"There are two breakthroughs in the current situation."
Luo Fei looked at the few people beside him.
"First, although the perpetrator entered the building, his coming and going methods are different and he wasn't in a hurry. This indicates he is familiar with the layout of the building and the surveillance blind spots in the community. There aren't many people like that."
"Delivery personnel, couriers, security guards, even those who deliver milk are all suspects, but they must have a connection to the victim's family, and only through binding investigation can we solve the case."
"Second, this person is extremely familiar with the victim's household, even knowing the location of the kitchen knife. This indicates he must have had prior access."
Hearing this, everyone's expressions turned serious.
In this way, the investigation scope and the direction of suspicion are basically determined.
"All the surveillance footage needs to be reviewed over the recent period."
