(Salem, OR) -- The reward continues to grow for information that leads to an arrest or citation in the poisoning of wolves in northeast Oregon. The Oregonian reports the reward now stands at nearly 43-thousand dollars thanks to donations from conservation groups Wolves of the Rockies, Trap Free Montana and The 06 Legacy Project. Earlier this year, eight wolves died from poisoning in Union County. Oregon State Police are investigating and they're asking for information that helps identify a suspect.
