Murray, who was convicted of involuntary manslaughter and served two years in prison for administering an overdose of propofol to the late King of Pop in June 2009, called 89-year-old Joe “one of the worst fathers to his children in history” in a video obtained by The Blast.
“The cruelty expressed by Michael that he experienced at the hand of his father…” Murray, 65, alleged, trailing off before adding, “The fact that he was chemically castrated to maintain his high-pitched voice is beyond words.”
Murray, as well as reps for the Jackson family, did not immediately respond to PEOPLE’s request for comment.
This is not the first time Murray has made allegations about Michael being “chemically castrated.”
The former cardiologist previously shared similar claims in his 2016 book,This Is It! The Secret Lives of Dr. Conrad Murray and Michael Jackson, accusing Joe of forcing Michael to get hormone injections at age 12 to cure his acne and prevent his voice from changing.
“I hope Joe Jackson finds redemption in hell,” Murray said in The Blast video, days after Joe died of pancreatic cancer on June 27.
“We want to thank you all for the support you have shown us as we grieve for the patriarch of our family. We mourn the loss of our father and celebrate the life of a man who sacrificed so much to give us the life and success we have today. Thank you for respecting our privacy during this time,” the Jackson family said in a statement.
In October 2013, Murray was released from jail two years into a four-year sentence after he was convicted in 2011. His license to practice medicine was also suspended in three states.
