The reason is actually very simple, because we are all adults who are taller than 1.8 meters, not children who are four or five years old.

Yes, such a simple logic, Fang Yuan and I didn't expect that the length of the hemp rope would not change, but we were not the ones who were bound.

On the way, I made a mathematical formula in my notebook, a two-meter-long hemp rope, tying a child about 110cm to 140cm tall, coupled with its average size, the result was eye-catching.

The result was correct, that if the hemp rope had been tied to a child of this size, the bloodstained ground would have been on the side of the child's hand.

After returning to the Criminal Investigation Brigade, I did the equation several times on my desk, and the answer was the same, and it turned out that the hemp rope, which was about two meters long, would only appear correctly in the child's hand when the blood stain was tied to a child of that size.

"What? You want to be a mathematician?"

Just as I was about to sort out the materials and get up and knock on the door of Fang Yuan's office, a cold female voice suddenly sounded from behind me.

I turned around and saw that it was Lin Xi, who was standing in front of me in a long white down jacket with a large stack of papers.

Lin Xi's height is about 1.75 meters, plus her pair of ten-centimeter high heels, her height looks about the same as mine, so the moment I turned around, I saw Lin Xi's face that was only three or four centimeters away from me, and I was so frightened that I sat back on the stool directly.

"Eldest sister, people are scared to death. ”

I patted my chest, gave her a blank look, and said speechlessly.

Maybe it was because I stayed with Lin Xi for a few hours in the forensic hospital last time, and I felt that this woman was not so difficult to get along with, so I naturally said this sentence.

"Don't do anything wrong, don't be afraid of ghosts knocking on the door, Captain Fang told you to go in, I'll go first." Lin Xi took the stack of documents expressionlessly, said coldly, and wiped it directly past me, I don't know why, every time I see her, I always smell a fragrance.

Although I am not an insider, I also know that forensic doctors are not allowed to wear any cosmetics or even perfumes while they are on duty, but she ......

I looked at Lin Xi's back, and I always felt that I had smelled that fragrance somewhere, but where it was, I couldn't remember.

Five minutes later, I pushed open Fang Yuan's office with my notebook, and as soon as I entered the door, I saw that he was fiddling with his old-fashioned big-headed computer, and his hands were still very rusty on the keyboard, it seemed that Fang Yuan didn't usually play with computers.

Seeing me walk in, Fang Yuan only glanced up at me slightly, and then asked me to take a closer look at the stack of materials on the table.

I nodded, sat down in front of Fang Yuan, picked up the stack of materials and looked at it.

Immediately after, I opened the first document on the table, which was an autopsy report, and the moment I saw this report, I immediately knew the reason why Lin Xi didn't want to write the autopsy report.

Because of this autopsy report, the font is twisted, and some words are even squeezed together, to be honest, this report is not as good as the homework written by my five-year-old nephew.

I sat at Fang Yuan's desk and flipped through it for about fifteen minutes before I raised my head and looked at Fang Yuan in disbelief.

To be honest, no one wants to believe the facts written on it to anyone who shows this post-mortem report.

"Finished?" Fang Yuan's gaze was suddenly pulled back to me from the front of the computer screen.

"Boss, this ...... How is this possible...... They are ......"

The latter nodded, and said to me with a solemn face: "Yes, the body of the boy found in the dam in the eastern suburbs, and the flesh of the adult man in his flute, are indeed father and son. ”

I swallowed, my heart felt like it had been hit by a 30-ton truck, and I couldn't help myself for a long time.

If, as the autopsy report suggests, the owner of the pieces of meat and the boy's father are the same person, how cruel must the murderer be?

Thinking of this, my face couldn't help but turn red, I was a little angry, I couldn't imagine how perverted the murderer had to be to commit such a dehumanizing crime on a pair of fathers.

Another test report was made on the powder in the deceased's stomach, which showed that the powder found in the deceased's stomach pouch should be human bones, Lin Xi tried to verify the DNA of these bone meals, and it turned out that these powders made from bones belonged to the father of the deceased. ”

Listening to Fang Yuan's words, I felt as if I had been struck by lightning.

"Powder, bone meal, bone ......," I muttered in front of Fang Yuan.

