You know, death really isn't sufficient.
But, yeah, I know we need a trial first... I hate to think of that little girl having to testify about the rapes though. But its in the constitution you get to confront your accuser.
He is being charged with 3 counts of murder and 3 counts of kidnapping at this point. It sounds like it is for tying up and murdering the older brother, mother and mothers boyfriend.
Her testimony of his confession alone should be enough to put this guy on death row without putting her through that.
