Well how sure are you that it was suicide? Throughout the story their are subtle hints that Uncle George and not the Indian is the father of the baby. In the beginning of the story Uncle George is handing out Cigars to the Indians, traditionally new fathers give out cigars upon the birth of their child. Furthermore in child birth the father of the child is usually by the side of the mother, and as we can see Uncle George and not her husband is by her side. As for the death of the Indian we don't know when he dies, all we know is that he is found dead some time later. another detail is the mysterious disappearance of Uncle George after they find the husband dead, this suggests that Uncle George may have killed the father and run off. As far as suicide goes, it is very difficult to cut your own throat from ear-to-ear, this is a little gruesome, as you would have to saw through the cartilage and bone in your neck.
