"It's called Ermazi, and it's in the grain and oil business."

Ouyang Ping and Guo Lao, you look at me, I look at you, they thought of someone at the same time, everyone should know who they thought of.

Just now, on the way back to Moling, at Liuyedu, on the river, Liu Laosi's ferry boat and another boat full of sacks met, fortunately Liu Laosi avoided it in time, otherwise it would have crashed. At that time, Liu Laosi had a brief conversation with the other party, and Liu Laosi called the other party "Er Mazi".

In this world, there is such a coincidental thing, who would have thought that "Er Mazi" would enter the eyes of comrades in this way.

"Director Xu, where does Bao Yaqin's family live?"

"It's on the south bank of the Qinhuai River, and outside the backyard of her house is the river embankment."

"Does 'Ermazi' have a wooden boat?"

"It's really God, Captain Ouyang, how do you know?"

"Coincidentally, we heard the conversation between Liu Laosi and 'Er Mazi' at the ferry. At that time, I was a little puzzled, it turned out that Liu Laosi knew 'Er Mazi'. ”

"Ouyang, have you noticed that when we saw Er Mazi's boat, his wooden boat was going from west to east, it stands to reason that his boat should be going east along the south bank of the river, but his boat is traveling along the north bank of the river." Guo Lao Dao.

This is very easy to explain, Er Mazi is a native of Liuyedu, his family lives in the west of Liuyedu, he opened a grain and oil store on Moling Road, he wants to save trouble, and often drives in the opposite direction on the north bank. Usually, only a small amount of grain and oil is stored in the store, and a large amount of grain and oil is stored at home. ”

Ouyang Ping and Guo Lao finally understood what was going on. If Ermazi drove according to the rules, he should row the wooden boat from the north bank of the river to the south bank, then go east along the south bank, and finally row to the north bank of the river to unload, so that his boat would indeed have to make a bend, and if the water level was high and the flow speed was fast in summer, it would be even more troublesome.

"Where is Ermazi's grain and oil store?"

"On the east side of Moling Road, the straight-line distance from the crime scene is at most three or four hundred meters, from the vegetable field embankment, through the alley, to the east of a few shops."

This means that if Er Mazi's boat travels east along the north bank of the river from his home to the grain and oil store, the boat will definitely pass through the place where the crime occurred. Isn't that so? Ouyang Ping said.

"Exactly."

"If Er Mazi is the murderer, he only needs to tie the city wall bricks to the deceased's body, put them on the boat, and when he passes by the crime site, push the body and the city wall bricks down the water, and everything will be fine." Ouyang Ping said, "And you don't need to wait until midnight, as long as it's dark." ”

"The question is, why did he choose to sink his body in this place?" Guo Lao still has some questions.

"Now, what are we going to do?" Han Lingling said.

"There is no wind and no waves, there is no impermeable wall, the relationship between Bao Yaqin and Er Mazi should be true, but we can't alarm him for the time being, first find out where Chang Youkuan is now, and after it is confirmed that Chang Youkuan has an accident, it is not too late to find Er Mazi." Guo Lao Dao.

"Alright, let's go to Flora now." Ouyang Ping said.

The four of them walked out of the conference room and went downstairs.

At the top of the stairs, the four met Liu Daqiang, who came in a hurry: "Captain Ouyang, let's go to dinner first, don't wait for them." ”

"I can't eat for the time being, we have to go to Huashen Town."
