Zhao Mingtao, age: about 35 years old; From July 1986 to the end of the year, he rented the first Westinghouse; Current address: No. 197, Sanming Street, Shuizuogang; Work unit: Nanjing Wuzi School (driver).

Wang Zhongkui, age: around 50 years old; From August 1986 to March 1987, he rented the first east house; Current address, unknown, employer: Baixia District Tobacco and Liquor Company (salesperson).

Chen Hongmei, about 40 years old; From November 1986 to March 1987, he rented the second east house; Current address: unknown, work unit, warehouse (administrator) of Baixia District Material Company.

Mrs. Gao, age: about 70 years old; From November 1986 to January 1987, he rented the second Westinghouse (the second son got married, and the old lady vacated the house she lived in for her son to get married, and moved to No. 157 by herself).

Ma, from May to July 1987, rented the second Westinghouse.

Qin Dacang, 45 years old, rented a second and three houses from July 1987 to January 1988

Zhao Zimeng took out a pen from his pocket and crossed out the names of five people, who were Zhang Guangnan, Gong Caiju, Wang Zhongkui, Chen Hongmei and Mrs. Gao.

In the tenant information provided by Che Huating, only two people surnamed Ma and Zhao Mingtao remained.

As everyone knows, the surname Ma has been ruled out on the grounds that the surname Ma had lived at No. 157 twice, the first time in the second three-room room, and the second time in the second Westinghouse - according to the time, the second time the surname Ma was stationed in No. 157 after the deceased was killed.

Now, there is only this Zhao Mingtao in front of everyone, everyone knows that Zhao Mingtao, comrades have already been in contact, judging from the content of the inquiry, Zhao Mingtao has no problem. Now, the comrades have to re-examine Zhao Mingtao's statement.

When Zhao Mingtao lived in Impermanence Lane, he was the only one at No. 157, and after he moved in, about half a month, the surname Ma moved in, which was one of them. The investigation should revolve around this period of time.

Second, Zhao Mingtao is a driver, he went back to No. 157 at night (this is Zhao Mingtao himself said), at night, because of well-known reasons, there are fewer people walking around the alley, at this time to carry lime and cement, it is not easy to be found by neighbors, Xiang Daimo is right, from the thickness of the lime layer of the wall, the amount of lime used is not a few, and the car can solve the transportation problem.

Now, it is necessary to find out whether Zhao Mingtao is driving a car or a big car - judging from Zhao Mingtao's statement (driving for the leader), it should be a small car, but it needs to be further verified.

Third, Zhao Mingtao is not married in his thirties, is there any other reason besides the reasons he stated?

Xiao Luhan felt that the surname Ma was a little suspicious, and as for what was suspicious, he said it was not good: the following points supported this idea:

First, the time when the surname Ma rented No. 157 was very close to the time when the deceased was killed.

Second, the first time the surnamed Ma rented a third house, one of which was the scene of the crime.

Thirdly, the second time he rented was the second Westinghouse, which was next to the East Wing, and during his stay in the Westinghouse, the East House may have been vacant – for well-known reasons, House 157 was often vacant.

Fourth, in the process of investigation, this surname Ma appeared many times, and it was impossible for everyone to bypass him.

Fifth, the reason why everyone excluded the surname Ma was that the surname Ma had been stationed at No. 157 twice. If we think backwards, this person surnamed Ma should be the focus of the investigation – at least the subject of the investigation, because the more unlikely it is, the more likely it is.

Sixth, now, only Zhao Mingtao and the surname Ma are the only subjects of the investigation. Xiao Luhan naturally thought of the surname Ma.

Zhao Zimeng paid enough attention to Xiao Luhan's thoughts, and on the materials provided by Che Huating, Zhao Zimeng drew a small door number behind the tenant surnamed Ma, and after some tenants were excluded, the tenant surnamed Ma seemed more eye-catching.

Zhao Zimeng decided to do some more in-depth and detailed investigation around Zhao Mingtao first. Fortunately, there are only two people left in everyone's sight, and after solving Zhao Mingtao's problem first, it is not too late to investigate the surname Ma.

Everyone knows that it is not easy to investigate the surname Ma, the surname Ma is a foreigner, what kind of place is he? The comrades didn't know anything about where this person came from, not even the owner Che Huating. Only Zhao Mingtao has had contact with the surname Ma.

Judging from the information provided by Zhao Mingtao, he and the surnamed Ma have never even had a verbal exchange and communication, so it is unlikely that they know who the surname Ma is. Even if the investigation of the surname Ma is to be launched, it should start with Zhao Mingtao, although he and the surname Ma have no contact, but they have lived in the same courtyard for more than a month, it is impossible not to know a little information.

Of course, Che Huating is also an important path, and he has had contact with the surname Ma.

After having breakfast and leaving the police station, Zhao Zimeng and his entourage came to Aunt Li's tea stove.

