A former compliance officer for the National Labor Relations Board pleaded guilty this week to stealing more than $400,000 from an agency fund.

Hector โ€œSonnyโ€ Martinez, who worked in the NLRBโ€™s Los Angeles office, was charged with the crime in June. He pleaded guilty on Aug. 21 in U.S. District Court for the District of Columbia. The formal charges from the U.S. Attorneyโ€™s office include wire fraud and โ€œaggravated identity theft.โ€
