My conclusion:
The murderer must be son 2.
My reason:
The statement of son 1 seems to be pretty honest and related to the situation, it's reasonable. And so does apply to his wife (1) and son (1).
Now getting to the statement given by son 2, at first it seems pretty clear, but things start to get weird when he starts to give answers without asking. He says he has a broken leg, so he can't jump off or even walk. It was not asked, and he gets in doubt. The another layer which gets him into doubt is the statement given by his wife, it was much short and not detailed, a common sign that some one is speaking a lie or trying to hide it. #Confession#spookiansclub#horrorhues#schhoh#sc_cid2
