For the Cathey family, a normal Monday afternoon turned into a nightmare. The Flowery Branch family’s home was up in flames and smoke when Mark Cathey was pulling into the driveway with his two girls, Harper, 3, and Hayleigh, 5, around 3:40 p.m. Rachel Cathey, Mark’s wife, was on the phone with him when he saw what was left of their home. “We were just having a casual conversation, then sheer panic,” Rachel said.
