WACO (July 20, 2012)--A Waco woman free on $31,000 bond Friday evening after she was charged with multiple counts of prescription drug fraud for the third time in less than two months.

Shelly Lanae Davis, 42, was arrested Thursday evening on warrants charging 11 counts of fraud stemming from attempts to present fraudulent prescriptions to obtain prescription painkillers, police said.

Waco police Sgt. W. Patrick Swanton said drug enforcement investigators found Davis was calling pharmacies, representing herself as a doctor's office employee, and ordering the powerful painkiller hydrocodone.

Most of the incidents involved Walmart pharmacies, Swanton said.

On June 27, employees of the Hewitt Walmart recognized Davis when she went there to pick up a prescription, police said.

At the time Davis was named in a Robinson police warrant charging a similar type of incident.

Waco officers arrived and took her into custody on the Robinson warrant and made a case on her for attempting to obtain the drugs on that date, police said.

As drug enforcement officers began looking into the case they were able to identify eleven incidents in which Davis obtained the drugs illegally.

Warrants were obtained and the Waco Police Street Crimes Unit arrested Davis without incident Thursday evening.

Davis was also arrested on May 24 on the same charges, stemming from at least four incidents in which fraudulent prescription orders were presented to the pharmacy at the Target store on Bosque Boulevard.

The first incident was reported on March 23 and the subsequent incidents occurred on April 4, 17 and 25.

A tip from a Target pharmacy employee led to Davis' arrest.
