Any of those ring a bell? Saying no mass murderers were fame-seekers EXCEPT those who were is a tautology meaning nothing. Between terrorists trying to promote their twisted agendas and pariahs trying to "show" the rest of humanity they consider mortal foes, the hope of celebrity has driven MANY mass murderers. Look at people like the Zodiac and other serial killers who send letters to newspapers bragging of their crimes and taunting law enforcement as inferiors. Why did Mark David Chapman kill John Lennon? Because he thought it would impress Jody Foster, but how did he know she would even find out about it? Because it would put his name alongside Lennons in every headline.

Sadly, murdering a bunch of people almost guarantees getting ones name in the paper, which says as much about the rest of society as it does mass murderers. Entertainment networks broadcast fictional sex and violence because audiences demonstrably demand it, and many mass murderers commit shocking horrors precisely because they know it stirs morbid curiosity in "sane" members of society.
