A third improvised explosive device was found near Parque del Sol in Sahuarita on Friday evening — investigators with the bomb squad and ATF are testing it after two similar discoveries on June 13 and June 20.

Police said a shooting on Friday at Quick Trip Pawn on Tucson’s Northside left one man dead—another was wounded with life-threatening injuries and taken to a hospital.

This research adds strong new evidence to the debate over the timing of human migration to the Western Hemisphere.
