"Tell me, don't you think this case is a bit unusual?"

"It's unusual, for sure, the appearance of a naked female corpse in broad daylight in an office building in the center of the city is the first time I've encountered this in all my years as a police officer. Judging from her social connections, it is very simple, and the only time she has been involved in a dispute is the recent security guard fraud incident. I would suggest looking for more clues from a forensic point of view. ”

"And what your instinct is?"

"It's supposed that we're thinking about everything. You're young and haven't experienced much, and you won't know that sometimes the truth is likely to be simple and dramatic. Although, most of the time, we are faced with a different situation. ”

Qiao Zhen didn't say anything, just shrugged, turned around and walked towards the forensic office.

Lao Qiao only shook his head behind his back: "This is a human being, can it inherit me?" ”

As soon as Forensic Doctor Chen saw Qiao Zhen, he stopped what he was doing, hesitated before speaking: "Qiao Zhen, you are here." ”

"Well, how's the check going?"

Shi Yan took off her gloves and went up to grab Qiao Zhen's shoulder: "Miss Qiao, if you come to be our leader, I will raise my hands in favor, but my work report has just been handed over to our section chief." ”

"Give me a good idea, so that you can determine the direction of the next investigation."

"Listen to this tone, are you responsible for this case to the end?"

"Senior sister, you should support me, this is the first scene my dad asked me to follow, and I have to perform well, so I don't have to be a cold bench in the future."

"Your dad strictly loves you deeply, you see that he doesn't care about us, he doesn't bother to scold."

"Who knows. Does the security guard's DNA match the semen left on the deceased's body? ”

"We've done an expedited process, and the results will be available in another half an hour. What can be ascertained is that the sexual intercourse took place the night before, not the morning before the deceased fell from a high level that day. ”

"Has the cause of death been determined?"

Shi Yan picked up a document and said with a smile: "Yes, I forgot to report this to Mr. Qiao, the fatal injury of the deceased is the skull injury caused by the fall, and the traces on the ground of the elevator warehouse can be matched." ”

Qiao Zhen made a gesture of contempt: "You guys are kidding me, you guys, now our victim is unmarried and has simple social relations, but he had sex with an unknown object the night before the accident, and the next morning he fell to his death at the bottom of the elevator cabin, and was naked." ”

"If it is certain that he killed him, then what can be the motive for the crime?" Shi Yan asked.

"What we can tell from the body is that the deceased did not show any signs of struggle or struggle when the sex took place." Dr. Chen added.

According to the family members who called the police before, the deceased never drank alcohol, let alone alcohol, and if nothing else, it happened when she was conscious. Therefore, the other party is likely to be someone she knows or even knows and has a good impression of, who will it be? The deceased was unemployed, had little contact with the outside world, and did not even have a mobile phone. ”

Everyone sat quietly around, and it seemed that they had gone far in the analysis of the case, and seemed to have returned to the original point, which is a normal situation that no one is unfamiliar with. Minutes and seconds passed.

"The problem is back here, I can't seem to find a motive for the crime, I'll go back to my job, interpreting corpses is what I do best, and I'll leave the matter of solving the case to you." Forensic Dr. Chen re-fiddled with the experimental equipment.

"It stands to reason that the deceased's social relations were simple, he usually lived in a simple house, and he had no enemies, and the most sensational dispute was the involvement of the security guard. Her family's financial situation is relatively poor, her parents are ordinary employees, and her mother has been at home on long sick leave for many years, so it is not likely to embezzle money. If you want to say that it is moving, it has achieved its goal. ”

"And there is no resistance, and it is possible that there is wishful thinking. It is unreasonable to extinguish the mouth, and the cost is too great. Qiao Zhen added.

"Who knows, sometimes it's just unpredictable." Forensic Doctor Chen sighed beside him.

Qiao Zhen and Shi Yan looked at him with emotion, and it was difficult to hide the scholarly anger in the seriousness, this topic was a little incongruous when he brought it up, and they couldn't help laughing.

"I analyzed the results, and the DNA match was 0."

"Can you just say the result?" Qiao Zhen stood up.

"I mean, it wasn't the security guard who had sex with the deceased the night before the crime."

The parents of the deceased were looking in through the forensic office in despair, and the father was desperately holding her body and shrinking down, her face was pale.

"I didn't expect this day, I didn't expect it." The mother of the deceased kept muttering to herself and burst into tears.

Qiao Zhen invited them to sit down in the inquiry room: "You two, I understand your feelings very well, and I am very sympathetic to your daughter's plight, we still need you to provide some information, I hope you can cooperate." ”

The two old men, who were over half a hundred years old, nodded with tears in their eyes.

"How long has it been since your daughter had a job, and what was her occupation before?"

"Hey, Nana is more willful, she hasn't worked in the last two years, and she depends on the income of the two of us. At first, she went to a factory recommended by the community, but then she didn't like it, and she was fired after missing us twice and absenteeism. ”

"Does she have any friends of the opposite sex who are particularly close to her in the factory and community?"

"I have the impression that she is more introverted, always a loner, and has never had any friends."

"On the night of the 12th, neither of you nor your husband and wife were at home?"

"The day before yesterday, Saturday night? Her mom and I both went to a relative's child's 10th birthday party. She was home alone. ”

"Have you noticed anything unusual about your daughter lately? Have you ever encountered something like a security guard calling the police before? ”

"My daughter usually likes to go out for a walk after dinner, she is generally more obedient, she doesn't cause trouble, she doesn't talk to strangers, we usually take care of it, and she also knows the way at home." The father of the deceased recalled carefully.

The mother of the deceased, who had not spoken, turned on her mobile phone and showed Qiao Zhen some of the photos: "You see, my daughter is very well-behaved and kind, but people who are not familiar with her will think that she behaves strangely and has a strange personality, but in fact, she has no malicious intentions. In the end, I still have to blame for not having a good baby back then. ”

"You mean, your daughter's physical condition is a little different from ordinary people?" Qiao Zhen pondered word by word.

"My daughter's brain development has been delayed because of the lack of oxygen for a long time at the beginning of birth, and her IQ is only about the level of a four- or five-year-old child, but she doesn't see this problem from her appearance at all. It stands to reason that this is a good thing, we have a fluke mentality, and we have always hoped that she can get married and have children like normal people and have her own life. I haven't told the employer and the street about this situation, and hid her as much as possible. ”

"It's us who overkill, who numb ourselves, and our self-esteem that hurts her."

Qiao Zhen suddenly remembered something: "Can I take the liberty of asking, is it possible for your daughter to take off her shirt and pants directly in a public place in the extreme heat?" ”

The husband and wife looked at each other, hesitated, and nodded silently.

"Does your daughter take the initiative to have physical contact with strangers when no one is around? Or don't refuse contact? ”
