It has occurred to me that both the mother and the son were killed in their home. I still find it very hard to believe with the description of the son that he carried out all that. Also, what seems odd to me is that a woman with that monthly income had a honda civic. There are a lot of things that don't add up or seem strange. All the questions that are being asked are really important.
And any of these tragedies where the videos are not released are suspicious in the utmost.
