A woman without a gun should not have been sent to investigate killer dogs.
Exactly.
A dog, even a domesticated dog is still a wild animal with millions of years of instinct hard wired into it and it's behavior is always unpredictable and in the case of a dog you're dealing with one of the most powerful,ruthless and efficient predators on Earth. Any dog at 30+ pounds and an unarmed human, especially a female and you're all but dead. Two or more and you are dead. May God have mercy of the poor young woman. What a tragedy.
