Fire crews called in extra firefighters to battle the blaze. The mansion’s owners, Patty and Charles Garney, were home at the time of the fire. Patty Garney told KMBC's Brenda Washington that she knew something was wrong while looking at a skylight.

"I saw a glow that I knew should not be there. Then after looking at it for just a few seconds, I realized that it was fire. So I ran in the bedroom and woke up my husband and we got our house guest, got the dog and got our cars and got out," Patty Garney said.

Fire officials said the house, estimated at $5 million, was a total loss.

The Garneys spent much of the day on Friday recovering heirlooms, paintings and anything else that could be salvaged from the home.

Investigators told KMBC's Mike Mahoney that they don't think they'll ever be able to determine a cause. But they do think the fire started in the roof or attic, and they don't think it was intentionally set, or that any neighbor started it.
