Like you, I think more than 1 person was involved in the kidnap/murders. Maybe one person did all the killing, but more than one was involved in getting them out of the house and moving them to where they were killed. Much has been said about how the central figure managed to keep his subordinates silent all these years. Maybe he is scary and threatened the others with death if they talked. Also, the subordinates may have witnessed the killings and saw what the central figure was capable of. But, another way the central figure managed to keep the others quiet is to simply point out to them that if they rat him out, he will do likewise to them. Thus, they will by law be deemed a guilty party in a triple homicide and they too will spend the balance of their lives in prison. That is a very effective way of guaranteeing silence. MOO
