CHARLOTTE, N.C. — Three men mutilated a 300-pound llama that was protecting dozens of alpacas in an act of “pure meanness,” according to police and the owner of the farm.

The 10-year-old llama named Mighty was killed Jan. 28, and parts of her body were found in two locations on the farm in Monroe, southeast of Charlotte, according to Tammy Limer, who runs Borderline Farms.

“This llama weighed 300 pounds,” Limer said. “She (wasn’t) a little thing. It took some effort for them boys to do what they did.”

Charged in the attack were James Robert Lee, 18; Alexander Samuel Clark, 20; and Cody Wyatt Bray, 22, authorities said. They are accused of felony breaking and entering, felony larceny, second-degree trespassing and cruelty to animals.

Llamas can protect herds of sheep and alpaca from dogs and coyotes. Limer also said the llamas are also used as therapy animals for autistic children and the elderly.
