WINNIPEG - Aboriginal leaders are calling for an investigation into the slaughter of almost three dozen caribou along a Manitoba winter road.

A northern chief discovered the bloody carcasses of 30 animals near Lynn Lake.

Their antlers had been removed, but the meat and hide were left to rot.

Grand Chief David Harper, who represents northern First Nations, says the slaughter is a huge waste.

He says aboriginal hunters would never have done such a thing because First Nations use every part of the animal.

The chiefs are also calling for more provincial patrols on winter roads to prevent something similar from happening again.
