Two weeks ago, Joe Jackson - the father of the Jackson Five - passed away at the age of 89. Following his death, the Jackson family had only positive things to say about the man, with Paris Jackson, his granddaughter, sharing a particularly emotion statement on Instagram. "You are the first true Jackson, the legend that started it all," she wrote. "None of us would be anywhere near where we’re at if it weren’t for you. You are the strongest man I know. Your life’s work will go down in history, as will you, to be known as one of the greatest patriarchs to ever live." However, not <a href="http://vt.co/news/entertainment-news/michael-jacksons-father-joe-jackson-dies-aged-89/">everybody who knew Joe had such warm sentiments</a> to share about the man. In fact, Conrad Murray - Michael Jackson's disgraced former physician - has said quite the opposite. "Joe Jackson was one of the worst fathers to his children in history," said Murray in a clip obtained by <a href="https://theblast.com/conrad-murray-michael-jackson-joe-jackson/">The Blast</a>.  The doctor then went on to say that Michael Jackson had confided in him about the abuse he had faced by his father; in particular, the "chemical castration" he was subjected to at a young age. He said: "The cruelty expressed by Michael that he experienced at the hand of his father, particularly the bad treatments and - moreover - the fact that he was chemically castrated to maintain his high-pitched voice is beyond words." This isn't the first time he has made such claims, either. Two years ago, in a self-published book titled, This Is It! The Secret Lives of Dr. Conrad Murray and Michael Jackson, the physician alleged that Joe Jackson had given hormone injections to his son from the age of 12 in order to prevent his voice from deepening, but also to cure his acne. "I knew and cared for Michael very well, and he told me of the immense suffering at the hands of his father. It was dreadful. Beyond imagination and words," Murray said. "I would not shed a single tear for the passing of this cruel and evil man, Joe Jackson. "It is said that only the good die young. I hope Joe Jackson finds redemption in hell." Murray and Joe had butted heads on several occasions before - most notably in 2010, when Jackson filed a wrongful death lawsuit against the doctor after Michael's untimely demise a year earlier. The case was ultimately dropped, however, even though Murray eventually went on to serve two years in prison for the involuntary manslaughter of the King of Pop. Michael Jackson himself was also not on good terms with his father before he died, and Joe was actually left out of his son's will at the time of his passing in 2009. However, we cannot be sure of why the two fell out, nor can we be certain at this moment that any of Murray's claims are true. Michael may have said those things to his doctor, of course, but - for now - they remain unsubstantiated, and so can be held as nothing more than speculation.
