From NBC Washington:
Two people were killed and three others were shot Wednesday in Southeast D.C., prompting a massive police presence and a harsh rebuke of gun violence from District officials.
D.C. Police and D.C. Fire and EMS were called shortly before 1:30 p.m. to the 1300 block of Congress Street SE in the Congress Heights neighborhood for the report of a shooting.
Upon arrival, Police Chief Robert Contee said officers found four people who had been shot. They were taken to hospitals, where one woman and one man died.
A fifth person walked into a hospital and was being treated for injuries that were not life-threatening, Contee said.
It is unknown what caused the shooting, but there appeared to be a dispute between two groups of people, the chief said.
