WASHINGTON (AP) — Authorities have arrested an ex-convict who's accused in the killings of a wealthy Washington family and their housekeeper.

Members of a fugitive task force arrested 34-year-old Daron Dylon Wint around 11 o'clock last night, about a week after authorities say the family was killed and their mansion was set on fire. Wint has been charged with first-degree murder while armed. Several other people were taken into custody with him.

Investigators had tracked Wint to New York City, where U.S. Marshals say they barely missed him Wednesday night. Wint was then tracked to a Howard Johnson Express Inn in College Park, Maryland, and officers followed him into northeast Washington last night.

Police haven't detailed why Wint would want to kill 46-year-old Savvas Savopoulos, his wife, their 10-year-old son and the housekeeper. Three of the four victims had been stabbed or bludgeoned before the fire.

Wint, a certified welder, had worked at one time at American Iron Works, where Savopoulos was CEO.
