A man sought for questioning by D.C. police in the death of a 47-year-old Southeast woman whose decomposed body was found in a vacant house last month was arrested in Fayetteville, N.C., after he was stopped by state troopers for traffic violations, police said yesterday.

They said Russell Lee Scott, 45, was taken into custody Monday on Rte. I-95 in Cumberland County, about 65 miles south of Raleigh.

Although the time and details of the arrest were unavailable, Scott was charged with driving with a revoked license, possessing a fictitious registration, and not having insurance, said Sgt. Gary Scearce of the Fayetteville police.

Scott also is wanted on outstanding warrants charging him with parole violations.

D.C. police began trying to locate Scott shortly after his one-time girlfriend, Sarah Nell Mosby of 5032 E St. SE, was reported missing by her family on Sept. 24.

Mosby had failed to return home from a shopping trip to the Hechinger Mall at 17th Street and Benning Road NE.

Police later listed Mosby as a critical missing person when they learned she suffered frequent blackouts resulting from a gunshot wound in the head she had received several years ago. On Nov. 9, Mosby's body was discovered in the attic of a house on Georgia Avenue NW. D.C. medical examiners have not determined the cause of her death, police said.

Scott had been convicted on gun charges stemming from the Mosby shooting, D.C. police spokesman Lt. William White III said last night. A homicide investigator is in Fayetteville to question Scott, White said.

Sgt. Scearce said Scott is being held at the Cumberland County jail awaiting extradition by federal marshals.
