"Huh?" Xiao Fang let out a soft sigh and lifted the palm of the skeletal hand up.

Ye Fan's gaze was fixed on this skull hand before Xiao Fang, judging from the shape, this should be a left hand, but it was not a complete hand bone.

"What's wrong?" He Pingfei was turning his eyes to look at the layout of this library, observing everyone's expressions, and suddenly heard Xiao Fang's startled voice in his ears, and immediately turned around and asked.

"The skeletal hand has missing the first barfinger on its left tail finger. Xiao Fang raised the skeletal hand in front of He Pingfei's eyes to show him.

He Pingfei took a look, and sure enough, the tail finger of this skeleton hand only had two sections, and the top one was missing.

"Brother Hei, search the scene carefully and pay attention to see if there is any missing phalanx. He Pingfei shouted to the technical police officer who was collecting evidence between the bookshelves.

"Understood. The technical police officer is the black brother nodded in response, bowing his head and looking more carefully between the gaps in the bookshelves.

Ye Fan's gaze also swept over the ground between the two bookshelves, and he didn't find it, it was not ruled out that it was pressed under the books scattered on the ground or in some gap, after all, such a small finger bone, it was not easy to find it in such a large and somewhat messy space.

According to Yun Xueshuang's description, Lin Yanyan should have been looking for books in front of the eleventh bookshelf at that time, but somehow a pair of skeletal hands suddenly appeared and grabbed her neck, she was frightened, screamed, waved the books on the bookshelf with both hands, swept the books to the ground, and retreated in fright, hit the bookshelf behind her, and even knocked down the bookshelf because of the great force.

Hearing her screams, the students in this library, including Yun Xueshuang and the others, heard the sound, and then saw the scene of Lin Yanyan holding a pair of skeletal hands around her neck.

If the tail phalanx of the left skull hand was broken when she pinched Lin Yanyan, or when she was struggling, it would never be able to escape this range.

Unless...... The left skull's tail phalanx was missing before it appeared.

Ye Fan floated beside Brother Hei, watching him pick up the books that fell on the ground one by one and put them into a special plastic bag, these are all physical evidence.

Whether the skeletons are real or fake, whether it is a homicide or a hoax, it will appear in the library because someone must have brought them in, so in the process, everything that may have been touched, where it passed, will leave traces.

The books that fell on the ground were all picked up, and there were no other foreign objects on the clean and smooth ground, and there was only a small gap at the bottom of the bookshelf, and it was impossible for the finger bones to fall into it.

didn't find the finger bones, Ye Fan set his eyes on the bookshelf, the bookshelf has six layers, the books that were swept down by Lin Yanyan are on the fourth floor, and one is missing on the fifth floor, it seems that Lin Yanyan should have taken it down by herself.

The school bookshelves are wooden double-sided bookshelves, with lattices between each room, and the books in the second compartment of the fourth floor are swept down to reveal the books on the opposite side.

Ye Fan stretched his head over, but he didn't notice anything unusual, so he took a closer look and then retreated.

Brother Hei also paid attention to the bookshelves and took fingerprints on them, but this is the school library, and the students who come and go every day, as well as the librarian, basically can't put anything useful.

Ye Fan looked at Brother Hei's professional movements, and there was nothing valuable to see here for the time being, so his figure floated and walked towards Lin Yanyan's location, where a criminal investigation police officer was recording a confession for her, and He Pingfei was watching from the side.

On the left side of the library are rows of bookshelves, and on the right side of the window, there are rectangular desks for students to read and study.

Lin Yanyan and the three male teachers sat on the chair of the innermost desk, and the three male teachers were also present at the time.

The police officer who recorded the confession sat opposite, asking for the confession while recording it in the notebook, He Pingfei stood next to him, and did not make a sound, but his eyes swept over her from time to time when Lin Yanyan answered.

Lin Yanyan was overly frightened, holding a water cup in her hand, she drank half of the water in the cup, and the whole person looked much calmer than just now.

Ye Fan stood behind the criminal investigation police officer who recorded the confession, how he carefully observed Lin Yanyan like a flat fly, sometimes the victim's confession and physical performance told them more than the scene environment.

Looking at it this way, Ye Fan did find something sharp-eyed.

There were several red marks on Lin Yanyan's neck, Ye Fan took a closer look, there were four on the left and three on the right, the color was a little dark, as if it had been scratched by a fingernail, and the deepest place under the throat was broken and oozed blood, and that position should be the position of the thumb.

It seems that the skeleton's hand is quite hard, and if the force is greater, it can be directly inserted into the throat.

As a delicate woman, she was suddenly choked by a pair of skeletal hands, and she was scared half to death, and she was not stunned on the spot, she was bold.

Lin Yanyan's panic and pity are normal, but when she answered the question, did she say it too clearly?

People who have just been frightened will have a certain degree of confusion in their thinking in a short period of time, and subconsciously will refuse to recall the scene at that time, hesitate and pause when answering interrogations, and will show resistance, and will cause fear to re-induce and manifest it.

But Lin Yanyan didn't, or pretended to have, when it came to the appearance of the skeleton hand without warning, she did pause, and her body shook a little, others thought she remembered the scene and became scared, Xie Qi also patted her shoulder comfortingly.

However, Ye Fan noticed that at the moment of pause, Lin Yanyan's eyes swept over the cold anger, and the shaking of her body was not afraid, but suppressed anger.

Ye Fan also felt the weak vitality around her fluctuate, and at this time she also remembered that Lin Yanyan was a cultivator, no matter how delicate a cultivator was, she was not an ordinary woman.

The moment the skeleton hand suddenly appeared, she didn't react, and it was normal to be scared subconsciously, but the fear and fear after that were more ingredient, maybe pretending.

In order to hide her identity and not let people notice that something is wrong with her, or is it to make people feel sorry?

Ye Fan's eyes flashed over the three male teachers sitting beside her, and then moved to the distance of the two desks, standing by the window and talking to the school leader.

In addition to the vice president, there are also the director of the medical school, the director of the medical school, and two leaders that Ye Fan does not know.

The director of the School of Forensic Medicine is surnamed Mu, who is Mu Yuan's father, although he seems to be discussing problems with the vice principal with a serious face, but his afterglow has been falling on Lin Yanyan, and he is very concerned.

Ye Fan sneered lightly, retracted his gaze, and heard the police officer who recorded the confession ask: "Assistant Teacher Lin Yanyan, have you had any conflicts with people recently?" or ......is it a bad relationship?"
