Jian Jing asked each person the time they saw the red cloth.
Cleaner: "I was mopping the floor outside. I went to the bathroom after mopping and never went in."
Event manager: "I opened the door. I knew you guys weren't here, so I was eating breakfast in the office. I heard someone coming outside and went with them. I didn't pay attention. It seems like I've been there all the time."
Planner: "I arrived very early, but the study hall was almost decorated yesterday. I didn't look closely. The flower baskets haven't been delivered yet. I've been on the phone with them."
Copywriter: "I went to the study hall as soon as I arrived. It was around 7:10. It seemed like the red cloth was in the study hall. The cloth was already there."
Operations: "I walked around the hall and the cloth was there, but I was busy with the media and didn't look carefully."
Editor-in-Chief: "I got here at 7:30 and it was there. I was wondering who put it there at the time. It was so ugly."
Assistant to the President: "It was there when we arrived."
Store Manager: "I looked at the door, but didn't go in. I'm not sure. I just came."
Jian Jing sorted out their testimonies. If no one lied, the red cloth was already there at 7:10, but it was impossible to determine whether there was a book or a corpse underneath.
Maybe the red cloth was just a trick at the beginning, and someone took the opportunity to switch it later, or maybe someone else sneaked up after the door was opened and hid the corpse.
Kang Mucheng asked, "Your method of finding out, do you think someone was bought?"
"Yes." Jian Jing nodded, "It's not a coincidence that they put it up specifically for my autograph session."
Kang Mucheng looked stern, and pondered, "I'll call everyone over and ask them one by one. I don't believe I can't get the answer."
"Wait, I want to take another look at the bones." Jian Jing hesitated, and said softly, "I suspect it's real."
Simulated fake human bones can basically be determined to be a prank. No matter who did it, it won't be too late to settle the score afterwards, but if it's real, the nature is very different.
But Ji Feng mentioned to her that the work of forensic doctors is busier than that of the police. If they want to ask them to identify it, they have to wait until the afternoon. It
's better to rely on yourself than on others. It's time to draw another wave of cards.
"System, draw a normal card."
[Drawing cards]
[Drawing completed]
[Name: Skill Card·Hard Pen Calligraphy (Beginner)]
[Description: Improve your calligraphy]
[Note: Write well and leave a good impression]
[Name: Skill Card·Speech (Beginner)]
[Description: Improve your speaking ability and be able to talk fluently in front of many onlookers]
[Note: If you use this skill well, the consequences are unpredictable]
Two consecutive skill cards are not bad, especially since you will have to sign and give a thank you speech soon. It can be regarded as timely rain, but it does not help solve the case at all.
She gasped in pain and muttered to herself: I want to solve the case, do something practical.
[Name: Knowledge Card·Forensic (Elementary)]
[Description: Gain basic knowledge of forensic medicine]
[Note: Speak for the dead and speak for the innocent]
[Name: Item Card·Handwriting Identification (3/3)]
[Description: Handwriting identification can be performed three times with a 100% accuracy rate]
[Note: Handwriting will betray a person's heart]
After careful consideration, Jian Jing decided to use the Forensic Medicine Card, temporarily retaining the calligraphy and speech cards, and see if she can find a less important card in the future to synthesize an upgrade card.
Suddenly, she had more knowledge of forensic medicine in her mind.
She went back to look at the corpse, and the information she got was earth-shaking.
The corpse was very complete, so the first thing she noticed was the pelvis. The pelvis can determine a person's gender. For example, the closed circle in the middle is called the upper pelvic opening. It looks like a heart for men and an ellipse for women.
However, Jian Jing had no experience, and she looked left and right, and was not sure whether it was an ellipse or a heart. Fortunately, there is another way, which is to look at the lower pelvic opening. This is not a closed shape, but the pubic symphysis.
The pubic symphysis of women is a U, and that of men is a V.
After the two features were matched and confirmed, she determined that this was a female corpse.
Similarly, the pubic bone also contains information about the age of the corpse.
Age can be calculated based on the nine features of the symphysis pubis. The formula is:
Y=M X1 X2 X3 X4 X5 X6 X7 X8 X9.
Y is the estimated age, M is a constant: M16.45 for males and M15.32 for females.
X1 to X9 are the reference constants of the nine features: X1 is the symphysis groove ridge, X2 is the ossified 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 easier to understand, is absent for 0 points, partially present for 3.53, fully formed for 7.36, and mesh-like loose for 8.61.
Before getting started.
Jian Jing: I have the formula, just apply it.
After getting started.
Jian Jing: What's the use of the formula, my eyes are so bad!
Krypton can light up the skill tree, but it can't give experience.
