Police have been searching areas near the 422 eastbound Interchange with 76 in King of Prussia.

They are hoping for any clue that will lead them to Deirdre Magolon.

The Royersford woman was last seen Friday night.

“As the days go on, you just don’t know and you just rack your brain and we just pray she’s safe,” said her sister Jamie Albert.

Magolon’s sister and mom tell CBS 3 Eyewitness News the 20-year-old took her sister’s black Mazda just before 7 p.m. Friday without permission.

The car stalled near the 422/76 interchange.

State police found it at 7:20 p.m.

There was no sign of Magolon.

“I have no idea what her plans were that night. I have no idea,” said her mother Beth Magolon.

CBS 3 Eyewitness News was there as the lead Upper Providence Township Police Detective searched the car Monday.

“The driver’s side door was unlocked and a purse or wallet with some currency was left inside the vehicle,” said Upper Providence Police Sergeant Raymond Bechtel.

Magolon describes her daughter as impulsive and a free spirit, saying she’s left home before, but never longer than a few hours.

They are concerned about what may have happened to her after the car broke down.

Magolon left her sister’s wallet in the car.

‘Anytime you have a youngster, especially female, that’s out and away from home, there’s a greater chance of them being victimized and that’s what we’re concerned about here,” said Sergeant Bechtel.

Magolon does not have her cell phone or any credit cards that her family is aware of.

“I think something, you know, interfered with her plans to return,” said her mother.
