When they arrived, police found two men with gunshot wounds in a parking lot. The first, a man in his 30s, was rushed to hospital and was later pronounced dead.
The second man — in his 20s — was taken to hospital with non-life-threatening injuries.
In an update on Sunday, police said the male suspect was five-feet, six-inches tall with a slim build. Police said he was last seen wearing a light coloured surgical mask, shiny puffer jacket with a hood, light pants and black running shoes.
The force also said it had identified a white Nissan sedan as a “suspect vehicle.”
Police said he was “considered armed and dangerous.”
