Changwon motel accident that killed 3 people, seems to have been a result of a conditional meeting threat

I called a girl through an app, but the condition was that she was a minor.

Reporting by meeting

It seems like the boys chased them together and then threatened them for money.

You should lock the door, hit and intimidate, but instead

It looks like a man in his 20s killed all three people on the spot.
