The man who attacked the Coast Guard Headquarters in Grand Haven Sunday morning has been identified as 34 year old Matt Krueger.  "West Michigan Politics" says he may be from Illinois, but that won't be known for certain until he is formally identified at arraignment in Ottawa County Court.  The arraignment will happen today or tomorrow.   Krueger is also a suspect in the arson fire of a barn early Sunday in Oceana County.  That barn was set on fire about two hours before police say he drove his truck through a fence at the Coast Guard station.
