At the crime scene in Baoshan District, I stayed until two o'clock in the afternoon and finished my work. At this time, everyone had not eaten yet.
Jiang Hao and Du Guoping returned to the city, ate a bowl of instant noodles, and then returned to the branch office.
At the door of the branch, Jiang Hao couldn't help with the things Du Guoping wanted to arrange, but fortunately he didn't cause trouble, so the two parted ways at the door.
Jiang Hao took the file bag that Wang Shaodong gave him and took a taxi back to the Public Security Bureau.
Sitting in his office, he took out the document from his file bag again.
Wang Shaodong is really very careful in his work. Not only does he record all the enterprises, Jiang Hao even found a land planning map of Longqiao Town Government 19 years ago, the location of various enterprises and residential land in his file bag.
There are numbers on the map.
This is so considerate. Even the case with a high person does not have such a comprehensive and systematic planning diagram.
It can be seen that Jiang Hao only said his own requirements, and Wang Shaodong fully understood his needs, even exceeded the task, and brought a map.
It has to be said that being able to be the captain of the Criminal Investigation Detachment of the branch is definitely a reflection of outstanding ability.
Putting the map aside, Jiang Hao first studied this table.
19 years ago, in Longqiao Town, there were 256 registered enterprises, of which 23 provided accommodation conditions, and the rest were small and micro enterprises, and there were no conditions to provide accommodation.
The situations of these 256 companies on the list are listed in very detailed details. If the murderer is really a migrant worker, he is likely to be in one of the factories.
Because according to the conclusions drawn by the police before, you are not a local person and you must be familiar with the terrain. If you are just a foreigner who came here to travel, you cannot be so familiar with the surrounding environment. Only those who work here and live for a while,
It is possible to be so familiar.
The murderer committed the first crime on December 12. According to the calendar of that year, the Spring Festival was February 1, which means that there was about one and a half months left before the Spring Festival.
Jiang Hao looked at all the companies on the list, but did not find that one company would be put on such early holidays.
It is the earliest company that has the holiday, and it only takes the holiday on the 15th day of the 11th lunar month, and other companies are around the 28th day of the 11th lunar month.
This conflicts with Jiang Hao's previous inference that the murderer went home to celebrate the Spring Festival after the case was committed, because the company's holiday time was not up to par.
"Are my guess wrong?"
The development of the matter was somewhat beyond Jiang Hao's expectations. He originally thought that Wang Shaodong would bring back the information and simply compare the company's holiday time to lock in the factory where the murderer was located.
But reality is always cruel. If it is so simple, I believe that more than 200 task force police officers 19 years ago would not have been able to find it.
"The reason why the case that has been covered in 19 years is that I think it's simple."
Although the final comparison result did not match, Jiang Hao was not discouraged. He was ready to fight the tough battle as early as when he took on this task. However, this clue was wrong, just change it.
Jiang Hao turned on his mobile phone and looked at the contents of their Double 12 project group. Group 1 and Group 2 have already begun to feedback their current investigation content in the group. However, the investigation is very difficult. Archives from 19 years ago, save
Nothing bad is gone, and even the rest is incomplete.
But even so, they did not give up, and kept flipping through the remaining files and then summarizing. When they meet the conditions of the suspect, they will also notify three groups in the group so that they can start to take action and go to the other party.
address, collect DNA data.
Of course, not everyone needs to collect the suspects who have been collected by the task force 19 years ago, their data is already in the database, so there is no need to go there, just pick the fish that missed the net.
Relatively speaking, there are much less.
"It's hard to say whether the case can be solved in 20 days like this."
At the meeting, Jiang Hao's awesomeness had already been hyped up and said that he could solve the case in 20 days, but that time was the time required by the system. If it was not completed, his task would also fail.
If the system mission fails, although there is no punishment, if the show fails, it will reduce his reputation in the hearts of the team members!
Jiang Hao rubbed his eyebrows. In order not to lose his prestige and make others think that he is a big talker, he must come up with ideas as soon as possible to guide all the members of the Double 12 project team to work hard.
"It is known that the murderer is not a local and is familiar with the local environment. Then he must have lived in Longqiao Town for a while, so his identity as a migrant worker is basically clear, which means that this idea is not wrong.
If the company is looking for the wrong direction, which company will have a holiday one and a half months in advance?”
Jiang Hao took out the form again, and 256 companies appeared on the paper, but none of them could match the Spring Festival holiday.
"Can't it be said that the murderer still went to work calmly after committing the crime?
It’s impossible. If he is so heartless, how can he escape the police’s first interrogation?”
Jiang Hao found that the more he investigated, the more problems he had appeared, and he himself became more and more confused.
"No, I want to abandon all the investigations of my predecessors. The more I know, the more I will affect my judgment. If time goes back to 19 years ago, on that sleet night, the murderer committed the crime for the first time and threw the body,
Two days after the crowd called the police, I happened to be out of the scene, so what would I do?"
Using the substitution method, in terms of thinking, Jiang Hao successfully traveled through time and returned to 19 years ago. As the police officer who served at the time, he was the first to arrive at the scene. What would he do?
Thinking of this,
Jiang Hao immediately took all the extra information on the case analysis board, but left behind the photos taken at the scene of the crime, and carefully observed the photos to see if there were any missing details.
The place where the murderer threw the body was not hidden. It can be said that there was no disguise. Anyone who passed by would be able to find the bare body lying on the cold mud floor at first sight.
What does this mean?
It means that the murderer has no car!
If he had a car, the first thing he thought of was to find a hidden place to throw away the body.
Not only that, it also reflects from the side that this is likely not a premeditated crime, but a passionate crime.
The murderer's method of throwing the corpse was very unfamiliar. At night, he threw the corpse with a naked body on his back. At that time, the murderer's first idea was to take off his hands as soon as possible, and not let people see it, and then he would consider throwing it.
