(Tandin Chapman | Onaqui Catalogue Foundation) These two stallions, part of Utah’s Onaqui wild horse herd, were illegally killed last week, likely shot from Simpson Springs Mountain Road in Tooele County. A $22,500 reward has been posted for information about the crime. The pinto was known as Jasper and the pair were known to be companions that roamed freely together before they were found dead March 19.
