The cause of the Sunday fire that displaced three occupants of an East Hall mobile home is likely electrical, according to Hall County Fire Services. “We still need to conduct our follow-up but it appears to be electrical in nature at this time,” Battalion Chief Scott Cagle, fire department spokesman, said this afternoon. When firefighters arrived in the 3500 block of Gillsville Highway, about 60 percent of the single-wide mobile home was involved in fire, Cagle had said.
