The Crook County Sheriff's Department is asking for the public's help in the shooting deaths of three wild horses this week. A sheriff deputy found the horses shot to death in the Ochoco National Forest about 18 miles east of Prineville.   Sheriff Jim Hensley says the discovery was disturbing: “But I can tell you this is not something that happens everyday. One of the horses was pregnant and it was a gruesome sight.” If you have any information on the senseless shootings, please contact the Crook County Sheriff's Department.
