Federal prosecutors say they won't pursue a criminal case against two Idaho sheriff's deputies who shot and killed an armed rancher, coming the same day the state attorney general decided not to file charges.

U.S. Attorney Wendy Olson said Friday that the Nov. 1 death of Jack Yantis was a tragedy, but the evidence doesn't show the deputies intended to break the law. She says her office notified Yantis' family of the decision.

Yantis was killed after one of his bulls was hit by a car and the deputies tried to put down the animal.

Olson's office says no audio or video recordings exist though both deputies were issued body cameras. Instead, investigators relied on testimony from the deputies and two civilians.

The Idaho attorney general also announced Friday that he wouldn't pursue criminal charges.
