AUGUSTA — Federal prosecutors said a former National Security Agency subcontractor has pleaded guilty to making false statements on her timesheets.

First Assistant U.S. Attorney James Durham said 33-year-old Allison Michelle Waddell, of Beech Island, pleaded guilty in the Southern District of Georgia.

Authorities said Waddell worked as an analytic reporter for an NSA subcontractor between August 2009 and October 2010, and again from October 2011 to September 2012. Officials said Waddell submitted fraudulent timesheets saying she worked about 750 hours more than she did.

Investigators said the federal government paid Waddell more than $60,000 more than she was owed.

Prosecutors said Waddell could face up to five years in prison and a fine of up to $250,000.

Authorities said the woman has already paid about $10,000 toward restitution.
