The 10 horses found dead in a field in Magna likely died of thirst or hunger, according to a preliminary examination by the Utah State Veterinarian's Office.
The horses were found in a private, fenced off field near Pleasant Green Cemetery, around 3500 S. 9200 West. Police and witnesses said the horses appeared to have died of thirst, but the official cause of death will not be known until the state veterinarian's office completes necropsies of the animals.
Seven of the ten horses were too decomposed to be examined, but the three looked at by the State Veterinary Diagnostic Lab at Utah State University showed signs of dehydration and malnutrition. The bodies of the three horses were sent to another lab, where necropsies will be performed to confirm those initial suspicions, said Larry Lewis, a spokesman for the Utah Dept. of Agriculture and Food.
