The facts should speak volumes

I always find myself at the same place when I go over all the news articles involving the case against Shane Lawshe. I can not quite understand why the police were convinced it was him and did not investigate the ex-husband.
It seems the X had motive and perhaps opportunity. Shane had no motive. He also did NOT rape the woman. He was having an affair with her.....its not so unheard of. I realize it might make the children feel uncomfortable to know this...and maybe they would even have some problems accepting it...but I dont think that their mother would want them to wish someone dead that she cared about and that never did her any harm what so ever. I think she would want the real killer to be found. Maybe I am wrong about her because I did not know her.
