D.C. police Chief Cathy Lanier says investigators believe a suspect in the mysterious slayings of a wealthy Washington family and their housekeeper is in the Brooklyn area of New York City.

Lanier said at a news conference Thursday that they have been in touch with police in New York as they seek 34-year-old Daron Dylon Wint on charges of first-degree murder.

When firefighters responded to the house for a fire May 14, they found the slain bodies still inside. Authorities believe the fire was intentionally set. Slain were 46-year-old Savvas Savopoulos; his 47-year-old wife, Amy; their son, Philip; and housekeeper Veralicia Figueroa.

Lanier says investigators believe Wint worked for Savvas Savopoulos' company American Ironworks in the past.

She advises Wint to turn himself in, noting that his family has asked him to do so.