She has knowledge points in her mind and remembers them clearly, but her eyes say she sees them, but her brain says no.
People without experience don't know which category they belong to or what score to give them when they see them.
She can't calculate the age, so she can only make a rough division based on the state of the syndesmotic ridge - the syndesmotic ridge of adolescents is high and sharp, but it will become flat in middle age, and when they are old, they will have osteoporosis.
This bone is not particularly sharp, nor is it very flat, it seems to be in between the two.
Look at the auricular surface of the iliac bone (qia), which is granular, with obvious horizontal structures and wavy. Although her experience is a bit hard to tell, I roughly estimate her to be between 20 and 30 years old.
This is her limit.
Let's look for other characteristics.
She wrapped her index finger and thumb with a tissue and turned the body carefully for ten minutes. Then she found a healed crack on the right arm of the corpse, proving that the deceased had suffered a fracture.
In this way, the basic information of the deceased appeared.
A young woman between 20 and 30 years old, about 163cm tall (full body bone height 5cm soft tissue thickness), with a fracture in her right arm.
She invited everyone to the study room and got straight to the point: "Just now, I have asked everyone about the corpse. Everyone either said they were not sure or they didn't know. Maybe you really know nothing, or 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.
"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, "And, she should have died of homicide. If anyone 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 homicide case."
This was half true and half false.
The true part was that she observed that the deceased had a depressed skull injury, which should be a fatal injury. But she couldn't be sure whether it was homicide or an accident, and deliberately exaggerated the severity just to deceive them.
"Murder? Is it true?"
"It has nothing to do with us. It has all turned into bones. He must have been dead for many years."
"Who moved this thing here, the murderer?"
Everyone was either surprised or terrified, and their reactions were normal. Only the store manager and the event manager exchanged glances with a strange expression.
Jian Jing's heart moved, and she asked: "I want to know, does anyone know such a person?"
Maybe the corpse appeared here not for her, but for Butian Bookstore.
Sure enough, although no one answered directly, when the conversation ended, the event manager took the initiative to find her and confessed, "I know who put the bones there, but I didn't know it would be like this."
Jian Jing calmed down and said, "Who did it?"
"Last night, I received a call saying it was your fan who wanted to give you a surprise." The manager said embarrassedly, "He offered 30,000 yuan and asked me to open the door earlier this morning."
She raised her eyebrows: "Did you believe it?"
"Uh, yes, I thought it was a fan." The manager was a little uncomfortable, "This kind of thing is very common."
Jian Jing sneered in her heart, thinking that she was being treated as a fool. She dared to bet that the manager must have thought that the other party was someone from a rival company and was intentionally causing trouble, but for the sake of money, he still pretended to believe it. If she hadn't claimed to be involved in a 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 person?"
"No, no," the manager waved his hands, "I don't know the person who came. I mean... the woman you just mentioned looks a lot like a colleague of ours in the bookstore."
He was not stupid. If the body had nothing to do with the bookstore, why would he admit it? Isn't that asking for trouble? It sounds like this person looks like a familiar colleague. If the police find any clues, his suspicion will rise sharply.
It's 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 the book manager of our bookstore. One day when she was sorting books, someone pushed the ladder and she fell down and broke her arm. But she turned out to be a blessing in disguise and was promoted to the manager of the purchasing department. A year ago, she suddenly resigned and we didn't know where she went."
"Does anyone have a grudge against her?" Jian Jing asked.
The manager showed an ambiguous smile: "Lu Xue is very popular. You know, there are always people who can't stand it."
Jian Jing was thoughtful. If the deceased was a former employee of Butian Bookstore, it would be very interesting to find the bones here.
She had two hypotheses: the person who placed the corpse was the murderer, and he deliberately exposed the deceased for some reason, or vice versa, the person who placed the corpse was not the murderer, and did so in order to catch the real murderer.
"Did you see that person?" Jian Jing repeatedly confirmed.
"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 is coming will not benefit him, but will easily get him into trouble. His previous testimony was true. After opening the door, he was in the office, browsing his phone and eating breakfast, and did not go out until Jinwu's people came.
This poses a problem.
Is there really such a person? If so, why didn't the surveillance capture the stranger?
Jian Jing carefully recalled the surveillance angles and found a small possibility: the surveillance camera at the first floor gate had a blind spot, and she could avoid it by sticking close to the wall, and then use the bookshelf as a cover, go up the stairs, and directly climb over the railing to the second floor to avoid the camera on the second floor facing the stairs.
Although it requires a bit more skill, it is not impossible.
To find out whether there is such a person, the police need to mobilize the surrounding surveillance cameras, which is difficult to do with the reasoning of one person.
She must change her strategy and find out the identity of the murderer.
