"My neighbors are just heartbroken, too", she said.
Etowah County authorities have questioned one person of interest but no arrests have been made in connection with the incident.
Tina Johnson, who claims Moore groped her rear at his office over two decades ago, was at work when her Gadsen home went up in flames on Tuesday morning, cops said.
Nobody was hurt in the blaze, and the Etowah County Arson Task Force is investigating, said Entrekin.
"I am devastated, just devastated", Johnson told The Birmingham News.
By the time the fire had been put out, the home and all of Johnson's belongings had been lost.
In an interview with NBC's Megyn Kelly in mid-November, Johnson said she was in her 20s and was signing custody of her son over to her mother when Moore touched her.
"More details will be released when warrants are obtained".
Johnson and her family are living in a motel while their friends and neighbors help them recover from the blaze.
Several of Johnson's neighbors noticed a young man with a reputation for public intoxication and misbehavior loitering around the property Tuesday morning.
"I threw on my coveralls and took off down the driveway", he said, adding that his wife called 911, but the dispatcher said the fire had already been reported. Moore lost a runoff last month to Doug Jones, a Democrat.
Moore has denied all the accusations.
