According to Kakuzu one of the KinGin brothers saw his brother die and went into 6 tails mode in rage and Kakuzu somehow witnessed it. Either Tobirama killed one of them and the rest of the elite squad before the last one finally killed him, or Hiruzen got revenge and killed the KinGin brothers. I think its more likely Tobirama killed all of the Elite squad except one of the KinGin brothers who apparently finished off Tobirama(most likely the bro who got enraged and went into 6 tails V2 mode)
