A North Dakota man who pleaded guilty to maltreating more than 100 horses last year has been arrested on charges that he violated terms of his probation.

In 2013, the Morton County, North Dakota, Sheriff's Department seized more than 120 horses without access to food or water residing on a property near Salem; the carcasses of another 96 horses were found on the same property. Further, another 38 horses in Burleigh County, North Dakota, were seized by law enforcement personnel there.

The animals' owner William Kiefer was subsequently charged in Morton County with five counts of overworking, mistreating, or abandoning an animal; he faced four counts of similar charges in Burleigh County.

In December 2013, during an appearance in Morton County District Court, Kiefer pleaded guilty to the charges against him. Court documents indicate that Kiefer was sentenced to one year in jail with all but six months of that sentence suspended. He was also sentenced to serve two years' probation during which time he was forbidden from owning any animals
