A 46-year-old Columbia woman was sentenced to 10 months of home detention and four additional years of probation Friday for inflating the hours she worked as a contractor to overbill the National Security Agency by nearly $109,000, the Maryland U.S. Attorney's Office announced.

Ann Warwick worked for Business Consulting Technology LLC, a subcontractor providing intelligence analyst services for the NSA, from August 2009 to July 2010, when she's accused of adding 836 hours to her time sheets, at a rate of more than $100 per hour. She pleaded guilty to making false statements.

She is one of at least 11 people charged within the past five years of bilking the security agency.
