LOS ANGELES – An attorney representing a Missouri woman charged in connection with an Internet hoax that allegedly led a 13-year-old girl to commit suicide filed motions Wednesday seeking dismissal of the case.

Attorney H. Dean Steward filed three dismissal motions in U.S. District Court on behalf of defendant Lori Drew of the St. Louis suburb of O'Fallon.

Drew has pleaded not guilty to conspiracy and accessing computers without authorization.

Drew allegedly helped create a false-identity MySpace account that was used to convince neighbor girl Megan Meier she was chatting with a 16-year-old boy. Meier hanged herself at home in 2006, allegedly after receiving cruel messages.

The motions claim the indictment against Drew violates constitutional due process, fails to state an offense as required by federal rules of criminal procedure and alleges no crime but is instead vague.

U.S. attorney's spokesman Thom Mrozek declined comment and said a written government response to the motions is due in three weeks.

Drew's trial has been postponed from July 29 to Oct. 7. A motions hearing is set for Sept. 4.
