This isn't the first time decapitated goats have been found in the metro Atlanta area.

Nearly a dozen decapitated goats found in Chattahoochee River

Over the years, many things have been dumped into the Chattahoochee River.

Add dead goats to the list.

Decapitated goats.

“Whoever done it,” area resident Johnny Davis told Channel 2 Action News, “they are very cold blooded.”

Jason Ulseth of Chattahoochee Riverkeeper, who patrols the river looking to stop sources of pollution, was also taken aback.

FLASHBACK: Chattahoochee River through the years 

When he looked out from a bridge headed into Cobb County on Wednesday, he saw something unusual.

“Because I saw the body first, I was like, ‘Oh, that looks like a goat.’ And then got a little closer and saw there was no head.”

Then he saw more decapitated goats along the river, more than 10.

“People that are dumping in this river go home and drink it out of their taps,” he said, “and they don't make that connection — that they're actually polluting their own water source.”

He finds it hard to believe.

“This is pretty disturbing personally.”
