Wausau police have arrested two men for allegedly setting a storage building near a high school on fire.  Twenty-two-year-old William Ritchie and 19-year-old Jacob Kerswill are scheduled to make court appearances next week.  Both men are charged with arson for burning the building near Wausau East High School early Wednesday morning.  Surveillance video shows a fire breaking out shortly after 3:00 a-m.  Graffiti had been painted on the same building in recent days and police think the two crimes are connected.
