VIDEO: The family of two people who died in a fire in Bar Harbor last spring has filed a lawsuit against Emera Maine claiming the company is responsible for causing the fire. 79-year-old Erlene Harding and her son, 57-year-old Leroy Harding, died when the blaze destroyed their farmhouse. Erlene Harding's husband and another son were injured. Investigators said they couldn't determine how the fire started. The family contends that in the days before the fire, a large surge of energy was supplied by Emera to numerous homes in the area. The lawsuit alleges the power surge caused severe damage to equipment including meters and was the direct result of incorrect wiring by those working with or for Emera.
