Without reading the girl her Miranda Rights, they search her bag and find 3 people's information, photos of taxes she did not take, some copies of forged birth certificates, social security card ( wither her signature on it) and name change court order ( with her signature on it ).

They caught her going to fax the documents over to another school in another state. She said that a boy she liked got her and told her to change the name on the degrees to hers and then to his.

She asks the agents if she is in trouble and they reply no but she is not sure
