Hamilton police have released photos of a man they describe as a person of interest in connection with an east-end shooting at an after-hours party last summer that left a Toronto teen dead.

Natshon Defreitas was pronounced dead in hospital following the shooting, which police say happened at an empty office building on Beach Road around 4 a.m. on Sept. 23.

On Monday the service released photos showing a man walking and smiling with a group of other people.

Police say the images were captured at Modrn Nightclub hours before the the shooting.
