Alberta’s police watchdog is seeking witnesses in two police shootings that killed one man and left another in critical condition.

The first shooting took place in the early evening of December 12 in Fort McMurray.

The Alberta Serious Incident Response Team (ASIRT) says a woman called police after hearing crying in the basement apartment she was renting.

Officers arrived and entered the suite for a welfare check, at which time a man was seen fleeing through a window into the yard.

ASIRT said a police officer followed him and shot him. The man was taken to hospital, where he remained in critical condition Friday.

Only the man and the officer were in the yard at the time of the shooting, ASIRT said, and the officer was not wearing a body camera.

The second shooting occurred in Cold Lake on the night of December 14.

Around 8 p.m., a fight was reported between two men, one of whom was armed with a knife, near 50th Street and 43rd Avenue.

The fight had ended before officers arrived, but Mounties found a man matching the description of the gunman in the area.

ASIRT said the man pulled out the knife and approached officers. One officer shot the man multiple times with a gun while another fired a TASER.

The man was taken to hospital where he died.

Anyone who has seen a shooting or has security or dash cam footage is asked to contact ASIRT at 780-644-1483.
