"Master Jiang, Director Gu, they have something to look for you."

"Master Cao, you lead Director Gu and them to sit in Hall 1, and I will come after nailing the soles of my shoes.

After five or six minutes, Master Jiang tilted his head and walked into Hall 1.

In addition to the things mentioned by Master Cao, Master Jiang provided three aspects of the situation;

First, the surname Ma often takes his wife to take a bath in the "guest often comes". Two people enter the bathhouse at the same time and leave the bathhouse at the same time, and both of them have a very expensive watch in their hands.

Master Cao also confirmed this: "Yes, the surname Ma does have a Longines watch, and every time he comes, he has to hand over the watch to us for safekeeping." ”

Second, the leather shoes surnamed Ma are made of the first layer of cowhide, and the trademark is Shanghai Leather Shoes Factory, which Master Jiang saw when he gave the spikes to the surname Ma.

"Master Jiang, are the leather shoes surnamed Ma new?"

If it is a leather shoe that you just bought, it may also be bought in Jingnan, and the shoes produced by the Shanghai Leather Shoe Factory can be bought all over the country.

"The shoes are ninety percent new, he came to mend the soles of the shoes, and the original soles have been almost worn out. Not only his shoes are produced by the Shanghai Leather Shoe Factory, but even his wife's shoes are also produced by the Shanghai Leather Shoe Factory. ”

"Shanghai Hongxiangyuan" customized cheongsam, "Shanghai Leather Shoes Factory" produced shoes, this information superimposed, what can be explained?

Some important information is hidden in some details of life, spiders must have silk, horses must have traces, unless the murderer encloses himself in a canned box.

It is possible that the murderer came from Shanghai, ran from Shanghai to Jingnan to seek revenge and kill, from living in No. 157 to leaving, then entering and leaving, before and after, it should have been premeditated -- it was planned.

No matter where the murderer comes from, the root cause of his evil must be in Jingnan, so if you want to find the couple surnamed Ma, in addition to investigating their origins, it is more important to start with Che Rengui's line. This is also Guo Lao's opinion.

Before waiting for the DMA appraisal results to come out, the five people did not rest, after careful research, we worked out several criminal investigation ideas, once the appraisal results came out, everyone worked according to the discussed ideas. Below, the author will first explain the criminal investigation ideas that everyone has discussed:

First, all the women who have been touched by Che Rengui must conduct in-depth and detailed investigations and interviews (Ouyang Ping and Liu Dayu regard this line as the most important one. In Ouyang Ping's memory, there are already two women, one is Lin Fengyan and the other is Huo Siyan. Lin Fengyan is the last woman Che Rengui touched before he 'ran away from home'; Huo Siyan is a woman who was once harmed by Che Rengui in that era when right and wrong were reversed, Huo Siyan was born in a merchant family, has received a good education since childhood, and is very beautiful, Che Rengui has long coveted Huo Siyan, Huo Siyan's husband has overseas relations, Che Rengui arrested Huo Siyan's husband on this ground, and used this to blackmail Huo Siyan into submission. Later, Huo Siyan committed suicide, and her husband became mentally ill and was admitted to Qinglongshan Psychiatric Hospital).

Director Gu said that Huo Siyan's mother is still alive, and her husband's illness has recovered later, and the school has taken care of him and let him work in the school library. If necessary, Director Gu can lead the comrades to find Huo Siyan's mother and husband.

Second, in addition to being lustful, Che Rengui was also greedy for money, and in that turbulent era, he took advantage of the chaos to make a lot of ill-gotten gains, and these people should also be the target of investigation (let's look back and think about what Director Gu said, it really can't be regarded as gossip.) Director Gu once mentioned a woman named Pan Guangmei. ）。
