When Tina Meier's 13-year-old daughter, Megan, committed suicide after being bullied on the internet, her grief was so encompassing she felt at times she couldn't breathe. But in recent months, the Missouri woman has focused on ways to protect other children from cyber bullying--even leaving her job as a real estate agent to dedicate herself to the Megan Meier Foundation.

"Megan is still my daughter, no matter what, and I am going out there and fighting for her still because she is still my daughter," Meier said.

A group of friends and relatives helped Meier create the foundation, which seeks to educate both children and adults and encourage positive changes to prevent bullying, both in person and online.

Meier and the volunteers are working to improve laws. They speak at schools and to parent groups. They hope to begin offering scholarships to children who help other children in some way.

Megan hanged herself in her closet on Oct. 16, 2006. Her tragic story became public last fall, following an article in a suburban St. Louis newspaper that prompted widespread interest in her case. (See "Studies suggest cyber bullying is on the rise.")

Megan had a history of attention deficit disorder and depression. Her suicide came soon after she received cruel messages through the social-networking web site MySpace.

Earlier this month, a federal grand jury indicted 49-year-old Lori Drew, a neighbor of Megan and her family. She is accused of one count of conspiracy and three counts of accessing protected computers without authorization to get information used to inflict emotional distress. (See "Woman indicted in MySpace suicide case.")

The charges were filed in California, where MySpace is based. MySpace is a subsidiary of Beverly Hills-based Fox Interactive Media Inc., which is owned by News Corp.

Authorities have said Drew, Drew's teenage daughter, and another teen took part in an online hoax, creating the fake identity of a boy named Josh Evans who befriended and flirted with Megan online. Drew allegedly wanted to know what Megan was saying about her own daughter online. Shortly before Megan's death, the comments from "Josh" and some other internet users turned cruel, with the faux boy allegedly saying the world would be better without Megan.

Drew's attorney, Dean Steward, said she has been advised by her lawyers not to speak about the case. Another lawyer for Drew previously said she did not create the account and was not aware of any mean messages sent to the girl before her death.

Meier, 37, said her grief hits her in waves, and it remains difficult to talk about Megan's death. Meier's life has gone through other changes as well. She and her husband, Ron, divorced. Meier now lives in a townhouse not far from her old neighborhood with her 12-year-old daughter, Allison.
