Six people are missing after a 4-alarm blaze destroyed a 16,000-square-foot mansion in Annapolis, Maryland early Monday morning, a fire department spokesman said.

Capt. Russ Davies of the Anne Arundel County fire department said Monday afternoon that six people are unaccounted for in the aftermath of the early morning blaze in Annapolis.

He declined to say who specifically could not be located but officials had been talking with other relatives. Earlier, Davies had said the home's occupants might have been out of town.

According to the Capital Gazette, the mansion, which is worth $6.2 million, is owned by Don and Sandra Pyle.

In an October 12, 2014 interview in the Washington Post, Don Pyle is identified as the chief operating officer of an IT company known as ScienceLogic.

A neighbor told the Capital Gazette that the Pyles are “lovely people.”

The fire began about 3:30 a.m. and was brought under control several hours later. Firefighters remained on the scene into the afternoon next to the mansion, which had been reduced to its stone framework.

A neighbor, who lives 500 yards from the home, told the paper he woke up at 4:30a.m. and noticed an orange glow in his bedroom.

“It was like an inferno, he said. “The flames seemed to shoot straight up.”

Fire officials have yet to determine the cause of the fire.
