SPOKANE, Wash. — The reward for information regarding the killing of two wolves in northeastern Washington state has grown to $20,000.

The Center for Biological Diversity and Cascadia Wildlands on Monday said they had doubled a previously announced reward by Conservation Northwest for information leading to conviction in the killing of the wolves.

Over the weekend, officials for the state Department of Fish and Wildlife announced that two wolves that were being monitored had been found shot to death.

Wolves are a protected species across the state of Washington. Poachers can face fines and jail time.
