El Paso County sheriff Terry Maketa said Monday that local, state and federal investigators are "zeroing in on the point of origin" of the Black Forest Fire near Colorado Springs. It's 75 percent contained.

Nearly 500 homes have been lost in the fire and two people who were trying to flee were found dead in the rubble.

The investigation is one reason authorities have been hesitant to let people back to the area hit hardest by the fire. Firefighters are also working to put out hot spots. Maketa said residents could be temporarily allowed back as early as Tuesday.
