Norton Shores Police and the Maranatha Association say the reward to find out the person or persons responsible for an arson fire has doubled. The fire was in September in one of the residences at the Maranatha Bible and Missionary Conference site near Mona Lake in Norton Shores. The initial reward was $5,000, but today they announced they're raising it to $10,000 for information that leads to the arrest and conviction of those responsible for the blaze.
