The new addresses of these four families are: Zhang Bingkun, No. 187, Shangying Lane, West Zhimaying; Men Xuecai, No. 396, 43rd Street, Chaotian Palace; Zhao Yaru, No. 17, Zouma Lane, Qili Street and Hepingli. Gan Dejun, No. 473, Dongting Street, Hanxi Road.

Director Wang specially asked Rao Ping, a housing manager from the district housing management office, to guide the comrades, and the 17 families were scattered in different places, and Rao Ping was very familiar with these places -- Rao Ping was mainly responsible for collecting rent.

The first object of investigation is Director Wang, coincidentally, Director Wang is very familiar with Xie Juren Lane, Director Wang once worked as a household registration police officer in Xie Juren Lane, so he is more familiar with the head of Xie Juren Lane.

Director Wang also called Tang Xiaozhang, the current police officer of Xie Juren Lane, who served as a police officer in Xie Juren Lane in 1993.

Tang Xiaozhang's answer made Ouyang Ping a little disappointed:

We summarize the content of Tang Xiaozhang's answer into two points:

First, in the past two years, there has not been a case of missing persons in Xie Juren Lane -- if anyone is missing, it is impossible for them not to know that Xie Juren Lane -- including the entire area under its jurisdiction, has no one mentioned the disappearance of a person in front of him, let alone reported the case to the police station.

Second, there are no cases of missing people from the four families living in the Chen family's compound. Tang Xiaozhang can even name each of the four families and their recent situation.

Director Wang also confirmed Tang Xiaozhang's statement, and he also further proved the credibility of Tang Xiaozhang's statement from the side, in last year's annual assessment, Tang Xiaozhang was rated as an excellent film police officer by the Municipal Public Security Bureau, Tang Xiaozhang worked in Xie Juren Lane for less than a year, and he can remember the names of all the people in the jurisdiction and the work unit. No matter who you know from Tang Xiaozhang, he can count all the treasures.

Tang Xiaozhang remembers very clearly the time when 17 families were relocated, because he and two other policemen from the police station participated in the relocation work, and he also helped find the car; the time when the four families in the Chen family compound moved was on the morning of September 7, 1994, plus the three families in the "Xie Xi's former residence"; in the afternoon, the six families in the "Xie Xi's former residence" and the other four families moved on the morning of September 8. These situations are recorded, and there will be some costs involved in helping the demolition households move, and since it is related to money, it must be recorded.

September 7th and September 8th, this time proves Guo Lao's judgment of the time when the deceased was killed from another aspect. Earlier, the author has already said that this case is not unrelated to the demolition of four families.

The demolition time of the four families is September 10th to 15th, a total of six days of demolition, that era, the demolition of the house and the demolition of the house is not the same as the current demolition of the house, the level of economic development is still relatively low, in the process of demolition, all the building materials that can be reused, such as doors and windows, bricks and tiles, wood, are used, except for the broken bricks and tiles and the wood that has been hollowed out by ants, the same can not fall. There are many public houses under the jurisdiction of the district housing management office, and almost all of these houses are old houses, so they need to be repaired regularly, and building materials such as doors, windows, bricks and tiles are needed for repairs.

Regarding the well closely related to the case, from the time of abandonment to the time of piling up construction waste, Tang Xiaozhang remembers it very clearly:

On August 1, 1994, four families who originally lived in the Chen family's compound funded the digging of the well, and the leader was Zhao Yaru, and everyone felt that the water quality was not as clear as several other wells nearby.

As a result, the well became a place for dumping garbage. Later, someone reacted to Tang Xiaozhang and dumped garbage into the well, for a long time, especially in summer, the garbage fermented in the well, the smell was unpleasant, affecting the environment, and more importantly, children often played by the well, in case of an accident, it was a matter of human life, so Tang Xiaozhang took a few residents to seal the wellhead, and the people who covered the two bluestone slabs on the wellhead were Gan Dejun and the third man.

The murder of the deceased should have been after the well was abandoned, and this time is also relatively close to Guo Lao's judgment of the time when the deceased was killed.

As for when the edge of the well and the long stone below the edge of the well ran to the bottom of the well, Tang Xiaozhang did not know.

The careful Ouyang Ping also asked Tang Xiaozhang to draw a sketch of the environment at the scene of the crime, which is very necessary, time has passed, and the occurrence of the case is inseparable from the original environment, now, there is only a pile of ruins left at the scene of the crime, if you want to solve the case, you must figure out the original environment, according to the time when the deceased was killed, it should be after the well was abandoned and before the demolition - at least in the process of demolition. All the clues and relevant information of the case must be hidden in the original environment.

According to Ouyang Ping's request, Tang Xiaozhang sketched the original environment around the crime scene. Below, we will explain this sketch a little.

The Chen family compound is in the south of the "Xie Xi's Former Residence", there is a road between the Chen family compound and the "Xie Xi's former residence", and the gate of the Chen family compound and the gate of the "Xie Xi's former residence" are opposite each other - the gate of the "Xie Xi's former residence" is a little easter, and the gate of the Chen family compound is a little westerly.

The house in the Chen family's compound is two-in, with a small yard in the front and back, and the location of the well is in the backyard. If you go to the Chen family compound to use well water, there are two paths, one is from the front yard door, through the foyer between the Zhao and Gan families, and into the backyard, the residents in the "Xie Xi's former residence" walk through the front yard door; The other path is the back gate of the Chen family compound, and there is a long and deep alley called Shigu Lane to the west of the Chen family compound.

Enter the alley, walk more than 30 meters to the south, there is a courtyard door on the left hand and the right hand, enter the backyard of the Chen family compound on the left hand, the well is more than ten meters away from the small gate, enter the right hand courtyard door is the Cui family compound, there are seven families living in the Cui family compound, these seven families all go to the Chen family compound to use water (because there is no well in the Cui family compound), there are four courtyards in the alley, there is a courtyard in the south of the Chen family compound, this courtyard has no name, and a small door is the only way to enter this courtyard. There are five families living in this courtyard; There is also a courtyard to the south of the Cui family's compound, and there are nine families living in this courtyard; This yard is called Qijia Dyeing Workshop (it was a dyeing workshop before liberation). In the four courtyards, there are only two wells, in addition to the well in the Chen family compound, there is also a well in the Qi family compound, and the residents in the other two courtyards either go to the well of the Chen family compound to use water, or go to the well of the Qi family compound to use water.

When Ouyang Ping and his entourage of five walked out of the police station, the time was a quarter past four.

Ouyang Ping decided to start their investigation with the four families in the Chen family's compound.

The police car crossed Chaotiangong Avenue and headed east.

About ten minutes, the car stopped at the north head of a small stone bridge, the name of the small stone bridge is Qili Bridge, after the Qili Bridge, it is Qili Street, Zhao Ya Confucianism lives in Qili Street. The reason why I visited Zhao's house first was because Director Qi said two words casually:

"You can go to Zhao Ya Confucianism to investigate first, the well is only a few steps away from the window of the Zhao family."

"Zhao Yaru's eldest daughter is thirty-six years old, but she is still not married."
