[3][4] Good joined the Manson Family in April 1968 and a few months later went off with them when they moved to a new home at Spahn Ranch in the mountains west of Chatsworth.

She was in jail with Mary Brunner for attempting to use stolen credit cards when the Tate/La Bianca murders took place, but was back at the ranch in time to get arrested during the August 16 raid.

On September 10, 1975, in a subsequent interview with Barbara Frum of the CBC radio program As It Happens, Good made similar threats against persons to avenge the killing of trees.

[13] Good was paroled in early December 1985, and released from the Federal Correctional Center for Women in Alderson, West Virginia, after having served nearly 10 years of her 15-year sentence.

[16] Following her parole, Good moved to Hanford, California, near Corcoran State Prison, to be closer to Manson, although as a convicted felon she was not permitted to visit him.
