On conspiracy charges. Conspiracy to do what, is my question.

A Missouri mom was indicted Thursday for her alleged role in the death of a teen who killed herself over a failed Internet romance that turned out to be a hoax.
A federal indictment accuses Lori Drew, 49, of O’Fallon, Missouri, of using the social networking Web site MySpace.com to pose as a 16-year-old boy and feign romantic interest in the girl.
The girl, Megan Meier, committed suicide after her online love interest spurned her, according to prosecutors, telling her the world would be a better place without her.
Drew faces up to 20 years in prison on charges of conspiracy and accessing protected computers to obtain information to inflict emotional distress.
