Yes, swedie, that could make more sense, but then if that's true, MS is allegedly a vicious murderer of two innocent people and only interested in saving his own hide by not going to police in either case, IMO.
OTOH, if MS hadn't actually participated in LB's murder but chose to stay in contact with DM knowing DM had murdered her, what does that say about MS? Why would MS have made such a terrible decision unless he was OK with DM's criminal behaviour and murder of LB? It was several months between the murders of LB and TB - and then a very sudden and IMO suspicious "suicide" of WM (that eventually got DM charged with his murder) and MS had invited DM and CN over to his own family's Christmas dinner that year? DM wasn't even on LE's radar until after everything came out about TB, IMO, and no charges were added until almost a year later, so I don't think MS didn't call police about DM murdering TB because MS was worried about being framed for LB's murder, I think he didn't tell police about either LB's or TB's murders because MS did play a role in both, IMO. I see no good reason otherwise that MS would have had to continue his friendship with DM and to willingly assist DM with other crimes, IMO. IMO, MS had choices and he made the wrong ones.
All MOO.
