Spencer Platt/Getty Images Four members of a militia group associated with the extremist "boogaloo" movement have been indicted on obstruction charges related to the killing and an attempted killing of two federal law enforcement officers in California last year, the Department of Justice announced on Friday. The indictment alleges that Jessie Alexander Rush, 29; Robert Jesus Blancas, 33; Simon Sage Ybarra, 23; and Kenny Matthew Miksch, 21 — members of a Northern California-based militia group — conspired to destroy communications and other evidence linked to the killing of Federal Protective Services Officer Dave Patrick Underwood last May, and the killing of Santa Cruz Sheriff's Sgt. Damon Gutzwiller the following week.
