5-pound hunk of metal crashes into Mass. warehouse

The owners of a Plymouth, Mass., furniture warehouse want to know the origin of a chunk of metal that plunged through the roof.

No one was hurt when the six-inch, cylindrical piece of metal weighing about five pounds came through the roof Wednesday or Thursday. The chunk punched a small hole in the warehouse roof over a storage closet and scattered ceiling-tile debris on the floor.

An FAA spokeswoman says the chunk likely came from a piece of heavy machinery, possibly a wood chipper. That still doesn't explain how it came crashing through the roof.

Police are also stumped.

The owner of Michael's Furniture Warehouse says someone could have been killed.
