A 34-year old lawyer and staff member of a committee of the House of Representatives was found stabbed to death yesterday afternoon in the basement of his town house in Georgetown, D.C. police reported.

The victim was identified as James C. Rogers Jr., minority counsel to a subcommittee of the House Committee on Interior and Insular Affairs

Discovery of the body about 3 p.m. brought eight police cars and two ambulances to the victim's home at 1331 35th St. NW, and created a stir in the neighborhood, which is one block from Georgetown University.

The slaying was still under investigation late last night and detectives remained inside Rogers' three story brick house, searching for evidence.

Earlier, as neighbors looked on intently, police spent two hours dusting for fingerprints on Rogers' blue BMW automobile, which was parked around the corner on O Street NW. The vehicle was then towed away.

Police said they had no suspects and knew of no motive.

Neighbors said Rogers' body was found by painters who were working yesterday on the newly renovated house, which bears a plaque denoting it as a historic landmark.

According to the neighbors, Rogers, who had been home most of the day, had left in the early afternoon, apparently on an errand connected to the renovation of the house, which has been under way for more than a year.

A native of Florida and a son of a banker, Rogers' was a graduate of Stetson University law school. He had worked on the Hill for five years. He began working this year in his present post with the subcommittee on water and power resources.

Before going to work on the hill he had worked in the Treasury Department and for the Securities and Exchange Commission.
