Murray explained: "I felt sorry for Michael. Unlike the rest of us he couldn't walk down the street. He had to hide away, he had no freedom. He was sad beyond measure... a recluse.
"Michael Jackson carried a trove of trash. Not treasures, trash. When we were alone he confessed to much to me. I was the source that he used to let go all of his pain. He was miserably-minded about life. Both past and present.
"He would speak to me about everything. He would cry and cry, he carried burdens that he had for years and years."
