Federal officials say they are investigating the poisoning deaths of four wolves and six eagles found in May in Montana's Bob Marshall Wilderness Area.
The U.S. Fish and Wildlife Service said in a statement Monday that the animals were found near the Big Prairie Ranger Station. Recent laboratory results concluded that the animals died of poisoning, and officials are seeking information that will lead them to those responsible. The agency is offering a reward of $2,500 for information that leads to a conviction.
The Fish and Wildlife Service is investigating along with the U.S. Forest Service and the Montana Department of Fish, Wildlife and Parks.
