Jian Jing asked each person the time when they saw the red cloth.
Cleaner: "I was mopping the floor outside the whole time. After mopping, I went to the toilet and never went in."
Event Manager: "I was open, and I knew you guys weren't here, so I was eating breakfast in the office. I heard someone coming outside, so I went with them. I didn't pay attention, it seemed like I had been there all along."
Planner: "I arrived very early, but the study room was almost decorated yesterday, so I didn't take a closer look. The flower baskets haven't been delivered yet, and I've been calling them all the time."
Copywriter: "I went to the reading room as soon as I arrived. At around 7:10, it seemed like the red cloth was already covering the room."
Operations: "I walked around the hall and the announcement was already there, but I was busy with media contact and didn't look closely."
Editor: "I got here at 7:30 and it's already there. I wonder who put it there at the time. It's so ugly."
Assistant to the President: "It will be there when we arrive."
Store manager: "I just looked at the door but didn't go in. I'm not sure. I just got here."
Jian Jing sorted out their testimonies. If they were not lying, the red cloth would have been covering the body at 7:10, but it was unclear whether there were books or corpses underneath.
Maybe the red cloth at the beginning was just a decoy, and someone took the opportunity to switch it. Maybe after the door was opened, someone else sneaked up and hid the body.
Kang Mucheng asked: "You are looking for someone in this way, do you think he has been bribed?"
"Yes." Jian Jing nodded. "It doesn't seem like a coincidence that the book signing event was specially held here."
Kang Mucheng looked stern and said thoughtfully, "Call them over and ask them one by one. I don't believe we won't be able to find out."
"Wait, let's take another look at the bones." Jian Jing hesitated and said softly, "I suspect it's true."
The simulated fake bone can basically be determined to be a prank. No matter who did it, it is not too late to settle the score afterwards. But if it is real, the nature is very different.
But Ji Feng had mentioned that the work of forensic doctors was busier than that of the police, so if they were asked to identify the case, they would have to wait until the afternoon.
It is better to rely on yourself than on others. It's time to draw another wave of cards.
"System, draw a common card."
[Card drawing in progress]
[Extraction completed]
[Title: Skill Card: Hard Pen Calligraphy (Elementary)]
[Description: Improve your calligraphy]
[Note: Write well to leave a good impression on others]
[Title: Skill Card: Speech (Elementary)]
[Description of content: Improve your public speaking skills and be able to speak fluently in front of a large audience]
[Note: If this skill is used well, the consequences are unpredictable]
Two consecutive skill cards cannot be considered a bad thing, especially since they are signed and thanked soon after. It can be considered a timely relief, but it is of no help in solving the case.
She gasped in pain and muttered to herself: "We need to do something practical to solve the case."
[Title: Knowledge Card·Forensic (Primary)]
[Content Description: Acquire basic knowledge of forensic medicine]
[Note: Speak for the dead and plead for the innocent]
[Title: Prop Card·Handwriting Identification (3/3)]
[Content description: Handwriting identification can be performed three times with a 100% accuracy rate]
[Note: Handwriting will betray a person’s inner thoughts]
After weighing the options, Jian Jing decided to use the Forensic Card and temporarily keep the Calligraphy and Speech Cards to see if she could get a less tight card later to synthesize an upgrade card.
Suddenly, I had more forensic knowledge in my mind.
She went back to look at the bones and the information she obtained was completely different.
The skeleton was very complete, so the first thing she noticed was the pelvis. The pelvis can determine the gender of a body. For example, the closed circle in the middle is called the upper pelvic opening. The male is like a heart, while the female is an ellipse.
However, Jian Jing had no experience, and looking left and right, she was not sure whether it was an oval or a heart. Fortunately, there was another way, which was to look at the lower opening of the pelvis. This was not a closed shape, but the pubic symphysis.
The pubic symphysis of women is a U, while that of men is a V.
After confirming the two characteristics, she determined that this was the corpse of a woman.
Similarly, the pubic bone also contains information about the age of the corpse.
Based on the nine features of the pubic symphysis surface, age can be calculated using the formula:
y=m+x1+x2+x3+x4+x5+x6+x7+x8+x9
y is the estimated age, m is a constant: male: m16.45, female: m15.32
x1 to x9 are the reference constants of nine characteristics: x1 is the symphysis groove ridge, x2 is the bone tubercle, x3 is the lower end of the symphysis, x4 is the ventral slope, x5 is the symphysis morphology, x6 is the dorsal edge, x7 is the lateral edge of the slope, x8 is the ventral edge, and x9 is the symphysis bone.
Each feature has a reference table. For example, the ventral slope, which is relatively easy to understand, has a score of 0 for absence, 3.53 for partial presence, 7.36 for complete formation, and 8.61 for loose mesh-like appearance.
Before getting started.
Jian Jing: There is a formula, just apply it directly.
After getting started.
Jian Jing: What’s the use of formulas? They’re blind!
Krypton can light up the skill tree, but it cannot give experience.
She had the knowledge points in her mind and remembered them clearly, but her eyes said she saw them and her brain said no.
An inexperienced person wouldn't know what category an image belongs to or what score to give it when he sees it.
