survived. He had physical effects for the rest of his life, including being required to wear a surgical corset. The shooting had a profound effect on Warhol's life and art. Solanas was arrested the day after the assault, after turning herself in to police. By way of explanation, she said that Warhol "had too much control over my life". She was subsequently diagnosed with paranoid schizophrenia and eventually sentenced to three years under the control of the Department of Corrections. After the shooting, the Factory scene heavily increased its security, and for many the "Factory 60s" ended ("The superstars from the old Factory days didn't come around to the new Factory much").
