After the "7.7 Murder Case", the police quickly sorted out the social relationship of the victim Feng Yuhua and ruled out the possibility of acquaintances committing the crime.

Feng Yuhua is a simple and kind little girl who has not been deeply involved in the world, living a simple life from home to barbecue restaurant, and only a handful of people she comes into contact with on weekdays. She hasn't found a boyfriend yet, and the only man who can be considered a little ambiguous is Tang Ming, the owner of the barbecue restaurant. However, Tang Ming did not have the time and motivation to commit the crime, and even did not have the corresponding ability to commit the crime, so he was not on the list of criminal suspects.

Through the summary and verification of vicious criminal cases in R city and its surrounding areas, the police have not found any cases with similar characteristics in recent years. The murderer did not have the habit of hiding the body after committing the crime, so it can be basically determined that the murderer has only committed two crimes so far, and the time and place of the crime are as follows:

On June 18, 2011, a public toilet in a shantytown in the northern suburbs of R City;

On July 7, 2016, in Jinshui County, R City (60 kilometers away from R City), a public toilet in an alley across the street from a snack street.

In order to ensure that the analysis is in place, the police also focused on cases involving attacks on women in recent years (especially those that occurred near public toilets), and investigated the suspects who were recorded one by one. (Mainly considering that the murderer may have failed in his crime.) ）

In response to the two cases that have been identified, the police conducted an in-depth investigation into the relationship between the two victims, confirming that they did not have a common social connection and that the killer chose them as a target should have been random.

According to the clues provided by the "voyeur" Huzi, the task force further determined the basic characteristics of the suspect: the suspect is male, between 30 and 40 years old, about 171cm tall, weighs about 60 kg, may have a medical background, and has a certain understanding of human body structure and anatomy.

This person may have experienced major changes in his life or work, resulting in psychological abnormalities, and he or she may take revenge on society by killing people in an extremely bad way.

Combined with the analysis of the murderer's crime location, the murderer is likely to be from R City or the surrounding area, and it cannot be ruled out that the murderer may be living in Jinshui County.

Considering that the murderer disappeared for five years and came back to commit the crime, and the modus operandi has changed somewhat, it is speculated that the murderer may have been sick and hospitalized during the past five years, or had an accident, which caused his physical condition to change. And the reason that prompted him to come out again to commit crimes may be that his life has taken another turn......

The special case group referred to the results of some psychological analyses and first searched for criminal suspects who matched the characteristics in Jinshui County. Unexpectedly, on the third day after the incident, a clinic doctor named Luo Tong entered their line of sight.

Because they did not have any substantive evidence of the crime, the police only called Luo Tong to the county public security bureau for questioning in the name of "assisting in the investigation".

Luo Tong, a native of Jinshui County, is 37 years old and currently runs a small clinic in Jinshui County.

In 1998, Luo Tong was admitted to R University of Traditional Chinese Medicine with excellent results and began his dream of studying. Because of his bright mind and hard work, his grades in college have always been among the best, leaving a very good impression on his tutors and school leaders.

After graduation, under the recommendation of his mentor, Luo Tong successfully became a surgeon in the Affiliated Hospital of R City University of Traditional Chinese Medicine, and his life and work were all smooth and enviable.

In 2008, he got married and had children in R City, and everything is going in the best direction.

However, the sky is unpredictable.

During the Spring Festival of 2011, Luo Tong drove his wife and children back to his hometown in Jinshui County from R City for the New Year, and encountered a tragic car accident on the way. Their sedan was crushed by a large truck that overturned, and Luo Tong's wife and children were killed instantly. Fortunately, the driver's seat in front of him was not the main pressure area, and Luo Tong picked up a life from the hands of death, but he also woke up after being in a coma in the hospital for more than half a month.

Four months later, Luo Tong's injuries were basically healed, but his spirit was very strongly stimulated. He quit his job at the hospital, underwent a period of psychotherapy, and finally returned to his hometown in Jinshui County, where he planned to spend the rest of his life.

In the past few years since he returned to Jinshui County, Luo Tong has been hospitalized once for a recurrence of an old injury, and his physical condition is much worse than before.

Based on a number of factors, the police believe that Luo Tong is more in line with the characteristics of the suspect. What's more, Luo Tong used to be a doctor of general surgery, with excellent medical skills and full ability to commit crimes.

The only suspicion is that Luo Tong's height is 176cm and his weight is about 145 pounds, which is a certain deviation from the suspect witnessed by Huzi at the scene of the crime. Of course, this may be caused by Huzi's inaccurate visual inspection ability, or it may be that Huzi only saw a passer-by A at the scene of the crime, which has nothing to do with this case.

In the interrogation room, Qiao Sheng and Gu Song sat opposite Luo Tong. Qiao Sheng was in charge of questioning, while Gu Song was on the side to make notes for them.

Luo Tong is a man with a gentle appearance and a calm and calm appearance. I don't know if it's because he's been tortured too much in recent years, and his expression is a little numb. In the face of the two serious-looking policemen, he behaved very calmly, neither surprised nor the slightest dissatisfaction or impatience, and just sat quietly and waited, as if in his own clinic, calmly.

There are usually only two possibilities for a suspect to show such an attitude: one is that the case to be investigated by the police really has nothing to do with him, he has no ghost in his heart, and he is sitting upright; The other is that his psychological quality is too good, too good at concealment, and he doesn't pay attention to the police at all.

Which kind of Luo Tong belongs to is still unknown.

