Rock and roll singer Elvis Presley died of a heart attack in August 1977 at his home in Graceland, US, but bizarre conspiracy theorists have often challenged official reports.
And now, ahead of the 42nd anniversary of his death on August 16, another bizarre claim has resurfaced
Fox News reporter Suzanne Stratford headed an investigation into the conspiracy in 2002.
She spoke to Dr Donald Hinton, who claimed he treated the King after his “death” and even wrote a book about the cover-up with him.
“Elvis” penned the book under the name of his brother Jesse, who died at childbirth.
And – to make the theory all the more bonkers – “Elvis” supposedly left a voicemail for Suzanne.
The message, which sounded like it had been masked to reveal the person’s real identity, said: “Suzanna, the stories about me are not being told so seriously.
“I wish I could talk to you face to face.
“What can you do to allow me to see you face to face without any other reporters around?
“What can you do to guarantee my safety? I want to set the record straight.”
Perhaps unsurprisingly, “Elvis'” want to meet up with the reporter never materialised.
Suzanne added: “We agreed to travel anywhere in the world to meet with Jesse so he could substantiate these extraordinary claims.
“It hasn’t happened yet, he said the people paid to take care of him haven’t let him come out.”
During the investigation, Dr Hinton revealed how he “would never treat anyone before seeing them eye-to-eye and it is truly Elvis Aaron Presley”.
“There’s absolutely no doubt,” he continued.
“He said ‘doc, I was very ill. There were a lot of things going on and I felt that if I didn’t escape I would literally be dead within the year’.”