"These powders should have been fed to the child by the murderer at the beginning, but for some reason, the murderer finally let the child swallow those human bones, and the more than thirty bones found in the cellar, if you and I are not wrong, it should be the murderer who stayed and continued to stuff the things into the child's stomach, but the child was still too small and the stomach was ...... at all."

Fang Yuan didn't say any more, he was extremely shocked, but it was not difficult to hear from the tone, Fang Yuan was also very sorry for what happened to the father and son.

"Regarding the process of the case, don't let anyone know, this is the media era, as long as the slightest rumor leaks, the outside world will set off a big wave of exaggeration, and the panic that will be brought to the society at that time can be imagined. ”

I looked at Fang Yuan, nodded with a blue face, in fact, to be honest, according to Fang Yuan's personality, he would not care about these things, he was just afraid that he would be known by the above, and then compress the time for us to solve the case, I think Fang Yuan understands better than anyone else that the above is concerned about social issues, and what we care about is the whole case itself.

"Also, the identity of the father and son has not been investigated clearly until now, Li Yan has just returned, and the people I sent to investigate have returned in vain, I will give you a task, within three hours, I want to see the details of the father and son. ”

"Good. ”

I didn't think about it, so I replied directly to Fang Yuan, to be honest, this case had a really big impact on me.

After leaving Fang Yuan's office, I went directly to Li Yan's computer desk and turned on his computer while he was in the toilet.

I remember that when I was in the car, I saw a photo of this child and his father, and at that time I thought that Li Yan had found the information of the father and son, and he couldn't show it to me at that time, after all, Fang Yuan was the leader of our three groups.

However, Fang Yuan didn't seem to know the information of the father and son, since Li Yan had already found this group photo, then that means that he had a high probability that he had already checked their information, I don't understand why he didn't submit it to Fang Yuan in time.

After I turned on his computer, I clicked on a folder on my desktop called the Eastern Suburbs Dam Case, and the photo immediately came into view.

As soon as I flickered around, a black icon came into view.

I've seen this kind of icon on someone's computer, and he once told me that if you see this icon on a certain computer, then I must not mess with this person, because this kind of thing only appears in the computers of some hackers, yes, if I remember correctly, this thing should be some kind of Trojan horse software.

And on the side of this software, I even found a software that simply queries household registration information and face comparison.

"Don't look for it, if I had the information of the father and son, I would have taken it out a long time ago, when I was in the capital, the head sent me an email, the email was a photo of the child's death, at that time the head had only one request, hoping that I could find the child's true identity, but the police database is limited, and only the person with a criminal record can be displayed, so I didn't find any information, as for this photo, I asked a hacker friend to find it on the Internet. ”

At this time, Li Yan patted me on the shoulder, and that huge face instantly appeared in front of the computer screen.

"Since you have found this photo on the Internet, you can also search for this person's IP address according to the Internet, right?" I raised my head suspiciously, looked at Li Yan, and said slowly.

The latter shook his head and told me that he did find the IP address, it was in an Internet café in the city, but the time when this photo was sent was in May of the previous year.

I looked at Li Yan's eyes, and when he said these words, he didn't seem to take it seriously, but I had a feeling that Fang Yuan and Li Yan were ...... The two of them seem to be hiding something from me.

I nodded, and then slowly sat up from Li Yan's position, before turning around and leaving, I thought about it, and finally stopped, and said in a dull voice: "Don't put this kind of icon on the desktop in the future, it's okay for your own people to see it, if you show it to others, you may only be able to be a hacker in the future." ”

I think Li Yan knows better than me that except for a very small number of computers in the network supervision department, such icons are allowed to appear, and our police handling cases are not allowed to hack into anyone's computers.

"Don't worry, it's just me who wants to, and I haven't been discovered. Li Yan listened to this, and immediately said to me with a smile.

After leaving the Criminal Investigation Brigade, I stood at the door for a few minutes, and finally I chose to take a taxi to the missing person department to inquire about the recent missing person case.

The child's death was three days ago, but according to the digestion of his stomach, the child's disappearance should have been seven days ago, and his father's disappearance may have been earlier or even at the same time, seven days, unless the man has no job, no relatives, no lover in the city, otherwise, there must be news of the man and the child in the register of the missing person.
