Two decapitated goats that were found stuffed inside plastic bags on Long Island were slaughtered in a “ritualistic sacrifice,” authorities said.

The Suffolk County SPCA made the gruesome discovery on Thursday behind a Burger King at 96 Broadhollow Road in Farmingdale.

The headless goats had been put inside black bags “along with other items that would suggest a ritualistic animal sacrifice,” according to Roy Gross, chief of the Suffolk County SPCA.

The organization is offering a $2,000 reward for information leading to the arrest and conviction of those responsible for mutilating the animals.

“All too many times these gruesome finds are discovered not only by adults but occasionally by children,” the SPCA said.

Those with any information can contact the Suffolk County SPCA at 631-382-7722.
