Entering the room, Meng Tianchu stared at Hai Dashan and said in a deep voice: "After the autopsy, it was found that your son Hai Zhuzi fell into the water and drowned after being hit on the head by someone, so your son died of murder!" It's a homicide! ”

Hai Dashan's body trembled slightly, and his lips trembled and asked, "Master... You..., you're not mistaken, are you? ”

Meng Tianchu sighed: "Uncle Hai, it stands to reason that a father will definitely be very shocked and angry when he knows that his son died of murder, and he will be anxious to ask who the murderer is, instead of asking if the person who examined it is mistaken." ”

"I..." Hai Dashan's body trembled even more, and he turned his head to look at Lin Ruofan, not knowing how to answer.

"Anyway, what's going on? Who killed your son? - Did you do it? ”

Hai Dashan's old face turned pale, lowered his head and pondered for a moment, and then slowly said, "Yes... I killed it. ”

Hai Li was stunned, grabbed Hai Dashan's arm and shook it: "Hey! Uncle, you're not joking, are you? ”

Meng Tianchu sat down on the chair and said to Hai Lizheng: "Lord Lizheng, you go out first, and the contemptible people will interrogate the criminals." ”

Haili hurriedly bowed down and agreed, glanced at Hai Dashan again, and then went out of the room.

The guard Zhu Hao was about to close the door, but Meng Tianchu waved his hand to stop it, because he found that when Hai Dashan admitted to killing Hai Zhuzi just now, Lin Ruofan's expression was obviously quite abnormal, although Meng Tianchu didn't want this matter to be really Lin Ruofan's doing, but if this was really the case, then he would not indulge the criminals to go unpunished, although Hai Zhuzi was innocent, it could only reduce the murderer's guilt as appropriate, and the murderer still had to take responsibility for his actions after all.

Murong Yuxue sat aside. Take a pen and take notes.

Meng Tianchu said to Hai Dashan: "You can tell me about the killing of your son." ”

Hai Dashan lowered his head, thought for a while, and said: "That day, the pillar beat his daughter-in-law, I went to persuade him, and he beat me, I was angry with him, and now I heard him say that he was going to sell his daughter-in-law, I feel very sorry for my daughter-in-law, I can't hurt her no matter what, so I made up my mind to kill Zhuzi." So, after the pillar left home. I followed him past the pond. I hit him in the head from behind, knocked him unconscious, and pushed him into the pond and drowned..."

Meng Tianchu listened to it and frowned: "What did you use to hit him?" ”

"I picked up a stick of firewood from the corner of the house."

"What kind of firewood?"

Hai Dashan secretly looked at Meng Tianchu, thought about it, stretched out his hand and gestured, "It's so long, it's the head of the elm tree split." ”

"Where did you hit?"

"Head."

"Where's the head?"

Hai Dashan thought about it again. He touched the back of his head: "This is it." ”

Meng Tianchu's brows furrowed even tighter: "How many hits?" ”

"Once! And he fell. ”

"What about firewood?" .et members hand-beaten.

"Thrown away."

"Where did you throw it?"

"Throw to... I forgot..."

Meng Tianchu snorted. Turning to the conversation, he asked, "When did your son leave home?" ”

"It's dark, it's like... It seems to be about a watchday. ”

"Has he eaten?"

"Didn't eat... I don't think I ate it! ”

"Like? It's only been a few days. You can't remember, do you? ”

"I didn't eat, I didn't eat." Hai Dashan was dizzy by Meng Tianchu's series of questions, and his forehead was sweaty. After listening to Meng Tianchu's question just now, he quickly changed his answer.

"Did he drink?"

"Drunk..."

"He didn't eat, did he just drink?"

"yes, oh no, he didn't drink, he didn't eat that night, so he didn't drink, I remembered wrong."

Meng Tianchu sighed: "You are lying, you didn't kill your son!" ”

Hai Dashan's body shook slightly, and he hurriedly said: "Master, what I said is true!" Really, I didn't lie to you. ”

"Didn't lie? Autopsy, your son has rice and vegetables in his stomach, which have just been digested, indicating that he was killed shortly after eating, and his stomach is full of the smell of alcohol, and there is also vomit from him by the pond, and there is also a smell of alcohol, how can you say that he has not eaten or drunk? ”

"It's... It's the villain's mistake, and the dog seems to have eaten it. ”

"You will say that you have eaten it for a while, and then you will say that you have not eaten it, what is going on?"

"Eaten, eaten... I remembered wrong..."Hai Dashan wiped the cold sweat from his forehead and stammered.

