The interrogation of the four security guards began intensely again. They were still interrogated in isolation, with the same interrogators and suspects as last time, but this time the questions asked were the same topic: fire extinguishers!
In order to make the description more convenient, and to allow everyone to fully understand the mental state of the four security guards, we have compiled their answers to each question raised by the police below.
The police asked: What is the fire extinguisher in the east security room used for?
Wang Hu said he didn't know, he didn't notice there was a fire extinguisher there, and he didn't usually go to that place.
Li Qiang and Zhang Jie said it was probably used to put out fires.
Ren Zhong replied: It was purchased by the project department. The Emergency Bureau required the construction site to be well equipped with fire extinguishing equipment, so I bought it and stored it there. It will be placed on the construction site after the construction starts.
The police asked: When did the fire extinguisher arrive?
Zhang Jie and Li Qiang said it seemed to have been four or five days.
Ren Zhong said it was delivered on the 3rd.
The police asked: Who arranged to put it in the east gate security room?
Zhang Jie and Li Qiang said it was arranged by the captain.
Ren Zhong said that he was off work when the goods arrived that day. Someone from the project department called me and asked me to help collect them. I thought that the security room at the east gate was empty anyway, so I arranged to put them there.
The police asked: Who was involved in unloading the car?
Li Qiang and Zhang Jie said that we and the delivery driver unloaded the goods together.
Ren Zhong said it was Zhang Jie and Li Qiang.
The police asked: Did that box come with the fire extinguisher?
Li Qiang and Zhang Jie said yes. Since the box was too heavy for us to move, we first carried the fire extinguisher in, then carried the empty box in, and then put the fire extinguisher in.
The police asked: Who determined the location of the boxes?
Zhang Jie and Li Qiang said they were captains.
Ren Zhong said I asked them to put them against the wall so they wouldn't get in the way.
The police asked: Where did you put the box?
Zhang Jie said it was placed against the wall.
Li Qiang said that the driver wanted to put it at the door, but I was afraid of being scolded by the captain, so he pushed the box inside against the wall.
The police asked: Did anyone touch the fire extinguisher after it was put away?
Zhang Jie and Li Qiang said they didn't know.
Ren Zhong said that Engineer Wang from the project department should have checked and accepted it, but he didn't know whether it had been touched or not.
The policeman asked: Is the door to the east guard room always locked?
Ren Zhong said that because the east gate is temporarily closed, the door is locked and the key is hung on the wall of the west gate security room.
After asking the four security guards about their relationship with these fire extinguishers, the police were unable to determine who was the internal agent for the time being. Each of their answers was reasonable and flawless. In the interrogation control room, Liang Shi and Bian Xingxue formed a circle.
Standing, discussing what to do next.
"It's not an option to continue like this. We really can't find any basis for them to lie." Tang Feng said a little discouraged.
"If that doesn't work, increase the intensity of the interrogation, work in shifts, and endure them." Bian Xingxue said.
Liang Shi waved his hand, shook his head, turned around and picked up the cigarette box on the table, but there was no cigarette left in the box. He flattened the cigarette box and threw it into the trash can next to him. He stood.
Tang Feng, who was beside him, quickly took out his cigarette and handed it over. Liang Shi lit the cigarette and took a deep breath before saying:
"Take these four people back to identify the scene. First restore the fire extinguisher to its original position and ask the four of them to go in one by one. Judging from the changes in their emotions and expressions, I don't believe that these people can hide it from my old man."
"Copy that." Everyone agreed at the same time and turned around to get ready.
"Ma Yan." Liang Shi called her from behind.
"Captain Liang, do you have any other instructions?"
"Call that Xu Wen, this guy has very vicious eyes."
"yes."
After the technicians completed the investigation of the scene, Bian Xingxue's men restored the wooden box and fire extinguisher to their original appearance, and installed two hidden cameras from two angles in the room to record any possible suspects.
Subtle changes in expressions occurred. In addition, brighter lighting equipment was installed indoors to enable observers to see everything in the room clearly.
After Xu Wen arrived at the scene and had a brief exchange with Liang Shi, he understood Liang Shi's intentions and began to admire Liang Shi, an old detective, from the bottom of his heart. The two of them stood indoors and directly observed the suspect, while Bian Xingxue and others crowded around.
In a van, staring at the camera screen.
The first person brought in was Ren Zhong. In order to achieve a better inspection effect, the police deliberately put handcuffs on each of them. After Ren Zhong entered the room, he looked around and then discovered the wooden box in the corner.
The moment he saw the wooden box, Ren Zhong frowned slightly. Then under the police's order, he walked to the wooden box, opened the lid of the wooden box and took a look.
Ren Zhong's expression was dull during the whole process. Only when he saw the wooden box, his expression changed a little. After seeing Ren Zhong's performance, Liang Shi and Xu Wen looked at each other and shook their heads helplessly.
.
The second person to come in was Li Qiang. After he entered the door, he looked to his left. It seemed that he knew the location of the box. After seeing the box, he hesitated for a moment, then turned to look at Liang Shi, as if he had something to say.
Want to say.
"What's wrong? Is there any problem?" Liang Shi asked.
"This box, it turns out it's not there." Li Qiang pointed at the box with both hands and said.
"Where was it originally?"
Li Qiang took a few steps forward, came to the left side of the box, in the middle of the wall, tapped his foot on the ground and said:
"I remember pushing the box to this position, almost as far away from the south and north walls."
"You mean someone moved the box after you put the fire extinguisher away?" Liang Shi asked.
"Yeah." Li Qiang nodded.
Liang Shi and Xu Wenyou exchanged glances, Xu Wen nodded, and then the police took Li Qiang out.
Zhang Jie was in a similar situation to Li Qiang when he came in. He also said that someone had moved the box.
"It seems that someone did move the box." Liang Shi said.
"Does this eliminate their suspicion?" Xu Wen said.
"According to normal reasoning, this is the case, but if they collude, it may not necessarily be the case."
"Well, let's take a look at the performance of the last person. Maybe there will be more surprising discoveries."
When Wang Hu came in, he made the same movements as Ren Zhong. He first turned his face to the right, and then to the left. The difference from Ren Zhong was that his movements were more exaggerated, with an obvious slow head turning movement, while Ren Zhong
Zhong's movements seemed smoother. Xu Wen also noticed that Wang Hu's forehead was moist. Although there were no beads of sweat, it was not dry either.
Under the police's order, Wang Hu walked to the box, bent down, opened the lid of the box, took a look inside, and then closed the box again.
Liang Shi and Xu Wen watched every detail of Wang Hu's movements, staring at his hands, his feet and his face, capturing the subtle changes in his movements and expressions.
When Wang Hu closed the lid and stood up and took two steps back, Liang Shi and Xu Wen looked at each other at the same time, with a satisfied smile on their lips.
