Clicking on the test description of the deceased's wounds, I saw that there was not much information in it, but it was written: After comparison, the two deceased's wounds were caused by an unknown sharp tooth-type metal. Pen Fun Pavilion www.biquge.info Until now, this metal has not been seen anywhere. However, there are metallic properties.

The wound was half an inch deep, straight into the aorta, and no hole was seen to penetrate the vessel. The initial guess is that the blood was directly drained by some kind of vacuum container!

"Shhh Seeing this, Zhou Yu gasped. This murderer is too inhumane, and he directly drains people's blood!

At this point, it's gone. opened a folder of on-site testing, and the contents made Zhou Yu a little excited. His guess was confirmed by what was inside.

Sure enough, the first paragraph in it was what he wanted to know: after the second sampling at the scene, it was found that there were small holes like screens on the vellum paper on the window sash at the scene of the crime in the West District, and after many tests, it was confirmed that there was a residue of anesthetic fog on it!

"That's right, this murderer can't draw people's blood unknowingly." , Zhou Yu had a smile on his face, his guess was right.

Anesthetic fog, the amount is still a lot, this thing can't be obtained by ordinary doctors, obviously this person is very powerful! In addition to the traces of damage to the inner door latch, there are also cotton wool silk similar to ropes left.

And the on-site evidence collection of the children in the eastern district made Zhou Yu confused. Because the child was killed by his mother's side. And neither the window nor the door, there is no sign of anyone entering from the outside. There are also no traces left by the anesthetic aerosol.

"We were also curious about how there were no traces of anesthetic aerosol at the scene. For this reason, I ran twice, and the materials retrieved were undetectable. Professor Xu said helplessly.

"What about wounds? Is it the same material? Zhou Yu spoke, and clicked on the next folder casually. It was the picture folder of the scene, the miserable white of the tourists and children, the black eyes that were not blind, and Zhou Yu shuddered when he saw it!

"It's this weird, same material. Judging from the technique, this one is not as sophisticated as the adult's wound! Punctured the aorta, right perforated! ”。 Professor Liu replied.

After flipping through other information, he didn't find anything useful, so Zhou Yu said goodbye. In just two or three days, with this result, it is already very good!

I wanted to go find Guo Changli, but I didn't expect him to be outside to investigate.

"It's really desperate!" , Zhou Yu is not unimpressed, but this is like looking for a needle in a haystack, a blind man touches an elephant, and what he touches is what he is, without a purpose. I don't know what Professor Tao thinks, so he doesn't tell Director Guo about his goals.

"Seen it?" , Professor Tao didn't know where to come out, holding a thread-bound book in his hand that he didn't know when, looking like a master!

"When did you change to school?" , Zhou Yu quipped.

"What do you mean by being reed? I'm a teacher myself. Professor Tao pretended to be angry and slapped Zhou Yu twice on the head.

"Ahem, it's stupid to fight again! By the way, why didn't you tell Director Guo about the target of the investigation? Zhou Yu was a little puzzled.

"I still have something to be sure." Speaking of the case, Professor Tao also frowned. He wasn't completely sure about it now, because the two scenes seemed to be very different!

"You think slowly, I'll go out for a walk." , Zhou Yu plans to take another walk and see how people's mood is now.

Maybe Director Guo and the others have stepped up patrols, or they have learned that the task force is coming, and the residents in the city are not as impetuous and panicked as yesterday, and many small shops are open again.

Zhou Yu walked along the street, and unconsciously came to the gate of the deceased child in the Eastern District. At first, I was strange, why was there crying inside, but I heard an aunt next to me explain that this was the house where the crime occurred!

Walking in, I saw that a tablet had been placed on the kang in the lobby, and dried fruit and food had been placed. Since the body was still in the public security bureau, the family had no way to mourn.

It was the child's grandmother who was crying, and the child's grandfather and father were also full of sadness, and their eyes were red.

"The devil, the great devil is coming! Haha, kill the devil, kill the devil, give me back my child! As soon as Zhou Yu wanted to pour two drinks like the residents who went to learn to worship, he heard the terrifying scream coming from the next room!

"Thank you, this is the mother of the child, crazy again! Excuse me! The child's grandfather asked his son to go in to appease his daughter-in-law, and said to Zhou Yu apologetically.

"It's okay old man, although the child is gone, but your son and daughter-in-law are still there, keep your body!" , Zhou Yu still comforted him.

"Alas, it's fine to come back from the Public Security Bureau, but as soon as I arrived at this house, I started yelling like crazy! I can't help it. The old man smiled bitterly, and his stiff back made him look as if he was carrying a big mountain!

"Can I go in and have a look?" , Zhou Yu asked softly.

"Yes, don't be scared by my daughter-in-law." , the old man did not refuse.

Zhou Yu entered the West House and found that the male owner was sitting on the bed with his wife in his arms at this time, patting her back while comforting!

But what Zhou Yu didn't expect was that the moment the woman looked up and saw Zhou Yu, her eyes suddenly widened and she screamed: "Big devil!" The Great Devil is coming! Give me back my child, big devil! She screams and scratches her husband with her hands!

"Mayi, Mayi, that's a guest, not a big demon, quiet, quiet!" Her husband was taken aback and hastened to comfort her.

"The devil, the great devil!" , her husband's comfort was still useless, I saw that she just pointed at Zhou Yu with her finger and screamed in horror!

Zhou Yu had no choice but to exit the room.

Seeing the old man Zhengxiang come in to see the situation, Zhou Yu grabbed the old man, "Old man, take a step to speak." ”

The old man followed Zhou Yu to the courtyard and asked suspiciously, "Is there something wrong with Mr." ”

"Did your daughter-in-law really have any problems when she came back from the Public Security Bureau?" , Zhou Yu asked.

"The other morning, when I woke up, my daughter-in-law saw that the child was cold and crying without a sound! Later, we were taken to the public security bureau by the police, and when we came back, we were fine. Just as she got back into the house and sat on the bed, she started screaming in terror! ", the old man recalled.

"Sit on the bed and start screaming!" , Zhou Yu looked at the house and began to think about what aroused her uneasiness!

There is nothing outside the window, the window frame and sash are aluminum alloy, and the sealing material used is kraft paper, which is commonly used here. This material is cheap, opaque, has a certain amount of lighting, and changes every year. There is a large temperature difference between day and night, and it is easy to shatter with glass.

It can be said that it is impossible to enter from the outside of the window, and the inside is locked. So, what exactly did she see?
