The introduction to the band of Gadianton (also known as the "Gadianton Robbers") would indicate that this group was organized by Kishkumen. However, upon the death of Kishkumen, "Gadianton, who was exceeding expert in many words, and also in his craft, to carry on the secret work of murder and of robbery . . . became the leader of the band of Kishkumen." (Helaman 2:4.)
Gadianton then led his followers into the wilderness, and they are not mentioned again in the record for several years. But, as Mormon promised, "more of this Gadianton shall be spoken hereafter." (Helaman 2:12.)
