A former Weyauwega man convicted of molesting a horse nearly 20 years ago is being held in the Brown County jail on a 5000 dollar cash bond on allegations of abusing horses in Brown and Manitowoc Counties. 53 year old Sterling Rachwal appeared in Brown County Court Wednesday for a probable cause hearing. Authorities say they have video evidence of Rachwal assaulting a horse in a barn in Maribel last Saturday. Investigators say they suspected Rachwal in an earlier incident in Eaton, and obtained a warrant to place a G-P-S tracking device in his vehicle. It showed multiple trips to the Maribel barn. Formal charges have not yet been filed in the case. Rachwal served nearly 19 years in a mental health facility for a similar crime in Waupaca County in the mid 90’s.
