If she has been formally charged, and she has not bonded, then she would remain n custody. As far as a PD...has she applied? If so, the Public Defenders office will get to it. Remember, you get what you pay for. If you hire an experienced criminal defense attorney, they would have seen her weeks ago, and she would most likely be kept in the loop.
Typically, she would have been assigned a Public Defender attorney at first arraignment. With three other people being arrested for the same charge, however, the PDO will only be able to keep one of the cases and conflict out of the other three. Plus, you run into the issue of whether or not the case has been filed by the state attorney by now, leading to a question of whether or not she should be ROR'd for failure to file charges during the time frame. You really should just start calling attorneys in that area (you can find many fine attorneys on this site). The sooner things are looked into, the better chances she has.
