Chapter 16 Chapter fifteen

It was already late at night, and in the forensic laboratory, Gao Dong stood silently in front of this patchwork bluestone slab. After a long time, he called forensic doctor Chen beside him: "Have you found out which floor the slate fell from?" "Not yet, but there should be a result tomorrow." "What are the length, width and weight of the stone slab?" Forensic Chen took a report and read: "The length is 85 centimeters, the width is 61 centimeters, and the weight is 63 catties." Gao Dong nodded. The first thing that can be confirmed now is that even if Hu Haiping died of murder, the murderer was standing on the rainshield and throwing the slate down. It is impossible to stand inside the window.

It takes a lot of effort to lift the 63-jin stone slab, not to mention the cement rain-shield that extends more than one meter outside the building. Lifting the stone slab and throwing it forward one and a half meters is the ability of Popeye. Ordinary people can't do it at all. Gao Dong pursed his lips: "There are traces of glass glue on the long side of the stone slab. It seems that the slate was originally fixed on the cement rain shield outside the building." Forensic Chen nodded: "Let's go upstairs to check again at dawn tomorrow." Gao Dong said: "By the way, have you noticed that this stone slab is not a fixed one?"

Forensic Chen approached the stone slab, looked it over carefully, and said, "Boss, you should look carefully. The slate was originally cracked into four pieces. There are several cracks running through here. The four slabs should be glued together with construction glue. It’s made up. It’s probably the tile glue used for decoration, which is specially designed to bond stone, and it’s very strong.” On the cracked stone slab, you can clearly see several penetrating lines, which divide the slate into four slabs of about the same size, which are then glued to each other with tile glue and reattached to form a whole slate.The tile glue is very strong, so when the stone slab fell to the ground, it broke into several pieces, and many of the places that had been cracked and rebonded before were still in a bonded state and did not crack.

Gao Dong said: "One more thing, look, one side of this bluestone slab has been painted a khaki color." "Yes, but what's the problem?" Gao Dong shook his head distressedly: "Judging from the current situation, there are several doubts. First, how could there be a bluestone slab on their building? Second, what is the purpose of the slate? Third, what is the purpose of the slate? What is the purpose of the glass glue on it? Fourth, why is the stone slab in a broken state, and who used tile glue to bond the stone slab together? Fifth, why did the other side of the stone slab have to be painted?"

Forensic Chen asked cautiously: "Boss, do you suspect that this is not an accident, but a murder?" Gao Dong looked at him nonchalantly: "What do you think?" Then he smiled flatly, "Now that Wang Baoguo's case is at the forefront, and now that Hu Haiping is dead, I can only say that it was an accident." "I'm still the same as before. I've never heard of such a method of murder. You stand upstairs, and when the murdered person walks downstairs, you suddenly throw a heavy object down to kill him. This method of murder It’s too unreliable, the success rate is too low, and if you don’t kill it, the consequences will be very serious.”

"But if it's not murder, then the doubts about this stone slab—no, it can't be said to be suspicious now, but there are too many unusual places. This is not an ordinary bluestone slab. If it is a flowerpot, or an ashtray It fell and just killed Hu Haiping, so it is very reasonable and completely in line with the judgment of an accident. But the murder weapon is a big stone slab, how can there be a bluestone slab coming out of the floor?" Chen Fayi coughed and said, "Boss, but think about it, if someone really threw this stone slab and killed Hu Haiping, how could he have such good eyesight? There was a time from when the stone slab was thrown to the ground. How could there be such a thing?" Coincidentally, the murderer wanted to drop the slate to hit Dean Hu. When he dropped it, could the murderer just hit him? The width of the slate is only more than 60 centimeters, and it may not land horizontally when it falls. General experience and heavy weight One end is tilted down, so the falling angle of the stone slab is inclined. I estimate that the horizontal projection width is about 40 cm. That is to say, President Hu must be impartial. Within a narrow area of ​​ten centimeters. If he walks 40 centimeters more, or walks 40 centimeters slower, the stone will not hit him, and even if it hits him, he may not be killed. If that is the case, how can Dean Hu let the murderer go? ? The murderer must have known the consequences."

Gao Dong gave a hypothesis: "It's easy to do. For example, if the murderer yelled 'Dean Hu' upstairs, then according to human instinct, Hu Haiping would naturally stop and look up. Right in the head." Forensic Chen smiled awkwardly, he did not expect Gao Dong to draw up such a "wonderful" criminal idea.Although this assumption was possible, he thought it was funny when he imagined that scene.Someone calls your name, and when you look up, a huge stone slab falls down and smashes you flat for no reason. This kind of plot is hard to happen in reality. Gao Dong thought for a moment, then shook his head again, denying his hypothesis: "What I said just now is not reliable, if someone calls you upstairs, you must have stepped back a few steps and looked upstairs. You can’t see the upstairs from the place one step away from the rainshield. Besides, if you call “Dean Hu”, there is no guarantee that Hu Haiping will stop and look up. Now we are just guessing, and we will wait for tomorrow’s survey Let it end. I hope this case is an accident." He raised his eyes, looking a little tired.
