A $10,000 reward has been posted in Garfield County for information leading to the arrest and conviction of anyone found guilty of malicious killing of livestock.

Although killings haven't been reported since those of 15 cows and six calves last spring in the lower Escalante River drainage in the Glen Canyon National Recreation area, the sheriff's office reports there have been threats to ranchers in the Boulder and Escalante areas to kill their cattle.A spokesman at the office said the Earth First! organization has claimed responsibility for the threats. Threats have been received by stockmen who graze cattle on Bureau of Land Management allotments.

Sheriff Than Cooper urged those who are on the lands to be on the lookout for suspicious behavior. He appealed especially to back packers, hikers, sportsmen and those who travel through the area, asking them to report to the sheriff's office in Panguitch if they observe such activity.

The reward is offered jointly by the sheriff's department and the local cattlemen's association.
