The last time the user logged on was Oct. 8, the day before Zahra was reported missing. In the "Details" section of the page, the user wrote that she's a "proud parent." Under "Mood," she wrote "crazy." One picture of Zahra was captioned "The Dark Child!!! lol."
After she was arrested, Elisa Baker penned several jailhouse letters to crime memorabilia dealer Eric Gein. In one letter she wrote that she and Adam Baker did not kill Zahra, but said that what Adam Baker did afterwards was "kinda horrifying."
Adam Baker has denied any involvement in the girl's death and dismemberment.
Gein, who runs the website SerialKillersInk.net, told ABC News he contacted Elisa Baker by letter under an assumed name.
In three rambling pages of another letter exclusively obtained by ABC News in November, Elisa Baker never mentions Zahra or any concern for her stepdaughter, who was still a missing person when the letter was written on Oct. 29. She also doesn't cite any remorse for the girl's disappearance.
In the letter she said she "ain't the monster people are saying."
