If she truly has been sitting in jail for 6 months without having been brought before any court, her rights almost certainly have been violated.
Does she have an attorney representing her?
If she does not now have an attorney representing her, can her friends and relatives get an attorney for her?
If she is without money, she likely qualifies for representation by a public defender? Has anyone contacted the public defenders in her area to ask them to check on her?
