That little girl?
If we're talking about the people and things Xiaofan came into contact with, the only one left unchecked is that girl.
Because the girl was badly frightened, when the police were taking statements they only had her guardian come out and explain.
So when Xiaofan picked that little girl up, did he not say anything to her?
Right now, the only lead left to find Xiaofan is that little girl. With Xiaofan's level of intelligence, it's not impossible he'd do something like that.
"Hello, is this Captain Chen? I'm Li Kuo, I was at the station today. Mm, could you give me the address of that mother and daughter from the restaurant last time? Yeah, it's urgent, sorry to trouble you."
In less than five minutes, Li Kuo received their home address and phone number.
It was already close to ten at night, so they were probably resting.
But with things this urgent, Li Kuo had no choice but to call and disturb them.
