CALGARY - A defence witness has testified that an individual taller than the accused was the person who pulled the trigger in the fatal shooting of a Calgary Stampeders football player.

Nelson Lugela is on trial for second-degree murder in the death of Mylan Hicks outside a Calgary bar in September 2016.

Shelley Stevenson told court that she was serving drinks at the Marquee Beer Market the night Hicks died.

She said she remembers seeing Lugela and another man wearing a red vest in a dispute with some Stampeders players earlier in the evening.

She said she remembers the two men because they were rude to her.

Stevenson said she was outside the bar at closing time when she saw a group of men pushing and shoving, and witnessed a tall, black man in a red vest pull out a gun, raise it and shoot three or four times.

She says Lugela, who was shorter and wearing a white polo shirt, was there but he wasn't the one who fired the shots.
