Although the two-story house is built on a small area, judging from the arrangement of the backyard, the owner of the house should love flowers and plants and life - so it also seems that the messy muddy footprints on the wooden platform are unusually abrupt.

Reminded by his grandmother, Fujiwara had already arrived in the backyard, and he naturally noticed the muddy footprints, the sliding doors were open, and the translucent white tulle curtains were blown by the cold December wind.

He heard the peculiar sound behind him that only comes when walking with a cane, and turned around and asked bluntly, "Grandma, was that how you came here?" Was the sliding door originally open or did you open it? ”

"That's what it was, the wind hasn't picked up just now, and the curtains haven't been blown up." Fujiwara Yu looked down and noticed the brown dirt at the bottom of the curtain, which should be the traces left by the muddy footprints from the past, which means that the old grandmother is not lying.

As a police officer, he would not immediately rule out the suspicion of the other party because of his age and the identity of the person who reported the eucalyptus, and after making sure that there was no problem with the witness testimony, he bent down to change into shoe covers and prepared to go to the scene of the eucalyptus.

Hearing the sound of a car parked on the side of the street, he raised his voice and shouted at Otaki Goro, who rushed here: "Officer Otaki, I'll go to the scene of the eucalyptus scene first, and this old grandmother's confession will be handed over to you!" ”

"Okay! There you go! Fujiwara nodded politely to the old woman, carefully bypassing the footprints that most likely had been left by the perpetrator, and opened the curtains and entered the living room.

There were no signs of a fight in the living room, and the only thing he cared about was the footprints on the floor and the empty milk bottle on the coffee table.

He followed the footsteps all the way to the inner room, the bedroom door was open, and before he could get closer, he smelled the strong smell of blood, and when he saw the corpse of the victim, a look of surprise appeared in his eyes.

The victim was a woman, lying face up on her back, with no clothing covering her body, but with neon ribbons decorating the Christmas tree wrapped around her body...... Twinkles of colorful neon lights.

Fujiwara Yu frowned deeply, he couldn't imagine the old grandmother's mood after witnessing such a scene, he took out the white dust-free cloth from his satchel, covered the body, and reached out to turn off the neon button.

At least let her walk decently, and the forensic class will come here to collect physical evidence. He leaned down to examine the wound on the victim's head, but fortunately, the temperature in the bedroom was relatively low and there was no strong smell of corpses, and the door of the room was open, and the smell of blood in the room had become a lot, even if he was not wearing a mask.

The amount of bleeding on the head is very large, and it is not particularly obvious from the surface, but after turning the body over, you can see that the back of the head has been beaten with dozens of heavy objects, otherwise the entire back of the head will not be sunken, and the flesh will be in a lake.

From the surface of the wound, it can be analyzed that the surface of the blunt weapon is very smooth, it should be a spherical object made of metal, and several eligible murder weapons come to mind, but there is no way to directly determine which one it is.

"Takaji, do you have any special findings?" Goro Otaki walked into the scene of the eucalyptus with his colleagues from the forensic class, and when he noticed the female victim who was draped in a white cloth, he stepped forward and asked.

In the half month that Eagle Sizong has been involved in his post, he has successfully solved six homicides, and the composure shown by this junior at the crime scene, and his calmness in the face of the murderer's quibbles, Otaki Goro has seen it.

Moreover, Eagle Division is extremely talented in the autopsy, and it is written in the entry file that he has studied in the United States for six years, and is a top student who graduated from Boston University with a major in forensic medicine.

It is important to know that it is unlikely that Japan will use autopsy methods to investigate the cause of death of the victim, and most of the cases will not be autopsied, and even if the department is present, it will only make a preliminary autopsy report, so for the police, the presence of a companion with professional knowledge can save a lot of troublesome steps.

"The cause of death can be determined to be a primary brain injury caused by dozens of blunt blows to the head, with extremely heavy bleeding. Judging from the morphology of the zombies and corpse spots, the time of death should be between 23 o'clock yesterday and 1 o'clock in the morning today. ”

"Dozens of times? It seems that the murderer hated the victim very much. Otaki Goro couldn't help frowning, thinking of the old man outside, you must know that the elders who are parents don't look down on white-haired people to send black-haired people.

The victim's mother must have been so broken and sad in her heart. Fujiwara nodded in agreement with Officer Otaki's thoughts, and he held a pen in his hand and gestured, "The wounds on the victim's body are concentrated on the back of the right side of the head, and there are pinch marks on the back of her neck. This shows that the murderer used his left hand to clamp the victim's back erection neck and pressed it the bed, and then held the murder weapon with his right hand and repeatedly hammered the victim's head. Otaki-senpai, why do you think the murderer deliberately placed her in a supine position? Otaki Goro didn't answer in a hurry, he reached out and lifted the white cloth and couldn't help but be stunned when he saw the state of the victim's body, and quickly covered the white cloth with an ugly face, and he also understood why Takaji covered the body with a white cloth.

He looked at the victim's pale and bloodless face and said his analysis: "The reason why the murderer did this is because he wanted to humiliate the victim, whether it was the act of stripping off his clothes or the act of wrapping neon ribbons around his body, he wanted to tell everyone that she had been violated and toyed with. ”

"The murderer did not invade the victim, he did it so that the victim would not get dignity after death, just to humiliate her." Fujiwara Yu put the pen back in his pocket and gestured: "He wanted to mislead the police that the murderer was a random sex offender, but unfortunately he did a bit too much, but it exposed the problem." ”

"What's the problem?"

"The murderer not only knew the victim but was also very familiar, and there was no trace of the sliding door lock, which is enough to prove that the murderer and the victim knew each other, and the victim personally invited him into the room. It was early in the morning, and even if you lived with your family, it was impossible to let strangers into the house.

And the victim loves cleanliness very much, how can it be possible for people to wear a pair of muddy shoes into the house?

"Wait, you just said single mother?"

"Hmm." Fujiwara Yu reached out and picked up a group photo placed on the dresser, in which the victim was smiling brightly and holding a little boy in a karate uniform, and it was not difficult to distinguish that they were mother and son.

However, there was no little boy at the scene, and the grandmother of the informant, who was the mother of the victim, did not mention the matter of her grandson, which means that the child was awarded to the biological father after the victim's divorce, which is not difficult to reason.

"I think we can start with the social connections of the victims, let's find out the situation first."

"Well, I'll have to ask the old woman, she should know a lot of things."
