Skeletal human remains found near two Colorado airports have likely been buried for awhile, investigators said Friday.
Sanitation workers stumbled upon the bones Thursday morning while digging for a drain at a water treatment plant by the Front Range Airport. The water treatment plant is also only a couple of miles from DIA.
Investigators worked until nightfall at the scene, and resumed their investigation Friday morning, where they dug in a trench and sifted through dirt for more evidence.
Adams County deputies told sister station KCNC that they don't know how long the bones have been there, but they don't believe they were buried recently.
At this time, the age and sex of the individual are unknown.
