Speaking of this, Chengnan suddenly remembered something, and said with a smile: "By the way, I glanced at the deceased just now, he should have died between ten o'clock and three o'clock in the morning, and during this time I slept in the dormitory, my roommate can prove it, of course, if you want to suspect that we both have a share, then I have nothing to say." ”

Liu De didn't expect Chengnan to know a lot, so he couldn't help but glance at Chengnan more, and praised: "I can't see that you know a lot, as for the murderer, you can rest assured that we will naturally investigate as a policeman, and we will definitely not wronged good people, and the police are talking about evidence." ”

As soon as Liu De's words fell, a policeman next to him walked over with two transparent bags in his hands and said, "Team Liu! The preliminary results of the inspection are out! ”

Liu De turned around and said, "Tell me about the situation!" ”

The policeman handed over two transparent bags and said: "According to the preliminary examination of the coroner, the man was first knocked unconscious, then stabbed to death with a sharp weapon, and eleven wounds were found in his chest, and the murderer was so cruel that after the death of the deceased, he also used a sharp weapon to split his body in half and cut off his hands and head. ”

"Oh? Did the murderer leave any clues? Liu De picked up the two transparent bags handed to him by the policeman just now and looked at them, and found that they contained a toothpick and a handful of black hair and asked.

The policeman pointed to the two evidence bags in Liu De's hand and said: "We only found this toothpick next to the window, and we found this pinch of black hair on the ground, this black hair has not been examined and I don't know what kind of hair it is, but according to my judgment, it should be animal hair, as for the others, nothing has been found for the time being." ”

Liu De looked at the things in his hand and asked, "I heard Liu Mei say just now that this may be a closed room murder case, is it related to these two things?" ”

The policeman glanced at Liu Mei and said: "Well, we just recorded a confession for the other two witnesses here, they said that this door was indeed locked at the beginning, but it was kicked and broken later, and the windows were also intact and locked, this should be a closed room murder case, as for whether these two items are related to this secret room murder, it is not clear for the time being, so how the murderer left this secret room is not clear."

The policeman suddenly remembered something and patted his head and said, "Oh, by the way, we just found that the bolt hole in this window seems to have been artificially enlarged, presumably to make it easier for the bolt to fall, and nothing else is wrong." ”

"Okay, I see, you can have the body carried away! Clean up the scene, seal the house, and don't allow anyone to enter without the permission of the police! Oh, by the way, send someone to check everyone in this school and record a confession. Liu De finished commanding, and then waved his hand.

"Okay!" The policeman went into the house again, and after a while the dead man was carried out by several policemen.

After Liu De watched the corpse being carried away, he turned to Zhang Mei and said, "Okay, I will leave Zhang Mei's matter to you and Xiaogang to be responsible." You take Xiaogang over tomorrow to visit the people inside to see if there are any clues, I will go back today and report to the top, there have been two murders here in a few months, and then we are tired. ”
