The report said the horse's lack of muscle and body fat exposed its skeleton beneath its skin.
A veterinarian who was called to the home determined that the horse's weakness and inability to stand were because of starvation, and she recommended that it be euthanized, the report said.
Investigators said Brower owned another horse that was unable to stand or walk because it was emaciated. They said its skeleton was also visible beneath its skin.
The horse was taken to the Lake County Animal Shelter to be treated, the report said.
Brower was booked into the Lake County Jail on charges of animal cruelty.
