A federal judge in Los Angeles could decide today whether to allow use of an untested legal theory to prosecute a Westplex woman accused of helping to cyber-bully a local area teen who killed herself.

The pre-trial hearing is a chance for Lori Drew's defense lawyers to try to stop the case short of trial.  

Prosecutors say Drew and others plotted to humiliate 13 year old Megan Meier by using a faked teenage boy's identity on the social networking site MySpace. The U.S. attorney’s office says the plan was so effective that the girl committed suicide.  

St. Charles County and St. Louis federal prosecutors studied the case and decided no criminal charges applied. But federal prosecutors in Los Angeles, the area where the MySpace is based, obtained an indictment in May under the Computer Fraud and Abuse Act, which has previously been used against computer hackers. It charges Lori Drew with one count of conspiracy and three counts of illegally accessing protected computers.

U.S. District George Wu is scheduled to hear motions in the case at noon today.
