Chapter 1269

The man pressed by Niza stiffened his body, incoherently trying to prove that his family didn't know.

Mu Zhiyang and the others looked at him without any sympathy. It was obvious that he couldn't explain it clearly; it was just that the more he said, the more mistakes he made.

"Proving existence but not non-existence" is one of the important principles of law and also a basic concept in logic. It's like if you want to prove that dragons exist in the world, you only need to take a photo of a dragon, or at most find a dragon. But what should you do if you want to prove that dragons don't exist in the world?

The suspect chattered in Malay, and Zhong Renlong and another translator explained as much as possible to Liu Jinghui and the others.

Jiang Yuan listened as best he could.

From his perspective, this suspect in front of him was basically the killer without a doubt. Whether he denied it or confessed to the problem wouldn't change Jiang Yuan's view.

As for the others, they wanted the suspect's confession more.

In the eyes of outsiders, the killer voluntarily confessing to this matter is still very important.

It's a pity that the subjects studied by forensic experts usually aren't very proactive.

Jiang Yuan just specially reminded: "It's not easy for him to do this case alone; there should be accomplices."

Niza heard this and immediately increased the intensity of the interrogation.

Soon, two police officers walked into the dense forest again under Niza's order.

"He hid a knife in the woods." Zhong Renlong came over to explain.

Jiang Yuan nodded. This could explain why there were no signs of fighting in the black-faced manager's room, but... Jiang Yuan asked again: "Is he familiar with the He family rubber plantation?"

Zhong Renlong understood: "Not familiar, so accomplices cannot be ruled out."

Several people exchanged thoughts quickly, taking advantage of the time when the suspect had just been caught and was exhausted, and kept pressing information out of him.

At the same time, Green Pine Farm, which had long been surrounded, began to be isolated.

The suspect who was being interrogated suddenly panicked and started shouting again that "you don't have a search warrant."

Niza just sneered: "You were caught at the scene; what search warrant do you need."

Having said that, he wasn't in a hurry to interrogate others on the farm. As far as the current situation is concerned, squeezing this Tarzan is enough.

Jiang Yuan walked around the living area and work area of Green Pine Farm, and then looked at the dormitory of the arrested suspect, before returning to the crime scene of the He family rubber plantation to perform further autopsies.

It's not that Green Pine Farm doesn't need investigation, but Jiang Yuan couldn't be in two places at once. No matter from which angle you look at it, performing an autopsy first is the most reasonable.

In modern criminal investigation, the component of criminal science and technology is becoming heavier and heavier.

Especially in the current situation, the suspect has been found, and the direction of the case is gradually becoming clear, so the work of criminal science is becoming endless.

Niza quickly dispatched personnel from the police station to Green Pine Farm to conduct an investigation.

The suspect's residence must be turned over, including the areas where he often worked, as well as various surveillance videos within Green Pine Farm, all of which must be collected.

By the time Jiang Yuan finished the basic autopsy and the corpse was put into a body bag and sent away, the other two suspects in the He family rubber plantation, mechanical repairmen He Jun and He Cheng, were also arrested.

These two were also on the list of 4 people Jiang Yuan screened through the video.

"Accumulated grudges plus interest entanglements." Zhong Renlong summarized the information from all sides and explained it to Jiang Yuan and Liu Jinghui.

"The two suspects in the He family rubber plantation are both surnamed He. Is it an uneven distribution of benefits among the same clan?" Jiang Yuan guessed casually.

"There are reasons for this." Zhong Renlong himself was Chinese, so he said: "The current owner of the He family rubber plantation, He Quan, belongs to the same clan as He Jun and He Cheng. Calculating it, it's about the relationship of a distant cousin, and they are of similar age. The three of them were even classmates in Chinese school together."

Zhong Renlong: "He Jun and He Cheng didn't go to college and came to the rubber plantation to work. He Quan studied and worked abroad for many years, later inherited the rubber plantation, and also ate with He Jun and He Cheng, but that was it."

Liu Jinghui tutted twice: "Runtu?"

"Hmm?" Zhong Renlong couldn't quite catch this meme.

Liu Jinghui waved his hand: "You said they are related to interests?"

Zhong Renlong nodded and said: "He Jun and He Cheng resold supplies through Green Pine Farm. Green Pine Farm has always had a route for reselling supplies. However, they haven't admitted to killing anyone yet, and we are preparing to take them back for careful interrogation."

"Can they explain the situation of reselling supplies clearly?" Liu Jinghui didn't follow Zhong Renlong's train of thought.

"They confessed some, but didn't explain it very clearly."

Liu Jinghui looked at Jiang Yuan.

Jiang Yuan nodded lightly: "It's indeed impossible for the sake of interests."

Killing for interests and becoming a serial killer is too much of a loss.

The cost of killing in modern society is still quite high. In ancient society, there could be a black shop like the one in Water Margin that lived by making human meat buns and taking guests' luggage. In modern times, those who are really determined to kill can obtain benefits far exceeding "reselling supplies." The interest chain of serial killing is estimated to require drug-trafficking-level income to support.

On the other hand, the killing mode of a serial killer and the choice of killing targets are also different from ordinary interest-based killing.

In fact, if killing and who to kill were decided solely by interests, this case might have been solved long ago.

Zhong Renlong also understood the truth of this, but Jiang Yuan's "pointing out" obviously carried different weight. Zhong Renlong immediately became serious and asked: "Is the killer someone else?"

"Judging from the black-faced manager's corpse, the killer might not be one person." Jiang Yuan gave a bold guess.

Zhong Renlong widened his eyes: "Do you mean the manager wasn't killed by the serial killer?"

"I think we can deal with it separately for now." Jiang Yuan didn't give such a definite answer, and his statement could also give Niza and Zhong Renlong some room for buffer.

If it were directly announced that these were murders with different targets by different suspects, Niza and the others would have worries, and considering the subsequent court proceedings, it would be difficult to choose.

Now there is no need to choose; just catch more people.

Zhong Renlong looked at Jiang Yuan nervously: "Then who do you think is the killer of the serial murder case?"

"Zhang Fan." Jiang Yuan actually gave him an answer.

Zhong Renlong didn't align the person for a moment.

Jiang Yuan said: "Among the four suspects, Li Wanzhong is dead. Judging by the method of death, it doesn't look like a serial killer's work. The two people surnamed He were just ruled out, so that leaves the last suspect, Zhang Fan."

Zhong Renlong hesitated for two seconds: "I remember now, but as for this Zhang Fan, it seems there is no other suspicion."

"He is the only person in the He family rubber plantation who had the opportunity to commit the crime. If it's not him, we have to consider personnel outside the plantation." Jiang Yuan didn't bite to death either; specifically what happens depends on subsequent evidence.
