GRESHAM, Ore. (AP) - Fliers have been posted around the Oregon city of Gresham asking people in the Portland suburb to help watch for a woman who disappeared Tuesday under suspicious circumstances.

Whitney Heichel (HY'-kel) left home but failed to arrive at work at a Starbucks less than five minutes away.

The 21-year-old's car was found later that morning in a Wood Village parking lot with a window broken out.

Police say Heichel's ATM card was used at a Troutdale gas station. Searchers have been looking for clues at Larch Mountain and Dodge Park - remote forested places east of Gresham where they believe her SUV was driven.

Police say they've received a number of tips and they continue to investigate it as a missing person case.
