EDISON - The NJ SPCA says it is investigating a "major case" in Warren County.

Details on the probe are vague, but the organization said in a post on its Facebook page that it involves "two properties with numerous deceased livestock animals." The post described the case as "horrific" with circumstances that have "stunned" officers.

The post did not reveal where in Warren County the properties are located. It said that the SCPA is working to determine the animals' causes of death.

News 12 New Jersey is working to get more information on the investigation.
