Song Guiyi asked for the address of the mall and the location of the abandoned car. He ate lunch casually and rode his bike to the mall. As if to avoid some painful memories, he had not ridden a motorcycle since breaking up with Li Su. The mall is in the west of the city, a bit remote. There are two residential areas nearby, but it is unlikely that the perpetrator lives nearby. This kind of hijacking case is not like a murder case. The perpetrator will not reminisce the pleasure of committing the crime. The crime scene is usually far away from home, trying to distance himself from himself.
Simple robbery cases are the most difficult to solve. First of all, these cases are highly random, and the perpetrators and victims do not have much contact, so it is difficult to lock the target simply by checking their social relationships. In addition, the perpetrators are highly mobile and often flee to other cities after committing crimes. If there are no particularly strong clues within a week of the crime, these cases will often become unsolved cases. And robbery cases like this, where even the victim's body cannot be found, will be even more troublesome. From a cold point of view, the body is usually the best evidence, and the murderer's DNA can be extracted most of the time.
Song Guiyi despised this kind of criminals more than simple murderers, because they were able to stay at large not because of careful planning, but often because of great luck. And catching them sometimes also depended on luck.
Song Guiyi's on-site visit was mainly to confirm whether the whole case was a premeditated crime or a random crime. From the existing clues, the possibility of a random crime is small. The perpetrator may not be an acquaintance of the victim, but at least he knew her and may have had some contact with her in work and life.
The underground garage is not large, occupying only one underground floor. According to the information Li Jiu provided in the email, on the night of the incident, his wife parked the car in parking space G13. Song Guiyi put his hands in his pockets and walked around the garage from beginning to end, and found the unreasonable location of the surveillance. Because there is an elevator directly to the mall from Area A to Area C, more than two surveillance cameras are arranged in one area. However, after Area D, the farther the parking space is from the exit, the weaker the surveillance arrangement. When it comes to Area G where the accident happened, it shares the surveillance on the aisle with the adjacent Area H, which creates many blind spots in the surveillance. Just by taking a simple walk like this, he can find two routes that completely avoid surveillance, enter from the back door, and quickly reach the location of the crime.
