The Boulder County District Attorney's Office announced Wednesday it will not charge anyone in connection with the fire that killed two dogs and nearly destroyed a Superior duplex earlier this month.

Investigators determined the fire was started by kids playing with a lighter, and the case was reviewed by prosecutors to see if any arson charges applied to the adults in the case.

But DA Stan Garnett said Wednesday that no charges will be filed in the case.

"We reviewed the evidence, and there are a lot of different levels of arson, but we concluded the evidence did not warrant any criminal charges," Garnett said. "There was no crime that could be proved beyond a reasonable doubt on anybody old enough to be charged with a crime."

The children in the case are under the age of 8, and Colorado law does not allow children under 10 to be criminally charged.

The fire started at about 12:10 p.m. Aug. 17 in the 300 block of Third Avenue in Superior. One family was home at the time and was able to get out of the house without injury.

The duplex neighbors, Chris Rizer and Kristen Rizer-Lohneiss, came home from a camping trip to find their house on fire and would later learn their two dogs --Saphire, a black Labrador-pit bull mix, and Zeak, a Swiss mountain dog-German shepherd mix -- had died.

Their cat, Abby, is also still missing.
