The Disappearance of 'Famous' Serial Killers: What Changed?

This question is highly engaging for true crime enthusiasts and sociologists alike. It addresses a perceived shift in the cultural landscape around serial killers. Reasons for this could include: improved forensics and law enforcement (DNA technology, inter-agency cooperation), changes in media policy (less sensationalism to avoid glorifying violence), and potentially a changing nature of crime (different types of violence or more discreet operations). It's a question that sparks debate about crime, media, and societal evolution.
