A shootout last year at the Sunset Village Mobile Home Park in Hiawatha that left three men injured and a fourth man dead will not lead to major criminal charges.After authorities investigated the chaotic events around the May 30, 2020, gunfight, Linn County Attorney Jerry Vander Sanden announced Friday the killing of Joshua Lathrop, 31, was justified under Iowa’s “stand your ground” self-defense law.Only one charge — of illegally carrying a gun — will be filed against one of the combatants.According to the investigation findings, officers were dispatched at 11:40 p.m.
