BRIER HILL – Three people were left homeless after a fire destroyed their home Friday.

The LeGault family of 1086 Oak Point Road was not at home when the fire broke out. No one was hurt, but a dog was lost in the blaze.

Brier Hill firefighters got the call at 3:47 p.m. and found the southeast side of the house fully engulfed when they arrived, with “flames showing on all sides,” said Brier Hill Fire Chief Shawn Macaulay. His firefighters made a “defensive attack” on the fire, Macaulay said. They prevented the flames from spreading to a neighboring house.

He said the LeGault house was a total loss. It was insured.

Other departments at the scene were Morristown, Hermon, Heuvelton, Alexandria Bay, and Redwood. Gouverneur firefighters stood by at Morristown, Lisbon at Heuvelton, and elements of the Redwood department stood by at Hammond under mutual aid. Ladies’ auxiliaries from Brief Hill and Morristown helped with food and hot drinks. Town of Morristown workers sanded the area. National Grid was on scene to turn off electric service to the house. The North Country Chapter of the American Red Cross says it helped a 17-year-old family member after the fire.

Macauley said it took four hours to quell the blaze.

“All members did a great job” under difficult conditions in 7-degree weather, the chief said.

St. Lawrence County fire investigators are working to determine the cause, Macaulay said.