Without any evidence, he was just one of the suspects, Qiao Sheng didn't want to make the atmosphere too serious, and asked like a friend chatting: "Doctor Luo, you must have heard about the case that happened on the night of July 7, right?" ”

"Yes, I heard that." Luo Tong replied lightly.

"What do you think of that case?"

"Me?" Luo Tong didn't quite understand what Qiao Sheng meant, "What are you referring to?" ”

"It is to analyze from a professional point of view, the murderer's unique modus operandi."

"I'm sorry." Luo Tong smiled apologetically and said, "I don't know the specific circumstances of the case, and there is not much information leaked in the news." ”

Hearing Luo Tong's answer, Gu Song couldn't help but glance up at him. Obviously, Qiao Sheng asked this question to take this opportunity to deceive the other party, in case he accidentally said one, two, three, it would be tantamount to exposing his knowledge of the inside story of the case.

Qiao Sheng didn't react on the surface, but in his heart he knew that a highly educated criminal suspect like Luo Tong was not easy to deal with. He took out a few photos from the folder, put them on the table in front of Luo Tong and said, "Take a look first, this is the murderer's cruel and perverted modus operandi." ”

Luo Tong used to be a surgeon and had long been accustomed to all kinds of bloody scenes, but when he saw the photos that Qiao Sheng handed him, he still frowned slightly, and said in disbelief: "I didn't expect this case to be so terrible, the murderer turned out to be ......" He paused for a moment and asked in confusion, "How did the murderer do it?" ”

"Directly pulled the intestines out of the victim's lower body with his hands."

"This ......" Luo Tong suddenly didn't know what to say. He picked up one of the clearer photos, looked at it carefully for a few seconds, and said thoughtfully, "The murderer's methods are very professional, not like a layman's doing." ”

"You think so, too?"

"Yes, even if the murderer has no professional training, he must have taught himself some relevant knowledge."

"If you were asked to complete this series of movements, how long would it take?" Qiao Sheng inquired with interest.

Luo Tong was stunned, and looked at Qiao Sheng inexplicably, "Officer Qiao, what do you mean by asking?" ”

"It's not interesting, I just want to hear what the professionals have to say."

Luo Tong was a little unhappy, but he didn't act like most suspects when he heard a question that was unfavorable to him. Suppressing the resentment in his heart, he replied in a clear and coherent manner, "First of all, I have never thought of such a terrible problem, and I have no way of estimating how long it will take to do such a thing. Secondly, I haven't been on the operating table for many years, and my professional knowledge has long been rusty. I'm just showing a patient a headache and brain fever in the clinic right now, and I'm afraid I can't do this kind of thing. Finally, if you suspect that I am a murderer, please show me the evidence. ”

"Doctor Luo, we didn't say you were a murderer." Gu Song couldn't help but interject, and said in his heart that this man was really in chaos. It's okay if the case has nothing to do with him, but if it does, it's not easy to handle.

Since the other party took the initiative to ask this question, Qiao Sheng took the opportunity to ask: "Doctor Luo, between 9:30 and 10:30 on July 7, where are you and what are you doing?" ”

"I'm in my own home."

"Can anyone prove it?"

"Yes." Luo Tong turned his gaze to the side and replied with some reluctance, "That night, Xiao Jing in the clinic was at my house. ”

"What is she doing at your house?"

"This ...... Is it necessary for me to answer this question? ”

"In order to prove your innocence, you better answer truthfully." Gu Song kindly reminded, "After you think about it, we'll verify your alibi later." ”

Of course Luo Tong understood this, he laughed self-deprecatingly and said, "Actually, it's nothing, I have a lover relationship with Xiaojing." Although we haven't made our relationship public, we've been dating privately for more than two months. ”

Because he had investigated Luo Tong's personal information in advance, Gu Song had some understanding of the situation in his clinic. Xiao Jing mentioned by Luo Tong just now is an assistant in the clinic, she looks pure and cute, she is only 22 years old this year, 15 years younger than Luo Tong, no wonder he said that the relationship between the two would not be so comfortable.

"When did Xiao Jing come to work at your clinic?"

"Last summer, she graduated from nursing school and came to my clinic through an acquaintance's introduction."

"Doctor Luo......" Qiao Sheng pondered for a moment, and suddenly changed his words, "Do you think the murderer's modus operandi this time is any different from the one five years ago?" This is another trap, Qiao Sheng is still testing Luo Tong's reaction.

A look of surprise flashed on Luo Tong's face, and he asked suspiciously, "Five years ago, did a similar case happen in Jinshui County?" ”

"No, not here, it's in R City. I remember when that case happened, you seemed to be living in R City, and you returned to Jinshui County a few years later. ”

"I'm sorry, Officer Joe, but I'm a little out of your pace." Luo Tong finally showed a hint of gloom. "You're talking about the July 7 murder just now, why are you mentioning the case from five years ago? Could it be that the same murderer was responsible for these two cases? If you suspect that I am suspected of committing a crime, I can't give you an alibi from five years ago. ”

"Don't worry, I'm not going to ask about things that can't be confirmed. I now ask you one last question, why do you think the killer would have resorted to such a brutal method of killing? ”

Luo Tong frowned, thought about it seriously and said, "This kind of thing can only be done by perverts, and I can't think of any other reason for this." ”

Is it possible that it is to vent the dissatisfaction and anger in the heart? For example, complaining about God's unfair treatment of him? ”

"Maybe." Luo Tong shrugged his shoulders slightly, "I'm not a murderer, how can I understand his thoughts......

"Okay, thank you for your cooperation. That's all for today. ”
