Dustin Karr, 22, was shot and killed just after midnight on August 7, 2016, during a confrontation at Berkley Village Mobile Home Park near the 5400 block of Sheridan Boulevard on 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. Two men were fatally wounded in the chaos — Karr and 30-year-old Edgar Loera Munoz — while two others, identified as Sergio Ontiveros-Heredia and Perla Nevarez, survived with gunshot wounds.

Detectives determined that shots came from both sides: as Karr’s group drove off, his cousin Brandon Karr reportedly fired repeatedly from the vehicle toward people outside, and a man at the scene, Rojelio Heredia, fired back toward the fleeing car. Investigators concluded 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. Arrests followed within days and both Heredia and Brandon Karr were charged in the double shooting.
