The fire began about 7 p.m. Saturday. Kris Nolan Brown, Goodwill executive director, said goods in the processing portion of the Goodwill store sustained smoke and water damage.
Grand Island fire officials remained busy cleaning up the damage well into the night and were investigating the cause.
However, Goodwill employee Valentina Mansfield said she believed the fire was caused by a light used to help unload a Goodwill semitrailer.
The trailer had been backed up to one of the loading Goodwill doors on the east side of the building, Mansfield said. The loading doors are lined with foam and plastic.
Mansfield said a light rolled back and forth to help workers see as they unload the trailer got too close to the foam, and it caught fire.
``I'm very grateful no one was hurt,'' Nolan Brown said.
