Amanda Marie Koller had moved back to the Pittsburgh area from Orlando, FL, in May 2011.
The 23-year-old did not establish or maintain a permanent address in the few short weeks after her return, according to her mother. On Sunday, June 12, 2011, she was stopped by Pittsburgh police and cited for operating a vehicle without a valid inspection and also without an emissions inspection.
Her car, a purple 2005 Scion TC, has a Pennsylvania license plate and also one from Florida, both of which expired in 2011. The license numbers are Pennsylvania GLH 0116 and Florida ANA 4580, according to the Pennsylvania Missing Persons website.
Following the police stop, Koller has not been seen nor heard from since.
She is described as 5-feet to 5-foot-5 and as about 100 to 150 pounds with brown hair and brown eyes. She has pierced ears and has tattoos—a sword and wings on her chest below the neckline, and vines on both legs.
Authorities don't have a description of what clothing Koller was wearing at the time of her disappearance. However, they noted that she might have substance abuse problems.
