Flags in Maryland are flying at half-staff in honor of Peace Officers Memorial Day, a day honoring law enforcement officers who have died in the line of duty.
Gov. Martin O'Malley ordered the U.S. and Maryland flags flown at half-staff on Wednesday.
Peace Officers Memorial Day is celebrated on May 15 each year. The service begins at 11 a.m. on the west front of the United States Capitol. President Obama is scheduled to speak there Wednesday.
Peace Officers Memorial Day is recognized during National Police Week.
Fallen officers were also honored at the beginning of the week with the addition of 321 names to the National Law Enforcement Officers Memorial in Judiciary Square. National Police Week wraps up Thursday with day two of the National Police Survivors Conference, an event for surviving family members and colleagues of fallen officers.
