OMAHA, Neb. (AP) — A former pharmacy director has pleaded guilty to stealing more than $4.6 million from an Omaha hospital.

Federal prosecutors said Monday that 49-year-old Lisa Kwapniowski, of Omaha, pleaded guilty to committing wire fraud. She’s scheduled to be sentenced April 29. The prosecutors say Kwapniowski will be ordered to pay restitution as part of her sentence.

Court records say that sometime before 2010, Kwapniowski submitted to Children’s Hospital & Medical Center fraudulent invoices from legitimate pharmaceutical suppliers. She later submitted reimbursement requests utilizing fraudulent invoices from a company she fraudulently created.

Prosecutors say she also submitted fraudulent invoices that appeared to come from a legitimate drug vendor and used fraudulent means to obtain payments.

She was fired in June after accusations arose.
