Exactly. Unless we were party to the situation we have only what the accused my have said for reference as the only other witness is deceased. It has been proven that SL is a liar, so why wouldn't he lie to family? I will admit that no evidence of forced entry doesn't mean it didn't happen, only that they couldn't find any. With the added info of the stolen garage door opener, I'm back to wondering if SL had "help".
As to the repeated statements of gun powder residue being transferred to SL, why would the assailant fire the gun and THEN restrain the bigger threat? Also, we don't know what they tested. It could have been hands, clothing, or both.
