A man who exposed himself to an 11 year old girl in the Waverly Wal-Mart has been sentenced to prison time, according to the Waterloo Cedar Falls Courier. 37 year old Anthony Knudsen was sentenced to up to two years in prison after pleading guilty to one count of indecent exposure. He was already on parole after being convicted of lascivious acts with a child in Butler County in 2005. He was sentenced to prison time in that case as well. He was released in 2011 but was placed on lifetime parole.
