You could've made up the weirdest, most no sensical name for a fictional homicide victim name and dob, but decided to put the exact name and dob of very specific members of a really successful group of people with their official bdays. This is very unprofessional for the production team and the crew for allowing this to happen. Why not use the real names of the actors or band mates of another idol as homicide victims instead. After all, this is all for funsies.
