A fourth person has died after a gunman sprayed bullets from a moving vehicle into a crowd in Washington, police said Wednesday. Three suspects have been arrested in the drive-by shooting Tuesday night that injured five other people, but investigator said a motive was not clear. Six men and three women were shot in the southern part of the city, said Washington Police Department spokesman Hugh Carew. Fire Department spokesman Pete Piringer said all the victims were in their 20s and 30s except for one teenager. Police spokeswoman Gwendolyn Crump said Wednesday a fourth victim had died. Three people were arrested and a weapon was recovered. The police pursued a van from the scene, aided by a helicopter. Four Washington police officers were slightly injured while chasing a suspect's vehicle into neighboring Prince George's County in Maryland, officials said. The shootings were in a neighborhood near a water-treatment plant and Bolling Air Force Base. Some sections of southeast Washington have crime problems, but residents told local media they were surprised by the violence and did not consider the neighborhood dangerous. Washington reported 143 homicides last year, the fewest in almost 50 years.
