Oregon police are investigating a missing persons case involving a 21-year-old woman named Whitney Heichel.

Heichel last seen by her husband at 6:45 a.m. on Tuesday at her Gresham, Ore., apartment before leaving for her shift at Starbucks about five minutes away from her home, police said in a statement obtained by MSN.

When Heichel dialed to show up for her shift at the local Starbucks, co-workers phoned her husband, Clint Heichel in an effort to find out if she was home sick. He he called 911 to report her missing just before 10 a.m.

A team of 24 detectives were following leads and canvassing areas Wednesday where police believe Heichel may have been immediately prior to her disappearance.

Police say that several transaction were made on Heichel’s debit card the morning she went missing, including once at a gas station at 9:14 a.m. and again at ATM machines and other gas stations at 9:22 a.m. and 9:30 a.m.

According to a report done by MSN, which cites a missing person flyer, a gas station attendant at one of the stations said he remembered seeing her SUV and said Heichel was sitting in the passenger seat with a man driving. The man reportedly bought a small amount of gas.

Authorities have since discovered Heichel’s vehicle, a black 1999 Ford Explorer with tinted taillights and an Oregon license plate in a Wal-mart parking lot in Wood Village, Ore., about three miles north of Gresham. The vehicle had a shattered window and it appeared as if someone had rummaged around inside, police said.

Heichel is 5'2'' tall and weighs 120 pounds. Police tell reporters they are treating the incident as a suspicious missing person’s case.
