A woman was fatally stabbed on 14th Street NE last night and two men shot in the District in unrelated incidents died of their wounds yesterday, including a man shot in the head while driving on Capitol Hill during rush hour Thursday evening.

The stabbing raised to five the number of homicides or apparent homicides in the first four days of this year.

About 7:30 p.m. yesterday, authorities were called to an apartment in the 2500 block of 14th Street NE, where they found a dead woman who appeared to be in her thirties.

Earlier yesterday, Kenneth Goshorn, 46, of the 7600 block of Fontainebleau Drive in Riverdale, died about 11 a.m. after being shot Thursday evening while driving his car on Pennsylvania Avenue at 11th Street SE, according to D.C. police. He was the city's third homicide victim of the year.

Police released no additional information about their investigation of Goshorn's death, which they said may have been a random shooting. A friend described Goshorn as a lawyer who had been involved in political campaigns in California.

The District's fourth homicide victim of 1991 was Jeffrey Pinnix, 21, address unknown, who died about 12:40 p.m. yesterday at Washington Hospital Center of gunshot wounds he received 13 hours earlier, a hospital spokeswoman said.

Police said that Pinnix was one of three men shot in an incident shortly before midnight in the 2500 block of Naylor Road SE.

They said that when officers arrived to investigate a reported shooting, they found the three victims had already been taken in private cars to Greater Southeast Community Hospital.

At the hospital, police found Pinnix; Robert Stoddard, 20, of the 1200 block of First Street SE; and William Bain, 23, of the 1500 block of Second Street SE, all with gunshot wounds. The three were transferred to Washington Hospital Center.

A spokeswoman there said yesterday that Stoddard was listed in critical condition after surgery for gunshot wounds in his head and chest, and Bain was in fair condition with unspecified gunshot wounds.
