Manson was reportedly taken from Corcoran State Prison in California, where he had been serving a life sentence, to a hospital in Bakersfield last week, TMZ and The Los Angeles Times reported at the time.
Manson was hospitalized for gastrointestinal issues at Bakersfield Hospital in January 2017.
The man who would become synonymous with pure evil was in his mid-30s in 1969, when he was charged with orchestrating a series of gruesome murders. He was the leader of the so-called Manson Family, a quasi-commune. He told followers an apocalyptic race war was coming.
