"FORT HUACHUCA - The Shadow RQ-7Bv2 unmanned aircraft which lost connectivity with the ground station here Jan. 31 was found today by a hiker in the mountains west of Evergreen, Colorado.
No one was injured, but the aircraft has sustained damage.
Soldiers from Fort Carson, Colorado, along with Clear Creek County and Jefferson County, Colorado, Sheriff Departments are currently assisting with security and recovery efforts."

If the trajectory was straight then this is a simple case of a wayward drone.  If the trajectory was not straight then more investigation is needed. The article does not say.