She couldn't calculate the age, so she could only make a rough classification based on the state of the symphysis ridge - the symphysis ridge is high and sharp in adolescents, but it becomes flat in middle age, and will cause osteoporosis in old age.
This bone is neither very sharp nor very flat, and seems to be somewhere in between the two.
Looking at the auricular surface of the iliac bone, it is finely granular, with obvious horizontal structures and wavy shapes. Although her experience is somewhat difficult to break down, it is roughly estimated that she should be between 20 and 30 years old.
This is her limit.
Look for other features.
After wrapping her index finger and thumb with a tissue and turning the body over for ten minutes, Jian Jing discovered a healed crack on the right arm of the corpse, proving that the deceased had suffered a fracture once.
In this way, the basic information of the deceased appears.
A young female between 20 and 30 years old, about 163cm tall (total bone height + 5cm soft tissue thickness), had fractured her right arm once.
She invited everyone to the reading room and got straight to the point: "Just now, I have asked everyone about the corpse, and everyone said they were not sure or they did not know. Maybe you really know nothing, or maybe someone lied. Before I make a second confirmation, I must tell everyone one thing. This is not a prank. The corpse is real."
Many people showed surprised expressions on their faces.
"The deceased is a young woman, about 1.63 meters tall, with a broken right arm." Jian Jing reported the information while carefully observing everyone's expressions. "In addition, she should have been murdered. If someone thought it was a prank and moved the body here, it's not too late to admit it now. Otherwise, when the police come, you will be involved in a murder case."
This is half true and half false.
The truth is that she observed that the deceased had a concave injury on his skull, which should be a fatal injury. But she couldn't be sure whether it was murder or an accident, so she exaggerated the severity just to deceive them.
"Murder? Is that true?"
"It's okay, they've all turned into bones. They must have been dead for many years."
"Who brought this thing here, the murderer?"
Everyone was either surprised or horrified, and their reactions were all normal, except for the store manager and the event manager, who exchanged glances with a somewhat strange expression.
Jian Jing's heart moved, and she asked, "I don't know if anyone knows someone like this?"
Perhaps, the corpse appeared here not for her, but for Butian Bookstore.
Sure enough, although she didn’t give a direct answer, after the conversation, the event manager took the initiative to find her and said frankly: “I know who put the bones there, but I didn’t know it would be like this.”
Jian Jing said calmly: "Who did it?"
"Last night, I received a call from someone who said he was a fan of yours and had a surprise for you." The manager said sheepishly, "He offered 30,000 yuan and asked you to open the door earlier this morning."
She raised her eyebrows: "Do you believe it?"
"Uh, yes, they are just fans." The manager was a little uncomfortable. "This kind of thing is very common."
Jian Jing sneered in her heart, thinking that she was a fool. She bet that the manager must have thought that the other party was a member of a rival company and was here to cause trouble, but for the sake of money, he still pretended to believe it. If she hadn't claimed that she was involved in the murder case, he wouldn't have admitted it so honestly.
"What do you mean by 'it turned out to be like this'?" She held back her anger, "Do you know that guy?"
"No, no," the manager waved his hand, "I don't know the person who came here. I mean... the woman you just mentioned looks a lot like a colleague from our bookstore before."
He was not stupid. If the body had nothing to do with the bookstore, why would he admit it? Wouldn't that be asking for trouble? He could hear the description that this person looked very much like a familiar colleague. If the police found any clues, his suspicion would increase sharply.
It is better to make a small mistake than to be involved in a murder case.
The manager was very cooperative: "Her name is Lu Xue. She was originally a book manager in our bookstore. One day when she was sorting books, she was pushed by me. I fell down and broke my arm, but it was a blessing in disguise and I was promoted to the manager of the purchasing department. A year ago, she suddenly resigned and we don't know where she went."
"Does anyone have a grudge against her?" Jian Jing asked.
The manager gave an ambiguous smile: "Lü Xue is very popular. You know, there are always people who can't stand her."
Jian Jing was thoughtful. If the deceased was a former employee of Butian Bookstore, it would be very interesting to see his body here.
She had two hypotheses: the person who placed the bones was the murderer, and for some reason, he deliberately exposed the deceased; or vice versa, the person who placed the bones was not the murderer, and did so in order to lure out the real murderer.
"Did you see that?" Jian Jing asked again and again.
"No, he just asked me to open the door before seven o'clock." The manager is young, but he is already a veteran in the workplace. He knows very well that some things are better not to know.
Seeing who was coming would do him no good, but would easily lead to trouble. His previous testimony was true. After opening the door, he was browsing his phone and eating breakfast in the office, and did not go out until Jinwu's group arrived.
This presents a problem.
Is there really such a thing? If so, why didn't the surveillance camera capture the stranger
Jian Jing carefully recalled the surveillance angle and found a slight possibility: there was a blind spot in the surveillance of the first-floor gate, which could be avoided by sticking close to the wall. Then, using the cover of the bookshelf, after going up the stairs, she could directly climb over the railing to the second floor and avoid the camera facing the stairs on the second floor.
Although the requirements for skills are a bit high, it is not impossible to achieve.
In order to find out whether such a place exists, the police need to mobilize the surrounding surveillance cameras, which is difficult to do with single-minded reasoning.
She must change her strategy and find out the identity of the murderer.
