The shooting occurred in the Lincoln National Forest so the case was turned over to the Forest Service, according to a report posted today by Ruidoso News.
The wild horses of Alto, NM were returned to their home range a year ago after a judge ruled that the state livestock board had taken them into custody illegally.
The incident follows the Clark Mountain wild burro shootings in California and Heber wild horse shootings in Arizona. No arrests have been made in those cases.
