COLORADO SPRINGS, Colorado — The El Paso County Sheriff's Office and the district attorney said Tuesday they don't have enough evidence to prosecute anyone on criminal charges in connection with the Black Forest fire last year and the cause remains a mystery.
"The only clear established fact was that no natural causes existed and thus the fire was human-caused," the Black Forest Fire Investigation executive summary concluded.
Investigators said they found "metallic particles" near the origin that could have been the source of ignition, but the investigation was not conclusive.
They ruled out power lines, railroad activity or a gas leak. Investigators also said there is no evidence that the fire was caused by blasting, fireworks, welding or target shooting.
According to the report, the area where the fire started did not have an easy escape route, such as a road nearby, something that is typical with fires that are intentionally started.
The Black Forest fire started June 11, 2013 in an area southeast of Denver. It was 95 degrees and wind was blowing up to 40 miles an hour.
The blaze killed two people, destroyed 14,280 acres and 489 homes, and cost $9.2 million to fight.
