According to the clues provided by Qiu Yu, Gao Feng instructed Nie Wanli to arrange for the police to investigate the people who had dinner with Zuo Hui and went to the song hall to see if there was anything suspicious.

Those people were all customers who had business dealings with Zuo Hui, all of them had drunk too much, and some of them couldn't answer the phone at all.

Fortunately, these people stayed in the same hotel and it was easy to find them.

After a simple questioning, the suspicion of these people can basically be ruled out.

At the time of Zuo Hui's accident, all these people were in the song hall and did not leave, they left after the fact.

There is another important detail, that is, when Zuo Hui answered the phone, these people could testify to each other, and no one answered the phone.

The suspicion of these people was ruled out, but for the sake of insurance, Nie Wanli still arranged for people to monitor these people, and they were not allowed to leave the hotel until the case was investigated.

"You said that Zuo Hui lost control of his emotions after answering the phone, how did he behave at that time?"

Gao Feng re-inquired about Qiu Yu, hoping to find useful clues.

"I vaguely heard him muttering the same phrase like 'he's alive' or something.

Before he left, he made another phone call and got into an argument with the other party, yelling 'I saw it with my own eyes'. ”

Qiu Yu reminisced and preached.

"Why didn't you say it earlier?"

Gao Feng said with a little complaint, turned his head and commanded Nie Wanli,

"Immediately let people block the song hall where Zuo Hui went, and let people investigate all the surveillance videos."

"You shouldn't be suspicious ......"

Gao Feng didn't wait for Nie Wanli to finish speaking before speaking: "That's right, that person appeared in the song hall, otherwise Qiu Yu wouldn't have said the sentence 'I saw it with my own eyes'." ”

Nie Wanli immediately did as Gao Feng instructed.

Qiu Yu asked with some confusion: "Who is the person you suspect, why are you sure that he is in the song hall?" ”

"It's simple. Zuo Hui behaved very normally during the meal and on the way to the song hall, which was abnormal only after he received the phone in the song hall, plus the last sentence he said, it was certain that the other party had appeared in the song hall. ”

Gao Feng explained.

"Who is this man?" Qiu Yu asked.

Gao Feng didn't answer, and asked rhetorically: "Who do you think Zuo Hui called before he left the hotel?" ”

There is no call record on Zuo Hui's mobile phone, unless Qiu Yu lied, otherwise Zuo Hui deleted the record himself after the call.

"I ...... I don't know. Qiu Yu hesitated and shook his head.

"It's for Ding Baixue, right?" Gao Feng asked suddenly.

Qiu Yu's expression was a little unnatural, and finally nodded.

Gao Feng sneered in his heart.

The relationship between Zuo Hui and the secretary Qiu Yu is definitely not as simple as it seems on the surface, but he and Ding Baixue are not clear, which makes Qiu Yu secretly jealous.

"Xiao Yue, give Ding Baixue a call and see what she is doing now." Gao Feng turned around and commanded.

"Oh, good."

Xiao Yue took out her mobile phone and dialed Ding Baixue's number, and after a while, she said,

"No one answered."

"Oops!"

Gao Feng screamed, his face changed suddenly, and he shouted as he ran downstairs,

"Xiao Yue, hurry up and follow me to Ding Baixue's house!"

Seeing this, Nie Wanli shouted: "Gao Feng, you shouldn't be suspicious of Ding Baixue'......"

"Hopefully it's not what I thought it would!"

Gao Feng replied, and shouted again after a slight pause,

"By the way, let's see if there is any monitoring where Zuo Hui had an accident!"
