Louisiana's Tiger Island wildfire ruled arson, officials say

The largest wildfire in Louisiana state history has been determined to have been arson-caused, state officials said Saturday.

The Louisiana Department of Agriculture and Forestry reported Saturday that it is asking for the public's help in finding a suspect in the Tiger Island Fire. No details were provided on exactly how investigators believe the blaze started.

The Tiger Island Fire, which broke in southwestern Louisiana's Beauregard Parish on Aug. 22, has so far burned 48.43 square miles and damaged or destroyed at least 20 homes and structures. It remains only 50% contained.
