Three people were wounded, one critically, when two gunmen fired semiautomatic weapons into a crowd in a parking lot about 5 p.m. yesterday.

The daylight attack in the unit block of K Terrace NW sent terrified people caught in the line of fire scattering. One man ran so hard he hit a brick wall and was knocked unconscious, police said.

"I was just amazed," said Evelyn Alston, who witnessed the attack from her porch. "I couldn't believe two people were firing like that in broad daylight. They just opened up and started firing. It almost looked like they were firing randomly."

The two gunmen, who appeared to be in their late teens or early twenties, were about 10 feet from the crowd of about 12 people, Alston said. "It was pandemonium -- people were screaming and hollering," Alston said.

The attack lasted about 40 seconds, Alston estimated, and many rounds were fired. As the gunmen ran from the crowd they continued to fire, she said. The men then escaped in a car.

Police said they knew of no motive for the shootings.

Tysean Jones, 21, of the unit block of K Terrace, was shot in the face and was taken to Washington Hospital Center, where he was listed in critical but stable condition last night.

Linda Marant, 31, of the 1300 block of Irving Street NW, was shot in the thigh. Darryl Snow, 20, of the 6300 block of Pennsylvania Avenue in Forestville, was shot in the ankle.

Marant and Snow were listed in good condition at Howard University Hospital.

D.C. police Officer Neva Taylor was in the area writing a report on a traffic accident when a man with blood on his face ran to her, police said.

Taylor had the man take cover behind her squad car and ordered bystanders to get down as bullets flew by, police said. Taylor then radioed for assistance. Police recovered a Tech-9 semiautomatic weapon.
