ANNAPOLIS, Md. (AP) — Six members of a family are unaccounted for after a fierce fire reduced a multimillion-dollar waterfront mansion near Maryland's capital to a scorched stone framework. Teddy bears and flowers now rest near the front gate and teary-eyed neighbors have stopped by.

On Tuesday, federal fire investigators are expected to arrive after first light, seeking a cause for the flames that gutted the 16,000-square foot home with seven bedrooms and 7 ½ baths. The flames took hours to put out Monday after the fire began before dawn on the outskirts of Annapolis.

Capt. Russ Davies, a spokesman for the Anne Arundel County Fire Department, says they know who's unaccounted for and that looking at the damage, it would not be a stretch to think anyone in the house died in the fire.
