BANGOR (AP) — An Augusta woman described by authorities as the driving force behind a pharmacy robbery in the city has been sentenced to nearly four years in prison.

Stephanie McCormick was sentenced Tuesday in federal court in Bangor to three years and 10 months behind bars and three years of probation. She was fined $1,000 and ordered to pay nearly $1,600 in restitution.

The 23-year-old woman pleaded guilty in March to aiding and abetting the January robbery.

Prosecutors said her cousin, 20-year-old Anthony Post, pulled off the heist, walking into the pharmacy and handing a worker a note demanding oxycodone and claiming he had a gun.

But authorities said McCormick planned the robbery, wrote the note, arranged for a getaway driver, and took a share of the stolen pills.
