"Computers are very expensive, and most people can't afford them, and people like us don't even think about it, Mr. Li only sells computers to parents of students with particularly good economic conditions."

Mr. Ma's family is fully eligible.

The information provided by Men Haoran is very important.

After sending away Menqiusheng's father and son, Ouyang Ping, Liu Dayu, Chen Jie and Zuo Xiangdong went to Teacher Ma's house again.

When Ouyang Ping told Mr. Ma's father and daughter about the contents of Chen Qidi's diary and the information provided by Men Qiusheng's father and son, Mr. Ma was silent for a long time, and then said: "Why didn't I think of this person - I should think of him, Li Dongting did sell computers to students' parents in private, I just heard about it, one is willing to fight, one is willing to suffer, as long as the parents don't say it, the school leaders will not ask about this kind of thing, this person is usually very active, and has a good relationship with the leaders, and more than a dozen computers in the school are bought through him, He had a cousin who worked as a leader in an electrical appliance store, and nine times out of ten he got his computer. ”

"Where did you buy your two computers?"

"My wife handled the computer purchase, and he didn't let me ask about the big and small things in the house."

"Is the invoice for buying a computer still there?"

"I don't know about invoices, and my wife never let me see them. I've always been against my wife's style of acting, she's too flamboyant and too ostentatious. So, there are some things that she often hides from me. These two computers were probably bought from Li Dongting's hands, and with Li Dongting's three-inch incorruptible tongue, he wanted to fool Mr. Liu, which was a flicker. Did the two children mention Li Dongting in their diaries? ”

"No, we went through the diaries of the two children, and they only mentioned the computer, but they didn't mention Mr. Li. Teacher Li's illness was mentioned by Chen Qidi once. ”

"They should know, or they wouldn't—" Teacher Ma's eyes filled with tears, "I only know that the old woman has a loose mouth, likes to show off, and acts domineeringly, and I have criticized her more than once, but she has repeatedly taught her - I did not expect to invite the disaster of murder - all blame me for being too good at talking, and let her do everything." ”

"How much do you know about Teacher Li? What kind of disease did he have? ”

"I have very little contact with this person, he was transferred to our school a few years ago, he used to teach in a rural primary school, that is, Heizha Camp Primary School, and later, through his connections, he recognized Gao Chengxiu, the deputy director of the district education bureau, as his godmother, and I estimate that he was transferred to our school because of the contribution of the deputy director Gao."

"Chen Qidi mentioned Li Dongting's illness in his diary, what kind of illness did he have?"

"In this school, there are not many people who know Li Dongting's details, and I have heard in private that Li Dongting has suffered from mental illness before."

According to Men Haoran's description, Li Dongting's body does have traces of mental illness.

"Mental illness?"

Ouyang Ping immediately realized the seriousness of the problem, and we all know that if Mr. Li is indeed mentally ill, even if he is the murderer of Mr. Liu's family of three, he may not need to pay criminal responsibility.

"Some of the teachers said that in private, but they never saw him sick at school. It is said that when I first got this disease, it was not very serious, because the treatment was timely, and after hospitalization, I was cured later. ”
