The carcasses of three wolves "frozen solid" were found dumped in a ditch along a northern Minnesota highway in what conservation officials are confident is a case of poaching, federal authorities said Thursday.
The discovery on Hwy. 8 near Floodwood, about 35 miles southeast of Grand Rapids, was reported on Jan. 22 to a state Department of Natural Resources poachers tip line, according to the U.S. Fish and Wildlife Service (USFWS).
"The wolf carcasses were discovered in a pile in the ditch just off the shoulder of the road, as though someone had driven up and dumped them off the edge of the shoulder," agency spokeswoman Tina Shaw said.
The gray wolf is currently listed by the federal government as "threatened" under the Endangered Species Act, meaning they cannot be hunted except in defense of human life. A conviction for each violation could result in up to six months in prison and a fine of up to $25,000.
The federal agency announced a reward of up to $2,500 for information leading to an arrest and conviction.
The carcasses were sent to the USFWS's national forensics lab in Ashland, Ore., the country's lone crime lab for animals, Shaw said.
"There appear to be marks from a snare on the necks of the wolves, but our forensics scientists are currently making [a] determination" into how the animals were killed, Shaw said.
Shaw added that "evidence supports that the wolves were killed elsewhere and purposely moved to this location … right on the road."
