A Philadelphia mail carrier is accused of failing to deliver about 22,500 letters and packages that were later found in his personal vehicle and home.
Federal prosecutors said 48-year-old Patrick D'Ambrosio has been charged with obstruction of mail.
Authorities say the U.S. Postal Service worker didn't deliver the letters and parcels to their intended destinations along a route in Philadelphia's Tacony section.
Prosecutors said the failed mail deliveries happened from May 2014 through January 2015.
The mail that never reached its recipients included letters, political mailings, periodicals and small parcels.
They were later found in D'Ambrosio's personal car and in trash bags inside his Philadelphia home's garage, court documents said.
D'Ambrosio has been placed on a non-duty status, according to a Postal Service spokesman.
