DECATUR, Ga. -- Police outside Atlanta say a college student who took in abandoned animals was attacked and killed by a dog.

Authorities say Carey had five dogs living with her at the time of her death. They included a pit bull she had owned for six years. Other dogs included a boxer mix she had taken in and a Presa, a large Spanish breed. Authorities say she was also dogsitting another Presa for a friend.

The friend discovered her body Sunday afternoon after Carey failed to show up for work at Alpharetta's Loving Hands Animal Clinic.

DeKalb County police spokeswoman Mekka Parish says all of the dogs were euthanized Wednesday.
