Meng Tianchu took the white cloth covering the corpse, asked Wang Laohan and his son to help take off all the clothes and pants of the corpse, and turned his back to take out a scalpel and a bone saw, because the focus of the dispute between the two sides was whether the collision of Boss Zhang's head was the direct cause of death, so he decided to go straight to the topic and dissect the head.

He first carefully shaved off all the hair with a razor, observed the surface of the scalp, and sure enough, there was a thumb-sized subcutaneous hematoma area in the occipital part of the back of the head, and made an arc incision from the back of one ear through the top of the skull to the back of the other ear with a scalpel, and turned the scalp back and forth to expose the cranium, and there was a clot in the corresponding part of the occipital hematoma in the back of the head, and the blood clot was wiped off, and no bone damage was found at the corresponding skull.

At this moment, Meng Tianchu's heart was already roughly low, according to the facts of the case, Boss Zhang died the next morning after being injured, there was a process, so if Boss Zhang died of this trauma, it was likely to die of a cerebral hemorrhage. This hemorrhage is nothing more than epidural hematoma, subdural hematoma, and subarachnoid hemorrhage. The epidural hematoma, almost all of which are related to linear fractures of the skull, and now no skull deformation or fracture has been found, and epidural hemorrhage can be basically ruled out, and now it is necessary to see if the inferior cavity hemorrhage or subarachnoid hemorrhage is formed.

Meng Tianchu used a fine-toothed bone saw to make a circumferential shape along the front and back to cut open the inner and outer plates of the skull, and remove the skull. Upon examination, no hematoma was found on the epidural. After telling everyone about the examination, he continued the dissection, cut the sagittal sinus along the midline, found no blood clot, and then cut the dura mater and the anterior end of the cerebral sickle along the serratus margin and pulled it back to separate from the arachnoid membrane, exposing both cerebral hemispheres, and after observation, there was no hemorrhage in the dura mater and subarachnoid space.

Now, Meng Tianchu has concluded that there is no direct causal relationship between Boss Zhang's death and his head hitting the bench. The impact only caused Zhang Laoda's posterior cerebral subcutaneous hemorrhage, but did not cause fractures or intracranial hemorrhage.

After Meng Tianchu gave a brief explanation, Zhang Laohan and his son Zhang Laoer certainly didn't know anything about the mechanism of death caused by intracranial hemorrhage, but they clearly saw that there was no fracture on the skull. So the fierce momentum of the two just now wilted all of a sudden.

Wang Yi, Wang Zhutou and Song Xiangyu looked at Meng Tianchu with excitement on their faces, and looked at Meng Tianchu with gratitude and admiration. If it weren't for the fact that the dissection hadn't been completed at this time, Wang Zhutou would probably have knelt down and thanked Meng Tianchu for his kindness in clearing his grievances.

Zhang Lao Er drooped his head and said, "Since my brother didn't die on the bench, is it true that he has run out of life and accepted it for the king of Hades?" ”

Of course, the ghost theory was made up by Meng Tianchu, and after listening to Zhang Laoer's words, he said: "It is not difficult to find out the cause of your brother's death, let's continue to dissect, we will definitely find a reasonable explanation." ”

Meng Tianchu then removed the brain, and after examination, no damage or lesions were found, and the possibility of death due to trauma or lesions in the brain was ruled out.

Meng Tianchu's Y-shaped cut open the chest and abdomen of the deceased, cut open the sternoclavicular joint, removed the sternum, and exposed the chest cavity, and Boss Zhang's fat heart immediately caught his attention. Under normal circumstances, a person's heart is generally about the size of a person's fist, but Boss Zhang's heart is almost the size of two fists, and the left ventricle is hypertrophied and the left heart chamber is very narrow. Based on this, Meng Tianchu preliminarily determined that Boss Zhang may have died of hypertrophic cardiomyopathy.

This kind of patient generally does not have any signs of heart disease before death, and under the influence of some external factors, the heart is induced by electrical disorders, resulting in ventricular fibrillation and death.

Then, Meng Tianchu dissected the neck according to the forensic autopsy routine, and then dissected and examined all organs, everything was normal, and no lesions or injuries were found.

After the autopsy, Meng Tianchu pointed to the fat heart and said to Zhang Laohan: "Your son died suddenly because he had a heart twice as large as the average person, and the quarrel and emotional excitement induced the electrical disturbance. ”

Zhang Laohan and his son Zhang Laoer naturally don't understand the death mechanism of this disease, but when they see this fat heart, no matter how they look at it, it's not normal. I remembered that after Boss Zhang hit his head at that time, he said that he was uncomfortable, and it was late, so he went back to his room to sleep without eating, so he couldn't sleep. I couldn't help but believe what Meng Tianchu said.

Zhang Laohan said: "Then didn't my son die in vain?" ”

Meng Tianchu couldn't cry or laugh: "Your son's death has nothing to do with anyone, it was caused by his own illness, so you can't blame others." Of course, it is not to blame Wang for catching the head. Therefore, it makes no sense for you to stop at the gate of the yamen. ”

Zhang Laohan looked at his son Zhang Lao Er and sighed: "Child, let's carry your brother's body back and bury it." ”

Meng Tianchu said again: "The dispute between you and the Jiang family over the drainage of the eaves, Wang Zhutou's mediation is reasonable, you have to ask the Jiang family to demolish the eaves and let the rain wet their houses, so be it, after all, their eaves extend to your territory, they are at fault first, but it has become a fact, the villagers in the two hometowns, look up and don't look down, you should tolerate each other, let them compensate you with some silver taels, and then pay for a drainage canal to lead the rainwater to your yard to discharge, what do you think?" ”

His sons are dead, and Zhang Laohan has no intention of dwelling on these trivial matters anymore, and what Meng Tianchu said is also fair and reasonable, and there is one more compensation than the last mediation plan, so he nodded and agreed.

Meng Tianchu struck while the iron was hot, and assigned Wang Zhutou and Song Zhukuai to follow them to carry the corpse back, and immediately mediated. The Jiang family was also sympathetic when they saw that the Zhang family had died, so the mediation quickly reached an agreement, and the Jiang family compensated the Zhang family with six taels of silver at one time, and paid for the construction of a drainage canal under the eaves to drain the rainwater out of the Zhang family's yard. The case was closed.

When the headhunter Wang Yi and Song Xiangyu returned to the yamen, Meng Tianchu was tidying up in the inner yamen. Seeing that the two of them had returned, Cai Zhao, the magistrate, summoned the adjutant of the whole yamen, the six-room scribe and the third-class officer, and solemnly introduced his new criminal master.

As soon as Meng Tianchu arrived in Renhe County, he solved a big case and helped Cai Zhixian relieve the siege, and this matter had already spread throughout the entire Yamen, so as soon as Cai Zhao introduced it, everyone shouted sky-high! Among them, there are those who are sincerely admired, of course, there are those who are aimed at Cai Zhao's face, there are those who are half-hearted and perfunctory, and there are those who are good at taking advantage of the cold under the big tree.

Then, Cai Zhixian ordered a banquet to be held in the best restaurant in Renhe County, "Wanghai Building", to make up for the etiquette of inviting the famous master of the penalty, and second, to celebrate the headache of the mortuary case at the Yamen Gate was quickly and successfully solved.
