A Granite Falls woman accused of forging more than 100 prescriptions for painkillers allegedly told police she did so while working at a Woodbury urology clinic as she struggled with opiate addiction.

Andria Kari Lindberg, 31, now faces charges of first-degree drug possession and identity theft, both felonies.

Authorities believe the crimes Lindberg is charged with occured from February to December 2015.

According to the criminal complaint filed in Washington County:

An Eagan pharmacy notified Metro Urology in Woodbury of suspicious prescriptions they apparently received from the clinic's providers.

The prescriptions, mostly for Percocet and Oxycodone, were written for Lindberg, who worked at Metro Urology from 2009 to 2015, and at least two other people who shared her last name.

Lindberg worked directly under the provider listed on the prescriptions and had access to prescription writing software during her employment.

The prescriptions were filled at pharmacies in Eagan, Woodbury, Apple Valley and Burnsville. Each one was erased from the system after they were printed.

Lindquist wrote prescriptions for more than 4,000 Percocet and Oxycodone pills during that time.

All three providers with whom Lindquist worked directly denied prescribing her those medications.

Lindquist was charged with third-degree DUI in September 2015 after a blood test revealed traces of at least three opiates in her system, two of which matched prescriptions she filled in the previous two days.

During a police interview at Lindquist's home in Granite Falls, Minnesota last year, Linguist said she wrote the prescriptions and forged a provider's name over a 10-month period.

She said she had been "horrible addicted" to painkillers, had since completed a treatment program and was employed.

Lindberg was booked into the Washington County Jail March 1. Her initial court appearance is scheduled April 2.
