LOS ANGELES - A federal grand jury on Thursday indicted a Missouri woman for her alleged role in perpetrating a hoax on the online social network MySpace against a 13-year-old neighbor who committed suicide.

Lori Drew of suburban St. Louis allegedly helped create a false-identity MySpace account to contact Megan Meier, who thought she was chatting with a 16-year-old boy named Josh Evans. Josh didn't exist.

Megan hanged herself at home in October 2006 after receiving cruel messages, including one stating the world would be better off without her.

Salvador Hernandez, assistant agent in charge of the Los Angeles FBI office, called the case heart-rending.

"The Internet is a world unto itself. People must know how far they can go before they must stop. They exploited a young girl's weaknesses," Hernandez said. "Whether the defendant could have foreseen the results, she's responsible for her actions."

She's denied sending messages
Drew was charged with one count of conspiracy and three counts of accessing protected computers without authorization to get information used to inflict emotional distress on the girl.

Drew has denied creating the account or sending messages to Megan.

U.S. Attorney Thomas P. O'Brien said this was the first time the federal statute on accessing protected computers has been used in a social-networking case. It has been used in the past to address hacking.

"This was a tragedy that did not have to happen," O'Brien said.

Both the girl and MySpace are named as victims in the case, he said.

MySpace is a subsidiary of Beverly Hills-based Fox Interactive Media Inc., which is owned by News Corp. The indictment noted that MySpace computer servers are located in Los Angeles County.

Due to juvenile privacy rules, the U.S. attorney's office said, the indictment refers to the girl as M.T.M.

FBI agents in St. Louis and Los Angeles investigated the case, Hernandez said.
