Ever since endangered Gray Wolves were reintroduced to Yellowstone National Park, they have thrived and spread throughout the West. California now has a wolf population residing in Lassen and Plumas counties. In 2018 the Gray Wolf known as OR-59 was shot and killed in Northern California. The U.S. Fish and Wildlife Service has been investigating the incident and recently offered a $2500 reward for information leading to the killer of OR-59. KPFA’s Vic Bedoian reports from Fresno.