Meng Tianchu ignored this stubble and said: "You said that you hit the ground with firewood, and the firewood was split by the head of an elm tree, with edges and corners, but the deceased's scalp was not broken at all, and the deceased's skull fracture showed that the scars were sheet-shaped, not long-striped, indicating that the murder weapon should be a flat blunt weapon, you said that you hit it with firewood, and the firewood could not form this kind of scar at all, in addition, you said that he fell down after only one hit, but he obviously had two scars on his head, indicating that he was beaten twice." You said that it hit him in the back of the head, but the wound of the deceased was in the left temporal region, even if you remember the part wrongly, but you hit him from behind, and you are not left-handed, and it is generally impossible to hit him on the left temporal part of the ground with a firewood stick in his right hand from behind. ”

After listening to Meng Tianchu's series of questions, Hai Dashan said nervously: "No, it's not the ground, I remember wrong, I didn't use firewood, I used it..."

"Okay, you don't have to make it up, because no matter how you make it up, there is one biggest loophole that you can't lie about - you said that you killed your son in about one watch, but the autopsy proved that your son died in about three watches, two hours (four hours), and it was only a few days, how could you even remember this wrong? I don't know why you want to take the blame for someone else, but you must have your own reasons for taking the blame for this person, so you know the murderer, anyway, who is the murderer who killed your son? ”

Hai Dashan's face turned pale, gritted his teeth, and said in a low voice: "Master, I killed my son, really..."

No matter how Meng Tianchu questioned him, and no matter how inconsistent the crime statement by Hai Dashan was with the facts of the investigation, Hai Dashan always insisted that he killed his son Hai Zhuzi.

Because Hai Dashan's confession contradicted the fact that the autopsy was seized, although he pleaded guilty, which in the Ming Dynasty could have been closed on this basis alone, Meng Tianchu was from modern times, and of course it was impossible to be so arbitrary, so he did not order him to be arrested, but just let Minzhuang control him.

Obviously, Hai Dashan is defending the real murderer, and this murderer is likely to be Lin Ruofan, but now there is no evidence to prove this, what should I do?

Meng Tianchu pondered for a moment and straightened out his thoughts, if it was Lin Ruofan who killed Hai Zhuzi, and the time of death according to the autopsy was in the middle of the night, what would Lin Ruofan and Hai Zhuzi do at the pond at the edge of the village at this time? It's all husband and wife, is it necessary to go to the pond for romance? The pillars of the sea do not look like graceful people.

If the drowning of the sea pillar was done by Lin Ruofan, it is most likely that the sea pillar was killed after a conflict at home, and then the body was moved and thrown into the pond.

Thinking of this, Meng Tianchu already knew how to solve this case. He had to perform a comparative test of the diatoms to find out where the actual drowning was done.

It is certain that the Dead Sea Pillar did die from drowning, and he now has to examine the diatoms in the body of the Dead Sea Pillar to find out whether the dead person really died in the pond, and if not, then the real place of death needs to be found out according to the diatoms.

Diatoms are planktonic single-celled organisms that live in water and can only be seen with a microscope. The drowning person sucks the water into the lungs, and then through the large circulation can reach the internal organs of the whole body, and there are more than 10,000 kinds of diatoms, the types and quantities of diatoms in each body of water are different, if the diatoms in the body of the deceased are consistent with the diatoms in a certain water, it can be proved that the water area is the place where the deceased drowned.

Meng Tianchu re-autopsied the corpse, extracted the lungs, heart and blood, liver, kidneys and other tissues of the deceased Haizhu for diatom testing, and then extracted pond water samples for diatom testing and comparison, and found that the two were different, proving that Haizhu did not drown in the pond at all!

Meng Tianchu conducted a detailed examination of Hai Dashan's house, and took water samples from all places where there was water that could cause people to drown, but unfortunately, none of the water was consistent with the diatoms in the deceased's body.

Didn't the sea pillar drown at home? Could it be that I guessed wrong, the murderer was not Lin Ruofan? If his speculation is wrong, then apart from Lin Ruofan, who else can make Hai Dashan rather admit his guilt and sacrifice his life to protect him?

Meng Tianchu called Hai Lizheng aside and asked him about the people who were close to Hai Dashan on weekdays. Hai Li is saying that there are not many people in the village, everyone is a villager, and the relationship with each other is also good, so I haven't heard of anyone who has a particularly good relationship with Hai Dashan. In the end, he said a few villagers who are usually with Hai Dashan for Meng Tianchu's reference.

Meng Tianchu inspected the homes of these villagers and took water samples for testing, but the results were still very disappointing, all of which were different from the diatoms in the deceased's body.

Where is the real crime scene?

Now he had to cast a wide net, Meng Tianchu took all the water samples in the wells, ponds, paddy fields, and ditches in the village and the edge of the village for comparative testing, and was busy until it was almost dark in the afternoon, and still found nothing.
