Justice for Sadie

Our dog Sadie has been missing for seven days. Today my wife and I went out looking for her as we have done everyday. We found her out befind our house on Our property shot with an arrow. The scum who did this walked onto our land and broke off as much of the arrow as they could. The police officer who came out said that it looked like she was just trying to get home. I want justice for my dog. She was taken from us way too soon by a heartless person I want to see pay for their crime. I am wanting to raise money for a reward. Any help will be appreciated. Thank you!
