New criminal charges have been filed against a former Weyauwega man, for allegedly assaulting a horse in Manitowoc County. 53 year old Sterling Rachwal is due in court on Monday to answer to two misdemeanor counts of mistreatment of an animal. Authorities allege they used a g-p-s tracking device to follow Rachwal to a barn near the Manitowoc and Brown County line. There they set up a trail camera, and allegedly captured an image of him assaulting the horse. Rachwal is also currently facing similar charges in Brown County. He served nearly 19 years in a mental health facility after a similar case in Waupaca County in the mid-1990’s.
