Notorious cult leader and convicted murderer Charles Manson was too weak to receive emergency surgery Thursday night at a Bakersfield hospital, according to report from TMZ.

Doctors wanted to perform surgery on Manson when he first arrived at the hospital earlier this week, but he refused, TMZ reported Friday morning. He changed his mind, but doctors decided the procedure was too risky and canceled it, the report said.

Manson has been suffering from lower gastrointestinal bleeding caused by a lesion, a source told The Californian.

Manson, 82, was brought to Mercy Hospital downtown from Corcoran State Prison before dawn Monday morning with the ailment, according to a source with knowledge of the situation who spoke on condition of anonymity.

Hospital and California Department of Corrections and Rehabilitation officials have declined comment due to privacy laws. 

Manson orchestrated the killings of actress Sharon Tate, 8 1/2-months pregnant at the time, and four others at Tate' s home on Aug. 9, 1969. His followers then killed grocers Leno and Rosemary LaBianca the following night.

Manson, Leslie Van Houten, Patricia Krenwinkle, Susan Atkins and Charles Tex Watkins were each convicted of multiple counts of murder and sentenced to death. Those sentences were later changed to life terms in prison following a California Supreme Court ruling in 1972 that found the death penalty unconstitutional.

Atkins died in prison in 2009 at the age of 61 after suffering from cancer.

Manson has repeatedly been denied parole. His next hearing is scheduled for 2027.
