Long Zihan nodded and said, "Yes, moreover, the thing that hit the deceased's forehead is the missing high heels." Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

That is to say, after the deceased took sleeping pills, the murderer used the heel of the high heel to continuously hit the deceased's forehead, so that the deceased's skull was not fractured, and the real cause of intracranial hemorrhage was died.

Long Zihan continued: "First of all, people who understand the principle of echo know some acoustic knowledge, and secondly, use the principle of echo to knock on the forehead of the deceased and let the deceased die of intracranial hemorrhage, which also requires a certain knowledge of mechanics. ”

The Chu Yi people had to sigh: "If this is the case, the murderer is too knowledgeable. However, whether this is the reason or not, I think I will go back to my forensic office to verify it. ”

Long Zihan said: "Send these two little guys back, we have to go back to the police station immediately." ”

Sending the child home, the two rushed back to the police station in a hurry.

After repeated inspections and experiments by the Chuyi people, they finally came to the conclusion: "As you say!"

Long Zihan fell into deep thought, and Mo Bei on the side said to himself: "Even if you know how the murderer killed He Yuhan, how can you find evidence?"

Long Zihan said: "Three homicides, three deceased, but He Yuhan's death is the most strange, and now they have found out how He Yuhan died, are you afraid that you won't be able to find evidence?"

"Ding Tingting's case is actually very easy to understand, but how did Sun Yun's case go? We didn't find carbon monoxide in the room, but Sun Yun did die of carbon monoxide. ”

Regarding Sun Yun's case, Mo Bei was very puzzled.

"In chemical experiments, there are many ways to extract carbon monoxide, and there are many containers that can hold carbon monoxide. As long as the murderer has a heart, nothing is impossible. ”

Seeing Mo Bei's eyes that seemed to understand or not, Long Zihan continued: "The oxygen mask used by the patient in the hospital is actually not difficult to get, if the carbon monoxide in the container passes through the oxygen mask and is inhaled by the deceased who took sleeping pills, then, even if the amount is not large, it is enough to cause death." ”

"But the murderer did everything so precisely, leaving no evidence at all, what should we do?"

Long Zihan thought for a moment and said, "Didn't the crime scene of the three cases have all left us to patrol and collect evidence? Remember, in particular, don't let go of the garbage heap. ”

Mo Bei nodded and responded, "I'll go and inform them." ”

The case is still under intense investigation, and the day has passed like this.

The next day, at about 10 o'clock in the morning, Long Zihan was sitting alone in the office, thinking about the case just when he was out of his mind, and the arrival of an "uninvited guest" disturbed his thoughts.

"Hello Long Shao, it's nice to see you again. "The person who came was Miao Yingying, a teacher from the orphanage.

Catching up with Miao Yingying's enthusiastic smile, Long Zihan was a little panicked.

If he could, he really wanted to say: Girl, I'm not so happy to see you.

This girl has to come when he is busy and he is annoying, and it is really unpleasant. He had already made it clear last time, didn't he? Even if he didn't know, didn't she understand it at the time?

However, although he was dissatisfied with her appearance, out of gentlemanly demeanor, he did not show his dislike for this person.

Long Zihan said politely: "Teacher Miao, please take a seat." May I ask if there is something wrong with coming to Long this time?"

Miao Yingying said: "It seems that the last time left a bad impression on Long Shao. However, I feel that I need to explain ......"

As she spoke, she took out a box and said, "Twelve years ago, I was seven years old. Because of a high fever, I lost my previous memory, and when I woke up, I was already in the orphanage. Oh, by the way, it's the orphanage we met. ”

Long Zihan looked at Miao Yingying, not knowing what she was going to do to find herself.

I only heard Miao Yingying say: "When I was sent to the orphanage, all the things I was wearing were here. ”

Long Zihan looked at Miao Yingying in confusion and opened the box, which contained a black and white linen cloth with intersecting straight strips, and this dress was the size worn by the child.

Next to the clothes was a string of colorful beads and a copper coin that had long been out of fashion.

Miao Yingying said: "I hope that Long Shao can do me a favor!"

"You want me to help you find your relatives?"

Miao Yingying looked at the door behind her, and then whispered, "Yes and no! It's an incident I encountered recently, which is related to this memory I lost." ”

Long Zihan asked, "What is it?"

"Recently, there is an old man who often comes to my door, and he has only one purpose, to ask me for his son. ”

Long Zihan didn't ask for extra words, just waiting for her to say it herself.

"According to him, he is my adoptive father. One day, I took their only son to play in the woods and never returned. They found some traces of wild beasts in the woods, and although there was no blood, her wife thought that her son must have been more than lucky. Because her wife was already in poor health, she was hit so hard that she died within a few months. ”

Normal people will think that when two children encounter any beast, there must be no room to escape and resist.

And they have disappeared for so long, most people will think that if they were still alive, they must have come back a long time ago.

The adoptive father was unwilling, he always felt that his child was still alive. So, over the years, he never gave up searching. Finally, not long ago, he found me. He said that these were the clothes and accessories that my adoptive mother had made for me. I don't have that memory, so I can only take these and ask Long Shao for help. ”

Long Zihan asked suspiciously, "Why didn't you say it that day?"

Miao Yingying's face was slightly ugly and said: "This is always a private matter, Long Shaogui is busy, I can't ask you in front of Mrs. Zun, lest it cause unnecessary misunderstandings." ”

Long Zihan sighed and said, "It seems that it is really a misunderstanding!"

It's because he himself is too narcissistic and misunderstands other girls, but fortunately he didn't make any jokes.

Thinking about it like this, he felt a little sorry for Miao Yingying.

His expression softened, and he asked, "Have you tried to ask the director and the person who took you to the orphanage about the situation?"

"I found it, but the person who sent me to the orphanage has long since died. The dean said that I had a high fever and was covered in injuries. And the aunt who sent me here found me lying unconscious on the way to the backyard of the orphanage, so she sent me in. ”

Long Zihan said simply: "To be specific, I will tell you what you know and what you have found." ”
