A U.S. Postal Service worker has been charged with stealing mail — mostly envelopes she suspected contained gift cards — from the Arlington Main Post Office.

According to an affidavit filed in U.S. District Court in Alexandria, Alva D. Jackson, an Arlington mail carrier, allegedly stole items from the mail from October 2008 to March 2010.

She stole and used gift cards for Target, Macy’s, Best Buy, Wal-Mart and various restaurants, according to the affidavit. Jackson estimated that she took about 10 to 20 pieces of mail per week during the holiday seasons, and 10 or fewer pieces at other times.
