Guo Lao continued: "You straighten your legs - naturally put them down, and then touch your kneecaps." ”

The three of them followed Guo Lao's prompt, straightened one leg, put their feet on the ground, and then touched their kneecaps with their hands.

"Old Guo, I understand what you mean." Ouyang Ping seemed to have an understanding.

"Ouyang, tell me about it."

"The kneecap is connected to the thigh bone and the lower leg bone, and when the leg is straight, only when the leg is straight, and only in the front, the weight separates the kneecap into its present state, and when the leg is straight, the kneecap can move up and down, left and right, and it is difficult to break the kneecap when the kneecap is not fixed. Guo Lao, am I right? ”

"Ouyang, what you said is very good; What's more, in the case of flesh and skin, it is impossible for any heavy object to smash the knee into several pieces, unless it is the pressure of an extraordinary weight - if it is an extraordinary weight, then the kneecap will not be divided into several pieces, but will be shattered; Moreover, there is another source of lethality in the deceased's body - the murderer's only purpose is to kill the deceased, and since the deceased has already been killed, why should he hit the deceased's kneecap and the junction of the kneecap and the calf bone? Vent your inner hatred? It seems that there is no need for this, if the murderer wants to vent his inner hatred, there are many options, such as hitting the deceased's head and face with a heavy object, and stabbing the deceased in the chest with a murder weapon, why choose this position alone? ”

The three of them can be regarded as an eye-opener, and after Guo Lao said this, the three of them seem to have some clear understanding of the case.

"Guo Lao, I have a question, I don't know if to ask?" Han Lingling asked.

We all know that Han Lingling usually doesn't speak much, but as long as she speaks, it must be well thought out. After working by Ouyang Ping's side for so many years, she has gained a lot of knowledge, and under the influence of Ouyang Ping, she is more and more able to think about problems.

"Xiao Han, ask!"

"Can a heavy object break bones when a person is in a living situation, that is, when he is wrapped in flesh and skin?" Han Lingling looked at a photo in her hand and said, this photo is a photo taken after the corpses are assembled.

"Xiao Han! That's a good question, actually, I've already answered it, and I'm just not direct enough -- not direct enough. In the case of a living body, it is impossible for a heavy object to break the bones wrapped in the flesh - the weight first comes into contact with the flesh, and the flesh will break down a lot of force. ”

"Old Guo, tonight, we took the liberty to disturb you, it was Han Lingling who thought of it, and she found some problems in this autopsy report."

"Since the bones cannot be broken by heavy objects in the case of a living person, how was the lower leg bone of the deceased broken in this case? Why did the killer do this? Han Lingling still had doubts, and the tentacles of her thinking continued to extend into the depths.

Guo Lao stood up and picked up a coat from the back of the chair: "Let's go, I'll go with you, and when I see the victim's body, our analysis will be more convincing." On the way, you tell me about the case, and I'm very interested in this case. ”

"It's so late, is that appropriate?"

"I usually rest around eleven o'clock, go, don't bother. Wife, I'll go to the bureau with Ouyang and them. You rest first! Don't wait for me, I have the key on me. ”
