"Duan Dawei, do you know about Mr. Ma's advance to the bank?"

"I know, when I was repairing the electric lights at Mr. Ma's house, Mr. Ma and his wife mentioned the matter of withdrawing money."

The four of them felt at the same time that when Duan Dawei spoke, he was calm and calm.

"How much money to take, do you know?"

"I don't know, judging from what you said, Mr. Ma's case seems to be related to money."

So far, the police have not mentioned the matter of 260,000 yuan - isn't it afraid of irritating Mr. Ma? If Duan Dawei had nothing to do with this case, he really didn't know how much money Mr. Ma had withdrawn from the bank.

Ouyang Ping had a new idea: since Duan Dawei was so familiar with Master Ma's family, he might be able to provide some new clues.

Duan Dawei and Ouyang Ping thought about it together: "Teacher Liu is a big mouth, it is very likely that she inadvertently revealed the matter of money to someone - no matter what is going on in the family, he will shout everywhere, for fear that people will not know - such a thing as money, she will definitely say it, unfortunately Teacher Liu has been killed." ”

"You often go to Teacher Ma's house, apart from you, who are the people who usually appear at Teacher Ma's house? Especially a day or two before the incident. ”

"When Mr. Ma's family has something to do, I will go to Mr. Ma's house, usually, I rarely go, sometimes when I meet Mr. Ma to change the gas, I help Mr. Ma move the gas upstairs, but I never enter the door."

"Why is that?"

"Teacher Liu is a very clean person, if I enter the door, after leaving, she will mop the floor, so if I don't have to enter the door, I won't enter the door. Coincidentally, I didn't go to Mr. Ma's house for more than two months, except for yesterday when I went to Mr. Ma's house to repair the lights and bathroom ceiling. Therefore, before the incident, only Teacher Liu himself knew who had been to Teacher Ma - and the two children might also know. The murderer killed three people in a row - there must be something strange about this. ”

Duan Dawei is right, I'm afraid only Teacher Liu knows, of course, the Chen Qiming sisters may also know, Ouyang Ping vaguely felt that the reason why the murderer poisoned the two children was not only because the two children inadvertently bumped into the accident, but also because he wanted to kill people. It is likely that the Chen Qiming sisters knew the murderer. Therefore, the murderer must kill the Chen Qiming sisters. Judging from the time of the death of the three people, there is a relatively long gap between Mr. Liu and Chen Qiming, after killing Mr. Liu, if the murderer wants to get out, there should be time, common sense tells us that the Chen Qiming sisters should go home together, even if they go home at the wrong time, the interval will not be very long, and the murderer is very likely to be waiting for the Chen Qiming sisters to go home. The time when the murderer chose to go to Mr. Ma's house may also have this consideration.

Thinking of this, Ouyang Ping shuddered a little, if the above analysis and judgment can be established, then this will be a very tricky homicide case, because the murderer cut off all the clues when he committed the crime. This can also be confirmed by the fact that the murderer handled the scene after committing the crime -- the comrades did not take a single fingerprint related to the murderer at the scene.

After leaving the public shopping mall, Ouyang Ping and his entourage drove to the dry rest house -- the full name of the dry rest house was "Xiaguan Dry Rest House of the Jingnan Military Region of the Chinese People's Liberation Army." It can be seen that Chen Jialu's father is a retired cadre of the army.
