SAN DIEGO, Oct. 19 — Sandra Good, a follower of convicted mass murderer Charles Manson, has been moved to a federal women’s prison at Alderson, W.Va., where two other Manson disciples are imprisoned.

Miss Good will join Susan Murphy and Lynette “Squeaky” Fromme at Alderson. Miss Good and Miss Murphy were convicted of conspiring to send death threats to businessmen and government leaders, Miss Fromme is serving a life term for attempting to assassinate former President Gerald Ford in Sacramento.

Miss Good is serving a 15-year sentence and will be eligible for parole in 1981. Miss Murphy was sentenced to five years and becomes eligible for parole in December.

Manson is serving a life sentence in a California state prison for the brutal slayings of actress Sharon Tate and six others.

Also imprisoned at Alderson is Sara Jane Moore, who also was convicted of attempting to kill Ford.
