The family of a missing Pennsylvania woman is desperately searching for answers nearly a week after she abruptly vanished.

According to PennLive, Aleksandra A. Reeves, of Middleton, left her job as a business analyst on Tuesday and has not been seen since that afternoon. It is not clear if she permanently resigned or just said she needed some time off. She reportedly said she was overwhelmed by increasing stress and could not focus from her job.

Reeves has not previously shown any signs of mental illness or emotional instability. The 37-year-old woman, who goes by the nickname “Ola,” is a Polish native and has reportedly been living in the U.S. for 15 years. She married her husband in 2003 and has been at the same job for ten years.

Her last known location was a at a gas station in Elizabethtown. She called relatives about an hour later, reportedly sounding very anxious and saying she may not see them again. Prior to her disappearance, Reeves had seemed panicked and had talked about returning to her native Poland. But she left her passport behind.

“We understand she was under a great deal of stress,” her brother-in-law Shane Reeves told PennLive. “We’re very concerned for her health and well-being.”

Reeves had not used a credit or debit card since her gas station stop on Tuesday, and her family told the newspaper that she has cash available to her. Her car is a red two-door Fiat 500 Abarth with a black Pennsylvania license plate DA 29K8.

She is 5 feet 5 inches tall, about 115 lbs. with blonde hair, blue eyes, and a Polish accent.
