Ok, under AL law, harassing communications is defined as:.
(b)(1) HARASSING COMMUNICATIONS. A person commits the crime of harassing communications if, with intent to harass or alarm another person, he or she does any of the following:
a. Communicates with a person, anonymously or otherwise, by telephone, telegraph, mail, or any other form of written or electronic communication, in a manner likely to harass or cause alarm.
b. Makes a telephone call, whether or not a conversation ensues, with no purpose of legitimate communication.
c. Telephones another person and addresses to or about such other person any lewd or obscene words or language.
Nothing in this section shall apply to legitimate business telephone communications.
(2) Harassing communications is a Class C misdemeanor.
So as you can see, there has to be some direct communication between daughter and the other girl. Here there is none so I don't see the DA being able to find legal grounds to charge daughter with anything since she never directly contacted the other girl. This was just a private conversation between the other girls that apparently made its way to the girl who filed the complaint.
