A U.S. Postal Service report ranks the nation's capital No. 1 - for late mail delivery.
An inspector general's report released Tuesday found that mail is delivered after 5 p.m. more than two-thirds of the time in the District of Columbia and the Maryland suburbs, The Washington Post reported.
Northern Virginia also ranks high among areas of the United States getting late mail, with 69 percent of letter carriers still on their routes at night.
Both regions were well above the 38 percent national average for late deliveries from fiscal 2011 to 2013.
The inquiry was prompted by the November death of 26-year-old Tyson Jerome Barnette, a part-time carrier who was shot in his mail truck in Prince George's County at 7:30 p.m.
Barnette was killed by a hail of bullets in the 6000 block of Reed Street in Cheverly on Nov. 23, 2013.
No arrests have been made in his death.
