The 44-year-old victim of a deadly bull attack has been identified as Michael Nevins, of Shepherd.
The official cause of death was blunt force and penetrating injuries of the torso, said Yellowstone County Deputy Coroner Chad Fehr.
The animal was put down Friday at the request of Nevins' wife, according to the Yellowstone County Sheriff's Department.
Pete Olsen, district investigator for the Montana Department of Livestock, identified the bull as a longhorn-Watusi cross that is commonly used as a work animal.
It's a cross between the Texas Longhorn and an Ankole-Watusi. The longhorn is a breed known for its characteristic horns, which can extend to nearly 7 feet tip to tip for bulls. The Ankole-Watusi is a breed of cattle native to Africa. Its large, distinctive horns can reach up to 8 feet from tip to tip. Ankole-Watusis weigh from 900 to 1,600 pounds
Authorities believe the attack occurred when Nevins attempted to feed the animal.
Deputies were called to 6233 Pleasant Hollow Trail, about six miles north of Shepherd, at around 9 a.m. Thursday. A neighbor looked out his window and saw the bull standing in a pasture over what later was determined to be Nevins' body.
