The Alaska State Troopers announced Tuesday that a court services officer was killed after he was attacked by a muskox outside his house. Curtis Worland was attempting to scare off a group of the beasts near a dog kennel at his home when one attacked him, the troopers said in a statement. Worland was declared dead at the scene in Nome in the west of the state. Troopers spokesperson Austin McDaniel explained that court services officers are law enforcement officers responsible for courthouse security, prisoner transport, and court document services. Muskoxen are long-haired, horned animals which can weigh up to 800 pounds, the state Department of Fish and Game said. The agency is now investigating the incident along with the Alaska State Troopers and Alaska Wildlife Troopers.
