The cause of the explosion that blew a large hole in the Andersen Farms grain elevator, South Sioux City, NE, two weeks ago is still unknown, but officials say residents can move back into their homes after the elevator was partly demolished Monday night, reports the Sioux City Journal.
The official state of emergency, which was declared May 30 by the City of South Sioux City, has not yet been lifted.
As far as the cause, the contractor, Terminal Solutions, is removing two pieces of the elevator that could point to a possible cause for the explosion, said South Sioux City Police Chief Ed Mahon.
