A 33-year-old real estate executive was found bludgeoned to death early yesterday morning in the basement of her Dupont Circle area townhouse and her husband, a certified public accountant, was arrested and charged with homicide in the death, D.C. police reported.

Detectives said Gerry C. Wilkins, 29, the accountant, called police about 3:45 a.m. to the couple's renovated rowhouse at 1731 Church St. NW to report the discovery of his wife's body in the basement.

Police said Wilkins, who works for Comstat, and his wife managed condominiums for the Charles E. Smith Co., moved in the last few months to the Church Street address. Neighbors said they were not well known on the street.

According to one neighbor, the house is still undergoing renovation, and workers arrived there yesterday morning, apparently unaware of what had happened.

The immediate are of the intersection where the shooting occurred is known as a center for drug traffic, according to investigators.
