DeWITT, Iowa — The Iowa State Fire Marshal is calling the cause of a Mother's Day fire in DeWitt as undetermined, but not suspicious.

Sandry said the home is destroyed.

The family, Jessie Smith and her two children, were not home at the time. The American Red Cross is assisting the family. Donations may be made by calling the Gateway Chapter of the Red Cross at 563-242-5223.
