Arthur 'Jack' Schubarth, an 81-year-old Montana resident, has been sentenced to six months in federal prison for illegally breeding hybrid sheep using genetic material from endangered Marco Polo sheep. Schubarth's operation involved cloning embryos with parts imported from Kyrgyzstan, aiming to create larger hybrids for trophy hunting, a practice that has drawn significant legal scrutiny and public condemnation. U.S. District Court Judge Brian Morris noted the need to deter future genetic manipulation in wildlife, despite Schubarth's age and prior clean record. In addition to prison time, Schubarth was fined $20,000 and ordered to pay $4,000 to the U.S. Fish and Wildlife Foundation; his cloning achievement, dubbed Montana Mountain King, has been seized by authorities. Prosecutors emphasized that Schubarth's actions posed a threat to native wildlife and were driven by greed, highlighting the illegality of his operations under the Lacey Act. Schubarth expressed remorse for his actions, stating he would work his life to repair the damage done.
