Police are trying to determine if a bloody scene at a New Jersey cemetery is tied to a religious or gang-related ceremony.

Six bloody machetes, six dead chickens and one injured bird were found along with blood on tombstones in Rosehill Cemetery in Linden.

Police Lt. Jeff Clark tells the Home News Tribune the evidence was recovered in Sections 38 and 50.

Clark says cemetery workers said the blood can be washed off the tombstones.
