A Fond du lac man involved in a shootout with police last fall was back in court facing additional charges. Shannon Rogler pleaded not guilty at an arraignment hearing Tuesday in Fond du Lac County Circuit Court to two additional charges of first degree recklessly endangering safety with use of a dangerous weapon. Rogler already faces multiple charges including attempted homicide, burglary, and arson. Police say Rogler set fire to a vacant house on North Hickory Street and then was involved in a standoff with police at the Elms Mobile Home park on South Main Street. Rogler fired multiple shots at officers at the scene, but nobody was injured. He surrendered after about five hours.
