A Rancher Cloned a Giant Sheep — Now He's in Prison (the Man, Not the Sheep)-1

Arthur "Jack" Schubarth, 81, of Vaughn, Montana, found himself at the center of a controversy that marries science, ethics, and the law. A federal judge sentenced him to six months in prison for using tissue and testicles from Marco Polo sheep — the world's largest breed — to create hybrid animals destined for captive trophy hunting. The fallout from his actions rippled through the wildlife community, leaving behind questions about the cost of bending nature to human ambition.

From Livestock Rancher to Genetic Outlaw

Schubarth ran Sun River Enterprises LLC, a sprawling 215-acre ranch specializing in alternative livestock. His operation catered to private hunting preserves, where customers paid hefty fees to shoot rare or exotic game. Prosecutors revealed that in 2013, Schubarth obtained tissue from a Marco Polo sheep hunted in Kyrgyzstan and used it to clone the animal. The result, dubbed "Montana Mountain King" or MMK, became the foundation for a breeding program that spanned multiple states and netted him hundreds of thousands of dollars.

A Scheme Worth Half a Million

Schubarth pleaded guilty in March, admitting he and five others conspired to clone the sheep and breed hybrids for trophy hunting operations in Texas and Minnesota. "I will have to work the rest of my life to repair everything I've done," Schubarth told U.S. District Judge Brian Morris at sentencing, as reported by CBS News.

The operation's scale was staggering. According to court records, Schubarth sold hybrid sheep and MMK's semen to clients in Texas, while a Minnesota resident brought 74 sheep to his ranch for insemination. The hybrids, advertised as genetically superior for trophy hunting, fetched prices up to $10,000 per animal. Prosecutors estimated the total value of the operation at between $250,000 and $550,000.

A Judge's Balancing Act

Judge Morris described his decision as a balancing act, weighing Schubarth's age and clean record against the need for deterrence. "You were so focused on getting around those rules you got off track," Morris said during the hearing, according to the Associated Press. He fined Schubarth $20,000 and ordered a $4,000 payment to the U.S. Fish and Wildlife Foundation. Schubarth must self-report to a Bureau of Prisons medical facility.

The High Cost of Greed

Prosecutors argued that Schubarth's actions endangered native wildlife and flouted federal and state laws. "His actions threatened Montana's native wildlife species for no other reason than he and his co-conspirators wanted to make more money," U.S. Attorney Jesse Laslovich said in a statement, as reported by CBS News.

Passion, Obsession, and Regret

Schubarth's attorney, Jason Holden, sought probation, describing his client as a passionate animal caretaker who let his enthusiasm cloud his judgment. "I think this has broken him," Holden told the court, adding that the scandal destroyed Schubarth's "life, reputation, and family," according to the Associated Press.

In a letter attached to his sentencing memo, Schubarth expressed shame over his actions. "I got my normal mindset clouded by my enthusiasm and looked for any grey area in the law to make the best sheep I could for this sheep industry," he wrote, as reported by CBS News. "My family has never been broke, but we are now."

A Future Full of Consequences

The consequences extended beyond the courtroom. Authorities confiscated MMK, now housed in a secure facility until it can be transferred to a zoo. Schubarth must also slaughter the remaining hybrids with Marco Polo DNA on his ranch and donate the meat to food banks.

While Schubarth faces the consequences, the case remains open for his unnamed co-conspirators. His plea agreement requires full cooperation with prosecutors. The Montana Mountain King, a product of both ingenuity and ethical failure, now serves as a cautionary tale about the limits of human intervention in nature.
