Pennsauken police responded to the scene at the La Hacienda Restaurant on the 5700 block of Westfield Avenue.
It was around 2:30 a.m. when a melee broke out among a group of men. One of them pulled out a knife and stabbed four others.
21-year-old Jacobo Medina and 22-year-old Javier Medina died from their injuries. The two men are not related.
Another victim was taken to Cooper University Hospital for treatment. The fourth is said to have received minor injuries.
Police say the victims were attending a baptism party at the restaurant Saturday night. The party ended about 2:00 a.m. and as attendees gathered outside the restaurant, a verbal dispute between members of the baptism party and another group escalated into a brawl.
Police are now looking for a dark colored minivan, which fled the scene with 8 to 10 men inside.
Anyone with information is urged to contact Camden County Prosecutor's Office Investigator Jeff Long at (856) 225-8400 or Pennsauken Police Detective Phil Olivo at (856) 488-0080.
