Ashley Keller, 21, was last seen on July 4 around 12 p.m. in Warminster. Investigators say she may be with 21-year-old Romulo Perez-Catalan, aka Rony, who has several active warrants for his arrest.
Keller has been listed as missing and endangered, Warminster police said. The two may be in an older, blue, two-door vehicle with a dent on the passenger door, rust around the rear bumper on the passenger side and a back seat filled with items.
Keller is described as 5'1", weighing 130 pounds, with brown hair and blue eyes. She has a tattoo of a hummingbird with a flower on her right foot.
Anyone with information is asked to call the Warminster Township Police Department at 215-672-1000, your local police department or 911.
Perez-Catalan has 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.
