BANGOR — The former head pharmacist for the Penobscot Indian Nation’s shuttered mail-order pharmacy is going to prison for soliciting and taking kickbacks from Internet drug companies.

Reginald Gracie Jr., who pleaded guilty to receiving kickbacks and filing false tax returns, was sentenced Wednesday to 3 years and 10 months in federal prison.

The 40-year-old Gracie of Bowdoin was charged with receiving more than $120,000 from six online companies in 2006 in return for making sure the tribe’s mail-order pharmacy, known as PIN Rx, filled the prescriptions of the companies’ customers.

Prosecutors say Gracie also failed to report his illicit income on his income tax return and on a 2006 corporate income tax return for Gracie Enterprises, Inc.
