In the evening, Brother Song answered another phone call and learned a series of news.

Lao Hai they have gone to Dahu County to verify, the afternoon before yesterday, Su Kaiyong did sell a lot of pesticides, with the cooperation of the local police station, door-to-door visits, all these pesticides were recovered, of course, they were compensated, and the purchase arrears were returned, Su Ping did not let them do anything that harmed the interests of the people.

A total of 217 bottles of pesticides were recovered, and 93 grams of pesticides were extracted after rapid distillation, plus the previous 404 grams, there is still a gap of 3 grams, which has always been an unavoidable loss when filling preparations.

In addition, under the pressure of interrogation, Su Kaiyong also confessed to the woman he was looking for, and she was also brought back to the detachment for interrogation, verifying Su Kaiyong's confession.

This woman has an average background, but her figure is okay, and she is also very good at makeup and dressing, according to Su Kaiyong, her craftsmanship and ventriloquism are very good, so the price is not low, three thousand one nights.

"Brother Song," after getting this information from Brother Song, Qi Yuan immediately said: "I don't think Su Kaiyong is the murderer, just like Team Xun said, if he had premeditated and wanted to commit the crime, then, no matter what, he should not refuse Su Haohu's initiative to lend him another sum of money to contract the express outlet."

If he had a weak heart, or if his conscience was still clear and he couldn't bear to care about Su Haohu borrowing money, then he would not have committed such a thing as poisoning and killing, and he would stop the precipice in time. ”

"But you ignore one point," Brother Song shook his head lightly, and said: "Don't forget, the so-called 'lend him another sum of money' was also said by Su Kaiyong himself, and no one else can prove that the only party in the words except him, Su Haohu, is dead, and there is no proof of death." ”

Qi Yuan was a little stunned.

"Think about it, is there such a possibility, Su Haohu was worried that the matter would be revealed, so he came up with such a story.

Starting from the possible motive for committing the crime, the logic is actually very simple, if it is really him who committed the crime, the motive is most likely economic reasons, and he doesn't want to repay such a large amount of money.

Since the motive is money, the simplest and most direct way to rule out the suspicion of committing the crime is undoubtedly to start from the money and make the motive for the crime untenable.

If you think about it, this is not a low probability. No matter how generous Su Haohu is, there is no reason to take the initiative to propose to a person who owes him hundreds of thousands, and then lend him hundreds of thousands to open an express outlet, right?

Even if this person is his own uncle, it is unlikely, after all, his own money is not enough to be squandered like this, and hundreds of thousands are not a small amount for him.

Coupled with Su Kaiyong's experience of several failed investments, even if Su Kaiyong came up with a project that sounded very safe to find him, he would probably have to mumble and hesitate for a long time, and the probability of hesitation is not whether to borrow money or not, but how to prevaricate without offending people as much as possible. ”

Qi Yuan opened his mouth, but found that he had nothing to say.

"Of course, this is just my subjective speculation, we don't know Su Haohu as a person, so we can't judge his thoughts. Maybe he saw Su Kaiyong repay it like this, he couldn't pay off the money in his life, and it was annoying to repay the loan and repay it, so it was not impossible for him to take the initiative to find an effective plan for Su Kaiyong to do it.

Moreover, judging from what I have heard so far, Su Kaiyong's performance in the face of interrogation, I actually don't think he has the brains to start from the motive and make up such a story that can significantly reduce his suspicion.

If he has this mind, and in addition to the stinky problem of prostitution, running a business can be regarded as diligent and hardworking, and he should not be down to this extent. ”

"Then ......" Qi Yuan was confused: "Brother Song, do you think it was Su Kaiyong's poisonous criminal?" ”

"What do you say?" Brother Song said: "The three suspects, Xiong Yunqi, Su Kaiyong and Cao De, have only found that Su Kaiyong stole thallium sulfate. ”

Qi Yuan was silent again and stopped talking.

"So, now the focus is on Xiong Yunqi." Seeing this, Brother Song said again: "Xiong Yunqi, there are also conditions to get thallium sulfate. If a colleague from the Graphic Investigation Department ruled out her suspicion, then the murderer would be Su Kaiyong. And if it can't be ruled out, it will have to be checked again. ”

As soon as the words fell, I saw the captain of the Qi Hua Criminal Investigation Brigade striding over.

"What's wrong? Did you find anything? Brother Song saw it and hurriedly asked.

"I didn't find any problems, only a list of people who had entered and exited the warehouse, as well as information such as the number of times and time." He handed out a list and said, "It's all here, so let's see, I'll take the brothers to dinner first." ”

"Thank you, thank you for your hard work."

"It's nothing, it's a matter of duty."

Seeing him leave, Brother Song picked up the list and looked at it carefully.

Soon saw a name, he said: "The surveillance captured that Xiong Yunqi entered the warehouse eight days ago. ”

"But as one of the owners of this pesticide factory, it is normal for her to go in and out of her warehouse, so it doesn't mean anything, right?" Qi Yuan glanced at Xiong Yunqi, who was sitting on the steps eating a boxed lunch.

"yes, that's normal." Brother Song sighed: "There is no direct evidence, it's troublesome." ”

"Are there two possibilities now?" Qi Yuan asked again.

"Tell me about it."

"First, Xiong Yunqi had seen a copy of thallium sulfate in advance, but she was worried that after the incident, the police would soon be able to track her down through the important clue of thallium sulfate, after all, even if this factory did not apply for a review of thallium sulfate production qualifications again, the control was still very strict, and it was easy to find that thallium sulfate was less than 100 grams.

So she hesitated and didn't do it until the day before yesterday when she found that there were 500 grams of thallium sulfate missing, and she felt that she had seized the opportunity to do it immediately yesterday afternoon.

The second possibility is that this matter has nothing to do with Xiong Yunqi, Su Kaiyong did it. ”

"Which one do you think is more likely?" Brother Song asked again.

"It's all possible." Qi Yuan said, then lowered his head and pondered for a while, sighed, and added: "Relatively speaking, the second possibility is more likely. ”

"Basis?"

"What a coincidence." Qi Yuan said: "With such strict control of thallium sulfate, six hundred grams of thallium sulfate have been stolen over the years, there is no reason why Xiong Yunqi just stole it with his front foot, and Su Kaiyong took it with his back foot."

And except for Xiong Yunqi's visit eight days ago, he has been staying in Yuqiao these days, and it is impossible to know that another 500 grams of thallium sulfate were stolen from the warehouse.

Of course, it cannot be ruled out that she doesn't know at all, but she is simply unbearable and determined to take risks, but this is even more coincidental.

Team Xun said that something sounds very coincidental, but there is likely to be a problem, and the possibility of a simple coincidence is very low. And there are too many coincidences in this hypothesis, so it is likely that the hypothesis is not true. ”

"Make a call and report the news." Brother Song handed him a cigarette, but did not say anything, only said: "Let the Xun team and the Su team decide." ”
