FRANK SESNO, CNN ANCHOR: To the search, now, for a gunman who opened fire yesterday outside the National Zoo here in Washington, the nation's capital. Seven children were wounded and one of them is in critical condition with a brain injury. CNN's Kathleen Koch is outside the zoo, which remains closed today -- Kathleen.</s>KATHLEEN KOCH, CNN CORRESPONDENT: Frank, it was supposed to be a happy day here at the zoo, one of the most popular attractions in Washington, drawing some 3 million visitors every year. It was Easter Monday, a time for the African-American family celebration. But shortly after the music and the egg hunts ended, gunfire broke out right here at the entrance to the zoo. Seven children between the ages of 11 and 16 were shot. Now, most will recover, but one boy who was shot in the head remains on life support systems in critical condition. Police say that it all started with an altercation between two groups of teenagers.</s>CHIEF CHARLES RAMSEY, D.C. POLICE DEPT.: These groups had been in conflict for a good part of the afternoon, going at one another. But it wasn't until they were put out of the zoo and they were standing on Connecticut Avenue, one group on the west side of the street, one on the east side of the street. They started throwing bottles back and forth, and then someone pulled a gun and began firing into the crowd.</s>KOCH: Police say they have good leads on a suspect: an African- American male in his late teens, between 5'8" and 5'10" of slight build, wearing a dark jacket and baggy blue jeans. Several rewards have been offered for information that leads to the arrest of the person responsible. And, Frank, because of this shooting incident, there are now calls to beef up security at this one of the few remaining free zoos in the country. Reporting live at National Zoo, I'm Kathleen Koch.
