Elvis lives and still sings, but he no longer shakes his hips because he is old now and has arthritis, Dr. Donald Hinton said.
"I hear from him on a regular basis. ... On Sunday, it was by phone," Hinton said. "I'm treating Elvis Aaron Presley, the entertainer, (whom) everybody believes died in 1977."
A photo (left) in a book by Hinton supposedly shows a present-day Elvis, who has had plastic surgery.
"He has white hair now. He's 67 years old," Hinton said. "He's given me things that can be tested (and) that actually (have) his DNA on them."
Hinton said he has a gold tooth from Elvis. He said he also co-wrote a book about the King with Elvis called "The Truth About Elvis Aron Presley."
Elvis now goes by Jessie, the name of his twin brother, who died at birth, Hinton said.
Hinton speaks to groups about his once-secret patient and about the book that explains how friends helped Elvis hide.
"This is all part of his plan for 2002," Hinton said.
Elvis has a plan to bring grieving fans out of the dark and tell them he faked his death 25 years ago so that he could get away and get healthy, Hinton said.
"People will think I'm crazy or that I've been tricked by someone," Hinton said.
Hinton holds a medical degree from the University of Kansas. He is a board-certified practicing physician.
Missouri's Board of Healing Arts told KMBC-TV that Hinton is "currently licensed as an MD." His license was issued in 1993, according to the board. "It is current (and) active with no discipline," the board said of Hinton's license.
Hinton said people have made a lot of money from Elvis' supposed death.
The publisher for Hinton's book said it has not made a profit, and Hinton supposedly told his publisher that he didn't want any money from the book.
The book cost thousands of dollars to publish, and Hinton said the money came out of his pocket.
