A horse was found slaughtered in Hialeah Gardens on Saturday.
Police believe the 15-year-old mare was killed for its meat on Thursday.
Richard Couto with Animal Rescue Mission said the owner has terminal cancer and that a caretaker is taking care of the ranch where the horse was kept.
The carcass was found in an area known for illegal slaughter farms, and where rescuers have found starving animals in the past.
