At least two women who worked at the plant died and at least three are missing. Employees allege they weren't allowed to leave as floodwaters rose.

The Tennessee Bureau of Investigation is looking into claims denied by Impact Plastics that managers did not let workers leave. Six were swept away.

Surviving employees alleged Impact Plastics told them to be at work and released them too late to escape floodwaters; the company has said it did not threaten to fire anyone.
