A husband and wife accused of killing a man in Northeast Washington on Saturday were still in the same room as their dying victim when police arrived, and the wife told officers "I punished [him]," according to court papers.

Charlotte Nickelson, 21, and Russell Nickelson, 28, face charges of first-degree murder while armed in the death of William Johnson, 33. Both were ordered held without bond yesterday in D.C. Superior Court.

In charging documents, police say Johnson, of the unit block of Farragut Place NW, had come to the apartment to confront Charlotte Nickelson because of an incident in which his friend's tires were slashed.

The documents described the scene in their apartment in the 600 block of Edgewood Street NE when the first D.C. police officers arrived about 3:50 a.m. Saturday.

Police found Johnson on the living room floor, semiconscious, with stab wounds to his head, body and legs.

He asked for water, the documents say, and told police that the Nickelsons had taken his money.

The Nickelsons also were in the room, police said, and both had blood on their clothing.

"This [expletive] knocked on my door and punched me in the face. So I punished" him, Charlotte Nickelson allegedly said to officers. "So I split his [expletive] head."

When Johnson asked for water, Nickelson allegedly told him "Shut up [expletive], you ain't getting no water in here."

The documents quote witnesses who said that, before police arrived, Russell Nickelson struck Johnson in the head with a ceramic lamp, knocking him down. Then, the witnesses said, the Nickelsons began punching and kicking Johnson, and Charlotte Nickelson stabbed him in the legs and torso.

Johnson died about an hour after he was found by police, and was later determined to have suffered fatal stab wounds to the chest and legs, the documents said.
