The owner of the convenience store was asked about his interaction with Jonghyun at the store, and he said that Jonghyun had only bought some cigarettes, a soda drink, and some snacks.
The security guard also spoke about Jonghyun saying:
“After parking his car on the B1 floor, he stood in front of the convenience store on the same floor for a very long time. After checking in he got in his car and went to the road right in front of the residence and went back and forth making a lot of noise. He was stepping on the accelerator so hard that the engine was making very loud noises. After a while, things got quiet and then the car came back in (to the parking lot).” -Security Guard
