Lu Yun got up early in the morning, and after coming to Lin Lei's room, she found that Lin Lei was alone, and Li Xiaoan and Gu Li were nowhere to be found.

Seeing Lin Lei alone at his desk looking at the case file in his laptop, Lu Yun asked Li Xiao'an about their whereabouts: "Li Xiao'an, where did they go?"

Lin Lei closed the webpage he was looking at and said to Lu Yun: "In my plan, whether the murderer is in the liquidation alley or not, there is a job that must be carried out. However, this work is time-consuming and laborious, so I arranged for Li Xiaoan and Gu Li to find Officer Wang and ask him to help arrange manpower together......"

Lu Yun walked up to Lin Lei and asked curiously, "What job?"

Lin Lei smiled slightly, and slowly said three words in his mouth.

As soon as she heard these three words, Lu Yun was obviously stunned, and then quickly reacted, and asked with some surprise: "You check this? I'm afraid this is not easy to check, right?"

Lin Lei continued to smile: "Of course it's not easy to check, so I asked Li Xiaoan and them to check." With Officer Wang by his side, at least no one dared to deliberately conceal or perfunctory. ”

Lu Yun pondered for a moment, nodded and said, "Well, it's okay to check it out." It's been 20 years since the case happened......

Lin Lei rubbed his temples: "Try it and see how our luck is." ”

"Well, I can only treat a dead horse as Karamay-" Lu Yun was a little helpless and changed the topic, "Then what are we going to do?"

Lin Lei stood up, his eyes narrowed slightly, and said lightly: "Of course, I went to check the residence of those people in Pingcang Lane." I've checked the records that some of the places where they lived 20 years ago have been demolished, and some have not been demolished. ”

Lu Yun nodded slightly: "Okay, let's go take a look." ”

After coming out of the Sheraton Hotel, Lin Lei took Lu Yun to drive to the first place-

Emerald Road.

This is a street located five kilometers southwest of Dongda, as for why it is called Emerald Road, Lin Lei is not clear, anyway, the map shows that it has not changed much compared to 96 years.

As soon as they walked into Emerald Road, Lin Lei and Lu Yun had an eerie feeling.

The French plane trees on both sides of the road are said to have been planted in the fifties of the last century, and it is because of these plane trees that the Emerald Road has not been widened and rebuilt.

Originally, it was also going to be renovated, but after many petitions from old residents in the neighborhood, the renovation was put on hold.

126 Jade Road is where Dr. Wang of Chen's clinic originally rented.

In 1995, Dr. Wang separated from his wife and lived here alone.

The house is a five-storey building with only one unit, and Dr. Wang lives in room 103 on the first floor.

The house was a dormitory building for a nearby knitting factory, and the owner rented it out because he had other properties.

As soon as he walked downstairs to the unit, Lin Lei saw a policeman standing at the opening of the staircase door waiting for him.

Previously, Lin Lei had already contacted the police officer on Emerald Road, after all, it would be much more convenient to have a police officer in the house to investigate this kind of thing.

As soon as Officer Fang saw Lin Lei, he immediately greeted him: "Superintendent Lin, hello, I'm a police officer." ”

Lin Lei glanced at Officer Fang, smiled and nodded: "Officer Fang, hello." ”

Officer Fang is about fifty years old, and he is an old police officer in the area of Jade Road. The police station asked him to cooperate with Lin Lei's work, and it was obviously the city bureau who specially greeted him.

Twenty years ago, Officer Fang was in charge of the investigation of this area.

The two exchanged two more pleasantries, and Officer Fang took Lin Lei into Room 103.

The tenant who lives in room 103 has to go to work during the day, so Officer Fang came to greet him in advance yesterday and obtained a spare key.

Since Room 103 has had 7 or 8 tenants in 20 years, there is no point in surveying the current tenants.

What Lin Lei wants to see is not the current situation in Room 103, but some other things.

After entering the room, Lin Lei found that this was a one-bedroom house, about more than 50 square meters, and it would definitely not reach 60 square meters anyway.

This is an old house built in the eighties and nineties of the last century, and it was common to have a house of fifty or sixty square meters at that time.

The walls of the room are now covered with wallpaper, and the owner is also keeping pace with the times, although it is an old house, but it must be slightly renovated, otherwise it will not be rented at a good price.

"Officer Fang, did you go into the house to investigate back then?" Lin Lei looked at the wallpaper and asked with a frown.

Officer Fang was slightly embarrassed, he really couldn't figure out why this "Superintendent Lin" would come to investigate his jurisdiction.

"Superintendent Lin, we are five kilometers away from the scene of the crime, outside the key area. At that time, the focus of the Dongda corpse mutilation case was three kilometers around the scene of the crime, but the scope was later expanded. ”

After a pause, Officer Fang continued: "Superintendent Lin, you also know that if the radius of two kilometers is expanded, the number of households that need to be investigated will be astronomical. At that time, we mainly relied on the public security joint defense team members in the jurisdiction to conduct household investigations, and there were no clues to reflect. ”

Lin Lei nodded slightly, indicating that he understood.

Lin Lei knew very well that there were as many as 50,000 households within a three-kilometer radius of Dongda alone. If the scope is expanded to a radius of 5 kilometers, the target of the investigation will be at least more than 100,000 households.

Because of this extra two-kilometer radius, it happens to be the densely populated area of Dongfang City.

It is simply impossible for so many households to rely on the police to investigate one by one.

However, the impact of the case was so bad that the police had no choice but to investigate it -- so it was the proper intention to mobilize the masses and rely on the "joint security guards."

This is a very normal thing, and it is not what some netizens think - it seems that as long as one mouth, you can check the entire Dongfang City......

If it is investigated by the public security joint defense team, then there is a possibility that the scene of the dismemberment will escape the investigation.

Previously, Lin Lei's premise was that professional police officers would not miss the scene of the dismemberment, but it did not include "public security joint defense members".

Lin Lei came to the kitchen, which was also very small, and could only accommodate one person to cook and cook in it - neither of them could do it, there was no room to move around.

Lin Lei opened the kitchen window and stretched out his head to look around.

The room is on the ground floor, and a meter away from the kitchen window is a fence, and there is a lot of garbage on the ground, apparently done by the upstairs residents......

The windows are only a meter away from the outside wall, and this is obviously not a passageway, and no one will walk in this kind of place.

"Twenty years ago, was this the case?" Lin Lei asked Officer Fang behind him.

Officer Fang nodded: "Well, nothing has changed. ”

After a pause, Officer Fang added: "This is the dormitory building of the knitting factory, and after the bankruptcy of the knitting factory, the workers got a lot of money. Many people bought houses outside, and the old dormitories were rented out. ”

Because the kitchen was too small, Lu Yun didn't go in, and she and Officer Fang were standing by the kitchen door.

Lu Yun asked casually: "Officer Fang, was this place full of people back then?"

Officer Fang shook his head and said, "The incident happened in mid-January, and it was already the end of January and the beginning of February when we started the investigation. At that time, it was the Spring Festival, and many tenants went back to their hometowns for the New Year. When the building was investigated, almost all of the landlords used spare keys to open the door for the survey, and most of the original tenants could not find it. ”
