After watching the surveillance video, Gu Song found Forensic Doctor Chen and asked her if the murderer could be a woman.

Medical examiner Chen replied: "In the 2011 case, the murderer strangled the victim directly with a rope, and the attack was extremely heavy, and he looked like a very strong person, so we speculated that the murderer was a man." In addition, women rarely use such cruel and perverted methods to commit crimes. Often, women choose a safer way to control the victim's actions before implementing the next criminal plan. Of course, if the murderer is a strong, ruthless woman, the situation you are talking about is also possible. ”

"In the case of July 7, didn't the murderer first knock the victim unconscious with a blunt object before committing the atrocity? It just so happened that we found a suspicious woman in the surveillance video according to the information provided by the witnesses, which should not be a coincidence, right? ”

"The possibility of a coincidence is very low, after all, this person is secretive and behaves strangely, and he is definitely not a ...... who went to the scene of the crime to do good deeds" Forensic Doctor Chen looked at the suspect in the picture dressed as a man, and said thoughtfully, "If this woman is the murderer of Feng Yuhua, wouldn't our previous investigation direction be completely wrong?" ”

"Sister Chen......" Gu Song suddenly frowned seriously and asked, "Do you think there is another possibility?" ”

"What is possible?"

"In that case five years ago, your analysis came to the conclusion that the murderer was more likely to be male. And in this case, we found a female suspect through eyewitness testimony and surveillance video, do you think the two cases were not committed by the same murderer? ”

"You mean to say that someone imitates the crime?" Forensic Doctor Chen asked in surprise. They had discussed this issue before, but because the modus operandi of the two cases was highly similar, and it was extremely difficult to imitate, and they had never disclosed the facts of the case, they finally made the decision to merge the cases for investigation.

"Comparing the two cases that occurred successively, although the murderer chose to commit the crime in a remote public toilet, and both used extremely cruel means to pull the victim's intestines out of the body and wrap them around the neck, there are obvious differences in the means of subduing the victim. According to our previous speculation, the murderer may have changed some of the details of the crime due to some of his own reasons. But if the two cases were not committed by the same murderer at all, some things would be more plausible to explain. ”

"Yes, you're right." Forensic Doctor Chen nodded approvingly, "Judging from the clues and autopsy results currently available, I can only say that the possibility of copying the crime is very small, but it is not equal to zero." From a professional point of view, if the murderer can imitate the case so similarly, he must have a fairly in-depth understanding and research of the case five years ago. Speaking of this, Forensic Doctor Chen's face couldn't help but show a worried look.

Gu Song knew what she was worried about, but what she had to say had to be said truthfully. "The people who have the opportunity to come into contact with the case and understand the facts of the case are nothing more than the following categories: first, the relevant personnel who participated in solving the case back then; second, the families of the victims; Third, the discoverer of the body. ”

"Aren't the discoverers of the corpses you and Chu Xinlei? Neither of you can be a murderer. ”

"yes." Gu Song shrugged his shoulders and continued, "The victim's family is far away in a remote rural area in another province, and his parents are honest farmers, so the possibility is very small. ”

"Then the rest is the first case...... "Forensic Doctor Chen couldn't accept this speculation in his heart, for her, there was nothing more frustrating than doubting the colleagues around her.

Gu Song thought about it and felt that the points he had just summarized were not very comprehensive. In fact, there is no airtight wall in this world, although the case-handling personnel must strictly abide by the regulations and keep the case under investigation confidential, but it is difficult to guarantee that no one will disclose some information to family and friends, and this situation is very difficult to investigate, almost like looking for a needle in a haystack. In addition, he thought of a possibility.

"What if the imitator is someone close to the murderer?"

At around 12 noon, Xiao Jing helped Luo Tong buy lunch back as usual.

Luo Tong had just finished helping an old woman who was suffering from a summer cold to get the medicine, stretched her waist and walked to Xiao Jing and sat down, and said distressedly: "It's so hot outside, it's hard for you to run." ”

"Brother Luo, why are you so polite to me all of a sudden?" Xiao Jing was slightly stunned, a little uncomfortable with Luo Tong's attitude towards her.

In the past few days, she felt that Luo Tong looked weird. I don't know if it's because of the hot weather, Dr. Luo, who has always been calm and calm, will show uneasiness and anxiety from time to time. Not only that, Luo Tong didn't ask her to live at home these days. Although Xiao Jing was worried about Luo Tong's health and wanted to take care of him at home, as a girl, she was embarrassed to take the initiative to ask for this.

She lifted the lid of the packing box and persuaded Luo Tong, "Brother Luo, if you are not feeling well, you can rest at home for a few days, I can handle the affairs of the clinic alone." ”

"I'm so vulnerable." Luo Tong smiled faintly, perhaps realizing that his state was a little abnormal, and he explained to Xiao Jing, "I'm really fine, but I have had a headache recently." I've been in a car accident in the past and had a serious brain injury that left me with some sequelae, as you all know. ”

"Huh?" Xiao Jing became even more worried when he heard this, "Why don't you go to the county hospital and find Dr. Pang for a brain examination, how bad it would be if the condition was seriously delayed." ”

"Don't worry, girl, I know it in my own body." Luo Tong didn't want to talk about this topic anymore, so he helped Xiao Jing open the other packing boxes, picked up a pair of chopsticks and said, "Yo, why is today's lunch so rich, there are pork ribs, and fish." ”

"Well, what I ordered at Fat Brother's restaurant are all your favorite dishes." Xiao Jing said that he sandwiched a piece of braised fish for Luo Tong, like a girl in love, with a happy expression on her face. "I see that you have been on fire these days, and you have not dared to order spicy food."

"No, that's already good." Luo Tong put the fish in his mouth and chewed it carefully, but what he felt in his mouth was a bitter taste.

The two of them ate silently for a while, and Xiao Jing said to Luo Tong casually: "Brother Luo, I don't know if it's my psychological effect, in the past few days, I always feel that someone is spying on me." ”

"What did you say?" Luo Tong put down the rice that was about to be sent to his mouth, looked at Xiao Jing in surprise and asked, "When did you start noticing?" ”

"That's ......" Xiao Jing rolled his eyes and recalled, "Since the day the police came looking for me, I felt that something was wrong around me. When I was walking on the road at night, it seemed like someone was following me, but when I looked back, there was no one. Do you think it's because there was a murder in the county, I thought too much about it? ”

"Maybe......" Luo Tong frowned, feeling a wave of unease in his heart. Xiao Jing, the murderer has not been arrested yet, it is very unsafe outside, you must be more careful. ”

"I will." Xiao Jing nodded vigorously, took out a bottle of anti-wolf spray from his pocket, and said proudly: "If the murderer dares to attack me, I will use this against him." ”
