Police nationwide are still searching for the missing 11-year-old who was allegedly abducted by her mother four days ago. But messages that appeared online Friday have family members hopeful.

Fort Worth police confirm they are investigating activity on Jessica Smith’s Facebook page.

A message posted at about 3 p.m. said, “Everyone I'm fine you all can stop worrying about me.Just stop trying to contact me. I'm just done. I'm done with everyone."

Later the message, "Noo!! Guys it's really me! Just remember I'm safe I'll be home soon.. And thanks for all the support! :)" was added to the page.

Police said they are trying to determine who posted the messages and who has access to the girl's account.

Jessica and her mother Kimberly Smith disappeared late Monday or early Tuesday from their home in north Fort Worth. That was after family members said Smith threatened to hurt Jessica on Monday night.
