Peter Hagan, 16, was found stabbed in a stairwell in Neville Gill Close, in the early hours of Sunday morning and confirmed dead at the scene.
A post-mortem examination will resume later.
Nine people have been arrested, with eight being released on bail. One remains in police custody.
Detective Chief Inspector Nick Scola, of the Homicide and Serious Crime Command, said: “I need to trace everyone at that party.
