KATONAH, N.Y.--The cause of Tuesday morning's fire at 23 South Road in Katonah was still unclear Wednesday morning, fire officials said.
The blaze was the third major fire Bedford companies encountered in town since the year began.
Tuesday's fire caused extensive damage to the 40 by 30 foot wood frame Cape Cod style house, officials said. By the time the Katonah Fire Department knocked down the flames, which took about 20 minutes, much of the second floor had been destroyed, according to officials.
Firefighters had to knock out the home's second floor windows to battle the flames, but were successful in keeping the fire contained to the second floor of the structure, officials said.
The homeowners were not inside when the fire began around 10:20 a.m., according to officials.
The Mount Kisco Fire Department and Bedford Hills Fire Department also responded after a confirmation of heavy smoke by Bedford Police.
The Westchester County Cause & Origin Team was continuing to investigate the incident. Causes are still unknown for the year's two previous fires: one on New Year's Day at 334 Hook Road in Katonah and another at 109 Stone Bridge Lane in Bedford Hills on the night of Jan. 8.
