On August 9 , 1969 , the house was the site of the murders of Tate ( who was eight months pregnant at the time ) , coffee heiress Abigail Folger , hairdresser Jay Sebring , writer Wojciech Frykowski and Steven Parent by members of Manson 's " family " . Some authors and law enforcement personnel have theorized that the Cielo Drive house was targeted by Manson as revenge for Melcher 's rejection and that Manson was unaware that he and Bergen had moved out . However , family member Charles " Tex " Watson stated that Manson and company did , in fact , know that Melcher was no longer living there , and Terry 's former roommate , Mark Lindsay , stated : Everybody speculated that Manson sent his minions up there to get rid of Terry because he was angry about not getting a record deal . But Terry and I talked about it later and Terry said Manson knew ( Melcher had moved ) because Manson or someone from his organization left a note on Terry 's porch in Malibu . At that time , Melcher was producing singer Jimmy Boyd 's music for A&M Records . After initial tracks were recorded , the Manson murders took place , prompting Melcher to go into seclusion , and the session was never completed . When Manson was arrested , it was widely reported that he had sent his followers to the house to kill Melcher and Bergen . Manson family member Susan Atkins , who admitted her part in the murders , stated to police and before a grand jury that the house was chosen as the scene for the murders " to instill fear into Terry Melcher because Terry had given us his word on a few things and never came through with them " . Melcher took to employing a bodyguard and told Manson prosecutor Vincent Bugliosi that his fear was so great , he had been undergoing psychiatric treatment . Melcher was the most frightened of the witnesses at the trial , even though Bugliosi assured him that " Manson knew you were no longer living ( on Cielo Drive ) "
