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

The Tennessee Bureau of Investigation, the state’s criminal investigation agency, said Wednesday it is looking into allegations against an Erwin plastics factory where several workers died and some went missing after they were swept away by floodwaters from Hurricane Helene.

“At the request of 1st Judicial District Attorney General Steve Finney, TBI agents are investigating allegations involving Impact Plastics,” Leslie Earhart, the bureau’s spokesperson, said in a statement to NBC News. The bureau deferred additional questions to the District Attorney General’s Office.

Finney in a statement said that he specifically asked “that they review the occurrences of Friday, September 27, 2024, to identify any potential criminal violations.”
