Conservation groups are offering nearly $43,000 for any information on wolves that were poisoned in Oregon this year.
The organizations Wolves of the Rockies, Trap Free Montana, The 06 Legacy Project, Greater Hells Canyon Council, the Humane Society of the United States and other private donations raised the reward for information about the wolves to $42,977, The Oregonian reported.
The poisonings, which are under police investigation, were discovered after a wolf with a tracking collar stopped moving in February, according to the Oregonian.
When state police went to the scene, the whole Catherine Pack, three males and two females, were dead. Another dead female wolf was found a month later.
Tests in April showed all six of the wolves were poisoned, with more poisoned wolves found in the following months.
“We were heartbroken to hear of these horrific and inhumane killings, and condemn in the strongest terms this atrocity,” Marc Cooke, president of Wolves of the Rockies, said.
“But this slaughter did not occur in a vacuum. We hope to see those responsible for the illegal killings brought to justice,” Cooke added.
