St. Louis ? A collection of photographs, books and FBI files from The Elvis Is Alive Museum sold for $8,300 on eBay, and the 81-year-old proprietor of the roadside attraction hopes the bidder will carry on his theory that the King never died.

A man from Laurel, Miss., must make a $500 deposit by the end of the weekend or lose his right to claim the stuff, the museum owner’s son said Friday.

The collection includes a tape recording of what is said to be Elvis Presley’s voice made long after the date of his death and piles of documents that are said to be FBI files proving Presley’s involvement with federal authorities.

Bill Beeny, a Baptist minister who founded the quirky museum in 1990, said he sold his memorabilia because he wants to refocus his energy on serving the needy in Warren County and raising money for relief efforts in Darfur.
