LaFayette, AL – Authorities say the fire that damaged the home of Congressional nominee Bill Fuller was caused by faulty electrical wiring. Friday's fire at his LaFayette home has been ruled at an accident. Fuller is a former commissioner of the state Department of Human Resources and a former state representative. He's now trying to replace Republican incumbent Representative Mike Rogers in the Third Congressional District. The house also served as Fuller's campaign headquarters and law office. Officials say it was heavily damaged. Fuller has set up a temporary headquarters in downtown LaFayette in donated office space.
