Phil Spector's daughter has written a harrowing account of visiting her father in prison, detailing the "dismal" conditions and her fears the incarcerated music mogul is wasting away behind bars. The 73-year-old producer is serving 19 years-to-life in jail for the murder of actress Lana Clarkson in 2003 and he is being housed at the California State Prison, Corcoran in Coalinga, California. Spector's daughter, Nicole, has now revealed she dreads her visits to the medium-security facility as she hates seeing her father in such a bad way. In a piece for Britain's The Times, she writes, "I know there aren't enough blankets in prison. I know there's no heat... My father... didn't kill anyone. Neither of us is supposed to be here... Each time I see him, he looks thinner, wispier. I'm scared he'll disappear." The 30 year old admits she stocks up on junk food from the prison's vending machines for her dad to make sure he is getting enough to eat: "As soon as I get into the actual visiting centre, I rush to the vending machines to select meals for my dad. I usually blow the whole $50 we're allowed to bring in then and there. It's a wonderful feeling watching all that food drop down, knowing it will go into my father's body, nourishing him. And I'm excited to eat with him, no matter how dismal the environment, no matter how grim the mood... These times with him are one of the closest things I have left to what it was like with him at home." Nicole also reveals she now goes months without visiting her father after suffering a panic attack during her last trip to the prison. She adds, "The last time I visited was nine months ago, a fact that makes me feel anxious and ashamed. I feel I should be there every weekend."
