Burialplace Of The Victims Of Lamech Found?

Has the burialplace of the victims of Lamech been found?  In Genesis chapter 4, we read of the genealogy of Cain.  Lamech is the 3x great-grandson of Cain who also happened to kill two men, specifically, a man and a young man.  Although it might be easy to dismiss this assertion as false because Lamech presumably lived in the land of Nod all his life, the Bible merely states that he killed two people, but it does not say who they were or where they were buried.  This discovery fits the biblical narrative.
