The state Department of Homeland Security says the cause of a northern Indiana house fire that killed a state trooper and her daughter has been ruled undetermined.
Trooper Stephanie Thompson and Mya Thompson died Feb. 17 after a fire fully engulfed their Monticello home.
The scene was examined by department investigators as well as investigators and engineers from the federal Bureau of Alcohol, Tobacco, Firearms and Explosives, the agency said.
