Mobile fire and arson investigators returned to Timber Ridge apartments Tuesday searching for answers in the aftermath. Sunday’s fire in Mobile left dozens of people displaced; officials still looking to determine what caused the blaze. TJ Johnson was inside of her apartment when her building caught fire. She ran out with just the clothes on her back and said she’s lucky to be alive. “I was awoken by a very loud thud up above me…then, I saw thin black smoke trickling it…I got close to the door and there was a lot of heat emanating from the door and I was like ‘oh my goodness! It’s on fire’”, Johnson said.
