And based on the known identity information, going to the hotel he checked into last night didn't yield anything.
As for his family and friends...
His father died long ago, and after his mother remarried, she basically let him be, so he was quite rebellious since childhood, later sent to the army, and after being discharged, he's been drifting through society.
Although he didn't break any laws, he never had a stable job, hopping from one to another without achieving anything, rarely returning to his hometown, and his mother and other relatives are completely unaware of his recent circumstances.
The retrieved call records, along with comprehensive societal information, show that his recent job was as a ride-hailing driver, and several people he recently contacted were ordinary passengers who paid to ride with him.
