John Abernethy found the grisly remains of a deer carcass in his backyard this morning.
He suspects a cougar was the culprit.
“It must be a cougar,” he said. “It would have to be an animal that big to have eaten half of a deer.”
His Sherburn Road property is surrounded by other homes in every direction, though the wilderness is just two streets away.
