The Fire Buddha Shuichi asked, "Are you saying that Sumiko Sato may have unfavorable testimony against the murderer?" What could it be, how could a dust girl threaten the other party, could it be that this murderer was also her guest? ”

Nana Ogino nodded, "It's possible, but I think it's more important to find out Sumiko Sato's boss for questioning." After all, the only valuable information on Sumiko Zuoto is the boss and customer resources behind the scenes, maybe the murderer is the boss. ”

The Fire Buddha Xiu snorted, recorded this article, and asked, "The murderer killed Sumiko Zuoto right under your noses, but you didn't notice anything, he was already ambushed in the women's toilet?" ”

"It should be so, from our point of view, the customers who come in and out of the café can see very clearly that the murderer may not have entered and left through the main entrance."

"But according to the investigation, there is no such thing as a back door in the café, and the only place where you can still contact the outside world is the toilet, but there are iron railings on the windows of the women's toilet, and if the murderer has not mastered the skills of bone shrinking, he should not be able to get out."

Nana Ogino shook her head, "There are indeed iron railings on the windows of the women's restroom, but there are traces of damage in the men's restroom, and the outside leads to another street. Therefore, it can be inferred that the murderer sneaked into the toilet in advance, and after killing Sumiko Sato, he pulled out the iron railing that had been destroyed in advance, and he could drill out along the gap.

Then stick it back to its original place, and you can create the illusion of a murder in a closed room. If it weren't for the careful investigation of the scene, it would have been almost impossible to find traces of broken iron railings in the men's toilet. ”

Kamio Kaede found a clean white lab coat from the disinfection cabinet and put it on, and then put on a hair cover, latex gloves and a mask.

He picked up the sterilized dissecting instrument and placed it in a tray, holding it on a trolley next to the dissecting table, and nodded to Erika.

There were also two criminal policemen at the scene, and after asking Kamio Kaede and Fire Buddha Shuichi for instructions, they withdrew from the forensic office and waited outside.

Let these criminal police officers rush to the front line without forgetting their lives and fighting for their lives with murderous criminals, they may not blink their eyes, but they can't accept staying in the forensic office to see the corpses being cut off by scalpels little by little, and to see the intestines, stomach, spleen and kidneys inside.

That slow, eerie sense of fear is not something that everyone can accompose, with the exception of forensic doctors, whose profession is destined to endure such a scenario.

Therefore, forensic medicine must not only have a brave heart, but also be 'psychopathic' enough.

Erika glanced at the time, and at 15:15, pressed the timer.

On the til-inlaid dissecting table, Sumiko Sato's head rests on a rubber block, and the bumpy corpse is exposed to the examination lamp.

Erika rolled her eyelids on Sumiko Toto, the corpse's eyes were closed, and the distorted expression on her face seemed to be much more relieved than just now under the gentle touch, as if she was still asleep, only the place where the eye socket was smashed by the murderer's punch was very eye-catching, revealing a black mark.

The diffuse light of the examination lamp illuminated all parts of the corpse, and the body was moved from the café to the forensic room, and the bumps in the road made the already hideous wound even more visible, like a monster's mouth wide open.

The sharp cross scar on the chest almost cut the torso of the upper body vertically and horizontally, the shape of the knife was almost perfect, and the skin at the edge of the wound had wrinkled, clearly exposing the fatal tear at the intersection.

The wound has gradually darkened in color, taking on a grayish-black color.

Erika touched a knife on Sumiko Sato's belly, which was cut so deep that the subcutaneous fat and muscle tissue were almost turned out, looking shocking.

"There is a tear in the large intestine, and the laceration marks are flat and smooth, which should be caused by the murderer piercing a sharp weapon from the lower body, I don't know if the murderer caused it unintentionally, or if he intended to torture the victim."

Erika pointed from the knife wound on her ass to the cross-cutting wound, "The knife wound at the intersection is a fatal knife, and this knife almost pierces half of the body.

