Ex-employee, boyfriend plead not guilty in Monroe Starbucks robbery

EVERETT — A former Starbucks employee and her boyfriend pleaded not guilty yesterday in Snohomish County Superior Court to first-degree robbery in a bizarre holdup last week at the Monroe outlet where she used to work.

Trina Della Petrycki, 24, and David Michael Williams II, 21, are being held in lieu of $100,000 cash bail at the Snohomish County Jail, accused of taking about $3,400 during an armed robbery of a Starbucks coffee shop on Highway 2 last Tuesday.

Monroe police said the robbers also made an employee help them operate the store's drive-up window for about half an hour and pocketed the cash.

According to charging papers, Petrycki, of Gold Bar, went into the Starbucks around 5 a.m. and starting chatting with one of the employees she knew. Williams, of Everett, came in, pulled a gun and forced the three workers into a back room, the papers say.

The hands of two clerks were bound while one was forced to help at the drive-up window. The robbers emptied the safe, tills and tip locker, prosecutors say.

Petrycki called one of the workers by name during the robbery and threatened to kill relatives and other people the workers knew, court papers say.
