"Qianqian, you accompany Brother Xiong to chat, I'll go out and rescue it!" Ning Mingyue rolled her eyes, said a word to the two, and left quickly.

Su Ziqian: ......

Put her and the suspect in the same room, is this a real sister?

But fortunately, Ning Mingyue did come back soon as she said, but when she came back, she was still carrying a black schoolbag on her back.

"Little girls, is the interview over?" Xiong Daquan scratched his head a little irritably, and when he saw Ning Mingyue coming, he hurriedly asked.

Ning Mingyue smiled slightly and said, "I'm very happy, but before it ends, I'm going to trouble Brother Xiong, I want to see the elevator machine room!" ”

Xiong Daquan shook his head with some embarrassment: "Little girl, these things can't be seen by outsiders." ”

Ning Mingyue hurriedly took out the wine in her backpack that she had just bought in the small shop outside, quietly handed it to Xiong Daquan, and then said pitifully: "Brother Xiong, just let me take a look, I definitely won't tell others, you said that this case is so strange, I really can't sleep if I don't find out!" Besides, Brother Xiong, don't you want to know what's going on in this case? ”

Xiong Daquan looked at the Moutai wine in his hand, and then thought that he was also tortured by the tragic appearance of the dead every day, and besides, the people in the police station had finished investigating, so what did it matter if one person took a look.

Ning Mingyue saw that Xiong Daquan was a little moved, and hurriedly added a fire: "Brother Xiong, you see that if the police investigate, you will definitely be easily included in the suspect, only if we find evidence in our favor first, can we not be passive, right?" ”

Xiong Daquan thought of the incident that was interrogated by the police yesterday after Su Weiwan and the others left, nodded with some trepidation, and then gritted his teeth and said, "Sister! Brother believes you today, you must come up with something useful, don't live up to my brother's trust in you! ”

"Don't worry, Brother Xiong!"

Su Ziqian: ......

She felt that she had no need to speak, her sister was so powerful, she felt that she was no different from the oil bottle......

The two sisters followed Xiong Daquan to the elevator switchboard on the first floor, she stepped forward and began to carefully investigate each part with a flashlight, and at the same time chatted with Xiong Daquan about the movements of the rest of the personnel on duty on the day of the crime.

"Brother Xiong, there are officers on duty on every floor, did you see anything suspicious in the surveillance video that day?"

"Personnel on each floor are generally not allowed to go to other floors during working hours, and the police have seen the surveillance footage, and no one has any suspicious actions."

Ning Mingyue sighed a little disappointed, then seemed to think of something, and then spoke: "What about the rest?" What cleaning staff, plumbers and the like? ”

Xiong Daquan replied angrily: "There shouldn't be, everyone has been interrogated by the police, but then they were all released, there should be no problem." ”

Ning Mingyue didn't ask any more questions, she used a flashlight to carefully inspect the various organs under the general control.

If the elevator is divided according to the structure, there are several parts of the machine room, the shaft, the pit and the floor. The important control organ is in the computer room, and when Su Weiwan inspected the computer room again, he focused on checking whether there were timer devices under the main gate for heavy objects to pull.

If the murderer pressed the alarm of the elevator on the tenth floor, and then quickly came to the control room on the first floor to speed down the elevator, then he would definitely meet Xiong Daquan on the way, but Xiong Daquan didn't need to meet this person at all yesterday.
