Yes, the mummy man was finally buried.

Cecil’s column today, about the mummified body found in a Long Beach amusement park, didn’t include details on what happened to the corpse after the discovery.

According to wikipedia, he was finally buried in the Boot Hill section of the Summit View Cemetery in Guthrie, Oklahoma on April 22, 1977. The state medical examiner ordered that two cubic yards of concrete was to be poured over McCurdy’s casket, so that his remains would never be disturbed again.

Wiki being wiki, some scepticism may be warranted. It looks like they have pretty good references, though. The Straight Dope column is one of them.

In 1978, DC borrowed this theme with some modification for the post-death history of its western bounty hunter character, Jonah Hex (scroll down).

If I recall the original news story…

Apparently with all his moving about, the true nature of McCurdy’s remains got lost. The Long Beach park thought they had a wax dummy that decorated their “house of Horrors”… then one day like in a bad horror movie, they were moving some stuff around, someone grabbed McCurdy and his arm came off - revealling meat and bones instead of 2x4’s and stuffing.

Thus giving some lucky workers a story that can’t be topped, that they’ll tell for the next 80 years.

I like how Wikipedia says the mummy was rediscovered, during filming of an episode for The Six Million Dollar Man:

“During filming of the 1977 episode ‘Carnival of Spies’ for the television show The Six Million Dollar Man, which was shot at the Pike in December 1976, a crew member was moving what was thought to be a wax mannequin that was hanging from a gallows. When the mannequin’s arm broke off, it was discovered that it was in fact the embalmed and mummified remains of a human. Later, when medical examiner Thomas Noguchi opened the mummy’s mouth for other clues, he was surprised to find a 1924 penny and a ticket from Sonney Amusement’s Museum of Crime in Los Angeles. That ticket and archived newspaper accounts helped police and researchers identify the body as that of Elmer McCurdy.”
