OMAHA, Neb. (AP) — Douglas County officials say the FBI and IRS have taken over an investigation into an event-planning business and its owner, who’s accused of selling thousands of worthless travel vouchers.

The Douglas County Attorney’s Office still will continue its prosecution efforts against Patricia Urbanovsky, who’s charged with three felony counts of theft.

She’s the owner of the business, Creative Creations, in Omaha.

A pretrial hearing is set for Sept. 17 in Douglas County District Court.

The FBI served a search warrant last week on an Omaha residence that Urbanovsky stayed in. An IRS spokesman declined to comment Tuesday, citing an ongoing investigation.
