Hall County Fire Services is still investigating a suspicious Sept. 7 fire that destroyed a 15,000-square-foot home in North Hall, but officials are having trouble getting in touch with the bank that owns the property. “We have attempted a couple of times and keep getting hung up on with no return calls,” Hall County Fire Marshal Scott Cagle said in a news release. He said the department has interviewed numerous people and have some “decent leads, but nothing concrete.”
