Prosecutors say they will not appeal the dismissal of a woman's convictions in a MySpace hoax directed at a 13-year-old girl who committed suicide.
Friday's announcement effectively ends the case against Lori Drew.
Federal Judge George Wu threw out Drew's conviction on three misdemeanor counts of accessing computers without authorization in July, citing the vagueness of the law.
Prosecutors had said the 50-year-old Drew sought to humiliate Megan Meier by helping create a fake teen boy who sent flirtatious messages on MySpace. The "boy" then dumped Megan and she hanged herself a short time later, in October 2006, in a St. Louis suburb.
Drew was not directly charged with causing Megan's death, but prosecutors tried to link her to the suicide through the computer fraud act.
