On the afternoon of Thursday, June 28th, rangers Sean Brennan, Sarah Cowell and Rayne Rohrbach responded to an âofficer needs assistanceâ call just outside the park. State troopers, responding to a report of a man with a gun threatening to shoot people in a local trailer park, determined that he was in a motor home along Exit Glacier Road, the primary entry into the park. Many local seasonal workers live along the road in long-term camps established for the entire summer. Based on their knowledge of the area and its residents, the rangers immediately identified the suspectâs vehicle from the officer's description and led Seward city police and troopers to its location. As they arrived, a single shot was heard from a the motor home. Rangers immediately set up roadblocks well away from the suspect and maintained them for several hours while state and city officers began negotiations with the suspect, who was believed to have a hostage and who threatened to kill any officer who approached. These roadblocks cut off all traffic into and out of the park, stranding a large number of park visitors and staff for about four hours. The suspect, identified as William Abbott, ultimately surrendered to troopers after exiting the bus with a loaded handgun. The road into the park reopened at about 6 p.m.
