Did not know that! Were the vics involved in the music industry?
They had the misfortune of living at the address where somebody involved with Manson had lived.
Manson sent his killers to the address, not knowing or caring who they murdered.
“Manson’s relationship with the entertainment industry and his obsession with fame were chronicled over 12 episodes of Karina Longworth’s Hollywood history podcast, You Must Remember This, in 2015. “Maybe more than anything else Charlie Manson’s story is a Hollywood story,” she told her listeners.
“Longworth said on her podcast that the killings could be seen “as the fulfilled revenge fantasy of one of the millions of pilgrims who have come to Hollywood looking to make their mark, only to be condescended and lied to and turned away with nothing to show for their efforts.”
