GRAND JUNCTION, Colo. (AP) — Authorities say one of four South Carolina men who used poison arrows to hunt deer, elk and bears told them he has been using the illegal equipment in Colorado for at least 20 years.

George Plummer and Joseph Nevling, both of Timmonsville, S.C., Michael Courtney, of Florence, S.C., and James Cole, of Sumter, S.C., all pleaded guilty Tuesday to a variety of wildlife charges, including illegal taking of wildlife and illegal use of toxins in hunting. They were arrested Saturday.

According to the Grand Junction Daily Sentinel (http://tinyurl.com/oxgtfqa ), authorities said Plummer admitted using toxic arrows for years.

All four were ordered to pay several thousands of dollars in fines and court costs. The men also agreed not to hunt in Colorado over the next four years.
