Who killed Pahoran Jr. but couldn't be found because he was in disguise?


Kishkumen

Kishkumen ... murdered Pahoran as he sat upon the judgment-seat. And he was pursued by the servants of Pahoran; but behold, so speedy was the flight of Kishkumen that no man could overtake him. ... Therefore, Kishkumen was not known among the people of Nephi, for he was in disguise. Helaman 1:8-12
