Chicago police say Ashley Keller was located Wednesday.
Warminster Police say Keller, 21, was last seen on July 4th around 12:00 p.m. in Warminster.
Investigators say she was with 21-year-old Romulo Perez-Catalan, also known as Rony, who had several active warrants for his arrest.
Perez-Catalan had been arrested previously for assaulting Keller. He reportedly was released from prison in April and failed to show up for a court appearance last week on a burglary charge.
Perez-Catalan was also found and has been taken into police custody.
He is expected to be extradited to Pennsylvania.
