Monroe County District Attorney Kevin D. Croninger announced today that on Jan. 24, a Monroe County jury convicted 46-year-old, Jonathan L. Ellenburg, of four charges, including two counts of repeated sexual assault of a child and two counts of first-degree sexual assault of a child (sexual contact or sexual intercourse with a person under the age of 13).

The convictions came after a 2-1/2-day jury trial. The charges against Ellenburg stem from conduct that occurred between September 2012 and April 2018, during which time Ellenburg repeatedly sexually assaulted three different victims. Ellenburg refused to be present during the proceedings and instead appeared via video from a cell at the Monroe County Jail each morning and advised the court that he (Ellenburg) would not be participating. 

After the trial, the jury deliberated for about 1 ½ hour before reaching their verdicts. 

Monroe County District Attorney Kevin Croninger said, “This was a difficult case. The victims in this case have been presented with extremely difficult circumstances in their lives; despite these circumstances, they demonstrated a tremendous amount of strength and courage by taking the stand and describing the deplorable acts Mr. Ellenburg committed against them. We are grateful for the careful attention the jury paid to this serious matter and for the verdicts they returned. The verdicts will hopefully give some level of relief to the three victims who Mr. Ellenburg repeatedly sexually assaulted.” 

The prosecution of the case was handled by Monroe County District Attorney Kevin Croninger, with support and assistance by the staff of the Monroe County District Attorney’s Office. 

The investigation of the case was led by Detective John Brose of the Monroe County Sheriff’s Office, with assistance the Village of Norwalk Police Department and Monroe County Human Services. Croninger praised the work of Detective Brose and all officers involved: “This was a difficult and emotional case. The investigation needed to be done in an effective but sensitive manner. Detective Brose demonstrated a tremendous amount of skill and empathy throughout his investigation, and without his highly professional and effective work, convictions would not have been possible.” 

Ellenburg is serving a prison sentence related to other crimes he committed previously. After conviction, he was returned to the Kettle Moraine Correctional Facility to await sentencing.
