Han Lingling inquired about the residence of Chen Jialu's family in the communication room, Chen Jialu's father's name was Chen Shouzhi, and he was the director of a certain department of the Jingnan Military Region before he retired.

Chen Jialu's parents confirmed that this afternoon, Duan Dawei did help his family repair the TV. The time for Duan Dawei to Chen Jialu's house is about 4:05 (it does take more than ten minutes to get from Duan Dawei's house to Chen Jialu's house), and the time to leave Chen Jialu's house is around 5 o'clock.

Chen Jialu's parents like Duan Dawei very much, including the neighbors who visited Chen Jialu's house have a very high evaluation of Chen Jialu, Chen Jialu is very sincere, and he is also very enthusiastic about treating people, he helps people repair electrical appliances, rarely collects money, and really can't refuse, so he charges a little less, which is much cheaper than the charge of electrical repair shops. Judging from this, it is not surprising that Duan Dawei often helps Mr. Ma's family to do things.

Duan Dawei is not the murderer of Mr. Ma's family of three. Now there is only the nameless Gui classmate left.

Ouyang Ping must investigate Gui and follow the procedure, which is necessary, but Ouyang Ping does not have much hope for this Gui classmate. Between four and five o'clock, which is the busiest time for banks, people working at the counter can't leave the counter.

The next morning, at about eight o'clock, Ouyang Ping and his entourage went to the Industrial and Commercial Bank of Qili Street, Rehe Road.

The bank opened at half past eight o'clock, and around eight o'clock, the staff of the bank had already begun to make preparations for the opening of the door.

After listening to Ouyang Ping's explanation, the lobby manager invited the salesmen of counter No. 1 and counter No. 4 to an office on the second floor.

The three of them already knew the intention of Ouyang Ping and his entourage, and last night, Jingnan TV had already reported the homicide that occurred in the Jingyuan community on the small street.

The lobby manager confirmed that at two o'clock in the afternoon on the 11th, Mr. Ma did go to their business office to withdraw 260,000 yuan, and this matter was arranged by the lobby manager, because the amount is very large, according to their usual work experience, as long as it is a large amount of business, they all operate in this way, and there is no problem of special care.

As for Gui, his name is Gui Qingguan, on the afternoon of the 11th, Gui Qingguan saw Mr. Ma queuing outside the No. 1 counter, so he said hello to Mr. Ma, and when he learned that Mr. Ma was going to withdraw tens of thousands of yuan, he handed Mr. Ma to the lobby manager. Teacher Ma was very cautious, and when he spoke to Gui Qingguan, his voice was very low. He only said that he mentioned tens of thousands of yuan, but we didn't expect him to mention 260,000 yuan. In the sales department, there are very few customers who withdraw such large amounts of cash.

The lobby manager said that this afternoon, there were a lot of people in the business hall, and the 11th was the day to get paid, and everyone lined up outside the business hall. All the salespeople were so busy all day that they couldn't leave the counter at all.

The salesperson at counter 1 and counter 4 also confirmed the lobby manager's statement. Yesterday, because there were too many people in the business hall, the number of times they went to the toilet was reduced a lot. Throughout the day, Gui Qingguan never left the counter for half a step, and even ate lunch at the counter.

Finally, the lobby manager invited Gui Qingguan to the office.

As Mr. Ma said, Gui Qingguan's height is about 1.80 meters, thin, and there is a black mole on the arch of the eyebrow of his right eye.

Obviously, Gui Qingguan's suspicion has been completely ruled out.

Now that Gui Qingguan's suspicion has been ruled out, why did Ouyang Ping still look for him?
