Manson was reportedly rushed to a hospital earlier in the week suffering from internal bleeding, but doctors have apparently been unable to stabilize his condition.
Manson was sentenced to death in 1971 after being convicted of first-degree murder and conspiracy to commit murder for the deaths of seven people at the hands of members of his followers. Most notable among Manson's victims was actress Sharon Tate. When the death penalty was ruled unconstitutional in California in 1972, Manson's sentence was reduced to life in prison.