If I looked closely, I could see that there were subtle jagged marks on the edge of the wound, and I deduced that the killer had stabbed the knife into the victim's body and turned the handle of the knife, which accelerated the blood flow and accelerated the victim's death. ”

She leaned down again and took a pair of tweezers from the tray next to her with her left hand, and Kamio Kaede immediately handed over the alcohol cotton to the side.

Erika used tweezers to hold the alcohol swab and wipe off the blood stains at the intersection of Sumiko Zuoto.

The wound looked much clearer in the diffuse light of the examination lamp than it did in the dimly lit café women's bathroom.

"There were traces of friction on the edge of the wound, which should have been formed by pressing the handle of the knife against the skin, and the murderer's knife was full of strength to put people to death. At least a 20-centimeter-long sharp weapon, with some serrations, and perhaps a self-locking function. ”

After listening to this, Kamio Kaede exchanged glances with Nana Ogino on the other side, which was basically consistent with the Knight saber she analyzed.

Erika continued to check, "If I'm not mistaken, when I open Sumiko Sato's chest later, I should see the debris falling from the vertebrae......"

As she spoke, she put her hand into the wound, "Hmm...... I can feel some fragments of hard objects, which should be the broken vertebrae of the deceased. ”

She raised her head and looked at the pale-faced trio casually: "In addition to the deepest stab of this knife, it can also be observed that the position of the blade is not completely perpendicular to the intersection, and it is about 60 degrees oblique downward force.

Judging from this, the murderer was in a condescending posture at the time, holding the hilt of the knife with both hands and bayonet downward, he should have been standing at the time, while Sumiko Sato collapsed on the toilet.

Normally, when a person attacks a seated person in a standing position, his legs will be bent unconsciously, and his shoulders will collapse slightly, combined with the height of Sumiko Sato in the toilet and the 60° bevel, the murderer's height should be between 1.75 meters and 1.85 meters. ”

Fire Buddha Xiu nodded and motioned for her to continue.

Erika adjusted her thoughts, retelling the scene as if she were there, "The killer stood in front of Sumiko Sato, and placed her in the right place on the toilet, her legs curled up, and her hands clenched on the hilt of the knife and raised it high.

Then, he gathered strength, aimed at the intersection of the cross-cutting edges, and stabbed the sharp blade into the chest with force, piercing half of his body. ”

Kamio Kaede, who was laying his hands on the side, couldn't help but ask, "Is there any symbolism in this cross knife edge?" Otherwise, if the murderer wanted to kill her, he could have stabbed her in the heart directly. ”

Erika's expression was strange, "Maybe this is an artist-minded killer, or maybe it's a religious person, and he chose to carve a cross on Sato Sumiko's chest, maybe there is some symbolism......

But if this symbolism is transferred to the heart, then the cross knife is bound to be centered on the heart, but ......

As far as the structure of the human body is concerned, the heart is wrapped by ribs and cartilage, even if it is a professionally trained special forces, it is difficult to hit with one hit, and it may even take two or three knives to pierce the heart. ”

Erika raised her head and said, "Therefore, if the murderer uses the heart as the anchor point of the cross knife, it is likely that he will be stabbed several times before he can pierce the heart, in that case, the artistic symmetry of the horizontal and vertical cross knife edge will be destroyed, or in other words, the artistic sense will be lost." ”

Her expression was a little strange, "Normally, the cross generally refers to religion, the Red Cross or the Mahayana Buddhism Bodhisattva and the like, and they are all horizontal and vertical lengths, but the cross symbol on the left Fuji Sumiko seems to be about the same horizontal and vertical length, and they are not perfect 90 ° right angle horizontal and vertical symmetry......

The murderer can stab the intersection with one sword, and the control of the angle should not be so large. ”

Several people present were amazed by Erika's analysis and admired her meticulous observation of the corpse.

Kamio Kaede also stretched out his hand and gestured near the edge of the knife, and nodded, "Indeed, the cross knife edge is not completely symmetrical at right angles, the horizontal and vertical lengths are almost the same, maybe this cross symbol has other meanings." ”
