"So I didn't give up, but focused on studying the footprints obtained on the spot, including the footprints obtained by the electrostatic film sampling method, which are difficult to detect with the naked eye."

"Found her footprints?"

"No, so I gave up." Chai Ningning shook his head and followed the words: "But not long ago, after I caught a glimpse of these footprints again, I made a new discovery. ”

"Oh?"

"The center of gravity, or gait," Chai Ningning said: "I found that one of the footprints is quite fresh and obvious Just said, Su Haohu mops the floor, and the kitchen is no exception, if it is an old footprint, it is difficult to extract it even if it is sampled with electrostatic film, let alone visible to the naked eye."

Of course, because Su Haohu invited people to his house to eat hot pot before his death, there were many people who did not require to change their slippers, and there were also many leather shoes and sneaker footprints in the kitchen, and this group of footprints was covered to a certain extent.

However, there are still a few footprints that are not covered, and they are quite easy to separate, and according to the coverage, you can further roughly judge the time left by this group of suspicious footprints.

The problem with this set of footprints is that their gait is clearly different from the other footprints, with the right foot with the center of gravity on the toe and the foot floating, while the left foot has the center of gravity at the heel and the supporting leg is the left leg. ”

"Left-handed?" Su Ping asked, followed by a quick recall of the situation and clues of the three suspects, and said while recalling: "But among the three suspects, there are no left-handers." No, right-handed and left-footed are also quite common, so you can't be so arbitrary......"

"Su Kaiyong's supporting foot is his left leg. The gait is also a little abnormal, and the right leg habitually just rubs on the ground without force. Chai Ningning said: "I have deliberately called up the monitoring in the detachment and seen his walking gait, and I will not be wrong."

I suspect that he may have injured his right foot, or he may have been injured for a long time, so he has left this walking habit even though he has been in good shape. ”

"Oh?" Su Ping put down the report: "I immediately asked someone to check." ”

"I've asked Xiao Gao and Lao to help me check, and it is estimated that there will be results soon, so wait a while."

"Okay."

Su Ping picked up the report again and read it carefully.

If it can be proved that Su Kaiyong entered the kitchen, then his suspicion of committing the crime has obviously risen sharply, and this evidence itself can also be used as an important breakthrough in solving the case.

After turning it over for a while, Xiao Gao came over, saw that Su Ping was stunned, and quickly said hello, and then said to Chai Ningning: "Sister Chai, I found out, Su Kaiyong suffers from gouty arthritis, the main site of onset is the knee joint and ankle joint of the right leg, the medical history is five years, the frequency of attacks is high, and it is mainly controlled by colchicine tablets. ”

"That's it." The corners of Chai Ningning's mouth raised, and he relaxed a lot, sat back on the office chair, and said: "Because I suffer from ventilation and pain, I instinctively support my left leg and stand on my right foot when I walk.

In severe cases, crutches may also be carried out, and the right leg should be avoided from moving and touching the ground as much as possible. Over time, it affected his walking habits, even when he was not sick, he was used to supporting his left leg and avoiding the force of his right leg. ”

"I'll discuss with Lao Xun!" Su Ping said, and then raised the stack of reports in his hand: "I'll take this stack of reports first." ”

"Take it, it was originally given to you."

……

At eleven o'clock in the evening, Xiong Yunqi was taken back to the detachment, and Brother Song and Qi Yuan briefly interrogated her for the first time.

"You still doubt me." After Xiong Yunqi sat down, the first thing he said was: "That's right, I've been in the warehouse, I've seen Ah Hu, and I've divorced him, so it's normal for you to suspect me." ”

"We admit it, and we're skeptical of you." Brother Song said: "But the execution of a custodial summons against you, or even the possibility of a direct escalation to detention, is not the reason for this."

We don't detain people on the basis of subjective suspicion without evidence, otherwise wouldn't we detain whoever we want?

The reason why you were detained is that the factory you opened is suspected of illegal production and illegal operation, and the evidence is conclusive, and as a legal representative, you need to be responsible for this.

Of course, the detention of you was also approved by the Qihua County Criminal Investigation Brigade, and the reason why I asked you to come here is because you are related to this case, and we need your assistance and cooperation, so we are temporarily ......."

"Hehe," Xiong Yunqi chuckled twice: "It's really leaky...... Okay, I'll cooperate, but how do I need to cooperate? You ask me to answer? ”

"What are you doing in the storeroom?" Brother Song asked: "You are rarely in charge of the pesticide factory, you are a typical hands-off shopkeeper, and you rarely even take care of specific affairs, why did you suddenly think of going into the warehouse to have a look?" ”

"The factory has a new batch of raw materials," Xiong Yunqi explained: "I can't name it, I only know that it is very expensive, it is a synthetic drug, it has a strong effect, but it also decomposes quickly, and it has little pollution to the environment, which is likely to be the mainstream of this insecticidal pesticide in the future."

So my sister bought a batch of goods, planned to apply for approval for production, and selected a few villages for pilot operations. Well, for all new pesticides, we will apply for relevant approvals, otherwise we can't package and can't sell the goods.

As for those products that have expired approvals, they should be negligent, the whole pesticide factory is too busy, there are many things up and down, no one is staring at these approval dates, and basically locks the file cabinet when they get the documents.

Shouldn't you give a reminder when this kind of thing is about to expire and let us go through the renewal procedures? We have been producing and operating so well, without warning or stopping. ”

"Forgot the approval date?" Brother Song frowned, this was obviously an excuse, but he didn't want to dwell too much on this, so he said: "In terms of the date, the Qihua County Public Security is responsible, and it is not under our control." Let's get down to business, you're going to check the new batch of drugs? ”

"Well," Xiong Yunqi pursed her lips and said, "We have imported two tons of raw materials, and it is expected to produce 40,000 bottles of insecticide for initial pilot operation and market response, which is enough."

Raw materials per ton of 140,000, two tons of a total of 280,000, is quite expensive, counting other costs, the cost price of each bottle of pesticide has to be close to ten yuan, I'm afraid no household can afford it, easy to lose, I don't recommend my sister to try.

But since my sister was moved, it was not so easy to give up, she said that if this drug really has a strong response, we should seize the opportunity to play the brand effect, even if we lose money and make money in the early stage, we have to do it, and I agreed.

However, firstly, I am really curious about this drug, and secondly, the raw materials are expensive, and I have not signed a long-term supply agreement with the supplier, so as the person in charge and representative of the company, I will go to the warehouse to be responsible for the inspection, no problem, right? ”

"It's reasonable, but can we prove anything other than serious?"

"My sister's office has a letter of intent and a procurement contract." Xiong Yunqi replied, and then asked, "Can you give me a cigarette?" A little tired. ”
