The radio-collared female gray wolf was found near Rio Blanco County Road 60 on April 6, 2009 after researchers received the mortality signal from her GPS tracking collar. Toxicology tests performed at the National Fish and Wildlife Forensic Laboratory showed the two-year-old gray wolf, which had been captured and collared as part of a Montana research project, died from ingesting a banned poison known as Compound 1080. It is suspected the wolf ingested the poison near the site where she was found.
