*UPDATE - Emily Miller returned home by taxi around 12 a.m. Authorities are still investigating the case to find out where she was and who she was with.

 -------------------------------------

Authorities are looking for a 14-year-old female whose parents believe may be the victim of an online predator.

Emily Miller, 14, was last seen around 8 p.m. Saturday night at her home. The teen suffers from autism, bipolar disorder and ADHD. Reports of neighborhood dogs barking around 1 a.m. could mean she left around that time.

Emily is 5-foot-five and weighs 120 pounds. She has light red hair and blue eyes, wears glasses and has braces with blue rubber bands. She was last seen wearing blue jeans and a white tank top with a black shirt over it.

According to Newton County Sheriff's Office Lt. Tyrone Oliver, Emily was active on social networking sites and they are looking into the possibility that she is with someone she met online.
