8. In the summer of 1968, Krenwinkel and Ella Bailed managed to get picked up by the Beach Boys founding member and drummer, Dennis Wilson, who invited them to his home. Once they got word back to Manson about the mansion they were staying at, Manson brought the entire family there. After destroying much of the mansion, they left.

14. One week after the murders on August 16, 1969, Krenwinkel, Manson and other “family” members were rounded up by police and arrested on suspicion of auto theft. However, because of a date error, the search warrant was later ruled invalid and the group was released.
