Not all readers.
But seriously, that's not a good enough excuse. Readers (or anybody) have no right to be privy to the feelings or emotions of a grieving family. If they want to give it willingly and come forward, then fine, that is their right. But for anyone other than someone specifically trained to deal with or therapise the feelings of grief to ask someone to speak candidly about how they are feeling, is hugely irresponsible. Who knows what they could be triggering.
Telling me what the parents of an murdered child or brother of a missing person is feeling does nothing to provide me with more facts or information about the incident.
Leave the fact collecting to the police.
Ironically it persists because that's what the readers want. But also because getting journos from lots of different outlets to do something is like herding cats. The fact remains that if they don't try to get comment they're not reporting the story properly.
