Dominic Johnson had a cell phone, as did Austin Barrett. Each one sent network pings that Sunday when David Grunwald went missing. Erick Almandinger had a Samsung tablet; it too periodically sent pings to the network on the evening of David Grunwald&#8217;s murder. The only one without a cell phone was Bradley Renfro, but he showed up on camera in the 11:00 p.m. timeframe, purchasing gas at a Holiday gas station alongside Dominic Johnson.<\/p>\n<p>Through these pings, then, the Alaska State Troopers tracked the whereabouts of David Grunwald &#8212; and the posse who killed him &#8212; across the entirety of that fateful Sunday: from the beating at the Almandinger trailer, to his execution along Knik River Rd, the rendezvous at Devin Peterson&#8217;s house and, then, the final stop at the foothills of the Talkeetna Mountains, where Almandinger, Johnson and Renfro torched David Grunwald&#8217;s 1995 Ford Bronco.<\/p>\n<hr \/>\n<p><img decoding=\"async\" src=\"https:\/\/lelandhale.com\/butcherbaker\/images\/grunwald-almandinger-et-al-esty-rd.png\" alt=\"Pings\" \/><br \/>\n<strong>Grunwald, Almandinger, Johnson, Barrett location<\/strong>, 7:00-8:23 p.m., November 13 (Almandinger residence on Esty Rd.)
