Xiao Yu went back to the Criminal Investigation Brigade and reopened the case file.
He tried to stay calm and objective while analyzing the information and clues.
As he pieced together the details of the case, he had three main doubts: why was the victim on the roof at night, who else could have committed the crime besides the two female employees, and how did the murderer move the victim's body to the warehouse?
The other police officers were also working on the case, but they only had a short amount of time to solve it.
Xiao Yu remembered a similar case from his past and knew that it would take a lot of effort and mental energy to solve this one.
After analyzing and speculating for hours, Xiao Yu suggested going to the crime scene to gather more information.
In simpler terms, Xiao Yu was investigating a case and trying to think clearly without letting his emotions get in the way.
He had some questions about the case and wanted to visit the crime scene to gather more information.
When police detectives are in training, they are taught how to simulate a crime scene as a way to understand the criminal's actions and potentially catch them.
Guo Qiang agreed to go with Xiao Yu to the simulation site, even though it was difficult to do so at night, especially in the winter.
Guo Qiang recognized that Xiao Yu had a strong mind and liked his apprentice's ability to think deeply about the case.
He was willing to go with him in the hopes of discovering something useful for the investigation.
......
The police car returned to the crime scene and Xiao Yu didn't immediately go up to the roof of the staff dormitory.
Instead, he stood downstairs and imagined himself as the victim, trying to understand the actions of the murderer.
This technique is used in criminal psychology to simulate the crime scene and gain insight into the killer's actions.
As he imagined himself as the victim, Xiao Yu's brain became highly active and his adrenaline increased.
He realized that someone must have called the victim to the rooftop because it wouldn't make sense for them to go up there in the winter otherwise.
Xiao Yu suspects that the murderer may have called the victim to go to the rooftop, and the person who made the call could be the murderer.
However, there were no records of calls or social media messages during the approximate time of the murder.
Xiao Yu then realized that the victim was in the dormitory at the time, and someone could have gone to the victim's dormitory to call them to the rooftop.
The only people who could enter and leave the dormitory freely were factory workers, but surveillance footage showed that only a few employees left during the period, making it unlikely for them to have committed the crime.
Xiao Yu then considered the possibility of an outsider committing the crime, but there were guards at the dormitory entrance.
Finally, he thought about the possibility of the doorman being involved in the crime.
Xiao Yu's eyes flickered with a cold light as he considered the investigation.
The doorman had been suspected, but he was cleared based on his mobile phone records that showed he was playing a game during the crime.
While this eliminated the doorman, the possibility of an outsider entering the dormitory and committing the crime remained.
Xiao Yu was stumped, realizing that the murderer was highly intelligent and had left no clues.
He couldn't solve the case by simulating the crime scene, but he refused to give up.
Suddenly, an idea struck him and he began to consider the situation from the murderer's perspective.
