Mummified body found inside wall of Oakland convention center

Construction workers discover body during renovation of the more than century old Henry J Kaiser Convention Center

The mysterious discovery of a mummified body in the walls of a historic convention center in Oakland, California, has prompted an urgent search for answers, as authorities seek to untangle the person's identity and how they came to be entombed within the building's walls.

Construction workers discovered the body on Wednesday afternoon during renovations of Henry J Kaiser Convention Center, a more-than-century old building near the city's downtown. Little is known about the person, who authorities said appears to be a man, or how he was preserved within the wall of the convention center, which has long been vacant. Officials estimate he had been there for between three and five years based on the state of decay.
