The pair had recently seemingly adopted a young sorrel colt named Junpei, according to the reward posting.

At last report, Junpei’s whereabouts were unknown.

“Harassing, capturing or killing wild horses is illegal and punishable by up to a year in prison and/or a fine,” said BLM West Desert District Manager Mike Gates in the released statement. “The BLM takes our responsibility seriously to protect these animals and is committed to holding accountable whomever is responsible for this unconscionable act.”

In 1971, the U.S. Congress passed legislation to protect, manage, and control wild horses and burros on the public lands. The Wild Free-Roaming Horse and Burro Act declared these animals to be “living symbols of the historic and pioneer spirit of the West,” the BLM statement continues. Congress further declared, “wild free-roaming horses and burros shall be protected from capture, branding, harassment, or death and that they are an integral part of the natural system of the public lands.”
