If the owner of the equine cannot be found, if the owner refuses to enter into a consent order or to provide a written assurance that such equine will be given humane care and adequate food, water, shelter, and veterinary care, or if the owner fails to comply with this chapter after having entered into a consent order or having given a written assurance on a previous occasion, the Commissioner or his designated agent, the sheriff, any deputy sheriff, or any other law enforcement officer may dispose of the equine through sale at a public auction or by sealed bids or, if such equine is in a physical condition such that euthanasia is the only reasonable course of action, by humanely disposing of the equine. Prior to disposing of an equine through sale or euthanasia, the Commissioner or his designated agent, the sheriff, any deputy sheriff, or any other law enforcement officer shall make a reasonable effort to locate the owner and, if the owner cannot be located after reasonable effort, the sale or euthanasia may proceed. Any proceeds from the sale of such equine shall be used first to pay the costs of care given the equine and any funds remaining shall be paid into the state treasury if the equine was impounded by the Commissioner or his designated agent or into the county treasury if the equine was impounded by the sheriff, a deputy sheriff, or other law enforcement officer.
