What is the tone of this article?

The trackers mustered at Tex Canyon Road, 20 miles north of the Mexican border, on the afternoon of March 27. There were border-patrol agents, six search-and-rescue units from the Cochise County sheriff's department and dogs trained to track escaped inmates from nearby Douglas State Prison. Several ranchers were also there, many of them descendants of the Germans and Irish who came to the San Bernardino Valley a hundred years or more ago. Back then, the ranchers settled here in part to feed the U.S. troops stationed at the border. One military mission in those days: prevent the chaos of the Mexican Revolution from spilling into the Territory of Arizona. Now another period of powerful unrest in Mexico had brought a different kind of war to the valley, and the ranchers were mindful that the violence might have claimed one of their own, a man named Rob Krentz.
