An employee who shot dead a disgruntled worker after he gunned down two of his colleagues at a Nebraska grain elevator company was hailed as a hero and likely prevented more deaths, police officials said. The brave worker, who was not identified, retrieved a weapon and shot Max Hoskinson, 61, after the just-fired gunman went on his murderous spree at Agrex Elevator in Superior, Nebraska, on Thursday. A third person was shot but survived. Patrol Sgt. Jeff Roby said during Friday's news conference that authorities do not anticipate filing any charges against the hero marksman who shot Hoskinson. 'In fact, it's likely that the employee's actions may have prevented much further loss of life in this tragedy,' Roby said. Roby said he could not comment on whether Hoskinson targeted the victims, who were all Agrex employees. He said several other Agrex employees were on site when the shooting occurred. Authorities said Hoskinson had been fired earlier Thursday and returned around 2pm with a gun and began wildly shooting in an office area. The unnamed employee grabbed a shotgun from an office and shot Hoskinson, killing him, police said. The victims were identified as Sandra Nelson, 60, of Formoso, Kansas, and 53-year-old Darin Koepke, of Hadar, Nebraska. The unidentified third person shot by Hoskinson was treated at a hospital and released. Nebraska State Patrolman Jeff Roby claimed that the unnamed employee who shot gunman Max Hoskinson, 61, prevented more deaths.

The third victim was treated for minor injuries and released from the hospital in Superior. Hoskinson, of Superior, was pronounced dead at a hospital in Superior.

'I pray for you all and your families. I'm just so heartbroken and shocked,' she added. Local newspaper reporter Marty Pohlman said Superior, a town of about 1,800 people right along the border with Kansas, is not a place where you’d expect something like this to happen. 'Quiet, rural, agricultural. Everyone knows pretty much everyone else,' Pohlman said. 'It just shows that workplace violence can happen anywhere.' Pohlman works for the Superior Express, a weekly newspaper that covers the town and Nuckolls County. He said the county prides itself in never having a murder trial. 'You go to work in the morning, you fully expect to leave in the afternoon and go home with your family. Then something like this happens. It puts everything in context,' Pohlman said. Agrex released a statement stating they will not comment while the investigation is underway. The said their 'thoughts and prayers' were with their 'coworkers and their families.'
