A construction crew found a mummified body in the wall of a convention center in Oakland, Calif., on Wednesday, authorities said.
A worker found the body around 1 p.m. in a wall being deconstructed during renovations at the Henry J. Kaiser Convention Center, according to the Alameda County Sheriff’s Office.
“We have found remains best described as mummified,” Lt. Ray Kelly told NBC News. “The conditions within the walls were such that the body was kept in good condition.”
Authorities said the mummified body was in an advanced stage of decomposition and had likely been there for “several years”.
“Any theory is possible,” Kelly added, according to NBC News. “It could be anything from someone who got in behind the wall and got trapped and died to someone who put the person there. God only knows.”
The decomposition of the body made it impossible to immediately determine the person’s age or sex, the sheriff’s office said.
Authorities are conducting further forensic testing, Oakland Police Department spokesman Kim Armstead told Mercury News.
The convention center opened in 1915 but has been closed since 2005, the newspaper reported.
However, in 2015 the city council struck a deal with a developer to lease the building and turn it into a commercial and performing arts space.
