My question involves criminal law for the state of: Indiana
My mother and brothers boyfriend got into a verbal fighting match via text messages and phone calls. The girlfriend verbal threatened to do harm to my mother and used a social network site to call her name, and continue to threaten. That same evening while my mom was shopping in a store the girlfriend found her (which she threatened to do) assaulted my mom in the store. She was bumping my mother with her shoulder repeatedly, grabbed my mothers wrist and pulled the phone out of my mothers hand. My mom was trying to call the police b/c she asked the cashiers to do it they both refused. The girlfriend has her mom, dad, sister, 2 or 3 friends, a cousin and her young (under 10) son there. The cops did not arrest claiming is was domestic dispute. My mother has asked for police reports and no one can give her one. They tell her she needs to present it to the prosecutor, but the prosecutor has been leaving early and she is unable to do it until after the weekend. Meanwhile this girl had a restraining order put on my mom claiming that my mom is harassing and stalking her. When my mom tried to get a restraining order the judge has went home. Also, this girl continues to threaten my mom on the social network and has included numerous of her friends to do the same. The girl is also frequently visiting the place my dad works and other places my sisters and brothers go. She is from the next town about 20-30 miles away. I'd like to know what we can do about this to make sure it doesn't get lost b/c someone told my mom the cop that was there said he was not going to investigate? The store has video but the video does not show their faces so they said they can't use it. If the cops don't do anything where else can my mom go? this is a very small town. Thanks for any advice
