GRAND ISLAND, Neb. (AP) – A 49-year-old Iowa woman on probation for dumping 23 dead or dying dogs in a Nebraska cornfield in 2008 has admitted violating probation by living with 13 dogs.  A judge told Denise Withee, of Mapleton, Iowa, on Thursday that she’ll be resentenced on April 26 and that she could face prison time. Court records say Withee originally was sentenced in September 2009 to four years of probation and was ordered not to own, possess or reside with any animal for five years. The 13 dogs were found by Iowa authorities in January in the home Withee shares with her mother. Withee will remain in Hall County Jail in Nebraska until her sentencing.
