The man, Eric Traylor, who lives in the 2200 block of 13th Street, said he saw the vehicle crash through a gate at W and 13th streets. "Everybody screamed at her, 'Stop! Stop!' "
One victim Traylor saw was a woman whose skin had been torn from her body as she was dragged, he said. He also saw an unconscious man bleeding from the head.
Relatives spent much of the night in an anxious effort to find family members who had been taken all over the city for treatment.
Andre Johnson and three relatives were on Good Hope Road SE watching the festival when the car headed toward them. Demari Robinson, who is 23 months old, was in a stroller, and Johnson swung it out of the way.
Johnson was struck, and the boy was scraped. Both were being treated at hospitals late last night, according to Shirl Scales, a family member.
She said another relative, a 13-year-old girl, was taken to Georgetown University Hospital, with a possible broken leg.
Still another member of the family had not been located, Scales said.

Martin Luther King, Jr. Avenue, SE in Anacostia.
A car plowed into a crowded street festival in Washington, DC Saturday night, injuring up to 40 people, including at least two police officers. The scene occurred in the Anacostia region of the city, during Unifest, an annual street festival sponsored by a local church. 

The car, driven by 30-year-old Tonya Bell, of Oxon Hill, Maryland, had a 7-year-old child in the front seat, and was believed to have been traveling at speeds of up to 70 MPH when the incident occurred.

Bell has been charged with aggravated assault while armed for the incident; the child in the vehicle was unharmed. Mayor Adrian M. Fenty said the city would "do everything we can to make sure the victims get the best care." Witnesses say the car never stopped, and describe the scene as crazy and chaotic. 

Event goers, police, and others in the area attempted to stop the car, but say Bell was "doing this purposefully," and she was not going to stop.

Fenty commented that one of the bright spots of this incident was that those who were injured are now being stabilized. Before visiting one of the victims of the incident, a 4-year-old, he said "it looks like everyone is going to pull through."