The time is around half past seven, and at this time, there is no business for the tea stove - during the day, around half past six in the morning and around seven o'clock in the evening, the tea stove is at its busiest.

Xiuqin next door is removing the door panel - there are more than a dozen door panels on the street side of Xiuqin's fried food shop, and after the door panel is lowered, a long simple counter is exposed.

After Xiuqin finished getting off the door panel, she also walked over.

"Aunt Li, after Chen Hongmei, there is a person named Zhao Mingtao, who also lived in No. 157 for a while, do you know him?"

"Zhao Mingtao, isn't it Xiao Zhao who is a driver in the material school?"

After more than five years, Aunt Li can still remember Zhao Mingtao.

"Auntie, you really have a good memory!"

"Xiao Zhao, on this street, there is no one who doesn't know him." Xiuqin said.

"What a warm-hearted young man! One night, my little granddaughter suddenly complained of a stomachache, and Zhao Mingtao happened to come to boil the water, but without saying a word, he took my granddaughter to the children's hospital in a car. ”

"Does Zhao Mingtao drive back every night?"

"Yes, he drives back every night - Xiao Zhao goes out early and returns late every day - he has to come to me every night to boil water."

"This road is not wide, where is Zhao Mingtao's car parked?"

"He had to park his car every night in the square in front of him." Aunt Li pointed to a square not far away and said, "Look—it's right there." Before liberation, it was a place where horses were bought and sold. Walk a little further and you'll be able to see it. ”

Zhao Zimeng followed the direction of Aunt Li's finger, and not far away, across the road, there was indeed a recessed place, and several old men were sitting - or standing at the small table playing chess - or watching the game of chess.

Zhao Zimeng was about to ask about the car, but Aunt Li said it first.

"What kind of car is Zhao Mingtao driving?"

"He's driving a car."

"When does he usually come back every night?"

"It's usually around seven o'clock, sometimes around eight o'clock, and if it's a little later, I don't know."

"Did he park his car at the entrance of the alley?"

"I haven't seen it." Aunt Li shook her head.

"I've seen it." Xiuqin said.

"Did he move anything down?"

"Moved."

"What's moving?"

"It's a cardboard box."

"How many cartons?"

"It's quite a lot, he moved it several times, maybe four or five cardboard boxes, or five or six cardboard boxes."

"Isn't the carton heavy?"

"It's very heavy, and I see that he is struggling to move."

"How big is the carton?"

"Cartons are big and small, big ones are so wide, so long, so high; The small ones are so long, so wide, so tall. Xiuqin gestured with her hand a few times.

According to visual inspection, the length of the large carton is 60 or 70 centimeters, the width is 50 or 60 centimeters, and the height is also forty or fifty centimeters; The length of the small cardboard box is fifty or sixty centimeters, the width is forty or fifty centimeters, and the height is thirty or forty centimeters.

"With so many cardboard boxes, can the car be put down?"

"Some are in the car, some are in the box in the back of the car, otherwise how can I see?"

"Is Zhao Mingtao moving alone?"

"He's the one who moves alone. He was like he was throwing something upside down - eighty percent of what kind of business he was doing. ”

"And after that?"

After that, he parked the car in the square in front of him.

"Later, did you see him move the carton out of No. 157?"

"Nope."

What's inside the carton?

"How many times have you seen this happen?"

"Several times."

"Is there a long time between them?"

"Not long, a few days in a row."

"When Zhao Mingtao lived at No. 157, did he interact with anyone?"

"We haven't met, he doesn't come back until after dark every night, sometimes it's late, auntie, what do you say?"

"I haven't seen him interact with anyone," Aunt Li pondered for a moment, "By the way, Xiao Zhao has a habit of taking a bath, he has to go to the 'guest often come' every night to take a bath, he will put the hot water bottle here with me before taking a bath, and then take the hot water bottle away when he comes back." ”

"You can go to the 'guest often come' to ask, or you can ask the shoemaker Master Jiang, whose shoe stall is placed at the door of the 'guest often come', and Jiang Weizi closes the stall very late every night. You can also go to the bathhouse and ask the runners. ”

Aunt Li's mind is not confused at all, and there are two alleys in the north and south of the "Impermanence Lane".

After stepping out of the tea stove, several people walked through the alley of impermanence.

Walking out of the north alley, I saw a shoe stall at a glance, an old man about seventy years old was cutting the skin nailed to the sole of the shoe with a knife, the knife was very sharp, and the excess part of the leather was quickly separated.

Director Gu stepped forward: "Master Jiang, you are busy. ”

"It's Director Gu." Master Jiang tilted his head and looked at Director Gu and Zhao Zimeng and his party.

"Master Jiang, let's ask you about something."

"Director Gu, you must be here for the case of 'Impermanence Lane', you ask! As long as I know. ”
