NEWPORT NEWS, Va. — A former secretary at Langley Air Force Base has been sentenced to four years in prison for bilking the government out of nearly $1.5 million over 17 years.

The Daily Press reports 52-year-old Michelle M. Holt was also ordered on Wednesday to repay the money, which came mostly from faked overtime hours.

The civilian worked in Air Combat Command's communications support squadron. According to documents submitted as part of a December plea agreement, she falsely claimed nearly 43,000 overtime hours between December 2001 and July 2018.

The documents say Holt grew bolder over time, and by 2008, her overtime pay exceeded her regular pay. In 2017, she took home more than twice her $51,324 salary in overtime pay alone.

She faced up to 15 years. Prosecutors acknowledged Holt accepted responsibility.
