How can the neighborhood evict the neighbor?

It has been almost 2 months since this woman (around 40) has moved in with her family. Since she has been here there has been loud music daily, loud talking, a shooting on lawn from an out of control party, numerous fights, and threats to the other neighbors because they called the cops. One of my neighbors actually bought a shotgun just to protect himself because he was threatened by her company...The police have been over here numerous times and they act like they don't give a crap. We just want our peaceful, quiet, and cop free neighborhood back...
