After the meeting ended, Su Haohu's parents rushed to the detachment, and Brother Song and Xun Mu accompanied them to identify the bodies, and comforted them, promising to solve the case as soon as possible, bring the murderer to justice, and give the victim an explanation.

Early the next morning, Brother Song volunteered to take Qi Yuan to Qihua County to investigate the pesticide factory under Xiong Yunqi's name.

And Xiong Yunqi was also present, just in the car.

Along the way, Brother Song has been quietly looking at Xiong Yunqi, the reason why she was pulled up is actually a stress test, if she has a ghost in her heart, in the process of pulling her step by step to explore the truth, she will inevitably be nervous and anxious, and Brother Song can also have a more accurate judgment on this.

However, she never behaved unusually, but fell asleep leaning against the car door.

In this way, she either has a clear conscience or has a strong psychological quality.

From Yuqiao city to the suburbs of Qihua County, it is still quite far, more than 100 kilometers, and it takes about an hour and a half to drive.

What's more, they have to go to the county seat to go through the formalities first.

By the time I got to the pesticide factory, it was already past eleven o'clock.

Fortunately, this investigation is a surprise inspection, not only with Xiong Yunqi's cooperation, but also Xiong Yunqi promised not to greet the factory, Qi Yuan stared at it along the way, and indeed did not find her ventilating the news, but it avoided the risk of someone ventilating the message so that people with intentions could prepare early.

From this point of view, Xiong Yunqi is indeed frank.

Hearing that the police came to investigate, Xiong Yunqi's sister was still a little surprised, and hurriedly ran down, accompanied by a smiling face, and after learning that the Song brothers were coming, they asked people to hurry up to prepare a record list, and on the other hand, they took the opportunity to pull Xiong Yunqi aside and asked what was going on.

Xiong Yunqi found that Qi Yuan was paying attention to herself, so she smiled slightly, shook her head and said, "Don't worry, sister, it's not a big deal, let's just cooperate with the investigation, not to embarrass us." ”

"That's good, that's good." Her sister breathed a sigh of relief.

Xiong Yunqi said again: "Sister, you go and go about your own business, just leave it to me here, and I will take two police officers to investigate." Rest assured, it's really fine. ”

Her sister was skeptical, but when she saw that she was resolute, she also nodded, left, and informed the workers in the factory to do their own thing, leaving only the person in charge of warehouse management to cooperate with Brother Song's investigation.

Soon, Brother Song found a problem, handed a list to Xiong Yunqi, and asked, "There is a problem with this list, the high-concentration thallium sulfate used to make rodenticides is a full five hundred grams less." ”

"What?" Xiong Yunqi was taken aback, and quickly took the list over for comparison, and after looking at it a few times, the cold sweat immediately came down, and asked anxiously: "Ah He, what's the matter?" Why is thallium sulfate missing a pound? ”

With the toxicity of thallium sulfate, 500 grams is enough to poison thousands of people, and if you concentrate on poisoning, you can poison hundreds of people, which is very terrible.

After Brother Song learned that the amount of theft of this thing had reached 500 grams, he was also taken aback, and after questioning Xiong Yunqi, he quickly took out his mobile phone and reported the matter to Su Ping.

"Five hundred grams? You're not mistaken, right? Su Ping was taken aback, and a roar came out of the mobile phone receiver clearly: "Hurry up!" Notify local colleagues to quickly file a case for investigation, and immediately set up a task force to find out where this batch of thallium sulfate has fallen and in whose hands, quickly! ”

"Yes!"

"I will immediately notify the city bureau and jointly investigate with local colleagues. In short, it is important to catch the murderer as quickly as possible to avoid this batch of poisonous flows out, and not to give him a chance to commit the crime again! ”

"Understood!" Brother Song hung up the phone, looked at Xiong Yunqi, and made a call again.

"Hello? Hello, is it the Huzhou Public Security Bureau? Well, I am the leader of the Serious Crime Brigade directly under the Yuqiao City Public Security Criminal Investigation Detachment, Zhao Qingsong, the police number is 050XXX, and now because of a poisoning case, I am on an investigation mission in Qihua County......"

After quickly explaining the antecedents, he immediately said: "Now I am in the Qihua County Xiaoxiong Pesticide Factory, I found that the warehouse has lost 500 grams of thallium sulfate processed by the factory to process rodenticides, and now the whereabouts are unknown, please pay attention to it, immediately set up a special team to investigate, find the whereabouts of the batch of thallium sulfate, and my Yuqiao Public Security Criminal Investigation Detachment will fully cooperate!" ”

"Hello, I have learned the specific situation, and I will repeat it now," the other party said: "In the Xiaoxiong Pesticide Factory in Qihua County, 500 grams of thallium sulfate, a highly toxic substance, were stolen, right?" ”

"I'm not sure if it was stolen, but this batch of thallium sulfate is not in the factory."

"Understood, thank you for the information, I will immediately report to the city bureau and notify the criminal investigation detachment, and a colleague will contact you later, please keep the phone open."

"I know, I'm just waiting in the pesticide factory."

Hanging up the phone and putting away the phone, he looked at Xiong Yunqi and asked, "How is it, can you find out?" ”

Xiong Yunqi gritted his teeth and said, "Specifically, the stolen thallium sulfate is not five hundred grams, but six hundred and seventeen grams...... Officer Zhao, I don't know what's going on, so let's fully cooperate with your investigation and find this batch of thallium sulfate first, what do you think? ”

"Hmm." Brother Song nodded lightly and said, "Prepare the surveillance video and employee roster in your factory, and besides, who is in charge of this?" Call here, I want to know who has entered the factory in the near future. ”

"I'll do it." Xiong Yunqi didn't say anything, and hurriedly called her sister to inform her.

At the same time, Brother Song said to Qi Yuan again: "Xiao Qi, you call the Su team again to ask about the situation, and tell the Su team about it, I suggest that Su Kaiyong and Cao De be closely monitored immediately, and if allowed, they will be searched as soon as possible." ”

"Okay." Qi Yuan knew that the stakes were high, and immediately took out his mobile phone. After thinking about it, he handed the phone to Brother Song and said, "Brother Song, why don't you call?" ”

"Okay." Brother Song's jaw. His mobile phone has to be kept unblocked, so he asked Qi Yuan to do this, since Qi Yuan is afraid that he can't say it clearly, then it is the same with Qi Yuan's mobile phone.

After finishing speaking, he hung up the phone, his own mobile phone rang again, it was an unfamiliar number, he guessed that it was a call from the Huzhou City Public Security Criminal Investigation Detachment, and when he got through, he found that it was indeed the case.

The lost thallium sulfate stirred up the nerves of all parties, and all the units concerned quickly moved and burst out with extremely high efficiency.

After a while, the Qihua County Criminal Investigation Brigade felt the scene first, directly semi-blocked the pesticide factory, and pulled the employees to interrogate one by one.

When Brother Song saw it, he frowned slightly, it was not in compliance to forcibly detain employees without evidence, but he mentioned it, but it was not accepted by the captain, so he had to give up.

At the same time, several map detectives also took the surveillance video and watched it carefully at the scene. Brother Song and Qi Yuan couldn't help much, so they walked behind the map detective police and watched the video together.

"Su Kaiyong?" Soon, Brother Song found an acquaintance and immediately shouted a pause: "He is one of the suspects in the poisoning case!" ”
