A California review board denied parole Thursday to Charles "Tex" Watson, the self-described right-hand man of Charles Manson and a key figure in the Manson family's 1969 killing spree in the Los Angeles area, reports the Los Angeles Times .
Watson, 70, was initially sentenced to die in San Quentin's gas chamber for his part in the murder of pregnant actress Sharon Tate and six others. In 1973, his sentence was commuted to life in prison after the state Supreme Court ruled that the death penalty was unconstitutional.
