Eichelberger described all three as being in critical but stable condition. The other three victims were transported to George Washington University Hospital and Georgetown University Hospital. Seven people were transported by ambulance from the scene of the shooting. Aside from the six, one was transported for a seizure. A pregnant woman was treated at the scene, officials said.
Police helicopters are in search of a suspect.
He was last seen heading south on Connecticut Avenue. The zoo planned to remain closed Tuesday. It is just a terrible, terrible tragedy. The shooting occurred as the zoo was about to close for African-American Family Celebration Day. Witnesses said the shooting started when a bottle was thrown.
