A veteran D.C. police officer has been charged with embezzling more than $178,000 by racking up a least 3,400 hours in overtime that she never worked, according to court documents filed in federal court.

From August 2004 to June 2008, Officer Karin Coppens submitted at least 94 fraudulent time sheets asserting that she was participating in the photo radar overtime program, a federal initiative that allows officers to earn extra money by manning speed guns in police cruisers parked along the streets of D.C.
