What happened to sharon tate?
She and three friends, Abigail Folger, Wojciech Frykowski and Jay Sebring (and a young man visiting the guest house, Steven Parent) were not just murderedmbut slaughtered by followers of Charles Manson on his instructions. It was a random killing, Manson wanted to 'teach Hollywood a lesson' because he had failed to get a record deal.
It was probably one of the worst crimes in history. I'd advise you not to google image "the Manson murders" unless you like seeing pictures of people including a pregnant Sharon stabbed multiple times.
Manson didn't directly kill them but he was the leader of a cult and if not for him, Tex Watson, Pat Krenwinkel and Susan Atkins would never have gone up there to kill.
