a very dirty sheet, and there was some food on the side of the basement, and there was a bucket covered by a lid in the corner.

Bao Chen and the others continued to investigate at the scene, and at the same time called the 610 serious crime team to report the situation here, when they learned that there was still a naked-naked woman imprisoned in the basement, they were all shocked, everyone guessed the identity of the woman, she should not be someone else, it was Susie who had been missing for a few months, so Ning Yanran left the Public Security Bureau and rushed to the hospital.

When Ning Yanran rushed to the hospital, the woman had already been admitted to the ward, after Ning Yanran entered the ward, she found that the woman had fallen asleep deeply, when Ning Yanran saw the woman's terrifying and abnormal face, her heart was full of anger, when the woman was sleeping, she frowned, her teeth were clenched, obviously she was not sleeping soundly.

Ning Yanran found the doctor in the hospital and asked about the woman's specific situation.

After the doctor's examination, the woman has hundreds of wounds all over her body, most of them are skin trauma, the wound is not deep, in addition, there are dense tattoos everywhere on the woman's body, and the tattoos in some places are covered by each other, but these wounds and the wounds left by the tattoos have been disinfected, otherwise the woman would have died because of the wound infection, the most important point is that the woman is pregnant, and she has been pregnant for more than three months, and another point is that the woman may have been imprisoned for a long time, Physically and mentally stabbed - stimulated - greatly stimulated, temporarily lost the function of speech.

Because the woman is pregnant, they need conservative treatment when they are treated, and they cannot use some drugs that have an impact on the fetus, so now, in addition to helping the girl treat the wound, they just give the girl glucose.

When Ning Yanran rushed to the hospital, Xu Lang and the others had already contacted Susie's parents and asked them to go to the hospital to see if it was their daughter lying on the hospital bed.

When Ning Yanran told Xu Lang about the results that the doctor said, Xu Lang's face was very ugly, and Wu Yong directly slapped the table with a black face, got up from the chair, and was about to go to the No. 1 interrogation room to teach Xue Sheng a lesson, but was stopped by others, otherwise, with Wu Yong's hot temper, Xue Sheng was likely to be beaten to death by Wu Yong.

The police officers who are engaged in criminal police work will encounter all kinds of cases every day, and what kind of perverts can be encountered, but the most intolerable thing for them is those prisoners who attack the elderly, children and women, especially when they see the photos sent by Bao Chen and Ning Yanran, they are all very angry, Wu Yong, as the captain of the first criminal investigation team, has been engaged in criminal police work for five or six years, it stands to reason that he will not be so excited, the reason why he is so excited is because he has not been working in the police force for a long time, A case of abduction and trafficking of women was solved, and it was also wet in a dark and damp basement, six underage girls were imprisoned underground by gangsters, and they were inhumanely abused, at that time, after these girls were rescued, many girls suffered from depression and left sequelae, among which two girls, after being traumatized psychologically and physically, jumped from the sixth floor of the hospital not long after they came out, taking advantage of the inattention of their families and the police, Directly died, the remaining four girls, although still alive, but two of them are mentally ill, and are still hospitalized in a psychiatric hospital, the last two girls after recovery, neither returned to school, but chose to enter the society to work, although in the end the criminal gang of abducting and trafficking underage girls was finally severely punished by the law, but the psychological and physical trauma they caused to several girls is permanent, and the impact is also far-reaching.

When Susie's parents rushed to the hospital, after seeing the girl lying on the hospital bed and already unrecognizable, Susie's parents recognized the girl as their daughter at a glance, Susie's mother passed out directly, and Susie's father was also trembling with anger, red eyes, and didn't say anything for a long time, Ning Yanran saw this scene, and immediately comforted the two people on the side, in fact, her psychology was not comfortable, this is the most perverted and cruel case that Ning Yanran has encountered since she engaged in police work.

Xu Lang didn't say anything after learning the unfortunate news, just smoked hard, although he was very hungry, but he didn't have a little appetite, a colleague helped bring over the hot fast food, Xu Lang didn't even look at it, although now Xue Sheng has confessed the facts of the crime, Susie has also found it, but still to find evidence that Xue Sheng appeared at the scene of the six murders, and Lu Xing sent the screenshot from the surveillance to the technical department, the technical department was not skilled enough, and it was sent to the provincial public security department, and now there are results.

The case of hiding the body in the public toilet in S city not only caused a great sensation in S city, the relevant leaders of S city attached great importance to it, and the leaders of the provincial public security department of H also attached great importance to it, and the director of the public security department called Lu Ye many times to inquire about the progress of the case, and the mayor and secretary of S city also inquired about the matter, and after learning that Xue Sheng was arrested, the technical department of the provincial public security department also quickly came with news.

After the hard work of the comrades of the technical department of the Provincial Public Security Department, through technical means, it was finally determined that the figure that appeared in the surveillance screen at the scene of the six murders was the same person, that is, Xue Sheng.

After making a big breakthrough on the side of S City, Zhao Hua, who was working in TW City, also came with good news, that is, with the assistance of the police in TW City, they found an eyewitness who saw Xue Sheng kill Chen Xiao, and this witness was a twelve-year-old child named Xiaoma.

At that time, because it was the Chinese New Year, he was very playful, so he stole a lot of firecrackers from home, went to the wild to play with firecrackers, and accidentally saw the process of Xue Sheng killing Chen Xiao, he was still young at the time, very scared, and did not dare to tell his family about it, and it was also some time ago, during the non-stop visits of the TW City police, Xiaoma finally told his family that he saw it.

After hearing the news, the Pony's family immediately found the police who were investigating the case, accompanied by the family, the police questioned Pony in detail, and finally determined that Pony was not lying, he did see the whole process of Xue Sheng's abuse and killing of Chen Xiao at that time, and Pony often had nightmares because of this.

In the end, after the police in TW City have obtained the consent of Xiaoma's family, when Xue Sheng is in court in the future, Xiaoma will testify in court and identify Xue Sheng as the murderer.

All the members of the 610 Serious Crime Team were very happy after knowing the news, now, the human and physical evidence are available, and the missing Susie has also been found, as long as Susie recovers, as long as he gets his confession, he can enter the judicial process, but Xu Lang has a question in his heart, that is, Xue Yiming, who has not been found yet, that is, Xue Sheng's father, where is he now? What role did he play in the process of Xue Sheng's serial killing, although Xue Sheng said that the tongue soaked in formalin was Xue Yiming's, but where Xue Yiming was, Xue Sheng did not say, and Zhao Hua They had not found it yet, so Xu Lang called Zhao Hua and asked Zhao Hua to look for Xue Yiming in TW City, no matter what method was used, Xue Yiming must be found.
