Dustin Karr, a 22-year-old male, was shot and killed just after midnight on August 7, 2016, amid a confrontation at the Berkley Village Mobile Home Park near the 5400 block of Sheridan Boulevard along the Arvada–Adams County line. He and several companions had arrived by car, words escalated, and gunfire erupted both before and after the group pulled away.
In the chaos two men were fatally wounded—Karr and 30-year-old Edgar Loera Munoz—and two others, identified as Sergio Ontiveros-Heredia and Perla Nevarez, survived with gunshot wounds. An obituary confirms Karr’s birth date of February 5, 1994, and his date of death on August 7, 2016.
Detectives pieced together that shots came from both sides: as Karr’s group drove off, his cousin Brandon Karr fired repeatedly from the vehicle toward people outside; a man at the scene, Rojelio Heredia, fired back toward the fleeing car. Investigators concluded that the round that killed Dustin Karr came from Heredia’s gun, while the volley that killed Munoz and injured others came from Brandon Karr’s weapon. The incident has since been cataloged in state and national gun-violence records tied to Arvada on that date.
Arrests followed within days. Prosecutors charged both Rojelio Heredia and Brandon Karr in the double shooting. In 2017, a jury found Brandon Karr guilty of second-degree murder, attempted first-degree murder, and second-degree assault; a judge imposed a 26-year sentence. In a separate case, Heredia received a 10-year prison term for the shot that killed Dustin Karr.
Years later, Brandon Karr’s conviction was overturned and a new trial was granted; he ultimately pleaded guilty to reckless manslaughter and assault with a deadly weapon and was resentenced to concurrent eight-year terms with credit for time served, reducing his original 26-year punishment. News accounts and court updates trace this arc from the initial conviction to the revised plea and sentence, while confirming that Heredia’s 10-year sentence for killing Dustin Karr remained distinct from Brandon Karr’s case tied to Munoz’s death and the injuries to bystanders.
