SOUTH SIOUX CITY, Neb. (AP) — Residents can return to their homes near a northeast Nebraska grain elevator that was heavily damaged by an explosion. Terminal Solutions, which is based in Radcliffe, Iowa, on Monday was able to tear down the top of the main tower, which officials say posed the danger of uncontrolled collapse. The remaining portion is considered safe for subsequent razing by a wrecking ball.

The blast on May 29 blew a gaping hole into the Andersen Farms elevator and injured a worker. Residents of 26 houses nearby were evacuated. The cause of the explosion remains under investigation.
