State wildlife officials have euthanized a grizzly bear after it killed at least three calves over the past two weeks on a ranch near Augusta.

Fish, Wildlife and Parks bear management specialist Mike Madel said the 7-year-old, 514-pound male grizzly was euthanized Friday morning after it was captured on a ranch southwest of Augusta.

Madel said it was believed to be the first time the bear killed livestock, but there was a strong suspicion it would continue to do so.

This is the third time this year an adult male grizzly bear has been removed from the Rocky Mountain Front after a livestock depredation.

And on Wednesday, Madel helped capture and relocate a sub-adult male grizzly that broke into a ranch outbuilding near Augusta to get at livestock grain feed.
