COLORADO SPRINGS, Colo. (AP) - Fire investigators still do not know who caused the Waldo Canyon fire, the most destructive wildfire in Colorado history.
Fire officials have tentatively scheduled a news conference for Wednesday, but few new details of the investigation are expected.
Investigators have said they believe the fire was caused by a human, but no suspects have been identified.
On June 23 the wildfire exploded and went on to destroy nearly 350 homes and kill two people.
