CSI for animals: Forensic vets battle pet abuse, neglect

The American Society for the Prevention of Cruelty to Animals has three forensic veterinarians on staff dedicated to capturing evidence to punish animal abusers.

The New York-based vets have testified in some of the first animal cruelty cases to use DNA at trial to obtain felony convictions.

A traveling ASPCA crew in January rescued some 600 animals from a no-kill shelter in North Carolina suspected of abuse and neglect.

The leader of the team, Dr. Robert Reisman, says his work in this field has shown there is often a connection between animal abuse and human violence. In many cases, when there's a human domestic violence victim, there's also an animal victim at the same time.
