Investigators say they may have found a car belonging to a Bucks County woman who disappeared three weeks ago in Philadelphia.

Cassandra Johnston, 26, was last seen at about 5:30 a.m. on July 10, when she left a friend’s home near Philadelphia’s Chinatown neighborhood, as CrimeOnline previously reported. Police reportedly found her phone near her friend’s home — but she had reportedly lost while out with her friend — and released surveillance footage of her car, a gray 2016 Ford Focus, approaching Interstate 95 about 6 a.m. that day.

Police found a car matching that description on Woodhaven Road in Northeast Philadelphia, several miles away from Chinatown, which is just north of City Center, Fox 29 reports.

Johnston, a student at Temple University, lives in Bucks County north of Philadelphia with her boyfriend and works at a day care facility there.

Police have not commented on whether they believe foul play is involved in Johnston’s disappearance. Johnston’s family has reportedly hired a private investigator to help search for her.
