I think somethnig to keep in mind is that Sandra L is a relentless woman - and the fact that she's so public with her 'findings' that often prove to be nothing (this may be more trun in the case of LM's mother)> she puts the families of the murder victim through a lot of hell and pain.
So the families are in their rights to HATE Sandra Lean and have STRONG emotions for her - that makes sense to me.
If someone killed my sister and was convicted - then this Sandra Lean woman was in the press sprouting what I believed to be lies in order to get the killer out of jail.........God, she'd be my enemy.
