She came to court to face theft charges and found officers waiting to arrest her for armed robbery.

Douglas County Sheriff’s investigators said they linked Patricia Ann Geyer to a early morning robbery at Harrah’s Lake Tahoe Saturday through her car and a photo identification by the victim. The 41-year-old South Lake Tahoe woman was already facing charges alleging that she took gaming tokens from her own table while working as a dealer at Bill’s Lake Tahoe Casino.

Sgt. Detective Tim Minister said around 6 a.m. Saturday, a woman was waiting in the valet parking area at Harrah’s when she was approached by a female who claimed she had a gun and demanded the woman hand over her purse. The robber held a gun-shaped object under her clothing.

Around the same time an Embassy Suites security guard noticed a vehicle with a towel covering the license plate illegally parked in the alleyway between Embassy Suites and Harrah’s. The guard told investigators that he took down the license plate, and a woman returned shortly later, apologized for parking there and drove away in the vehicle.

The license plate returned to Geyer, Minister said. Investigators put together a photographic lineup that was sent to the Las Vegas Police department for the woman to view. Geyer was fingered at the robber, Minister said.

Geyer was booked into the Douglas County Jail on a warrant for armed robbery and misdemeanor battery. Her bail is set at $100,000.

Minister said interviews with Geyer after her arrest led investigators to believe that she didn’t have a weapon at the time of the robbery.
