Is it normal to live on the phone to help your boyfriend investigate the case?

Qu Mingcong said with a smile: "He is an old man, not some 'guy'."

She snorted, "Anyway, I don't like him."

"Well, I don't have a good impression of him either." Qu Mingcong had already walked to the security booth, "But I still have a good impression of the 100 million."

Even if you don't get 100 million, it's not bad to share the bonus with others.

The security pavilion is a small house connected to the outer courtyard wall. In line with the architectural style of the museum, the roof is made of antique cornices and the windows are also designed to be round. However, the interior decoration is still modern, with a complete set of tables, chairs and computers. .

Qu Mingcong stood at the door and glanced at the computer monitor. The monitor screen was divided into several pieces by the monitoring screens of different areas, and different floors of the museum could be seen in real time.

The security guard was a sturdy man around 40 years old. He saw Qu Mingcong at the door and looked him up and down.

"Hi, excuse me." Qu Mingcong showed the security guard the invitation card that Ding Zhaolin sent earlier, "I want to ask a few questions about the case."

"I didn't see you coming here a few days ago," the security guard muttered in a low voice. "Other people have come here to ask questions many times."

Qu Mingcong smiled casually, "I was busy with other things a few days ago, which delayed my time."

"Come in and sit down." The security guard dragged a chair away and motioned for Qu Mingcong to sit down, "I have been working here for four or five years. I happened to be on duty the night Miss Ding had an accident. I remember very clearly that I was holding a flashlight at the time. On patrol, when I walked to the outside of the East Hall, I suddenly heard a bang, as if something had broken... I scanned with a flashlight and found a lot of porcelain fragments on the ground in front of me. I subconsciously looked up to see if it was Where did she fall from, and then I saw Miss Ding standing on the windowsill... In the blink of an eye, she fell headfirst, alas, what a girl, she just died like this."

Maybe it was asked too many times, but before Qu Mingcong could ask, the security guard had already explained the situation clearly and let out a long sigh.

Qu Mingcong asked him, "What was the expression on Ding Na's face at that time?"

"It happened so fast, I didn't have time to watch it," said the security guard, frowning. "And she was standing at such a high position, and it was late at night, so no one knew the expression on her face."

This answer was expected by Qu Mingcong, because if he could see the expression clearly, there would not be so many doubts. From the expression of a person when he fell to his death, he could basically judge whether it was suicide or an accident.

He thought for a while, and then asked the security guard: "It was around 12 o'clock in the night when she had an accident. Why did she stay in the museum so late and didn't go home? Do you know the reason?"

The security guard shook his head, "Almost every time she comes to the museum, she stays until late at night, sometimes all night, everyone is used to it."

"Can a student have so much time?" Qu Mingcong asked in surprise, "Could it be doing homework in a museum?"

He knew that some candidates thought there were too many people in the classroom, so they would go to the study room to study by themselves after school.

The security guard grinned, "What kind of homework do you do? It's fine if you don't skip classes, but I don't think Mr. Ding and Mrs. Ding expect her to go to college, so let her do everything."

Qu Mingcong thought to himself, no wonder Pan Fang felt that Ding Na was so obsessed with antiques that she became obsessed. She was only [-] or [-] years old, and she didn't go shopping or watch movies. She spent every day in museums and didn't even care about her studies. She was indeed "crazy" .

"By the way, I met Pan Fang on the road just now. He said that he found out from you that Ding Na didn't go to school for a while before the college entrance examination and stayed in the museum. Is this true?" Qu Mingcong asked.

"Does this have something to do with her jumping off the building?" The security guard looked puzzled, "There are access controls on the third floor of the east building, and you need to swipe your card to get in. When we leave the shift, we will check the access control records for the day. I can see Miss Ding's access control records every day, and I also heard Xiao Zhao and the others talking about whether Miss Ding gave up the exam completely, or why she didn't go to school for a few days, so I was deeply impressed."

"Do you still have access control records?" Qu Mingcong asked him.

Compared with information full of subjective consciousness, Qu Mingcong prefers the objective fact of access control records.

"Yes, the records of the last three years are kept." The security guard raised his hand to hold the mouse, and operated on the computer a few times, "We only keep the surveillance video of the last three months, but the surveillance video of the night when Ms. Ding had an accident, because It has been transferred by the police, so it has been kept extra, if you want to see it, you can find Mr. Ding's assistant, he has it."

"Let me check the access control records first." Qu Mingcong said.

The security guard recalled the access control records and moved sideways, "You can only watch here, you can't copy, and you can't take pictures."

Qu Mingcong nodded, sat down and dragged the mouse, began to look at the access control records, and clicked on the Bluetooth button on the computer.

The time for the college entrance examination was at the beginning of June, and the access control records showed that Dinna had been to the museum for four consecutive days since June [-]st, and the latest check-in records of that day were all after nine o'clock in the evening, which is enough to prove the security guard's words It's true, every time Dinna came to the museum, she would stay very late before going home.

There are some other people's names on the access control record, which should be the staff here.

Qu Mingcong noticed that Ding Zhaolin's name was interspersed in the middle.

On the night of Ding Na's accident, Ding Zhaolin was also in the museum. I don't know if the access control records are consistent...

Thinking of this, Qu Mingcong continued to drag the mouse down, and turned to the access control record page of the night of the accident, and sure enough, he saw Ding Zhaolin's name.

The last access control records of the museum staff that night were all between 6:8 and 12:[-] pm, except for Ding Zhaolin, who was after [-]:[-] pm.

"Mr. Ding was there that night?" Qu Mingcong couldn't help asking.

"Yes," the security guard nodded, "Mr. Ding called the police."

"Does Mr. Ding often stay so late?"

"Not very often..." the security guard frowned and recalled, "but there are always two days in a week when I go home late."

Qu Mingcong asked: "Do you know what Mr. Ding does in the museum?"

The security guard sneered, "It's not my turn to ask about the boss, but I heard the police ask. Mr. Ding said that he was writing in his room, uh... that's the website of the museum. Some articles were written by Mr. Ding himself. He seems to be Still writing some autobiography, I also heard people say that, I don’t know if it’s true.”

Qu Mingcong's eyes returned to the computer screen, and he sighed silently in his heart: No wonder Ding Zhaolin was caught in rumors. According to this access control record, there were only Ding Na and Ding Zhaolin in the entire museum that night. How could there be no dirty water? Splash on him?

At this time, Xiao Qiao whispered through the earphones: "Come and see at night, when the time comes to restore the real scene."

Qu Mingcong was silent for a moment, then turned to look at the security guard: "Who is on duty tonight? I want to come over tonight and conduct a field investigation."
