A 62-year-old Sleepy Eye man accused of making sexual advances to a police officer posing as a 15-year-old girl online was sentenced to 45 days in jail and 3 years of probation in Brown County Court Monday. Jon Robert Jahnke was also fined $1,500 after pleading guilty to 1 of 3 counts of electronic solicitation of a child. The other charges were dismissed in exchange for the plea. The incident occurred in January of 2010. A special agent with the Wisconsin Department of Justice working undercover in an online chat room was contacted by Jahnke, who then engaged “her” in a conversation that lasted several hours and involved offers to meet in person as well as descriptions of sexually explicit acts and sexual photos.
