Shawn Malcarne, Kyle Roscetti Stabbed 4 Alpacas To Death For Fun, Left Nose Ring At Scene, Cops Say

Two men charged with the thrill killing of four pet alpacas in Connecticut will soon head to court after recently pleading not guilty.

Kyle Roscetti, 21, and his buddy Shawn Malcarne, 23, were arrested in April after they lured the pets to a fence and then stabbed them, cops told NECN at the time.

The alpacas' Essex-area owner was distraught to find her animals dead on Dec. 23. It was the third time animals on her property had been attacked.

"I wish whoever's doing this would kill themselves and stop hurting these guys," she said through tears at the time. "You can't imagine. They're such puppy-like, gentle creatures, alpacas."

One of the alleged perps left a nose ring at the scene, which led cops to them, the Associated Press reported.

Roscetti and Malcarne wouldn't talk to reporters about a motive for the alleged attack, but prosecutors say they did it for sport. They pleaded not guilty to cruelty to animals and other charges in earlier court appearances.

Roscetti is due in court on July 19, and Malcarne has a hearing on June 28.
