Shikamaru later revealed in the 4th war that the KinGin bros did indeed kill Tobirama. Maybe they were part of the Kinkaku Squad and the Kinkaku Squad left Kumo with them.. their was supposed to be peace between Kumo and Konoha at that time so that makes sense. Kinkaku and Ginkaku had their own band of 20 Ninja including themselves and sought to finish off the 2nd Hokage which makes sense.
