A woman was shot Tuesday night on the southeastern edge of Capitol Hill, about one mile from the tightly guarded Capitol, where President Obama gave the State of the Union address.

The woman was not seriously wounded in the incident near 14th Street and Pennsylvania Avenue SE, police said. Officers said the man they were looking for appeared to be wearing a FedEx uniform.

The shooting was reported about 9 p.m. as the president was scheduled to begin his speech. The site was within a block or two of the Potomac Avenue SE Metro station. A Metro spokesman said the incident did not involve the transit system.

Earlier Tuesday, three juveniles were wounded in Northeast Washington, D.C. police said. Their wounds did not appear to be serious.

Lt. Sean Conboy, a department spokesman, said two of the youths were grazed by gunshots. Another was hit in the hand, he said.

The ages of the three victims were not immediately known.

Although the wounds appeared relatively minor, the vicinity of the shooting appeared to erupt in chaos, according to police accounts.

Police said those who were shot were found in at least two spots.

The first report of the shooting came about 3:30 p.m. and sent officers to the 1500 block of Isherwood Street NE, between D and E streets.

The motive for the gunfire remained unclear Tuesday night, and it could not be learned whether the victims were the intended targets.
