CHARLES MANSON

Imprisoned in Corcoran, Calif.

Manson, who ordered the Tate-LaBianca killings but was not present for any of them, was found guilty of murder and sentenced to death.

After the California Supreme Court overturned capital punishment in 1972, Manson’s sentence was reduced to life in prison.

Manson, now 80, has had “hundreds” of rules violations, prison officials say, and has gotten in trouble for having a cellphone and prison-made weapon while incarcerated. Manson has been denied parole 12 times. His next parole hearing is scheduled for 2027, when he will be 92. He has been in prison since 1971, and is incarcerated in Corcoran.

In November, Manson and Afton Elaine Burton, a 27-year-old Manson devotee, were granted a marriage license, but it expired in February before the two could marry.
