Investigators in Oklmulgee are trying to figure out what started a fire in the downtown area for the fourth time this year. Firefighters were called to Tucker's Furniture Saturday evening. Investigators say the owner lost his other furniture store to a fire about a month ago. That store was about a block away. People in Okmulgee say its tough seeing another destroyed downtown building. Okmulgee resident, Brandon Ritch says "I think it is terrible. It's going to be a ghost town pretty soon if we don't watch out." Authorities say it's too early to even speculate how the fire started. They say they couldn't determine what started last month's fire.
