A Pennsylvania woman is still missing days after she vanished under suspicious circumstances.

Philadelphia police said Kaia Scott, 23, left early from her overnight job at a nursing home. Her family last saw her when she left for work on Saturday, and police said her car was found in the parking lot at her job, according to WCAU.

Philadelphia Police Captain John Craig said that Scott told her family about someone harassing her over the phone shortly before she vanished. Police said they are unsure who the caller was, but they are investigating.

Scott’s phone and social media have been inactive since her disappearance, according to WPVI.

Craig said Scott does not have a history of disappearing, and her co-workers did not notice anything out of the ordinary before she vanished.

“You have a 23-year-old young lady who has completely disappeared. She has not reached out to family or friends,” Craig said on Wednesday.

Police are reviewing surveillance footage from the area in hopes of discovering Scott’s whereabouts.

Scott was described as standing 5 feet, 6 inches tall and weighing about 120 pounds. Anyone with information concerning this case should call Philadelphia police at 215-686-3353.
