Search warrant documents obtained by CBC give a sense of the violence that exploded inside the house at 227 Avenue F South.

"They confirmed blood was observed inside"

The documents tell how officers who interviewed the first victim at the FasGas station determined he had come from a house behind the White Buffalo Youth Lodge. He was searched and found to be carrying two unlabelled pill bottles filled with a large number of unknown pills.

Officers already knew of suspicious activity at a house behind the White Buffalo. They went there -- 227 Avenue F South -- and noticed blood inside the door.

"While clearing the residence, he observed blood all over the main floor, from the front to the back," the warrant said.

"The home was quite messy and the rear entrance appeared to be barricaded with a stick. While in the back yard, he observed some chairs, clothing band what appeared to be blood on the ground."
