A 47-year-old man was shot and killed by two Washington policeman yesterday morning after he stabbed his girlfriend with a butcher knife and then stabbed a police officer who tried to restrain him, D.C. police reported.

Police said the struggle took place in an apartment at 2002 Maryland Ave. NE, shortly after 8:30 a.m.

They said they were summoned by Christine Johnson, 34, who said her boyfriend Franklin D. Brown, 47, had threatened her and destroyed the furniture in the apartment they shared.

When two policemen entered the apartment, Brown said he would get his clothes out of the closet and leave. Instead, police said, Brown grabbed a butcher knife and stabbed Johnson several times in both arms.

When officer Wilbur Davis tried to stop him, Brown stabbed him in the left side of the chest, police said.

Both Davis and his partner, Officer William Payne, then shot Brown several times with their revolvers. Brown collapsed on the floor. He was pronounced dead at D.C. General Hospital several minutes later, police said.

Johnson also was taken to D.C. General where she was reported in satisfactory condition yesterday.

Officer Davis was treated at Washington Hospital Center and released.

In accordance with police policy, both officers have been placed on administrative leave pending a grand jury investigation.
