Is it possible that Darlie inflicted her injuries on herself AFTER Darin came downstairs? Darin said he didn't even notice that Darlie's neck was cut when he came downstairs. Could she had done it during the time she was getting towels and wetting them down in the kitchen sink? Does her blood trail suggest she may have done it then? Did she go out by the utility room or garage after Darin came downstairs? Sorry, if this has been discussed.
