Du Dayong and Luo Xin quickly arrived at the family building of the Grain Bureau. This family building was built in the 1970s. Most of them are five floors. There is no exterior painting, and all the red bricks are exposed.
The people currently living in the entire family building are basically the elderly or immigrants.
The trash cans in the Jialialou community are distributed at one end, one at the end and three in the middle. Two of them are garbage pools surrounded on three sides.
According to the recollection of the truck driver at the time, the snakeskin bag was loaded into the truck at the rear of the family building, and the driver believed that the snakeskin bag should have been packed between 3 a.m. and 5 a.m.
put in.
Because such open family buildings usually have garbage pickers, and the garbage pickers usually end their night-time garbage collection around three o'clock in the night.
The time when the collection trucks arrive here to remove garbage is usually around five o'clock in the morning.
Therefore, Du Dayong felt that the driver's judgment should be reasonable.
So if you know this about the cleaning time and garbage pick-up time, you should not be very far from here, or you are quite familiar with this family building.
However, the investigators at that time conducted a survey of the neighborhood and the entire family building, but all of them were excluded.
The investigators then tried to make a breakthrough through the missing persons in this city and surrounding cities, but after nearly half a year of investigation, they still had no clue. The missing person and the female corpse could not be matched.
Therefore, the case has reached a stalemate at this stage. As other cases occur and increase, although this case is of a bad nature and cruel methods, there is no way to make an effective breakthrough.
Du Dayong looked at the entire Grain Bureau's family building, but he felt in his heart that the murderer actually deliberately misled the investigators to conduct a point-to-face investigation of this place, so that he could break out of this inertial thinking method.
Du Dayong then went to the Family Building of the Education Bureau and the Clearwater Bay Community Waste Treatment Center.
But after looking around, Du Dayong also had no clue.
As for some entertainment venues, investigators at the time had already conducted investigations, but there were no clues. There were no escorts from entertainment venues missing in this city or surrounding cities at that time.
Du Dayong felt that the difficulty of this case was that he did not know who the deceased was, and the murderer deliberately removed the head, feet and chest, possibly to confuse the investigators at the time.
Because this will allow investigators to conduct searches based on the obvious features of the feet or chest. www.bǐqυgetν.℃ǒm
Perhaps the biggest purpose of the murderer is to make the investigators do useless work among seemingly numerous clues, so as to confuse the facts and delay the investigation progress of the case.
Once a case is delayed longer, fewer and fewer effective clues will be obtained, and some supporting evidence of the case will gradually lose its supporting value as time goes by.
Du Dayong believed that the murderer should be a thoughtful one with clear logical thinking and certain medical skills.
He also has a good understanding of police investigation methods and has strong counter-investigation common sense.
Then the criminal suspect roughly established a template in Du Dayong's mind.
Du Dayong believes that criminal suspects should have a certain cultural foundation and have an independent residence or an independent residence other than an independent residence.
Criminal suspects also have strong psychological qualities, and they also have countermeasures or methods to deal with police inquiries or investigation.
In addition, the murderer should have transportation, at least a motorcycle or above.
The criminal suspect's personality has obvious duality. Perhaps under normal perception, the suspect should be a gentle and gentle person, but secretly he is an extremely psychologically distorted person.
Du Dayong personally believes that the suspect's residential center should be elsewhere within these three local areas.
Du Dayong opened the map and slowly searched for the reasonable psychological comfort zone of the criminal suspect in this area.
