Police say an argument at the party escalated into a brawl which spilled out onto the street.

At some point during the brawl the two men — aged 23 and 55 — were stabbed with an edged weapon.

Paramedics attended however the pair could not be saved.

Karl Gruber’s footy club paid tribute to him on social media, saying he was “a true gentleman at the club who wore his heart on his sleeve and let his footy do the talking.”

Superintendent Janet Stevenson said about 20 people were involved in the brawl but several people had left before police arrived.

“We need to talk to those people,” Stevenson said.

“These people hold the key.”

CCTV from a nearby home captured someone screaming “wake up, wake up” following the incident.

Stevenson could not confirm how many offenders police were looking for and said no weapons had been found.

She said the two men who were killed had a close relationship with the people who were holding the party.

“It’s tragic, you can just imagine how that family feels now — it should have been a great celebration but it’s just a dreadful ending,” Stevenson said.

She urged the people who left before police arrived to come forward.

“These people know who they are and it’s in the best interest, especially to this family, for them to contact us as soon as possible and just don’t drag this out, it’s not good for anyone.”

Anyone with information has been urged to contact Crime Stoppers.
