CRAIG, Colo. (AP) - A man working at Wyman Ranch east of Craig died Thursday after a bull elk gored him in its pen, authorities said.

John Renner, 57, of Craig, had worked at the ranch two days, the Moffat County sheriff's office said. Coroner Owen Grant said Renner's partner indicated they had only been in the area a few weeks.

Renner had gone into the animal's pen to feed it, even though he had been warned to stay out of the pen, sheriff's officials said.

Grant said no one saw exactly what happened.

Ranch owner Lou Wyman told the Craig Daily Press that the animal, Clyde, would probably be killed. Wyman told the newspaper that Clyde had never attacked another worker in the nine years he has owned it.

An autopsy on Renner was planned today, Grant said.
