Biologists working for the state of Washington have killed two members of the Leadpoint wolf pack this week in an effort to stop the pack from preying on cattle in Stevens County, the Washington Department of Fish and Wildlife said Thursday.

An adult male wolf was killed on Tuesday and an adult female was killed on Wednesday.

"With the removal of two wolves, the lethal removal authorization and lethal removal permit are now expired," the agency said in a news release.

Wolves killed in WA

Two wolves were killed this week in an effort to prevent them from preying on livestock.

Agency director Kelly Susewind last week authorized the killing of up to two members of the pack. That was after authorities documented five depredation events on cattle on private grazing lands since Aug. 22. Those attacks killed three head of livestock and injured two more, the agency said.

The attacks were all attributed to the Leadpoint pack, the agency said.
