It’s unclear if the death toll will rise as crews sift through the rubble of the International Nutrition plant.

Interim Omaha Fire Chief Bernie Kanger says the search is progressing slowly because the structure is unsafe.

Kanger said he doesn’t believe anyone remaining inside is alive.

But officials haven’t said how many people didn’t make it out.

Thirty-eight people were working. Officials say two died, 10 were hospitalized and seven were hurt but refused treatment. They have not said how many of the 19 others escaped.
