Colorado Parks and Wildlife officials are offering a $1,000 reward for information that leads to an arrest or citation related to four poached and abandoned large bull elk carcasses left on four ranches in Las Animas County, according to a release from the agency Wednesday.

Of the poached elk, one was shot and abandoned whole, one was wounded and had to be put down, another was shot with the backstraps removed and the fourth had its head removed with no meat taken.

The elk were shot on Sept. 13, 26 and 27 near Stonewall and Picketwire, according to the release.

Anyone with information is encouraged to call the operation game thief at 1-877-265-6648 or email game.thief@state.co.us. Tips may be provided anonymously.

In addition to the reward, anyone willing to testify about information they provide that leads to charges is eligible for a preference point or hunting license.
