Instead of going directly to the home of the second victim, Miyo Takayama, he went to a convenience store on a nearby street and bought a map of the Osaka area. Now that there were two victims, he could use the map to infer the murderer's location.

First, use a straight line to connect the homes of the two victims, then extend both ends of the straight line to twice the length and use it as the diameter of the circle. The circle drawn is most likely the murderer's living area.

"There are two pet hospitals related to pets in this area. If we find signs of pets in Takayama Midori's home, we can basically conclude the murderer's occupation." Fujiwara Yu looked at the two-story independent house in front of him. It can be seen that Takayama Midori is also a single woman with an independent house. This is the same living condition as the previous victim. I'm afraid the house is also a mess.

Hattori Heiji silently took out his mask and put it back on. After climbing over the wall and entering the crime scene for the second time, his ability to accept things had greatly improved. He no longer felt nauseous like before. He now only wanted to find the murderer as quickly as possible and stop his crime.

But after arriving at the door of the living room, both of them couldn't help but frown, and at the same time they had a bad premonition in their hearts.

Because just by standing outside the door, you can smell the strong stench of corpse coming through the crack, which is inconsistent with the information provided by Otaki Goro. Could it be that Takayama Midori is the first victim?

After the two men pushed the door open with a hint of doubt, the stench of decay and the flies flying in the living room announced that this was the crime scene. But after seeing the pool of blood and flesh covered in rotten flesh, Hattori Heiji showed an expression of disbelief on his face. He never expected to see such a scene.

That's not a severed limb, it's a baby that has been dead for who knows how many days. Judging from its size, it must not have been born in a normal time period.

Hattori Heiji gritted his teeth and punched the door frame. He didn't expect that the murderer was so cruel as to kill a premature baby. The words he wanted to curse were stuck in his throat and he didn't know what words to use to describe the murderer.

Fujiwara Yu quickly calmed himself down after being shocked. He walked towards the bloody body of the baby with a serious expression. Even though he couldn't accept it, he had to conduct a careful preliminary autopsy on it.

Babies decay faster than adults. Judging from his height alone, he is a premature baby and more likely to have been "born" through a miscarriage.

After realizing this problem, Fujiwara Yu imagined in his mind everything the murderer had done to the victim: when he was kidnapping, the murderer discovered that Takayama Midori was a single mother who was pregnant before marriage, and then used some method to induce her to have a natural miscarriage and "give birth" to a dead baby.

There are many possibilities for natural miscarriage, and the most likely cause used by the murderer is alcoholism.

Fujiwara Yu got up and walked to the trash can in the open kitchen. After seeing several empty vodka bottles in it, he confirmed that his guess was correct. The murderer did use alcoholism to cause Takayama Midori to have a miscarriage.

But just as he opened the refrigerator door, he realized that his judgment was wrong. The mistake was that the person who was pregnant before marriage was not Takayama Midori who had lost her torso.

After Fujiwara Yu gently closed the refrigerator door, he turned around to check if there was any pet hair on the sofa and gave instructions:

"Hattori, call Otaki-senpai and tell him... there is a third victim."

The head of the third victim was in the refrigerator. She was more likely the mother of the dead baby. The reason why the scene was so smelly was not only because the dead baby's body was not handled properly, but also because dismemberment had occurred here twice, with an interval of at least one week.

Hattori Heiji's eyes fell on the refrigerator that had just been closed. He bit his lower lip, took out his mobile phone, called Otaki Goro and told him the truth. After completing the task, he could no longer control his emotions. He secretly walked outside the house, took off his mask, took several deep breaths, and finally managed to keep the tears from welling up in his eyes.

He sniffed hard twice, put on his mask again, and returned to the bloody crime scene. He looked at Takashi Sosuke, who had already put the found evidence into a bag, and asked:

"Brother Yingsi, is there anything I can help you with?"

His strong nasal tone quickly betrayed him, but Fujiwara Yu pretended not to know, because in his eyes, Hattori Heiji was very outstanding, and it was good enough to be able to do this at his age. Many adults could not be so steady.

Moreover, he has always believed that police and detectives must have empathy while having law enforcement and adaptability. People who lack empathy often bring prejudice and indifference into their work, which is not helpful for cases and sometimes even has irreversible impact on cases.

"Of course I have. I've already found pet hair. Now we need to confirm the identity of the third victim. I'm assuming that either she's living with Takayama Midori, or she's not living in a separate residence. Do you dare to confirm her identity?"

Even if Hattori Heiji didn't dare to open the refrigerator, Fujiwara Yu would not think that he was not capable of becoming a detective. After all, he was only fifteen years old this year. People who would achieve great things in the future would not dare to exaggerate and say that they were just as good at the age of fifteen.

"dare."

Hattori Heiji always does what he says. In order to become a qualified detective, he is willing to challenge himself. He took a deep breath and prepared himself mentally before slowly opening the refrigerator door.

He carefully observed the head wrapped in the vacuum bag, memorized the face, and called Otaki Goro again. This time, he didn't need Brother Takashi's reminder. He directly asked Otaki to help send him a list of missing female persons who had disappeared recently. He needed to compare it with the appearance of the unknown victim.

Within twenty minutes, Usuke Sakata came out of the house with the missing person's information. He scratched his cheek awkwardly and had no intention of going into the house. It was obvious that he was a little timid.

But seeing Hattori Heiji still at the crime scene, he, as a detective, didn't dare to go in. He couldn't help but cough:

"Hey, Hattori, do you want to come back with me? Will it be possible here..."

"Brother Sakata, I'm fine. It's good that I can learn from Brother Takashi here." Hattori Heiji waved his hand to refuse. He finally had the opportunity to come into contact with such a serial murder case, so he naturally wanted to stay and learn well.

"Well, fine, I'll be leaving first."

Hattori Heiji carefully compared more than ten lists of missing persons and finally found that Tachikawa Arisa, who disappeared a week ago, looked exactly like the unnamed victim, especially the iconic black mole on the tip of her nose.

After hearing the news, he immediately ran to Sosuke Takagi's side, like a detective's right-hand man:

"Brother Yingsi! I know the identity of the third victim!"
