Melinda Merck is the nation's leading forensic veterinarian.
She's at the University of Florida in Gainesville, where she's teaming with scientists in the human forensics lab to train others in investigating cases of animal abuse, neglect and hoarding.
Since last year, police officers, animal-cruelty investigators, veterinarians and others have come to Florida from around the world

Demand for forensic veterinarians has grown as many states have toughened their animal cruelty laws.
