The creator of phony profile on MySpace whose cruel messages may have led to the suicide of a 13-year-old suburban St. Louis girl has spoken out for the first time, admitting she created the site with the active participation of the mother of one of the dead teen's friends.

Megan Meier, of Dardenne Prairie, Mo., hanged herself on Oct. 16, 2006, after being dumped by "Josh," a fictitious boy created by Ashley Grills, an employee of Lori Drew, the mother of one of Megan's friends.

"We were just combining ideas about how we can figure out what Megan was saying about Lori's daughter," Grills told ABC. "It was all three of us — me and Lori and her daughter."

Grills spoke to ABC's "Good Morning America" on Tuesday, telling the network that she wrote the words "the world would be a better place without you" that may have driven Meier to take her own life.

"I was trying to get her angry so she would leave him alone and I could get rid of the whole MySpace," Grills said.

Drew and her attorney deny the allegations that the mother was involved with the hoax Web profile.

Prosecutors declined to charge anyone in the case, in part because no specific laws appeared to apply. But some communities, including Megan's hometown, have adopted, or are considering adopting, laws to go after those involved in Internet bullying.
