Four strange lights sighted over Scottsdale, Arizona

We witnessed four objects that hovered over Scottsdale.  They were not helicopters and did not follow any flight pattern. The four objects were equidistant from each other.
After about 4 minutes one of the objects faded out, and the others followed suit.
These were not flares.  These were stationary objects.
Because of both the location, and nature, of the bright objects, we strongly suspect that the bright objects may have been aerial flares, launched from aircraft over the Barry M. Goldwater Firing Range, located near Gila Bend, AZ.  That is what official military sources apparently reported, shortly after the event had occurred, and we have no reason to doubt that claim.  PD
