After the last incident with Chen, I became cautious and installed surveillance in my house.
So, once the police came and heard me recount the general situation, they immediately started monitoring the surveillance.
The surveillance records showed that someone first knocked on the door of the house. Auntie Wu should have known that when I wasn't home, very few people would visit.
So, she got very defensive and didn't intend to open the door when she saw through the peephole that it was someone she didn't know.
It never occurred to her that the person outside would get impatient and suddenly started kicking the door. Auntie Wu realized that something wasn't right and asked the person out the door loudly. The person outside directly demanded her to hand over the two children.
