The difference in names on the charging docs is puzzling.
It's probably just an error. The FBI agent's affidavit spells the name as Hunter. The agent probably was completely unaware of the alleged perp's connection to the Hunton family--or even who the Hunton family is--and just made a mistake. Charging documents just copied the affidavit.
I can't believe she used her regular cell phone to send the texts and photos and gave her real name to the site owner. I also can't believe that her Facebook page is still up.
BTW, Big Brothers/Big Sisters says she worked as an event co-ordinator and never had contact with kids.
