If this were my dog and I caught the person who did it, they'd be dead.
As if it's not already bad enough, I read another article in the paper that said this girl has already suffered some trauma in the past and that this was her therapy dog.
I'm going to get in touch with the local chapter of the Humane Society and see if they'll accept donations to add to the reward.
Edit: OMG, it gets even worse. According to this article, the police were incompetent and cruel when they came to the family's house.
