GRAND RAPIDS (WKZO) -- The FBI is heading up the investigation into where a suspicious package came from that was delivered to Grand Rapids-based Bible publisher Zondervan Corporation.  It was opened in the mail room Tuesday, and a powder fell out of a hollowed-out part of a magazine.

Police said there was a message written on some papers in the package, but will not say what it said.  The powdery substance wasn't harmful, and no one was hurt.
