Police said a man sexually abused a girl under the age of 12 when they both lived in Dubuque in 2019. 47-year-old Shannon Towne, of East Dubuque, Ill., was arrested at 4:45 p.m. Tuesday at Dubuque Law Enforcement Center on a warrant charging two counts of second-degree sexual abuse. Court documents state that a teenage girl approached authorities in Wisconsin in September 2022. The girl told police that she had been sexually abused on two occasions by Towne, a man she knew, approximately three years earlier.
