Maybe this will help you out! I got this off of a rescue site here in TN.
What to Do About Animal Cruelty
Animal cruelty and neglect are crimes. If you are aware of animal cruelty or neglect, immediately contact the local police or sheriff, and follow up to make sure that your concerns are taken seriously and that the situation is investigated. Please do not ignore the problem or assume that "someone else will do something about it." Even if you visit an animal shelter and observe cruelty or neglect, don't hesitate to report it.
