The two developed a virtual friendship that lasted more than a month before things inexplicably took a downward turn. "Megan gets an e-mail, or a message from Josh on her MySpace Oct. 15, 2006, saying, 'I don't know if I want to be friends with you any longer because I hear you're not nice to your friends,'" Tina Meier said.
The next day, Ashley, posing as Josh, got into an argument with Megan online that ended with Josh saying that the world would be better off without Megan.
Megan hanged herself that day.
Ashley Grills, 19, said in an interview with "Good Morning America" that Lori Drew was involved in creating the account and wrote some of the messages to Meier.
"We were just combining ideas about how we can figure out what Megan was saying about Lori's daughter," Grills told ABC News' Deborah Roberts. "It was all three of us — me and Lori and her daughter."
