A government contractor on Tuesday pleaded guilty to submitting false claims while working for the National Geospatial Intelligence Agency at Fort Belvoir.

Thomas J. Cicatello, 32, of Woodbridge, admitted to filing time reports claiming he worked for hundreds of hours reviewing sensitive data vital to troops in war zones when he was actually not at work.

As an analyst, his job was to review intelligence on the location of the bombs known as “improvised explosive devices” in Iraq and Afghanistan. The information he compiled in reports was sent to service members, “who relied on the accuracy of the information they received to make strategic decisions,” according a statement issued by the U.S. Attorney for the Eastern District of Virginia.

Prosecutors said he covered his absences by filing reports that said, “NSTR,” or “nothing significant to report.” He faces a maximum of five years in prison.

Aamra S. Ahmad, Cicatello’s attorney, declined to comment.
