"Pull the CCTV forward for a little while, and I'm going to see when the takeout and drinks on his table were bought." I said to Ouyang Qian. She quickly shifted the timing of the surveillance footage forward.

The actions of the characters on the video screen began to play backwards, and the screen also sped up.

"Stop here." I said to Ouyang Qian.

When we adjusted the video forward to this point, the takeaway and Coke on the computer table in front of Jian Honghong had not appeared for the time being. That is, now he has not been exposed to drinks and food.

"Quadruple as normal."

The picture began to play normally, and the deceased in the picture was still playing the game with relish, and after a while, a person similar to a food delivery person delivered a bag to Jian Honghong, he lowered his head as if to say something to Jian Honghong, and then left.

Jian Honghong quickly opened this pocket, which contained the takeout and drinks he was about to eat!

I asked Ouyang Qian to pull the video back to the scene where the person walked in just now, and then asked her to pause until she could clearly see the face of the person who came.

"What do you think of this person?" I pointed to the face and said that I wanted to ask for the opinion of my comrades.

Ouyang Qian hurriedly said: "This person has a great chance of being a suspect!" He personally delivered takeaways and drinks containing poison to the hands of the dead! We just need to find out who delivered this takeaway! ”

Another young policeman raised his hand, pointing to the man on the big screen and saying, "This person is not wearing the clothes of the food delivery company, he should not be the person who actually delivers the food." I suspect that the delivery guy probably gave the takeaway to this person, who then passed it on to the deceased. ”

I nodded approvingly, acknowledging his answer. Then I spoke to the people who were sitting in the task force.

"First of all, the investigation was around 5:24, where was the store of the merchant who delivered the takeaway, who was responsible for escorting the takeaway, and whether he had passed it on to someone else. Second, investigate the deceased's social relationships, especially his relationship with the man named Hou Yong. This person is very suspicious. Meeting. ”

In this way, everyone went their separate ways, each with their own tasks. Ouyang Qian and I are in a group, and we are responsible for investigating Hou Yong.

There was some news from the medical examiner.

Xiao Zhang from the forensic office said to me: "Team Shao, after our examination, we found that the takeaway that the deceased had eaten was a potato and beef rice bowl with a bottle of Coca-Cola. We found an excess of nitrite in the rice, but nothing in the drink. ”

I nodded and said, "In that case, there should be no doubt that someone deliberately poisoned the deceased, right?" ”

"That's right. Although we can't easily rule out the possibility that the store is mixing salt and nitrite, although this is almost impossible to happen. After all, except for the construction sites and hospital laboratories, where such salt is used, the use of nitrite in other places is strictly regulated. Xiao Zhang said.

In this case, it is likely that the murderer was also a person on the construction site, a person who had access to a large amount of industrial salt, and probably had a grudge against the deceased, so he wanted to kill people in this way.

Then the person Hou Yong mentioned by the proprietress is indeed very suspicious.

I found this man in the local demographic database, and his family lives in a neighborhood not far from the hive Internet café. Soon I got into the car with Ouyang Qian.

After a while, we came to the door of the community, found the property, and inquired about the floor where Hou Yong lived.

We quickly found Hou Yong's home, but after knocking on the door, it was not Hou Yong who opened the door for us.

It's a woman.

"Hello, is this Hou Yong's home?" Ouyang Qian asked.

The woman was still very young, probably in her twenties, and when she saw us looking at the police uniform, her expression was obviously a little panicked, thinking that something had happened at home.

"Well, comrade policeman, do you have anything to do?" She held the door with both hands, looking nervous.

"That's right, we're investigating a homicide case, and this case may have something to do with Hou Yong. Are you Hou Yong's family or ......? "I went up and showed my police sign.

The woman looked at us suspiciously, but when she heard that she was only looking for Hou Yong, her nervous expression relaxed significantly. She first invited us into the house and then sat us down on the couch.

"Would you like something to drink?" She asked shyly.

"No, time is pressing, let's get straight to the point." Ouyang Qian took out a notebook and a pen from her bag, and then began to ask the woman some questions.

"What do you call it?"

"Oh, I almost forgot, my name is Hou Li, and I am Hou Yong's sister."

I saw that Ouyang Qian's writing pen trembled visibly, and then continued to ask.

While they were talking, I stood up and quietly observed the environment in their home. Although this Hou Yong has a good time with people like Jian Honghong, his family doesn't look like a person working on the construction site at all, and he shouldn't be a person like his co-worker.

The house is 100 square meters in size, with smooth marble tiles on the floor, a color TV, and a refrigerator. This family should be considered relatively wealthy.

"May I ask Hou Yong, eh, that is, your brother, what do you usually do?"

"My brother is the owner of a company. I'm a college student, and I've just graduated here, when my brother took me to his home and asked me to work in his company. I'm doing some light work in his company now, and my life is relatively comfortable. ”

"My brother is going to buy me a house in a short time, and then let me find a good husband, and I won't have to worry about it in the future, haha." Hou Li's face showed a happy look.

I went to the door of the living room, made an inward motion to Hou Li on the sofa, and pointed to the rooms inside, indicating that I wanted to go into those rooms to have a look.

Hou Li nodded at me, and then continued to answer Ouyang Qian's question.

This should be Hou Li's bedroom...... Well, this is the toilet, and this is Hou Yong's room...... I opened and looked at every room, but there was nothing special about it.

Finally, I stopped in the kitchen of their house.

The kitchen is very white, the pots and pans are also washed clean, and it looks very comfortable. But this kitchen seems a little too full, which is strange.
