The Korean owner of a small Georgia Avenue market shot and critically wounded one man with a hunting rifle and frightened off two others last night during an attempted robbery of his store, District police said.

It was the second robbery-related shooting in a Korean-owned market in the city this week, the third in a month. Police gave this account:

At about 7 last night, three men, one armed with a sawed-off shotgun and another carrying a pistol, entered the Davis Market at 3819 Georgia Ave. NW and demanded money from its owner, Chang Yoon, 40.

Yoon, who was alone in the store with his wife, reached for a .30-caliber carbine he kept in a box on the counter and shot one of the men at least once in the chest. The other two men ran, dropping the shotgun on a step in front of the store.

Police identified the wounded man as Thomas E. Harris, 21, of 1456 Monroe St. N.W. Harris was underegoing surgery at the Washington Hospital Center late last night.

Yoon and his wife were unhurt.

Minutes after Harris was taken to the hospital, police roped off the sidewalk in front of the store and curious neighbors gathered in the snow.

A part-time security guard for a Safeway store across the street said the three men had been in the Safeway for 15 minutes just before the incident. He said they walked around the aisles and then left, heading across Georgia Avenue to the Davis Market.

Larry Wilson, who lives near the store in the 3900 block of 8th Avenue NW said the market has been a frequent target for robbers in the two years since Yoon bought it. "The last robbery, I think it was about a month ago, still hasn't come up for trial," Wilson said.

Yoon "was pretty upset about that last one. I guess he didn't want it to happen again," Wilson said.

The owner of the store declined to speak to a reporter as he, his wife and two children were taken by police to D.C. Police Headquarters for questioning.

He did stop long enough to wave to neighborhood well-wishers and to tell them not to worry. "We will be open tomorrow," he said.
