Off-duty Chattanooga firefighters are doing what they can to help the three children who lost their parents in a terrible fire last month. 

Rebecca, 10, Haley, 9 and Mark, 8, are staying with their grandparents, Susan and Gary Patterson, who live just around the corner from where the fire took the lives of their parents Randall and Candy Lockhart on Houser Street in November. 

On Tuesday, off-duty firefighters were there, with power tools in hand to repair the Pattersons small house on Van Dyke Street.

 “This tragic fire had a tremendous impact on all of us. We're just trying to make a few improvements here that will help the kids, and the grandparents, who didn't have a lot of resources to begin with,” said  Captain Ashley May, coordinator of the project.  

Officials tell Channel 3, firefighters are repairing a bathroom and making it handicapped accessible for one of the kids, and they're also repairing vinyl siding on the house.

Anyone who would still like to help this family can still do so by making a cash donation to the “Lockhart Relief Fund” at any First Tennessee branch office.
