ANNAPOLIS, Md. (AP) - Investigators are back at the scene of a massive fire that reduced an Annapolis-area mansion to rubble.

They're focused on finding out what caused the early-morning fire on Jan. 19, believed to have killed Don and Sandra Pyle and their four grandchildren, two sets of siblings ages 6 to 8.

Investigators recovered the last of six bodies believed to have been in the rubble on Monday, one week after the blaze destroyed the 16,000-square-foot waterfront mansion.

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  1/2 baths. The flames took hours to put out Monday after the fire began before dawn on the outskirts of Annapolis.
